Put a shell command's live output back in the order the command printed it. +//! +//! The developer extension streams every non-blank line a shell command prints +//! as a `shell_output` logging notification, and numbers them: `seq` counts one +//! command's streamed lines from 0. The numbering exists because the order is +//! lost on the way here. rmcp hands every incoming notification to a task of +//! its own (`rmcp-0.14.0/src/service.rs`, `tokio::spawn(... handle_notification +//! ...)`), so two adjacent lines race each other into the agent's channel and +//! regularly arrive swapped. The e11 self-test printed `crew --help` with ten +//! adjacent pairs swapped while the recorded tool result, which never passes +//! through that path, was byte-identical to the command's own output. +//! +//! [`ShellOutputOrder`] is the display side of the fix: it releases each tool +//! call's lines strictly in `seq` order and holds a line that arrives ahead of +//! a missing one. It never loses a line — every line it accepts is released +//! exactly once — and it never holds one for long: +//! +//! - the tool call's response releases whatever that call still holds +//! ([`ShellOutputOrder::finish`]), and the end of the turn releases the rest +//! ([`ShellOutputOrder::finish_all`]); +//! - a gap is given up on after [`GAP_GRACE`] or once [`MAX_HELD`] lines wait +//! behind it, because a gap is not always a reordering. The agent's channel +//! drops a notification when it is full (`try_send`), so a burst can lose a +//! line outright, and waiting for it would freeze the live view until the +//! command ends. A line that turns up after its gap was given up on is +//! printed when it arrives, out of order, rather than dropped; +//! - a line with no `seq` (a server from before the numbering) is released at +//! once, exactly as it always was. +//! +//! Lines are keyed by the tool request id the agent attaches to each +//! notification, so two commands running at once never hold each other up. +//!

The desktop clients connect as their own Unix users to an ordinary-user broker on one Linux node. There is no public chat listener, privileged product service, or shared login credential. + +## Build and install + +On the intended Linux architecture, with the repository's Rust toolchain available: + +```sh +cargo build --locked --release -p biorouter-crew +mkdir -p "$HOME/.local/bin" +install -m 700 target/release/biorouter-crew "$HOME/.local/bin/biorouter-crew" +``` + +Each member installs their own verified executable. This command builds only the broker and bridge; it does not require the desktop, a database server, Node, or a container runtime on the cluster. Use the correct target directory if `CARGO_TARGET_DIR` is set. A binary built on another operating system cannot be copied to Linux and used as a Linux executable. + +## First workspace + +In the BioRouter Crew tab, add a connection, expand **Hosting a new workspace?**, and choose **Prepare my hosting identity**. Use that public bootstrap key when starting the broker. Keep the private signer on the desktop. + +```sh +umask 077 +mkdir -p "$HOME/.local/share/biorouter-crew" +"$HOME/.local/bin/biorouter-crew" start \ + --state-dir "$HOME/.local/share/biorouter-crew/lab" \ + --bootstrap-key DEVICE_PUBLIC_KEY_HEX +"$HOME/.local/bin/biorouter-crew" status \ + --state-dir "$HOME/.local/share/biorouter-crew/lab" +``` + +Copy the verified status output into the desktop connection, authenticate through native SSH, and initialize the host identity. Invite colleagues using their Unix UIDs and their own desktop device public keys. Enrollment grants workspace presence; team and channel invitations grant their separate memberships. Preparing again recovers the same unused device after a desktop restart. + +The host's home directory, journal, and device authority remain private to its Unix account. The shared socket accepts connections from other users, but kernel UID and signed requests authenticate every protected operation. The hosting account and host administrator remain trusted with stored content. + +## Operating boundaries + +- Linux local persistent storage is required. Network filesystems, automatic node failover, and incompatible kernel capabilities are explicitly refused. +- Native OpenSSH owns host trust, keys, keyboard-interactive authentication and jump routes. Crew never stores MFA answers or accepts changed host keys automatically. +- Private is the initial connection and workspace mode. Existing restricted content stays restricted after a switch to Public. +- Agent grants select context channels, destination, provider and an optional ordinary-user work directory. Local and remote access share these checks. Unsupported confinement disables execution rather than weakening the grant. +- The broker has explicit journal, state, message and attachment limits. Reaching a quota refuses new mutations and leaves existing reads available. Review the capacity and preservation section of the protocol before deploying a long-lived workspace. +- SSH encryption alone does not establish HIPAA compliance. Institutional endpoint approval, retention, access review, workstation controls and the documented host trust boundary remain necessary deployment considerations. + +See the [protocol and rootless setup contract](../../docs/research/biorouter-crew/protocol-contract.md), [implementation plan](../../docs/research/biorouter-crew/implementation-plan.md), and [acceptance ledger](../../docs/research/biorouter-crew/implementation-status.md).

Joining a workspace by invitation and device code (S3a), compiled only with the +//! `join-by-name` feature, which is on by default since 2026-09-25 (naming design D17). +//! +//! See `docs/research/biorouter-crew/naming-design.md`, "Broker protocol (S3a)", "The device +//! code" and "Security analysis". The host invites an account by `@username`; the joiner's own +//! desktop computes a device code from its saved key and the workspace key it pinned; the host +//! pastes that code to approve; and `auth.join` binds a key **only** when its device code equals +//! the approved one.

The result is +//! cached in `dedupe`, so it never carries a code, key, UID or join ID. +//! - [`project_for_manager`]: the host's `workspace.snapshot` only, as `pending_joins`. +//! - [`on_principal_revoked`]: `enrollment.revoke`, with the revoked principal's UID and +//! username. +//! - [`prune_expired`]: at the start of every mutation (`apply_mutation`, `auth.bootstrap`, +//! `auth.enroll`), so expired joins never count against the cap. +//! - [`on_legacy_enrolled`]: after a successful legacy `auth.enroll` for `uid`. +//! - `hello` advertises `join_by_name_v1` whenever this module is compiled. +//! +//! Account lookups go through `broker.directory` (the [`Directory`] seam), never through libc +//! directly, and only after `broker.manager(..)` has admitted the caller. `enrollment.pending` +//! makes none; `auth.join` makes exactly one, the fresh `by_uid` of check 2. + +use super::*; +use unicode_properties::{GeneralCategory, UnicodeGeneralCategory}; + +/// At most this many joins may be pending at once.

Broker contract for joining a workspace by invitation and device code, slice S3a of +//! `docs/research/biorouter-crew/naming-design.md` ("Broker protocol (S3a)", "The device code", +//! "Security analysis" and "Tests"). +//! +//! Most of this file needs the `join-by-name` feature, which is on by default since 2026-09-25 +//!

A journal in which a join was added and then +//! removed (one top-level `Set [pending_joins]`, one `Remove [pending_joins]`) replays and keeps +//! working on a broker built **without** the feature; the `--no-default-features` run is that +//! build. The feature build pins that the real broker writes exactly those two shapes, so the +//! two runs together cover the downgrade. +//! +//! **The previous broker, for the reviewer.** No released Biorouter carries the Crew broker +//! yet, so the previous binary is the broker as it was before this campaign's naming work +//! (`76b88555`, which predates `pending_joins`, `Workspace.name` and `Device.added_via`). The +//! run, on Linux as an ordinary user with `/etc/machine-id` and a second account `bob`: +//! +//! 1. Extract `git archive 76b88555 crates/biorouter-crew` into a scratch workspace, and link it +//! beside this tree's crate (built with `join-by-name`) into one small harness, renaming the +//! two dependencies (`crew_old`, `crew_new`). Both open the same state directory with +//! `Broker::open`, so both read the real account database, exactly as `serve` does. +//! 2. Alternate the two over one journal: new (bootstrap, a team, invite `@bob` and cancel), +//! old (replay, a mutation, a signed snapshot), new (replay, invite `@bob` again and approve +//! his code, leaving the join pending), old (replay a journal holding a pending join, a +//! mutation), new (Bob's laptop joins by its code), old (replay the `auth.join` record; Bob's +//! device authenticates there too), new (replay everything). +//! 3. Every step must succeed, and the journal must show exactly one `set pending_joins` per +//! first join and one `remove pending_joins` when the last one ends. +//! +//! Measured 2026-09-23 in `rust:1.92-bullseye`: every step passed. A join still **pending** +//! when a host downgrades is ignored by the old broker and comes back unchanged after an +//! upgrade (its patches live on in the journal): a claim then re-checks expiry, the account +//! name and the principal generation, so a stale join fails closed and a valid one completes. +//! +//!

The bridge signs `hello` with a workspace key the tests know, so +//! the daemon's real identity verification runs, and it answers everything else from a +//! per-host scenario file each test writes, logging every frame it receives. That lets a test +//! play a hostile bridge: an answer that carries its own device code, a capability it does not +//! have, a refusal whose words must not reach the person. +//! +//! **Sandboxed.** `test_sandbox` points the Biorouter config root at a throwaway directory, and +//! the ctor selects the development file credential backend under this binary's own fixture +//! directory, so no test touches the operator's keychain, `~/.config/biorouter` or `~/.ssh`. +//! The user-action digest is a process-global `OnceLock`, so the "no key installed" answer is +//! pinned where it cannot race: the routes use the same three-way proof decision as every other +//! person-gated Crew route. +#![cfg(unix)] + +// Redirects this binary's Biorouter data/config/state dirs at a throwaway root before `main`, +// so nothing here can open the developer's real `sessions.db` or Crew profile. +#[path = "../src/test_sandbox.rs"] +mod test_sandbox; + +use axum::{ + body::Body, + http::{Request, StatusCode}, + Router, +}; +use futures::FutureExt; +use serde::{Deserialize, Serialize}; +use serde_json::{json, Value}; +use serial_test::serial; +use std::{ + fs, + panic::AssertUnwindSafe, + path::{Path, PathBuf}, + sync::{Mutex, OnceLock}, +}; +use tower::ServiceExt; + +/// Set only in the fake `ssh` process: the fixture directory it reads scenarios from. +const FAKE_SSH_ROOT: &str = "BIOROUTER_CREW_JOIN_ROUTES_FAKE_SSH"; +/// The user-action key the desktop app would hold; the daemon keeps only its digest. +const USER_KEY: &str = "crew-join-routes-user-action-key"; +/// The host account's UID the invitations pin. +const HOST_UID: u32 = 1000; +/// The joiner's UID as the fake broker reports it in a challenge. +const JOINER_UID: u32 = 1001; +const SOCKET: &str = "/tmp/crew-1000-0123456789abcdef0123456789abcdef/broker.sock"; +/// A device code a hostile bridge slips into its join status.

D-HOST: "Start it for me", one-click hosting. +//! +//! The Host dialog's second step shows the commands that start Crew on the server with this +//! computer's hosting key.

The manual path stays. +//! +//! What keeps this from being a remote shell: +//! +//! - **The command is fixed text.** [`host_start_command`] builds it from two values only, both +//! under a grammar that admits no shell syntax: the workspace name (`[a-z0-9-]`, as the +//! broker's own rule) and the hosting key this daemon prepared (`[0-9a-f]{64}`, read from its +//! own registry by preparation ID, never from the request). Nothing a renderer or an agent +//! writes becomes command text. It is character for character what the dialog shows +//! (`hostStartCommands` in `ui/desktop/src/components/crew/onboarding/joinText.ts`; a test +//! reads that file). +//! - **Only the account the person authenticates as.** It is the login they typed for this +//! workspace, over the same hardened `ssh` the bridge uses (`BatchMode=yes`, strict host-key +//! checking, no forwarding, the same preflight), so it gains no account or privilege beyond +//! theirs, and it never prompts: a server that asks for a password or a code refuses with +//! that classified reason and the person runs the commands themselves. +//! +//! The plan's wording (§16 D-HOST) is "over the already-authenticated SSH transport". At this +//! step there is none: the Host dialog saves the connection, and so first signs in, only at +//! Create, after the start. So the run is a fresh `ssh` to the login the request names, and +//! nothing ties that login to the host setup. That is the same trust the Create step already +//! gives the same field: `POST /crew/connections` takes `ssh_target` from the renderer under +//! the same proof of a person, and its Connect runs `biorouter-crew bridge` over this same +//! hardened, non-interactive `ssh` to it.

D-KEEPALIVE: an idle Crew connection stays up. +//! +//! The broker drops a bridge that sends nothing for 300 s (`serve_client`'s read timeout in +//! `biorouter-crew/src/broker.rs`). Nothing observes while Crew is off screen, so before this a +//! connection that sat idle for five minutes died, the daemon learnt it only when the next +//! request failed, and the person had to press Retry and then Connect (Q2-01, five critics). +//! +//! Two things keep it up, both over what the person already authenticated, and neither skips a +//! gate: +//! +//! - **A heartbeat.** While a bridge is this connection's live one, a task started by the +//! connect sends `hello` over it whenever it has been idle for [`KeepaliveTiming::idle`], well +//! inside the broker's 300 s. The answer is verified exactly as a refresh verifies it (the +//! pinned workspace key and node, over a fresh nonce), so the heartbeat is also a check that +//! the bridge still reaches the workspace it pinned. It needs no device key and writes nothing +//! to the workspace. +//! - **A transparent re-dial.** When a heartbeat finds the bridge gone (this computer slept, +//! the network dropped, the broker restarted), or a request finds it ended or idle past +//! [`KeepaliveTiming::probe_before_use`] before writing anything, the daemon connects again +//! the way Connect does: `BatchMode=yes` over the same SSH settings and control socket, and a +//! freshly verified `hello`. So it never prompts: when SSH needs a password or a code, the +//! re-dial fails with that classified reason, the connection reads disconnected with it, and +//! Sign in is the person's to open. A re-dial never follows a person's Disconnect (or an edit +//! or removal), never runs while a sign-in is pending, and a failure that is not about the +//! network (sign-in, host key, a missing bridge, a workspace that no longer verifies) is +//! final. A network failure is tried again [`KeepaliveTiming::retry_delays`] times, with +//! growing gaps, and then every [`KeepaliveTiming::late_retry_every`] for up to +//! [`KeepaliveTiming::late_retry_for`] (Q3-11: a network that came back after the quick +//! retries left the connection down until someone pressed Connect). The connection shows +//! the real reason all the while. +//! +//! **The retries are armed whoever finds the drop (Q4-01).** The schedule +//! ([`CrewManager::schedule_redials`]) used to be armed only by the keepalive's own re-dial, so a +//! drop that a request found first (Crew's own view, reading the connection while the network +//! was down) retired the bridge, ended the keepalive with it, and left nothing to dial again +//! when the network came back. Now the same schedule is armed, with the same rules, by each of +//! the three ways a drop is found: a heartbeat or an ended bridge the keepalive notices, a +//! request that finds its bridge gone before writing (or whose bridge breaks while carrying it: +//! the request is never sent again, only the connection is dialled), and a person's Connect that +//! fails for a network reason. It is armed under the connection's lifecycle guard, in the same +//! hold as the failure it follows, so a Disconnect can only come after it and always disarms it. +//! Each arming replaces the last one's token, so there is never more than one schedule, and it +//! is never armed for a device whose membership ended ([`MEMBERSHIP_ENDED`]) until a dial +//! succeeds again. +//! +//! **An ended bridge is noticed within [`KeepaliveTiming::ended_check`] (Q4-08).** Between +//! ticks the keepalive looks, every few seconds, at whether its bridge's `ssh` has exited. That +//! is local process state, nothing is sent, and the heartbeat and idle rules are unchanged; it +//! only means a dead bridge reads offline (and is dialled again) in seconds rather than at the +//! next 30 s tick. +//! +//! Only a bridge that is **gone** is dialled again. A heartbeat the bridge carried and whose +//! answer was refused (a different node, a `hello` that lost the v2 signature it had, one that +//! does not verify, the broker refusing it) says nothing about the network: a re-dial would only +//! take a second answer from the same place, and `connect` accepts a v1-only `hello`, so a +//! downgrade the refresh path refuses would be adopted without a word. That refusal is final +//! instead: the bridge is retired with it, and it is left showing. +//! +//! Nothing here re-sends a request whose outcome is unknown: a heartbeat is only ever a +//! `hello`, and a request re-dials only when nothing has been written to the old bridge. +//! +//! **A membership that ended stops everything (Q3-12).** A heartbeat is a keyless `hello`, so +//! it cannot see that the workspace revoked this computer: a revoked device's bridge used to be +//! heartbeated and re-dialled indefinitely, and read `connected`, while every read was refused. +//! Now a person-signed request the workspace refuses because it no longer knows this device +//! (`unauthorized: unknown device`, a device whose account is gone, `principal_revoked`) is +//! identity-final, like a workspace that no longer verifies: the idle re-dial is disarmed, the +//! bridge is retired (so its keepalive ends), and the connection reads disconnected with +//! [`MEMBERSHIP_ENDED`] beside its `last_error`. Nothing dials it again by itself; a person's +//! Connect still may, and verifies from scratch.

Offline: the "SSH connection" is this test +//! binary itself, started by the fake `ssh` in [`FAKE_BROKER`] mode, so nothing opens a +//! socket and CI's loopback-only integration step runs it. +#![cfg(unix)] + +use std::io::{BufRead, Write}; +use std::path::{Path, PathBuf}; +use std::sync::{Arc, Mutex, OnceLock}; + +use async_trait::async_trait; +use biorouter::agents::extension::ExtensionConfig; +use biorouter::agents::{Agent, AgentConfig, AgentEvent, SessionConfig}; +use biorouter::config::paths::Paths; +use biorouter::config::permission::PermissionManager; +use biorouter::config::BioRouterMode; +use biorouter::conversation::message::{Message, MessageContent}; +use biorouter::model::ModelConfig; +use biorouter::privacy::affiliation::{InstitutionId, ModelAffiliation}; +use biorouter::privacy::ProviderTier; +use biorouter::providers::base::{Provider, ProviderMetadata, ProviderUsage, Usage}; +use biorouter::providers::errors::ProviderError; +use biorouter::session::session_manager::SessionType; +use biorouter::session::SessionManager; +use ed25519_dalek::{Signer, SigningKey}; +use futures::StreamExt; +use rmcp::model::{CallToolRequestParams, Tool}; +use serde_json::{json, Value}; +use sha2::{Digest, Sha256}; + +/// Set on the fake `ssh`'s child: this process is the broker, and logs every frame here. +const FAKE_BROKER: &str = "CREW_WORKER_ALLOWLIST_FAKE_BROKER"; + +const CONNECTION: &str = "crew-allowlist-connection"; +const WORKSPACE: &str = "6c6c6c6c-6c6c-46c6-86c6-6c6c6c6c6c6c"; +const CLUSTER: &str = "7d7d7d7d-7d7d-47d7-87d7-7d7d7d7d7d7d"; +const NODE: &str = "8e8e8e8e8e8e8e8e8e8e8e8e8e8e8e8e8e8e8e8e8e8e8e8e8e8e8e8e8e8e8e8e"; +const OWNER_UID: u32 = 10001; +const CHANNEL: &str = "channel-general"; +const RUN: &str = "run-allowlist"; +const INSTITUTION: &str = "ucsf"; + +/// The five things only a person may do, each as a model that ignores the tool's schema +/// would send it. +const HUMAN_ONLY: [(&str, &str); 5] = [ + ( + "enrollment.approve", + r#"{"enrollment_id":"enrollment-mallory"}"#, + ), + ( + "team.add_member", + r#"{"team_id":"team-lab","username":"crew_mallory"}"#, + ), + ( + "channel.add_member", + r#"{"channel_id":"channel-general","username":"crew_mallory"}"#, + ), + ("run.revoke", r#"{"run_id":"run-allowlist"}"#), + ("policy.set", r#"{"mode":"public"}"#), +]; + +/// The allowlist's refusal, as the tool result carries it. +const ALLOWLIST_REFUSAL: &str = "Operation unavailable to a scoped Crew worker"; + +fn workspace_key() -> SigningKey { + SigningKey::from_bytes(&[41; 32]) +} + +fn device_key() -> SigningKey { + SigningKey::from_bytes(&[42; 32]) +} + +fn hex(bytes: &[u8]) -> String { + bytes.iter().map(|byte| format!("{byte:02x}")).collect() +} + +/// Where this binary's sandbox lives, set before `main`. +static SANDBOX: OnceLock = OnceLock::new(); + +/// Before `main`: either be the fake broker (when the fake `ssh` started this binary), or +/// point every process-global store at a sandbox and put the fake `ssh` first on `PATH`. +#[ctor::ctor] +fn broker_or_sandbox() { + if let Some(log) = std::env::var_os(FAKE_BROKER) { + serve_as_fake_broker(Path::new(&log)); + } + let root = tempfile::TempDir::new().expect("a sandbox root").keep(); + if Paths::path_root_override().is_none() { + std::env::set_var("BIOROUTER_PATH_ROOT", root.join("biorouter")); + } + // Crew's development credential backend: device and run keys are files, never the OS + // keychain. + std::env::set_var("BIOROUTER_DISABLE_KEYRING", "true"); + std::env::set_var("BIOROUTER_DEV_PROFILE_ROOT", root.join("profile")); + let bin = root.join("bin"); + std::fs::create_dir_all(&bin).unwrap(); + let exe = std::env::current_exe().expect("this test binary"); + let log = root.join("broker-frames.log"); + for text in [exe.to_string_lossy(), log.to_string_lossy()] { + assert!( + !text.contains('\''), + "a path the fake ssh cannot quote: {text}" + ); + } + let script = format!( + r#"#!/bin/sh +if [ "$1" = "-G" ]; then + printf '%s\n' 'hostname 127.0.0.1' 'port 22' 'stricthostkeychecking yes' \ + 'forwardagent no' 'forwardx11 no' 'permitlocalcommand no' \ + 'clearallforwardings yes' 'nohostauthenticationforlocalhost no' \ + 'tunnel no' 'forkafterauthentication no' \ + 'gssapidelegatecredentials no' 'proxycommand none' \ + 'controlmaster no' 'controlpersist no' 'controlpath none' + exit 0 +fi +for arg; do + if [ "$arg" = "-O" ]; then exit 0; fi +done +exec env {FAKE_BROKER}='{log}' '{exe}' +"#, + log = log.display(), + exe = exe.display(), + ); + let ssh = bin.join("ssh"); + std::fs::write(&ssh, script).unwrap(); + use std::os::unix::fs::PermissionsExt; + std::fs::set_permissions(&ssh, std::fs::Permissions::from_mode(0o700)).unwrap(); + let path = std::env::var("PATH").unwrap_or_default(); + std::env::set_var("PATH", format!("{}:{path}", bin.display())); + let _ = SANDBOX.set(root); +} + +/// The broker's answers, one JSON line per request line, until the bridge closes.

