ANSI/DEC compatible parser described by\n * Paul Williams (https://vt100.net/emu/dec_ansi_parser).\n *\n * To implement custom ANSI compliant escape sequences it is not needed to\n * alter this parser, instead consider registering a custom handler.\n * For non ANSI compliant sequences change the transition table with\n * the optional `transitions` constructor argument and\n * reimplement the `parse` method.\n *\n * This parser is currently hardcoded to operate in ZDM (Zero Default Mode)\n * as suggested by the original parser, thus empty parameters are set to 0.\n * This is not in line with the latest ECMA-48 specification\n * (ZDM was part of the early specs and got completely removed later on).\n *\n * Other than the original parser from vt100.net this parser supports\n * sub parameters in digital parameters separated by colons. Empty sub parameters\n * are set to -1 (no ZDM for sub parameters).\n *\n * About prefix and intermediate bytes:\n * This parser follows the assumptions of the vt100.net parser with these restrictions:\n * - only one prefix byte is allowed as first parameter byte, byte range 0x3c .. 0x3f\n * - max. two intermediates are respected, byte range 0x20 .. 0x2f\n * Note that this is not in line with ECMA-48 which does not limit either of those.\n * Furthermore ECMA-48 allows the prefix byte range at any param byte position. Currently\n * there are no known sequences that follow the broader definition of the specification.\n *\n * TODO: implement error recovery hook via error handler return values\n */\nexport class EscapeSequenceParser extends Disposable implements IEscapeSequenceParser {\n public initialState: number;\n public currentState: number;\n public precedingJoinState: number;

ANSI/DEC compatible parser described by\n * Paul Williams (https://vt100.net/emu/dec_ansi_parser).\n *\n * To implement custom ANSI compliant escape sequences it is not needed to\n * alter this parser, instead consider registering a custom handler.\n * For non ANSI compliant sequences change the transition table with\n * the optional `transitions` constructor argument and\n * reimplement the `parse` method.\n *\n * This parser is currently hardcoded to operate in ZDM (Zero Default Mode)\n * as suggested by the original parser, thus empty parameters are set to 0.\n * This is not in line with the latest ECMA-48 specification\n * (ZDM was part of the early specs and got completely removed later on).\n *\n * Other than the original parser from vt100.net this parser supports\n * sub parameters in digital parameters separated by colons. Empty sub parameters\n * are set to -1 (no ZDM for sub parameters).\n *\n * About prefix and intermediate bytes:\n * This parser follows the assumptions of the vt100.net parser with these restrictions:\n * - only one prefix byte is allowed as first parameter byte, byte range 0x3c .. 0x3f\n * - max. two intermediates are respected, byte range 0x20 .. 0x2f\n * Note that this is not in line with ECMA-48 which does not limit either of those.\n * Furthermore ECMA-48 allows the prefix byte range at any param byte position. Currently\n * there are no known sequences that follow the broader definition of the specification.\n *\n * TODO: implement error recovery hook via error handler return values\n */\nexport class EscapeSequenceParser extends Disposable implements IEscapeSequenceParser {\n public initialState: number;\n public currentState: number;\n public precedingJoinState: number;

ANSI/DEC compatible parser described by\n * Paul Williams (https://vt100.net/emu/dec_ansi_parser).\n *\n * To implement custom ANSI compliant escape sequences it is not needed to\n * alter this parser, instead consider registering a custom handler.\n * For non ANSI compliant sequences change the transition table with\n * the optional `transitions` constructor argument and\n * reimplement the `parse` method.\n *\n * This parser is currently hardcoded to operate in ZDM (Zero Default Mode)\n * as suggested by the original parser, thus empty parameters are set to 0.\n * This is not in line with the latest ECMA-48 specification\n * (ZDM was part of the early specs and got completely removed later on).\n *\n * Other than the original parser from vt100.net this parser supports\n * sub parameters in digital parameters separated by colons. Empty sub parameters\n * are set to -1 (no ZDM for sub parameters).\n *\n * About prefix and intermediate bytes:\n * This parser follows the assumptions of the vt100.net parser with these restrictions:\n * - only one prefix byte is allowed as first parameter byte, byte range 0x3c .. 0x3f\n * - max. two intermediates are respected, byte range 0x20 .. 0x2f\n * Note that this is not in line with ECMA-48 which does not limit either of those.\n * Furthermore ECMA-48 allows the prefix byte range at any param byte position. Currently\n * there are no known sequences that follow the broader definition of the specification.\n *\n * TODO: implement error recovery hook via error handler return values\n */\nexport class EscapeSequenceParser extends Disposable implements IEscapeSequenceParser {\n public initialState: number;\n public currentState: number;\n public precedingJoinState: number;

ANSI/DEC compatible parser described by\n * Paul Williams (https://vt100.net/emu/dec_ansi_parser).\n *\n * To implement custom ANSI compliant escape sequences it is not needed to\n * alter this parser, instead consider registering a custom handler.\n * For non ANSI compliant sequences change the transition table with\n * the optional `transitions` constructor argument and\n * reimplement the `parse` method.\n *\n * This parser is currently hardcoded to operate in ZDM (Zero Default Mode)\n * as suggested by the original parser, thus empty parameters are set to 0.\n * This is not in line with the latest ECMA-48 specification\n * (ZDM was part of the early specs and got completely removed later on).\n *\n * Other than the original parser from vt100.net this parser supports\n * sub parameters in digital parameters separated by colons. Empty sub parameters\n * are set to -1 (no ZDM for sub parameters).\n *\n * About prefix and intermediate bytes:\n * This parser follows the assumptions of the vt100.net parser with these restrictions:\n * - only one prefix byte is allowed as first parameter byte, byte range 0x3c .. 0x3f\n * - max. two intermediates are respected, byte range 0x20 .. 0x2f\n * Note that this is not in line with ECMA-48 which does not limit either of those.\n * Furthermore ECMA-48 allows the prefix byte range at any param byte position. Currently\n * there are no known sequences that follow the broader definition of the specification.\n *\n * TODO: implement error recovery hook via error handler return values\n */\nexport class EscapeSequenceParser extends Disposable implements IEscapeSequenceParser {\n public initialState: number;\n public currentState: number;\n public precedingJoinState: number;

The negotiation seam proves every initial connection and reconnect offers V1, the same-build relay advertises V1 without launch flags, old clients remain token-free, and method-not-found peers fall back without installing source ACK publication. The joined source-intake/multiplex oracle blocks renderer or headless serialization, admits one snapshot-covered span and one trailing span, requires replacement reservation only after the authoritative sequence is known, advances upstream ACK eligibility exactly to the covered boundary after SnapshotEnd, and delivers then ACKs the trailing span through the ordinary live path without cancellation. Source-range ledger and multiplex seams additionally require cumulative byte ACK 40 then 100 for one 100-byte frame to release exact byte credit without early source settlement, admit a contiguous higher-generation recovered token while the prior token remains unsettled, and reject stale stream or source generations without releasing in-flight byte credit. Replacement reservation rolls back every earlier span on a later failure, commit requires the exact frozen transfer states, and an authoritatively reclaimed covered span rejects commit without local trim authority while rollback removes the reservation idempotently. The exit-deadline oracle publishes a source-backed desktop projection, advances a fake clock to cancellation, and requires one projection transfer, proof commit, preparation, and final exit with no provider close, retained obligation, duplicate finalization, or process-lifetime cancellation tombstone; a second controlled proof remains pending across generation close and must never publish final exit, while both paths release the renderer preparation lease exactly once. The model-migration oracle accepts span A, blocks span B's raw emulator completion, begins disconnect migration, and proves no checkpoint or reconnect attach can remain at A; releasing B advances the exact checkpoint to B and projects B once. Its fake-clock arm reaches the 10-second deadline, requires checkpoint-unavailable, one exact model reset, zero retained admission charge and timers, and no effect from late raw settlement. Its two-PTY failure arm rejects one running raw callback under an active exact migration and requires one checkpoint-unavailable result, one model reset, zero provider closes, retained sibling checkpoint and transport liveness, zero charges and timers, and an unaffected other generation; a non-migrating sibling oracle still requires generation close.

On exact pre-fix HEAD 939719443, the split-pane store, fresh-spawn, and reattach oracles failed because the first success removed pending authority and the sibling could not bind; the same three oracles pass after live bindings retain the exact attempt ID. On exact committed HEAD d501f2e96, primary-exit-before-sibling and primary/non-primary split-detach oracles failed because live authority was deleted during the empty gap or transferred to only one resulting tab; all three pass after continuation-gap preservation and two-sided detach projection.

On exact committed HEAD 9fa84dacf, the production-manager in-progress oracle rejected the fresh authority and the forward-removal barrier delayed stale transport cancellation; both pass after replacement starts cancellation immediately, shares concurrent fresh callers, and waits for teardown before connecting. On exact committed HEAD e5ba9a9e5, overlapping disconnect allowed a replacement connect before forward teardown completed and delayed transport cancellation behind that barrier; disconnect, removal, and terminate now share a target lifecycle barrier, start transport cancellation immediately, retain captured-session identity, and admit the replacement only after cleanup. On exact committed HEAD 9a29e7a81, a rejected forward teardown short-circuited the lifecycle while transport disconnect was pending, removal left its captured relay session alive, same-turn connect escaped admission, and reset remained outside the target barrier; the exact failure oracles pass after both cleanup branches settle, captured sessions always retire, admission is authority-fenced, and reset shares the barrier. On exact committed HEAD 47c7198f2, reset's remaining bespoke forward teardown could still reject after authority rotation but before captured-session retirement; reset now uses the same hardened session teardown and a failed reset remains cleanly retryable.

Orca orchestration proposal

+

Strong primitives. Little magic. No orchestration product inside the product.

+

+ Orca should make it intuitive for a coordinating agent to start workers, communicate, + wait, observe output, and recover safely. Orca supplies dependable building blocks; + the agent decides the orchestration strategy. +

+ +
+ CLI and runtime only + agent-directed + multi-server capable + explicit effects + no commit tracking +
+ +
+ +
+ The common agent loop +

+ Create and bind one Run for the coordination effort; after that its ID is carried + automatically. Create tasks, start workers on this or another connected Orca + server, send messages, wait for inbox mail, and read or stop workers. Options + refine those operations without adding policy. +

+
+
+ +

+ The test for the design is simple: after reading a few examples, an agent should be + able to predict what every command creates, reuses, blocks on, and returns. +

+
+ +
+
+

What we learned

+

The current problems are coordination problems, not missing product surfaces.

+

+ The research found real reliability gaps, but the earlier proposal responded by + adding a scheduler, integration subsystem, dashboard, and large control-plane model. + Those additions would make the common agent workflow harder to understand. +

+
+ +
+
+

Current

+

Lifecycle mail arrives through prompt injection

+

+ Messages persist, but coordinator delivery may wait for the agent to pause. If it + keeps polling or working, messages can collect and flood the editable input after + a manual interruption. +

+
+ +
+

Needed

+

A structured, blocking inbox call

+

+ Typed worker lifecycle messages return from a pending tool request or the next explicit + read. Routine lifecycle delivery never writes into the coordinator's prompt. +

+
+
+ +
+
+

Current

+

Starting a worker is assembled from low-level pieces

+

+ Creating a worktree may already create a terminal, but an agent can miss that and + create another terminal before launching the worker. +

+
+ +
+

Needed

+

One composed start operation with full topology and setup choices

+

+ The operation composes existing worktree, setup, terminal, and agent creation and + returns exactly which resources it created or reused. +

+
+
+ +
+
+

Current

+

Terminal scrollback is treated as agent history

+

+ Full-screen TUIs can redraw or discard the useful conversation, making terminal + reads incomplete or misleading. +

+
+ +
+

Implemented

+

Exact structured output with a truthful fallback

+

+ Orca reuses its pane-scoped hook association to read a supported Codex, Claude, + OpenClaude, or Grok transcript. When it cannot prove that source, it returns + labeled bounded terminal output instead of guessing a session. +

+
+
+ +
+
+

Current

+

Results are mostly worker assertions

+

+ Orca verifies that the active dispatch reported worker_done, but the + summary, changed files, tests, and report path come from the worker. +

+
+ +
+

Needed

+

Be explicit about what Orca observed

+

+ Keep lifecycle authority separate from worker-reported content. Do not add commit, + test, merge, or integration tracking merely to make the report appear stronger. +

+
+
+
+ +
+
+

Design rules

+

Reliability should live underneath a small interface.

+

+ Strong primitives have narrow, testable contracts. They do not need to expose every + mechanism used to make the contract safe. +

+
+ +
+
+ 01 +

The coordinator owns strategy

+

+ The agent chooses decomposition, ordering, parallelism, placement, review, and when + to wait. Orca does not schedule ready tasks automatically. +

+
+
+ 02 +

Every effect is visible

+

+ Responses say which connected server, worktree, setup, terminal, execution host, + and agent were created or reused. Defaults are reported, not hidden. +

+
+
+ 03 +

Simple default, explicit escape hatch

+

+ The common path needs few arguments and preserves worktree/setup choices. Uncommon + custom launches stay on the existing low-level commands instead of bloating start. +

+
+
+ 04 +

Observation is honest

+

+ Orca distinguishes observed process state from worker-reported claims and labels + the source of transcript or terminal output. +

+
+
+ 05 +

Remote ambiguity stays ambiguous

+

+ A disconnect after a remote mutation returns outcome_unknown. Orca + does not silently repeat a command that may have succeeded. +

+
+
+ 06 +

Safety is not orchestration policy

+

+ Stable identity, stale-worker fencing, and owner routing prevent corruption. They + do not choose what work should happen next. +

+
+
+ +

+ A feature belongs in the core only if it makes an existing primitive safer or clearer. + Tracking extra domain facts—commits, merges, budgets, priorities, or organizational + roles—is not automatically a stronger primitive. +

+
+ +
+
+

Primitive 1 · Scope and identity

+

Four public concepts, each with one job.

+

+ A Run prevents unrelated coordination efforts from mixing. Tasks describe work, + Dispatches authorize workers, and Messages communicate. Existing worktree and + terminal resources remain independently usable. +

+
+ +
+
+

Run

+

A lightweight namespace and stable coordinator mailbox. It never schedules work.

+
+
+

Task

+

A durable description, status, and optional dependencies. Creating it starts nothing.

+
+
+

Dispatch

+

One supervised worker assignment and its current lifecycle authority.

+
+
+

Message

+

Durable communication or a typed lifecycle report returned through the inbox.

+
+
+ +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Persisted worker stateTask state and allowed next action
starting / readyTask is dispatched; only show, read, message, or stop may act on it.
start_unknownTask is blocked; recover the same request receipt, inspect, stop, or abandon.

+
+ +
+ + + + + + + + + + + + + + + + + + + + + +
Run operationExact effect
run-create + Creates a run and stable coordinator mailbox on the coordinator's selected + Orca server—its Run home—then binds the current coordinator terminal as its + active consumer. +
run-use --id run_123 + Explicitly binds or rebinds the current terminal to that run. Rebinding fences + the prior consumer generation and cancels its waiter. A terminal has at most + one active run binding. +
run-current / run-list / run-showReports bindings and state without changing tasks, workers, or mail.
+
+ +
+
+

Run IDs stay out of the common path

+

+ A command resolves the run only from explicit --run or the current + terminal binding—never from a worktree or an “exactly one candidate” guess. + Commands return the resolved Run or runId where it is needed for later + control; agents do not carry a separate resolution-mode field. +

+
+
+

Low-level commands remain run-free

+

+ Ordinary worktree, terminal, and full-handoff commands do not create or require a + Run. Runs exist only for supervised coordination that needs durable grouping. +

+
+
+

One home, workers anywhere

+

+ A Run has one home server that owns its tasks and inbox. A Dispatch may point to a + worker on any connected Orca server; Orca relays that worker's messages back to the + home automatically. +

+
+
+ +

+ ELI5: a Run is a folder label plus a return address. It keeps one coordination + effort's tasks and mail together and gives workers on your Mac or Windows server the + same stable place to reply. + Create or select it once, then ordinary orchestration commands inherit it. It does + not create resources, choose workers, schedule tasks, or group projects. +

+ + + + + +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Canonical commandCompatibility decision
run-create/list/show/use/currentNew lightweight scope commands. They never decompose or schedule tasks.
task-create/list/updateKeep the current flat command names and add Run association.
dispatchKeep as the low-level binding to an exact existing terminal.
worker-start/show/read/stop/abandonNew composed supervised-worker operations.
send/ask/reply/checkKeep and strengthen the current message operations.
Current scheduler-like orchestration run --spec + Must be removed or renamed in Phase 0 before run-* can ship. It is + not an alias for a lightweight Run and is not part of this scheduler-free + design. +
+
+ +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
IDWho normally carries it
runIdThe terminal binding carries it; agents pass it only to override context.
taskIdThe coordinator uses it for dependencies and worker start.
dispatchId + Receipts and worker preambles carry it; show, read, stop, abandon, retry, and + lifecycle reports use it. +
deliveryIdThe current mailbox consumer carries only its last unacknowledged delivery.
messageId / threadId + reply takes a message ID and infers its thread. Agents do not + manage a separate question identifier. +
Resource IDsReceipt data until an agent explicitly reads, stops, or reuses that resource.
RPC request ID + The client transport creates it automatically. Agents only echo the returned + retry token after an unknown outcome; they never invent one. +

Primitive 2 · Supervised worker start

+

One request, predictable behavior for every topology.

+

+ worker-start is one synchronous composition of existing worktree, setup, + terminal, and dispatch operations. It is not a background executor, external + transaction, or placement engine. The coordinator chooses the topology; Orca returns + only after the composition is ready, failed, or honestly unknown. +

+
+ +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
TopologyDefault terminal behaviorSetup behavior
Current worktree + Create one fresh agent terminal. Never reuse the coordinator terminal or an + arbitrary idle terminal. Reuse requires explicit --terminal. + not_applicable; do not rerun setup or configured tabs.
Named existing worktreeCreate one fresh agent terminal; reuse only an explicitly selected terminal.not_applicable; creation-time setup is not replayed.
New child worktree + Use agent-first worktree creation and reuse its returned agent terminal. Never + create a second shell/agent terminal. + + Default to run. Setup and agent launch start side by side unless the + repository explicitly uses wait-for-setup. skip or + inherit must be explicit. +
New top-level worktreeSame agent-first behavior, with top-level Orca lineage. + Same setup default: run a configured hook; use an explicit escape hatch only + for a concrete reason. +
+
+ +
+
+

Worktree option parity means pass-through

+

+ The exact repository selector, name, base branch, child/top-level lineage, setup, + and display/comment metadata are validated and passed to the existing worktree + primitive. --on already chooses the connected Orca server, so V1 does + not add a second project/host placement vocabulary to worker-start; + agents may use low-level worktree create when that convenience selector + is important. +

+ +
+
+

Choose a connected server only when needed

+

+ The default is the Run home. Use --on windows (a saved Orca environment + name or ID) only to place a worker on another connected server. V1 resource IDs + are server-scoped, so every remote existing worktree or terminal also requires + --on. Orca never guesses an owner from a same-looking ID and echoes the + resolved server name in the receipt. +

+
+
+

Agent selection is honest

+

+ When creating a terminal, V1 requires an explicit --agent that resolves + through Orca's configured launcher before any effect. Composed start does not + promise custom model, environment, or arbitrary command arguments that agent-first + worktree creation cannot actually pass through. +

+
+
+

Setup is the safe default

+

+ For every new worktree, omitted --setup resolves to + run. If a setup hook exists, Orca launches it; if none exists, the + receipt says not_configured. Preserve the repository's existing + setupAgentStartupPolicy: its default is start-immediately, + so setup does not delay agent launch or task delivery. Only an explicit + wait-for-setup policy gates the agent. An agent may choose + skip or inherit only for a specific reason it states in its + work log. Orca trusts that judgment and adds no approval gate. +

+
+
+

Supervised means lifecycle injection

+

+ Task and dispatch input is delivered only after agent readiness. Ordinary + worktree/terminal commands remain the full-handoff path without lifecycle duties. +

+
+
+ + + + + +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Placement/federation errorMeaning
server_requiredThe selected runtime cannot provide connected-server orchestration.
worktree_not_found_on_serverThe exact worktree does not exist on the selected worker server.
terminal_worktree_mismatchThe exact terminal is not owned by the selected worktree.
resource_server_mismatch + A worker-server receipt names a different Dispatch or authenticated Run home; + Orca never adopts that attachment. +
agent_unconfiguredThe requested launcher is unavailable; no worktree or terminal was created.
+
+ +
+ + + + + + + + + + + + + + + + + + + + + +
Task acceptanceWorker-start effect
First start + Requires a ready Task with no current Dispatch. The runtime creates the + Dispatch and moves the Task to dispatched in one local transaction before + running the composed effects. +
Replacement attempt + Requires --retry-of naming the Task's current failed, stopped, or + abandoned Dispatch while the Task is failed or blocked. Start creates the next + Dispatch generation and moves the Task back to dispatched atomically; the agent + never performs a preparatory task-update. +
Anything else + Return task_not_startable naming the rejected Task/Dispatch and + perform no worker effects. Completed work gets a new follow-up Task; an unknown + or nonterminal Dispatch must first be inspected, stopped, or abandoned. +
+
+ +

+ ready has one testable meaning: the selected agent terminal reached + tui-idle, the local or remote Dispatch attachment is durable, and the + lifecycle preamble plus task input was accepted. Under the default + start-immediately policy, setup may still be running and its exact state is + returned in the receipt; its outcome never gates readiness, even if failure is observed + before the agent reaches tui-idle. Under an explicit + wait-for-setup repository policy, setup must complete successfully before + agent launch and task injection. Agent-first worktree creation launches without the + task prompt so Orca can establish authority before injection. The effective timeout + and startup policy are echoed in every receipt. + A successful gated receipt reports setup succeeded. A confirmed setup + spawn/script failure reports failed before task input, while a timeout may + honestly retain running rather than inventing a failure. +

Start stateMeaning and next action
ready + Agent is ready and lifecycle input was accepted. The return receipt contains + every created or reused effect; no separate startup notice is required. +
failed + Return the failed stage, last error, residual resources, Task/Dispatch state, + and the durable mutation receipt. The composition itself has returned, but any + surviving setup, terminal, or agent process is listed honestly as a residual + resource; Orca never implies that failure cleaned it up. The coordinator + chooses the matching recovery branch below. +
outcome_unknown + The connection failed after an effect may have happened. Return the operation + stage, mutation.requestId, durable effects/residuals, and exact + worker-show/worker-abandon commands. A replacement is + rejected until inspection proves it safe or the coordinator explicitly + abandons the old Dispatch. +
+
+ +
+ + + + + + + + + + + + + + + + + + + + + + + + + +
Unknown-start recoveryExact contract
Query and reconcile + worker-show --dispatch dispatch_7 routes from the Run home to the + owning worker server and execution host. If its durable receipt proves the + original worker became ready, failed, or stopped, the home reconciles that same + Dispatch; no separate adopt operation exists. +
Safe retry + --retry-of dispatch_7 links a new attempt but does not silently + reuse prior placement. The coordinator repeats an explicit valid topology and + agent/terminal choice, which may deliberately differ from the old attempt. A + new Dispatch is allowed only after the prior one is failed, stopped, abandoned, + or reconciled as no-effect. While it remains unknown, return + task_not_startable without mutation. +
Explicit stop + worker-stop --dispatch dispatch_7 may fence a + ready or start_unknown Dispatch. The owning server + closes a terminal only when its durable attachment still matches the exact + pane and process incarnation. Unattached, missing, exited, or identity-changed + workers become stop_unknown with no process action. If the remote + server durably stopped the exact worker but its response was lost, a later + worker-show reconciles that authoritative stopped receipt. +
Explicit abandon + worker-abandon --dispatch dispatch_7 fences future lifecycle + mutations from that Dispatch and records every possibly-live resource. It sends + no remote command, claims no process stopped, deletes nothing, and warns that a + concurrent worker may remain. The coordinator may then start a replacement. + Abandoning an older superseded Dispatch is a no-op and cannot block or rewrite + the replacement Task. +
+
+ +

+ The Dispatch ID is the worker identity. Do not add another agent-facing start ID. + Every mutating CLI result includes one opaque mutation.requestId for + recovering that exact request after a lost response; agents never invent it. A + transport failure exposes the same value as orchestrationRequestId in its + error recovery data. Semantic retry + explicitly names the prior Dispatch ID and never replays an unknown effect. After a + remote start, show, read, stop, abandon, and message routing use the Dispatch receipt; + the agent does not repeat --on for those controls or carry server IDs. A + replacement worker-start is a new placement decision and names its target + again. +

+ + +
+ +
+
+

Primitives 3 and 4 · Message and wait

+

Structured mail is inbox-only, durable, and explicitly consumed.

+

+ The inbox is an agent API, not product UI and not terminal input. It strengthens + Orca's existing message store and check --wait; it does not add an Event + subsystem or a second orchestration engine. +

+
+ +

+ send, ask, reply, completion, heartbeat, and runtime + notices only persist structured state and wake a pending tool waiter. Only explicit + dispatch --inject and terminal send may modify terminal input. + From an active Dispatch, lifecycle send and ask default to that + Dispatch's owning Run mailbox. “Sent” means durably accepted—not pasted, observed, or + acted upon. +

+ +
+
+

run:run_123

+

The stable coordinator mailbox stored with that Run in the Orca runtime.

+
+
+

dispatch:dispatch_7

+

The exact supervised worker generation, independent of terminal handle changes.

+
+
+ + + +

+ Orca authenticates lifecycle reports automatically. The worker supplies only the Task + and Dispatch IDs injected in its preamble; it never supplies Run, runtime, host, + terminal, capability, or attestation IDs. At injection, Orca gives the managed pane a + narrow unforgeable Dispatch capability through its CLI bridge. The worker server + verifies that capability and its local pane; the Run home accepts the relayed report + only from the pinned paired peer for that Dispatch. Stop, abandon, or replacement + revokes it. Other reports remain stale history and cannot change Task state. This is + lifecycle integrity, not a general permission system. +

+ + + +
+
+

One Run home

+

+ The coordinator's server stores the authoritative Run, tasks, inbox ordering, and + acknowledgments. Worker servers do not replicate the Run database or elect a new + home. +

+
+
+

Remote mail waits safely

+

+ A worker server durably retains messages for its remote Dispatch until the Run + home imports and acknowledges them. Replies wait at the home until the worker + server reconnects. This is a narrow relay queue, not a replicated global inbox. +

+
+
+ +
+

Ordering and sizeFIFO by mailbox sequence, bounded to 50 messages per delivery.
Outstanding batch + One per mailbox. Until acknowledged, return the same Delivery ID and batch; + newer mail waits behind it. +
Acknowledgment + Whole-batch and idempotent. Repeating an acknowledged Delivery ID returns the + recorded result and does not consume newer mail. A Delivery is bound to the + consumer generation that received it; a fenced coordinator gets + consumer_fenced and cannot consume the replacement's mail. The same + current-consumer check applies to coordinator replies and other mailbox + mutations. +
Waiters + One active actionable waiter per mailbox. A second returns + waiter_exists; it never races to consume the batch. +
Crash safety + Receiving a batch never marks it consumed. Unacknowledged mail survives client, + mailbox-consumer, and runtime restart. +
Atomic continuation + check --ack delivery_81 --wait commits ack, checks queued mail, + then registers the waiter as one runtime operation. +
+

+
+

History modes do not consume

+

+
+

Timeouts are typed checkpoints

+ Wait returns timedOut, cancelled, or + connectionLost distinctly. None means worker failure, none consumes + mail, and transport keepalive output is not a worker heartbeat. +

+
+ +

+ Inbox acknowledgment confirms recipient consumption only. Lifecycle reconciliation + happens once, atomically, when the Run home imports an authenticated message. Every + terminal Dispatch transition is a home-side transactional compare-and-set: the first + committed completion, stop fence, or abandon wins; later conflicting input is retained + only as stale history. +

+ +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Question stateAsk/reply behavior
pending + ask from an active Dispatch defaults to its owning Run mailbox. The + first reply from the current authenticated Run consumer generation records the + answer at the Run home, relays it to the exact worker server, and wakes the + local asking call. +
answered + The pending ask or an explicit resume by the original Dispatch + returns the recorded answer. Repeating the same reply is harmless; a later + different answer conflicts. +
Wait timed out or client disconnected + Return the original question message ID and an exact + ask --resume msg_question_7 command without closing or duplicating + the question. Resume is allowed only for the original Dispatch. There is no + separate Question ID or durable expiry/deadline state machine. +
Acceptance response was lost + Retry the identical ask with its returned transport retry receipt + to recover the original message ID. A changed question conflicts; a blind new + ask is never the recovery path. +
Dispatch stopped or abandoned + The Run home atomically closes its pending questions, wakes local or resumed + waits with dispatch_inactive, and rejects later replies. +
+
+ + + +

# Worker: target defaults to the owning Run mailbox.

+ Blocking is a coordinator decision. The runtime must make waiting race-free, but it + must not decide that the agent has exhausted all parallelizable work. +

+
+ +
+
+

Worker observation

+

Read a supervised worker by Dispatch, regardless of server.

+

+ worker-read --dispatch resolves the worker server and exact process from + the Dispatch receipt. Its default auto source returns the exact + hook-reported Codex, Claude, OpenClaude, or Grok transcript when Orca can prove that + association; + otherwise it returns bounded, explicitly labeled terminal output. Agents never + choose a server, provider session ID, or transcript path, and task authority never + comes from transcript prose. +

+
+ +
+
+

Default path

+

Automatic exact selection

+

+ --source auto uses a proven supported transcript and falls back to + the existing bounded terminal reader with a typed reason such as + session_not_reported or + remote_capability_unavailable. +

+
+
+

Explicit policy

+

Transcript or terminal

+

+ --source transcript requires exact structured output and returns a + typed error rather than falling back. --source terminal always uses + the retained terminal snapshot. +

+
+
+ +
orca orchestration worker-read --dispatch dispatch_7 --source auto --limit 100 --json
+
+# Exact transcript result for a worker on the saved environment named windows

+  --cursor opaque-next-cursor --limit 100 --json
+ +
+
+

Source-pinned continuation

+

+ The returned cursor pins the Dispatch, process, source kind, and opaque source + identity. auto selects only on the first page. If the process or + provider session changes, Orca returns + worker_identity_changed or source_changed. +

+
+
+

Narrow provider readers

+

+ Structured reading reuses the existing bounded native transcript decoders only + for exact Codex, Claude, OpenClaude, and Grok associations. Other providers and + mixed-version peers retain terminal fallback; no resume, live-stream control, or + universal transcript framework is added. +

+
+
+ +

+ Every response labels source, sourceIdentity, + cursor, status, fallback reason, and bounded warnings. Terminal fallback + preserves the existing terminal fields and accepts legacy numeric cursors; new cursors + are opaque and never expose a transcript path. The worker-owning server performs the + read, and neither local nor federated selection may guess “latest session in this + directory.” +

Implementation appendix · agents may skip this section

+

Hidden guarantees for one Run home and many worker servers.