After `"stopped":false`, check that the process is gone before you start again. Data is kept, and members see the workspace as offline. + +## How identity works + +- The broker checks every request: the member is active, uses the UID they joined with, and that UID keeps its username. If not, the command line shows `Account enrollment changed.` and `biorouter crew members` shows `account no longer valid`. Usernames are unique among active members, ignoring case and lookalike letters. +- After you rename an account, remove the old member and invite the new name. Inviting the new name first is refused with `This account joined as @bob and is now @robert…`. +- Remove a member from every workspace before you delete their account. Crew cannot tell apart two people who get the same UID and username. +- Only the host manages membership, the workspace name, privacy and institution, and agents never can. See [Hosting a workspace](hosting-a-workspace.md). +- Removing someone ends every agent's access in the workspace. Their messages, server account and SSH access stay. Inviting them again creates a new member with no earlier teams or channels. + +The host's account, programs running as it and the server's administrators can read everything the workspace stores, including Restricted channels. SSH encryption alone does not make a deployment HIPAA compliant. Your institution decides endpoint approval and access review. + +## Member computers + +- Each member needs the Biorouter app or command line, and the OpenSSH client. +- On macOS and Linux, the app and command line share one background service per profile, which keeps running after the app closes. The command line needs `biorouterd` beside `biorouter`. On Windows it cannot use the service: `Shared Crew daemon IPC is unavailable on this platform`. +- A [managed policy](../security/managed-policy.md) with a hook under `hooks` or `allow_project_hooks: true`, or one that does not parse, blocks agent tasks and chat access with "Crew is unavailable with required managed hooks…" or "…the managed policy could not be loaded…". Messages and files still work. +- Each person also keeps an approval secret. See [Getting started](getting-started.md). + +## Where Crew keeps its data + +| Path | Contents | +|---|---| +| `journal.jsonl` | The whole workspace and every change, appended with chained checksums. | +| `blobs/` | Shared file contents. | +| `writer.lock`, `runtime.json`, `broker.log`, `torn-tail-` | The lock, the broker's details, its log, and any journal line set aside during recovery. | +| `~/.local/bin/biorouter-crew` | The program, in each member's server account. | +| `~/.local/state/biorouter-crew/remote-jobs/` | Records of agent commands, in each member's server account. | +| `~/.config/biorouter/crew/` | On each computer: saved connections, and vault files when used.

Computer paths are macOS and Linux defaults. + +## Upgrade Crew + +Upgrade at a quiet time, because members disconnect while the broker restarts. As the host: + +1. Install the new file beside the old one, and check it: + + ```bash + cd "$HOME/.local/bin" + cp -p biorouter-crew biorouter-crew.previous + install -m 0755 /path/to/new/biorouter-crew .biorouter-crew.new + sha256sum .biorouter-crew.new + ./.biorouter-crew.new --version + ``` + +2. Stop the broker and check for `"stopped":true`: + + ```bash + ./biorouter-crew stop --state-dir "$HOME/.local/share/biorouter-crew/chen-lab" + ``` + +3. Replace the file and start the broker: + + ```bash + mv -f .biorouter-crew.new biorouter-crew + ./biorouter-crew start --state-dir "$HOME/.local/share/biorouter-crew/chen-lab" + ``` + + The `start` line prints `"state":"running"`. + +4. Tell members to choose **Connect to chen-lab** if the workspace shows as offline. Their status row reads "Connected" again. + +The new broker reads the journal as it is. To roll back, work in `~/.local/bin`: + +1. Stop the broker as in step 2 of the upgrade, and check for `"stopped":true`. +2. Run `mv -f biorouter-crew.previous biorouter-crew`. +3. Run `./biorouter-crew start --state-dir "$HOME/.local/share/biorouter-crew/chen-lab"`. It prints `"state":"running"`. + +Members replace their own copy the same way. It takes effect at their next connection. If a member reads that the server "can't let people join with a code yet" or "can't add people directly yet", upgrade the broker. + +After a Biorouter update, each computer's background service stays old until it restarts, because reopening Biorouter on macOS or Linux attaches to the running one. "…needs a newer Biorouter background service…" in the app, or `Restart the shared Biorouter daemon to …` in a terminal, means this. [Replace an old background service](connections-and-troubleshooting.md#replace-an-old-background-service) gives the fix. Stopping the service affects every window and terminal using it. + +## Back up a workspace + +Crew has no export, backup, restore, retention or deletion tools, and never deletes messages or files. Your institution decides backup, retention, deletion and legal hold. To preserve a copy: + +1. Stop the broker and check for `"stopped":true`. +2. Make sure nobody starts it while you copy. +3. Copy the whole state directory to equally private storage, and check the copy with `sha256sum`. +4. Start the broker again. The `start` line prints `"state":"running"`, and members can connect. + +Never edit `journal.jsonl`, because a broker refuses records that fail their checksums. A copy cannot run on another machine (`node_identity_changed`) or account (`host_identity_changed`), and Crew has no failover. The host's account and root can change the journal, so keep tamper resistant audit records elsewhere. + +## Workspace limits + +| Item | Limit | +|---|---| +| Workspace state (live data) | 16 MiB | +| Journal file | 1 GiB | +| Messages, and records kept for retries | 100,000 each | +| Teams, channels | 100, 1,000 | +| Shared files | 1 GiB each, 10 GiB total, 10,000 files | +| Remote references | 10,000 | +| Channels an agent reads | A task: its channel plus 16 more.

Ask your host. | +| `crew_ssh_failed` | SSH or Crew on the server failed, for example because Crew stopped when the server restarted. Ask your host to start it again as in [Server commands](#server-commands), then run `connect`. | + +`auth` says `Signed in, but Crew couldn't start on the server` when that copy is missing, and `terminal could not be attached` when another window is already signing in to this connection. + +## Change or remove a saved connection + +`connections remove` acts at once, with no confirmation prompt. It disconnects, ends every chat's access through that connection, and deletes this computer's device key for the workspace. Your messages stay on the server, and you stay a member, so your old invitation does not bring the workspace back. To use it here again, follow [Add this computer to your existing account](joining-a-workspace.md#add-this-computer-to-your-existing-account), or from a terminal: + +1. Ask the host to run `enroll invite @bob --add-device` and send you the new invitation. +2. Run `connections join-invitation` with it, then `auth` and `join`, as in [Join a workspace](#join-a-workspace). +3. Send the new code to the host.

The output of `connections show` is not valid input. + +## Host a workspace + +In the desktop app, choose **Host a new workspace**, then **Start it for me**, as [Hosting a workspace](hosting-a-workspace.md) describes. From a terminal: + +1. On your computer, run `biorouter crew connections prepare --show-ids` (`enroll prepare` is the same command). Note the public key and the `Preparation ID:`, which only `--show-ids` shows. +2. On the server, in your own SSH session, run the command below. The name is 1 to 40 lowercase letters, numbers and dashes, and starts and ends with a letter or number. Copy the JSON it prints into a file on your computer, such as `lab-start.txt`. + + ```bash + "$HOME/.local/bin/biorouter-crew" start --name lab --bootstrap-key 'PUBLIC_KEY_HEX' + ``` + +3.

Run `biorouter crew auth`, then `biorouter crew workspace bootstrap`, which works once, with the key you gave `start`. It prints `Signed in to lab as @alice.` Members see your display name after you run `profile set 'Alice Chen'`. +5. Run `biorouter crew privacy set-workspace private --institution ucsf`. The institution can never change, so check it before anyone runs an agent. The command prints a line such as `Workspace privacy: Private for everyone · institution ucsf · policy epoch 2`. + +`workspace show` lists its privacy, people, teams, channels, invitations and agent grants. `workspace rename NAME` (host) keeps the history and grants. + +## Let people into the workspace + +Only the host runs `enroll` commands. + +1. Run `biorouter crew enroll invite @bob`. Crew checks that this server account exists and prints an invitation message. Send the whole message to Bob. It holds no secret. +2. When Bob sends his code, run `biorouter crew enroll approve @bob 7QK2-M9XA-3JTP-WZ4D`. Case, spaces and dashes do not matter. It prints `Code saved. @bob joins when their computer confirms the same code.` +3. Bob is in only when his `join` prints `You're in lab.` + +`enroll pending` lists who is waiting. If you mistyped a code, Bob's `join` reports a mismatch and `enroll pending` warns under his row. Run `enroll approve` again with `--replace`. Approve only a code the person sent you. + +- `connections invitation --for @bob` prints the invitation again. `enroll invite @bob --add-device` lets a member add another computer. `enroll cancel @bob` withdraws an invitation. +- An invitation lasts 24 hours. Inviting again replaces it. At most 100 people can wait at once. +- `enroll revoke @bob` removes a member with all their computers, and asks you to type `@bob` again. In a script, add `--confirm @bob`. It ends every agent grant in the workspace. A removed person invited again starts with no teams or channels. + +### Tokens for older servers + +A server whose `biorouter-crew` cannot join by code needs the older token path. Its commands (`enroll invite --uid UID --public-key HEX`, then `enroll accept`) are hidden from `--help`, and a token works once, within one hour. See [Enroll with a token](../research/biorouter-crew/cli-guide.md#enroll-with-a-token-older-versions), and update the server when you can. + +## Manage your profile, teams and channels + +| Command | Notes | +|---|---| +| `profile show` | Your name and enrolled computers. | +| `profile set 'Bob Lee' --avatar 'BL'` | Up to 12 characters of initials or emoji.

Try again later.` Wait ten minutes. + +## Add people to teams and channels + +- `members` lists everyone, marking `you`, `host`, `former member` and `account no longer valid`. +- `members add @bob --team TEAM` (team owner or host) adds Bob to the team and its `#general`, and to each `--channel` of that team. Bob does not need to accept. +- Without `--team`, each `--channel` must be one you own, in a team Bob is already in. The host may name any channel there. + +| Task | Command | +|---|---| +| Invite someone, who then accepts (team creator or channel owner) | `invites create @bob --team TEAM` or `--channel CHANNEL` | +| Accept an invitation | `invites list`, then `invites accept [TEAM or TEAM/CHANNEL]` | +| Remove someone from a channel (channel owner) | `remove-member CHANNEL @bob` | +| Hand over a channel (owner, then Carol) | `ownership offer CHANNEL @carol`, then `ownership accept CHANNEL` | + +A channel invitation needs the person in its team first. `invites accept` exits with `1` when nothing is pending. Add `--former` to `remove-member` for someone who left the workspace. After a handover, the previous owner leaves the channel. + +## Post and read messages + +- `send methods --text 'Ready.'` posts under your name. `--input FILE` reads the text from a file, or `-` for standard input. `--attachment ID` and `--reference ID` add files and can repeat. +- `history methods --latest` shows the newest 100 messages. Without `--latest`, it starts from the oldest. `--limit` takes 1 to 200. With `--show-ids`, it ends with a `Cursor:` line to pass to `--before` or `--after`. +- `search methods 'qPCR'` finds messages in one channel, in any case. +- `watch methods` prints messages as they arrive. Ctrl+C stops it without cancelling tasks. If the daemon ends it, for example because you lost access, it prints why and exits with `1`. + +Crew sends no system notifications, so keep a `watch` running to follow a channel. Message limits are in [Messages and files](messages-and-files.md). + +## Share files and server paths + +Uploading does not post. You upload, then attach: + +1. `biorouter crew --show-ids files upload methods ./counts.csv` prints the transfer ID. +2. `files watch TRANSFER_ID` follows it to `Transfer Ready.` +3. `--show-ids files status TRANSFER_ID` shows the `Attachment ID:`. +4. `send methods --attachment ATTACHMENT_ID` posts it, and prints `Posted to #methods.` + +To download, get the ID from `history methods --latest --show-ids`, then run `files download ID --output ./counts.csv`. Add `--overwrite` to replace a file. + +- `files pending` lists transfers. `files pause ID` pauses one, and `files resume ID FILE` resumes it with the original file. +- `files forget ID` removes a record. For an unfinished download, add `--file PATH` to delete the partial file. +- `files watch` exits with `0` however the transfer ends, so read the last state: `Ready`, `Saved`, `Paused`, `Failed` or `Not confirmed`. Ctrl+C leaves the transfer running. + +Crew refuses to save into a folder that is not yours or that other accounts can change, or into a credential or settings folder. It refuses to upload files that look like credential stores. Size limits are in [Administration](administration.md). + +To share a server path without uploading it, run `--show-ids files reference methods /project/results --label 'Results'`, then `send methods --reference ID`. Crew does not check the path. `files show-reference ID` shows one. + +## Run an agent task + +A task runs your own AI agent on a prompt, lets it read the channel, and posts its result there. + +```bash +biorouter crew tasks start methods --input ./prompt.txt \ + --provider PROVIDER --model MODEL --allow-posting +``` + +- Give the prompt with `--text` or `--input`. `--allow-posting` is required. +- `--provider` is the name in your Biorouter configuration. +- Each `--context-channel CHANNEL` adds a channel to read, up to 16. +- The task's access lasts one hour. +- In a Private workspace, the model must be approved for the workspace's institution, or run locally. See [Agents and chat access](agents-and-chat-access.md). +- The result ends with a line naming the shared files it read, if any. + +`tasks list --show-ids` shows each task and its chat session, and `tasks show ID` shows one. `tasks watch ID` follows one and exits with `0` at every end state, so read the last: `Done`, `Couldn't finish`, `Stopped`, `Interrupted`, `Outcome unknown` or `Stop not confirmed`. Ctrl+C stops watching, not the task. + +`tasks cancel ID` stops the task on your computer and revokes its access, but cannot confirm that a process on the server ended. If the workspace cannot be reached, it exits with `1` and gives a `--request-id` to retry with. + +## Give a chat access to Crew + +The desktop app does this with `/crew`, as [Agents and chat access](agents-and-chat-access.md) explains. From a terminal, find the chat's session ID with `biorouter session list`. The chat must be open in the shared daemon, in the desktop app or a terminal chat, and idle. + +```bash +biorouter crew grants grant SESSION_ID methods --context-channel analysis-lab/raw-data +``` + +The first channel is where the chat posts. Each `--context-channel` adds one to read, up to 20 channels in all. `grants list` shows each chat and task with access, its state and time left. `context SESSION_ID` shows one grant's channels. + +Some workspace changes end every grant and task in the workspace. `grants list` then shows `Ended: Crew settings changed`, and you grant access again. [Why settings changes end access](agents-and-chat-access.md#why-settings-changes-end-access) lists the changes. + +`grants revoke SESSION_ID` exits with `0` only when the workspace confirms. After `Stopped on this device ...` (exit `1`), the chat already cannot use Crew, and Biorouter confirms later by itself. `Not revoked` means the chat still has access, so retry. A revoke does not prove that a command already running on the server stopped. + +To use a terminal chat: + +1. Run `biorouter session --shared-daemon --no-start --create-only`. It prints the chat's session ID. +2. Run `grants grant SESSION_ID methods`. `grants list` then shows the chat as `Active`. +3. Open the chat with `biorouter session --shared-daemon --no-start --resume --session-id SESSION_ID`, or send one prompt with `biorouter run` and the same options plus `--text`. The chat opens in your terminal, or `biorouter run` prints its reply. + +Without `--shared-daemon`, the chat cannot use a grant. + +## Privacy settings + +`privacy show` prints the privacy, institution and policy epoch of your connection and of the workspace, and each channel's classification. + +- `privacy set-personal private --institution ID` or `public` changes how this computer treats the workspace. +- `privacy set-workspace private` or `public` (host) changes the workspace's privacy. `--institution ID` confirms its institution, which never changes. + +> **Warning.** `set-personal public` and `set-workspace public` act at once, with no typed confirmation. The desktop app asks you to type the workspace name first. + +An institution ID is 1 to 64 lowercase letters, digits, `_` or `-`. Changing the workspace's privacy ends every agent grant. Switching to Public never exposes earlier Private content. See [Privacy and security](privacy-and-security.md). + +To stop a script when the policy changed after it checked, pass the epochs from `privacy show` to `--expected-policy-epoch` and `--expected-workspace-policy-epoch`. For posts and file transfers, use `--expected-mode private`. + +## Retry after an uncertain result + +If a change may have reached the workspace but the answer was lost, the error ends with `Retry safely with --request-id ID`. Run the same command again with that option. The workspace does not apply the change twice. A clear refusal never shows this line. + +An ID is 1 to 128 letters, digits, `_` or `-`. Use a new ID for a different change. To continue a transfer, use `files resume`, not a new upload. + +## Recover after a restart + +After your computer or the daemon restarts, check in this order: + +1. Run `daemon status`. Any command starts a missing daemon. +2. Run `credentials unlock` if you use the vault. +3. Run `status`. Run `auth` or `connect` for a `Disconnected` connection. +4. Run `files pending`, `tasks list` and `grants list`. +5. For a task in `Interrupted`, `Outcome unknown` or `Stop not confirmed`, read its channel before you start it again. Repeat `tasks cancel` if the message asks. + +If a command reports a changed key or a daemon it cannot verify, find out why before you connect. Do not replace keys or files to silence it. + +## Workspace refusals + +Workspace refusals are plain sentences that name the fix, with the code in JSON as `broker_code`.

In the window "Sign in to {server address}", wait for the server's question. +2. Type your password and press Enter. The characters do not appear. +3. If the server asks for a verification code, type it and press Enter. +4. If the server lists numbered options, such as "Passcode or option (1-3):", type a number and press Enter.

Your computer keeps the keys it trusts in its known hosts file, `~/.ssh/known_hosts`. Crew connects only to a server whose key is there, and checks that the workspace key matches your invitation. Crew never adds a key for you. A failed check shows "Can’t verify server" and one of three screens. + +### An unverified server + +"Can’t verify {server address} yet" means the server's key is not in your known hosts file. This is normal the first time on each computer. + +1. Ask your IT team for the server's fingerprint. It starts with `SHA256:`. +2. Follow [Verify the server on this computer](joining-a-workspace.md#verify-the-server-on-this-computer). **How do I verify it?** offers **Open a terminal here**. If terminals are new to you, ask IT to help. +3. Choose **Try again**. Crew connects, and the Sign in window opens if the server asks. + +### A changed server identity + +"{server address}’s identity changed" means the server was rebuilt, or another machine is answering in its place. Treat it as a security problem until IT says otherwise. + +1. Choose **Copy details for IT**, and send the details to IT. Do not connect until IT confirms the change. +2. Remove the old key, or ask IT to. In a terminal, type `ssh-keygen -R lab.example.edu` with your server's address, or `ssh-keygen -R '[lab.example.edu]:2222'` for another port. +3. Choose the workspace name, then **Reconnect**. Expect "Can’t verify {server address} yet". +4. Follow [An unverified server](#an-unverified-server) with the new fingerprint. + +### A different workspace + +"This isn’t the workspace you joined" means the server answered with a different workspace key. **Connection settings…** on that screen shows your server. + +1. Choose **Copy details**. "Copied" appears beside the button. +2. Paste the details into a message to your host, and send it. +3. Wait for your host to explain what changed. If the workspace was created again, your host sends you a new invitation. Otherwise, when your host says the server is fixed, choose **Reconnect** in the workspace menu. The status row reads "Connected". + +## Crew missing from your server account + +"Crew isn’t set up for your account on {server address}" in the main area means your own server account has no `~/.local/bin/biorouter-crew`. [Install Crew in your server account](joining-a-workspace.md#install-crew-in-your-server-account) says who can install it and how. + +1. Install it yourself, or copy the ready message on the screen and send it to IT, or to your host to pass on. +2. When it is installed, choose **Try again**.

A wrong value gets a note under its field. **Workspace details** copies IDs that support staff may ask for. + +Choose **Save connection**. If you changed something, Crew disconnects the workspace, so choose **Connect to {workspace}** afterwards. Chats with Crew access on that server lose it.