+

+ A coordinator on one Orca server must be able to supervise workers on another—for + example, a Run on a Mac with Dispatches on both that Mac and a connected Windows + server. The minimum federation contract routes commands and durably relays messages; + it does not replicate the Run or add scheduling policy. +

+
+ +

+ Agent rule: choose a remote worker once with --on. After that, keep the + Dispatch ID and follow the returned inspection commands. Reuse + mutation.requestId only to recover the same request after a lost response. + Peer identity, sequencing, capabilities, and relay acknowledgments below are Orca + implementation details—not fields agents choose or copy. +

+ +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Internal factV1 contractWhat agents see
Run home + The server where run-create executes owns the only authoritative + Run database: tasks, Dispatch state, inbox order, dedupe receipts, and consumer + generation. + The terminal binding routes ordinary commands home; no Run-home ID is typed.
Connected environment + The Run home stores its existing saved environment ID/name and authenticated + pairing for each worker server. Each Dispatch pins the authenticated peer + fingerprint captured at attachment, so re-pairing the saved environment to a + different server cannot retarget existing work. That relationship survives the + same remote server process restarting; the observed runtimeId + remains only an epoch. + --on windows when placement is explicit; receipts echo the name.
Remote Dispatch attachment + Before prompt injection, the worker server persists a verifier for the opaque + Dispatch capability, pinned Run-home peer identity, stable local pane and + process incarnation, effect receipts, and relay cursors. Credential material + is stored through current-user protected storage, not plaintext in a general + Run row. The worker server does not receive a copy of the Run DAG. + Nothing extra; the worker receives only Task and Dispatch IDs.
Caller pane + Each server's native, WSL, or SSH CLI bridge attaches the minted Dispatch + capability outside user parameters. The worker server verifies capability, + pane, and process incarnation; the Run home verifies the pinned authenticated + peer and Dispatch on relay import. + Orca authenticates lifecycle reports automatically.
+
+ +
+
+

Home-bound coordination

+

+ run-use/current, Task changes, check/ack, and replies go to the Run + home. Workers never choose or mutate the home, and there is no automatic home + failover. +

+
+
+

Server-owned resources

+

+ The selected worker server owns its worktree, terminal, process, and any nested + native/WSL/SSH/relay host. The Run home stores opaque receipts and routes show, + read, stop, and retry back to that owner. +

+
+
+

Durable relay, not replication

+

+ Worker-to-home lifecycle mail and home-to-worker replies remain queued at their + source until the destination imports and acknowledges them. Each item has a stable + ID, so reconnects are at-least-once on the wire and once in each inbox. +

+
+
+

Home-initiated connection

+

+ The Run home uses the same saved, authenticated environment connection already + used for remote RPC. It subscribes or pulls by cursor; the Windows server does not + need a separate pairing back to the Mac or a publicly reachable callback. +

+
+
+

Dispatch generations

+

+ Replacing a worker creates a new Dispatch ID; that ID is the generation. A report + from an older Dispatch or different pane remains history and cannot change current + Task state. There is no second agent-visible generation number. +

+
+
+

Idempotent control operations

+

+ Before effects, both home and worker server durably record authenticated peer, + request ID, canonical payload hash, operation state, and receipt. Identical + concurrent or later attempts join or return that record; a changed payload returns + request_mismatch. Receipts expose the opaque retry ID needed after an + unknown outcome. +

+
+
+

Typed unknown outcome

+

+ If a remote effect may have happened but Orca cannot prove it, return one + outcome_unknown shape with stage, mutation request ID, durable + effects/residuals, and exact inspection commands. +

+
+
+

Stop and replace

+

+ Stop first commits one home-side compare-and-set that fences new lifecycle changes, + blocks the Task, and closes pending questions, then best-effort stops only the + supervised agent process/terminal. If completion already won, stop returns + already_settled; if stop won, later completion is stale history. Orca + never deletes the worktree, setup output, or unrelated configured tabs. +

+
+
+ + + +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Federated relay ruleExact contract
Worker send acceptance + Success means the worker server durably stored the authenticated message in + that Dispatch's outbound relay. The worker may finish even while the Run home + is offline. +
Home import and lifecycle + The Run home stores the message and applies any valid lifecycle transition in + one transaction before acknowledging it to the worker server. Until import, + the authoritative Task honestly remains dispatched. +
Replies and control mail + The Run home durably queues them for the exact remote Dispatch; the worker + server stores them before acknowledging the home and waking a local waiter. +
Ordering and duplicates + Each direction uses a scoped key of pinned peer, Dispatch ID, direction, and a + monotonic source sequence, plus a 128-bit-or-stronger message ID. A receiver + imports only the next contiguous sequence, buffers gaps, and acknowledges only + the highest contiguous commit. The home assigns normal inbox order at import, + without pretending simultaneous servers have a global clock. +
Bounded storage + Enforce per-message byte limits and per-Dispatch pending item/byte quotas, + coalesce heartbeats, and reserve space for one terminal lifecycle report. A + full relay returns relay_quota_exceeded; V1 adds no dead-letter or + retention workflow. +
+
+ +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Remote edgeV1 behavior
Worker server unavailable before send + Return remote_runtime_unavailable before creating a Dispatch or any + remote effect. No remote Dispatch attachment exists, so the caller may retry + normally after reconnecting. +
Connection lost after send + Return outcome_unknown, mutation.requestId, last durable + stage, and exact inspection commands. Repeating the request ID returns the + worker server's original receipt or accepts it once; it never duplicates an + effect. +
Run-home restart + Run state, dedupe receipts, and unacknowledged mail survive. The process runtime + ID is only an epoch. Reconnect resumes relay cursors for every active remote + Dispatch; if the coordinator pane cannot be safely reminted, + run-use explicitly rebinds it. +
Saved environment re-paired or removed + If its authenticated peer fingerprint differs from the Dispatch attachment, + return peer_changed with no effect; never adopt the replacement + server. Removing an environment with a nonterminal Dispatch retains a routing + tombstone for inspection and abandon rather than erasing ownership evidence. +
Servers disconnected after start + The worker may continue. Its server retains lifecycle mail and questions while + replies remain queued at the home. Silence is not failure, no worker is + automatically replaced, and other servers continue delivering normally. +
Worker-server restart + Remote Dispatch attachments, effect receipts, and unacknowledged relay items + survive. The process runtime ID may change; the Run home routes by its saved + environment relationship and pinned peer. worker-show reports + running only when the stable pane and process incarnation match; it never + adopts a same-looking pane or newly launched process. +
Mixed server versions + Before effects, both servers must advertise one aggregate + orchestrationFederationV1 contract. Missing support returns + capability_unsupported; + it never silently degrades to prompt injection, terminal scraping, or + consume-on-read mail. The worker-side mutation revalidates the pinned peer and + advertised protocol recorded for the operation, closing the probe-to-effect + race. +
Structured worker output + The worker-owning server reads an exact hook-reported Codex, Claude, + OpenClaude, or Grok transcript when supported. If the additive federated read + method is absent, auto returns bounded terminal output labeled with + remote_capability_unavailable; + transcript returns transcript_required. +
+
+ +

+ Capability checks cover only the new federation contracts, not every platform or host + feature. Existing worktree, setup, terminal, Git, WSL, SSH, and relay primitives keep + their proven compatibility behavior; optional, truthfully labeled observation may + degrade. +

+ + + +
+ + + + + + + + + + + + + + + + + + + + + + + + + +
MechanismWhy it staysWhy it is not a scheduler
Server ownershipPrevents commands from acting on a same-looking resource on the wrong host.The agent chooses --on; the owner only determines routing.
Dispatch identityPrevents stale workers from overwriting current task state.It does not retry, replace, or start anything automatically.
Unknown outcomePrevents duplicate remote effects after a disconnect. + The receipt gives last durable stage and inspection command; the coordinator + chooses inspect, reconcile, retry, or abandon. +
+
+ +

+ Safety may reject stale, wrong-pane, or wrong-server control-plane mutations. It does + not police worker filesystem access, invent new work, choose a worker, or decide that + waiting is the coordinator's best next action. +

+ + +
+ +
+
+

Agent ergonomics

+

The skill should be a cookbook, not a second help page.

+

+ orca --help already owns syntax and exhaustive flags. The skill should + teach judgment: which topology to choose, how to preserve parallelism, what the + command returns, and what not to create afterward. +

+
+ +
+
+

Parallel fan-out

+

Start every independent task first. Only then call check --wait.

+
+
+

Shared-worktree review

+

Use the current worktree when sharing its exact state is useful.

+
+
+

Independent writers

+

Create separate worktrees when a concrete checkout conflict calls for isolation.

+
+
+

Ask and reply

+

Use a threaded question; continue other work while only that worker is blocked.

+
+
+

Read a full-screen agent

+

Use worker-read --dispatch; Orca routes to the owning server.

+
+
+

Replace safely

+

Inspect the stop result before deciding where to start a replacement.

+
+
+ +
+
+

Move out of the skill

+
    +
  • Complete command and flag catalogs
  • +
  • Internal database and delivery terminology
  • +
  • Provider-specific internals before the common path

+ Current Orca · parallel workers in the current worktree +

+

+ A Run-home restart preserves the Run, retry receipts, and the same unacknowledged + Delivery; run-use is needed only when Orca cannot safely remint the + previous coordinator pane.

+# running/ready → keep waiting; gone/failed → explicit retry-of; unknown → inspect or stop/abandon.
+
+
+ +

+ The skill must say that check --wait returns a batch. Process every message + before acknowledging it. +

+ +
+

Scenario tests matter more than keyword checks

+
+
    +
  • Reuse the terminal returned by worktree creation.
  • +
  • Start three independent workers before waiting.
  • +
  • Omit runId only when the coordinator terminal is explicitly bound.
  • +
  • Use current-worktree collaborators without unnecessary worktrees.
  • +
  • Fence an old consumer's acknowledgment after run-use rebinds.
  • +
  • Import duplicated and out-of-order relay frames only in contiguous order.
  • +
+
    +
  • Never treat a worker report as verified integration.
  • +
  • Never replay terminal input after unknown acceptance.
  • +
  • Page terminal output by Dispatch; use a session source only when exact.
  • +
  • Inspect an ambiguous remote stop before choosing the next action.
  • +
  • Let the first committed stop/completion transition win transactionally.
  • +
  • Reject a re-paired peer and never adopt a same-looking restarted process.
  • +
+
+

+

Complexity audit

+

Keep only the machinery required by Orca's concrete failure modes.

+

+ Every retained primitive below addresses a failure Orca can reproduce today. Broader + policy and product layers remain out of scope until a simpler primitive proves + insufficient in real use. +

+
+ +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Observed Orca needKeepDeliberately defer
Lifecycle messages can be lost, injected into prompts, or consumed before a caller receives them.Durable typed mail, explicit acknowledgment, and race-free blocking waits.Dead-letter workflows, priority schedulers, watchdog policy, or a second queue product.
Terminal scrollback is not always the best available source, but session identity can be ambiguous.Terminal output as the baseline and an optional exact, source-pinned adapter.A universal session ontology, resume layer, or global provider exclusivity.
Remote acceptance, process exit, and worker claims provide different levels of evidence.Explicit lifecycle, fenced replacement, and typed unknown-outcome handling.Automatic retry, inferred success, rollback, or generalized recovery policy.
A Run home must coordinate workers across restarts and connected Orca servers.Stable Run, Task, and Dispatch identity with authenticated server relay.Role simulation, worker scoring, organization models, or integration queues.
+
+ +
+
+

Tests prove the contract

+

+ Scenario tests must demonstrate durable messages, authenticated relay, lifecycle + fencing, and truthful recovery. Design analogy is never a substitute for an + Orca-local executable contract. +

+
+
+

Complexity requires local evidence

+

+ A generalized scheduler, fairness policy, dead-letter workflow, or integration + system should be proposed only after Orca users demonstrate that the simpler + primitives cannot solve a recurring problem. +

+
+
+ + +
+ +
+
+

Implementation order

+

Each phase should remove one concrete source of agent confusion.

+

+ There is no UI phase. Each runtime change ships with a version-matched example and a + misuse test so the skill and behavior cannot drift apart. +

+
+ +
+
+
Phase 0
+
+

Rewrite the orchestration skill as recipes

+

+ Teach correct fan-out, current versus new worktree selection, startup terminal + reuse, --setup run for new worktrees unless the agent states a + concrete reason to skip or inherit, while preserving the existing + start-immediately default, current batch behavior, and blocking only + after useful parallel work is exhausted. Correct the one-message claim and + document today's delivery limits. + Rename or remove the existing scheduler-like orchestration run --spec + command before the lightweight run-* vocabulary can ship. +

+
+
+
+
Phase 1
+
+

Run mailbox, truthful completion, and crash-safe consumption

+

+ Add explicit Run-home binding, stable logical recipients, strict + inbox-only structured mail, succeeded/failed worker outcomes, one outstanding + FIFO batch, explicit acknowledgment, typed timeout results, ask/reply state, + a narrow runtime-minted Dispatch capability carried by the CLI bridge, and + resume-by-message-ID after a disconnected ask. Migrate existing global rows to + one unbound inspect-only legacy Run; do not infer bindings. Do not add separate + Question IDs or expiry policy. +

+
+
+
+
Phase 2
+
+

Local synchronous worker start and control

+

+ On the Run home, compose existing worktree, setup, terminal, and dispatch + primitives with setup-run as the new-worktree default, a durable request/stage + receipt, side-by-side setup/agent startup by default, startup-terminal reuse, + exact readiness, and Dispatch-routed + show/read/stop/abandon. Prove current, existing, + child, top-level, failure, restart, and unknown-outcome behavior before adding a + network boundary. Do not add a background provisioning executor. +

+
+
+
+
Phase 3
+
+

Connected-server Dispatch and relay

+

+ Extend the same primitives with saved-environment placement, pinned peer identity, + remote Dispatch attachments, paired-server calls, and bounded bidirectional relay + with contiguous cursors and idempotent acknowledgment. Validate Mac-home/Windows- + worker and Windows-home/Mac-worker completion, question/reply, read, stop, + either-side restart, re-pairing, disconnect, and mixed versions—without Run + replication, failover, or scheduling. +

+
+
+
+
Phase 4
+
+

Exact structured worker output

+

+ Reuse Orca's existing pane-scoped hook association and bounded + Codex/Claude/OpenClaude/Grok transcript decoders. Add + auto|transcript|terminal selection, + path-free source identity, opaque source-pinned paging, and labeled terminal + fallback without adding provider control or a universal transcript layer. +

+
+
+
+ +
+
+

Success looks like

+
    +
  • Agents start all independent work before waiting.
  • +
  • Lifecycle messages never flood editable coordinator input.
  • +
  • One Run can supervise Mac and Windows workers through one home inbox.
  • +
  • Remote completion and replies survive either server temporarily disconnecting.
  • +
  • No delivery is consumed before explicit acknowledgment.
  • +
  • Failed worker reports set failed—not completed—and remain worker assertions.
  • +
  • Worker start never reports a resource created before it exists.
  • +
  • Full-screen agent output remains readable when an adapter supports it.
  • +
  • Stale, wrong-pane, or wrong-server workers cannot mutate current task state.
  • +
+
+
+

Complexity budget

+
    +
  • No new concept without a common recipe that needs it.
  • +
  • No automatic action whose trigger an agent cannot explain.
  • +
  • No provider field that an adapter cannot actually observe.
  • +
  • No hidden default omitted from the operation receipt.
  • +
  • No control-plane fact derived from untrusted transcript prose.
  • +
  • No future feature included merely to keep the architecture open-ended.
  • +
+
+
+
+ +
+
+

Explicit boundaries

+

What this proposal intentionally does not build.

+

+ These are not hidden later phases. They require separate evidence and a separate + proposal if Orca eventually needs them. +

+
+ +
+
+

No product UI

+
    +
  • No dashboard or run/task view
  • +
  • No global inbox, badges, or queue screen
  • +
  • No coordinator chat surface
  • +
  • No task DAG visualization
  • +
  • No changes to existing Orca UI behavior
  • +
+
+
+

No scheduler

+
    +
  • No automatic task dispatch or placement
  • +
  • No capacity vectors or resource classes
  • +
  • No fairness, priority aging, or global queue
  • +
  • No pause, resume, or drain controls
  • +
  • No automatic retry based on silence
  • +
+
+
+

No integration subsystem

+
    +
  • No commit or branch tracking
  • +
  • No automatic merge or landing
  • +
  • No target-ref locking
  • +
  • No independent verification of worker claims
  • +
  • No cross-run work lineage model
  • +
+
+
+

No speculative framework

+
    +
  • No organization charts, roles, or worker profiles
  • +
  • No universal provider transcript schema
  • +
  • No dead-letter or poison-message workflow
  • +
  • No generalized continuation/checkpoint protocol
  • +
  • No project hierarchy above lightweight runs
  • +
  • No replicated Run database, leader election, or automatic home failover
  • +
+
+
+ +
+ Could Orca add these things later? +
+ Yes, but strong primitives do not need speculative abstractions for them today. A + future feature should compose the same start, message, wait, read, stop, identity, + and ownership contracts. It should justify its own concepts from observed Orca use. +
+
+ +
+ Does removing commit tracking make worker results less trustworthy? +
+ It makes the contract more honest. Today Orca verifies who is authorized to report a + result, not that every claim inside the result is true. A coordinator may explicitly + ask another worker to review or run validation. That is agent-directed orchestration, + not an implicit integration subsystem. +
+
+ +
+ What about connecting multiple Orca runtime servers? +
+ It is a core requirement. A Run stays authoritative on one home server while remote + Dispatches execute on saved connected environments such as a Windows machine. + Authenticated routing plus a small durable relay carries lifecycle mail and replies + across disconnects. This intentionally stops short of a global cluster: no Run + replication, leader election, automatic failover, distributed scheduler, or lease + manager is required. +