The `scp` line may ask for your password or code, then prints a progress line that ends at 100%. + + - For a port other than 22, start the `scp` line with `scp -P 2222`, with a capital P and your port. + - For a jump host, start the `scp` line with `scp -J gateway.example.edu`, with its name. + +4. In the window signed in to the server, run this line. It takes the Crew file out of the package without installing it, and prints nothing when it works. If you see `dpkg-deb: command not found`, ask IT for the file. + + ```bash + dpkg-deb --extract biorouter-cli_1.91.2_amd64.deb staging + ``` + +5. In the window signed in to the server, type this line with the file's full path on the server, and press Enter. After step 4, the path is `$HOME/staging/usr/bin/biorouter-crew`, as below. Otherwise, use the path from step 1, such as `/usr/bin/biorouter-crew`. + + ```bash + VERIFIED_BINARY="$HOME/staging/usr/bin/biorouter-crew" + ``` + +6. Copy these three lines, paste them into the same window, and press Enter. + + ```bash + mkdir -p "$HOME/.local/bin" + install -m 0755 "$VERIFIED_BINARY" "$HOME/.local/bin/biorouter-crew" + "$HOME/.local/bin/biorouter-crew" --version + ``` + +When the install worked, the last line prints the version, such as `biorouter-crew 1.91.2`. For other ways to get the file, see [Get a verified file](administration.md#get-a-verified-file). + +## Host the workspace + +On the first Crew screen, choose **Host a new workspace**. If you already have a workspace: + +1. Choose its name at the top of the sidebar. +2. Choose **Add a workspace**. +3. Choose **Host a new workspace…**. The dialog "Host a new workspace" opens. + +The dialog has three steps: Name, Start and Create. + +### Name the workspace + +1. In **Workspace name**, type a name, such as `Wong Lab`. Crew shows it as "Your workspace: wong-lab". Anyone who can sign in to the server can see it, so leave out patient and sample IDs. +2. In **Your server login**, type your login, such as `alice@hpc.example.edu`, or the server's short name from your SSH settings. +3. Under **Privacy**, keep **Private** or choose **Public**. With Private, type your short ID in **Institution** if it is empty. +4. Optional: fill in **Your agent on {server}** ([Agents and chat access](agents-and-chat-access.md)), and **Advanced** if IT gave you a port, an identity file or a jump host. +5. Choose **Continue**. Biorouter makes a hosting key, so only this computer can create the workspace. The dialog moves to step 2, Start. + +The Privacy choice sets only your own connection. Every new workspace starts "Private for everyone". + +### Start Crew on the server + +Step 2 shows four commands that make a private folder, start Crew and print its details. The key in them is public. To change the name, choose **Back**. + +1. Choose **Start it for me**. The box "What the server printed" shows the output. +2. When Crew has started, the dialog moves to step 3 by itself. + +Biorouter runs exactly the commands shown, as you, and never answers a password or code prompt. **Stop** ends a run. Closing the dialog does not stop the commands on the server. + +#### Run the commands yourself + +Use this when **Start it for me** cannot sign in, or fails. + +1. Choose **Run it yourself in a terminal**, then **Open a terminal here**, or use your own terminal. +2. Paste the `ssh` command shown there into the terminal, and press Enter. Check the fingerprint if asked, and type your password or code. +3. Choose **Copy** beside the start commands, paste them into the terminal, and press Enter. +4. Copy all the output, including the whole line from `{` to `}`, into **Paste what it printed**. +5. When Crew shows "Found {workspace} on {server}", choose **Continue**. The dialog moves to step 3, Create. + +#### If starting does not work + +A warning appears, and **Run it yourself in a terminal** opens. + +| Message starts with | What to do | +|---|---| +| "Crew isn’t installed on {server} yet" | Do [Install Crew on the server](#install-crew-on-the-server), then try again. | +| "Crew on the server said:" | Send it to IT, with [Storage requirements](administration.md#storage-requirements) for `unsafe_storage` or `unsupported_storage`, or [Machine identity](administration.md#machine-identity) for `node_identity_unavailable`. | +| "This computer hasn't connected to the server before" | Do [Check which way you will start Crew](#check-which-way-you-will-start-crew), then try again. | +| "The server's identity changed" | Stop and contact IT. | +| "…needs a newer Biorouter background service" | See [Replace an old background service](connections-and-troubleshooting.md#replace-an-old-background-service). | +| "Biorouter read the workspace but not every detail it needs" | From the last output line, copy `socket`, `workspace_id`, `host_uid` and `workspace_public_key` into **Socket path**, **Workspace ID**, **Host user ID** and **Workspace key**. | +| Any other message | Do what it says, or run the commands yourself. | + +### Create the workspace + +1. In step 3, note the workspace **Fingerprint**. People you invite may ask you to read it out. +2. Choose **Create workspace**. Crew calls this computer the workspace's "first admin device": its key is what lets you act as host ([Limits of the host role](#limits-of-the-host-role)). +3. If the server asks for a password or a code, type it in the Sign in window. + +When it worked, the dialog asks about your institution, as described next, or closes and shows the checklist. + +If Create fails, choose **Create workspace** again, or see [Connections and troubleshooting](connections-and-troubleshooting.md). If you closed the dialog too early, choose **Finish creating…** on the "Finish creating {workspace}" card. + +## Mark the workspace with your institution + +After Create, if Crew knows your institution, the dialog asks "Mark {workspace} as a {institution} workspace?". Until the workspace has one, people can chat and share files, but agents cannot work there. + +- **Mark as {institution}** sets it permanently. For another institution, host a new workspace. +- **Not now** leaves it for later. + +To set it later: + +1. Choose **Set institution to {institution}…** in the checklist, in the note above the message box, or in **Privacy…** in the workspace menu. +2. Choose **Set {id} permanently**. Enter cancels. + +The **Institution** row in **Privacy…** now shows it instead of "Not set". **Not now** on the note hides the note on this computer. + +If Crew says "Add your institution in Connection settings first.": + +1. In **Connection settings…**, choose **Private**, and fill in **Institution**. +2. Choose **Save connection**. +3. Set the institution again, from step 1 above. The **Institution** row shows the short ID. + +## Get the workspace ready + +When the Host dialog closes, the checklist "Get {workspace} ready" appears. Work from the top. + +1. In "Your name: Use “{name}”?", choose **Use**, or **Edit…** to change it. Do this before you invite anyone, because an invitation carries your name as it was then. The row appears when your server account has a full name. +2. Choose **Set institution to {institution}…**, as described above. +3. Choose **Create team**, type a **Name** of up to 64 characters, such as `Analysis Lab`, and choose **Create team**. See [Team name rules](teams-channels-and-people.md#team-name-rules). + +The team appears with its `#general` channel, which you own, and the checklist closes. From then on, invite people with **Invite people to {workspace}…** in the channel's welcome block or the workspace menu. + +## Invite people + +Each person first needs Crew in their own server account ([Install Crew in your server account](joining-a-workspace.md#install-crew-in-your-server-account)). + +1. Open the workspace menu and choose **Invite people to {workspace}…**. +2. In **Username**, type the person's login on the server, such as `crew_jack`, not their name. +3. Choose **Invite**, and check that the result names the right person. +4. Choose **Copy** under "Send {first} this invitation:". Send the message by email or chat, with the server's `SHA256:` fingerprint, which each person checks once ([Verify the server on this computer](joining-a-workspace.md#verify-the-server-on-this-computer)). +5. Choose **Invite another**, or **Done**. The person appears under "Waiting to join" in the sidebar, marked "invited". + +An invitation is for one person and expires after 24 hours. Inviting the person again replaces it. The message holds no secret. + +To add another computer for an existing member, turn on **Add another device for @{name}** and choose **Invite**. + +If the person sees "Crew isn’t set up" and the server already has a copy in `/usr/bin`, which does not count, send them or IT the lines under **If {first} sees “Crew isn’t set up”**. They run in the person's own account. Then the person chooses **Try again**. + +## Let people in + +When the person joins, their Biorouter shows a code of 16 letters and numbers, such as `7QK2-M9XA-3JTP-WZ4D`, which they send you. It lets in only their computer. + +1. In the sidebar, under "Waiting to join", choose **Let in…** beside their name. +2. Paste the code into **Code from {first}**. Use only a code that came from that person. +3. Choose **Let {first} in**. The dialog shows "Code saved". +4. Wait for "{first} joined {workspace}", which appears when their computer checks in. +5. Under **Channels in {team}**, tick channels, and choose **Add to {team}**. The dialog shows "Added {first} to {team}." A person in no team sees no channels. + +"Code saved" does not mean the person has joined. The fingerprint in the dialog is not the code. The code field accepts dashes, spaces and lowercase, reads I and L as 1 and O as 0, and refuses U. + +If you closed the dialog before step 5, choose **Add to a team…** on the person's row under "Joined, not in your teams". + +Only you see "Waiting to join". Its rows read "invited", "Code entered" or "Invitation expired". + +After "Invitation expired", choose **Invite again…** on the row, and follow [Invite people](#invite-people) from step 2. + +To cancel an invitation: + +1. In the workspace menu, choose **People…**. +2. On the person's row under "Waiting to join", choose **Cancel invitation**. +3. At "Cancel @{username}’s invitation?", choose **Cancel invitation**. The row leaves "Waiting to join". + +### If a computer showed a different code + +"A computer trying to join as @{username} showed a different code" means you mistyped the code, or another computer tried to join as that person. + +1. Check the code with the person directly. +2. Choose **Let in…** on their row, or **Enter the code again**. +3. Enter the code they sent, and choose **Replace code**. The dialog shows "Code saved" again. Continue from step 4 of [Let people in](#let-people-in). + +Never approve a code you did not get from the person. "@{username} has no pending invitation" means the invitation expired or was cancelled. Invite them again. + +## Add people to teams and channels + +You can add members to teams and channels someone else owns. The person does not need to accept, and must be in a team before joining its channels. To add people to someone else's channel: + +1. In the sidebar, point at the team, choose **⋯**, then **Add people to {team}…**. +2. Tick the people, and the channel under **Also add to**. +3. Choose **Add**. The dialog shows "Added {people} to {team}." and the channels they can now see. Choose **Done**. + +The team dialog lists only people not in the team yet. To add someone already in the team to a channel you do not own, use a terminal ([Add people to teams and channels](command-line.md#add-people-to-teams-and-channels)): + +1. Open a terminal on your own computer. +2. Run `biorouter crew members add @bob --channel '#methods'`. +3. Type your approval secret. It prints "Added. @bob can now see #methods." + +## Manage the workspace + +In the workspace menu, **People…**, **Privacy…** and **Agent access…** open Workspace settings once the connection is verified. Several changes below end every agent's access ([Why settings changes end access](agents-and-chat-access.md#why-settings-changes-end-access)). + +### Rename the workspace + +1. In Workspace settings, open **General** and choose **Rename…**. +2. Type the new name in lowercase letters, numbers and dashes, up to 40 characters. +3. Choose **Rename**. The dialog closes, and the new name appears at the top of the sidebar. + +A rename keeps history, invitations and agent access. The server folder keeps the original name. + +### Remove someone from the workspace + +1. In **People…**, point at the person's row, choose the options button (three dots), then **Remove from {workspace}…**. +2. Type their username exactly, with the same capitals. +3. Choose **Remove from {workspace}**. Enter does not confirm. The person's row leaves **Members**. + +The person loses the workspace on every computer and sees "You’re no longer in {workspace}". Their messages stay, marked as from a former member. Removing someone from one channel is the channel owner's task. + +### Change the workspace privacy + +In **Privacy…**, the **Workspace** row reads "Private for everyone", the default, or "Allows Public". + +To allow Public: + +1. Choose **Allow Public…**. +2. Type the workspace name, and choose **Allow Public**. The **Workspace** row reads "Allows Public". + +To make it Private again: + +1. Choose **Make Private for everyone…**. +2. Choose **Make Private for everyone**. The **Workspace** row reads "Private for everyone". + +See [Privacy and security](privacy-and-security.md#change-the-workspaces-privacy-host-only) for what each setting allows. + +### Limits of the host role + +You cannot hand the host role to someone else, or be removed. You cannot transfer, rename or archive another person's channel. You cannot start, stop or approve another person's agent, act as them, or see their password, codes or device keys. + +> **Warning.** Only your own computers can act as host, through their device keys. Never remove the workspace from your only computer, because nothing can restore the host controls. + +To add a second computer: + +1. Invite your own username with **Add another device for @{username}** turned on. +2. [Join](joining-a-workspace.md) on the second computer with that invitation. +3. Let it in from this computer with the code it shows. + +The second computer opens the workspace and can act as host too. + +## After the server restarts + +Crew does not start by itself, and members see "{workspace} is offline". If you have not used a terminal, ask IT to do this as your account. + +1. Open Terminal (press Command and Space, type Terminal, and press Return), and sign in with `ssh` and your server login. +2. Run `ls "$HOME/.local/share/biorouter-crew"`. It lists one folder per workspace, under the workspace's original name, such as `wong-lab`. +3. Type this line with that folder name, and press Enter. + + ```bash + NAME=wong-lab + ``` + +4. Copy this line, paste it, and press Enter. Do not add `--name`. + + ```bash + "$HOME/.local/bin/biorouter-crew" start --state-dir "$HOME/.local/share/biorouter-crew/$NAME" + ``` + +5. `"state":"running"` in the output means Crew is running. For `"state":"starting"`, wait a few seconds, then run the line again with `status` in place of `start`. +6. Tell members to choose **Connect to {workspace}**, and do the same in your own Biorouter. + +The status row under the workspace name reads "Connected" again. Starting again keeps the workspace, its members, keys and history. To stop Crew, see [Stop the broker](administration.md#stop-the-broker). + +## Less common situations + +### Invite someone whose Biorouter is older + +If the person's Biorouter, or Crew on your server, is too old for codes, or Crew asks for an enrollment token: + +1. In the Invite dialog, choose **Other ways to invite (older Biorouter)**. +2. Paste the person's join request, and type their user ID, which `id -u {username}` prints on the server. +3. Choose **Create invitation**. The hidden token appears, with "It works once and expires in an hour." +4. Choose **Copy**, and send the token. The button reads "Copied". + +The person follows [Join with a token on an older server](joining-a-workspace.md#join-with-a-token-on-an-older-server). + +### An older Crew on the server + +- In the Let in dialog, **Add to {team}** reads **Invite to {team}**, and the person must accept. **Add to a team…** under "Joined, not in your teams" also sends an invitation.

Do this once per server on each computer. + +1. Get the server fingerprint. It starts with `SHA256:`. Your host may have sent it with the invitation. If not, ask IT. If IT gave you a jump host (a server you pass through first), ask IT for its fingerprint too. A server fingerprint is neither the workspace fingerprint nor your code. +2. Open a terminal. On a Mac, press Command and Space, type Terminal, and press Return. Crew's "Can’t verify" screen also offers **How do I verify it?**, then **Open a terminal here**. +3. Type `ssh bob@lab.example.edu` with your username and server, and press Enter. + - For a port other than 22, add `-p` and the port: `ssh -p 2222 bob@lab.example.edu`. + - For a jump host, add `-J` and its name: `ssh -J gateway.ucsf.edu bob@lab.example.edu`. + - If you do not know the server or its port, paste the invitation in the Join dialog (steps 1 to 3 of [Join from the Biorouter app](#join-from-the-biorouter-app)). The server is the name after "on" in the summary. Choose **Advanced**: the grey number in **Port** is the port. Choose **Cancel**. Nothing is saved. +4. Read the answer: + - "Are you sure you want to continue connecting", after a `SHA256:` value: go to step 5. + - A password prompt, or the server's prompt, such as `bob@lab:~$`: the server is already verified. Press Ctrl+C at a password prompt, or type `exit` at the server's prompt. + - "Could not resolve hostname": check the spelling of the server name, or ask IT. + - "timed out" or "Connection refused": connect to your VPN (the app that connects you to your institution's network), check the port, and try again. + - "Permission denied": ask IT which login or key to use. + - "REMOTE HOST IDENTIFICATION HAS CHANGED": stop, and send the whole message to IT. When IT confirms the change, remove the old key (step 2 of [A changed server identity](connections-and-troubleshooting.md#a-changed-server-identity)), and start again at step 3. +5. Compare the `SHA256:` value with the one you got for that host, character by character. With `-J`, SSH asks about the jump host first, then the server. If a value differs, type `no` and tell IT. +6. If it matches, type `yes` and press Enter. SSH prints "Permanently added … to the list of known hosts." If SSH then asks about the next host, repeat step 5. +7. Sign in with your password or code. The terminal does not show a password. Then type `exit`. +8. In Crew, choose **Try again**, or join as below. + +Typing `yes` is the step Crew's help calls adding "the full key". Crew may then ask for your password again. + +### Install Crew in your server account + +Crew needs its server program at exactly `~/.local/bin/biorouter-crew` in your own account on the lab server. Your host's copy does not count for you, and neither does a copy elsewhere, such as `/usr/bin/biorouter-crew`. Without it, Crew shows "Crew isn’t set up for your account on {server}". + +You install it yourself, signed in as yourself, or IT does. A host with an ordinary account cannot install it in your account. That screen says it is installed "usually by your host or IT team", so a host without administrator rights passes your request to IT. + +To install it yourself, follow [Install Crew on the server](hosting-a-workspace.md#install-crew-on-the-server) with your own login. Its steps 5 and 6 are the lines under **Install it yourself** on the "Crew isn’t set up" screen. Type the first of those lines yourself, because **Copy** on that field also copies its placeholder path. When the last line prints the version, Crew is installed. If Crew already shows "Crew isn’t set up", choose **Try again** there, and Crew connects. + +## Join from the Biorouter app + +The invitation is a message with a line that starts `brcrew1:`. It holds no secret. Nobody can join with a copy alone. + +1. Open Biorouter. On a Mac or Linux computer, type your approval secret when Biorouter asks ([The approval secret](getting-started.md#the-approval-secret)). +2. Choose **Crew** in the left sidebar, then **Join a workspace**. If you already have a workspace, choose its name at the top of the Crew sidebar, then **Add a workspace** and **Join a workspace…**. +3. Paste the whole message into **Invitation from your host**. The box folds to "Invitation read", and a summary appears. **Edit** reopens the box. +4. Check that the summary names the right workspace and host, for example "Hosted by Alice Chen (@alice) on lab.example.edu". If not, choose **Cancel**. +5. Check **Your username on lab.example.edu**. It is your server login, not your Slack name or email. +6. If Crew asks you to "Choose which AI models may work here", ask your host, then [choose](#which-ai-can-read-the-workspace). +7. Leave **Your agent on lab.example.edu** and **Advanced** alone unless your host or IT said otherwise. +8. Choose **Join chen-lab**. If the server asks for a password, see [Sign in to the server](connections-and-troubleshooting.md#sign-in-to-the-server). + +The card with your code appears. Crew finishes the join later without asking again. If a message appears instead, see [When joining does not work](#when-joining-does-not-work). To join from a terminal instead, see [Join a workspace](command-line.md#join-a-workspace). + +### Check the invitation fingerprint + +Choose **Check this invitation (optional)** to see the workspace fingerprint. Ask your host to read the "Fingerprint" row in their workspace menu. If the two differ, do not join. You never send the fingerprint. + +### Which AI can read the workspace + +**Private** means "Only private and institution-approved models". **Public** means "Public models allowed for public-safe work". The choice does not change who sees you or what you read. A Private workspace blocks public models whatever you choose. See [Privacy and security](privacy-and-security.md). + +To change it: + +1. Choose **Advanced**, then **Change which AI can read chen-lab…**. +2. Choose **Private** or **Public**. For Private, type your institution's short ID, such as `ucsf`, in **Institution**. It must match your host's, so ask your host if you do not know it. +3. Choose **Done**. The choice folds into one line, such as "Which AI can read chen-lab: private, ucsf-approved models only". + +### Your agent on the server + +**Your agent on lab.example.edu** is off by default. To let your Biorouter agent read and write files in a server folder, choose it and type the folder's full path, such as `/home/bob/project`, in **Remote work folder**. **Let my agent run commands in this folder** also lets it run commands there. Change both later in **Connection settings…**. See [Agents and chat access](agents-and-chat-access.md). + +### Advanced server connection details + +Use **Advanced** only with settings from IT.

The sidebar — 462px of chrome before the first chat

The wordmark keeps its own line. Sharing the band with the traffic lights saved 32px but buried the brand between two rows of controls; on its own line it introduces the app properly, and the compaction still lands because the row count does the work. In the band, a 16px channel separates the OS's traffic lights from our two controls, and the pair itself sits at 2px — one control group, not two loose buttons.

Twenty of those pixels come back, and the rail is better for it. shipped When the band dropped 52 → 44 the wordmark came up with it and landed 8px under the hairline with the first nav row directly beneath — three elements stacked at one rhythm, which reads as crowded rather than dense. The brand block now takes 16px above and 8px below (px-2 pt-4 pb-2), and the nav rows sit at 2px rather than flush: at zero the rounded washes touch, so a hover bleeds into its neighbours and the destinations read as one block of colour. 2px is the gap the menu recipe already uses between items, so the rail and the menus agree, and Recents takes the same gap — one rhythm down the whole column, or its two halves read as two different lists. Row height is untouched: --row-height-rail is still 32px, at a 34px pitch. Measured in the app: band 44px at y=0, wordmark 32px at y=60, first nav row at y=100.

The Recents well is gone — the app's only surface grounded on a color-mix of a border token, at a radius nothing else in the rail uses. The list now sits directly on the rail like every other list, glyphs at their real weight: a chat is a message square, a diverged session is a branch. Running sessions get a trailing status dot; the ring-and-glow stays in the chat.