The first ordinary flush waits 8 ms, a + sustained flush continues after 1 ms, and interactive or transformed output + may publish immediately; a turn publishes at most two 16 Ki-unit chunks. +2. `RelayDispatcher.notify('pty.data')` broadcasts each publication. The + ordinary notification path ignores `process.stdout.write()` and + `Socket.write()` returning `false`, so every later frame can extend a Node + writable queue after the first saturated write. +3. Main's `FrameDecoder.feed()` drains all complete frames synchronously. + `MultiplexerTransport` exposes neither read pause/resume nor write drain. +4. `SshRelaySession.wireUpPtyEvents` is the production SSH delivery owner. It + calls `runtime.onPtyData()` and then sends `pty:data` directly to the + renderer. It does not enter the `PtyPendingDataDrainQueue` installed by + `src/main/ipc/pty.ts` for local and daemon providers. +5. Main therefore has no SSH queue record against which to calculate useful + upstream progress. The current cumulative renderer ACK is converted to a + delta, the SSH path commonly emits zero, and the relay's + `PtyHandler` ignores `pty.ackData` in any case. +6. Production POSIX and Windows deployment launches the relay detached, then + attaches the real desktop bridge through a Unix socket or named pipe. + Dispatcher construction therefore cannot identify the usable session owner. +7. `OrcaRuntime.onPtyData` returns synchronously while headless-emulator writes + append captured strings to an unmetered asynchronous `writeChain`. +8. Relay fs/Git chunks use `notifyBulk`/producer chains outside any stated PTY + reserve; they can occupy the same ordered sink ahead of cancel, ACK, and + interactive output. +9. `computeRemoteRelayDir` content-hash-scopes both daemon files and endpoints. + Mixed deployed binaries are fenced, while a prior-version daemon can remain + alive in its old directory after upgrade. +10. `SshPtyProvider` omits the existing producer-pause hooks, and production + constructs `MultiplexerTransport` in both SSH sentinel handling and the WSL + hook path. +11. Lossless remote terminal streams ACK encoded byte deltas today and retain + only aggregate in-flight bytes; no existing record maps those bytes back to + immutable SSH source intervals. `694363805` extracted their UTF-16 + code-unit-preserving chunker to + `src/main/runtime/rpc/terminal-output-frame-chunks.ts`; it improves + performance and equivalence coverage but adds no provider/token identity. +12. `1fd0f731f` routes SSH folder-workspace automation launches to their owning + host. It does not change PTY output delivery or make folder workspaces Git + worktrees. +13. `077561f89` moved remote terminal stream UTF-8 measurement into + `terminal-stream-byte-length.ts`, preserving legacy flush boundaries and + partial over-limit counts. Those encoded-byte counters remain transport + budgets, not SSH source credit. +14. `2dac0741b` preserves ordered DEC mode 2031 subscribe/withdraw decisions + when the current main pending-data queue drops or salvages renderer output. + Its bounded cross-chunk scan state is projection metadata that a unified + SSH intake must preserve; it does not settle source spans. +15. `d547e278f` adds epoch-scoped, post-delivery watermarks for mobile + notification catch-up. That notification replay protocol is distinct from + mobile terminal streaming; its sequence and epoch cannot identify or settle + PTY source ranges. + +This project first moves ownership of every SSH provider data event out of the +direct `wireUpPtyEvents` send and into one main delivery intake. That intake +performs runtime ingestion, desktop delivery policy, remote-consumer +fan-out, and upstream span settlement exactly once. Adding another listener is +forbidden because it would double-ingest and double-render output. + +The initial 8 ms/continuation 1 ms cadence and two-write limit are scheduling +controls, not bounds. A continuous producer can currently grow the relay +writable queue, SSH buffers, decoder input, and Electron heap. The frame-header +`ack` remains transport liveness bookkeeping; it is not PTY credit and never +enters this ledger. + +The falsifiable invariant is: accepted SSH relay PTY output remains bounded +across relay writable queues, SSH/socket transport, main decoding and model +admission, renderer projection, and remote consumers while every source span +settles exactly once in order. The observable failure on this baseline is that +ordinary relay PTY notifications continue after `write(false)`, main drains all +complete frames synchronously, SSH bypasses `PtyPendingDataDrainQueue`, and +headless emulator writes enter an unmetered Promise chain. A sustained SSH +producer can therefore increase relay, transport, and main memory without a +finite upstream credit owner. + +Authority and delivery boundaries on this baseline are: + +```text +renderer/viewer + -> IPC or runtime RPC + -> Electron main / OrcaRuntime + -> SshRelaySession + SshPtyProvider + -> SshChannelMultiplexer + -> SSH channel / --connect bridge + -> RelayDispatcher + -> PtyHandler + -> node-pty / ConPTY +``` + +`PtyHandler` owns native output and replay; relay dispatcher/adapters own +client writes; `SshRelaySession.wireUpPtyEvents` owns production SSH ingestion; +`OrcaRuntime` owns the headless model; `src/main/ipc/pty.ts` owns +main-to-renderer accounting; and `terminal.multiplex` owns remote-consumer +delivery. The current bug is fragmentation across those owners, not a missing +renderer-only cap. + +## Required invariants + +1. Protocol credit uses one canonical unit: UTF-16 code units in the + pre-transform source span, called source units (`su`). Retained memory and + wire queues use exact bytes and never masquerade as source credit. +2. For a negotiated token, + `0 <= sentEnd - creditedEnd <= windowSu`; each admitted slice fits the + remaining window, so no frame overshoot is permitted. ACKs are cumulative, + monotonic, client/PTY/token scoped, and never exceed `sentEnd`. +3. Source-credit spans are immutable and stored in a cumulative ledger. + Queue data may merge, split, salvage, thin, or coalesce without moving, + copying, or destroying ledger boundaries. +4. A sink `write(false)` accepts its frame exactly once. No ordinary frame is + written again before drain. PTY admission stops before a reserved + control/liveness capacity is consumed. +5. A spawn/attach token remains `activating` until its metadata-only response + crosses the relay sink fence. Main may receive source frames after its + synchronous provisional install, but they remain lease-private and cannot + project. A validated reconnect contract transfers that lease into the + attempt's private recovery quarantine; final commit, model, and desktop + admission remain fenced until all recovery `pty.data` and the exact + completion fence agree. +6. Data is ordered within a token. `pty.exit` follows every accepted data frame + and cannot bypass the sink gate or activation fence. Publishing exit seals + new data but does not retire an uncredited suffix. +7. Every open token-owned span and consumer obligation ends exactly once in + `settled`, `transferred`, or `canceled`; a transfer may pass through the + non-terminal `transferring` state only while its named replacement fence is + outstanding. A canceled `restoreRequired` delivery remains addressable until + its exact response settles and retires only if the map still names that + record. Records are never merely abandoned while their relay token can live. +8. Desktop, mobile, web, and agent-session consumers follow the explicit + settlement policy below. A stalled recoverable desktop projection cannot + freeze a healthy lossless remote view. +9. One slow additional subscriber cannot retain unbounded data or stop a + healthy subscriber. The negotiated session owner is not torn down for one + PTY's backlog; constructor position never grants that role. +10. When every delivery for a PTY is blocked, pause the native PTY. Resume only + when both local and relay-wide low-water predicates hold. +11. An unexpected client loss transfers outstanding output to a bounded + reconnect-grace owner. Normal subscriber absence retains only the existing + replay tail and no live queue. +12. Decoder work, decoded bytes, model admission, and activation-hold turns are + bounded. A self-imposed read or local-write pause rebases both liveness + clocks. Main-to-relay drain reselects liveness, then control, ahead of + ordinary PTY input; four consecutive control selections force one ordinary + selection when both lanes remain non-empty. +13. Disconnect, provider replacement, renderer reload, exit, disposal, and + workspace removal have explicit bounded cleanup. After their required + publication, transfer, cancellation, or generation-close proof, they leave + no open span, token, writer callback, drain waiter, timer, cursor, or paused + PTY. Recovery-cancellation publication failure or rejected proof fails + closed by closing only the owning provider generation and disposing its + mux, provider, publishers, transferred activation state, and registration + once. +14. All counters are finite safe integers. A transformed frame requires a + valid `rawLength`; malformed, excessive, stale, and cross-client values + cannot create credit or crash either process. +15. The session owner is elected by an authenticated session grant and + identified by an owner generation. It is never inferred from dispatcher + construction, stdout, socket order, a path, `.git`, or a worktree. +16. Recovery and serialization control responses contain metadata only. + Source-ranged recovery or snapshot bodies use bounded producer lanes and + explicit completion fences before live delivery. +17. The required main model has bounded asynchronous admission. Relay credit + cannot advance while data waits outside that charged admission or after an + emulator failure. +18. Negotiated V1 has one upstream ACK owner. Renderer projection progress and + remote encoded-byte ACKs settle ledger obligations but never emit legacy + SSH ACK deltas. +19. Required obligations becoming terminal, cumulative ACK queueing, and ACK + publication are three monotonic states. A write callback publishes already + eligible credit; it never creates eligibility. +20. Desktop admission carries immutable span identity through model reserve, + projection queue, renderer send, ACK, salvage, reload, and replacement. + Failure either rolls back an uncommitted transaction or transfers a + committed obligation with proof. Exit timeout acquires cancellation proof + without mutation, transfers published projections, commits proof + reclamation, prepares/finalizes exit once, and rechecks the provider + generation before each post-proof mutation. +21. Projection drop, thinning, salvage, restore, and replay preserve current + main's ordered terminal side-effect facts and bounded scanner state, + including DEC mode 2031 subscribe/withdraw decisions. Pre-commit rollback + restores the prior scanner snapshot, committed transfer moves projection + state exactly once, and an explicit source gap resets cross-chunk state; + none of these facts creates source credit. +22. The immutable delivery identity is exactly `(id, providerGeneration, +clientGeneration, ownerGeneration, ptyIncarnation, deliveryToken)`. Each + admitted source span additionally fixes `spanId`, source/display half-open + ranges, transform metadata, and model-sequence end where required. +23. Receive activation begins at `checkpointSourceEndSu`. Every recovery + `pty.data` frame is contiguous from that cursor through `recoveryEndSu`; + only the exact `pty.recoveryComplete` writer settlement opens live output. +24. A reentrant cumulative ACK may reserve only the exact pending send + boundary for the same delivery identity. Failed send settlement retains + that boundary and permits only an exact same-token retry. +25. A fixed `fs.streamChunk` keeps the protocol's 256 KiB payload and offset + semantics. It may use the fixed-frame lane only from an empty, + unsaturated producer epoch; ordinary PTY and reshapable bulk frames still + obey the non-reserved capacity. +26. A lossless remote stream may advance its cumulative encoded-byte ACK to an + interior byte offset. Exact byte budget is released immediately, while the + covering immutable source frame remains unsettled until its complete + encoded boundary is crossed. +27. A lossless remote stream accepts an in-place source-token rotation only + when PTY ID, provider generation, and incarnation match; both client and + owner generations strictly increase; the token changes; and source/display + coordinates remain contiguous. Old or partially increasing identities are + rejected. +28. Snapshot replacement commits are idempotent and never synthesize byte or + source credit. Duplicate/closed ledger commits are no-ops; if cancellation + proof already reclaimed a reserved span, source replacement commit rejects, + rollback skips the absent span, and settle/detach prune cached mappings. +29. Exact exit seals a provisional or private-recovery receive lease before + any later same-token frame can reserve or project. Exit publication waits + for the held contiguous prefix to admit or for cancellation proof whose + sent end covers every privately observed exact-token frame. +30. Transfer does not consume rollback authority until the ledger proves the + lease is still current and installs the private recovery sink. A stale + transfer can still retire and cancel only its own token. +31. Canceled-frame suppression retains at most one latest ordered delivery + identity per relay PTY. Transport ordering makes earlier token records + obsolete when a later cancellation is observed; exact next activation, + PTY exit, or provider teardown clears the remaining record. + +## Protocol + +### Architecture decision record + +Decision: `PtyConsumerSession` is a shared semantic state machine, not a +universal transport protocol. The architecture gate is closed and is no +longer waiting for exact wire/API names: the SSH adapter implements +`sourceActivation`, source-bearing `pty.data`, `pty.recoveryComplete`, +cumulative `pty.ackData`, and token-scoped cancellation. Current-working-tree +deterministic validation is an engineering gate; unexecuted live topologies +remain separate promotion gates. A relay-only +`pty.getCapabilities` followed by `pty.negotiateClient` remains rejected +because it would create a second readiness authority beside the existing +authenticated handshakes. + +The 2026-07-28 architecture/terminal review closed its three blocking +findings as follows: + +| Finding | Implemented resolution | +| ------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | +| Exited delivery removed while uncredited spans remain | Native exit seals the token; logical state survives until cumulative ACK, exact transfer, token-scoped cancellation proof, or generation close. | +| Terminal obligations depended circularly on ACK publication | Obligation terminality advances `obligationsTerminalEndSu`; the coalescer independently queues `ackQueuedEndSu`; only mux write settlement advances `ackPublishedEndSu`. | +| Desktop projection admission lacked immutable range identity and rollback | Model, source span, projection range, and scanner snapshot reserve atomically; pre-commit failure rolls back, while post-commit replacement transfers with proof. | + +Later adversarial review also required exact recovery continuity, stale-attempt +isolation, session-grant fallback semantics, and idempotent remote detach +after token reclamation. Those are incorporated in the activation, lifecycle, +cleanup, tests, and compatibility sections below. + +The final 2026-07-28 architecture/terminal re-review found and closed three +additional interleavings: + +| Finding | Implemented resolution | +| --------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | +| Failed exit publication could discard a sealed delivery before its suffix was credited | Failed publication retains the sealed delivery; late cumulative ACK and exact owner recovery can still settle it, and exit is republished without reopening source admission. | +| Recovery-response cancellation authority ended at enqueue rather than writer settlement | The request remains cancellation-authoritative until its response settles; retry reuses the same provisional replacement identity instead of creating an unfenced owner. | +| Snapshot replacement transferred every pending remote span at one sequence fence | Each immutable span retains its model-sequence end; replacement transfers only spans covered by the authoritative `SnapshotEnd`, while trailing spans remain live and replay in order. | + +Current-working-tree adversarial reconciliation closed these additional integrated +failures without widening the approved topology: + +| Finding | Implemented resolution | +| ---------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | +| Invalid-checkpoint `restoreRequired` left a canceled delivery blocking retry | Keep the exact canceled record through response settlement, then delete it only if it is still current; retry mints a fresh activation token. | +| Recovery cancellation publication/proof rejection left ambiguous authority | Raise a typed recovery-cancellation failure and close the exact provider generation, disposing its mux, provider, publishers, lease, and registration exactly once. | +| Remote partial ACK or higher-generation token rotation detached the stream | Release exact cumulative byte credit at any valid interior offset without source settlement; admit only contiguous strictly higher client/owner generations with a new token. | +| Snapshot cleanup raced cancellation-proof reclamation | Make ledger replacement commit idempotent and make remote replacement commit reject reclaimed spans while rollback, settle, and detach prune them without dereference or new credit. | +| Drain resumed the main mux's old ordinary FIFO ahead of control | Select liveness, control, and ordinary from separate FIFO lanes; prioritize control after drain and force one ordinary write after four controls. | +| Same-turn source data escaped a provisional activation | Queue data privately under the provisional lease; commit publishes in order, while rollback drops it, restores only the active predecessor, and awaits exact cancellation proof. | +| Exit cancellation proof reclaimed spans before projection transfer | Acquire proof first, transfer projections, commit proof, prepare/finalize once, and fence every post-proof step against provider-generation close. | +| Exit during private recovery could publish before held frames settled | Seal the private lease immediately, wake the exact recovery fence, then either admit the ordered prefix before exit or retire it only after exact token-cancellation proof. | +| A superseded transfer lost its cancellation authority | Keep the outer lease unsettled until transfer ownership is verified; a stale transfer can still roll back and request cancellation for its exact token. | +| Recovery proof watermark skipped rejected or post-restore frames | Observe every exact-token private frame before retention or restore checks and reject any cancellation proof whose sent end is below that immutable high-water. | +| Canceled-token tombstones grew once per token | Retain only the latest ordered canceled token per relay PTY, replace it on later cancellation, and clear it at exact next-activation, PTY-exit, or provider-teardown boundaries. | +| Reconnect checkpoint raced a running raw model callback | Freeze the exact provider-generation/PTy admission, cancel only queued work, and await the bounded running callback before exporting a checkpoint. | +| Migration-owned callback failure closed the shared provider | Contain failure to the exact migrating PTY, reset only its model, preserve siblings and transport, and retain the ordinary generation-fatal policy outside migration. | +| Closed-generation telemetry omitted active gaps | Compact exact closed ranges and expose the count of allocated but unclosed provider generations below the closed high-water. | + +The final exact-implementation-head architecture/lifecycle review was clean +across 27 files and 296 tests. The transport/topology review confirmed the +exact-PTY containment fix and found no remaining code blocker; its sole +evidence finding was the stale artifact record replaced by the +provenance-bound build and Docker run above. + +The common state machine accepts only: + +- an authenticated principal and owner-eligibility decision from the adapter; +- a consumer generation and optional capability offer/grant; +- a subscription/delivery identity and close reason; +- an adapter-provided publication fence. + +It does not authenticate sockets, parse frames, own sentinel/residue bytes, +wait for stream drain, prove reconnect credentials, or define remote-runtime +encoded-byte ACKs. Those remain adapter responsibilities. The semantic input +and output may be represented as: + +```ts +type PtyConsumerSessionHello = { + clientInstanceId: string + requestedRole: 'session-owner' | 'subscriber' + resume?: { + ownerGeneration: number + ownerLease: string + } + capabilities?: { + outputFlowControl?: { versions: [1]; requestedWindowSu: number } + } +} + +type PtyConsumerSessionGrant = { + serverBuildId: string + clientGeneration: number + role: 'session-owner' | 'subscriber' + ownerGeneration?: number + ownerLease?: string + capabilities?: { + outputFlowControl?: { version: 1; windowSu: number } + } +} +``` + +These types are not wire schemas. Authentication produces a transport-bound +principal and `allowSessionOwner` before the state machine sees the offer. A +request field cannot self-promote a client. The state machine performs +generation allocation, owner replacement, capability intersection, +publication fencing, and close cleanup; the adapter proves identity, carries +the semantic fields, and calls the fence. + +The reviewed decision preserves the existing connection machinery: + +| Path | Authentication and identity | Binding in this PR | +| --------------------------------------- | ---------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------- | +| Local in-process provider | trusted main-process construction | unchanged; it does not negotiate SSH V1 | +| Local daemon | token-authenticated `HelloMessage`, stable `clientId`, paired control/stream sockets, and `daemonIdentity` | unchanged; an exact-version daemon remains outside the SSH wire contract | +| SSH relay socket/named pipe | existing authenticated relay endpoint and dispatcher client identity | first framed `pty.openClient`; response settlement is the readiness fence | +| Primary relay stdio and WSL child stdio | no authenticated dispatcher principal in this PR | bounded legacy transport only; an unproved client cannot become session owner | +| Remote-runtime server | paired-device/E2EE identity and connection ID | source-range reserve/commit/rollback only; never receives an SSH owner lease | + +The implemented owner path is the authenticated detached relay endpoint used +by the SSH provider. After extracting the exact sentinel and residue, main +sends `pty.openClient` before spawn, attach, or ordinary dispatch. The relay +adapter queues later decoded frames behind the session response's write +callback, so an eager next request cannot race activation. Main marks the +provider ready only after receiving the valid response. + +Detached `--connect` first reads the version-scoped endpoint credential and +authenticates its Unix-socket/named-pipe bridge before emitting its sentinel. +The adapter converts that proof into a principal and +`allowSessionOwner = true`; `pty.openClient` carries no secret to the generic +RPC handler. The primary relay stdin/stdout dispatcher identity remains +explicitly unproved and therefore subscriber-only; there is no launch nonce in +this implementation. WSL child stdio shares the bounded decoder/writer +transport changes but does not negotiate an SSH V1 owner in this PR. A manual +relay without the version-scoped endpoint credential is also subscriber-only. + +POSIX hosts may expose different shell and SFTP home namespaces. While the +install lock is held, a per-launch marker maps the canonical shell credential +path to the matching SFTP-relative path; the credential write uses that +mapping before the lock is released. If the marker is unavailable or its +creation fails with confirmed termination, main generates the credential +remotely with the selected Node binary at the canonical shell path. System SSH +keeps its shell-path writer, Windows keeps its native secure writer, and the +remote CLI launcher receives the same credential-file path. An unconfirmed +marker teardown retains the lock rather than authorizing a competing writer. + +The review compared sentinel extension and the single request against one +readiness authority, no first-spawn race, authenticated owner replacement, +response publication fencing, reconnect idempotency, exact residue transfer, +and deterministic testability. The single request wins for the authenticated +deployed-relay bridge. A separate capability probe, two-step negotiation, and +a generic cross-transport wire API are not approved. + +The local daemon adapter is deliberately not changed in this PR. Its existing +sequential control/stream hello, authentication, exact-version fencing, and +prior-version isolation remain authoritative. Reusing the semantic state +machine there is a later design decision and is not required to ship the SSH +bound. + +Every new SSH session offers V1, and every relay from the same build advertises +V1. The server intersects the offer with its supported versions and clamps +`windowSu`; an older client that omits the capability receives bounded legacy +delivery while still establishing the role and generation. Main accepts only +a returned version it offered and a finite safe integer satisfying +`0 < windowSu <= requestedWindowSu`. An absent or invalid V1 grant after +`pty.openClient` succeeds closes that connection attempt rather than silently +downgrading it. + +For compatibility with a legacy relay that does not implement +`pty.openClient`, main permits token-free bounded legacy delivery only for the +narrow same-build-validated JSON-RPC method-not-found result. Other errors, +missing grants after a successful method call, and unproved version skew fail +closed. This fallback does not change the normal same-build contract: the +session offers V1 and the relay advertises and grants it. + +“Bounded legacy” is transport backpressure, not a hidden source-credit mode. +It creates no delivery token, source window, or cumulative ACK obligation, and +the relay continues to ignore legacy `pty.ackData`. Slice 3 retains at most +2 MiB of ordinary publications per client and 32 MiB across the relay, with +1 MiB/24 MiB low waters, plus at most one 128 KiB producer-held frame per PTY. +At a cap, `PtyHandler` pauses the PTY; accepted write callbacks/drain remove +transport publications, and crossing both low waters resumes it. Slice 2/4 +read pauses propagate through SSH until the relay writer saturates, so stalled +model admission remains bounded without pretending renderer ACKs reached the +relay. + +Legacy exit waits only for preceding transport publications and the exit write +callback; main's receive-exit barrier below still waits for its admitted model +and projection work. Transport close cancels the connection's retained +publications and reconnect uses the existing replay/restore behavior. It may +pause all legacy subscribers behind one slow connection because legacy mode +has no authenticated source-owner role, but it neither drops output nor grows +without bound. These mechanics remain available to negotiated legacy peers. + +The session hello creates no PTY token. A later V1 spawn/attach returns a fresh +`deliveryToken` and creates a subscription only for the authenticated +transport client and installed generation. `pty.attach` must receive request +context just as `pty.spawn` does. Spawn failure, identity mismatch, stale +context, and response cancellation create no active V1 subscription. A legacy +spawn/attach returns the current identity/replay shape and creates only the +bounded transport subscription above—no token or source coordinate. A live V1 +token never rotates into legacy service; disconnect closes it before any +separately negotiated legacy fallback connection can open. + +Session ownership is granted by the authenticated session hello, not +constructor-assigned: + +- fresh relay deploy writes one endpoint credential beside the versioned + endpoint, reusing the local daemon's token-authenticated-hello pattern rather + than inventing a second claim protocol. It has mode `0600` on POSIX or a + current-user ACL on Windows. `--connect` proves it; a plain dispatcher socket + without the credential is subscriber-only. Primary relay stdio and WSL + child stdio remain unproved bounded-legacy transports. The adapter converts + proof into `allowSessionOwner = true` and does not expose the credential to + RPC handlers; +- the main creates one opaque `clientInstanceId` for its relay-session + lifetime. The first authenticated owner hello when no owner exists binds + that identity, returns a lease, and starts owner generation 1; +- until that first grant crosses its write fence, a retry with the same + authenticated identity is idempotent and any competing identity is rejected. + Once fenced, replacement requires both the current lease and expected + generation; +- an unexpected owner disconnect retains that lease and its PTY grace cursors + for 30 seconds. A reconnect presenting the lease and expected owner + generation atomically increments the generation, rotates the lease, replaces + the old client, and transfers grace ownership before any new token activates; +- a same-generation retry is idempotent only for the same live client. + Competing, stale, lease-less, or unauthenticated identities cannot replace + the owner and may connect only as ordinary subscribers; +- after grace expiry, the old owner lease is invalidated and the next + owner-authorized session hello can elect a new owner at the daemon's next + monotonic owner generation; generations are never reused. Ordinary + subscribers never inherit owner teardown protection merely by arriving first. + +Source activation, `pty.data`, recovery completion, ACK, and cancellation +carry client/owner generations and the delivery token. `pty.exit` retains its +existing PTY ID plus incarnation shape and resolves against the already +installed delivery identity; it cannot create or rotate one. Main rejects a +generation other than the one installed by its synchronous response hook. The +constructor stdout client is never implicitly a session owner. Production +launches detach on POSIX and Windows, invalidate stdout, and connect the +desktop bridge through `attachClient` over the versioned Unix socket or named +pipe. Unproved direct stdio remains subscriber-only. + +Capability support is negotiated on every SSH session. `SshRelaySession` +always offers V1 during initial connection and automatic reconnect, and POSIX +and Windows relays always advertise it as an unconditional capability. Sink +drain, writer ordering, decoder bounds, and header-ACK hardening remain +unconditional correctness fixes. + +Production deployment does not form arbitrary mixed-build main/relay pairs. +`computeRemoteRelayDir` content-hash-scopes the install directory and its +socket/named-pipe endpoint, and the `.version` handshake is a second fence, so +the desktop bridge and daemon reached at that endpoint share a build. The +normal same-build mode is session-granted V1. A missing mandatory session grant +fails readiness except for the narrow method-not-found compatibility fallback +above. Protocol tolerance for unknown fields remains for direct/manual relay +launches, but an absent session contract outside that fallback is diagnostic +`unsupported-version-skew`, not a deployment cohort. + +The reachable upgrade skew is an orphaned prior-version daemon in its old +version directory with live PTYs while the new main connects to a new endpoint. +It retains its old behavior until its own grace/cleanup completes and is not +reachable by a new same-build session. Upgrade diagnostics enumerate +these versioned orphan processes; V1 neither adopts their PTYs nor claims to +bound their memory. + +Unknown fields are never capability proof. Place the transport-neutral state +types with the narrowest shared session package, while relay/daemon/runtime +wire types remain in their current protocol packages. Do not make the local +provider depend on relay framing for code reuse. + +### Data and ACK schema + +Flow-controlled output is: + +```ts +// relay -> one subscribed client +{ + jsonrpc: '2.0', + method: 'pty.data', + params: { + id: string, + ptyIncarnation: string, + data: string, + deliveryToken: string, + clientGeneration: number, + ownerGeneration?: number, + sourceEndSu: number, + sourceLengthSu: number, + seq?: number, + rawLength?: number, // required and equals sourceLengthSu when transformed + transformed?: true + } +} +``` + +For untransformed frames, `sourceLengthSu = data.length` and `rawLength` is +absent or equal. For `transformed: true`, `rawLength` is required, finite, +safe, non-negative, and equals `sourceLengthSu`; display length is never used +as source credit. A violation cancels the token as malformed. `sourceEndSu` is +the monotonic cumulative coordinate within one opaque `ptyIncarnation`, not a +display offset. A new token starts with `sentEndSu == creditedEndSu` at its +declared checkpoint, so its absolute coordinate still satisfies the window +equation. The source interval is +`[sourceEndSu - sourceLengthSu, sourceEndSu)`. It is independent of `seq`, +which remains the terminal-model source sequence. + +The wire does not send `providerGeneration` or `spanId`. Main supplies its +locally allocated provider generation and derives +`spanId = deliveryToken:sourceStartSu:sourceEndSu`; together with `id`, +client/owner generations, incarnation, token, source/display ranges, and +transform metadata, that forms the immutable admission identity. No later +queue, snapshot, ACK, detach, or replacement path may reconstruct identity +from PTY ID, byte count, or display length alone. + +ACKs are cumulative and coalescible. Main holds the latest settled end per +token and emits at most one batched notification per SSH session every 8 ms, +or immediately when any token frees at least 64 Ki su: + +```ts +{ + jsonrpc: '2.0', + method: 'pty.ackData', + params: { + acknowledgements: Array<{ + id: string, + deliveryToken: string, + clientGeneration: number, + ownerGeneration?: number, + creditedEndSu: number + }> + } +} +``` + +One frame contains at most 64 latest-value entries; another turn handles the +remainder. Replacing a queued entry for the same token is lossless because the +value is cumulative. ACK frames use the reserved control lane and never one +frame per data frame. + +The relay normally accepts an entry only from the owning dispatcher client and +only when `creditedEndSu` is a finite safe integer satisfying +`previousCreditedEnd <= creditedEndSu <= sentEnd`: + +```text +if creditedEndSu > previousCreditedEnd: + creditedEnd = creditedEndSu +``` + +Negative, non-finite, unsafe, fractional, over-credit, wrong-client, wrong-PTY, +unknown-token, and stale-token values are rejected and counted diagnostically; +they never clamp into valid credit. Duplicate and regressing values are +no-ops. Token generation, not PTY ID reuse, defines the credit lifetime. + +The writer callback is not guaranteed to run before main processes and ACKs an +accepted frame. If an ACK reaches the relay while that exact same-token send +reservation is pending, the ledger records only its exact source-end boundary; +`sentEndSu` and `creditedEndSu` do not advance yet. Successful send settlement +commits the boundary and immediately applies the reservation. Failed +settlement rolls back the send but retains the reserved boundary, so the next +send must reproduce that exact boundary and cannot admit a shorter or later +slice. Cross-token, interior-boundary, and excessive early ACKs remain errors. + +Explicit cancellation is a request so main receives proof: + +```ts +// main -> relay +{ + method: 'pty.cancelDelivery', + params: { + id: string, + deliveryToken: string, + clientGeneration: number, + ownerGeneration?: number + } +} +// result +{ canceled: true, sentEndSu: number, creditedEndSu: number } +``` + +The relay validates client/PTY/token ownership, changes the token to `closing`, +removes its cursor and activation/exit fences, then responds through the control +lane. Duplicate cancellation of the same recently closed token is idempotent. +Main may discard open obligations only after this response drains back through +the mux or the client-generation close proves equivalent cleanup. + +Every relay-initiated token close emits this metadata-only control +notification before the token record is forgotten: + +```ts +{ + method: 'pty.deliveryCanceled', + params: { + id: string, + deliveryToken: string, + clientGeneration: number, + ownerGeneration?: number, + reason: string, + sentEndSu: number, + creditedEndSu: number, + remainingStartSu: number, + remainingEndSu: number, + replacementDeliveryToken?: string + } +} +``` + +It covers supersession, activation/exit timeout, reconnect-grace expiry, and +explicit delivery cancellation. `remainingStartSu == creditedEndSu` and +`remainingEndSu == sentEndSu` state the exact source interval still unsettled +at the relay. If the sink cannot drain the proof, its generation close is the +proof. Without a replacement, main cancels the matching remaining obligations +and schedules restore/reattach. With a replacement, it keeps those obligations +in `transferring` until replacement `pty.data` and its fence prove exact contiguous +coverage, then atomically transfers the covered suffix. Any prefix already +included in the proved model checkpoint is canceled as superseded without +re-ingestion; an uncovered or mismatched remainder cancels with +`restoreRequired` instead of being credited. Every source subrange therefore +settles once. Stale generations are ignored. + +### Activation, replay, and idempotent spawn + +Token creation and response publication are one fenced operation. The exact +activation metadata carried by V1 spawn and attach responses is: + +```ts +type PtySourceReceivingActivation = Readonly<{ + status: 'pending' + clientGeneration: number + ownerGeneration: number + ptyIncarnation: string + deliveryToken: string + checkpointSourceEndSu: number + recoveryEndSu: number +}> + +type SpawnResult = { + id: string + incarnationId: string + sourceActivation?: PtySourceReceivingActivation +} + +type AttachResult = { + incarnationId: string + replay?: string + sourceActivation?: PtySourceReceivingActivation + sourceRecovery?: + | PtySourceReceivingActivation + | Readonly<{ status: 'restoreRequired'; reason: string }> +} +``` + +The dispatcher places the metadata-only response on the response lane and +invokes the request's `onResponseSettled` callbacks only from the exact writer +settlement. Success clears relay activation; failure cancels a fresh token or +leaves the exact recovery attempt available to its proved replacement. +Enqueue, `write(true)`, and `write(false)` alone are not activation proof. + +The main mux supplies the receive fence. Spawn and attach requests register a +synchronous `beforeResolve(result)` hook in their pending-request record. +`handleResponse` parses the whole response and provisionally installs +`sourceActivation` before resolving the Promise. The lease captures the exact +prior receive state, candidate token, and a private ordered list of same-turn +source frames. Spawn and non-recovery attach commit only after operation-ID +result, incarnation, claimed-owner, attach identity, stale-attempt, and exit +validation. Reconnect first validates the owner, incarnation, token, +checkpoint, and recovery end, installs the exact private quarantine, then +transfers the lease to its private sink before awaiting the body/completion +fence. That transfer cannot update ordinary provider listeners or +`livePtyIds`, and it cannot reach the model, runtime, desktop, or remote +consumers. Final commit switches future exact-token frames to ordinary +publication only after the body, fence, model admission, and activation +validation succeed. Any failure before transfer +retires the candidate and drops its held data, restores only the nearest +non-retired predecessor, then waits for a valid `pty.cancelDelivery` response +from the originating mux. After transfer, recovery cancellation or +provider-generation close owns cleanup; rollback is no longer authoritative. +It cannot erase a newer revision or cancel a newer token. An identical +already-committed activation is an idempotent no-op; an identical provisional +activation is stale. Fresh-spawn rollback that cannot prove cancellation +surfaces `execution_owner_unavailable` rather than claiming the old token +retired. + +The receive cursor starts at `checkpointSourceEndSu`, not +`recoveryEndSu`. Source-bearing notifications for the installed identity may +then advance only contiguously. Frames through `recoveryEndSu` stay +quarantined as recovery; later frames stay held until the exact completion +fence commits. Unknown or mismatched source identities are rejected before +`livePtyIds`, runtime, renderer, or source obligations change. Exact +source-bearing frames carry their immutable `ptyIncarnation` directly and do +not invoke or mutate the legacy incarnation resolver. + +Every exact-token private frame advances a monotonic observed-source high-water +before quarantine retention or `restoreRequired` checks. If exact exit arrives, +main wakes the recovery fence and seals the private lease immediately. It may +publish exit only after the held contiguous prefix is admitted, or after +`pty.cancelDelivery` proves `sentEndSu` covers that high-water and the accepted +checkpoint remains the credited end. Capacity-rejected and post-restore frames +therefore cannot disappear below the cancellation proof. + +Output produced while a token is activating is retained by its bounded shared +cursor and can pause the native PTY; it is never sent early. Output arriving +after main's synchronous install but before authority commit is bounded by the +provisional lease and is not visible to runtime, desktop, remote consumers, or +`livePtyIds`. Main drops unknown-token notifications before any side effect. + +Before issuing attach or any same-client replacement, main serializes each +`(providerGeneration, appPtyId)` through a migration fence: freeze new +old-generation intake, cancel queued-but-unstarted model entries, await the one +in-flight emulator callback, then record the last completed receipt. A later +overlapping reconnect preserves and awaits an earlier fence for the same PTY; +an empty newer generation cannot expose the earlier checkpoint. Before the +deadline, every old callback remains owned by its admission and generation +until raw completion settles. Stale-owner retry invalidates the checkpoint +value but retains the same fence, then requests restore after it settles. If +the 10-second migration deadline expires or the callback fails, admission +checks the exact active migration before its generation-fatal default. Main +cancels only that admission, detaches that PTY's old headless model, prefers +provider/renderer snapshot restore, and requests `checkpointUnavailable`; +recovery reports `restoreRequired` instead of replaying a guessed gap. The +shared mux, sibling PTYs, filesystem, and Git traffic remain live. Outside an +active exact-PTY migration, the same callback failure still closes its provider +generation. Late raw completion stays on the detached model and cannot advance +the canceled source checkpoint. + +Attach sends `sourceRecovery: { status: 'checkpoint', clientGeneration, +ownerGeneration, ptyIncarnation, deliveryToken, acceptedSourceEndSu }`. A +queued, in-flight, or merely rendered span is not a checkpoint. Without a +proved fence it sends `{ status: 'checkpointUnavailable' }`. + +The relay accepts the checkpoint only for the same incarnation and within +`[oldCreditedEndSu, retainedLiveEndSu]`. It never clamps a value forward, +trusts a value beyond sent/retained data, or replays freed pre-credit source; +an invalid or uncovered checkpoint cancels the attempted delivery and returns +the token-free `restoreRequired` arm. The canceled record remains installed and +cancellation-authoritative until that metadata response settles. Settlement +deletes it only if the delivery map still points to the exact record and wakes +capacity; a retry can then mint a fresh token. It does not activate a +subscription or stream a partial gap; main either restores an authoritative +model generation before retry or surfaces the gap. + +The reconnect coordinator consumes `restoreRequired` and owns snapshot-backed +replacement. A generic existing-session provider reattach has no such recovery +owner, so it maps `restoreRequired` to `SSH_SESSION_EXPIRED` instead of +returning an outputless live PTY; the existing renderer fallback may then +replace that stale session. + +Recovery bodies use the ordinary source-bearing `pty.data` schema. The new +token initializes `sentEndSu = creditedEndSu = checkpointSourceEndSu`, and +the retained gap covers exactly +`[checkpointSourceEndSu, recoveryEndSu)`. Each frame consumes the normal +window and bounded model admission; there is no separate recovery body method, +stream ID, or replacement-only snapshot kind on this SSH wire. + +Only after the last recovery `pty.data` writer callback succeeds does the relay +attempt this metadata-only control notification: + +```ts +{ + method: 'pty.recoveryComplete', + params: { + id: string, + clientGeneration: number, + ownerGeneration: number, + ptyIncarnation: string, + deliveryToken: string, + checkpointSourceEndSu: number, + recoveryEndSu: number + } +} +``` + +`recoveryCompletionPending` permits one admitted attempt at a time. If control +capacity rejects it before admission, the record retains both range ends and +the capacity callback retries; repeated capacity signals cannot enqueue +duplicates. Only the completion notification's successful writer settlement +clears recovery state and permits buffered live `pty.data`. A failed +settlement leaves recovery fenced for exact owner replacement or cleanup. + +Notification-style `pty.replay` remains the legacy attach compatibility path. +`pty.serialize` remains its existing bounded metadata response; neither is a +second V1 source-recovery body channel. + +Main quarantines the entire candidate recovery transaction until it can prove +the fence. The first source-bearing recovery range must start at the accepted +checkpoint, every later range must be exactly contiguous, and the final end +must equal `recoveryEndSu`. Empty recovery is valid only when the checkpoint +already equals `recoveryEndSu`; main retains that end as the required start of +the first later live frame even after activation. The first live frame and +every successor must also be exactly contiguous. Gap, overlap, incomplete +suffix, missing body, bad empty recovery, or bad live handoff reaches neither +the model nor desktop projection. + +A failed or stale recovery attempt cancels only its own replacement token. +It never sends cancellation on a newer mux, clears a newer checkpoint, shuts +down the physical PTY/process, deletes PTY ownership, or expires the owner +lease. A valid matching token-scoped cancellation proof is applied locally and +leaves the lease detached and retryable. If the current attempt cannot publish +cancellation or local proof application rejects, the session fails closed: +it closes the exact provider generation with +`ssh_source_recovery_cancellation_failed`, disposes that generation's mux, +provider, ACK/cancellation publishers, provisional lease, and registration +once when still provisional, or its transferred activation state after +quarantine ownership begins, and reconnects without clearing physical PTY +ownership. If the attempt is already stale, it performs no cleanup against the +replacement. A fresh +relay that no longer retains the cached owner returns typed error `-32041`; +main clears only the cached owner/checkpoints and retries `pty.openClient` +exactly once without `resume`. + +Idempotent agent-session spawn has two layers. The cached +`agentSessionCreateOperationId` promise returns only the physical PTY +identity/outcome. After that promise resolves, every current, non-stale outer +`pty.spawn` request creates its own requesting-client subscription and +activation fence. Creating a token for an existing +`(clientId, clientGeneration, ptyIncarnation)` is one atomic supersession +transaction: create the replacement cursor first, move the old token to +`closing`, cancel its outstanding activation/exit work, emit +`pty.deliveryCanceled(reason='superseded')`, and return the old token in the +new response. The cancellation names the replacement token and exact remaining +old span. Main transfers that span only after matching recovery completes; +otherwise it cancels it and restores. The pair therefore has at most one +active token and no range is both canceled and replayed as new model input. A +retry served from the cache receives one fresh token, never a duplicate live +subscription. If the client becomes stale after physical commit, no token +survives; the next retry can subscribe to the retained PTY. + +## Relay output architecture + +Split policy from lifecycle and transport: + +- `pty-source-credit-ledger.ts`, `pty-source-credit-record.ts`, and + `pty-source-replay-index.ts` own cumulative token state, immutable retained + source records, exact replay ranges, rotation, and reclamation. +- `relay-pty-source-publication.ts`, + `relay-pty-source-activation.ts`, + `relay-pty-source-send-scheduler.ts`, and + `relay-pty-source-exit-publication.ts` own activation/restore settlement, + 16 Ki-su publication, recovery, exit barriers, budgets, and subscriber + scheduling. +- `dispatcher-client-writer.ts` owns the one writer per sink, activation + fences, lane queues, drain callbacks, and close settlement. + +`PtyHandler` retains PTY lifecycle, the 8 ms initial/1 ms continuation cadence, +immediate interactive/transformed publication, replay tail, streaming +transform state, and idempotent native `pause()`/`resume()`. It publishes +immutable source spans rather than broadcasting notifications. + +### Cumulative span ledger + +Each PTY ledger is append-only until every cursor has passed a span: + +```ts +type RelaySourceSpan = { + spanId: number + sourceStartSu: number + sourceEndSu: number + data: string + splittable: boolean + retainedBytes: number +} + +type PtyDelivery = { + state: 'activating' | 'recovering' | 'active' | 'sealed-unsettled' | 'closing' | 'closed' + clientId: number + clientGeneration: number + ownerGeneration?: number + deliveryToken: string + cursor: { spanId: number; displayOffset: number; sourceOffsetSu: number } + sentEndSu: number + creditedEndSu: number +} +``` + +Different subscribers may stop at different offsets in one span. A cursor +contains both display and source offsets, so no global chunk split can lose or +repeat a suffix. Data storage may coalesce adjacent splittable spans for a +frame or slice one span per cursor; the immutable source boundaries and +cumulative ends do not change. Reclamation requires every live, activating, +sealed-unsettled, closing, or reconnect-grace cursor to pass the complete +span. Native process exit seals admission but does not weaken reclamation. + +The transform publisher cuts source input into scalar-safe pieces, never +between a surrogate pair, and records each display result against its source +interval. An untransformed span may be 16 Ki su and is sliced per sink. +A transformed span is indivisible after publication, so its publisher reduces +the source slice until the encoded span is at most 8 KiB, below the token +window, and no larger than the sink's empty non-reserved capacity. An +implementation that cannot stream a transform must pause before the hard limit +and request model restore; it may not over-credit, truncate, or send an +oversized or permanently inadmissible frame. + +The existing 100 Ki-su replay-tail policy and the chunked +`RecentPtyOutputBuffer` representation from `79ec57d04` remain. +`PtySourceReplayIndex` now provides the bounded parallel source-range index +without restoring the former rolling-string re-slice. Legacy replay still +materializes the same display tail. V1 restore additionally preserves +incarnation, exact source ranges, and transform metadata. Index eviction +follows the buffer's exact retained prefix and never fabricates a mapping; the +existing append-path equivalence/performance contracts remain in force. + +### Scheduling and fairness + +The relay scheduler uses deficit round-robin over PTYs, then rotates subscribed +clients for the selected PTY. One scheduling turn admits at most: + +- two PTY frames; +- 32 Ki su; +- 2 ms of scheduler work. + +Requeue work with `setImmediate` after any limit. Input and control requests can +therefore interleave with output. A recent-input PTY may move to the front once +per round, but repeated interactive classification cannot consume another +PTY's quantum. Preserve the existing bounded interactive fast path: after any +already-queued liveness/control frame, if its token is active, has no earlier +backlog, remaining window covers the exact slice, and the writer admits it +without reserve use, publish one echo frame of at most 4 Ki su immediately +instead of waiting for the 8 ms timer or DRR. Allow at most one such frame per +input epoch; it advances the same cursor once and then yields to normal +priority selection. + +For each live/interactive candidate, all gates must be open: + +```text +frameSourceLengthSu <= windowSu - (sentEndSu - creditedEndSu) +client writer admits PTY bytes without consuming its control reserve +token state == active +``` + +For a splittable span, the admitted slice is at most +`min(16 Ki su, remainingWindowSu)`. An indivisible transformed span is admitted +only when its entire source length fits. There is no one-frame window +overshoot. Dispatcher admission creates one pending send reservation. A +`write(false)` still gives Node that frame exactly once, but the cursor and +`sentEndSu` commit only on successful writer settlement; failure rolls back +the reservation. No later ordinary frame is admitted meanwhile. Unsent frames +remain ledger-owned. Liveness, control, interactive PTY, ordinary source PTY, +and bulk are reconsidered on every writer turn. Recovery and live output use +the same source-bearing `pty.data` producer; recovery additionally requires +`token state == recovering`, exact continuity, byte capacity, and +remaining-window capacity. + +The V1 source owner and additional subscriber projections use independent +publication transactions: +`projectPtyDataToMatchingClients`/`projectPtyExitToMatchingClients` exclude +the `source-owner` and reserve each remaining client separately. If one +additional subscriber cannot reserve bounded writer/publication capacity, +close only that client and continue the healthy subscriber and source-owner +sends; never pause or tear down the native PTY solely for that projection. A +legacy-fallback primary is different: it remains a required bounded-legacy +backpressure participant and is not evicted for saturation. Constructor +position still grants no session-owner role. + +Pause when every remaining delivery is blocked or either retained-byte hard +cap is reached. Resume only when: + +```text +perPtyRetainedBytes <= 1 MiB +relayRetainedBytes <= 48 MiB +at least one delivery can advance, or no delivery remains +``` + +Both predicates are required; the per-PTY low water cannot immediately resume +while the relay-wide budget remains exceeded. Calls are idempotent because a +last `node-pty` callback may re-enter pause/exit handling. + +### Exit + +On native exit, seal the PTY's output stream after publishing the last ingress +emissions. The source-owner delivery changes to `sealed-unsettled`; additional +subscriber exits use their independent bounded projection transactions: + +1. write all preceding data within normal window and drain rules; +2. once that data is accepted by the sink, write `pty.exit` without waiting for + the final data ACK; +3. record the exit write callback as `exitPublished` only on explicit success; + on error, generation-close/cancellation proof owns cleanup. Retain the + delivery, token ledger, cursor, cumulative ACK state, and timeout while any + `[creditedEndSu, sentEndSu)` suffix remains; +4. close only when the outstanding suffix becomes terminal through cumulative + ACK application at the relay, exact transfer to a replacement, explicit + cancellation, or client-generation close proof. + +Never force a final tail past the credit window. An additional subscriber that +cannot admit its projected `pty.exit` is detached without changing the source +owner. For the session owner, cancel only this PTY token after its bounded +deadline, keep the sealed record until ACK, transfer, cancellation, or +generation-close proof, and do not tear down unrelated PTYs. A late valid ACK +against a sealed token remains valid and may complete cleanup. Sealed records +are excluded from the 50-live-native-PTY spawn admission count but remain +charged to retained-data budgets. Relay disposal generation-closes all +records and clears their scheduled work exactly once. Exit listeners and +native PTY disposal run at physical exit; logical delivery cleanup waits for +proof. + +Main has a matching receive-exit barrier. Receiving `pty.exit` seals the token +against later data but does not immediately call `runtime.onPtyExit`, retire +the headless emulator, clear desktop ranges, close remote subscriptions, or +send renderer exit. It retains every preceding model receipt, projection ID, +remote mapping, and ACK publication record. In order, it: + +1. waits for preceding model receipts; +2. publishes or exactly transfers committed desktop ranges and required + remote mappings; +3. advances/queues the terminal cumulative source ACK; +4. then invokes runtime and renderer exit cleanup while retaining ACK + publication state until success or generation-close proof. + +The barrier has the same charged 30-second deadline. At expiry, main first +sends token-scoped `pty.cancelDelivery` and waits up to 10 seconds for its +proof without applying it. If the exact barrier/generation still owns the +exit, main transfers published desktop projections to +`ssh-exit-delivery-canceled`, commits the proof to reclaim source spans, +prepares exit once, rechecks generation ownership, finalizes exit, rechecks +again, then closes the projection. This order prevents proof commit from +reclaiming a span before its published projection transfers. + +If provider-generation close wins while proof is pending, it rejects and +removes the barrier plus its preparation ownership; cancellation ownership is +operation-local rather than retained in a process-lifetime tombstone. The late +proof performs no transfer, commit, preparation, final exit, or projection +close. If cancellation publication or proof fails while the barrier remains +current, main closes the provider so generation cleanup proves cancellation; +unrelated PTYs are not torn down on the ordinary successful timeout path. A +late emulator callback cannot mutate the reset generation. Thus relay sink +ordering and main asynchronous model ordering are both proved. + +Provider generations come from one process-wide monotonic allocator and are +never reused. Main rejects closed generations through sorted, merged inclusive +ranges rather than one retained entry per reconnect. Sequential closes compact +to one range; out-of-order closes preserve exact live-generation gaps until +those generations close, then merge. This keeps stale-generation rejection +exact while retained range count follows live gaps instead of process uptime. + +## Dispatcher and transport drain + +Every dispatcher client is constructed with one bidirectional transport: + +```ts +type SinkWriteResult = 'accepted' | 'saturated' | 'closed' +type SinkWriteSettlement = { ok: true } | { ok: false; error: Error } + +type RelayClientTransport = { + write(data: Buffer, onSettled: (result: SinkWriteSettlement) => void): SinkWriteResult + writableLength(): number + writableHighWaterMark(): number + onDrain(cb: () => void): () => void + pauseReads(): void + resumeReads(): void + close(): void +} +``` + +Adapters map Node `true` to accepted, `false` to saturated, known-dead to +closed, and map the `stream.write(data, callback)` callback's optional error +to explicit success/failure settlement. Only `{ ok: true }` is a publication +fence. A callback error or thrown error closes the client, cancels the +generation, and cannot activate a token, publish ACK state, or release a source +obligation. A saturated or closed transport is never called again for ordinary +traffic before drain/replacement. +One 13-byte keepalive may bypass a saturated epoch; no second liveness bypass +is allowed until that write callback or drain, so the exemption is constant +space rather than an unbounded queue. + +`DispatcherClientWriter` is the only encoder/writer for a client. It owns: + +1. a coalesced liveness lane, at most two 13-byte frames; +2. a FIFO control lane, at most 256 frames and 1 MiB encoded; +3. producer-scheduled interactive PTY, ordinary source PTY, and bulk lanes, + whose frames remain with their producers until the writer admits them. + +It reserves +`min(64 KiB, max(1 KiB, floor(highWaterMark / 4)))` below the stream's +high-water mark for liveness/control. PTY, recovery, and bulk admission all +require +`writableLength + frameBytes <= highWaterMark - effectiveReserve`; the +scheduler reduces source slices and reshapable bulk before publish. The +`fs.streamChunk` wire contract is the exception: its fixed 256 KiB raw chunk +and sequence-offset math are preserved, and the `fixed-bulk` lane admits one +encoded frame only when the producer queue and writable sink are empty and +unsaturated. It then obeys ordinary callback/drain settlement before another +producer frame. No producer writes around these gates. +Every transport accepted for a PTY subscription must expose at least 8 KiB of +empty non-reserved capacity. A lower-capacity subscriber is rejected before +token creation, so an already-published indivisible transformed span cannot +become permanently inadmissible. +Liveness is selected first, then control FIFO, interactive PTY, ordinary source +PTY, and bulk; after one producer frame the writer re-runs selection. The +physical stream is still FIFO—V1 does not claim a second SSH channel—but the +finite burst and byte reserve bound head-of-line delay. Control overflow closes +an additional subscriber; overflow on the negotiated session owner is a +transport failure and reconnects that owner generation. + +Drain registration is one-shot per saturated epoch. `close`, `error`, +`attachClient`/`detachClient`, owner-generation replacement, and dispose +cancel every outstanding write callback and producer fence exactly once. +`setWrite` remains a test/compatibility seam; production reconnect ownership is +the socket/stdin construction plus `attachClient` and `detachClient`. + +In detached relay startup, immediately invalidate the synthetic stdout client +when `stdoutAlive` becomes false. A no-op writer must not look like successful +delivery. The first valid session-owner grant on an `attachClient` +socket/named-pipe client elects the owner; reconnect resume replaces its +generation atomically. Constructor identity and connection order confer no +role. + +One `DrainAwareStdoutWriter` owns every byte written to `process.stdout`, +including the initial relay sentinel, handshake residue, dispatcher frames, +and connect-mode forwarding. `runConnectMode` performs +`sentinel -> residue -> socket data` through that writer and pauses the source +socket after stdout saturation; it never mixes ad-hoc `stdout.write()` with +`sock.pipe(stdout)`. The same state contract wraps Unix sockets, Windows named +pipes, and the initial stdio client. + +Keepalive frames are independent of PTY credit, use reserved capacity, and have +the single-frame saturated-epoch exemption above. A decoder self-pause or +local writer-saturation epoch suspends dead-link evaluation. Resume calls the +same `rebaseHealthClocks(now)` used after a wake gap: set `lastReceivedAt` and +every existing `unackedTimestamps` entry to `now`, then allow a full timeout +window. Rebasing only received-data age is insufficient because the +outstanding-header-ACK conjunct would remain stale. During a suppressed +interval, keepalive intent coalesces behind one outstanding probe and the +header-ACK timestamp map has a hard entry cap; at 4095 entries it stops +ordinary main-to-relay admission and reserves the final coalesced entry for +cancel/liveness. +No pause fabricates an ACK. Tests sustain both states past 20 seconds and prove +zero reconnect oscillation or timestamp growth. + +## Main-process credit ownership + +`SshRelaySession.wireUpPtyEvents` remains the provider listener but stops +calling `runtime.onPtyData` and `webContents.send` itself. It validates the +provider generation/token and hands each notification once to a main-only +`SshPtyOutputDelivery` intake installed by `src/main/ipc/pty.ts`. This intake is +the only SSH owner allowed to ingest runtime output, mutate delivery state, or +send `pty:data`. + +### Main cumulative ledger + +The intake appends immutable wire spans: + +```ts +type PtySourceDeliveryIdentity = Readonly<{ + id: string + providerGeneration: number + clientGeneration: number + ownerGeneration: number + ptyIncarnation: string + deliveryToken: string +}> + +type PtySourceSpan = PtySourceDeliveryIdentity & + Readonly<{ + spanId: string + sourceStartSu: number + sourceEndSu: number + displayStart: number + displayEnd: number + data: string + splittable?: boolean + indivisible?: boolean + transform: { + transformed: boolean + rawLengthSu: number + scalarSafe: boolean + } + }> + +type SourceSpanRecord = { + span: PtySourceSpan + obligations: Map +} + +type SpanObligation = + | { state: 'open' } + | { state: 'transferring'; to: ConsumerId; reason: string } + | { state: 'settled'; reason: string } + | { state: 'transferred'; to: ConsumerId; reason: string } + | { state: 'canceled'; reason: string } + +type TokenAckPublication = { + obligationsTerminalEndSu: number + ackQueuedEndSu: number + ackPublishedEndSu: number +} + +type DesktopProjectionSpan = Readonly< + Omit & { + splittable: boolean + projectionSemanticsId: string + } +> +``` + +The ledger is separate from `PendingPtyData`. Queue merge, split, remainder, +drop sentinel, query salvage, thinning, and interactive bypass receive no +delivery token and cannot rewrite source spans. At SSH intake, +`SshPtyLegacyProjectionLedger` keeps per-PTY cursors and admits the complete +immutable `DesktopProjectionSpan`; it never receives only `data` plus source +length. +`PendingPtyData` continues to store display batching fields plus an opaque +projection admission ID, not mutable source accounting. + +`projectionSemanticsId` addresses an immutable per-admission record containing +the accepted chunk's ordered main-authoritative terminal facts and the +projection queue's before/after bounded scanner snapshots. This preserves +current main's dropped-output DEC mode 2031 subscribe/withdraw salvage without +putting mutable scanner state in the source ledger. A source gap resets the +recorded cross-chunk state before later bytes are admitted. + +When the data queue sends a display prefix, drops a pending entry, or replaces +it with salvage, it asks the range queue to consume the same operation. The +range queue—not mutable `rawLength` fields—returns the exact source length and +transform metadata for the renderer payload and consumer obligation. +Admission is transactional: + +1. reserve model bytes and create the source span; +2. stage the main terminal facts and before/after projection scanner snapshots; +3. reserve the exact desktop range by `spanId` and `projectionSemanticsId`; +4. enqueue display data and publish only after every reservation succeeds; +5. commit model ownership, main facts, and projection admission together. + +If model reservation fails, remove every uncommitted reservation. If +projection admission or `webContents.send` fails, roll back the uncommitted +range selection and restores the prior projection scanner snapshot without +publishing staged facts. After model commit, main facts remain published once +and a send failure atomically transfers the desktop obligation plus committed +projection state to a model-restore marker. Queue merge/split preserves the +ordered admission IDs, salvage/drop transfers exact superseded ranges and DEC +mode 2031 decisions, renderer reload transfers committed desktop obligations +before clearing, and token replacement rejects stale IDs by generation while +exact replacement coverage transfers their ranges. Untransformed source may +split only at a recorded display/source offset; a transformed range stays +indivisible. No rollback fabricates an ACK or destroys a live relay +obligation. Renderer ACK retirement reserves both range and ledger mutations, +validates both, then performs one no-throw commit; neither side becomes +terminal before that commit. + +Development assertions enforce: + +```text +receivedSu = openSu + transferringSu + settledSu + transferredSu + canceledSu +obligationsTerminalEndSu = + largest contiguous end whose required obligations are terminal +ackPublishedEndSu <= ackQueuedEndSu <= obligationsTerminalEndSu +``` + +Only `SshPtyOutputDelivery` may call the V1 cumulative ACK coalescer. The +generic `IPtyProvider.acknowledgeDataEvent(id, delta)` API remains for local +and daemon behavior. Legacy-fallback SSH may still emit its current delta, but +the relay ignores it and no legacy bound depends on it; it is a hard no-op for +negotiated V1 PTYs. At every shared `pty:ackData`, resync, heal, +write-off, drop, salvage, and reload call site, V1 routes renderer display +progress through +`SshPtyLegacyProjectionLedger`: parsing settles exact mapped source ranges and +heal/write-off atomically transfers them. These projection transitions may +advance ledger eligibility already earned by the model, but never emit legacy +`{ id, charCount }` wire traffic or manufacture source progress from a display +count. + +ACK eligibility and ACK publication are separate transitions. Terminal +obligations advance `obligationsTerminalEndSu` without waiting for a write +callback. The coalescer independently queues the latest cumulative eligible +end and advances `ackQueuedEndSu`. The mux write callback advances +`ackPublishedEndSu` and permits cleanup only on explicit success; it never +creates eligibility. A synchronous throw, callback error, or close leaves the +cumulative value queued for a generation-aware retry or reaches cancellation +proof on provider close. Coalescing replaces only with a greater cumulative +value, so retries cannot lose an eligible prefix. + +### Bounded asynchronous model admission + +The charged FIFO per PTY and global scheduler replace the unmetered +headless-emulator `writeChain` contract. `acceptPtyData` returns a Promise +receipt: + +1. before capturing the frame, reserve its charged retained bytes against the + per-PTY and global model-admission budgets; +2. the per-PTY budget covers one full token window and the global budget + matches the relay retained-data cap, so a conforming owner reaches token + backpressure before routine admission denial. If a transient frame still + cannot fit, keep that current decoded frame in a separately charged intake + slot and leave its model obligation open. Enter selective pressure mode: + quarantine at most 1 MiB or 64 later PTY data frames in wire order while + continuing to apply transport liveness, unrelated RPC control, and + cancellation proofs. Keep `pty.exit`, `pty.recoveryComplete`, activation + fences, and other source-ordering lifecycle frames behind all preceding + quarantined data for their token. A same-token cancellation proof may bypass + only by atomically canceling those quarantined obligations first. Do not + admit quarantined data out of order. If the reserve fills before capacity + returns, pause reads and start a 10-second provider-close deadline; +3. enqueue only after capacity is owned. Snapshot all consumer memberships and + allow bounded desktop/remote fan-out at that point; neither projection + progress nor queue ownership settles the required model obligation. + Preserve per-PTY order while allowing fair turns across PTYs; +4. resolve the receipt only from the emulator write callback. Then release the + queue charge, settle the model obligation, and advance eligible credit; +5. resume admission only after both low waters hold. Rejection cancels the + token and schedules restore; it never passes through the current + best-effort swallowed-error path. + +The relay writer rechecks control priority after every PTY frame, so the +receive reserve needs to cross only a bounded already-written PTY burst, not an +unbounded producer stream. If no control can be reached within the reserve and +deadline, provider close supplies generation cleanup proof. Selective pressure +never settles, drops, or reorders a data frame and never lets a model stall +silence cancellation indefinitely. + +Provider close, token supersession, PTY exit, and runtime disposal cancel +queued-but-unstarted entries and reject their receipts exactly once. An +in-flight emulator callback owns its entry until completion or failure and +must pass its captured token/generation check before committing. Reconnect and +supersession use the migration fence above rather than letting that callback +race a replacement checkpoint. Failure dispatch consults the exact +`(providerGeneration, ptyId)` migration owner before invoking generation close; +this does not suppress the ordinary non-migrating failure policy. The old +Promise chain may remain as the per-PTY execution primitive only after each +link is charged by this scheduler; it is no longer an unbounded owner. + +### Desktop, mobile, web, and agent policy + +Consumer membership is snapshotted when each span arrives: + +- The main terminal model is always required. + `runtime.acceptPtyDataBounded` returns the asynchronous receipt Promise + above; it resolves only after the emulator accepts the span. + Status and agent-session observers derived from that model add no duplicate + obligation. +- The desktop renderer is a recoverable projection. Parsing settles its + obligation. Hidden thinning, reload, destroyed-window, send failure, + pending-cap replacement, or delivery heal atomically transfers the + obligation to the already-accepted main model and emits a model-restore + marker before settlement. A transfer requested before the model receipt + remains pending and commits only when that receipt succeeds. Once the model + receipt exists, desktop obligations + remain tracked for main-to-renderer bounds but are not required for upstream + ACK eligibility. +- A mobile/web/raw agent terminal subscriber that negotiated lossless ACKs is + required while attached and settles independently from its bounded delivery + cursor. At its ACK cap it stops sending and remains required; a stall cannot + auto-transfer itself out of upstream backpressure. On explicit detach or + replacement, transfer to a snapshot/resubscribe marker if supported; + otherwise cancel that consumer and close only its stream. +- A legacy or observational remote subscriber is best-effort and creates no + upstream obligation. It receives bounded fan-out and is dropped/resynced on + overflow. + +Current mobile notification replay remains a separate runtime method and +identity space. Its notification epoch and post-local-delivery watermark prove +notification catch-up only; terminal obligations require the stream generation +and immutable encoded-byte/source-range mapping below. + +The token ACK advances when the main model and every currently required +lossless consumer for the contiguous prefix have terminal obligations. A +desktop stall therefore cannot freeze a healthy mobile/web consumer, while an +actually lossless remote subscriber still participates explicitly. + +Each lossless remote stream owns an immutable encoded-byte/source-range ledger: + +```ts +type LosslessRemoteSendRange = { + streamGeneration: string + encodedStartByte: number + encodedEndByte: number + providerGeneration: number + ptyIncarnation: string + deliveryToken: string + sourceRanges: ReadonlyArray<{ + spanId: string + sourceStartSu: number + sourceEndSu: number + indivisible: boolean + }> +} +``` + +Existing `terminal.multiplex` `ackOutput: 1` remains a byte-delta flow-control +mechanism and creates no SSH source obligation. A required source-mapped stream +must separately negotiate `ackOutputSourceRanges: 1`. The server allocates an +opaque `streamGeneration` in the subscribed control frame; every cumulative +ACK carries that generation and `ackedEndByte`. A reused `streamId`, old +client, legacy `{bytes}` ACK, or stale generation cannot settle the new stream. + +The mapping is recorded only when the remote writer accepts that exact encoded +output payload, in the same byte unit used by its ACK window. Batching flushes +on provider generation, PTY incarnation, or delivery-token change. When one +encoded frame contains multiple same-identity source spans, it records their +ordered composite list rather than collapsing them into a proportional range. +An ACK must be a finite safe integer in +`previousAckedEndByte <= ackedEndByte <= lastAcceptedByte`; excessive values +are rejected and counted, never clamped into full settlement. An in-range +partial-frame ACK advances the byte watermark and releases exactly that byte +budget, but retains the covering frame's immutable source mapping and settles +no source units. Only complete recorded frame boundaries settle their exact +ordered source ranges. UTF-8 width, JSON escaping, `rawLength`, and display +transforms are never converted proportionally. + +The same attached stream may cross a source-token rotation without transferring +its older unsettled frame. Admission requires the same PTY ID, provider +generation, and incarnation; strictly greater client and owner generations; a +different delivery token; and exact source/display continuity. The ledger then +rebinds future frames to the new identity while older frames retain their own +immutable identity and settle at their encoded boundaries. Equal, lower, +partially advanced, cross-provider, cross-incarnation, or same-token rotations +are rejected. Before stream replacement, snapshot recovery, or detach, create +the replacement owner and atomically transfer every remaining mapping; +otherwise cancel that consumer and its bounded stream. Old stream generations +cannot settle new mappings. + +The main registry stores the immutable source identity with each admitted +remote mapping, not only its `spanId`. A replacement reservation moves the +named consumer obligations to `transferring`; only an accepted headed or +headless `SnapshotEnd` publication at or beyond the reservation's required +sequence commits them. Stale generation, failed publication, disconnect, or +explicit rollback restores the original live-stream obligation. If +token-scoped cancellation proof has already reclaimed the authoritative span, +late ACK/settle prunes the cached mapping, detach skips absent spans, and a +replacement commit returns false without dereferencing the reclaimed record. +Rollback then deletes the exact reservation and skips already-absent spans. +These paths are idempotent and create no credit. + +ACK-pending output overflow uses the same transaction. For a source-mapped +stream, serialize the bounded snapshot, reserve only immutable spans whose +model-sequence end is covered by its `seq` through +`reserveRemoteTerminalSourceRangeReplacement`, publish every snapshot frame, +then call `commitRemoteTerminalSourceRangeReplacement` against the exact +current stream generation, snapshot source identity, and sequence. Only after +commit may the server trim queued chunks with +`chunk.seq <= snapshot.seq` and clear the overflow marker. Serialization, +publication, or commit failure calls +`rollbackRemoteTerminalSourceRangeReplacement`, preserves the live +obligations, reports the stream error, and detaches that stream. One +`ackRecoverySnapshotInFlight` flag bounds the operation to single-flight. +At the encoded-byte ledger, snapshot replacement commit is itself idempotent: +duplicate commits and commits after close are no-ops, preserve cumulative byte +coordinates, and remove only source mappings covered by the authoritative +snapshot sequence. + +The stall policy is deliberately split. Desktop-only parse failure reaches its +bounded projection cap, transfers to model restore, and lets upstream credit +continue. A stalled model receipt or attached lossless remote has no automatic +projection transfer: its required obligation stays open, the token window +exhausts, and the relay pauses the native PTY when every remaining delivery is +blocked. Only an explicit, capability-proven snapshot/resubscribe transition +can transfer a lossless remote obligation. + +### Exactly-once lifecycle + +`settle`, `beginTransfer`, and `cancel` are compare-and-set operations from +`open` for both the upstream token span and each consumer obligation. +`transferring` becomes `transferred` only after the named replacement fence or +becomes `canceled` on mismatch/failure; duplicates are no-ops with diagnostics. +Required obligations becoming terminal advances +`obligationsTerminalEndSu`. That transition makes the cumulative ACK eligible; +it does not wait for ACK publication. The coalescer advances `ackQueuedEndSu`, +and only the later mux write callback advances `ackPublishedEndSu` and allows +record reclamation. A token span begins transfer only when the relay atomically +moves reconnect-grace ownership to a new token and the attach response +declares the new cumulative boundary, or cancels after +explicit/connection-close proof. The transaction creates the replacement +owner before marking source `transferring`; only exact recovery-complete +coverage terminally transfers it. + +| Event | Mandatory transition | +| ----------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | +| spawn/attach response decoded | install provisional `sourceActivation` in synchronous `beforeResolve`;

asynchronous model execution. Desktop/remote fan-out may begin after +the admission budget owns the frame, but the model obligation settles only +after the emulator callback. Admission wait leaves it open and pauses reads at +the charged limit; rejection triggers token cancel rather than acknowledging +data the model did not own. Renderer progress is always display-side input to +the range queue and is never interpreted directly as source units. + +## Incremental frame decoding + +The actual main transport contract is extended as follows: + +```ts +type MultiplexerTransport = { + write(data: Buffer, onSettled: (result: SinkWriteSettlement) => void): SinkWriteResult + writableLength(): number + writableHighWaterMark(): number + onWriteDrain(cb: () => void): () => void + onData(cb: (data: Buffer) => void): () => void + onClose(cb: () => void): () => void + pauseReads(): void + resumeReads(): void + close(): void +} +``` + +`waitForSentinel` constructs these hooks from the real `ClientChannel`: +`channel.stdin.write(buf, callback)`, writable length/high-water mark, and +`on('drain')` for output, plus +`channel.pause()/resume()` for relay stdout. This covers ssh2 and +`SystemSshCommandChannel`, whose stdout-facing channel implements the same +Readable contract. WSL child stdin/stdout exposes the same metrics, +callback/drain, and pause/resume adapter. The startup residue is delivered once +before later data. + +`SshChannelMultiplexer` also owns one main-to-relay writer with exactly three +bounded FIFO lanes: + +1. `liveness` for the coalesced probe, including the one saturated-epoch + bypass; +2. `control` for source ACK, cancellation, exit, RPC request, and response + frames; +3. `ordinary` for `pty.data`, including PTY input/paste traffic. + +The scheduler rechecks priority after every frame and whenever drain reopens +the writer. Liveness wins first. Control wins over queued ordinary traffic +until four control frames have been selected while ordinary remains queued; +the next selection must be one ordinary frame and resets the counter. FIFO is +preserved within each lane. All non-bypass writes still wait for their +per-write callback and `onWriteDrain` after saturation. Producer-side bulk +shaping and fixed filesystem-frame admission remain with their existing +owners; they do not create a fourth mux-writer lane. Thus control cannot remain +behind an old ordinary backlog after drain, ordinary input cannot starve under +a sustained control stream, and V1 ACK settlement has a concrete write fence. + +On the relay, the initial client uses `process.stdin.pause()/resume()` and each +accepted Unix-socket/named-pipe client uses `socket.pause()/resume()`. +`attachClient` accepts those hooks; `detachClient` releases them. Handshake +decoders retain synchronous first-frame behavior and transfer both exact +residue and pause ownership to the dispatcher. + +Both protocol copies then use this state machine: + +1. `feed()` appends buffer views without copying and charges bytes. +2. Drain at most 64 frames or 4 ms. +3. If another complete frame remains, acquire one idempotent decoder pause + epoch and continue with `setImmediate`. +4. Release the pause only when complete-frame backlog and queued bytes fall + below low water. +5. `reset`, handshake `drain`, transport close, and dispose cancel the + continuation and release exactly the epoch they own. + +Main model-pressure mode is the one bounded exception to immediate read pause. +It may classify complete frames into the charged 1 MiB/64-frame data +quarantine while dispatching only eligible control/liveness frames, then +either drains data and token-ordering fences in original order or closes the +provider at the deadline. Exit, recovery completion, and activation cannot +overtake a preceding quarantined frame for the same token. It does not scan +past an incomplete or oversized frame and cannot expand the ordinary decoder +input cap. + +Handshake consumers require the first complete frame synchronously. Preserve +that behavior, then yield before later frames. `drain()` must cancel a scheduled +continuation and return all unread handshake residue in exact byte order so the +next consumer receives it once. + +The decoder permits one advertised valid 16 MiB frame plus 1 MiB input slack. +A partial valid frame keeps reads enabled until that cap; exceeding it closes +the offending transport rather than retaining back-to-back maximum frames. +Oversized payloads are discarded incrementally without full retention. +Sender-side finite PTY bursts and the reserved control lane bound how far a +keepalive/control frame can sit behind PTY data. While paused by this decoder, +the mux suspends both dead-link conjuncts. Resume rebases `lastReceivedAt` and +all outstanding header-ACK timestamps exactly like the existing wake-gap +handler; outgoing keepalives still run. + +In `SshChannelMultiplexer.handleFrame`, clamp header `ack` to +`nextOutgoingSeq - 1` and delete only keys already present in +`unackedTimestamps`. Never iterate a dense integer range toward an untrusted +32-bit value. This remains independent from PTY credit. + +## Cleanup and reconnect + +Every dispatcher client has a generation, and the negotiated session owner has +a separate transferable owner generation. Socket close/error, +`attachClient`/`detachClient`, and dispose invalidate or advance the client +generation atomically. Unexpected disconnect retains the owner generation and +lease through grace; only a proved replacement increments it, and grace expiry +invalidates the lease so a later election starts a new generation. Each +transition: + +- cancel read-pause epochs, writer callbacks, and scheduled work; +- reject queued liveness, control, and ordinary mux frames, clear lane heads, + and reset the four-control fairness counter; +- roll back uncommitted receive-activation leases to their exact prior + active predecessor, drop lease-private data, and await cancellation of only + the provisional token through its originating mux; +- after a validated recovery contract transfers the lease, retain held frames + only in that attempt's bounded quarantine and let cancellation proof or + provider-generation close own failure cleanup; +- on exact exit, seal the private lease, wake its fence, and either admit the + held contiguous prefix or validate cancellation against the highest exact + frame observed before retention/restore decisions; +- fail closed on the exact provider generation when a current recovery cannot + publish cancellation or validate its proof; provisional spawn rollback + failure instead surfaces execution ownership as unavailable; +- retain canceled `restoreRequired` relay deliveries until their response + settlement callback, then delete only the exact still-current record; +- clear or transfer one recovery-completion attempt and its capacity listener; +- move active PTY cursors to reconnect grace or cancel them; +- preserve sealed-unsettled suffixes until the relay applies their ACK, exact + transfer, or cancellation/generation-close proof; +- retry or cancel queued cumulative ACK state without collapsing + `obligationsTerminalEndSu`, `ackQueuedEndSu`, and `ackPublishedEndSu`; +- retain or cancel an exact early-ACK send boundary with its owning token; +- roll back uncommitted desktop reservations and transfer committed + projection IDs before clearing renderer queues; +- cancel uncommitted terminal-fact publications, restore their prior scanner + snapshots, and transfer committed projection scanner state exactly once; +- roll back any remote snapshot replacement before clearing ACK-overflow state; +- preserve partial remote byte watermarks while retaining covering source + frames, and prune cached mappings whose authoritative spans were reclaimed; +- reject and remove exit barriers plus cancellation/preparation ownership on + provider-generation close so late proofs cannot publish final exit; +- close each per-generation model-migration gate after its settlement, remove + its per-PTY fence and timer exactly once, and retain any earlier outstanding + per-PTY fence across an overlapping reconnect; +- on migration-owned callback failure, release only that PTY's admission + charge, timer, and tracked completion before reset/restore; do not close the + shared provider or sibling admissions; +- replace the latest canceled-token record per PTY on ordered cancellation and + clear it on exact next activation, PTY exit, or provider teardown; +- release shared spans no longer referenced; +- recompute native PTY pause state; +- expire pending RPC ownership. + +Unexpected loss of the session-owner generation with active PTY tokens creates +one `reconnect-grace` cursor per PTY for 30 seconds. It retains at most +512 Ki su and 2 MiB charged bytes per PTY; reaching either cap pauses that PTY +instead of dropping more output. A valid owner resume atomically installs the +new owner generation, transfers each cursor to a new token, and returns only +activation and recovery-range metadata. Source-ranged `pty.data` then drains +before the completion fence and live activation. Expiry invalidates the owner +lease, +emits `pty.deliveryCanceled` when possible, releases the gap, resumes the PTY, +and records restore-required/data-gap telemetry. Ordinary subscriber loss or +no-subscriber state outside owner grace retains only the existing replay tail. + +`SshRelaySession.reattachKnownPtys` waits for session-grant readiness and each +PTY's model-migration fence, then runs at most eight attaches concurrently. +Each PTY has its own 10-second attempt deadline and `try/catch`; one failure +cannot abort later PTYs. `notFound` and identity mismatch keep their existing +stale-lease behavior. Other errors are recorded, retried once with bounded +jitter while the same reconnect attempt is current, then surfaced per PTY +without tearing down successful siblings. Time-to-last-reattach is therefore +bounded by waves rather than `N × RTT`. + +Reconnect and replay always create new tokens even when IDs are reused. Old +ACKs and callbacks fail generation/token checks. The attach response declares +the exact checkpoint and recovery end; ordinary source-bearing `pty.data` +proves the gap and the completion fence establishes the live boundary, so main +never double-ingests old obligations. Replace +`SshRelaySession.forwardReattachReplay` with this tokenized intake and delete +`RECONNECT_REPLAY_DUPLICATE_WINDOW_MS`/`shouldForwardReattachReplay`: a +wall-clock fingerprint can suppress legitimate identical output, while the +source checkpoint is authoritative. Exit before reattach may still synthesize +`code: -1` after `notFound`; retaining remote exit tombstones is a separate +behavior change and is not required for the memory bound. + +Recovery receipt is transactional. Main retains quarantined recovery `pty.data`, +the candidate mux, token, checkpoint, and `recoveryEndSu` until the exact +completion fence validates. It commits no partial body to the model. On +failure it requests cancellation only through the candidate mux and accepts +only matching proof; a stale attempt may not touch current mux state. A +quarantine-only attempt may not yet have a main-intake token identity, so +`SshRelaySession` first requires `canceled: true`, finite safe cumulative +ends, `creditedEndSu` equal to the recovery checkpoint, and `sentEndSu` +covering the highest exact-token source range observed privately. Only then is +the intake's no-identity application an intentional no-op; malformed, +under-covering, or checkpoint-mismatched proof fails closed. A +current attempt whose cancellation publication or proof rejects closes the +exact provider generation and its registered resources once, rather than +leaving ambiguous authority. After a successful empty recovery it keeps +`recoveryEndSu` as a live continuity anchor until the first live frame arrives. +A proved recovery failure marks the existing PTY lease detached and retryable +rather than deleting ownership or terminating the physical process. + +For an operation-ID spawn replay, physical result lookup completes first; the +current request then creates and fences a new subscription as specified above. +Disconnect after physical commit/before response leaves the PTY retained but +no stale token. + +PTY shutdown and natural exit cancel native pause state before disposing +node-pty. Natural exit may still leave a charged sealed-unsettled delivery +record; only its native process is gone. Relay disposal generation-closes those +records and clears scheduler/exit timers before walking PTYs. A folder +workspace removal follows the same PTY teardown path; no design step assumes a +Git worktree. + +### SSH producer-pause intent + +Negotiated V1 implements `SshPtyProvider.pauseProducer` and `resumeProducer` +with a token/generation-scoped `pty.setDeliveryPaused` request; window size is +not renegotiated to zero. Relay marks that owner delivery ineligible and pauses +the native PTY only when all required deliveries are ineligible, while another +healthy subscriber may continue. Resume restores eligibility under the +original window. `setPtyBackgrounded` is a separate token-scoped scheduling +hint; it does not itself drop source data or silently convert a lossless model +obligation into keep-tail behavior. + +For V1, desktop pending-cap pressure transfers the recoverable projection and +does not call producer pause. Model-admission or required-lossless pressure and +explicit background policy may call it. Local, daemon, and legacy provider +behavior remains unchanged. Update the provider-interface and IPC comments +that currently assume SSH has an independently bounded pending queue. + +## Budgets + +Every limit has one unit. Source-flow limits use `su`; heap/transport limits use +bytes measured at the point that owns the memory. + +| Resource | High limit | Low/flush point | Action | +| ------------------------------- | -----------------------------------------: | ------------------------: | ------------------------------------------- | +| Legacy publications per client | 2 MiB | 1 MiB | pause affected PTYs; release on drain | +| Legacy publications per relay | 32 MiB | 24 MiB | pause affected PTYs | +| Legacy producer-held PTY frame | 128 KiB | next admission | hold one; pause before another | +| V1 data frame | 16 Ki su target | — | scalar-safe slice/coalesce | +| Encoded PTY frame | 128 KiB | — | reduce source slice before publish | +| Token outstanding credit | 256 Ki su | 64 Ki su newly freed | stop send / eager ACK | +| Sealed-unsettled suffix | token window; 30 s timer per subscriber | ACK/transfer/cancel proof | retain ledger; cancel stalled token | +| Recovery `pty.data` | 16 Ki su target | next turn | normal source lane before completion | +| Reconnect-grace source | 512 Ki su per PTY | — | pause at cap | +| Retained live data per PTY | 2 MiB | 1 MiB | pause source owner | +| Retained live data per relay | 64 MiB | 48 MiB | pause affected source owners | +| Replay tail | existing 100 Ki su × 50 PTYs | — | source-range trim; bytes charged globally | +| Liveness/control writer reserve | 25% of high water, capped at 64 KiB | drain | producer lanes cannot consume | +| Minimum PTY sink capacity | 8 KiB non-reserved empty | — | reject PTY subscription | +| Metadata control response | 64 KiB | — | body must use producer stream | +| Control queue | 256 frames / 1 MiB | drain | close subscriber; owner reconnect | +| Reshapable bulk producer frame | current non-reserved sink capacity | next frame | slice, admit, recheck priority | +| Fixed filesystem frame | existing 256 KiB raw payload | empty producer/sink epoch | admit one unchanged, then await settlement | +| Decoder | 16 MiB frame + 1 MiB slack | no complete backlog | pause/close at hard cap | +| Decoder turn | 64 frames or 4 ms | next turn | `setImmediate` | +| Header-ACK timestamp entries | 4095 + 1 reserved | ACK/resume | stop ordinary writes; coalesce liveness | +| Main receive-activation hold | 256 Ki su / 2 MiB per token; 64 MiB total | recovery completes | pause aggregate; close provider on cap | +| Main model admission per PTY | 256 Ki su / 2 MiB | 128 Ki su / 1 MiB | pause mux admission | +| Main model admission global | 12.5 Mi su / 64 MiB | 8 Mi su / 48 MiB | pause mux admission | +| Main blocked-intake slot | one 128 KiB frame | model low water | hold blocked frame | +| Main pressure control reserve | 1 MiB / 64 frames | 10-second close deadline | quarantine data; service control | +| Main model migration fence | 10 seconds | — | reset generation / restore required | +| Main desktop in-flight | existing 512 Ki su per PTY / 8 Mi su total | existing lows | transfer/restore policy | +| Lossless remote send ledger | 2 MiB/stream, 16 MiB global | 1 MiB/12 MiB bytes | stop send; explicit detach transfers/closes | +| Activation/exit/owner grace | 30 seconds | — | token cancel/gap policy | + +Retained strings are charged once as +`max(Buffer.byteLength(value, 'utf8'), 2 * value.length) + 128`; encoded buffers +use exact `Buffer.byteLength`; ledger/cursor entries charge 128 bytes.