Crew should reuse these through a **new collaboration control plane and per-user workers**, rather than exposing the existing single-user daemon to all SSH users. + +Three existing assumptions are incompatible with a shared server without additional controls: + +1. Session privacy is not user ownership. Current workspace authorization deliberately permits an agent to steer any local session it may read; unrelated sessions are permitted when the privacy tier allows them. Crew must separately enforce account, workspace, team, channel, and agent-owner permissions. +2. Current privacy protections have local opt-outs and locally writable state. Crew's server policy must be mandatory and cannot become weaker when a desktop preference changes. +3. The existing developer-shell sandbox restricts writes, not reads. A public-model worker that can read a user's entire home can obtain private data outside the chat API. Crew needs a read-isolated execution environment before permitting public workers to browse files on a private host. + +## Verified integration map + +Paths and line numbers refer to the baseline above. + +| Existing seam | Evidence | Reuse and limitation | +|---|---|---| +| Platform capabilities | `crates/biorouter/src/agents/extension.rs:44–159` | Platform registry includes workspace controls, chat recall, extension manager, skills, code execution and todos. `PlatformExtensionContext` has a session manager and weak extension-manager reference. A Crew tool surface belongs here when it needs the local admitted agent identity; a thin remote client can also be bundled as MCP. Neither placement should own the collaboration database. | +| Extension transports | `crates/biorouter/src/agents/extension.rs:272–396` | Supports stdio, bundled builtin, in-process platform, Streamable HTTP, frontend and inline Python. SSE remains only for config compatibility and is unsupported. Do not invent a separate extension stack for Crew. | +| MCP pooling | `crates/biorouter/src/agents/extension.rs:672–743`; `extension_manager.rs:191–232` | Pool key contains transport, working directory and environment fingerprint. It has no principal or Crew compartment. Platform and frontend transports are not pooled. Do not share credential-bearing MCP processes across users or compartments using the existing key. Prefer physically separate worker processes and stores. | +| Session persistence | `crates/biorouter/src/session/session_manager.rs:48–67,580–657,1747–1793,2020–2031` | SQLite `sessions.db`, message FTS, session manager and durable message identifiers are reusable patterns. `Session` has provider, directory, parent, classification and provenance fields, but no team, channel, SSH principal or agent owner. Crew needs its own schema, not columns overloaded into `name` or `extension_data`. | +| Privacy lattice | `crates/biorouter/src/privacy/mod.rs:245–374` | Provider capability defaults to public, composite providers take the least capable member, stored unknown classifications fail private, and classification ratchets upward. Provider binding is atomically checked in storage rather than trusting a check-then-write. Preserve these properties. | +| Tool capability | `crates/biorouter/src/privacy/capability.rs:40–85,169–251` | `CallCapability` samples provider tier and affiliation together, with a master-enforcement flag. Reuse the one-admission-decision principle, but Crew must carry authenticated principal, worker, channel grant, compartment and policy epoch too. | +| Workspace authorization | `crates/biorouter/src/privacy/visibility.rs:10–28,83–105,135–181` | READ and WRITE intentionally coincide and lineage is not a boundary. This is appropriate to the current single-user workspace but is insufficient for Crew's rule that only an owner prompts their agent. | +| HTTP authentication | `crates/biorouter-server/src/auth.rs:100–202,383–443` | Daemon `X-Secret-Key` authenticates access to a daemon; a separate `X-User-Action` digest supports selected human-action gates. Neither identifies multiple SSH accounts. Raw desktop user-action authority must never be given to workers or the shared broker. | +| Programmatic session reach | `crates/biorouter-server/src/routes/session_reach.rs:586–668,928–947` | Existing reach resolves a self-stated provider name against local provider metadata. Missing/unknown names are public. Crew must not treat a caller's provider-name header as an attested model identity or authorization to read a private channel. | +| Institutional affiliation | `crates/biorouter/src/privacy/affiliation.rs:1–26`; `privacy/mixing.rs:1–81,118–144` | There is already a third axis for institutional agreements, plus open/standard/strict mixing modes. `Local` is currently broadly permissive. Crew needs explicit approved destinations and data compartments; local hosting alone does not grant access to all teams or institutions. | +| Chat recall | `crates/biorouter/src/agents/chatrecall_extension.rs:315–395,526–567` | Tier and affiliation filters exist; search filtering is pushed into SQL before the limit. Crew retrieval must add membership and compartment filters before search ranking/counts/snippets, and repeat authorization at fetch time. Do not point general chat recall at every user's database. | +| Private-to-public crossing | `crates/biorouter/src/privacy/crossing.rs:1–40,47–79` | Current consent is first-crossing-per-session-pair, kept process-local. This does not meet a policy of reviewing each released payload. Crew should use a separate release object whose approval binds exact bytes, attachments, source labels, destination, policy version, expiry and approving principal. | +| Live session events | `crates/biorouter-server/src/routes/session_events.rs:237–382` | Existing SSE applies a reach gate, subscribes before a snapshot, provides bounded streams, and resynchronizes lagging observers from storage. Reuse event mapping and UI rendering; Crew additionally needs durable sequence cursors, idempotency and authorization revocation while subscribed. | +| Tool-result blobs | `crates/biorouter/src/session/message_blobs.rs:1–38,62–68` | This is large text-tool-result externalization into a side table, not an arbitrary file-sharing object store. Images remain inline. Crew needs upload/download state, binary storage, digest, ACL, quota and resumability. | +| Shell sandbox | `crates/biorouter-sandbox/src/shell_sandbox/mod.rs:49–94`; `shell_sandbox/linux.rs:180–257` | `SandboxPolicy` explicitly leaves the filesystem readable. Linux bubblewrap binds `/` read-only; `Full` means write confinement plus network denial, not read confidentiality. This cannot be claimed as a private/public data boundary. | +| Alternate sandbox backend | `crates/biorouter-sandbox/src/lib.rs:9–21,47–100` | Local backend has no process isolation; Docker backend offers mounted-workspace isolation, non-root execution, dropped capabilities, resource limits and no network by default. A container-compatible path is promising but requires real host verification and additional egress/provider design. | + +## ACP and MCP are different parts of the design + +ACP is an agent-client protocol: initialize, create/load an agent session, send a prompt, stream updates, request permission, cancel. It is a good adapter for invoking an owned agent and translating its progress into a channel timeline. It does not define teams, channel membership, durable message fan-out, attachment authorization, or the SSH account-to-principal binding. The official v1 transport page defines stdio and describes Streamable HTTP as a draft; custom bidirectional transports must preserve ACP lifecycle semantics. Use the version BioRouter actually supports and negotiate capabilities. [ACP overview](https://agentclientprotocol.com/protocol/v1/overview), [ACP transports](https://agentclientprotocol.com/protocol/v1/transports). + +MCP exposes tools, resources and prompts to a host, with the host controlling context and security policy. It is appropriate for `crew.search`, `crew.read`, `crew.post`, attachment references and channel operations made by a user's agent. It should not become the durable chat replication protocol. The 2026-07-28 MCP architecture is stateless and differs from older stateful releases; protocol upgrades must be a deliberate compatibility task, not a side effect of Crew. [Current MCP architecture](https://modelcontextprotocol.io/specification/2026-07-28/architecture). + +The checked lockfile contains `agent-client-protocol-schema 0.10.5` (`Cargo.lock:67–70`), `sacp 10.1.0` (`Cargo.lock:7222–7225`) and `rmcp 0.12.0` plus `0.14.0` (`Cargo.lock:6880–6905`). Lockfile versions alone are not a statement that every latest protocol feature is implemented. + +BioRouter's ACP implementation is not a ready multi-tenant server: + +- `BioRouterAcpAgent` stores a single `Arc` and provider plus an in-memory session map (`crates/biorouter-acp/src/server.rs:37–65`). Configured extensions are loaded onto that shared agent (`:345–379`). Use a separate owned worker instance per execution compartment rather than one instance for the whole team. +- Stdio ACP loads the launching user's configured tools (`:1144–1154`). WebSocket ACP intentionally suppresses configured tools and client-registered stdio MCP (`:1270–1291`). Preserve that distinction; do not enable arbitrary process-spawning MCP registration merely to make Crew work. +- WebSocket ACP uses bearer-token and origin checks (`:1209–1254,1293–1323`). These are not multi-user ownership or channel authorization. +- ACP maps text/images and text resources, but audio and non-text embedded resources are currently ignored (`:396–430`). Crew attachments must remain durable downloadable objects even when a particular agent cannot consume that type; report unsupported agent input explicitly. +- ACP emits message, thought, tool and permission updates (`:436–625`). Crew should publish intentional user-facing progress, commands, tool status and shareable results; do not indiscriminately fan out raw provider frames, credentials, hidden reasoning or every local-session message. +- The permission bridge explicitly says ACP alone cannot distinguish a human click from auto-allow (`:618–625`). Sensitive Crew approvals need an authenticated owner-side UI action and a broker-verified request-bound approval. + +## Proposed security model + +### Identities and ownership + +Use a stable server-assigned workspace ID, not a local SSH profile name. Profiles can point at the same remote deployment through different jumps, aliases and ports. Bind a remote principal to workspace ID plus the authenticated OS account's UID and an account-generation record; keep username as its stable visible label and nickname/avatar as mutable profile attributes. This avoids treating the same username on two hosts as one person and accounts for UID reuse. + +On a single Linux host, an administrator-managed broker can authenticate a bridge process's Unix account through a protected Unix domain socket and kernel peer credentials. The bridge itself runs after normal OpenSSH login as the user. This account proof is not human-control authority: broker application admission additionally requires an enrolled device/session credential or a scoped worker grant, as defined in the implementation plan. Bare UID access cannot enroll a human key or mint a human grant. Never accept `$USER`, a request `username`, `X-Caller-Provider`, the UI avatar, or a client-supplied UID as identity proof. Every hop must preserve normal host-key verification, institution MFA and approved SSH configuration. If the broker is on another host, local Unix peer credentials do not automatically prove the remote user's identity: an additional trusted relay or approved mutually authenticated deployment is needed. + +The broker owns collaboration records but does not execute shell commands as its service account. Each user's worker starts through that user's authenticated login and runs with that user's permitted OS identity, scheduler account and project allocation. A worker registration is bound to the kernel-authenticated principal plus an expiring, narrowly scoped agent grant. A client cannot register or prompt another user's agent by supplying their agent ID. + +Core permissions: + +| Operation | Required authority | +|---|---| +| Read channel/history/attachments | Active workspace identity, team membership, channel visibility, data compartment permission and applicable device/export policy | +| Post as a human | The authenticated human principal; account membership and channel write permission | +| Post as an agent | Worker grant bound to owner, agent, run, destination channel and accepted data labels | +| Prompt/steer/cancel an agent | Its owner; another member may request work conversationally but cannot trigger execution | +| Approve a sensitive tool action | Owner's authenticated interactive authority, bound to exact request/run/arguments; never a model-generated chat message | +| Create/invite/manage channel | Relevant team/channel permission; invitee must already have valid workspace identity | +| Remove a channel | Its original creator, as requested; admin quarantine and account-offboarding recovery are separate policy actions, never implicit ownership transfer | +| Change workspace privacy/provider policy | Institutional administrator/operator through a protected control plane | + +Directory discovery should expose only users registered with Crew and permitted to be discoverable, not enumerate all system accounts. Presence is ephemeral and must not authorize any operation. Team membership does not authorize reading unrelated Unix files; sharing a file is an explicit copy or granted object, not a pointer that causes the broker to read arbitrary paths as itself. + +### Mandatory policy intersection + +For every read, retrieval, publish, provider invocation and tool result, compute an intersection of authenticated principal permissions, team/channel membership, object ACL, worker/run scope, data labels, approved model endpoint and workspace policy. An allow at one layer never overrides a deny at another. Client preferences may make this more restrictive, not less. + +Treat channel visibility (`open-to-team`, `invite-only`) separately from data classification (`public-safe`, `restricted/PHI`). A team-open channel can still be restricted, and an invite-only channel can contain public-safe research. Add institution/project/dataset compartments and permitted processing destinations. An institutionally hosted provider is not a blanket clearance for another institution's dataset. Commercial hosting can be allowed for a particular restricted flow only when institution policy explicitly approves that exact deployment and use; do not infer approval from the provider brand or a boolean private flag. + +The broker must verify workers against protected endpoint configuration and policy; ordinary workers cannot self-assert that a model is private. Private execution needs deny-by-default network egress with an approved provider proxy or narrowly approved destinations. Apply the same boundary to embeddings, OCR, transcription, summarization, title generation, telemetry, previews, external-link fetches, plugins and tool subprocesses—not just the main LLM request. + +Public workers must not inherit private conversation state. Bind each run to owner, workspace, source channel, model policy and compartment. Reset or refuse incompatible model changes. A provider switch, membership change, policy change or revoked grant invalidates queued work and relevant long-lived streams. Check both at enqueue and immediately before execution/delivery. + +The entire execution environment must support the claimed confidentiality boundary. A shell command can bypass application retrieval rules by reading files directly. Public workers therefore need explicit readable mounts, hidden host home/cache/SSH sockets, restricted process inspection, no arbitrary credentials, and a broker channel restricted to the worker grant. Separate user-owned processes without read isolation do not establish this. If the host cannot provide it, restrict public-model execution to public-only workspaces and keep protected cluster-file tools unavailable. Every worker, including a private-model worker, also needs isolation from human-control keys, unscoped sessions and enrollment/approval authority. If that separate boundary is unavailable, support human chat only; an approved private provider does not authorize its agent to approve its own actions. + +The enforceable threat model must be stated: server-side controls protect against unauthorized peers, mistakes and compromised/scoped agents. An authorized human can still manually copy data they are entitled to read unless institutional endpoint controls also apply. Root administrators and host compromise are part of the trusted computing base, not solved by SSH encryption. + +### Context retrieval and information flow + +Default to the current channel's permitted conversation window and explicitly attached artifacts. Optional cross-channel retrieval can be convenient without sending every channel to every model: search only within the actor's approved channel set and data compartments, with filters applied before ranking, snippets, counts and pagination. Record which channel/message/file versions actually entered context. Cross-workspace retrieval is disabled by default and requires an explicit policy-compatible selection. + +Derived context inherits the union of source restrictions. A summary, embedding, generated filename, image thumbnail or copied artifact is not automatically public. Publishing derived output requires that every recipient and destination satisfies that union. Preserve source-ACL dependencies and apply them to every future reader, including later invitees, search/replay and cached context; channel membership growth cannot silently widen the audience of retained derived material. Reading two separately restricted channels can produce output that neither whole channel may receive; offer the run's owner a restricted result and explain the missing destination permission. + +Treat shared human and agent messages as untrusted task data. A colleague posting `@other-person-agent run ...` must not be interpreted as owner authorization. Only an authenticated owner action creates an invocation. Model-triggered slash commands still pass the same broker ACL, publication gate and request-bound approval rules. + +Private-to-public movement should create a new release artifact with exact proposed text/files, source provenance, destination and an expiry. Institutional policy decides whether such release is even available. Approval releases only that artifact; it does not declassify the source channel or grant standing permission for subsequent messages. No automatic cross-workspace mirroring, automatic public summaries, or generic first-crossing grants for protected work. + +### Storage and event boundaries + +Keep the authoritative Crew store broker-owned, with one writer and an append-only JSONL journal as the canonical record. This follows the user's preference for simple portable text storage and streaming over throughput. Attachments are ordinary opaque files; derived search and lookup indexes can be rebuilt. Crew should not require SQLite, PostgreSQL, Redis or a container runtime to provide human collaboration. The existing worker's personal BioRouter session database stays separate from the shared channel journal. + +Text files still need a transaction and recovery design. Use versioned records, monotonic sequence numbers, bounded frame lengths, record digests, a process lock, durable write/`fsync` ordering, and atomic manifest/checkpoint replacement on the same filesystem. A multi-event mutation must have one unambiguous commit boundary; replay ignores or quarantines incomplete trailing records and refuses corrupt committed history. Attachment finalization precedes the committed event referencing it, and orphan cleanup follows a recovery-safe grace period. Prefer one workspace journal initially to avoid pretending separate channel files give atomic cross-channel membership and invite changes. Segment and compact only with tested retention, audit and cursor semantics. Benchmark at expected team size before adding indexes or sharding. + +Use local durable server storage for the writer and its live journal. An NFS home is not made safe merely by using JSONL: locking, cache visibility, atomic replacement and durability must be verified for that filesystem and cluster topology. Do not place independently writing brokers on several login nodes against the same journal. An administrator-provisioned persistent service host and local durable volume are the preferred baseline; approved storage support is a deployment prerequisite when unavailable. + +Messages and events need immutable IDs, monotonically ordered per-channel positions, server timestamps, authorship, edit/tombstone events, idempotency keys, reply/thread relationships and ACL/policy revisions. Reconnect should resume from a durable authorized cursor. The broker commits before acknowledgement/fan-out; duplicates after network loss must not create duplicate messages or duplicate agent jobs. Keep heartbeat presence separate from the durable event log. + +Store attachments as opaque objects under broker-assigned IDs. Record hash, byte size, safe display filename, media type, uploader, channel ACL and inherited labels. Support arbitrary byte downloads with limits and resumable chunks; verify hashes and finalize atomically. Do not render active HTML/SVG or execute uploaded files by default. Previews, antivirus and indexing run inside the same boundary. Authorized downloads and local caching should be visible, policy-controlled actions, with local encrypted storage and revocation-aware cache behavior where required. + +Operational audit should record actor, action, object reference, decision, policy revision, approved release digest and run/provider identity, while minimizing raw payloads. A broker-owned append-only journal is useful but not tamper-proof against its administrator; stronger audit retention needs a separately controlled destination. Backup/restore, retention, deletion and legal hold are deployment requirements to be decided by the institution, not properties obtained from the SSH transport. + +## Implementation sequence and acceptance gates + +1. **Define protected domain types and pure authorization rules.** Introduce workspace/principal/team/channel/member/agent/run/attachment/context/release records. Separate visibility from classification. Test the full actor-operation-object matrix and no-existence-leak responses using synthetic fixtures. +2. **Build a minimal broker and SSH stdio bridge.** Prefer one portable Linux Rust binary with broker/bridge/worker subcommands and a line-framed JSON control protocol; binary attachments use bounded chunks with explicit encoding/length/digest. The broker uses kernel-bound identities and a protected single-writer JSONL journal. Test two distinct OS accounts, forged JSON identity, unauthorized channel reads, stream revocation, duplicate command IDs, disk-full/partial-write recovery and disconnect recovery. A same-account two-client smoke is transport evidence only. +3. **Human collaboration vertical slice.** Profiles, teams, invites, creator-owned channel deletion, text, file upload/download and current-channel presence. Validate multi-account permissions, filename/path traversal, symlink swap resistance, quota and interrupted upload recovery before agent execution. +4. **Owned agent vertical slice.** A per-owner/per-compartment worker wraps existing BioRouter agents or ACP. Wire command/status/result events to a Crew timeline and owner-only approvals. Assert another account cannot prompt, cancel, approve or use a guessed run/session identifier. Never give the broker a general-purpose shell. +5. **Mandatory privacy and worker isolation.** Enforce provider destination allowlists, inherited labels, compartment-filtered retrieval, public-worker readable mounts and egress. Use synthetic restricted markers and a fake public endpoint to prove zero leaked bytes across model requests, tools, previews, logs, titles and reconnect snapshots. Refuse protected execution if required OS enforcement is unavailable. +6. **Crew tools and desktop integration.** Add the sidebar tab, workspace selector and MCP/platform tools with explicit workspace/channel arguments where ambiguous. Reuse chat renderers and agent-event cards; keep shared messages separate from a personal session transcript. Preserve generated OpenAPI discipline for changed daemon APIs. +7. **HPC operation and production evaluation.** Separate persistent collaboration service from scheduler jobs. Test queued/running/completed/cancelled jobs, owner UID/account preservation, compute-node reconnect, scheduler limits, multi-hop and MFA paths, package installation, upgrades, backups, retention, restore and independent security review. PHI admission waits for the institution's approval of the concrete deployment. + +This investigation ran no application builds or unit suites and did not verify live sandbox enforcement on either SSH host. Those are explicit feasibility/acceptance tasks; source presence and test names are not substitutes for execution evidence. diff --git a/docs/research/biorouter-crew/aws-identity-smoke-report.md b/docs/research/biorouter-crew/aws-identity-smoke-report.md new file mode 100644 index 000000000..3fea2dbff --- /dev/null +++ b/docs/research/biorouter-crew/aws-identity-smoke-report.md @@ -0,0 +1,43 @@ +# AWS identity and SSH transport feasibility + +The synthetic smoke passed on 2026-09-22 UTC using one disposable Amazon Linux 2023 `t3.micro` in `us-west-2`.

[Revoke access](#revoke-access) and the grant states describe the source as of 2026-09-25 (`dc274655`), after the automatic revocation retry landed. +> **Audience:** People who use Crew from a terminal, and developers and testers of the Crew CLI. + +The native CLI and the desktop Crew panel call the same daemon services for connections, membership, transfers, policy and owned tasks, and the same daemon resolves the names both of them accept. Crew is BioRouter's shared workspace for a lab: a small broker process runs under one member's Unix account on a Linux server, and every member reaches it over their own SSH login. + +Shared profile IPC currently requires Unix: an authenticated, owner-protected Unix socket connects clients to `biorouterd`. Native Windows shared-daemon attachment is not implemented; there is no TCP fallback for the CLI. The remote Crew broker and bridge currently require Linux. A workspace host must start that broker before anyone connects. + +## Start the daemon and choose credential storage + +```bash +biorouter crew --help +biorouter crew daemon status +biorouter crew daemon start +biorouter crew credentials status +``` + +`daemon status` checks the discovered instance without asking for the human approval secret; it reports an error if no instance is available. Run `daemon start` only when the daemon is absent: it refuses an already running instance. Ordinary Crew commands require the approval secret and can start a missing daemon; add `--no-start` to require an existing instance. Credential commands require an existing daemon. + +The CLI and desktop must use the same BioRouter profile to share an instance. On Unix, the desktop normally discovers or starts this profile daemon and asks for its approval secret. Closing the desktop or exiting the CLI leaves the shared daemon running. Explicitly stop it with `biorouter crew daemon stop`; that affects every client attached to the instance. An explicit desktop shared-daemon opt-out or an external backend is a different deployment mode. + +In the desktop Crew view, select the same saved connection, sign in when SSH asks for a password or MFA, and pick a team and channel for messages and tasks. Keys and security manages the same keyring or vault backend the CLI uses. Desktop file pickers and CLI file paths both register selections with the daemon's transfer service; switching clients does not create a separate workspace or transfer engine. + +There are three separate credentials: + +| Credential | Purpose and input | +| --- | --- | +| Human approval secret | Authorizes human operations in this daemon. Choose and retain it separately when starting a new instance; supply the same secret when attaching. It must contain 32–4096 printable ASCII characters without spaces. It is not recovered from daemon discovery metadata or desktop settings. | +| Optional encrypted-vault passphrase | Unlocks this profile's Crew device credentials. It must differ from the approval secret; the vault accepts 1–1024 UTF-8 bytes. The OS keyring is the default credential backend. | +| SSH credentials and MFA responses | Enter only in the native SSH authentication terminal. They are not Crew messages, agent prompts, device codes, enrollment tokens or vault passphrases. | + +To use an encrypted vault, initialize it **before preparing identities or saving connections in a fresh Crew profile**. Existing keyring identities are not migrated by this command: + +```bash +biorouter crew credentials init +biorouter crew credentials lock +biorouter crew credentials unlock +``` + +The default secret prompts hide input. `--approval-key-stdin` explicitly reads exactly the first stdin line as the approval secret. For `credentials init` or `credentials unlock`, the second line supplies the distinct vault passphrase. With `send --input -`, `connections save -` or `connections join-invitation -`, the remaining stdin content is the message, the JSON descriptor or the pasted invitation. Supply such input through a trusted secret-input pipe; do not put secrets in command arguments, shell history, environment variables or connection JSON. Native `auth` still requires an interactive terminal, so use its normal hidden approval prompt. + +For privacy-sensitive actions, add `--expected-mode private` or `--expected-mode public`, for example `biorouter crew --connection lab --expected-mode private send methods --text 'Hello'`. The daemon refuses a mismatched saved mode instead of changing it. This optional expectation applies to `send`, `tasks start`, `grants grant`, and file upload, download and resume selection; omission preserves existing behavior. It does not change the connection's privacy setting or apply to file cleanup. + +## Install the remote executable before connecting + +Every connecting ordinary Unix account on the Linux SSH host needs its own executable at **`~/.local/bin/biorouter-crew`**. The daemon invokes that exact path for `bridge --stdio`; an executable only in `/usr/local/bin` or `/usr/bin`, or available only through `PATH`, does not satisfy this prerequisite. The account hosting the broker needs it too. + +Obtain and verify a `biorouter-crew` artifact qualified for the target Linux architecture and runtime.

An agent's remote work folder (`remote_root`) may never be, contain or sit inside `~/.local/bin`, `~/bin`, `~/.bashrc.d`, `~/.profile.d`, the folder holding the bridge executable, or the credential and Crew state folders: the bridge refuses remote file and command operations there (`invalid_scope`) and suggests a folder such as `~/crew-work/lab`. + +Use qualified local persistent storage and an institution-approved SSH route. Check [Linux artifact portability](linux-portability.md) and [institutional SSH requirements](institutional-ssh-compatibility.md) before deployment; version output alone does not qualify kernel, filesystem, confinement or institution policy.

The shared daemon looks each name up in your own view of the workspace (the same `POST /crew/resolve` the desktop uses), so it can only ever find things you could already see.

A display name never selects anyone, so a nickname that looks like someone else's cannot redirect a command. A username that differs only in letter case is refused with `Did you mean @bob?`, never corrected silently. +- **Nothing is guessed.** An unknown name prints one line saying so and lists nothing. An ambiguous name lists only candidates you can see and says how to narrow it (for a channel, name its team: `analysis-lab/general`). Either way the command sends nothing and exits with status 1. When several names are wrong, each gets its own line. +- **Person-targeted changes are checked twice.** `invites create`, `members add`, `remove-member`, `ownership offer` and `enroll revoke` send the `@username` you typed along with the ID it resolved to, and the broker refuses the change (`target_mismatch`) if that account is no longer the one you named. +- **Quote a `#`.** In bash, and in zsh with `interactivecomments`, an unquoted `#methods` starts a comment and the command loses its argument. Write `'#methods'` or leave the `#` out: `methods` works everywhere. `@bob` needs no quotes. +- **There is no current team.** A channel name that exists in two of your teams (every team has a `general`) is ambiguous until you qualify it. +- **An older daemon** answers names with `Restart the shared Biorouter daemon to use names; IDs still work.` Restart it, or pass IDs. + +Text output names people as `"Bob Lee" (@bob)`, or `@bob` alone when the display name is just the username, and channels as `#methods`; it hides machine IDs. + +### Scripting with IDs + +Scripts can keep passing IDs: UUID-shaped arguments never reach the resolver, so they work against any daemon, including one that predates names. To see IDs, add `--show-ids`, which appends them to text output, or use `--output-format json`, which always carries them. Where they come from: + +- A saved connection's ID is `id` in `connections list` and `connections show`. +- `teams create` returns `team.id` and `channel.id`; `channels create` returns `id`; `members --show-ids` lists principal IDs. +- `files upload` and `files download` return a transfer receipt with `id`, and a completed upload carries `blob_id`. Task starts return `run_id`. + +Files, transfers, tasks and chat sessions are never looked up by name: `files download` and `send --attachment` take a `blob_id`, `files status|watch|pause|resume|forget` a transfer ID, `tasks show|watch|cancel` a run ID, and `context`, `grants grant` and `grants revoke` a chat session ID. `enroll revoke` given an ID never asks for confirmation, so a script can use it. + +```bash +CONNECTION_ID='replace-with-saved-connection-id' +CHANNEL_ID='replace-with-channel-id' +biorouter crew --connection "$CONNECTION_ID" --output-format json history "$CHANNEL_ID" --latest --limit 50 +``` + +## Join a workspace + +The host starts the broker once and invites each person by their username on the server. A person joins by pasting the host's invitation, signing in, and sending the host a 16-character code their own computer computed; the host types that code to let them in. Nobody copies a key, a socket path or a numeric user ID. + +> **Note.** Letting someone in with a code needs a broker built with the `join-by-name` feature; it advertises `join_by_name_v1`. The feature is on by default since 2026-09-25, after its adversarial review and live multi-account runs passed (naming decision D17), so a broker built without feature flags has it. Against a broker built with `--no-default-features`, or one from before the feature, `crew join` says the server can't let people join with a code yet, `enroll invite @bob` is refused, and the host uses the [older enrollment token](#enroll-with-a-token-older-versions) instead. Saving a connection from an invitation works with every broker. + +### Host a workspace + +Prepare this computer's hosting identity, then start the broker on the server as your own account with the public key it printed. `--name` names the workspace: 1–40 lowercase letters, digits and dashes. With `--name`, the state directory defaults to `~/.local/share/biorouter-crew/`; `--state-dir PATH` still sets it explicitly. + +```bash +biorouter crew connections prepare +# Note preparation_id and public_key from the output. + +# On the server, as the hosting account: +"$HOME/.local/bin/biorouter-crew" start --name lab --bootstrap-key 'PUBLIC_KEY_HEX' +``` + +`start` waits for the broker to answer and prints JSON whose `invitation` field is a `brcrew1:` line. Save your own connection from it, naming how you reach the server (an alias from your SSH settings, or `alice@hpc.ucsf.edu`) and the institution for a Private workspace. Then sign in, claim the workspace with the key you prepared, and confirm its institution label: + +```bash +biorouter crew connections join-invitation ./lab-start.txt \ + --preparation-id 'PREPARATION_ID' --ssh-target hpc --institution ucsf +biorouter crew --connection lab auth +biorouter crew --connection lab workspace bootstrap +biorouter crew --connection lab privacy set-workspace private --institution ucsf +``` + +The institution label is permanent. Confirm it after `workspace bootstrap` and before any agent task or grant. The [rootless setup checklist](protocol-contract.md#rootless-setup-checklist) lists the broker's lifecycle commands (`status`, `stop`) and what `start` checks. + +### Invite someone and let them in (host) + +```bash +biorouter crew --connection lab enroll invite @bob +``` + +The host's broker checks that `bob` is an account on the server, looking up that one name and never listing accounts. The server's own accounts can't be invited: `root`, any account below the server's `UID_MIN` (from `/etc/login.defs`, 1000 when it doesn't say), `nobody`, and any account whose login shell is `nologin` or `false` are refused with `@root is a system account on this server and can't join a workspace.` The command prints `Invited @bob · "Bob Lee" (name on the server account).` and then the invitation message to send Bob: + +```text +Join lab on Crew. +In Biorouter, open Crew, choose Join a workspace, and paste this whole message. +brcrew1:eyJ2IjoxLCJ3b3Jrc3BhY2VfaWQiOiIuLi4ifQ +``` + +`connections invitation --for @bob` prints the message again. An invitation carries the workspace key, the server's address, and the workspace's privacy mode and institution; it holds no secret, and forwarding it to the wrong person gains them nothing without an account you invited and your approval of their code. + +When Bob sends you his code, check who is waiting and let him in. Type the code as he sent it; case, spaces and dashes don't matter: + +```bash +biorouter crew --connection lab enroll pending +biorouter crew --connection lab enroll approve @bob 7QK2-M9XA-3JTP-WZ4D +``` + +- **Saving a code is not letting someone in yet.** `enroll approve` answers `Code saved. @bob joins when their computer confirms the same code.` The broker compares the code only when Bob's computer claims it, so a code you mistyped is caught then, not here. +- **Approve only a code the person sent you themselves.** If `enroll pending` says `A computer trying to join as @bob showed a different code. Check the code @bob sent you; if you typed it wrong, run enroll approve again with --replace. Don't approve a code you didn't get from @bob.`, either you typed Bob's code wrong or something other than Bob's computer tried to join. Compare with the code Bob sent you; never approve one you did not get from him. +- `--replace` replaces a code you already entered. Running `enroll approve` again with a different code and no `--replace` is refused with `You already entered a code for @bob.` and, on the next line, the command that replaces it. `enroll cancel @bob` withdraws the invitation. An invitation expires after 24 hours; inviting again replaces it, and Bob's screen then shows a new status. +- `enroll invite @bob --add-device` invites an existing member to add another computer. + +### Join (joiner) + +Save the host's message to a file, check what it says, save the connection, sign in and join: + +```bash +biorouter crew connections join-invitation ./lab-invitation.txt --preview +biorouter crew connections join-invitation ./lab-invitation.txt +biorouter crew --connection lab auth +biorouter crew --connection lab join +``` + +- **The preview is the privacy decision.** It names the workspace, the host and the server, shows the fingerprint and the workspace's privacy (`Workspace privacy: Private · ucsf`), and says how this computer will treat it (`You'll join as Private · ucsf.`). If you choose another institution than the workspace's, it says so (`lab uses ucsf; you chose foreign-lab.`). One computer can't use one server for two institutions, so when another saved connection already reaches the same server under a different institution, the preview warns before you save: `You already use this server for foreign-lab (foreign-synthetic). lab uses ucsf; one computer can't mix institutions on the same server.` Connecting such a connection is refused in the same words. Without `--yes` the command asks `Save this connection? [y/N]` before saving anything. `--mode` and `--institution` change your own choice; `--username` sets your username on the server (default: the one the host invited); `--name` names the connection on this computer (default: the workspace's name). `--ssh-target`, `--port`, `--identity-file` and `--proxy-jump` (empty for none) override the server hints. +- **Pasting instead of a file:** `connections join-invitation -` reads the message from stdin (end it with Ctrl-D). Because there is then no terminal to ask in, it saves only with `--yes`; check it with `--preview` first. +- **`crew join` prints your code and waits:** `"Alice Chen" (@alice) invited you to lab.` and `Send Alice this code: 7QK2-M9XA-3JTP-WZ4D`. Your computer computes the code from its own device key and the workspace key in the invitation; nothing the server sends can change it. When Alice approves it, `join` finishes with `You're in lab.` Ctrl-C stops waiting and leaves the invitation open; run `join` again to continue. `--no-wait` prints the current state and returns, for scripts. +- If Alice typed a different code, `join` says `The code @alice entered doesn't match this computer. Send it again: …` with your code. It never prints `Joining lab…` for a code that doesn't match: once Alice saves a code, `join` claims first and then reports what the claim found, and with `--no-wait` it says `Alice saved a code for you, but this computer hasn't joined lab yet. Run biorouter crew join to finish.` when the claim hasn't completed. If you were not invited, it says so and waits for an invitation; an expired invitation ends the command with status 1 and asks you to request a new one. Sign in with `auth` before the first `join`. + +An older shared daemon answers these commands with `Restart the shared Biorouter daemon to invite or join with an invitation.` + +### Enroll with a token (older versions) + +The enrollment token is the path for a host or joiner on an older version of Biorouter, and for a broker without `join_by_name_v1`. It remains until two releases after joining by invitation ships enabled. Its commands are hidden from `--help` and print a deprecation notice. + +1. The joiner saves a connection (from the host's invitation, or from a [descriptor](#save-a-connection-from-a-descriptor)) and sends the host its device public key, `public_key` in `connections show`. +2. The host finds the joiner's numeric user ID (`id -u bob` on the server) and issues a token: + `biorouter crew --connection lab enroll invite --uid 12345 --public-key 'DEVICE_PUBLIC_KEY_HEX'`. For another device of an existing member, add `--existing-principal PRINCIPAL_ID` (from `members --show-ids`). +3. The host delivers the token through an approved private channel, and the joiner accepts it at the hidden prompt: `biorouter crew --connection lab enroll accept`. `--token-stdin` reads it from stdin (the line after the approval secret when `--approval-key-stdin` is also given); `--token-fd FD` reads it from an explicit file descriptor. + +The authenticated remote account and the enrolled key establish identity in both paths; display names do not change that authority. + +### Save a connection from a descriptor + +Use a JSON descriptor to script a save, or when the host gave you the workspace details rather than an invitation. `connections prepare` and `enroll prepare` are aliases for the same operation: + +```bash +biorouter crew connections prepare +biorouter crew connections save ./crew-connection.json +biorouter crew connections list +``` + +Build `crew-connection.json` from verified workspace information supplied by its host. It is a JSON object with these fields; it contains no device private key or password: + +| Field | Value | +| --- | --- | +| `preparation_id` | The ID from `connections prepare`, to use the device public key already shared for enrollment. Use only when saving a new connection. | +| `name` | A display name. | +| `ssh_target` | Your SSH host alias or `user@host`, using your own remote account. | +| `socket_path` | The broker's verified absolute remote socket path. | +| `owner_uid` | Numeric Unix UID of the remote broker owner; this is not necessarily your own SSH UID. | +| `workspace_id` | The host's verified workspace UUID. | +| `workspace_public_key` | The broker's verified 32-byte public key encoded as 64 hexadecimal characters. This is different from your prepared device public key. | +| `mode` | `private` or `public`; omission defaults to `private`. | +| `institution_id` | Required for private saves, optional for public. Canonical 1–64 lowercase ASCII letters, digits, underscores or hyphens, starting with a letter or digit (for example `ucsf`). Omitting `mode` still requires this field because the default is private. | + +Optional fields are `port` (number), `identity_file` (absolute local path), `proxy_jump` (SSH jump route), `remote_root` (remote work directory), `remote_execution` (boolean, default `false`) and `cluster_connection_id` (existing cluster connection ID). Unknown fields are rejected. `connections show` includes read-only state, so its entire output is not a valid save or update descriptor. For updates, omit `preparation_id` and supply the complete editable descriptor. + +### Sign in and manage saved connections + +```bash +biorouter crew --connection lab connections show +biorouter crew --connection lab auth +``` + +`auth` opens the daemon-owned native SSH terminal for host authentication, passwords and MFA, including admitted `ProxyJump` hops. Wait for the daemon's verified authentication result: it connects the Crew bridge automatically. `connect` can open a bridge using an already available authenticated connection; `disconnect` closes the selected connection. Follow the [SSH hop policy](ssh-hop-policy.md) for known-hosts setup, supported jump syntax and configuration restrictions. SSH transport alone is not a HIPAA compliance determination. + +The daemon keeps a connected bridge alive while it is idle and dials it again without a prompt when it drops. After a network failure it tries again after 20 s, 60 s and 180 s, then every 5 minutes for up to an hour, so a connection comes back by itself when the network does. It never dials again after `disconnect`, while a sign-in is pending, or after a failure only a person can fix. If the workspace no longer knows this computer (its host ran `enroll revoke`), the connection stops for good: `connections list` shows it disconnected with `This computer is no longer a member of lab.`, and JSON output carries `"last_error_code": "crew_membership_ended"` beside `last_error`. Nothing reconnects it by itself; `connect` still may, and checks from scratch. + +Connection selection is automatic only when exactly one connection is saved. Otherwise pass `--connection` with the connection's name, SSH target or ID. To replace settings or remove the local saved connection: + +```bash +biorouter crew --connection lab connections update ./crew-connection.json +biorouter crew --connection lab disconnect +biorouter crew --connection lab connections remove +``` + +## Create teams and channels, and invite members + +```bash +biorouter crew --connection lab profile set 'Alex Kim' --avatar 'AK' +biorouter crew --connection lab teams create 'Analysis Lab' +biorouter crew --connection lab teams list +biorouter crew --connection lab channels create methods --team analysis-lab +biorouter crew --connection lab channels list --team analysis-lab +``` + +Team creation also creates its `general` channel, classified `restricted` in a private workspace or `public_safe` in a public workspace. Explicit `channels create` defaults to `restricted`; `--classification public-safe` requests that separate classification. Avatars accept short text such as initials or emoji. `profile set` sets the display name people see beside your `@username`; it confers no authority. + +Names are unique, and the broker enforces it: + +- A team name is unique in the workspace. Letter case, spacing, dashes, dots, invisible characters and look-alike letters from other scripts don't make a second name: `Analysis Lab`, `analysis-lab` and `ANALYSIS_LAB` are the same team. +- A channel name is unique in its team, archived channels included, and `general` is reserved. Channel names are lowercase with dashes, so `channels create 'Data Analysis'` saves `#data-analysis` and says so. +- A refused name reads the same whether or not you can see the team or channel that holds it. After ten such refusals in ten minutes the broker answers `Too many name attempts. Try again later.` Everyone in a team can tell whether a name is taken, so keep identifiers out of names. + +Rename with `teams rename analysis-lab 'Analysis Group'` (the team's creator), `channels rename analysis-lab/methods protocols` (the channel's owner) or `workspace rename NEW` (the host). A rename keeps the object's ID, so history, invitations and grants are unaffected. + +To invite a member of the workspace to a team you created or a channel you own: + +```bash +biorouter crew --connection lab invites create @bob --team analysis-lab +biorouter crew --connection lab invites create @bob --channel analysis-lab/methods + +# Bob: +biorouter crew --connection lab invites list +biorouter crew --connection lab invites accept analysis-lab +``` + +A channel invitation's recipient must already belong to the team. `invites accept` needs no argument when you have one pending invitation; otherwise name the team or `team/channel` it is for. Users can belong to multiple teams. + +On a broker that advertises `direct_add_v1`, a team's owner (or the workspace host) can add a member of the workspace straight into the team, its `#general` and any channels of it they own, with nothing for the member to accept: they agreed to take part when they joined the workspace. + +```bash +biorouter crew --connection lab members add @bob --team analysis-lab --channel '#methods' +biorouter crew --connection lab members add @bob --channel analysis-lab/methods +``` + +- The first form answers `Added. @bob can now see #general and #methods.` Without `--team`, each `--channel` adds Bob to a channel you own in a team he already belongs to. +- Only a person's own device can do this, never an agent's grant. The broker checks that you own the team (or each channel) or host the workspace, that `@bob` is still the member you named on this server, and that every channel is in that team; one wrong channel refuses the whole add. Adding someone who is already there is a success that changes nothing, and `--request-id` retries are safe. +- An older broker answers `This workspace's server can't add people directly yet.`; use `invites create` there. + +The current channel owner can run `remove-member analysis-lab/methods @bob` (add `--former` for someone who has already left the workspace) or `channels archive analysis-lab/methods`. Ownership transfers require `ownership offer methods @carol` followed by Carol's `ownership accept methods`. **Acceptance removes the previous owner from that channel.** + +The host can remove a person from the whole workspace with `enroll revoke @bob`. It revokes their enrollment, devices and agent grants, which is different from removing someone from one channel, so it asks you to type `@bob` again. Where there is no terminal to ask in, pass `--confirm @bob`; `enroll revoke PRINCIPAL_ID` never asks. + +These commands name the person the way every list does: `"Bob Lee" (@bob)` when Bob set a display name, and `@crew_frank` alone when the display name is the username, as in `Removed @crew_frank from #methods.` + +## Read, post and follow channel messages + +```bash +biorouter crew --connection lab history methods --latest --limit 50 +biorouter crew --connection lab send methods --text 'The analysis is ready.' +biorouter crew --connection lab send '#methods' --input ./update.txt +biorouter crew --connection lab search analysis-lab/methods 'analysis' --limit 50 +biorouter crew --connection lab watch methods +``` + +`send` prints `Posted to #methods.` History accepts `--before CURSOR` or `--after CURSOR`, and search accepts `--after CURSOR`. Use the opaque cursors returned by Crew without modifying them. `watch` starts from the oldest available messages unless given `--after CURSOR`. The daemon polls, checks channel access and streams authorized pages; the CLI renders that shared stream. Ctrl-C detaches the watcher. `channels mark-read methods` marks the channel read up to its newest message; add a cursor to stop earlier. + +Use `--output-format json` for structured single responses. Watch commands emit one JSON value per line with either `json` or `stream-json`. Text output escapes terminal control characters. Content in messages, files and agent output remains untrusted input. + +When the daemon ends a watch, text output says why in one sentence, for example `Stopped watching #methods: You no longer have access to this channel.`, or `Stopped watching #methods: This computer isn't a member of this workspace.` when the workspace no longer knows this computer (the words `history` uses for the same refusal). The observer's code (`channel_access_changed`, `scope_changed`, …) is in the JSON error frame, never in the text. + +## Transfer attachments or share remote references + +```bash +biorouter crew --connection lab --request-id upload-analysis-001 files upload methods ./analysis.txt + +TRANSFER_ID='replace-with-transfer-id' +biorouter crew --connection lab files status "$TRANSFER_ID" +biorouter crew --connection lab files watch "$TRANSFER_ID" + +# Use blob_id from the completed upload receipt: +BLOB_ID='replace-with-blob-id' +biorouter crew --connection lab send methods --attachment "$BLOB_ID" +biorouter crew --connection lab files download "$BLOB_ID" --output ./downloaded-analysis.txt +``` + +Uploads and downloads return a transfer receipt before completion; add `--show-ids` or `--output-format json` to see its transfer ID and, once an upload completes, its `blob_id`. Uploading does not automatically post a message; publish the completed `blob_id` with `send --attachment`. Repeat `--attachment` to attach multiple blobs. Add `--overwrite` to download only when you authorize replacing the selected destination. Images and other file types use the same attachment transfer service. + +Overwrite approval applies to the file selected at registration. If that file is replaced or changes during the download, publication is refused; a previously absent target cannot be silently replaced. Reselect the destination to approve a changed target when the receipt permits resume. If publication is unconfirmed, inspect the destination first; the daemon will not automatically repeat it. + +Choose an existing download destination directory owned by your user and not writable by group or others. The service refuses symlink path components and unsafe destination directories; choose a suitable directory rather than weakening its checks. + +`files pending` lists daemon transfer receipts for the selected connection. `files pause TRANSFER_ID` requests a pause; wait until the receipt is inactive before resuming or forgetting it. `files resume TRANSFER_ID PATH` reapproves the upload source or original download destination; retain `--overwrite` when that replacement permission is needed. Ctrl-C on `files watch` leaves the transfer running. + +For an incomplete download whose receipt has a `destination_identity`, use `files forget TRANSFER_ID --file ORIGINAL_DESTINATION`. The daemon verifies that selection and removes only its owned partial download before forgetting the receipt; it does not authorize overwriting a published file. For an upload, a completed download or an incomplete download without a destination binding, use `files forget TRANSFER_ID` without `--file`. + +A path reference is separate from a transferred attachment: + +```bash +biorouter crew --connection lab files reference methods '/project/analysis/results' --label 'Remote results' +biorouter crew --connection lab files show-reference REFERENCE_ID +biorouter crew --connection lab send methods --reference REFERENCE_ID +``` + +Creating a reference does not upload, download or validate that remote path's contents. + +## Run your own agent or grant an existing conversation access + +Choose an already configured provider and model allowed by the workspace and your personal privacy mode: + +```bash +PROVIDER_NAME='replace-with-configured-provider' +MODEL_NAME='replace-with-approved-model' +biorouter crew --connection lab --request-id analysis-task-001 tasks start methods \ + --input ./task-prompt.txt --provider "$PROVIDER_NAME" --model "$MODEL_NAME" --allow-posting +biorouter crew --connection lab tasks list + +RUN_ID='replace-with-run-id' +biorouter crew --connection lab tasks show "$RUN_ID" +biorouter crew --connection lab tasks watch "$RUN_ID" +biorouter crew --connection lab tasks cancel "$RUN_ID" +``` + +Before tasks or grants, use `privacy show` to inspect `connection_policy_epoch` and `workspace.policy_epoch`. Optional `--expected-policy-epoch` and `--expected-workspace-policy-epoch` bind the observed epochs only for task starts and grants, for example: + +```bash +biorouter crew --connection lab --expected-policy-epoch CONNECTION_EPOCH \ + --expected-workspace-policy-epoch WORKSPACE_EPOCH tasks start methods \ + --input ./task-prompt.txt --provider "$PROVIDER_NAME" --model "$MODEL_NAME" --allow-posting +``` + +Replace the epoch placeholders with the observed integers. Do not reuse stale values after policy changes. These flags do not apply to sends, transfers or cleanup. + +A private model that the workspace's institution has not approved is refused before the task starts, in the desktop's words: `gpt-5.5 is approved for ucsf. foreign-lab uses stanford. Choose a model approved for it, or a local model.` (`--output-format json` keeps the daemon's code, `crew_request_refused`.) + +A task that reads a file shared in the channel ends its posted result with a line the daemon adds from what the task actually read, for example ``Source: `gina-assay.csv`, shared by Gina Rossi (@crew_gina).`` (several files: `Sources: …`, with `and N more files` past 32). The file name is shown as code, so a name shaped like a link or like the line's own notes stays a name. When two shared files have the same name the agent uses the most recently shared one unless the task names a specific copy; the agent is given the channel's recent files by name, with the newest copy marked, before it reads any. The line tells same-named copies apart: the newest by when it was shared, in the daemon's local time with its offset (``shared by Gina Rossi (@crew_gina) at 2:20 AM UTC-7``, with the day in front when it was not shared the day the result was posted), because a posted line is read long after "newest" stopped being true; an earlier one as `earlier copy`. When the task read only an earlier copy it adds ``A newer copy of `gina-assay.csv` was shared and was not read.`` Two copies shared in the same second are told apart by the order the workspace lists them in. A task that read no shared file ends with `No shared file was read for this result.` instead, so every posted result ends in the daemon's line and a "Source:" line the agent wrote itself is never the last thing in it. Nothing in the agent's reply is removed; a footnote definition in it is shown where it was written, because the channel would otherwise draw it below the daemon's line. + +Task starts currently require explicit `--allow-posting` for the destination channel. Repeat `--context-channel analysis-lab/raw-data` to request additional source channels; membership and privacy policy still apply. `tasks list --show-ids` shows run IDs. `tasks watch` follows task status, while channel history contains published activity. Ctrl-C detaches a watcher; cancellation requires `tasks cancel`. + +Agents receive task-specific grants and cannot use another user's identity to start or control that user's tasks. Remote file access requires an admitted `remote_root`; remote execution additionally requires `remote_execution: true` in the connection descriptor and an allowed private provider. Agent file paths are relative to that remote work directory. Public-provider grants do not enable these remote file or execution capabilities. + +For an existing conversation, open it in the shared daemon and let its current turn finish before granting access. Only a chat saved on this device can be granted access: + +```bash +SESSION_ID='replace-with-conversation-session-id' +biorouter crew --connection lab --expected-policy-epoch CONNECTION_EPOCH \ + --expected-workspace-policy-epoch WORKSPACE_EPOCH grants grant "$SESSION_ID" methods +biorouter crew --connection lab grants list +biorouter crew --connection lab context "$SESSION_ID" +biorouter crew --connection lab grants revoke "$SESSION_ID" +``` + +`grants grant` also accepts repeated `--context-channel`. The daemon validates the conversation's actual provider and origin; a session ID alone does not authorize access. `grants list` shows each grant's kind (a chat, or one of your tasks), the chat's name and when it expires. `context` returns the authorized context manifest. + +A grant belongs to the chat it was made for. A later chat that happens to reuse the same session ID does not inherit it. Deleting a granted chat does not revoke its run: the grant stays in `grants list`, still restricting, until you revoke it. + +### Revoke access + +`grants revoke SESSION_ID` stops a chat, or one of your tasks, from using Crew. It succeeds only when the workspace confirms it: + +| Outcome | What the command prints | Exit status | +| --- | --- | --- | +| Confirmed (HTTP 200) | `Access revoked. Chat SESSION_ID can't use Crew until you grant access again, or start a new chat.` For a task session, also `Its task was stopped.` or its status | 0 | +| Stopped here, not confirmed (503 `crew_revocation_unconfirmed`) | `Stopped on this device. The workspace hasn't confirmed the revocation yet; Biorouter confirms it with the workspace by itself when the connection is back. biorouter crew grants list shows when it has.` | 1 | +| Refused | The daemon's reason, for example 404 `crew_grant_not_found`, 409 `crew_grant_other_connection` (the grant belongs to another saved connection; pass that one with `--connection`), 409 `crew_grant_replaced` (a new grant is live), 500 `crew_revocation_not_saved` or 403 `crew_user_action_required` | 1 | + +After the 503 the grant is already expired and saved on this device, so this computer's chat can no longer use Crew, but the workspace has not yet confirmed that the run is revoked. The daemon asks the workspace again by itself: at every connect, whether a person's `connect`, a keepalive re-dial or a request that re-dials, and, while connected, at growing intervals until the workspace confirms. No second command is needed, though running `grants revoke` again asks at once. The daemon keeps asking even if the chat is granted access again in the meantime; `grants list` then shows the earlier run under its own heading. `grants list` shows the state: `Stopped on this device; the workspace hasn't confirmed yet` until then, and `Revoked` afterwards. With `--output-format json`, each grant carries `revocation` (`unconfirmed`, `confirmed` or `ended_by_workspace`) and `remote_revocation_confirmed`. With `--output-format json`, every failure prints `{"error": …, "request_id": …, "code": …}`, where `code` is the daemon's code, such as `crew_revocation_unconfirmed`. + +A revoked chat stays restricted for good: its next Crew request is refused with `This chat's Crew access was removed. Start a new chat, or grant access again from Crew.` Revocation invalidates the grant; it is not proof that every already-started remote process has terminated. + +A grant can also end at the workspace after access was granted: when the workspace's policy epoch moves (a policy change, or any membership change), when the run's context becomes protected, or when its institution changes. The next Crew request is then refused with `Crew settings changed since access was granted. Grant access again from Crew.`, the grant is stopped on this device, and `grants list` shows `Ended: Crew settings changed` (`revocation: ended_by_workspace`). + +## Use a terminal conversation through the shared daemon + +**Bounded runtime qualification:** `5455ebf9` passes the full repository gate, native/Linux builds, deterministic Crew tool use, zero-dispatch revocation and an installed Qwen3:8b history/context/post workflow.