Do not add max-lines disables, generic helper modules, +native dependencies, or a per-file lint exception. + +## Tests + +The checklist below is the normative matrix, not a claim that every physical +topology or the current shared-worktree diff ran. Implemented seams and prior +recorded evidence include: + +- shared session negotiation, grant publication, stale-owner recovery, source + ledger, ACK queue/publication separation, and cancellation proof contracts; +- relay writer admission/drain/liveness, zero-display source publication, + operation-ID retry activation, fixed-size filesystem compatibility, + capacity-aware Git/PTY slicing, decoder caps, and token rotation; +- main model admission, desktop identity/rollback, exit barriers, remote + reserve/commit/rollback, token cancellation, exact recovery continuity, + eight-wide reconnect, retention budgets, unconditional negotiation, and + deployment; +- current-working-tree restore-response retirement, fail-closed recovery cancellation, + partial remote ACK, higher-generation token rotation, reclaimed-span + idempotence, three-lane mux fairness, provisional claim gating, and + generation-fenced exit proof ordering plus bounded exact generation closure; +- the four-test Docker OpenSSH/deployed-relay suite for source-window plateau, + concurrent typing, fixed-size filesystem/Git churn, and owner reconnect. + +The earlier rebased checkpoint at +`38fbf3520741ce4ccd86410f7cea9ff8217a7834` passed: + +- frozen dependency setup, full lint, full typecheck, `git diff --check`, and + the 52-gate reliability manifest validation; +- all Linux, macOS, Windows, and WSL relay build targets plus + `electron-vite build --mode e2e`; +- 24 focused SSH/source-credit files with 354 tests; +- 14 watcher/daemon/package/glibc-adjacent files with 409 tests; +- a 57-file deterministic changed-surface sweep with 1,186 tests; +- the joined renderer/headless snapshot seam with 59 tests and its broader + focused slice with 180 tests; +- the relay recovery and fixed-size filesystem/Git slice with 105 tests. + +That checkpoint's Docker OpenSSH/deployed-relay run passed all four tests in 1.0 minute: +direct typing median/worst was 107.7/113.6 ms; ACK-stalled typing was +3.6/107.3 ms at an exact 262,144-source-unit plateau; fixed-size filesystem/Git +churn was 148.1/161.1 ms with 93 bulk reads; owner reconnect completed in +15.7 seconds. These measurements are direct SSH/deployed Linux relay evidence +only. + +The four-case Docker results predate the final adversarial lifecycle +reconciliation and are not current-head proof for those races. On the earlier +working tree, a deterministic test reproduced recovery completion becoming +visible at source unit 4 while lease-held recovery ended at 8. After the +validated contract began private quarantine ownership before awaiting the +body, seven provider/session files passed 94 tests and the isolated deployed +Linux relay/direct-SSH reconnect case passed in 17.7 seconds with 256 recovery +frames plus post-reconnect terminal/filesystem proof. Against the same +private-transfer artifact, the final four-case run passed in 1.1 minutes: +direct typing was 6.2/7.4 ms median/worst; ACK-stalled typing was 5.5/16.3 ms +at exactly 262,144 held source units; fixed-size filesystem/Git churn was +141.2/151.5 ms with 95 bulk reads; reconnect completed in 16.0 seconds. All +other live topologies remain separate. + +After the exact-PTY migration-failure containment fix and current-main merge, +`electron-vite build --mode e2e` and `pnpm run build:relay` produced the exact +artifact hashes recorded above. The four-case Docker command then passed in +56.7 seconds without a source-credit override: direct typing was 5.3/108.9 ms +median/worst; ACK-stalled typing was 4.8/107.6 ms at exactly 262,144 held source +units; fixed-size filesystem/Git churn was 152.0/173.3 ms with 84 bulk reads; +reconnect completed in 14.3 seconds. This is direct SSH/deployed Linux relay +evidence only. + +At the implementation commit above, the source/intake slice passed 12 files and 205 +tests, the provider/session slice passed 16 files and 192 tests, and this +complementary lifecycle slice passed 13 files and 150 tests: + +```bash +pnpm exec vitest run --config config/vitest.config.ts \ + src/relay/relay-pty-source-restore-retry.test.ts \ + src/main/ssh/ssh-relay-session-recovery-races.test.ts \ + src/main/runtime/rpc/terminal-source-range-ledger.test.ts \ + src/main/runtime/rpc/terminal-multiplex.test.ts \ + src/main/ssh/ssh-multiplexer-transport-writer.test.ts \ + src/main/ssh/ssh-channel-multiplexer-backpressure.test.ts \ + src/main/providers/ssh-pty-notification-routing.test.ts \ + src/main/providers/ssh-pty-source-delivery-ledger.test.ts \ + src/main/ssh/ssh-pty-retired-source-deliveries.test.ts \ + src/main/providers/ssh-pty-provider-agent-session-create-operation.test.ts \ + src/main/providers/ssh-pty-provider-exit-race.test.ts \ + src/main/ipc/ssh-pty-output-exit-deadline.test.ts \ + src/main/ipc/ssh-pty-remote-source-range-consumers.test.ts --reporter=dot +``` + +The deterministic recovery seam specifically covers an empty recovery followed +by a gapped live frame, overlapping reconnect attempts, late frames after +cancel, exact exit during private recovery, stale-transfer rollback authority, +capacity-rejected and post-restore proof watermarks, typed stale-owner retry, +response-settled `restoreRequired` retirement, completion arriving before +lease-held body frames, and fail-closed exact-generation cleanup. A separate +10,000-rotation oracle proves canceled-token retirement remains one record per +PTY. Transferred recovery data remains private until body/fence validation, +and a proved token-local failure causes no physical PTY shutdown, ownership +delete, or lease expiry. +The model-migration failure oracle uses two PTYs in one provider generation: +one raw callback rejects under an active fence, returns +`checkpointUnavailable`, resets one model, and releases its charge and timer; +the sibling checkpoint, provider mux, filesystem/Git transport, and another +provider generation remain live. A paired admission oracle proves the same +failure without an active migration still closes the generation and rejects +its sibling receipt. +The remote-consumer seam covers partial cumulative ACK, safe higher-generation +token rotation, and token cancellation followed by late detach/replacement +commit, proving reclaimed span IDs reject commit, preserve rollback ownership, +and are then cleaned up idempotently. + +### Normative unit and property matrix + +- accept monotonic cumulative ACKs and reject duplicates, regressions, + over-credit, invalid numbers, wrong clients, wrong PTYs, and stale tokens; +- prove with generated span/ACK sequences that + `sentEndSu - creditedEndSu <= windowSu`; at `window - 1`, slice a + splittable frame to one source unit and hold an indivisible transform; +- generate merge, split, remainder, salvage, thinning, empty-transform, and + interactive-bypass queue operations and prove ledger conservation; +- split DEC mode 2031 subscribe and withdraw sequences across chunks, then + inject pending-cap salvage, rollback, transfer, reconnect, and source gaps; + prove fact order, exact scanner restoration/reset, no duplicate reply, and no + source settlement from projection metadata; +- put two clients at different display/source offsets in one shared span and + prove no resend, skip, or early reclamation; +- cover ASCII, BMP/CJK, surrogate pairs, unpaired surrogates, JSON-escaped + controls, and transformed spans where `rawLength !== data.length`; assert the + budget arithmetic and reject transformed frames without valid `rawLength`; +- run the shared semantic state-machine suite and the implemented SSH + socket/named-pipe adapter suite; local and daemon V1 adapters remain + unimplemented, direct-stdio/WSL has deterministic common-transport evidence + only, and remote-runtime source mapping is implemented at a deterministic + seam but unexecuted in a live paired topology; +- verify every new SSH session and reconnect offers V1 and every same-build + relay advertises and grants it; separately verify a capability-omitting old + client remains token-free and the narrow method-not-found relay fallback is + bounded; cover invalid/stale credential or lease rejection, 30-second lease + expiry, and atomic reconnect generation transfer through POSIX sockets and + Windows named pipes; prove constructor stdout, WSL child stdio, and an + unproved plain socket are never elected, and cover POSIX `0600` plus Windows + current-user ACLs; +- verify split shell/SFTP home discovery, per-launch marker creation under the + held install lock, credential write before lock release, canonical shell-path + fallback, system-SSH bypass, and unconfirmed teardown lock retention; +- verify token rotation on spawn, attach, reconnect, provider replacement, and + same-client duplicate attach/spawn; replacement must cancel the old token + once, report its exact remaining span, and transfer only matching recovery + coverage while canceling the already-checkpointed prefix without re-ingest, + duplicate output, or an open cursor; +- keep one lossless remote stream attached across an unsettled old-token frame + and a contiguous new-token frame; require strictly higher client and owner + generations, the same provider/incarnation, a new token, and reject every + stale or partially advanced identity; +- verify metadata response callbacks precede source-ranged recovery and live + data in V1, including saturation with older control; use multi-frame + all-control-character gaps to prove source bodies remain ordinary + producer-owned `pty.data` rather than control responses; +- feed response, recovery, completion fence, and first live data in one decoder + turn; prove synchronous `beforeResolve` installs a provisional cursor at + `checkpointSourceEndSu`; deliver completion before lease-held frames, then + prove validated reconnect transfers those frames only into private + quarantine, routes ranges through `recoveryEndSu`, and projects them once + only after exact body/fence validation.

The test harness exercises the +normal deployment and connection path with no override and: + +1. stalls desktop ACK and observes an exact 256 Ki-source-unit negotiated + plateau while a second SSH PTY remains responsive; +2. preserves fixed `STREAM_CHUNK_SIZE` filesystem semantics and completes Git + churn without corruption while active typing stays within budget; +3. reconnects the negotiated owner lease and proves the existing SSH + workspace terminal remains usable; +4. retains the direct typing latency control. + +Writer `write(false)`/drain, callback failure, liveness bypass, decoder +scheduling, sealed exit, stale ACK, exact recovery, and remote replacement are +proved at deterministic unit/service seams. The Docker suite does not force +the main-to-relay sink to remain saturated beyond the health deadline, does +not prove paired-runtime behavior, and must not be cited for those claims. + +Docker SSH proves the Linux SSH provider/relay path only. It must never be +reported as headed paired-server, headless `orca serve`, remote-runtime +lossless subscription, macOS node-pty, Windows ConPTY/named pipe, or WSL +evidence. + +The Slice 5d mapping is implemented, but live paired-runtime coverage remains +a separate promotion requirement: + +| Topology | Required oracle | +| ---------------------------------------------- | ------------------------------------------------------------------------------------------- | +| Headed paired desktop server + separate client | host-owned PTY identity, source mapping, client ACK/restore, reconnect, and cleanup | +| Headless `orca serve` + same client flow | identical source settlement plus headless model admission/startup ownership | +| Direct Docker SSH | deployed relay transport, main desktop intake, real remote process, writable/drain behavior | +| WSL child stdio | sentinel/residue, read pause, writer drain, no POSIX-path assumptions | +| Windows native | ConPTY pause/resume and named-pipe callbacks/drain | +| Local daemon | authenticated paired hello and exact-version legacy fallback | +| Local provider | direct semantic instantiation with no relay framing | + +Each topology also runs in a folder workspace fixture with no `.git`; source +identity and cleanup never depend on worktree metadata. Prior-version daemons +remain version-scoped legacy processes: report them, do not negotiate V1, +adopt their PTYs, or claim the new main bounds their memory. Keep any new +native artifact compatible with Ubuntu 20.04/glibc 2.31; this design itself +adds none. + +The +`terminal-performance.output-backpressure-budget` reliability gate remains +`experimental` and `partial`. Its `coveredProviders: ["ssh"]` means the +deterministic direct-SSH contracts plus the macOS-hosted Docker +OpenSSH/deployed-relay run described above. It does not cover every SSH host +platform and does not mark local, daemon, remote-runtime, headed, headless, +WSL, Windows, folder-workspace, prior-version, mixed-version, or Ubuntu 20.04 +packaging topologies as executed. The WSL stdin write/callback/drain contract +is deterministic adapter evidence only, not a physical WSL run. + +## Compatibility and release validation + +Every new SSH session and automatic reconnect offers V1. Every relay from the +same build advertises and grants V1, so the normal deployment path always uses +source credit. Sink drain, the reserved writer lane, stdout serialization, +bounded decoder work, bulk admission, and hostile header-ACK hardening are +also unconditional. + +Compatibility behavior is explicit: + +1. An old client that omits the V1 capability remains token-free and uses the + bounded legacy writer. +2. A new main may use bounded legacy delivery only when the same-build + compatibility check accepts JSON-RPC method-not-found for + `pty.openClient`. +3. A successful `pty.openClient` response without the offered V1 grant, an + invalid grant, or another request error fails closed rather than silently + downgrading. +4. Disconnect performs normal token-scoped cancellation and exit cleanup; it + never rotates a live V1 token into legacy mode in place. +5. A prior-version orphan remains governed by its own version-scoped binary and + cleanup. The new main reports but does not adopt, kill, or claim to bound it. + +Implementation and validation status: + +1. Slices 1-4 are implemented under legacy-compatible framing with narrow + reliability oracles. +2. Slices 5a-5c implement unconditional V1 offer/advertisement, source credit, + exit, and reconnect with unit/service contracts and direct Docker SSH + evidence. +3. Slices 5d-5e implement remote source-range transactions and the final + lifecycle reconciliation at deterministic main/runtime/provider/relay + seams. Live headed paired, headless, WSL, Windows, local-daemon, + local-provider, and folder-workspace evidence remains future work before + those topologies are marked covered. +4. Current-working-tree deterministic reconciliation and focused integrated-fix checks + are complete. The isolated reconnect and final four-case direct-SSH Docker + runs, full repository typecheck, and full lint/reliability suite are green; + final exact-implementation-head architecture and transport reviews found no + code blocker, and the transport review's stale-provenance finding is closed + by the exact artifact record above. + +Release criteria: + +- no unbounded increase across 30-minute desktop-only, slow-model, and required + lossless-consumer floods; +- relay and main stay within the documented budgets plus 25% allocator slack; +- active echo p95 remains below 100 ms under a background flood; +- exact logical output sequence after resume; +- no leaked obligations, writer callbacks, drain waiters, cursors, tokens, + decoder tasks, or paused PTYs; +- no false dead-link reconnect across a 30-minute saturated/self-paused run; +- bounded time-to-last-reattach with one injected per-PTY failure; +- unconditional same-build V1 negotiation, bounded legacy compatibility, + manual mismatch rejection, orphan reporting, and Linux/macOS/Windows/WSL + smoke tests pass. + +## Calibrated findings and non-goals + +- The liveness risk is real for transport saturation and self-paused decoding. + A renderer-only stall is absorbed by bounded projection transfer/restore + while required-model credit continues. A stalled model admission or + negotiated lossless remote consumer exhausts its window and pauses the + native PTY; tests keep these distinct. +- V1 uses logical priority lanes and reserved writable capacity, not a second + SSH channel. Adding a physical control channel would widen handshake, + reconnect, system-SSH, and legacy compatibility scope without being required + once PTY bursts and decoder pauses are bounded. +- There is no arbitrary 16-socket cap. Additional PTY projections are bounded + and isolated by their own writer/publication capacity; short-lived remote CLI + clients remain independent. +- A 60-second watchdog may warn about an old open obligation, but it cannot + force-credit data. Recovery must use a proven transfer or token cancellation. +- Reconnect-grace data is a bounded live-delivery owner, not an expansion of the + 100 Ki replay-tail contract. Expiry is an explicit data gap, never silent + truncation. +- Content-hashed endpoints make mixed production binaries unreachable. The + real upgrade skew is an orphaned prior-version daemon outside the new main's + startup-gated endpoint; V1 reports but cannot adopt, cancel, or retroactively + bound it. +- Preserving the real exit code for a PTY that exits before any new client + reattaches would require attach-visible tombstone retention. V1 documents and + tests the existing synthetic `-1` fallback instead of coupling that separate + product change to backpressure. + +## Reference-commit assessment + +Retain from `1500a92904` the useful concepts of generation tokens, client +isolation, pause/resume, targeted dispatcher sends, cleanup of stale credits, +and slow-client eviction. + +Do not reproduce these behaviors: + +- ordinary notifications continuing to write after `write(false)`; +- delta ACKs without cumulative token scope; +- automatic live broadcast to every connected client; +- force-flushing final PTY output beyond the credit window; +- per-client windows without aggregate retained-memory budgets; +- synchronous all-frame draining; +- assuming `256 Ki × 50 PTYs × N clients` is itself a safe memory bound. + +This design makes writable-drain state, application credit, retained memory, +and decoder CPU four explicit and independently enforced bounds. + +## Platform and workspace requirements + +The relay can run on a native macOS, Linux, Windows, or WSL host reached over +SSH. Use Node stream APIs and runtime platform checks; do not assume POSIX file +descriptors, path separators, signals, or Unix sockets. Windows uses ConPTY and +named pipes, while POSIX uses node-pty and Unix sockets, but both must expose +the same idempotent pause/resume and sink state contract. + +Network latency changes ACK cadence but not the window invariant. A +high-bandwidth/high-latency SSH link may need later window tuning based on +telemetry; it must not receive an unbounded adaptive window. SSH disconnects +are normal lifecycle events, not exceptional shortcuts around cleanup. + +No part of subscription identity or cleanup may depend on `.git`, a worktree +ID, or a Git provider. Folder workspaces use the same connection, PTY, and +client generations as Git worktrees. Bulk Git changes only slice and schedule +existing response frames; they add no Git command, provider-specific behavior, +or requirement beyond the Git 2.25 core-workflow baseline. diff --git a/docs/readme/README.es.md b/docs/readme/README.es.md index e29c91a79720..0a1ca5390ac5 100644 --- a/docs/readme/README.es.md +++ b/docs/readme/README.es.md @@ -36,7 +36,7 @@ Supervisa y dirige a tus agentes desde el teléfono — recibe una notificación cuando un agente termine y envía instrucciones de seguimiento desde cualquier lugar. -[App Store de iOS](https://apps.apple.com/us/app/orca-ide/id6766130217) · [APK para Android](https://github.com/stablyai/orca/releases/download/mobile-android-v0.0.31/app-release.apk) · [Docs →](https://www.onorca.dev/docs/mobile) +[App Store de iOS](https://apps.apple.com/us/app/orca-ide/id6766130217) · [APK para Android](https://github.com/stablyai/orca/releases/download/mobile-android-v0.0.32/app-release.apk) · [Docs →](https://www.onorca.dev/docs/mobile) @@ -227,7 +227,7 @@ yay -S stably-orca-bin Vincúlala con tu app de escritorio para supervisar y dirigir a tus agentes desde el teléfono. - **iOS:** [Descargar desde App Store](https://apps.apple.com/us/app/orca-ide/id6766130217) -- **Android:** [Descargar el APK](https://github.com/stablyai/orca/releases/download/mobile-android-v0.0.31/app-release.apk) +- **Android:** [Descargar el APK](https://github.com/stablyai/orca/releases/download/mobile-android-v0.0.32/app-release.apk) --- diff --git a/docs/readme/README.fr.md b/docs/readme/README.fr.md index a6e4e50b773b..ddbf633b3211 100644 --- a/docs/readme/README.fr.md +++ b/docs/readme/README.fr.md @@ -3,7 +3,7 @@

Pin the relocated symbols (the fix).** +[`config/patches/node-pty@1.1.0.patch`](../../config/patches/node-pty@1.1.0.patch) +adds a `.symver` shim in `src/unix/pty.cc` that binds `openpty`, `forkpty`, and +`pthread_sigmask` to their pre-merge version node — `GLIBC_2.2.5` on x64, +`GLIBC_2.17` on arm64 (each architecture's baseline glibc). glibc still ships +those as compatibility aliases, so the reference resolves on both new build hosts +and old targets. + +The catch: gcc defaults to `--as-needed` and, since the pinned symbols now +resolve from libc's compat aliases at build time, it drops `libutil`/`libpthread` +from `DT_NEEDED`. On the target those libraries are where the symbols actually +live, so the patch's `binding.gyp` `ldflags` force +`-Wl,--no-as-needed,-l:libutil.so.1,-l:libpthread.so.0` back into `DT_NEEDED`. +The shim is guarded by `#if defined(__linux__)`; macOS and Windows are untouched. + +**2. Gate packaging (the regression guard).** +[`config/scripts/verify-linux-glibc-floor.cjs`](../../config/scripts/verify-linux-glibc-floor.cjs) +runs in the electron-builder `afterPack` hook for Linux. It reads every bundled +native binary's version needs (`objdump -p` "Version References" — the +authoritative load-time list, which also captures symbol-less markers like +`GLIBC_ABI_DT_RELR`) and fails the build if any strong `GLIBC_`/`GLIBCXX_`/ +`CXXABI_` node is newer than stock Ubuntu 20.04 provides, naming the file and the +offending node. Weak needs are ignored (the loader tolerates them). It also +asserts the flip side of the `.symver` fix: any binary that imports +`openpty`/`forkpty` must keep `libutil.so.1` in `DT_NEEDED` — otherwise the +pinned `openpty@GLIBC_2.2.5` resolves from libc's compat alias at build time (so +the version check passes) yet fails to load on 20.04, where those functions live +only in libutil. A future runner bump, a new native dependency, or a dropped +ldflag therefore fails the release build instead of shipping a Linux app that +crashes on launch. + +> The gate is a static invariant, not an integration test.