Native continuation recovery below is committed in `532c3b7d`, independently reviewed and covered by 11 shared-conversation and 16 daemon-client tests. The full repository gate, native and Linux non-test builds, and actual terminal leave/abandon/takeover recovery also pass at that checkpoint. Recovery is unavailable in the older `5455ebf9` pair. The [history mapping](evidence/source-only-history-20260922.md) preserves original evidence scopes; these examples are not a full parity claim. + +Create a daemon conversation without sending a model prompt, specifying both provider and model after the `session` subcommand: + +```bash +biorouter session --shared-daemon --no-start --create-only \ + --provider "$PROVIDER_NAME" --model "$MODEL_NAME" + +# Copy the exact daemon session ID returned above. +SESSION_ID='replace-with-returned-daemon-session-id' +biorouter crew --connection lab --expected-mode private \ + grants grant "$SESSION_ID" methods + +# Interactive continuation of that exact daemon conversation: +biorouter session --shared-daemon --no-start --resume --session-id "$SESSION_ID" + +# Alternatively, send one prompt to the same daemon conversation: +biorouter run --shared-daemon --no-start --resume --session-id "$SESSION_ID" \ + --text 'Summarize the Crew context that I have authorized for this conversation.' +``` + +Use the same BioRouter profile throughout, choose an allowed configured provider and model, and finish any active turn before granting access. Creation alone does not grant Crew access. Resume requires the exact session ID; it does not search local sessions. `--no-start` requires an existing daemon. Human approval uses the hidden prompt, or explicit `--approval-key-stdin`; keep that secret out of model prompts and arguments. + +The shared adapter uses daemon agent, reply and session services before constructing any local Agent or project bridge. Without `--shared-daemon`, ordinary `run` and `session` remain standalone local conversations; a daemon-issued Crew grant does not supply their process-local manager with the daemon's live SSH connection. A `--no-session` run gets its own session ID namespace, so it can never match a saved chat's grant. Unsupported local-only flags are refused in shared mode. The stream authenticates daemon identity before proof, uses bounded parsing and never automatically resubmits a turn after a transport error. + +Ordinary elicitation questions are answered directly through the Proven-only daemon route for that exact session; a desktop redirect is not required. Unsupported approval types receive an explicit refusal. Durable answer and history persistence is implemented and independently reviewed, but the approval, stream and cancellation acceptance matrix remains pending. An unknown question returns a typed no-write refusal; an answer recorded after its waiter ended reports `recorded_not_delivered`, and a persistence failure is distinct. The CLI treats only typed `unknown` as a no-op and never automatically resubmits an answer. + +If the exact session has a pending Stop-and-Send continuation, interactive resume +offers `takeover`, `abandon`, or `leave`. Takeover revokes the previous client's +continuation claim; abandonment discards the claim. Neither recovers another +client's unsent draft. Noninteractive commands leave pending claims unchanged. +A settling or changed generation requires another explicit inspection. The next +deliberately submitted turn uses the acquired lease; leaving before submission +releases only that known unused lease. An uncertain submission is never +automatically replayed or abandoned. These choices use the daemon's existing +human-approval and exact-generation checks. + +## Privacy, retries and recovery + +```bash +biorouter crew --connection lab privacy show +biorouter crew --connection lab privacy set-personal private +# Workspace host only: +biorouter crew --connection lab privacy set-workspace private +``` + +The accepted mode values are `private` and `public`. Workspace policy, personal mode, channel classification, provider policy and grants jointly restrict operations. A public setting or a `public-safe` channel does not override another restriction or automatically declassify private content. Connection and policy changes invalidate relevant grants and can require reconnection and renewed authorization. Each connection remains a separate workspace scope; cross-channel context is explicitly granted. + +For retryable broker mutations, task starts and transfer starts, retain the same `--request-id` and the same operation after an uncertain response. The ID must be 1–128 ASCII letters, digits, underscores or hyphens. Without an explicit ID the CLI generates one. When a mutation was sent and its outcome is unknown (no answer, or a server error), the error ends with a retry hint naming that ID; JSON output always carries `request_id`. + +A refusal from the workspace is printed as a sentence, never with the broker's code in front of it: `Only the team's owner or the workspace host can add people to it.`, not `forbidden: Only the team's owner…`, and `This computer isn't a member of this workspace.` for a device the workspace no longer knows. The code stays in JSON output as `broker_code`, beside the daemon's `code`, for scripts and for support. A different intended operation needs a different ID. This is not a blanket transaction mechanism for every command. + +Transfer retries reapprove the selected local file and compare the saved operation and file identity. An exact accepted replay returns the existing receipt without launching a second transfer; changed selection, content identity, scope or overwrite authority can be refused. Resume an interrupted transfer using `files resume`, rather than expecting a start replay to resume it. + +For recovery, inspect `daemon status`; if the daemon is absent, run `daemon start` first. Unlock an encrypted vault if used, authenticate the connection, then inspect `files pending`, `tasks list` and `grants list`. Do not assume tasks or transfers automatically resumed after a restart. If a task reports interrupted setup, an unknown durable outcome or unconfirmed cancellation, inspect its conversation or channel and retry cancellation or revoke the grant as indicated before deliberately starting another task. A successful local cancellation request alone does not confirm remote process termination. + +If daemon identity verification, approval-secret verification, workspace key verification or SSH policy preflight fails, resolve that reported mismatch before reconnecting. Do not replace trusted descriptors, keys or runtime files merely to suppress the refusal. An existing daemon with no human approval proof must be explicitly stopped and relaunched through a trusted launcher. + +Implementation references: [CLI arguments](../../../crates/biorouter-cli/src/commands/crew/args.rs), [command routing](../../../crates/biorouter-cli/src/commands/crew/mod.rs), [native daemon client](../../../crates/biorouter-cli/src/daemon_client.rs), [name resolver](../../../crates/biorouter-server/src/routes/crew/names.rs), [invitation and join routes](../../../crates/biorouter-server/src/routes/crew_authentication.rs), [connection schema](../../../crates/biorouter/src/crew/mod.rs), [profile and grant routes](../../../crates/biorouter-server/src/routes/crew_profile.rs), [desktop daemon attachment](../../../ui/desktop/src/biorouterd.ts). + +### Synthetic development QA input (bounded launch qualification) + +The Electron development shell has a new `--dev-approval-key-stdin` path for explicitly authorized synthetic QA input. It requires an unpackaged app, validated development profile, test driver and shared daemon. Input is bounded, single-use, read through EOF and strictly validated; failures are sanitized. Three automatic no-prompt launches, 46 focused tests, typecheck and the isolated UI build pass; the full gate has a recorded exit 0. Same-profile wrong-proof refusal and correct reopen pass; fresh-profile refusal and full workflow qualification remain pending. This is separate from native CLI `--approval-key-stdin` and does not automate production human proof or SSH/MFA. Keep synthetic values out of arguments, environment, logs and model context. + +The current acceptance fixture uses the user-selected existing private `versa_azure` provider with model `gpt-5.5-2026-04-24`. This is a fixture choice, not a new default or a relaxation of Crew provider policy. Earlier Qwen results retain their original scope. + +### Institution binding (required work in progress) + +New private SSH connection saves require a canonical institution ID in current source. A shared host receives an explicit initial label that cannot change through a privacy toggle; unlabelled legacy hosts allow human collaboration only until labelled. Local providers may serve any institution; institutional providers must match the host’s institution. Grants and retained session data must preserve that binding through connection/workspace epochs and provider changes. The host confirms its immutable shared label with `privacy set-workspace private --institution ucsf` after `workspace bootstrap` and before tasks/grants. Public/private toggles do not erase that label. Source checks and native build pass; live qualification remains incomplete. + +Crew-scoped copy, diverge and edit-diverge are refused before a child is created, including scopes retained after revocation or expiry. Start a fresh conversation and explicitly grant Crew context. Ordinary conversation derivation retains the union of institution owners.

Machine-readable stdout contains only results/events; prompts/progress go to stderr or the controlling terminal. Avoid storing message bodies, tokens or private paths in a global CLI command history. `watch` cancellation detaches observation; task cancellation is the separate explicit command. + +Mapping to the existing services: + +- Connections use current `/crew/connections` routes. `auth` uses the common authentication coordinator and `connect` then performs the existing cryptographic workspace/node verification. `workspace bootstrap` maps to `auth.bootstrap`; enrollment preparation uses `/crew/devices/prepare`, invitation/accept/revoke use `enrollment.invite`, `auth.enroll`, `enrollment.revoke`. Accept the enrollment token through secure input rather than requiring argv. +- Workspace, members, teams, channels, profile and invitations read the ACL-filtered `workspace.snapshot`. Mutations map to `team.create`, `channel.create`, `channel.archive`, `channel.read`, `profile.update`, `invitation.create`, `invitation.accept`, `channel.transfer`, `transfer.accept`, `membership.revoke`. Transfers preserve current-owner semantics; the broker currently removes the previous owner from channel membership on acceptance (`broker.rs:1705-1721`), which both clients must state accurately. +- History/search/send map to `messages.history`, `messages.search`, `message.post`. Cursor values are opaque strings, not client-generated sequence numbers. Expose body input from stdin/files without shell interpolation; keep the same request ID across an ambiguous retry. +- Files reuse `blob.begin/status/chunk/finish/read` and `reference.create/get`. Upload/commit is separate from publishing an attachment in `message.post`. Download to an explicitly selected output, with bounded streaming, integrity verification and atomic completion; do not trust an attachment name as a local filesystem path. Current desktop transfer cap is 64 MiB, broker per-blob cap is 1 GiB (`CrewFiles.tsx:115`, `broker.rs:2007`); define a shared advertised limit rather than silently presenting those as parity. +- Tasks use existing typed `/runs` start/list/cancel routes; `tasks watch` follows the returned daemon `session_id` through the current session observer API. Never implement task start as generic `run.create` or local `biorouter run`. Preserve provider resolution, posting consent, context-channel selection, idempotency, capacity and unknown-outcome handling already in `routes/crew.rs:380-550`. +- Grants use the existing typed session-grant service, with new sanitized list/revoke routes as needed. The current task list is a local task ledger, not a complete grant inventory: a grant added to an existing conversation need not be a task created by `/runs`. Generic HTTP requests deliberately forbid `run.*`/`worker.*` (`routes/crew.rs:328`); do not bypass that gate to fill the CLI gap. +- Privacy read displays personal connection mode, authoritative workspace policy/epoch, channel classification and effective restrictions. Personal mode uses the existing connection policy update; workspace mode uses `policy.set`. Do not introduce a client-only toggle or a generic “make this data public” command. The existing origin/provider/channel restrictions remain authoritative. + +Not all conceivable chat actions exist today: there is no invitation decline/revoke, team deletion, channel rename, team ownership transfer, or dedicated DM method in the current broker dispatch. Do not advertise these as CLI/GUI parity until implemented once in the shared service. + +## Typed service/client seam + +Add daemon API DTOs under `crates/biorouter/src/crew/api.rs`: typed request/response/error/cursor/event structures, deriving serde and schema traits. Reuse the existing connection/mode types. Keep internal credentials, signing keys and worker bearer tokens out of public DTOs. Move `StartRunRequest`, `RunView` and `GrantSessionRequest` from route-local definitions into that contract. Represent allowed human operations with an explicit tagged enum and per-operation structs; normalize once into the existing signed broker request. Do not publish arbitrary method/JSON passthrough as the user-facing command interface. + +Keep `CrewManager` as the SSH/policy service. Factor task orchestration currently embedded in `routes/crew.rs` into a daemon-owned `CrewTaskService` that receives `AppState`; routes only authenticate, deserialize and call it. Add daemon-owned transfer and room-observer services where orchestration currently exists only in the GUI. This is shared process logic, not a second remote backend or database requirement. + +Extract a reusable Rust `DaemonClient` from the current session client, then expose typed methods through `CrewClient`. It carries endpoint identity, ordinary daemon authentication, caller scope and the separately designed human/worker authority. It must distinguish transport failure, confirmed refusal and unknown mutation outcome. Do not automatically retry a mutation with a new idempotency key. Reuse existing socket non-inheritance and environment scrubbing. Existing CLI JSON transport reads the whole response, and its SSE parser has a narrow current framing assumption; put explicit size bounds and typed stream framing in the extracted client before using it for files/general Crew events. + +Generate desktop OpenAPI types/SDK through the repository generator and migrate `crewApi.ts` to them. GUI and Rust clients then share the same DTO schema and daemon behaviors. Neither copies broker authorization, provider-tier decisions, transfer retry policy, or task admission. + +For room `watch`, initially let the daemon coordinate bounded polling of the existing cursor-based history and snapshots, emitting a typed NDJSON/SSE stream to both clients. Do not duplicate separate polling state machines in React and the CLI. Revalidate access on each poll/reconnect, propagate revocation rather than continue serving stale cached data, drain all pages, preserve cursors, and specify recovery from `stale_cursor`. Session task SSE is reusable for task activity; it does not substitute for a room stream or promise durable room replay. + +## Electron-closed daemon lifecycle + +Existing `apps.rs:226,307` discovers only a fixed loopback/configured port and unauthenticated `/status` success. `/status` returns plain `ok` (`biorouter-server/src/routes/status.rs:16`). Electron intentionally owns a random private port/secret and kills its daemon on app exit (`ui/desktop/src/biorouterd.ts:314,523-545`). `biorouterdSingleton.ts:46` is only an in-process JavaScript singleton. These mechanisms cannot be described as a shared terminal/GUI lifecycle without changes. + +Create one profile-scoped Rust lifecycle implementation, used by both clients. Prefer a global `biorouter daemon start|status|stop` interface, since this is the common daemon, not a new Crew-only process. Ordinary Crew commands may ensure it is running; they must not shut down a reused instance when exiting. + +1. Resolve the same absolute canonical profile identity for both launchers; `Paths` currently accepts relative overrides (`crates/biorouter/src/config/paths.rs:7`). Serialize startup with an early cross-process lock, before mutable services load. +2. Publish an atomic private discovery descriptor containing endpoint, instance/profile identity, PID/start identity and protocol/build compatibility. Authenticate the discovered daemon before reuse; neither PID existence nor an HTTP 200 is sufficient. Credential handoff and terminal proof follow the separate authority design, not a plaintext broadly readable token or inherited model environment. +3. Reuse binary resolution in `commands/exe_path.rs:80`, including installed Windows breadcrumbs and matching packaged binaries. Launch API-only on explicit loopback with intentional profile/environment, without web assets or a browser. `commands/serve.rs:127,342` has useful stop/reap primitives, but its web-bundle dependency and child-ends-with-command behavior must remain separate. +4. Daemon and authentication-session lifetimes outlive attached clients. GUI quit or terminal exit detaches. Explicit daemon stop uses an authenticated portable drain/shutdown operation, reports active tasks, revokes/cleans up as specified and waits boundedly; it never kills a different profile's process or an unrelated external daemon. A native Windows shutdown path cannot assume Unix signals. +5. On restart, restore metadata and mark interrupted runs/SSH transports honestly; do not silently rerun agent prompts or replay unknown mutations. `CrewManager::new` already resets connection statuses to disconnected (`crew/mod.rs:299`). Preserve server ledger unknown-outcome handling and the single-writer lock. + +Acceptance must ultimately cover CLI-only startup/authentication, GUI attachment to the same daemon, GUI closure during a CLI-owned task, concurrent clients and idempotency, absent desktop assets, stale discovery/profile mismatch, grants/ownership/privacy refusal parity, cursor reconnection, resumed transfers, daemon restart, and separately qualified Windows behavior.

The separate API CSV positive and matched backend traces are in [the provider report](local-provider-boundary-report.md). + +## Passing human workflow evidence + +- Alice, Bob, and Carol were simultaneously retained as separate Electron clients using isolated profiles and the then-current daemon `8f0113378714acb7308ce36fd506e145ac26009ed454aae31575e4d8530abed9`. +- All three clients showed `Connected · identity verified` and displayed the same `Synthetic Lab` team and `#general` channel. +- Human messages were visible in `#general`: Alice `Restricted Synthetic Alice message for Crew QA`, Bob `Synthetic Bob human message: hello Alice and Carol`, and Carol `Synthetic Carol human message: hello Alice and Bob`. +- Carol uploaded and shared `crew-cua-fixture.txt`; the UI displayed SHA-256 `709dc5dcf994ac4633ed43861fd8ab87df3ab5abbe67f668b17f9ca524056c42` and `66 bytes`. The downloaded-byte hash matched. This is byte-integrity evidence; this report does not establish a completed user-named native Save. +- Carol created restricted `#small-luna`, invited Bob, and Bob accepted. Alice's channel list did not show it. Ownership transfer to Bob was accepted; Bob then saw one member and Carol's channel list cleared it. + +## Agent and normal-chat observations + +Carol's Settings UI configured Ollama at `http://127.0.0.1:11434`, selected private `qwen3:1.7b`, and showed the model in the Ask my agent dialog. The connection Edit UI saved remote root `/home/carol/work/crew-fixture` and showed execution allowed within that folder. + +An SSH fixture setup created `/home/carol/work/crew-fixture/crew-task.csv` with three rows (`A,10`, `B,20`, `C,30`), 31 bytes, SHA-256 `b8d8853f57f79b6bc9e4c3736b9f7c840e0975ea0606d31cc934349d5606335a`. A fresh native Ask my agent task used relative path `crew-task.csv` and visibly emitted `Using crew__request` and `Requested remote.read`. The native session's View tool details showed `connection_id 55441429-e81c-4991-b1d4-283961df5e18`, method `remote.read`, and path `/tmp/biorouter-crew-dev-carol-clean/biorouter/data/crew/tasks/crew-task.csv`; the exact tool error was `Connection is outside the approved run scope`. The model then emitted a 10-row/42 summary after the refusal; that text is untrusted and is not an actual tool result. This is an agent guidance/invocation failure: the tool refused before file access, so no routing or CSV-read pass is claimed. + +Typing `/crew Please check the latest updates...` into the native `#general` message composer posted the literal text as a human message and emitted no MCP timeline; that composer is not the personal-chat path. In the personal chat composer, the same natural-language request invoked an actual workspace-list tool and the UI showed `Tool status: success Ran Listing Workspace List · Limit: 50 · 1 result ready`, but this is not Crew MCP acceptance evidence. The correct `/crew` grant flow was then exercised: entering `/crew` alone opened Crew, `Connect your current agent conversation to #general`, and `Review access and posting permission`; the dialog showed `/home/carol/work/crew-fixture` and single-process permission, and `Allow this conversation to read and post here` was clicked. A subsequent natural-language CSV task produced an actual tool status error with `Connection ID: 55441429-e81c-4991-b1d4-283961df5e18`, method `remote.read`, and exact refusal `Connection is outside the approved run scope`. This is a real post-grant refusal before file access, pending the fresh daemon/context fix; no CSV result was claimed. + +## Environment evidence + +Earlier direct Electron launches aborted under the restricted command sandbox's AppKit mach lookup. Scoped GUI-permission launches succeeded with disposable Electron bundle copies, so the earlier failure is labeled test-environment launch restriction rather than a product failure. + +For the next fresh conversation after the daemon/context fix, the local Ollama inventory includes `qwen3:8b` (ID `500a1f067a9f`, 5.2 GB) and `qwen3:1.7b` (ID `8f68893c685c`, 1.4 GB). The stronger model was pulled for synthetic-only acceptance; no external credentials or PHI are used. + +## Separate PAM fixture + +A separate disposable Docker fixture (`127.0.0.1:56929`, user `mfa`) was configured with `linux_pam_fixture.sh`, strict pinned host keys, and an isolated Carol profile SSH config alias `pam-luna`. Shell validation passed encrypted-key plus PAM authentication (`id -u` returned `1000`), wrong-secret rejection, and prompt cancellation without remote command output. + +The earlier native Crew Authenticate UI saved a separate `carol-pam-plain` connection and visibly reached `(mfa@127.0.0.1) Password:`. Closing the authentication pane cancelled cleanly. After password submission, the UI exposed the exact stderr `unix_listener: path "/tmp/biorouter-crew-dev-carol-clean/temp/brcrew-3545e6956575/5fc0aeb1-4b33-4683-a34f-b8c57f190f95.NpIScSXNzamu9FyQ" too long for Unix domain socket`, followed by `SSH authentication ended (exit 255)`. The disposable container's SSH log recorded accepted public-key plus accepted keyboard-interactive/PAM authentication before disconnect. The same profile-configured OpenSSH command succeeds in the shell and returns UID 1000. This historical run proved native prompt/cancel and server-side PAM acceptance but failed the app handoff; the fixed-path authentication replay is recorded next. + +Fresh foreground validation against daemon `1ffa69d980d4664b452b2c492100af96fd4055ba3d0e875f076b331fc83b8d86` used the correctly addressed Carol bundle and CDP 9413. The rendered Crew UI selected saved `carol-pam-plain`, reached the native `(mfa@127.0.0.1) Password:` prompt, accepted the synthetic PAM password, and showed `Authentication complete · connect`; this is an authentication-only positive because the saved descriptor still targets the main fixture and was not used to claim a full broker connection. Sanitized screenshots are retained under `docs/research/biorouter-crew/evidence/` (`carol-fresh-ui.png`, `carol-crew-home.png`, `carol-fresh-pam-prompt.png`, `carol-fresh-pam-after-password.png`). + +The same foreground UI then clicked `Close authentication connection`; the terminal pane closed and Crew returned to the disconnected state with its Authenticate action. This cancellation result is retained as `carol-pam-cancelled.png`. + +After the disposable rootless broker was refreshed to Linux artifact `7311f126d0e77f6b7e6f4b75e0ac32b099ff38b4e7757ca04e92737e9ffbc759` on the preserved workspace and socket, all three retained renderers reconnected through their actual Crew pages. Alice (`local-alice`), Bob (`local-bob-clean`), and Carol (`local-carol-clean`) each showed `Connected · identity verified`, `Synthetic Lab`, `#general`, and three members. Each sent a unique synthetic human marker at 07:33:15–16, visible in the shared channel. Carol then selected `/private/tmp/biorouter-crew-ui-attachments/synthetic-crew.png` in the native file picker. The UI reported `Upload verified`, displayed `synthetic-crew.png · 68 bytes`, `Preview image`, and `SHA-256 verified`; the source SHA-256 was `431ced6916a2a21a156e38701afe55bbd7f88969fbbfc56d7fe099d47f265460`. The native download control was invoked, but no deterministic browser download event/path was exposed by the Electron renderer, so no downloaded-file hash is claimed. Connected and PNG upload/preview screenshots are retained alongside the PAM images under `docs/research/biorouter-crew/evidence/`. + +A larger synthetic RGB PNG (`320×180`, 1,619 bytes, SHA-256 `e744b1f1a930305ed1624cfe7d6337c5ec3ff6ed758f06a4a04867b5e28c9026`) was then uploaded and previewed in the actual renderer. The DOM image reported natural dimensions `320×180`; native download handling wrote a temporary file under `/Users/wgu/Downloads/` whose SHA-256 matched the source. An opaque 257-byte binary (`dd31e55fd954d9edc9e29f8e078387f0dd38e8ea832376311820de6322cdb0d1`) was also uploaded and its Download control invoked; the staged native temporary file hash matched exactly. The binary card correctly exposed Download without a preview control. + +These later PNG/binary checks establish upload, preview where supported, shared file-card visibility and downloaded-byte integrity. They do not establish a completed user-named native Save: only hidden `.com.biorouter.luna.carol.*` staging files were found. The exact supported native selectors did not expose a positively identified Save dialog; a separate bounded Luna inspection likewise produced no usable binding. No unrelated window was operated. Copies of staged bytes are test evidence, not completed product saves. All three renderers independently showed all three fresh human markers and both new file cards. + +## Client refresh at `367fe588` + +This foreground relaunch used the copied bundles `BiorouterAliceElectron.app`, `BiorouterBobElectron.app`, and `BiorouterCarolElectron.app`, with CDP ports 9411, 9412, and 9413 and isolated profile roots. Retained foreground exec sessions were Alice 39891, Bob 57336, and Carol 19782. Each renderer loaded `http://localhost:5174/#/?` with title `Biorouter`; each daemon log resolved `/Users/wgu/.codex/worktrees/biorouter-crew/BioRouter/target/debug/biorouterd`. The verified daemon SHA-256 for this refresh is `3133646fa1fc6b6369677f0c6b769b7ead5ce1bd145bf803e38bea29d3f71cc3` (source product commit `367fe588`). After reconnect, all three rendered `Connected · identity verified`, `Synthetic Lab`, `#general`, and `People · 3`. Fresh rendered screenshots are `/private/tmp/final-9411-reconnected.png`, `/private/tmp/final-9412-reconnected.png`, and `/private/tmp/final-9413-reconnected.png`. + +## Model workflows at `367fe588` + +Carol's rendered Ask my agent run used Ollama `qwen3:8b` and `/no_think`, requesting a CSV read followed by processing and attachment. Run `9f1df8bb-2094-4a40-8e47-cdc3da43cd66` maps to session `20260922_2`, in channel `55441429-e81c-4991-b1d4-283961df5e18`. The room displayed four requested reads and an unsupported 10-row/42 summary. A separate read-only backend diagnostic matched all four typed tool requests with error responses: the model supplied that **channel ID as connection_id**, placed `path` at the top level instead of inside `params`, and used the absolute local task directory. Every response was `isError=true`, `Connection is outside the approved run scope`. No file access succeeded in this run; the model summary is rejected. Room progress labels alone do not establish tool arguments or results. + +The separate later session `20260922_4` used correctly nested relative `remote.read(crew-task.csv)`. Its matched response returned the actual 31-byte CSV, SHA-256 `b8d8853f57f79b6bc9e4c3736b9f7c840e0975ea0606d31cc934349d5606335a`, containing three rows. The provider then returned no answer text or tool calls, and the UI reported the explicit Ollama error. This establishes an app-triggered tool-read subset, not completed processing, attachment, or personal-chat posting. No `remote.execute`, `remote.job_status`, or `remote.attach` success is claimed. Backend diagnostics are identified separately from rendered UI observations. + +Source investigation found local working-directory/workspace-map and project-hint injection still active for Crew turns. The follow-up patch suppresses these ambient local inputs for authoritative Crew-scoped sessions and publishes matched typed tool outcomes in the room without copying raw results. Its regressions and fresh app replay are pending at this point in the record; earlier fabricated history has not been rewritten or accepted as evidence. + +## Clean-channel controls at `373acdf5` + +The daemon for this refresh was atomically installed and verified as `6c19b87f661f78a65011b33c00951206aecc14a19cbe75dab6d88a53ae1ca5ef`. Retained foreground sessions after restart were Alice 44170, Bob 57524, and Carol 48026 on CDP 9411/9412/9413. Each rendered `Connected · identity verified`, `Synthetic Lab`, and three members. + +A clean restricted channel `#fresh-control` was created through Carol's rendered UI, then Alice and Bob were invited and accepted through their own rendered clients. Carol's exact single-control task used qwen3:8b and `/no_think` with JSON `{"method":"remote.read","params":{"path":"crew-task.csv"}}`, omitting `connection_id`. The rendered timeline showed `Tool response received: remote.read`; the returned file was 31 bytes with SHA-256 `b8d8853f57f79b6bc9e4c3736b9f7c840e0975ea0606d31cc934349d5606335a` and rows `A,10`, `B,20`, `C,30`. This is a valid tool-backed pass. + +The first separate processing task performed actual `remote.execute`, `remote.job_status`, and `remote.attach`, but the completed Python process returned invalid `Row count: -1` and `Sum: 0`; the attached 19-byte summary was rejected. Its displayed job ID was `fa807bb05226f28b420aab09d9c161bb4e23c0f6bd98df406bfa88595e48611b`, and the displayed attachment identifier was a UUID, not a digest. A correction task explicitly requested `csv.DictReader`, but the model looped through another execute failure and receipt plus a status call without producing a terminal attach/result. No processing pass is claimed. + +Alice and Bob each configured Ollama through their own rendered Settings UI and completed bounded owned tasks. Their first completed sessions contained assistant text and automatic room projection, but no typed Crew calls. A separate later Alice run issued `messages.history` for its current channel. Her selected-source run did not retrieve the human marker from `Synthetic Lab / #general`; no cross-channel positive is claimed. The provider report separates these run/session IDs. + +A visual review of the final screenshots found no clipping, overlap, unreadable controls, or visible credentials. Evidence includes `final2-9411.png`, `final2-9412.png`, `fresh-control-members.png`, `fresh-control-result.png`, `carol-processing-correction.png`, and `alice-cross-channel.png`. + +The separate correction task was cancelled via Carol's rendered `Cancel` control after backend diagnosis found syntax/idempotency failures. A post-cancel model message displayed a markdown “Corrected Solution” with expected `Row count: 3 / Sum: 60`, but no matching tool events; this generated text is rejected as fabricated and is not evidence of cancellation success or processing. + +Security supplied prevalidated `summarize_csv.py` (SHA-256 `901605725a653a05544cd83bb7af79f711321475fb6d812a91cb991cc7f544d6`) with argv `python3 summarize_csv.py crew-task.csv summary.csv`. Carol session `20260922_8` instead issued a generated `python3 -c` script. Its matched status was exit 1 with a Python syntax error, followed by an empty Ollama completion. No attachment occurred; this was not execution of the supplied helper. + +Carol seeded the source channel with the human-only fact `Cross-channel synthetic fact: marker KAPPA-9413 belongs to Carol and is restricted QA data.` An initial no-session `/crew` inspection did not complete navigation. The subsequent exact-command renderer patch and Bob replay below supersede that observation. + +A fresh rendered Carol `/pair` composer accepted exact standalone `/crew`; Enter navigated to `#/crew` without a model turn. That inspection did not complete the no-session grant guidance or a personal model turn. An earlier inability to locate Send was an inspection limitation: Bob’s later replay found the rendered `aria-label="Send message"` control. The footer’s `Unavailable` label describes cost metadata, not provider availability. + +Bob personal-flow evidence: after choosing the private Ollama model through rendered Settings, the personal composer exposed a DOM-backed `aria-label="Send message"` and sent a harmless synthetic greeting; the assistant replied. Standalone `/crew` from that existing personal chat navigated to `#/crew?sessionId=20260922_2`. Bob selected `#fresh-control`, opened the rendered review dialog, and clicked `Allow this conversation to read and post here`, returning to the same personal chat. A natural-language granted Crew read/post request then failed with the rendered provider message `Ollama completed without answer text or tool calls`; no Crew MCP result or post is claimed. Screenshots are retained under evidence. + +Chronology/provenance correction: daemon `1ce50cb31f63dca70c7bb25c571facd1672fe9271801ddbf5e82f5785483e407` is the latest replay artifact; earlier `367fe588`/`6c19b87f...` observations are dated history. The prior processing record that appeared as a helper receipt was backend-correlated to session `20260922_8` / call `peok02fy`: the actual argv was generated `python3 -c`, not the supplied summarize_csv.py helper, and failed with SyntaxError followed by empty provider completion. The later clean helper attempt is session `20260922_9`, whose rendered metadata shows destination `c874aef4-10b5-41d3-99f7-6d6c90c4e644`, context discovery guidance, repeated execute/list/status calls, then UI cancellation. No helper processing pass is claimed. + +The `Unavailable` footer seen in chat is cost metadata, not proof that Ollama was unavailable. Read-only Ollama diagnostics during the final run returned version `0.34.2` and loaded qwen3:8b digest `500a1f067a9f782620b40bee6f7b0c89e17ae61f686b92c24933e4ca4b2b8b41`, 8.2B Q4_K_M, context length 40960. + +Rendered nested tool-details inspection corrected the clean helper classification: session `20260922_9` first used exact argv `["python3","summarize_csv.py","crew-task.csv","summary.csv"]` with idempotency key `abc123` and timeout 30. Job `3dcb6078a21fc8f1d3cd017f6912c732b442dc3f4250ebe5561647ff7e041966` returned status `failed`, exit code 2, stderr `python3: can't open file '/home/carol/work/crew-fixture/summarize_csv.py': [Errno 1] Operation not permitted`, and empty stdout. No attachment was attempted. Later model retries were stopped; this is a helper path/permission failure, not an argv mismatch. + +### 2026-09-22 native-save bounded check (Luna) + +A single bounded native-save check was attempted against the retained Carol client. The rendered Carol page was the actual Crew task renderer on CDP 9413 (`#/pair?resumeSessionId=20260922_9`), and the exact copied app path was `/private/tmp/BiorouterCarolElectron.app` (observed app label `Biorouter Crew Carol`). Native CUA inventory showed the Carol app running, but `getApp("com.biorouter.luna.carol")` returned `Invalid app`, and selecting the exact copied `.app` path returned `Running application not found: com.github.Electron`; selecting the observed label likewise returned `Invalid app`. No unrelated or generic Electron window was selected. + +Because the exact app identity could not be acquired by the supported native selector, no Save dialog was positively identified and no native Save action was performed. No named-file completion or hash is claimed. Existing hidden Electron staging-byte observations remain staging only and are not upgraded by this check. + +### 2026-09-22 signed fixture identity retry (Luna) + +Read-only metadata showed the original copied bundle declared `com.biorouter.luna.carol` in `Info.plist` but reported `Identifier=Electron` under `codesign`. One disposable copy was created at `/private/tmp/BiorouterCarolElectronSigned.app`, assigned `CFBundleIdentifier=com.biorouter.luna.carol.signed` and display name `Biorouter Crew Carol Signed QA`, then ad-hoc signed with `codesign --force --sign - --identifier com.biorouter.luna.carol.signed`. Only Carol’s retained foreground session was stopped and relaunched as exec session `62077` (PID 16262), preserving the Carol profile and CDP 9413; Alice and Bob were untouched. + +Native inventory then showed `Biorouter Crew Carol Signed QA` with id `com.biorouter.luna.carol.signed` running. The exact CUA app-selection call entered `waitingOnApproval` and returned no approval/result before the parent turn was interrupted. No Save dialog was opened and no named-file hash is claimed. The native binding attempt remains pending approval rather than a product Save result. + +### 2026-09-22 Carol post-broker workflow blocker + +After the broker upgrade, Carol’s rendered Crew UI reconnected successfully (`Connected · identity verified`; `local-carol-clean`; Synthetic Lab with #general, #fresh-control, and #processing-clean-2 visible; three people visible). Settings > Models > Switch models then showed current `qwen3:1.7b` and `LOCAL MODEL INVENTORY: 0 installed · 7 available`; qwen3:8b was not available in the visible picker. The provider/model combobox exposed no qwen3:8b option and the UI returned to Home during the bounded selection attempt. No model request, new channel, or processing task was submitted; this is a concrete provider-selection blocker for the required qwen3:8b processing workflow. + +### 2026-09-22 Carol qwen3:8b helper processing success + +Carol reconnected through the rendered Crew UI and the owned-agent panel was configured with `ollama · private`, model `qwen3:8b`, and remote folder `/home/carol/work/crew-fixture`. The task ran in the existing restricted `#processing-clean-2` channel (the visible UI exposed no create-channel control, so this is not labeled a fresh channel). Task conversation: `#/pair?resumeSessionId=20260922_10`. + +The rendered typed `remote.execute` request used connection `8c991d2f-afef-4a3c-9d52-36647b4f76c7`, argv `python3 summarize_csv.py crew-task.csv summary.csv`, idempotency key `unique_key_20260922_1038`, timeout 30, and job ID `66537cc8d2128331cf8de475a43c6ca0b2605f66d4ee13a5439a257cff4e8f67`. `remote.job_status` returned exit code 0, completed status, and `row_count=3 total=60`. The rendered `remote.read` response for `summary.csv` reported 21 bytes, SHA-256 `29f857b262032224f20e849e76bed6907e8e02846835a632c8380b2bafb91ab3`, and bytes `row_count,total\n3,60\n`. The rendered `remote.attach` attached `summary.csv` (21 bytes) with ID `877d8a8e-e47c-41cd-9f9a-a03c99197f7c`. No generated alternate script or expected numeric answer was supplied. + +### 2026-09-22 native CLI MFA and ProxyJump acceptance (Luna) + +A separate disposable CLI profile and synthetic Linux PAM fixture were used after the retained Crew Electron clients were closed. The rebuilt artifacts were hash-checked locally: CLI `784c945022ca661b2cb97c8677686c044061226e00a9fa26bc752b0aa5b2271c`; daemon `5aa6d1c3e539e3c3c635ef0660af599aba51a008f49fa44c12a7c29937d2ded3`. The fixture used strict pinned host keys, an encrypted synthetic Ed25519 key, a synthetic PAM password, and a disposable two-hop localhost ProxyJump. + +The native `biorouter crew auth` flow reached both key-passphrase prompts and the PAM prompt through ProxyJump and returned `authenticated: true` with exit code 0. A follow-up daemon status remained connected after CLI exit, proving the daemon-owned master remained usable. A wrong PAM secret was rejected by the fixture, and Ctrl-C at the PAM prompt returned an authentication-ended error without authenticating. An initial zero-size PTY was rejected with `Invalid authentication terminal size`; an explicit 24x80 PTY then passed. File-only sweeps over the disposable profile and fixture logs found no synthetic key passphrase or PAM secret. No retained workspace, production account, or model was involved. + +### 2026-09-22 desktop artifact preparation (Luna; no GUI launch) + +A bounded preparation pass for product `906bf68b` and workflow `0fb6cd13` completed the Electron main, preload, and renderer builds, and `tsc --noEmit` passed. The existing pinned backend pair was verified locally. This section records build preparation only: no app launch, profile change, native CUA retry, or GUI acceptance occurred, and the CLI-only condition remained active. diff --git a/docs/research/biorouter-crew/desktop-integration-handoff.md b/docs/research/biorouter-crew/desktop-integration-handoff.md new file mode 100644 index 000000000..a32864d89 --- /dev/null +++ b/docs/research/biorouter-crew/desktop-integration-handoff.md @@ -0,0 +1,48 @@ +# Crew desktop integration handoff + +Implementation worktree: `/Users/wgu/.codex/worktrees/biorouter-crew/BioRouter`, branch `codex/biorouter-crew`.