Each wave refreshes every target repo and then lineage. Because the next preparation starts after the previous one settles, the existing in-flight repo coalescer does not collapse these sequential scans. Simultaneous targets multiply the work, while disconnect handling separately calls the single-tab `clearTabPtyId` action once per live tab. + +Replace this with host-qualified, epoch-fenced provider reads and a renderer coordinator with two distinct modes: + +- reconnect finalization retries the exact target's terminal panes immediately, before optional discovery; +- preparation-only refreshes the exact target's catalog, worktrees, and lineage without remounting panes. + +Main owns one provider-incarnation authority per direct SSH target. It is a strict composition of the existing `connectionGeneration` and a new opaque `providerEpoch`: one helper rotates both atomically on the same transition set, and provider work carries and compares the pair. Existing file-mutation fencing continues to carry `connectionGeneration`, but it now advances on every provider-invalidating transition too; reconnect recovery cannot advance one clock without revoking the other. Every authoritative request carries the exact execution host and captured authority through preload to main; main selects the provider by that complete identity and revalidates the authority before any durable side effect. Renderer preparation deduplicates only overlapping work with identical concrete inputs. A completed preparation is not cached for the lifetime of an authority. + +Direct SSH provider calls use a dedicated fair limiter with five local slots, explicit deadlines, and cancellation. Cancel acknowledgement means local waiter settlement; the existing fire-and-forget `rpc.cancel` does not acknowledge relay-handler completion. A separate cancel-debt allowance bounds replacement admission while relay work may be finishing. The five-slot bound applies only to locally unsettled detected-worktree provider calls submitted by this coordinator; aggregate telemetry reports the late-work allowance and other same-relay traffic separately. Runtime discovery, sidebar refreshes, filesystem events, catalog reads, and lineage reads retain their own concurrency behavior and are measured separately. + +This remains separate from the sidebar fix in `9d3ae3adc7`, which does not own `ssh:state-changed`, remote-workspace preparation, or terminal binding cleanup. + +## Goals + +- Recover terminal panes without waiting for Git discovery on the same or another target. +- Keep coordinator-owned direct SSH provider work bounded and fair across targets. +- Make provider selection correct when repo IDs collide across local, direct SSH, and remote-runtime hosts. +- Reject obsolete provider results before any main or renderer authoritative mutation. +- Preserve final-state convergence for later same-connection remote snapshots and wake refreshes. +- Keep disconnect and retry scope symmetric across Git worktrees and folder workspaces. +- Preserve relay reattach identifiers and terminal/session recovery semantics. +- Make timeout, cancellation, non-authoritative data, and operational failure separately observable without exposing identifiers. + +## Non-goals + +- Changing SSH credentials, backoff policy, or user-facing reconnect controls. +- Moving runtime-owned work into the direct SSH coordinator. +- Changing the component-scoped sidebar refresh queue added by `9d3ae3adc7`; the shared detected-worktree provider coalescer does gain lease accounting. +- Expanding remote-workspace serialization to folder workspaces. +- Changing Git commands, worktree parsing, or Git capability detection. +- Changing the remote-runtime wire protocol. +- Establishing a renderer-wide or application-wide provider-call ceiling. + +## Current flow and root cause + +### Connected path + +`applySshConnectionStateChange` currently: + +1. filters `store.repos` by raw `connectionId`; +2. calls `Promise.all(remoteRepos.map(fetchWorktrees))`; +3. calls `fetchWorktreeLineage`; +4. scans target worktrees and bumps terminal generations one worktree at a time; and +5. calls `syncRemoteWorkspaceAfterConnect`. + +`syncRemoteWorkspaceAfterConnect` calls `prepareRemoteWorkspaceTarget`, repeating repo and lineage refresh. A nonempty snapshot then reaches `applyRemoteWorkspaceSnapshot`, which prepares a third time. + +For a target with `R` repos, the connected path therefore performs `2R` detected-worktree scans and two lineage reads without a snapshot, or `3R` scans and three lineage reads with one. The existing detected-worktree single-flight joins only requests whose provider reads overlap. These preparation waves are sequential in the current call chain, so it does not collapse their scan count. Other overlapping callers can still join a scan; telemetry must measure observed calls rather than infer a global `kR` multiplier. + +### Disconnect path + +Terminal failure states walk repo-derived worktrees and call `clearTabPtyId(tab.id)` for each tab whose `ptyId` is present.

Coordinator routing defaults on and can be disabled per build with `VITE_DIRECT_SSH_RECONNECT_COORDINATOR=false` or per renderer session with `orca.directSshReconnectCoordinator.enabled=false`; the fallback retains host/authority fencing, atomic terminal recovery, and bounded preparation. + +Deterministic validation on the final rebased implementation passed all 42 changed unit suites (1,960 tests), including the 11-file direct-SSH terminal gate (637 tests), the 11-file renderer provider/transport gate (763 tests), and the 12-file main/preload/runtime/shared authority gate (513 tests), plus full typecheck, changed-code quality, reliability-gate and max-lines checks, `git diff --check`, and an Electron E2E-mode build. The authority gate proves retained SSH connection and detected-port payload admission is wired into native preload and runtime-client/environment production routes. An earlier full `pnpm test` exercise ran 3,707 files and 39,083 tests; only two assertions in unchanged `agent-exec-handler.test.ts` failed because the managed terminal already injects `GIT_CONFIG_*` prompt settings.

Main is the sole issuer of `SshProviderEpoch` and `connectionGeneration`. Renderer never increments, orders, parses, or synthesizes either value. +2. Direct SSH state is normalized to `providerEpoch: SshProviderEpoch | null` plus `connectionGeneration?: number`. Main-originated direct SSH state always carries a valid pair. `null` or a missing generation means unknown authority, not zero and not a renderer fallback. +3. A single `rotateSshProviderAuthority(targetId)` helper advances both values atomically before every provider-invalidating transition: new connect ownership, transport replacement or loss, relay/multiplexer replacement or loss, provider disposal, target readoption/reassignment, and permanent target removal. No producer may rotate or publish only one component. +4. `connectionGeneration` remains the existing SSH mutation expectation. Expanding its rotation set closes relay-only mutation races. Provider/reconnect operations compare the full `(providerEpoch, connectionGeneration)` pair; this is the formal composition rule, not two independent clocks. +5. Main registers the provider serving the new pair before broadcasting `connected`. A broadcast-first transition is invalid because it can start a preparation against an unregistered provider with no guaranteed self-heal event. +6. Renderer partial state writers are patches. They preserve both main authority fields and cannot author a `connected` state with a new value. +7. Every boundary that decides equality, copies state, admits retained state, preloads state, reconciles state, or republishes state must preserve both fields. This inventory includes `sshConnectionStatesEqual`, `admitSshConnectionState` and its byte/range checks, public-state projection, `ssh:getState`, `ssh:state-changed`, startup reconnect, runtime-client retained payloads, renderer/runtime SSH state stores, web-file mutation reads, and all fixtures/builders. Allowlisted clones must name both fields; equality treats either field changing as significant. +8. A recovery operation captures one exact `DirectSshAuthority = (targetId, providerEpoch, connectionGeneration)`. Equality is the only permitted authority operation. +9. If a connected event lacks either component, the renderer performs one bounded `ssh:getState` reconciliation with a per-target arrival watermark. The reply may fill authority only if no newer push event arrived and the stored event/status still matches the initiating event; it cannot transition status or resurrect an older `connected` state. If authority remains unknown, authoritative preparation, retry, sync, and snapshot mutation fail closed with `authority-unknown`; disconnect cleanup remains allowed. +10. After every await and inside every authoritative store updater, current state must still name the same connected target and exact authority pair. +11. Supersession is determined by coordinator arrival order and exact equality, never numeric ordering. +12. On any authority change, before new preparation admission, cancel the target's queued work, locally settle obsolete waiter leases, send exactly one cancellation for every affected in-flight provider request ID, mark all late results stale, and retain main-side post-await fences. Terminal finalization for the new authority does not wait for old relay work. +13. Exhausting one target's per-session generation counter rolls the process generation scope and revokes every direct SSH target, not only the target that exhausted its counter. Main invalidates every cached authority and aborts every registered provider request from the old scope before any target can publish or admit work under the new scope. + +### Host-qualified ownership + +1. Direct reconnect work owns only `toSshExecutionHostId(targetId)`. +2. Every coordinator detected-worktree provider invocation carries `(repoId, executionHostId, expectedAuthority, providerRequestId)`. Each renderer consumer separately owns a `waiterLeaseId`; a lease ID never crosses IPC or names provider work. +3. Main resolves a repo by the complete `(repo.id, executionHostId)` identity only after validating all present repo provenance. `executionHostId` and legacy `connectionId` must agree when both are present; a catalog row for which either source names the requested host while the other names another SSH, local, or runtime host makes the host catalog non-authoritative. Zero, contradictory, or multiple matches fail closed. Main never uses explicit-field precedence to hide a contradiction and never falls back to first-match `getRepo(repoId)` for a host-qualified request. +4. A local host request can select only a local repo. A direct SSH host request can select only the matching target/provider. A runtime host is rejected by the desktop handler and must use the existing runtime RPC route. +5. A successful response uses a local or direct-SSH discriminant. The direct-SSH variant cannot be constructed without the resolved execution host and full authority pair. Renderer validates the wire discriminant and rejects a mismatch before any use. +6. Runtime-owned or runtime-transported worktrees remain under the runtime environment scheduler, including SSH execution hosts whose `runtimeOwnerEnvironmentId` names a HUB. +7. Raw repo IDs, paths, UI focus, and unqualified legacy metadata are not ownership evidence. Pre-catalog scope resolution uses explicit worktree/repo provenance and `getExplicitRuntimeEnvironmentIdForWorktree`; it must not use the focused-runtime fallbacks in `getExecutionHostIdForWorktree` or `getRuntimeEnvironmentIdForWorktree`. `runtime:unresolved-owner` and focus-only results are ambiguous, not another host's. Unknown ownership is diagnostic and retryable, but never authoritatively replaced or deleted. +8. All present provenance must agree. Explicit worktree ownership takes precedence only after agreement is proven; repo-derived ownership is a fallback only when explicit worktree ownership is absent. A worktree stamped `ssh:B` with repo-derived `ssh:A`, or any direct-SSH row with an explicit runtime owner, is `contradictory-owner` and is preserved without refresh, merge, retry, or pruning. + +### Merge fencing + +1. Provider results are immutable until all host and authority checks pass. +2. Main revalidates the request host, provider instance, and exact authority after the provider await and before: + - remembering worktree roots; + - pruning persisted lineage; + - stamping or backfilling worktree metadata; or + - returning an authoritative result. +3. Renderer revalidates immediately after the preload/runtime await and before any use of the result, including: + - `routeListingBranchSwitchesThroughGitIdentity`; + - hosted-review sanitation; + - `updateWorktreeGitIdentity`; + - `buildWorktreePurgeState`; + - `worktreesByRepo` or `detectedWorktreesByRepo` merges; and + - best-effort lineage refresh. +4. Host-scoped catalog and lineage snapshots are revalidated before their sole renderer merge. +5. A remote-workspace token and snapshot revision are revalidated after hydration and immediately before session merge/publish. The merge also preserves any terminal-recovery revision newer than the snapshot operation. +6. Stale, superseded, timed-out, and canceled results perform zero authoritative mutations and are not logged as operational errors. + +### Terminal state + +The disconnect action preserves the current call-site predicate: a tab is affected only when `tab.ptyId != null`. A tab without a `ptyId` remains byte-identical even if it has `pendingActivationSpawn` or an inconsistent auxiliary PTY index. + +For each affected tab, the atomic action must: + +- set `tab.ptyId` to `null`; +- empty its `ptyIdsByTabId` entry; +- consume `pendingActivationSpawn`; +- remove pending Codex restart and restart-notice entries for the cleared live PTY; +- preserve `lastKnownRelayPtyIdByTabId` for relay-grace reattach and the `#9911` orphan-safety invariant; and +- leave layouts, deferred SSH sessions, pending reconnect IDs, suppression/shutdown guards, tab IDs, titles, generations, and agent state unchanged. + +The action must not bump activity, sort worktrees, or persist worktree metadata. A repeat after all qualified bindings are clear returns the original store state. +It also must not emit `session.tabs.close`, `session.tabs.closeLifecycle`, provider shutdown, or process signals. Binding loss is not close intent, tab retirement, or proof that a PTY died. + +Reconnect finalization must: + +- use `shouldRetryPaneSpawnOnSshReconnect`; +- include exact direct SSH Git-worktree and folder-workspace keys; +- run synchronously before catalog or provider awaits; +- treat a non-null `ptyId` as live only when transient binding provenance names the current authority and the current tab-wide spawn/reattach attempt has established live authority; +- clear stale binding evidence from a missed disconnect or prior authority before testing retry eligibility; +- keep at most one tab-wide retry attempt in flight per tab and authority; +- join renderer pending-spawn promises only for the same retry attempt; authority or tab-generation advance starts independently, and a late obsolete fresh PTY is rejected and retired; +- accept a spawn or reattach acknowledgement only when its attempt, authority, tab generation, target-qualified PTY, and committed PTY index all match; the first split success establishes the tab fallback and a live continuation lease, and later or post-success-mounted siblings capture and commit through that exact lease without replacing the fallback; +- admit a reattach identity before publishing renderer PTY handlers; revalidate the captured lease after every asynchronous SSH preparation wait and, after the synchronous already-exited delivery case, before error or launch-metadata publication, deferred-state mutation, binding cleanup, or replacement spawn; drop stale owned handlers without killing the durable PTY a current lease may adopt; +- settle retirement of a newly created session-expired fallback when admission rejects it, including after transport destruction, and surface shutdown refusal as unknown, without killing a rejected reattach or cold restore that another current lease may adopt; +- preserve the continuation lease if its primary PTY exits while another split leaf from the same attempt is still activating, then promote the late sibling when it commits; +- on an attempt-one sibling failure or timeout, revoke that attempt and rotate the whole tab once; after attempt two is exhausted, retain its continuation lease for siblings already settling while forbidding attempt three; +- when a split pane detaches to a new tab, project the same exact live or pending authority and retry history to both resulting tabs, including a bound-plus-unbound split or an all-null continuation gap before any leaf binds; the detached null-PTY tab remains activation-pending, and a rejected acknowledgement or detach returns the original relevant maps unchanged; +- permit a tab hydrated, newly discovered, or left unbound after a failed spawn to receive a bounded same-authority corrective bump; +- update all affected workspace buckets in one Zustand publication; and +- leave preparation-only requests, nonqualifying tabs, and every other host unchanged. + +The coordinator keeps separate authority-scoped pending-attempt state and successful-binding state, not a set of bump attempts and not a cached preparation outcome. The live binding carries the exact attempt ID as a continuation lease for every split leaf in that tab generation. A healthy live binding, including a bounded empty-primary activation gap, suppresses correction; an unresolved tab is reconsidered on wake, snapshot completion, and preparation completion with at most one tab-wide attempt in flight. One authority chain preserves its complete attempt history and has a hard limit of two automatic attempts. A timeout taking longer than the former rolling 30-second window cannot age out the first attempt and start a third automatic attempt; later wake, snapshot, and preparation triggers remain exhausted until authority replacement rotates pending, binding, and history state. + +## Design + +### 1. Composed provider authority and host-qualified IPC + +Add `SshProviderEpoch` to the shared SSH types and compose it with the existing main-owned connection generation in `src/main/ssh/ssh-provider-authority.ts`. This module owns atomic rotation and delegates generation storage/assertion to `ssh-connection-generation.ts`; it does not introduce an independently advancing clock. + +The direct SSH state boundary becomes: + +```ts +type SshProviderEpoch = string & { readonly __sshProviderEpoch: unique symbol } +type ProviderRequestId = string & { readonly __providerRequestId: unique symbol } +type WaiterLeaseId = string & { readonly __waiterLeaseId: unique symbol } +type SshExecutionHostId = Extract + +type DirectSshStateAuthority = { + providerEpoch: SshProviderEpoch | null + connectionGeneration?: number +} + +type DirectSshAuthority = { + targetId: string + providerEpoch: SshProviderEpoch + connectionGeneration: number +} +``` + +The epoch wire value is a bounded opaque string. Branding is compile-time only. Main state broadcasts and `ssh:getState` include the pair; renderer state stores it without interpretation. `rotateSshProviderAuthority` is the only transition writer and `assertSshMutationExpectation` observes the generation advanced by that same call. + +Extend preload/main detected-worktree APIs: + +```ts +type LocalDetectedWorktreeRequest = { + providerRequestId: ProviderRequestId + repoId: string + executionHostId: typeof LOCAL_EXECUTION_HOST_ID +} + +type DirectSshDetectedWorktreeRequest = { + providerRequestId: ProviderRequestId + repoId: string + executionHostId: SshExecutionHostId + expectedAuthority: DirectSshAuthority +} + +type ListDetectedWorktreesArgs = LocalDetectedWorktreeRequest | DirectSshDetectedWorktreeRequest + +type AuthoritativeHost = + | { + kind: 'local' + executionHostId: typeof LOCAL_EXECUTION_HOST_ID + } + | ({ + kind: 'direct-ssh' + executionHostId: SshExecutionHostId + } & DirectSshAuthority) + +type HostQualifiedDetectedWorktreeResult = + | { + status: 'complete' | 'non-authoritative' + providerRequestId: ProviderRequestId + repoId: string + authority: AuthoritativeHost + result: DetectedWorktreeListResult + } + | { + providerRequestId: ProviderRequestId + executionHostId: ExecutionHostId + status: + | 'canceled' + | 'timed-out' + | 'stale' + | 'ambiguous-owner' + | 'authority-unknown' + | 'rejected' + } +``` + +`DirectSshDetectedWorktreeRequest` requires the full pair as one `expectedAuthority`; local requests cannot carry it. Construction and runtime admission also require `executionHostId === toSshExecutionHostId(expectedAuthority.targetId)`. Every data-bearing direct-SSH response, including `non-authoritative` metadata fallback, is therefore impossible to construct without both fields. Runtime validation rejects decoded SSH data payloads missing either component even if an untyped or older boundary fabricates one. Main owns the 30-second provider deadline; no renderer-supplied timeout can extend it. The desktop handler rejects runtime hosts. Keep an explicitly unqualified legacy overload only for existing callers during migration; it fails closed when more than one host owns the repo ID and is removed after all callers pass a host. + +Main selects the repo and provider before starting work, captures the provider object and full authority, and checks all three again after `provider.listWorktrees`. A host-qualified SSH response cannot be restamped by renderer as another host. + +Use host-qualified lineage ownership as well: + +```ts +type ListDesktopLineageForHostArgs = + | { executionHostId: typeof LOCAL_EXECUTION_HOST_ID } + | { + executionHostId: SshExecutionHostId + expectedAuthority: DirectSshAuthority + } + +type HostLineageSnapshot = + | { + authoritative: true + authority: AuthoritativeHost + worktreeLineageById: Record + workspaceLineageByChildKey: Record + } + | { + authoritative: false + executionHostId: ExecutionHostId + reason: 'ambiguous-owner' | 'authority-unknown' | 'stale' | 'unavailable' + } +``` + +Main filters the snapshot to the requested host. Renderer replaces only an authoritative discriminated host scope; malformed SSH authority is rejected before merge. Direct SSH preparation replaces the current bare `fetchWorktreeLineage()` call with this host-qualified API; it does not substitute `{ forceLocalOwner: true }`. + +Main destructive pruning must use qualified repo/worktree ownership. An existing row `meta.hostId` must agree with the resolved repo host in every case. Only an absent legacy host may be inferred when exactly one stored repo owns the repo ID, preserving today's path-reuse cleanup. When multiple hosts can own the ID, pruning requires row `meta.hostId`; absence or conflict makes the result non-authoritative and preserves the row. Authoritative scans backfill absent `meta.hostId` so legacy rows self-heal. Never use repo-ID-prefix pruning across hosts. + +The shared renderer store and web preload retain their existing non-direct-SSH callers. Preserve the legacy/runtime overload and its argument/echo shape in `web-preload-api.ts`, but do not broaden the web client into direct-SSH coordination: paired web clients cannot subscribe to desktop `ssh:state-changed`, so the proposed total direct-SSH web break is not reachable. Shared API type changes still receive compatibility tests so a runtime-routed web read is not rejected merely because the wrapper dropped its requested host. + +### 2. Exact direct SSH target scope + +Add `src/renderer/src/lib/direct-ssh-target-scope.ts`: + +```ts +type DirectSshGitRepoRef = { + repoId: string + executionHostId: SshExecutionHostId +} + +type DirectSshTargetScope = { + catalogRevision: number + gitRepos: DirectSshGitRepoRef[] + gitWorktreeIds: Set + terminalWorkspaceKeys: Set + lineageWorkspaceKeys: Set + ambiguousOwnerCount: number + contradictoryOwnerCount: number +} +``` + +Resolution rules: + +- Build the expected host with `toSshExecutionHostId(targetId)`. +- Resolve repos by `(repo.id, executionHostId)`. +- Collect explicit worktree host, exact repo-derived host, projected runtime owner, and any restored host evidence before selecting a row. +- If two present sources disagree, classify the row as `contradictory-owner`; preserve it and exclude it from refresh, merge, terminal retry, snapshot projection, and pruning. +- When explicit worktree host is present and no source contradicts it, require it to equal the expected host. Use exact repo-derived ownership only when the explicit worktree host is absent. +- Require `getExplicitRuntimeEnvironmentIdForWorktree` to be `null`; an explicit runtime owner contradicts direct SSH even when another source names the expected SSH host. +- Do not use focused-runtime fallback ownership during pre-catalog reconnect. Focus-only local/runtime results and `runtime:unresolved-owner` are ambiguous. +- Do not use `buildWorktreeByIdIndex`, raw `getKnownWorktreeById`, or another first-wins ID-only lookup as authoritative direct-SSH ownership. Hydration and reattach use an exact host-qualified row or fail closed. +- Accept a folder workspace only when its effective connection is exactly `targetId`, its execution host is expected, runtime owner is `null`, and all candidate repo/group/workspace provenance agrees. +- Treat mixed/conflicting folder provenance as contradictory; duplicate same-host owners and unresolved legacy rows are ambiguous/unowned. +- A parsed live app-SSH PTY can recover a stale-catalog terminal only when no explicit other-host or runtime ownership contradicts it. + +Git refresh uses `gitRepos`; terminal clear/retry uses raw Git IDs and folder keys from `terminalWorkspaceKeys`; unified lineage uses `worktree:` and folder keys from `lineageWorkspaceKeys`; snapshot projection uses `gitWorktreeIds`. Folder workspaces never enter the path-based remote-workspace schema. + +When exact repo rows are missing, use a new host-scoped desktop catalog read rather than focused `fetchRepos()` or an all-desktop refresh: + +```ts +listReposForExecutionHost({ + executionHostId, + expectedAuthority +}) +``` + +Main validates explicit and legacy ownership before producing the host snapshot. A row with contradictory `executionHostId` and `connectionId` cannot be filtered into one host by precedence or silently omitted from the other; a contradiction touching the requested host returns a non-authoritative catalog with no rows. + +The renderer merges the immutable response into only that host scope after a full-authority fence. This action owns a per-host catalog revision and in-flight entry; it does not share `reposFetchGeneration` with focused-runtime or all-host fetches. Thus a concurrent runtime-focused catalog refresh cannot silently supersede direct SSH hydration. +Its authoritative response uses the same `AuthoritativeHost` discriminant as detected worktrees and lineage, so direct-SSH catalog data also requires the complete pair. + +### 3. Bounded and cancelable direct SSH provider scheduler + +Add `src/renderer/src/hooks/direct-ssh-worktree-refresh-scheduler.ts`. It is owned by the `useIpcEvents` effect and used only for direct SSH coordinator scans. + +Required behavior: + +- at most `DIRECT_SSH_WORKTREE_SCAN_CONCURRENCY` (five) locally unsettled coordinator-owned detected-worktree requests in flight; +- owner-aware round-robin selection by target, with repos submitted incrementally rather than flattening one target into a global FIFO; +- no fixed collection window for an idle singleton request; +- an input key of `(repoId, executionHostId, providerEpoch, connectionGeneration, catalogRevision, authoritative requirement)`; +- join only a currently running logical repo task with the exact same key; +- retain the logical key across a first `retrying` timeout and delete it only on a terminal outcome; +- explicit `complete`, `non-authoritative`, `timed-out`, `cancel-budget-exhausted`, `canceled`, `stale`, and `rejected` outcomes; and +- no console error or degraded count for expected cancellation/supersession. + +Each provider invocation has the existing 30-second main-owned deadline. Main creates an `AbortController`, passes its signal to `SshGitProvider.listWorktrees`, and therefore reaches the multiplexer `rpc.cancel` path on timeout. A transient first timeout changes the repo task to `retrying` and requeues it once at the tail of that target's round-robin lane if the full authority remains current. That repo task promise does not settle, and target lineage/token creation does not start, until the retry completes, reaches its second timeout, is invalidated, or retry admission terminates as `cancel-budget-exhausted`. Add cancellation IPC keyed only by `providerRequestId`; authority advance, target invalidation, last-waiter release, and effect teardown abort matching main requests. Queued requests have no provider request ID and cancel without IPC. + +The first timed-out provider invocation and its leases settle before retry admission. The logical repo task remains pending and acquires a fresh provider request ID plus fresh waiter leases for the retry; preparation waiters never reuse an already-canceled provider identity. + +Cancellation uses waiter leases: + +- `waiterLeaseId` and `providerRequestId` are different opaque types generated independently. A provider request ID names one underlying preload/main/provider invocation; every consumer of that shared invocation receives its own renderer-only waiter lease ID. +- The shared detected-worktree coalescer, not the direct coordinator alone, owns the lease registry so sidebar/filesystem consumers also keep a joined provider invocation alive. +- Canceling or superseding one lease settles only that consumer. It does not call cancellation IPC while any other lease remains. +- Releasing the last lease sends exactly one cancellation IPC carrying the provider request ID and captured host/authority. Main never receives, stores, or accepts waiter lease IDs. +- Main aborts the provider request when that cancellation identity matches or when provider authority is invalidated. It does not reconstruct waiter ownership. +- Local cancellation returns after waiter settlement and, for the last lease, main provider-promise settlement. `ssh-channel-multiplexer` rejects its local provider promise when it sends fire-and-forget `rpc.cancel`; no relay response is awaited. +- The scheduler releases the local slot when the underlying provider promise settles locally. The original relay handler may observe abort later, so this metric is not a hard relay-process concurrency claim. +- Track every locally canceled underlying call as conservative cancel debt on its provider instance. Admission requires `locallyUnsettled + cancelDebt <= DIRECT_SSH_PROVIDER_START_BUDGET` (seven), so five canceled calls permit at most two replacements and repeated cancel/retry cannot create unbounded client-originated work. Debt is not cleared by elapsed time or local promise settlement because neither proves relay completion; it clears only when the owning provider/multiplexer is disposed or replaced. A logical task denied admission by this budget settles terminally as `cancel-budget-exhausted`; it never waits for provider replacement and never leaves the preparation barrier pending indefinitely. A hard bound on handlers surviving disposal is impossible without a relay acknowledgement, so telemetry states this as a seven-start per-provider budget rather than a total remote-process guarantee. + +```ts +type DetectedWorktreeRefreshLease = { + waiterLeaseId: WaiterLeaseId + providerRequestId: ProviderRequestId + result: Promise + release(reason: 'superseded' | 'invalidated' | 'stopped'): void +} +``` + +Each lease has its own settlement promise. Normal provider settlement resolves all remaining leases and removes the provider entry automatically; early `release` is idempotent and settles only that lease as canceled. + +Every other preparation await is bounded too: host-scoped catalog and lineage IPC use five-second deadlines, workspace hydration retains its ten-second deadline, and existing remote-workspace RPC deadlines remain in force. Catalog and lineage waiters accept coordinator cancellation; because their main work does not launch a provider process, a late reply is discarded by the renderer fence rather than holding a scheduler slot. + +The existing runtime project scheduler keeps its own five-worker pool, 250 ms debounce, and 5-second minimum interval. Sidebar and filesystem-event refreshes remain unchanged. Cross-subsystem isolation is intentional; the coordinator's bound is not presented as a renderer-wide bound. + +Keep the public `detectedWorktreeRefreshKey` shape unchanged. Its in-flight entry records a provider invocation identity and a lease map; direct-SSH authoritative work may join only when host and full authority also match. An incompatible entry under the same public key gets a separate underlying invocation rather than an unsafe join. The coordinator's authority/revision key wraps this coalescer without fragmenting compatible sidebar or filesystem-event sharing. The shared coalescer owns provider request IDs and waiter leases; the coordinator owns authority/revision fencing, retry state, and scoped metrics. + +### 4. Per-target reconnect coordinator + +Add `src/renderer/src/hooks/direct-ssh-reconnect-coordinator.ts`, instantiated once in `useIpcEvents`: + +```ts +type DirectSshAuthority = { + targetId: string + providerEpoch: SshProviderEpoch + connectionGeneration: number +} + +type PreparationInput = DirectSshAuthority & { + catalogRevision: number + repoRefs: DirectSshGitRepoRef[] + authorityRequirement: 'required' | 'allow-metadata-fallback' + snapshotRevision?: number + reason: 'reconnect' | 'initial-hydration' | 'workspace-snapshot' | 'wake-refresh' +} + +type DirectSshReconnectCoordinator = { + requestReconnect(authority: DirectSshAuthority): Promise + prepareOnly(input: PreparationInput): Promise + finalizeHydratedTerminals(authority: DirectSshAuthority): number + correctUnboundTerminals(authority: DirectSshAuthority, reason: CorrectionReason): number + replaceAuthority(authority: DirectSshAuthority): void + invalidate(targetId: string): void + stop(): void +} +``` + +There is no global reconnect wave and no authority-long prepared-outcome cache. Transient per-tab pending/live-binding state is separate and exists only to settle or re-arm terminal recovery. + +`replaceAuthority` compares the complete authority tuple. An exact-equal replacement is a no-op: it does not settle leases, clear pending/live terminal state, cancel provider work, or fragment an overlapping preparation. Only a different tuple performs authority replacement. + +#### Reconnect-finalization flow + +```ts +async function requestReconnect(authority) { + if (!isCurrentConnectedAuthority(authority)) return stale() + + // Authority replacement first settles all obsolete local leases and fences their late work. + coordinator.replaceAuthority(authority) + + // A missed disconnect can leave a non-null PTY from the old provider incarnation. + invalidateStaleDirectSshTargetPtyBindings(authority) + + // Terminal-critical and synchronous: no catalog, Git, lineage, or other target can gate it. + const retried = retryDirectSshTargetPanes(authority) + + // Relay flapping never delays terminal recovery, but it does damp full Git preparation. + if (!hasAuthorityBeenStableFor(authority, RELAY_LOST_STABILIZED_MS)) { + scheduleLatestAuthorityPreparation(authority, RELAY_LOST_STABILIZED_MS) + return terminalOnlyOutcome(retried, 'stabilizing') + } + + const input = await capturePreparationInput(authority, 'reconnect') + if (!input.ok) return terminalOnlyOutcome(retried, input.reason) + + const prepared = await prepare(input.value) + if (!prepared.token || !isCurrentConnectedAuthority(authority)) { + return combine(retried, prepared) + } + + // Catch tabs whose exact ownership or hydration became visible during this target's preparation. + const discoveredRetries = correctUnboundTerminals(authority, 'preparation-complete') + void syncRemoteWorkspaceAfterConnect(prepared.token) + return combine(retried + discoveredRetries, prepared) +} +``` + +The first terminal retry is complete before `capturePreparationInput` performs any await. Target B therefore retries even when target A has five slow provider requests. A same-authority duplicate runs bounded correction: healthy live bindings are no-ops, pending attempts are not duplicated, and failed/unbound tabs can re-arm. When workspace hydration completes, `finalizeHydratedTerminals` reruns against the current authority and handles newly hydrated or still-unbound tabs. + +Preparation for each target progresses independently. While authority remains current, it performs its host-scoped lineage read only after every repo task reaches a terminal state: `complete`, `non-authoritative`, final `timed-out`, `cancel-budget-exhausted`, or `rejected`. Authority-wide `canceled`/`stale` returns without lineage or a token. A first retryable timeout is the nonterminal `retrying` state and cannot release lineage, terminal correction, sync, or token creation. The target never waits for another target's repos or lineage. + +When authority rotates again within `RELAY_LOST_STABILIZED_MS` (currently five seconds), replace the delayed preparation with the latest authority and perform terminal finalization immediately. Only the authority that survives the stabilization window starts catalog/Git/lineage work. A same-authority wake during that window coalesces into the pending latest-authority preparation. This is damping, not an epoch-long result cache. + +#### Preparation-only flow + +`prepareOnly` runs catalog/worktree/lineage preparation and returns a token. It never invokes terminal retry and never starts reconnect sync. An unsolicited snapshot uses this mode, then applies that snapshot with the returned token. + +Reconnect and preparation-only requests may share exact overlapping catalog, repo, or lineage promises through ref-counted waiter leases. Superseding one consumer settles only its lease; it does not abort work still owned by another current consumer. They do not share finalization side effects. + +#### Input-scoped deduplication + +Preparation captures concrete inputs: exact authority pair, catalog revision, sorted repo/host refs, authoritative requirement, and snapshot revision when present. Only currently overlapping operations with identical relevant inputs join. + +Completed entries are removed immediately. Consequently: + +- a later same-authority wake rebroadcast runs another bounded refresh; +- a later snapshot revision runs another bounded preparation; +- a newly discovered repo changes the catalog revision/repo fingerprint and cannot join an older scope; +- a snapshot received during reconnect can share the still-running provider reads; and +- the reconnect call chain can pass its completed token directly to sync/apply without a second preparation. + +The token is an operation result, not a coordinator cache entry: + +```ts +type DirectSshPreparationToken = { + authority: DirectSshAuthority + catalogRevision: number + repoFingerprint: string + authorityRequirement: PreparationInput['authorityRequirement'] + snapshotRevision: number | null + outcome: 'complete' | 'degraded' +} + +type SnapshotApplyToken = DirectSshPreparationToken & { + snapshotRevision: number +} +``` + +An unsolicited snapshot passes its revision into `prepareOnly`, so the returned token is already snapshot-bound. Reconnect preparation returns `snapshotRevision: null`; after `remoteWorkspace.get`, sync revalidates authority and creates a `SnapshotApplyToken` by copying the fetched revision onto that token. `applyRemoteWorkspaceSnapshot` accepts only `SnapshotApplyToken` and requires exact revision equality, so it cannot reuse preparation across incompatible snapshots. + +### 5. Fenced worktree, catalog, and lineage merges + +Refactor detected-worktree listing so provider acquisition and store mutation are separate: + +```ts +const listed = await listDetectedWorktreesForRepoCoalesced(request) +if (!isCurrentHostAuthority(request, listed)) return canceled('stale') + +// No code using listed.result may occur above this fence. +return mergeDetectedWorktrees(listed.result, request) +``` + +`mergeDetectedWorktrees` performs the sole renderer mutation for that result. It owns git-identity routing, review-link sanitation, purge state, and both worktree maps in one fenced path. It must not start an unfenced lineage refresh. + +The existing shared coalesced refresh key already includes `executionHostId` and remains unchanged. Add the full authority and concrete input revision only to the coordinator wrapper key. Do not describe host parsing as new key behavior and do not alter cross-subsystem coalescing. + +Host-scoped catalog and lineage functions likewise return immutable results. Each has one merge entry point that revalidates the current exact authority inside the Zustand updater. A stale result produces zero publications. + +Main uses the same pattern around provider work: + +```ts +const authority = resolveExactProvider(args) +const gitWorktrees = await authority.provider.listWorktrees(repo.path, { signal }) +if (!stillOwnsExactProvider(authority, args.expectedAuthority)) return stale() + +return buildAndCommitAuthoritativeResult(authority, gitWorktrees) +``` + +No prune, root-memory update, or metadata backfill occurs before `stillOwnsExactProvider`. + +### 6. Atomic terminal disconnect and retry + +Add terminal-slice actions: + +```ts +clearDirectSshTargetPtyBindings(targetId: string): number +invalidateStaleDirectSshTargetPtyBindings(authority: DirectSshAuthority): number +retryDirectSshTargetPanes(authority: DirectSshAuthority): number +settleDirectSshPaneRetry(result: DirectSshPaneRetryResult): void +``` + +Put pure projections in `src/renderer/src/store/slices/direct-ssh-terminal-recovery.ts`. + +`clearDirectSshTargetPtyBindings` traverses `tabsByWorktree` once, selects exact target scope, then applies the `tab.ptyId != null` predicate. For every affected tab the same atomic projection sets `tab.ptyId` to `null`, empties its `ptyIdsByTabId` entry, consumes `pendingActivationSpawn`, and removes pending Codex restart/restart-notice entries for the cleared live PTY. It preserves `lastKnownRelayPtyIdByTabId`, layouts, deferred SSH sessions, pending reconnect IDs, shutdown/suppression state, IDs, titles, generations, and agent state. It lazily clones only changed workspace arrays and maps, commits one patch, and triggers no activity, sorting, or metadata persistence. Tabs without a current `ptyId`, including those with `pendingActivationSpawn`, are untouched. + +`invalidateStaleDirectSshTargetPtyBindings` validates the authority inside the updater and applies that complete atomic projection to a non-null `ptyId` when its transient `ptyAuthorityByTabId` does not equal the current authority. Snapshot-imported or legacy bindings without current-authority provenance are wake hints, not live bindings. + +`retryDirectSshTargetPanes` validates the exact authority inside the updater, resolves scope from that same state snapshot, applies `shouldRetryPaneSpawnOnSshReconnect` plus stale-binding evidence, excludes only current live-success and pending-attempt tab IDs, and commits one `tabsByWorktree` patch. It records a unique tab-wide attempt outside the success ledger. `settleDirectSshPaneRetry` records current-authority success only after a live PTY binding is committed. A failed or timed-out first attempt rotates the tab once; an exhausted second attempt retains continuation authority for sibling callbacks but cannot start a third attempt. + +`clearTabPtyId` keeps genuine single-PTY exit semantics, but split recovery adds two exact-authority projections: promote an already-bound surviving PTY under the same lease, or preserve the lease and activation suppression across an empty-primary gap until a same-attempt sibling commits or settles. `syncPaneDetachPtyOwnership` likewise projects one current split lease and history to both resulting tabs without spawning, exiting, or changing authority, even when the pending attempt has not produced its first PTY. A pane mounted after the first sibling succeeds captures the retained live lease; every spawn callback rechecks the full authority pair and retires a stale provider PTY. Permanent target removal continues through `src/renderer/src/store/slices/ssh-target-cleanup.ts`, whose deletion of last-known and deferred liveness is invalid for a reconnectable disconnect. + +`applySshConnectionStateChange` receives an explicit origin and becomes orchestration: + +```ts +type SshStateApplyOrigin = 'push' | 'initial-hydration' + +const applySshConnectionStateChange = (targetId, state, origin: SshStateApplyOrigin) => { + const previous = getSshConnectionState(targetId) + setSshConnectionState(targetId, state) + + if (isTerminalFailure(state.status)) { + coordinator.invalidate(targetId) + clearRemoteDetectedAgents(targetId) + clearPortForwards(targetId) + setDetectedPorts(targetId, []) + clearDirectSshTargetPtyBindings(targetId) + return + } + + if (state.status === 'connected') { + if (!state.providerEpoch || state.connectionGeneration === undefined) { + void reconcileAuthorityOnce({ + targetId, + initiatingEventWatermark: getStateEventWatermark(targetId), + initiatingState: state, + initiatingOrigin: origin + }).then(applyAuthorityPatchIfStillCurrent) + } else { + const authority = { + targetId, + providerEpoch: state.providerEpoch, + connectionGeneration: state.connectionGeneration + } + + if (origin === 'initial-hydration') { + coordinator.replaceAuthority(authority) + void coordinator.prepareOnly({ + ...authority, + authorityRequirement: 'required', + reason: 'initial-hydration' + }) + } else if ( + previous?.status !== 'connected' || + previous.providerEpoch !== state.providerEpoch || + previous.connectionGeneration !== state.connectionGeneration + ) { + void coordinator.requestReconnect(authority) + } else { + coordinator.correctUnboundTerminals(authority, 'wake-refresh') + void prepareAndSyncWithoutHealthyTerminalRemount({ + ...authority, + reason: 'wake-refresh' + }) + } + } + } +} +``` + +Increment the per-target state-event watermark before applying every push event. `setSshConnectionState` must publish when either authority component changes. Reconciliation may only patch missing authority onto the still-current initiating state; it never enqueues a complete stale state reply. + +The terminal-failure cleanup order remains `clearRemoteDetectedAgents`, `clearPortForwards`, `setDetectedPorts([])`, then atomic PTY binding clear. Preserve the current port-broadcast race defense and detected-agent re-detection behavior. + +An already-connected same-authority rebroadcast is a wake refresh, not a healthy-pane remount. It performs bounded unbound/stale correction, fresh bounded preparation, and sync. Initial hydration always carries `origin: 'initial-hydration'` and uses `prepareOnly`; it is never inferred from the absence of `previous`. A bounded authority reconciliation retains the initiating origin, so filling a retained state's missing pair also cannot become a reconnect transition. Hydrating an already-live state must not remount healthy panes. Workspace session completion invokes `finalizeHydratedTerminals` only for reconnect authorities recorded during that hydration interval, but a failed/unbound attempt remains eligible for later same-authority triggers. + +## Remote-workspace data flows + +### Reconnect sync + +1. Reconnect finalizes qualifying terminals immediately. +2. Its target-scoped preparation returns a token. +3. Before awaiting `remoteWorkspace.get`, `syncRemoteWorkspaceAfterConnect(token)` captures whether the exact target currently has local tabs. This capture-before-await ordering is load-bearing. +4. The function validates the token, obtains the snapshot, and passes the same token to `applyRemoteWorkspaceSnapshot`. +5. Snapshot apply does not prepare again and is preparation-only with respect to coordinator retry; existing snapshot-driven `reconnectPersistedTerminals` behavior remains. +6. For `revision === 0`, mark hydration and publish the current local session only when the pre-await `hasLocalTabs` capture was true. Revalidate authority before upload. Do not recompute that predicate after preparation/hydration, which could overwrite a newer relay snapshot with locally imported state. +7. Snapshot projection and persisted-terminal reconnect receive only host-qualified worktree references from the token's exact target scope. They cannot reset, replace, remove, or reattach sibling SSH, local, WSL, or runtime-owned tabs or their PTY indexes, layouts, active selection, generations, retry state, or live-binding state, even when raw repo/worktree IDs or paths collide. + +### Unsolicited snapshot + +1. Capture current target authority and the incoming snapshot revision. +2. Call `prepareOnly` with those concrete inputs. +3. Wait for existing workspace-session hydration, bounded by the current 10-second deadline. +4. Capture the target terminal-recovery revision and same-ID local tab recovery fields before snapshot projection. +5. Revalidate the token, snapshot revision, arrival order, and recovery revision immediately before merge. If recovery advanced, rebase the projection on the latest local recovery fields rather than applying the stale captured copy. +6. Apply once as preparation-only. For a same-ID tab, preserve any newer local `generation`, pending attempt, successful current-authority binding, and terminal-recovery revision. Remote `generation` is not comparable across clients and cannot overwrite a local retry. Imported `ptyId`/pending reconnect data is a wake hint until `reconnectPersistedTerminals` settles and current-authority binding provenance is recorded. +7. Run the target-scoped, host-qualified `reconnectPersistedTerminals`, then `finalizeHydratedTerminals` for a reconnect authority. A failed reattach clears pending state and re-arms correction; a successful exact reattach atomically retires its pending attempt and records the current binding without an extra bump. +8. If path resolution still reports unknown worktrees, record a degraded result; do not loop unboundedly. + +A later same-authority snapshot always receives a new preparation attempt after earlier work completed. This preserves convergence when another client creates a worktree while the connection stays live. + +Remote snapshot identity is repo-qualified where the schema provides repo identity: resolve by `(executionHostId, repoId, normalizedPath)` and fail closed on ambiguity. For legacy path-only entries, retain the existing resolver only when the path has exactly one candidate in the exact target scope. Two worktrees at the same absolute host path were not proven producible, so this is a robustness invariant rather than a claim that current storage necessarily creates that collision. + +The existing `buildWorktreeByIdIndex` and `reconnectPersistedTerminals` path retains first-wins ID-only compatibility for its current callers. Direct-SSH snapshot apply must pass host-qualified worktree refs through a dedicated overload or pre-resolved map; it cannot hand raw IDs back to an ID-only lookup and recover authority afterward. + +## Failure handling + +- **Unknown authority:** reconcile once behind the per-target arrival watermark; then fail closed with a retryable diagnostic. Do not use a renderer counter or apply the reply's status. +- **Catalog timeout/failure:** retain cached exact-owner scope, record degradation, and continue target preparation and already-completed terminal recovery. +- **One repo is non-authoritative:** keep its safe metadata fallback separate from operational failure and do not authoritatively delete rows. +- **One repo times out:** the provider invocation settles locally and sends best-effort cancel. On the first retryable timeout, keep the logical repo task and target preparation barrier pending in `retrying`, then requeue once at the target lane tail. A second timeout is final and degrades the repo. If current-provider cancel debt denies retry admission, settle the logical task as terminal `cancel-budget-exhausted`; this releases one degraded preparation outcome rather than an early-success token or an indefinite wait. None of these states blocks another target's terminal retry. +- **One repo rejects:** locally settle it without retry unless classified by the existing narrow transient predicate; operational rejection remains distinct from timeout and non-authoritative data. +- **Lineage timeout/failure:** preserve current lineage, mark target preparation degraded, and continue sync with exact cached worktree scope. +- **Authority advance or target invalidation:** synchronously cancel queued work, settle obsolete local waiter leases, send exactly one cancellation for every affected in-flight provider request ID, rotate renderer in-flight inputs and terminal-attempt state, and reject late results at both main and renderer fences. The new authority begins terminal finalization without waiting for relay acknowledgement. +- **Relay flapping:** finalize terminals for every new authority, but replace/defer full preparation until the latest authority survives `RELAY_LOST_STABILIZED_MS`. +- **Missed disconnect/stale binding:** clear only PTY bindings whose transient binding authority is absent or old, retain last-known relay identifiers, then retry under the new authority. +- **Failed terminal spawn/reattach:** settle the attempt as failed, remove it from pending/success state, and allow rate-limited correction on later preparation, hydration, snapshot, or wake triggers. +- **Workspace hydration timeout:** set existing per-target sync error; do not undo terminal or worktree recovery. Snapshot merge never replaces a newer local recovery revision. +- **Coordinator stop:** cancel queued work, locally settle every waiter, send best-effort aborts for unshared provider calls, and return without waiting for relay acknowledgement. Effect cleanup stops coordinator after subscriptions and before disposing its dedicated scheduler. +- **Unknown owner:** preserve state, count it, and retry on later host-qualified catalog input. +- **Contradictory owner:** preserve state, report the conflicting provenance classes without identifiers, and do not retry or mutate that row until a later catalog revision changes the evidence. + +No failure path falls back to unbounded `Promise.all`. + +## Observability + +Emit one aggregate diagnostic per target operation, not per global wave and not per repo/tab. Use `[direct-ssh-reconnect]` for reconnect finalization and `[direct-ssh-prepare]` for preparation-only work. + +Fields: + +- mode and reason; +- terminal panes retried, stale bindings cleared, successful corrections, and terminal-finalization duration; +- catalog outcome and duration; +- repo tasks completed, non-authoritative, retrying, final timed-out, cancel-budget-exhausted, canceled, stale, and rejected; +- direct-scheduler queue-wait and provider-execution duration distributions; +- timeout retry count, local waiter settlements, cancel debt, and replacement admissions delayed by cancel debt; +- peak locally unsettled coordinator-owned detected-worktree concurrency and estimated late-work allowance; +- lineage outcome; +- Git-worktree, folder-workspace, ambiguous-owner, and contradictory-owner counts; +- overlapping request joins; +- authority rotations observed and preparations damped during flapping; +- total target-operation duration. + +Expected supersession/cancellation is debug-level and does not increment degraded/error metrics. Timeout is separate from queue wait and operational rejection. `fetchWorktrees === false` is not used as a failure proxy; the new discriminated result preserves non-authoritative versus rejected outcomes. + +Do not log target IDs, repo IDs, paths, labels, hosts, usernames, credential errors, snapshot content, raw request IDs, or terminal output. A stable per-session opaque target alias may correlate concurrent aggregate events and is discarded at process exit. + +The product event deliberately omits terminal correction failure/re-arm counts, concurrent non-coordinator call counts, and arrival-order discard counts because this implementation has no truthful production observation for them. It does not populate unobserved fields with constant zeroes. + +Typed product telemetry is implemented with one strict identifier-free aggregate event per target operation. Queue and provider percentiles are derived from that operation's real scheduler samples. The seven-day dogfood dashboard/query is operational follow-up outside this repository; this PR does not claim a dashboard artifact. Schema tests reject identifiers and keep queue wait, execution, timeout, operational rejection, cancellation, and stale results distinct. + +The concurrency metric is explicitly `coordinator_owned_direct_ssh_detected_worktree_concurrency`. It measures locally unsettled provider promises and says nothing about runtime lineage RPCs, sidebar's eight-worker pool, filesystem-event calls, catalog/lineage IPC, total application provider concurrency, non-coordinator same-connection calls, or relay handlers finishing after local cancel. + +## Tests + +This implementation registers the worktree scan-count, host/authority, timeout-barrier, and no-cross-host mutation oracles in the existing `git-worktree.refresh-event-semantics` gate. It extends `terminal-provider.ssh-remote-reattach-contract` for direct-SSH binding clear/retry, hydration, folder workspace, paired-close non-interference, and #8255 wake isolation. A new reliability gate is unnecessary because those existing gates own the lifecycle contracts. + +### Main/preload host and authority contract + +- Preload forwards `repoId`, `executionHostId`, the complete expected authority, and `providerRequestId` unchanged; main owns the deadline and never receives `waiterLeaseId`. +- Renderer host intent across local, direct SSH A/B, and runtime-alias catalog rows routes to the exact provider. Fabricated duplicate main-store rows still fail closed as defense in depth. +- Desktop main rejects a runtime execution host. +- Zero or multiple same-host matches fail closed; unqualified legacy calls fail closed when ownership is ambiguous. +- Compile-time fixtures cannot construct a direct-SSH `complete` result or `authoritative: true` lineage snapshot without both authority fields. Runtime admission rejects malformed wire values that omit either field. Local authoritative variants carry neither SSH field. +- A response echoes exact host and complete authority; renderer rejects any host, target, epoch, generation, provider request, or discriminant mismatch. +- Relay loss/replacement, transport loss/replacement, provider disposal, target readoption, and permanent removal rotate epoch and generation in one helper. +- A per-target generation counter exhaustion rolls the process generation scope, revokes every target's old authority and mutation token, and aborts every old-scope provider request before new-scope admission. +- Relay-only replacement rejects both old reconnect/provider work and an old `SshMutationExpectation`. +- A fresh `connected` authority is not broadcast until its provider is registered. +- An old provider result after any rotation performs no root-memory, lineage-prune, or metadata-backfill mutation. +- Cancellation and timeout reach the provider `AbortSignal` and multiplexer `rpc.cancel`. +- Duplicate repo IDs never trigger cross-host repo-prefix lineage pruning. +- Legacy lineage prunes under a unique repo owner, ambiguous legacy rows are preserved, and an authoritative scan backfills `meta.hostId`. +- `sshConnectionStatesEqual`, retained-payload admission, public projection, preload push/get, startup reconnect, runtime retained/client payloads, renderer/runtime stores, and state builders preserve both authority fields. +- Main-originated broadcasts always publish the complete authority pair. Malformed epoch-only or generation-only retained inputs are rejected; compatibility push/get inputs can only remain `authority-unknown` for bounded reconciliation and perform no authoritative mutation. One valid pair change publishes once and an exact duplicate is a no-op. +- Retained-state admission accepts a bounded valid epoch, rejects malformed/oversized epochs, and never strips a valid authority component. +- The web preload compatibility overload preserves requested-host echo for runtime reads; this does not enable direct-SSH coordination in paired web clients. +- A stale `ssh:getState` reply arriving after a disconnect/reconnect push cannot change status or fill authority; a same-watermark reply can fill only missing authority. +- Main host-catalog admission rejects a row whose explicit execution host contradicts its legacy connection host; it returns no authoritative rows instead of selecting or hiding that row by precedence. + +### Renderer worktree/catalog/lineage fences + +- The coordinator in-flight key differs by host, full authority, catalog revision, and authoritative requirement; the shared coalescer key remains unchanged. +- Inputs that differ only by `authorityRequirement` do not join, and the resulting token echoes that exact requirement. +- Exact overlapping requests join; the same key after completion runs again. +- An old result after disconnect/reconnect or relay-only replacement causes zero store publications. +- Git identity, hosted-review links, purge state, both worktree maps, and best-effort lineage remain byte-identical on stale results. +- Local, another SSH target, and runtime owners with the same repo ID remain unchanged. +- Target snapshot hydration and persisted-terminal reconnect use host-qualified worktree references, prune the retry/live/history ledgers of tabs authoritatively deleted from that exact scope, and leave retained or sibling SSH, local, WSL, folder, and runtime tabs, PTY indexes, layouts, active state, generations, and recovery ledgers unchanged. +- A renderer worktree result is admitted only while every current same-ID repo row still has valid, non-contradictory explicit/legacy ownership; malformed or contradictory provenance introduced during the provider await makes the result stale without store mutation. +- A target-scoped catalog fetch cannot be superseded by focused-runtime `fetchRepos`. +- Host-scoped lineage deletes a stale direct SSH row while preserving local, another SSH target, runtime, and unknown-owner rows. +- Runtime-focused UI state cannot redirect direct SSH catalog, worktree, or lineage ownership. +- An ID-only first-wins hydration index containing the same worktree ID under SSH A and SSH B is never authoritative for direct reconnect; a target-B snapshot reattaches only the host-qualified B row or fails closed. +- Pre-catalog direct SSH scope with a focused runtime treats focus fallback as ambiguous and still recovers tabs supported by explicit PTY/host provenance. +- An explicit `ssh:B` worktree with repo-derived `ssh:A` is `contradictory-owner` for both targets and remains byte-identical. The inverse mismatch, an SSH host plus explicit runtime owner, and conflicting folder group/repo connections fail the same way. +- Repo-derived ownership is accepted only when explicit worktree ownership is absent; adding a conflicting explicit owner converts the same row from accepted to preserved/contradictory without cross-host deletion. +- Git 2.25-compatible worktree fallbacks remain unchanged. + +### Direct SSH scheduler/coordinator + +- A singleton reconnect begins terminal finalization immediately without a collection delay. +- Target B terminal finalization completes while all five direct provider slots are occupied by target A. +- Target B's first repo starts after at most one bounded provider deadline when it arrives behind five A calls. +- Round-robin admission prevents a large target from continually reoccupying every released slot. +- Peak coordinator-owned detected-worktree calls is five; runtime/sidebar activity can raise total app concurrency without failing this assertion. +- Joined consumers receive distinct waiter lease IDs and one shared provider request ID. Canceling one settles only that lease while the other completes from the original call; no provider cancel is sent. +- Last-waiter release sends exactly one cancellation for that shared provider request ID. Authority invalidation sends exactly one cancellation for each affected in-flight provider request, including multi-repo preparation; no cancellation is sent merely because one lease leaves while another current-authority lease still owns that invocation. A waiter lease ID presented to main is rejected and cannot abort provider work. +- A coordinator lease joining sidebar/filesystem work cannot abort that work when the coordinator is superseded; the remaining non-coordinator lease keeps the provider request alive. +- A timeout sends `rpc.cancel`, settles locally, and releases its local slot without a relay acknowledgement. +- Repeated timeout replacements never exceed the two-call cancel-debt allowance; denied work settles as terminal `cancel-budget-exhausted` and is reported separately. +- After a first retryable timeout, the repo task is `retrying`: lineage calls, preparation tokens, sync, and snapshot apply remain at zero until the retry settles. +- A successful retry then releases one lineage read and one token; a second timeout or cancel-budget exhaustion releases a degraded result without starving another target. +- An exact-equal `replaceAuthority` call preserves every pending lease, live binding, and overlapping preparation and sends no cancellation. +- A same-authority reconnect rechecks terminals but does not rebump a healthy current-authority binding. +- A newly hydrated tab receives one retry later under the same authority. +- A tab whose exact ownership becomes visible during that target's preparation receives one retry without delaying the first terminal finalization. +- An authority advance with five old slow calls cancels queued work, settles/aborts old leases, starts new terminal finalization immediately, admits new work under cancel-debt rules, and permits zero old main/renderer mutations. +- A changed authority supersedes old target work by arrival, without numeric comparison. +- A same-authority connected rebroadcast performs bounded correction plus preparation/sync without retrying healthy terminals. +- A failed or timed-out pane on attempt one rotates the tab once; attempt-two failure cannot start attempt three or revoke continuation authority from siblings already settling. +- Three authority rotations inside the stabilization window perform three immediate terminal checks but only one full preparation for the final stable authority. +- `prepareOnly` never invokes terminal retry or reconnect sync. +- A preparation-only request shares exact in-flight repo work with reconnect preparation but not reconnect finalization. +- A completed preparation never suppresses a later same-authority wake or snapshot preparation. +- Stop locally settles queued/in-flight waiters without waiting for relay acknowledgement and prevents post-stop finalization. +- One system resume/browser-online event advances #8255 remote-runtime backoffs and direct-SSH wake preparation independently; runtime-owned SSH rows never enter the direct coordinator, and a direct tab already live under current authority is not double-bumped. + +### Atomic terminal recovery + +- Many live tabs/worktrees clear in one store publication; a second clear is a true no-op. +- Only tabs with `tab.ptyId != null` are changed. +- A null-PTY tab with `pendingActivationSpawn` remains byte-identical. +- A live-PTY tab consumes `pendingActivationSpawn` in the same patch that clears its tab and split-pane PTY indexes. +- `lastKnownRelayPtyIdByTabId` survives and the `#9911` orphan predicate remains reconnectable. +- Live split-pane PTY indexes and Codex restart metadata clear. +- Layouts, deferred sessions, pending reconnect IDs, shutdown/suppression state, titles, and agent state remain unchanged. +- No worktree activity, sorting, or metadata persistence occurs. +- Exact target A clear/retry leaves target B, local, WSL, floating, and runtime-owned tabs unchanged even with duplicate repo IDs. +- Exact direct SSH folder workspaces clear/retry; mixed, ambiguous, and runtime folders do not. +- A parsed target PTY recovers a stale-catalog tab only without contradictory ownership. +- A relay/provider replacement after a missed disconnect clears a pre-authority `ptyId` and retries it while preserving last-known relay IDs. +- Binding provenance for another authority or no provenance is stale; a successful current-authority spawn becomes live and suppresses healthy correction. +- One authority chain permits at most two automatic correction attempts even when each timeout exceeds 30 seconds; later same-authority triggers remain exhausted until authority replacement. +- Rejected stale/mismatched acknowledgements preserve every store map and publish nothing. Concurrent split spawn or reattach acknowledgements share one exact attempt; the first establishes the fallback/live lease, and both already-mounted and post-success-mounted siblings join it. +- Primary exit before a sibling binds preserves the exact continuation lease and activation suppression; the sibling then becomes the fallback without a corrective remount. +- Primary and non-primary split detach both preserve exact authority and retry history on the surviving source and detached destination; an all-null pending-only detach preserves the lease before either side binds, and a same-authority correction leaves both live. +- Disconnect retains exact existing ordering and effects for `clearRemoteDetectedAgents`, `clearPortForwards`, `setDetectedPorts([])`, and atomic PTY clear. +- Disconnect and reconnect emit zero paired `session.tabs.close`/`closeLifecycle`, provider shutdowns, or process signals. +- A manually parked direct-SSH worktree follows the same store patch and retry eligibility without invoking parking, close, or layout mutation. + +### Remote-workspace and hydration integration + +- Connect plus sync performs one logical preparation and passes its token through a nonempty snapshot apply without preparing again. +- An unsolicited snapshot joins exact in-flight preparation but starts a new preparation after that work settles. +- A later same-authority snapshot referencing a newly created worktree resolves and imports its tabs. +- Preparation-only snapshot handling never bumps terminal generations. +- Preparation-only means no coordinator generation bump; existing snapshot-driven terminal reattach remains and is finalized afterward. +- Initial hydration with no previous renderer state follows the explicit `initial-hydration` origin into `prepareOnly` and performs zero reconnect retries; reconciliation retains that origin. +- Reconnect finalized before session hydration retries newly hydrated tabs exactly once afterward. +- Immediate finalization bumps a tab, then a snapshot with the same stable tab ID and an older/absent generation cannot reduce the local generation or suppress correction. +- Snapshot hydration that lands after a newer local retry preserves the newer terminal-recovery revision, pending attempt, and current binding provenance. +- Snapshot-imported `ptyId` without current-authority live evidence remains retry-eligible; successful exact target-scoped `reconnectPersistedTerminals` retires the pending attempt and records it live, while failure re-arms it. +- Snapshot projection and reconnect are host-qualified end to end; another SSH target, local, WSL, and runtime-owned state remain byte-identical despite colliding raw IDs or paths. +- Same-authority wake rebroadcast performs bounded fresh discovery. +- Revision-zero sync captures `hasLocalTabs` before `remoteWorkspace.get`, uploads only on that capture, and revalidates authority before publish. +- Snapshot apply rejects a token whose `snapshotRevision` differs, and reconnect sync can create a `SnapshotApplyToken` only from the snapshot fetched by that same fenced operation. +- Repo-qualified snapshot mapping keeps same-named repo paths isolated; a legacy path-only entry applies only with one exact-target candidate and otherwise fails closed. +- Folder workspace keys never enter snapshot projection. +- Hydration timeout does not undo terminal recovery. + +### Performance and diagnostics + +Seed direct SSH targets, a runtime environment, sidebar refreshes, worktrees, folder workspaces, split tabs, and large terminal maps.

Land complete-pair publication, malformed partial-authority rejection, retained-admission, stale-reconciliation, provider-before-broadcast, and old-mutation-expectation tests before any coordinator routing. +2. Add host-qualified detected-worktree and lineage IPC, discriminated authoritative response admission, exact main provider selection, main-owned 30-second deadline, provider-request cancellation, and main pre-mutation fences. Preserve the web/runtime overload without enabling direct-SSH web coordination. Keep the coordinator disabled. +3. Refactor renderer worktree/catalog/lineage reads to immutable results with pre-mutation full-authority fences. Add the host-scoped catalog lane independent of focused-runtime supersession, all-provenance contradiction rejection, legacy lineage host backfill, and shared coalescer leases with distinct waiter/provider IDs. +4. Add exact target scope, atomic disconnect clear, stale-authority binding invalidation, retry-attempt settlement, and transient binding provenance. Switch disconnect and reconnect terminal handling together so Git/folder clear-retry symmetry and detected-agent/port cleanup remain intact in every commit. +5. Add the dedicated fair direct SSH scheduler and per-target coordinator with local-settlement semantics, the first-timeout preparation barrier, one timeout retry, cancel-debt admission, authority-advance invalidation, same-authority correction, and flapping damping. Route connected events through reconnect finalization; leave #8255 remote-runtime recovery and runtime-owned SSH rows unchanged. +6. Extract `prepareRemoteWorkspaceTarget`, `syncRemoteWorkspaceAfterConnect`, and `applyRemoteWorkspaceSnapshot` into `src/renderer/src/hooks/remote-workspace-target-sync.ts`. Split preparation-only from reconnect mode, pass the full operation token through revision-zero push and snapshot apply, preserve newer local recovery state, finalize imported terminal hints, and remove repeated preparation calls. +7. Enable typed aggregate diagnostics/telemetry and dogfood with renderer-catalog owner aliasing, many direct targets, an active focused runtime, sidebar activity, folder workspaces, relay-only flapping, timeout/retry/cancel debt, missed disconnects, failed pane spawns, arrival-order races, system resume/browser online events, and cross-device snapshot changes. + +Stage 5 is gated on stages 2–4.

Every authoritative side effect is downstream of an exact host/authority fence. + +### Use `{ forceLocalOwner: true }` for direct SSH lineage + +Rejected. It cannot authoritatively replace an SSH host scope and leaves deleted SSH lineage behind. The wire response and renderer replacement scope must both name the exact execution host. + +### Reuse the component sidebar single-flight coalescer + +Rejected. It is component-scoped, fire-and-forget, and lacks provider-authority, cancellation, terminal, and preparation semantics. The coordinator instead acquires leases from the shared detected-worktree provider coalescer while preserving its public key shape. + +### Replace direct `Promise.all` with `refreshRuntimeProjectWorktrees` + +Rejected. It bounds only one invocation, remains host-blind at the desktop IPC boundary, and does not remove repeated preparation. + +### Use one scheduler per SSH target + +Rejected. It permits `5 × targetCount` locally unsettled provider calls. One dedicated fair scheduler provides a truthful five-local-call bound without a cross-target completion barrier; cancel debt states the separate late-relay allowance. + +### Wait for a relay cancellation acknowledgement + +Rejected. `rpc.cancel` is a notification and canceled handlers intentionally send no response. Local waiter/provider settlement releases scheduler ownership; late effects remain authority-fenced and replacement admission is bounded by cancel debt. + +### Expand direct SSH coordination to the paired web client + +Rejected. Paired web clients cannot subscribe to the desktop direct-SSH state path. Preserve shared overload compatibility and host echoes, but do not create a new direct-SSH web transport to address an unreachable version of the shim claim. + +### Apply a fixed collection debounce + +Rejected. It taxes the singleton common case and is unnecessary when exact overlapping work already coalesces. Fair incremental admission handles multi-target bursts. + +### Call `fetchAllWorktrees` + +Rejected. It refreshes unrelated hosts, weakens failure isolation, and collides with the separate sidebar surface. + +### Reuse permanent target-removal cleanup + +Rejected.

Reset and fresh-database paths cannot synthesize +legacy authority. + +## Durable principals and live authority + +After the hook server and PTY inventory are ready, a one-shot adoption service +may commit compatibility principals. It does not mutate terminal processes or +input. + +Before renderer hydration, legacy Dispatch evidence also fences automatic +provider resume for the exact sleeping pane. Once the relevant local daemon or +SSH relay has authoritative inventory, Orca intersects the durable handle, +pane, PTY ID, PTY incarnation, workspace, and host owner. A unique live match +is adopted into its original tab/leaf as inactive background state while the +coordinator tab remains active. Missing, stale, reused, cross-host, or +ambiguous evidence stays fenced and inspectable. Ordinary provider resume is +unblocked only when authoritative inventory proves that exact PTY exited. + +At hook-server startup, copy the validated hydrated status rows into an +immutable main-process-only startup snapshot before the server listens or +binds the new listener. Later live events update a separate current-runtime +observation map and cannot overwrite the pre-update commitment source. A +current event is preferred but is not required before the worker's first +post-restart lifecycle command when controller inventory proves the exact +original PTY and process incarnation are live. + +For each candidate it resolves the union of: + +- durable Dispatch assignee and pane; +- equivalent-pane aliases; +- remote attachment and host ownership; +- coordinator candidates from active legacy coordinator rows, Task creator + handles, Dispatch coordinator/parent provenance, and direct-message + sender/recipient history; +- the restored terminal inventory and process incarnation; and +- the hydrated, previously authenticated hook pane/launch-token association. + +The candidate commits only when that union identifies exactly one role and +row. The orchestration database stores a SHA-256 token commitment, never the +raw token. The existing owner-only hook status cache is an input to the +one-time commitment, but a hydrated status is not enough to mutate. + +Every compatibility call then requires: + +- a hidden launch token and pane inherited by the calling process; +- the immutable pre-update hook commitment, plus either a matching + current-runtime hook event or exact current controller proof of the original + PTY and process incarnation; +- a live PTY with the committed handle, host scope, and process incarnation; +- the committed principal and exact active legacy Dispatch or adopted Run; and +- an operation-specific unique match. + +The current hook event or exact controller inventory proves that the process +survived the restart; equality with the pre-update commitment proves it is the +same launch. If the hook cache was absent, the provider cannot report the +proof, the token changed, or any candidate is ambiguous, the row remains +read-only. + +For new Dispatches, persist the launch-token hash at dispatch time so later +contract updates do not depend on hook-cache recovery. Never return or log raw +tokens. Add explicit RPC-envelope, structured-log, error, and CLI JSON +redaction tests. + +Host scope is runtime-owned: + +- local: stable local execution-host identity; +- WSL: stable native execution-host identity plus distro; +- SSH: saved-host authority plus remote pane/process identity; and +- federated runtime: authenticated peer fingerprint plus remote attachment. + +`pickRemoteCliEnv`, SSH relay forwarding, WSLENV, and the legacy in-process SSH +fallback must carry the hidden evidence without exposing it in command text or +logs. A local runtime never accepts a raw remote token as local authority. +Pre-update WSL processes without the token cannot use the lifecycle adapter. + +For SSH, the host passthrough and in-process fallback stamp the saved target, +`SshRelaySession` connection incarnation, and attachment provenance from the +authenticated runtime channel; caller environment cannot choose them. WSL +stamps the runtime-owned native host and distro in both the full bridge and +fallback bridge. The verifier intersects those stamps with the committed host +scope before considering token or pane evidence. + +## Mixed-contract Run and mail routing + +The adopted Run is a normal current Run. Tasks belong to it, so a current retry +of a preserved Task naturally routes to the same Run without a cross-Run Task +reference. + +Message delivery is selected by `messages.delivery_contract`, not by Run ID: + +- old and adapter-created direct messages are `legacy_direct`; +- current sends are `current_delivery`; and +- migration rejections and non-actionable history are `audit_only`. + +Current Run Delivery creation, filtering, waiting, and acknowledgment select +only `current_delivery`. Legacy `check` selects only the exact principal's +`legacy_direct` address. History and inbox may show all three with explicit +labels but never attach actions to `audit_only`. Mixed legacy/current attempts +under one Task are covered across send, ask, check, reply, and settlement. + +The original coordinator is automatically associated with the adopted Run +after its principal proves live. `run-use` may bind that same principal without +converting legacy Dispatches. A different coordinator cannot silently take +over while a legacy attempt is active; an explicit recovery takeover is a +separate current-contract action and revokes legacy coordinator mutation +authority before rebinding. + +When that coordinator uses old direct `check`, the adapter also performs a +non-consuming existence check for `current_delivery` mail. It never mixes the +messages into legacy output; it prints the exact current Run check command and, +after that command creates a Delivery, the exact acknowledgment form. This +keeps an unchanged coordinator informed about current retries without +weakening current Delivery semantics. + +## Exact legacy adapter + +The CLI keeps accepting the old flags. It sends a hidden compatibility +envelope; the runtime, not the CLI, decides whether legacy behavior applies. + +Version B generates a random hidden `compatibilityInvocationId` once per CLI +process and reuses it for every transport reconnect by that invocation. +`legacy_operation_receipts.operation_key` is this invocation ID for B calls. +The method and canonical payload hash must also match. + +Attested compatibility calls bypass the rotating-auth generic mutation ledger +after the contract fence routes them to the adapter. Their only dedupe boundary +is the compatibility-principal receipt transaction described here; current +calls continue through the existing generic ledger unchanged. + +Version A had no invocation ID. Cross-cutover reconstruction is therefore +limited to effects with a durable semantic identity: final settlement per +Dispatch, still-pending ask per normalized question/options/recipient, reply +per source/principal/body, and read recovery per message. Heartbeat and +escalation remain at-least-once across an A-to-B manual retry because +collapsing identical commands could suppress a legitimate later event. Tests +and guidance do not promise cross-cutover exactly-once behavior for those +repeatable signals. + +An A-era ask that was already answered before its output was lost is also +ambiguous. B does not guess whether the same text means retry or a new +question. Its answer is in the durable recovery cohort and the error tells the +agent to run the exact legacy check command first. After that answer is printed +and acknowledged, a new B invocation with identical text creates a new +question. If multiple identical A threads exist, ask fails ambiguous and +recovery check drains them by message sequence; no arbitrary thread is chosen. + +### Lifecycle `send` + +- `heartbeat` and `worker_done`: resolve Task + Dispatch from the payload, then + intersect them with the verified worker principal. +- `escalation`: resolve Task + verified worker principal to exactly one active + legacy Dispatch because the old prompt supplied no Dispatch ID. +- Preserve the old direct coordinator recipient after verifying it belongs to + the adopted Run principal. +- Infer missing `worker_done` outcome as `failed` only when the trimmed subject + is `Failed` or begins `Failed:`; otherwise infer `succeeded`. +- Normalize to the current internal settlement model. + +Compatibility validation happens before message insertion. Current lifecycle +handling is not refactored through this prevalidation: its existing +invalid-capability audit message behavior remains locked by regression tests. + +The DB commits the direct message, lifecycle effect, and compatibility receipt +in one transaction. If a pre-update `worker_done` already settled the Dispatch, +the adapter reconstructs the matching semantic receipt from the existing +message and settlement. The persisted A settlement is authoritative: the +pinned A reconciler recorded even a `Failed:` subject as completed, so B +returns that original completed result rather than retroactively changing Task +or dependency state. Only a not-yet-accepted B call applies the corrected +failure inference. A conflicting retry fails. + +### `check` + +Legacy check is at-least-once: + +1. a read RPC returns the exact unacknowledged `legacy_direct` message IDs + without changing them; +2. the CLI prints the complete response; and +3. a hidden ack atomically records receipts and marks those exact rows read. + +A cut after read and before ack replays the same IDs. `--peek` and `--all` +remain read-only. + +Version A could mark a message read before losing its response. On adoption, +every eligible read direct message connected to a still-active legacy attempt +and lacking a post-adoption receipt is inserted into a durable recovery cohort +using `legacy_mail_receipts` with `acknowledged_at = NULL`. Legacy check drains +that stable cohort in bounded sequence-ordered pages before ordinary unread +mail. Each page is labeled +`[LEGACY RECOVERY REPLAY — MAY HAVE BEEN SEEN]`, replays until its post-print +ack, and then advances. The cohort never grows after adoption, so every +eligible row is covered without an unbounded response. Settled-at-cutover and +unrelated historical mail do not enter it. + +### `ask` + +Legacy ask is an idempotent mutation followed by a resumable read: + +1. create or find the direct legacy gate/question by verified Dispatch, + normalized question, options, and recipient; +2. atomically commit its message/thread plus operation receipt and return the + stable question ID; +3. wait in bounded read-only slices using that ID; and +4. after printing the answer, hidden-ack that exact answer. + +On first adoption, existing pending decision-gate threads are indexed into the +same semantic identity. A retry resumes them instead of creating another gate. + +### `reply` + +Legacy reply requires the source thread, the verified coordinator principal, +and a unique question owned by the adopted Run. One transaction inserts the +reply, resolves the exact gate, marks the exact source, and completes the +receipt. + +An existing pre-update reply with the same source, principal, and body is +reconstructed as success. A second body for the same source/principal is a +conflict, not another reply. + +### Coordinator and Task commands + +After automatic binding, unchanged Task listing, Task settlement, dispatch, +and gate inspection use the adopted Run. A new attempt receives a current +preamble, capability, launch-token commitment, and current message contract. +No unrelated Task can be created until the migrated coordinator binding is +proven or explicitly taken over. + +## Windows update behavior + +No compatibility mutation holds a DB transaction while waiting. Windows +legacy `ask` commits the question, prints its stable ID and exact resume +command, then exits before a long wait whenever the installed launcher cannot +prove that the executable is replaceable. + +The native packaged launcher sets an internal +`ORCA_WINDOWS_PACKAGED_CLI_LAUNCHER=1` marker for its Electron-as-Node child. +After the DB commit, legacy `ask` writes and flushes the stable question ID and +the exact resume command, then exits with a documented `75` resume-required +status. The command name comes only from the validated inherited +`ORCA_CLI_COMMAND` packaged enum: `orca` for native packaged terminals or +`orca-ide` for packaged WSL. Arbitrary environment text is rejected rather +than rendered. The launcher propagates status 75. No long wait starts on this +path. + +This compatibility path makes the accepted question recoverable without +claiming Windows updater or uninstaller process ownership. Generic executable +drain, replacement, and uninstall behavior remains separate updater +reliability work and requires its own Windows artifact proof. + +## Rendering and authoritative guidance + +Formatting is authority-aware: + +- `[LEGACY COMPATIBILITY]`: live and attested; show only supported commands; +- `[LEGACY RECOVERY REPLAY — MAY HAVE BEEN SEEN]`: one bounded cutover replay; +- `[LEGACY READ-ONLY]`: retained but unactionable; no Reply or Ack hint; and +- current messages: unchanged. + +Update `skill-guides/orchestration.md` and regenerate its bundled source. The +guide explains automatic adoption, exact continuity, the retired scheduler +boundary, proof failures, current retries, and the Windows ask resume fallback. +It must not tell agents to restart a worker whose Dispatch was adopted. + +Formatting cannot use database provenance alone; current liveness and +attestation are runtime facts. Recovery may reveal the exact already-live PTY +once as an inactive background tab. It never creates a PTY or process, writes +input, switches workspaces, focuses, splits, or injects a terminal. + +## Deterministic verification + +### Schema and authority + +- Migrate exact pre-v7, hard-cutover, current, partial, WAL, reset, and fresh + fixtures; preserve IDs and row counts and reuse one adopted Run. +- Assert Task, Dispatch, decision-gate, message, question-thread, and retained + Delivery Run ownership agrees; outstanding legacy Deliveries are fenced. +- Prove current retries in the adopted Run remain current across repeated + migrations. +- Test unique worker/coordinator import from prior hook commitment plus current + live hook, and every forged, stale, wrong-host, wrong-pane, wrong-process, + duplicate-token, duplicate-role, equivalent-pane, and remote-attachment + ambiguity. +- Race a current-runtime hook before adoption and prove the immutable startup + commitment is neither overwritten nor confused with live proof. +- Cover manual coordinators with no `coordinator_runs` row and reject + conflicting candidates from Task, Dispatch, and message provenance. +- Assert all legacy authority failures occur before message/receipt/gate/state + effects while current invalid-capability rejection remains unchanged. +- Assert tokens are absent from RPC logs, errors, CLI output, and orchestration + storage. + +### Exact old behavior and replay + +- Replay the pinned prompt's heartbeat, successful and `Failed:` + `worker_done`, task-only escalation, ask, and consuming check. +- Replay the old formatter's reply command separately. +- Cover every operation once after B and once accepted by A immediately before + the cutover where a durable semantic identity exists, including the bounded + recovery replay for an A check and preservation of A's persisted settlement. +- Prove one B invocation reuses its invocation ID across reconnect, while + separate identical heartbeat/escalation invocations remain distinct. +- Inject real transport cuts after check read, ask commit, reply commit, and + completion commit; prove stable IDs and one receipt/effect. +- Page a recovery cohort larger than one response limit across repeated + disconnects and prove every eligible row appears until ack, then never again. +- Test mixed legacy/current attempts for every send/check/ask/reply route and + prove current Delivery cannot consume legacy direct mail and old coordinator + check only advertises the exact non-consuming current Delivery command. + +### Live two-launch E2E + +The focused renderer/daemon restart regression reconstructs the rc.3-era +orphan artifact in a shared candidate profile: a durable legacy Dispatch, +sleeping provider record, and live daemon PTY with its visual binding removed. +It proves startup restores the exact PID, PTY/incarnation, handle, tab/leaf, +Task, and Dispatch; emits no provider-resume spawn or interruption; preserves +coordinator focus; and remains inert after switching away and back.

A fleet with +hundreds of worktrees can make Orca and the host unresponsive while the scan is active. + +Two independent resource failures are possible: + +- macOS and Linux run recursive `du` processes for several worktrees at once.

Repository discovery and remote scans can +remain concurrent, but every local worktree must acquire the single local slot before invoking +`du` or the portable walker. + +The slot is global to one Resource Manager scan, not per repository. This changes the maximum local +full-tree traversal count from six to one. Cancellation rejects queued admissions and stops the +active child process through the existing `AbortSignal`. + +### Remote fallback admission + +The desktop-side request-by-request SSH fallback runs its traversal inside the desktop main +process, so its budget is charged against Orca's heap rather than the remote host. Repository and +worktree concurrency alone would let six of these traversals hold six independent budgets at once. +A second scan-wide limiter admits at most two, capping aggregate admission at 2 × 64 MiB instead of +6 × 64 MiB. Bulk relay scans stay outside this limiter: their traversal memory lives on the remote +host, one hard capacity per request. + +### Fixed-worker portable traversal + +Use `scanWorkspaceSpaceEntryTree` for desktop local fallback, desktop remote-provider fallback, and +relay fallback scans. The traversal: + +- owns only the configured number of live entry jobs; +- preserves source order and aggregate sizes; +- uses iterative directory frames instead of recursive promise fanout; +- stops on cancellation and removes its abort listener; +- treats unreadable or disappearing entries as partial failures; +- does not follow symlink targets. + +Top-level `du` result processing uses `mapWithConcurrency` so unusually wide workspace roots do not +allocate one live operation per entry. + +### Capacity admission + +Every portable entry is admitted through `WorkspaceSpaceScanBudget` before retention: + +- maximum entries in any one directory listing: 100,000; +- maximum estimated live scan state per worktree traversal: 64 MiB. + +The entry cap is per listing rather than per traversal because only a single directory's width is +fixed by directory shape. A traversal-wide entry counter is charged by every worker holding a +listing at once, so its verdict scales with the configured concurrency: at 48 workers, 48 × 2,100 +files (100,848 entries) was rejected while 100 × 1,500 (150,100 entries, 50% more) was admitted. +Aggregate live retention stays bounded by the 64 MiB byte cap, which all concurrent listings share. + +The retained-byte estimate includes entry name UTF-16 storage plus conservative per-entry object +overhead, and each listing's parent path once. The parent path is charged per listing rather than +per entry because a listing's entries all share a single parent-path string; charging it per entry +multiplied it by the directory's width, so the 64 MiB cap tracked checkout depth instead of live +heap and rejected the layouts above once the worktree path passed ~58 characters. These are +admission limits, not post-allocation observations. + +The budget measures what the traversal is holding **right now**, not what it has ever seen. A +directory listing is charged when admitted and released once every one of its entries has been +dispatched, so the caps bound the widest concurrent frontier rather than total tree size. This +distinction decides real workspaces: a cumulative counter charged an ordinary 76,788-entry Orca +worktree 61.2 MiB of its 64 MiB cap — 4% headroom, and tipping over purely because a longer branch +name lengthens every absolute path. The same worktree peaks between 4 MiB and 8 MiB of live state. + +Neither cap may depend on where a user checks out their worktrees, so the estimate charges each +absolute path once per listing rather than once per entry. A live cap depends only on directory +shape, so it rejects genuinely pathological layouts (one directory holding six figures of entries) +and nothing else. + +Top-level directory enumeration for the `du` path uses the same budget. A capacity error must not +fall through into the portable walker, because that would repeat an already rejected traversal. + +### Failure behavior + +- Desktop local scan: return an unavailable worktree row with the capacity error. `classifyError` + maps `WorkspaceSpaceScanCapacityError` to `unavailable` rather than `error`, because the workspace + is intact and readable, just too large to size safely. The Resource Manager renders that row as + "Unavailable" instead of "Failed". +- SSH relay scan: reject the bulk scan; the desktop provider converts it to an unavailable row. +- Generic `du` failure: use the bounded portable fallback. +- Cancellation: propagate the scan-cancelled error rather than converting it to a row failure. +- Missing or unreadable entries below the capacity limit: preserve existing partial-result + behavior. + +### Platform and workspace parity + +- macOS/Linux: one local `du` at a time; bounded Node fallback. +- Windows: one local bounded Node traversal at a time. +- WSL: retain `getLocalProjectWorktreeGitOptions` and its selected distro for worktree discovery; + UNC/native filesystem traversal uses the same local admission and capacity bounds. +- SSH: prefer the bulk relay scan; both the relay and the request-by-request compatibility fallback + use the shared capacity model. +- Folder workspaces: the synthetic main worktree passes through the same local limiter and scanner. + +## Data Flow + +1. Resource Manager starts one deduplicated scan and creates an abort controller. +2. Repository workers list worktrees with existing host-specific Git options and the scan signal. +3. Remote worktrees continue through provider concurrency. Local worktrees wait for the scan-wide + local slot. +4. POSIX local or relay scans try `du`. +5. Top-level entries are admitted against the scan budget and projected with bounded concurrency. +6. If `du` fails generically, the fixed-worker portable traversal scans within the same limits. +7. Capacity failures become unavailable rows; successful results keep existing compaction and + progress behavior. + +## Alternatives Considered + +### Only reduce `du` concurrency + +This protects local storage but leaves Windows, SSH compatibility fallback, and failed `du` scans +capable of unbounded heap growth. + +### Only add traversal capacity limits + +This prevents OOM but still permits several recursive `du` processes to compete for local storage, +which does not address the observed whole-host stall. + +### Remove the portable fallback + +This would fail Windows scans and POSIX environments where `du -d` is unavailable or errors during +active filesystem churn. + +### Skip dependency and build directories + +This would make Resource Manager under-report the directories users most often want to reclaim. + +## Measurement and Performance Budget + +The deterministic regression measurements are: + +- peak simultaneous local `du` calls across repositories: exactly one; +- peak simultaneous desktop-side SSH fallback traversals across repositories: at most two; +- portable traversal live entry jobs: no more than its configured worker count; +- portable entries in any one directory listing: at most 100,000; +- estimated live portable state: at most 64 MiB per worktree; an ordinary 76,788-entry worktree + peaks between 4 MiB and 8 MiB; +- progress and final row counts remain unchanged for scans below the limits. + +A follow-up diagnostic span should record strategy (`du` or portable), worktree duration, fallback +reason, admitted entry count, estimated retained bytes, and peak local scan concurrency. It must +record counts and identifiers rather than raw paths or directory trees. + +## Test Plan + +- Desktop integration: force the portable path over its entry budget and assert an unavailable row. +- Relay integration: force the portable path over its entry budget and assert a capacity failure on + both the Windows/portable and POSIX `du` entry points. +- Remote fallback concurrency: hold six SSH fallback traversals across two repositories and assert + no more than two run at once. +- Concurrency: start local worktrees from two repositories, hold the first `du`, and assert the + second does not start until the first completes. +- Shared traversal: verify worker peak, source order, exact-limit success, over-limit failure, deep + trees, partial failures, and cancellation cleanup. +- Existing desktop coverage: local results, symlinks, progress, cancellation, WSL routing, SSH bulk + scans, disconnected SSH, `du` timeout fallback, and IPC deduplication. +- Run `pnpm run typecheck` and `pnpm run build`. + +## Rollout + +1.