Inherited credential environment variables are removed, keyring is disabled, and the transport's development-only key store is profile scoped. Native SSH authentication also removes inherited credential variables and the personal SSH agent. The transport explicitly selects profile SSH configuration, identities, and known_hosts. Provision verified fixture keys under each profile independently; never copy a participant's provider credentials into another profile. + +Crew's header displays the profile name; the connected channel header displays the verified remote SSH username. These are presentation aids, not a substitute for Luna's process/path/hash verification. + +## UI and API integration + +`/crew` is a native sidebar route and is available from provider onboarding without choosing a model. All Crew HTTP requests, including metadata reads, use the existing daemon secret and per-request user-action proof. + +The ordinary-chat `/crew` command carries an existing session ID into `/crew?sessionId=...`. The channel page offers an explicit destination/context grant dialog. Its submit calls the parent's typed session-grant route. The server's idle-turn guard returns its actionable refusal directly into the still-open dialog; the UI does not navigate away or announce success after a refusal. On success it returns to that exact session. Provider identity and authorization remain backend resolved. + +Owned execution cards use the parent's typed `/runs` API, not broker grant records as invented execution status. They open the actual session for approvals and detailed activity. Cancellation is enabled only for active local-owned run records. + +SSH authentication is a narrow main-process IPC accepting only a saved connection ID. Main fetches the authenticated daemon plan itself and directly starts native `ssh` under node-pty. Exact owner/connection/plan identity reuses an existing master. Route navigation detaches its terminal display while preserving the master for ordinary chat; explicit Close disposes the exact PTY. Renderer reload/crash/closure and app teardown retain the existing owner-scoped registry cleanup. The transport separately closes its exact control socket on disconnect/removal/update. No prompt transcript or input is persisted. Native host-key checking remains strict; the UI gives independent-verification and known-hosts import instructions, with no trust-on-first-use shortcut. + +## File behavior + +Uploads are bounded at 64 MiB to bound browser hashing/download memory. Larger data can be shared through the broker's real restricted `reference.create`/`reference.get` API. References are clearly marked as metadata only: not uploaded, existence/access not verified, and never executed or fetched by preview. `message.post.references` carries the opaque reference IDs. + +Pending upload recovery persists only a bounded list of connection/channel/blob IDs, byte size, SHA-256, request idempotency key, and timestamp in profile-scoped renderer storage. It stores no filename, local path, bytes, credentials, or conversation history. The begin key is saved before the first remote admission. After restarting, the user chooses Resume/restore: an incomplete transfer requires reselecting matching size/hash bytes, and the broker's current offset is authoritative. A completed unsent upload can be restored to the composer without retransferring bytes. Successful message publication removes corresponding recovery metadata. Invalid metadata produces an explicit refusal and a local-record reset control; forgetting a record does not delete remote objects. + +Downloads check SHA-256 before exposing a result. Raster previews are limited to PNG/JPEG/GIF/WebP; PDF and arbitrary files remain downloads. Downloads resume in memory while the view stays mounted, and are discarded on leaving the view. Offline channel history caching remains off. + +## Validation status + +No test, build, fixture launch, or computer-use action was executed by the UI implementation lane. Earlier Luna checks identified TypeScript issues and a filename-sanitizer lint issue, which were corrected. Restart recovery, remote-reference integration, auth-master route survival, accessibility, and the final source revision require Luna's current checks.

The capture +contains 11 stream lines. Bob's A membership was restored through an ordinary +invitation and acceptance afterward. + +This establishes bounded initial-history delivery and explicit terminal +invalidation after source revocation. The derived/history frames had already +reached the CLI pipe while authorized; this does not prove behavior with a +derived frame still in the daemon queue at revocation, or retroactive erasure +of delivered bytes. The complete queued-derived race matrix remains open. + +## Stable mutation identity + +Alice sent a small synthetic message with request ID +`luna-7ab-idem-20260923-03`. The first send and identical retry returned the +same message receipt, `5dae549b-2ce4-49a4-9f7a-a513da1f1ac8`. Bob's independent +history contained exactly one matching message. Reusing the request ID with a +different body exited 1 with `conflict: idempotency key reused with different +request` and added no second message. A preliminary Alice discovery failure +preceded the successful run; her owned daemon was restarted through supported +lifecycle and vault/authentication flows. + +A separate attempted reference mutation on Bob's profile stopped at daemon +discovery and did not publish anything. Independent source/fixture inspection +established a wrong-case `BKx8iO` root instead of `bKx8iO` in the harness. +Both spellings identify the same directory on the case-insensitive filesystem, +so its `-d` fallback never ran. Configuration identity canonicalizes its path, +but runtime discovery correctly rejects the differing literal socket path. +No production gate or descriptor was changed. The attempted `--reference` +argument also used a message ID, whereas that flag accepts remote file-reference +IDs. That failed attempt is not reference-semantic evidence. + +After a later explicit authentication/reconnection, retained typed outputs show +Bob connected in Private mode, a Bob workspace snapshot, and remote-file +reference `24156095-3050-4279-ad2b-298a626e165f` with `verified=false`. +The successful send receipt is message +`242b0c50-8235-4636-840f-2b7d4f9c0840`, body `remote-reference-send-7ab`, with +exactly that reference.

Ordered `remote.execute`, `remote.job_status`, and `remote.hash`; output SHA-256 `f1ff17176d0b566c832f5e6dbbeafe912d93b6f7a0548204c9d551cb1fab3c0a`, 18 bytes. The exact remote job record independently reported `completed`, exit code `0`, and matched run ID. | +| Public control/private denial | PASS | Synthetic public sink received one control request. Private-mode public-model request was refused with `Private cluster blocks public models`; sink count remained one. | +| Baseline watch and detach | PASS | One canary event was observed; Ctrl-C detached with exit code 0. | +| SIGSTOP/cancel/drain | PASS | Fresh broker was stopped, watcher was cancelled while stopped, broker resumed within two seconds, and the next supported history request succeeded. | +| Watch revocation/drain | PASS | Carol’s active watch ended with `channel_access_changed` after owner revocation; a subsequent owner post was not delivered to Carol. | +| Pause with concurrent post | OBSERVATION | Posting while the broker was stopped produced an observation refusal/stale-cursor message and a subsequent broken pipe. Explicit disconnect/connect restored history. No causal product conclusion is made. | +| Mixed-artifact pause/post probe | INVALIDATED | The test CLI and running Alice daemon were from different mutable-target phases; its observer framing error is excluded from acceptance. | +| Matched-906 pause/post/drain | PASS | After explicit reconnect and vault unlock, the structured baseline watch remained alive for one second. Broker SIGSTOP was followed by asynchronous post, SIGCONT after 0.575 seconds, 21 drained watch lines including the post, Ctrl-C exit 0, and history marker count exactly one. | +| Matched-906 live watch identity control | PASS | A separate control post was observed live and in history with the same message ID and body; post and history exited 0. Retained evidence is `/private/tmp/crew-cli-parity-final-luna/watch-exact-906.json`. | +| Observer slot admission/release | PASS | On a new private synthetic channel, 16 observers stayed alive for three seconds; the 17th returned HTTP 429 `Crew observer refused (429 Too Many Requests)`; after detaching one, a replacement observer stayed alive. All owned observers then detached cleanly. | +| Adaptive oversized history | PASS | A new private channel received 20 distinct 59,983-byte messages. `history --limit 200` returned broker `response_too_large` / `Request a smaller history window`. Default watch drained 20 direct message frames, all 20 seeded IDs and body hashes matched, with no missing or duplicate IDs and clean exit 0. | +| Expected-mode public file refusal | PASS | On the verified private connection, `files upload --expected-mode public` with a nonexistent local path refused with `Crew connection privacy changed; refresh the verified workspace before selecting a file`; local file selection was never reached. | +| Expected-mode private file upload | PASS | The same private connection accepted the existing 43-byte synthetic file and completed with SHA-256 `d5231aa05fefa605797ecc8e3ac2098e2903385d2e02bcdaa664e4d26a5836ff`. | +| Saved-public versus expected-private | PASS | A supported descriptor update changed only the saved mode to public; `files upload --expected-mode private` refused before transfer with the same privacy-change error. The exact private descriptor was restored and reconnect succeeded. | +| Resume reselection versus saved-public | PASS | CLI `files resume` reselected the local file after saved mode was changed to public; `--expected-mode private` refused before transfer with the same privacy-change error. This is reselection evidence, not opaque-capability reuse. The exact private descriptor was restored and reconnect succeeded. | +| API capability versus saved-public | PASS | Supported `POST /crew/files` registered a private 43-byte capability. After a supported saved-public flip, `POST /crew/transfers` reused that capability with the same request ID and no path reselection; it returned 400 `Local file approval does not match this transfer`. The before/after transfer list contained no receipt for that request ID. Private mode and reconnect were restored. | +| Task expected-private versus saved-public | PASS | With saved mode public, `tasks start --expected-mode private --allow-posting` returned an admission refusal: `Crew connection privacy changed; refresh the verified workspace before granting agent access`. No independent provider-request counter was measured; no provider dispatch follows the reviewed admission guard order. The exact private descriptor was restored and reconnect succeeded. | +| Selected-context first attempt | FAIL | The task returned the prior helper output hash instead of the fresh canary hash. The cause is unproven; no stale-history explanation is asserted. | +| Selected-context isolated repeat | PASS | New empty destination and new single-message source; the prompt omitted the canary value. The model retrieved the exact canary. Independent canary-value SHA-256: `eab33425f6b39d8137463cbc52d1704f41b888148092d17689345c73ed24fdaf`. | +| Unauthorized source history | PASS | Carol’s source read was refused with `forbidden: channel unavailable`; no source value was retrieved. | +| Unauthorized source task admission | PASS | Carol’s task on an authorized destination with Alice-only source context was refused before run/provider creation with `forbidden: channel unavailable`. | + +## Reproduction shape + +The checks used supported CLI operations conceptually equivalent to: + +```text +biorouter crew connections prepare/save +biorouter crew workspace bootstrap +biorouter crew enroll invite/accept +biorouter crew teams/channels create +biorouter crew send +biorouter crew files upload/status/download +biorouter crew files pause/resume +biorouter crew daemon stop +biorouter crew daemon start +biorouter crew credentials unlock +biorouter crew connect +biorouter crew connections update - +biorouter crew files upload +biorouter crew files status +HTTP POST /crew/files +HTTP POST /crew/transfers +HTTP GET /crew/transfers +biorouter crew tasks start/show +biorouter crew history/watch +``` + +Approval and vault inputs were supplied through the documented secret stdin +paths.

A later mutable-target probe measured CLI +`4095d6e2b902be43273535de61fd3eb323a757eb1c49b8470cf67e61ff7437a8` and +daemon `45d42240af92ce4a0d43618bd4d496249f095fcdad88af768ad9f2ecd086baa9`, +but the running daemon image could not be inferred from those replaced path +files; that probe is excluded from acceptance evidence. + +The matched-906 observer first emitted a structured baseline message carrying +`id`, `body`, `channel_id`, and `sequence`, and remained alive for one second +before the broker fault. Its output was continuously drained. After SIGCONT, +the asynchronous post appeared in 21 drained lines, and a fresh history page +contained the marker exactly once. Retained JSON evidence is +`/private/tmp/crew-cli-parity-final-luna/pause-post-906.json`. + +## Personal natural-language Crew MCP post/read and revocation + +Fresh Alice personal session `20260922_7` started with the local Ollama +model (`qwen3:8b`) and Crew builtin. A harmless first turn completed with +`PERSONAL_READY`; no human secret was included in the prompt. The supported +CLI grant supplied the human approval key only through stdin: + +```text +biorouter crew --no-start --connection --approval-key-stdin \ + grants grant 20260922_7 2d6ed29f-455e-4212-9c38-9ece2301d875 +``` + +The grant returned run `d5527b98-0969-478c-bb03-4b9e41c4833a`. An ordinary +natural-language `session send` turn invoked `crew__connections`, then +`crew__request` with the supported `run.project` posting method, then +`messages.history` for the same selected channel. The model reported posted +message ID `955187be-7031-4596-9a14-56a9ad2224f0` and body +`PERSONAL_MCP_POST_20260922_7`; the body matched the history result. This is +actual personal-session MCP evidence, separate from GUI acceptance. + +The initial prompt intentionally requested unsupported `message.post`; the +typed Crew response refused that method and listed supported methods. No +message was claimed from that attempt. The corrected `run.project` call is the +supported owned-agent update/post path. + +The grant was then revoked with the supported CLI command. A follow-up +natural-language turn attempted one connection lookup and one history request; +the daemon refused inference before tool execution with the exact sanitized +error `Crew run was revoked; request a fresh human grant`. No channel data was +returned after revocation. + +This case used observer artifacts: CLI +`0450257748d1870047ee311cccd387a66f950b12de562ca6eeb440523d34a197`, daemon +`56e254bc6a7b1c1a1f51404c19c5f4d9f6d869fb4f13edf97f0f35aee5a52d1f`, and +Linux broker `4f11d8586b093a6616f0d8231930112369e990165e1adfce88b6a2bdb031351a`. + +## Authority and provider-counter API checks + +The bounded isolated loopback-provider harness was run with daemon +`45d42240af92ce4a0d43618bd4d496249f095fcdad88af768ad9f2ecd086baa9` and Linux +broker `4f11d8586b093a6616f0d8231930112369e990165e1adfce88b6a2bdb031351a`. +The public control run completed and produced exactly one loopback sink request. +After switching the synthetic connection to private mode, an equivalent public +provider run was refused with `crew_request_refused: Private cluster blocks +public models`; the sink count remained exactly one. This is local loopback +provider evidence and does not use an external provider. + +On the fresh Alice daemon, direct `POST /crew/files` attempts with a synthetic +file and both missing and wrong `X-User-Action` proof returned HTTP 403 +`crew_transfer_refused` with `A verified human action is required for local file +and transfer access; agent grants and API keys do not authorize it`. A +human-authenticated read-only transfer list contained six existing receipts and +no receipt with either negative-test request ID. No file or transfer side effect +was observed. + +The same isolated loopback harness exercised foreign-owner cancellation: the +wrong connection returned HTTP 400 `crew_request_refused` with `This task is not +owned by this device and connection.` The owned cancellation returned 200 with +`cancelled: true`, `remote_revocation_confirmed: true`, and one cancelled finish +event; a completion-first cancellation returned `already_finished: true` and +`cancelled: false`. The sink saw two requests total (one held cancellation run, +one completion control), with no late completion overwriting cancellation. + +## Follow-up observer backpressure attempt + +The pinned daemon hash was rechecked directly: +`45d42240af92ce4a0d43618bd4d496249f095fcdad88af768ad9f2ecd086baa9`. +No backpressure pass is claimed. A slow-reader attempt against the retained +adaptive channel exited before the eight-second unread interval with +`observation_refused`: `Room observation ended ... a stale cursor requires an +explicit fresh history selection`. A fresh private channel creation was then +attempted twice on the connected Alice profile; both returned HTTP 400 +`Broken pipe (os error 32)`. Read-only status immediately afterward confirmed +the daemon remained connected/private with no last error. Because a fresh +channel could not be admitted and the retained channel had a stale cursor, +slow-reader expiry, fairness under sustained backlog, and ACL-revocation +transport recovery remain unexecuted rather than inferred from this attempt. + +## Pinned 9a restart diagnosis + +The owned Alice daemon was stopped and restarted with the pinned 9a pair (CLI +`9bbedb34c349e3b637c8b8e01e6e4e50807ffa86bf1bcfaa1562fc3c64195c5f`, daemon +`50eefaaebad298679d9ad525a98a911941ea8ff62c462033a389fcd3351b005f`). Vault +unlock succeeded. Immediate history then refused with the typed state +`Crew connection is disconnected; authenticate and connect in Crew`. A fresh +supported connect failed with `Crew SSH read failed; reconnect. Submitted +operation outcome may be unknown; inspect history before retrying` (HTTP 400). +The test stopped at this first actionable failure and did not retry a possibly +unknown operation. The earlier direct bridge probe is separate evidence; this +is a reproducible higher-level connect failure after the pinned daemon restart. + +The original host-trust refusal is classified as fixture setup: the daemon +process had not inherited the owned profile SSH environment, even though the +profile and verified source known-hosts records matched. After restarting the +owned daemon with that profile environment (without changing host keys), native +authentication succeeded with exit 0 and `authenticated: true`. + +With the authenticated 9a session, immediate small history succeeded in 0.036 +seconds. The following adaptive history request correctly returned +`response_too_large` / `Request a smaller history window` in 0.065 seconds, and +the next small history request succeeded in 0.031 seconds. This is a bounded +current-artifact history recovery sequence; it does not qualify slow-reader +backpressure or fairness. + +## Pinned 9a transfer checks + +One fresh synthetic upload capability registered with HTTP 200. The transfer +completed with HTTP 200 and the receipt SHA-256 matched the local synthetic +file (`de436eaab40d2aa3ac514b47098f6fbf8d6b7bb5dd8e7bd615160763243d5cf9`). A +same-request replay was refused with HTTP 400 and did not create a second +receipt; the completed receipt remained the only outcome for that request ID. + +After registering another capability, changing the selected source before +start returned HTTP 400 `The selected source changed; select the original file +again`. A missing path returned HTTP 400 `No such file or directory (os error +2)`; creating that path afterward did not turn the refused selection into an +approved capability. These checks used fresh request IDs and human proof. + +## Pinned 9a download-capability checks + +The completed synthetic upload supplied a blob for the download contract. A +download selection registered with `approval_pending: true` returned HTTP 200; +confirmation of the unchanged destination returned HTTP 200, and transfer +start completed HTTP 200. The destination sentinel was replaced by the blob, +with resulting SHA-256 +`de436eaab40d2aa3ac514b47098f6fbf8d6b7bb5dd8e7bd615160763243d5cf9`. + +Changing an existing destination after registration but before confirmation +returned HTTP 400 `Destination changed since selection; select it again to +approve publication`, and the replacement sentinel remained. Registering an +initially absent destination succeeded as a pending selection, but creating the +path before confirmation produced the same HTTP 400 refusal and preserved its +sentinel. Missing and wrong proof on confirmation both returned HTTP 403 with +the verified-human-action refusal. + +A fresh registration using the completed download’s original request ID, +directory/name, overwrite choice, and blob returned a replay capability. +Confirmation and start both returned HTTP 200, the original receipt ID was +returned, and the destination hash was unchanged. This is the receipt-bound +download replay; it is distinct from reusing a consumed capability. + +After confirming an unchanged existing destination, the destination was +replaced before publication. Transfer start returned HTTP 200 with a receipt, +but the receipt settled as `needs_file_selection` with +`Transfer stopped. Reselect the original local file or destination to resume. +Inspect any unconfirmed publication before retrying.` The replacement sentinel +and its SHA-256 remained unchanged, while no download bytes were written. This +is the post-confirm mutation refusal represented as a durable needs-selection +outcome rather than a second local overwrite. + +A fresh 32 MiB synthetic download was started and paused at offset 262,144; +the persisted receipt was `needs_file_selection`. After daemon restart, vault +unlock and native PTY authentication, a new destination selection bound to the +same receipt resumed successfully. The final receipt reached `completed` at +offset 33,554,432; the downloaded file was 33,554,432 bytes and its SHA-256 +matched the receipt (`56a388beba6bfe73739e2d0e635a4617e8e649bb69bea6109b8417af259fd7be`). + +Receipt-bound cleanup was then exercised against the owned post-confirm +needs-selection receipt. Cleanup registration and deletion returned HTTP 200; +the receipt disappeared from the transfer list, while its destination hash and +an unrelated sentinel file remained unchanged. + +A separate paused 32 MiB download reached `downloading` before pause, with +receipt offset 1,572,864 and an actual hidden partial file of the same size. +Receipt-bound cleanup returned HTTP 200, removed the receipt and that partial +file, and left the unrelated sentinel unchanged. The final transfer list no +longer contained the receipt. + +## Pinned 4a observer-lane setup outcome + +The owned Alice daemon was restarted with the pinned 4a CLI/daemon pair, but +the first supported status/auth call stopped before credential handling with +`Daemon identity could not be verified; refusing replacement: Operation not +permitted (os error 1)`. The observer slow-reader, backlog fairness, and +revocation-buffer checks were not run against 4a; no identity guard was bypassed. + +## Broken-pipe recovery diagnosis + +The owned Alice profile was checked after the observer attempt. Read-only status +reported the connection `connected`, mode `private`, and `last_error: null`. +The retained broker process was alive (PID 5350) and its owned stdio bridge was +also alive. A simple history request still returned HTTP 400 `Broken pipe (os +error 32)`. An explicit supported disconnect completed successfully; a fresh +supported connect completed in 0.094 seconds and returned the same connection +identity, workspace, and socket, but a subsequent status/history round-trip +still reproduced the same broken-pipe history error. The broker log contained +only its startup metadata and no additional sanitized error category. + +This isolates the observation failure to the bridge/backend request path after +reconnect, rather than proving a stopped broker or evicted product connection. +No process was killed, no profile state was edited, and no backpressure pass is +claimed. + +## Direct SSH bridge protocol isolation + +One fresh strict-host-key SSH bridge session was opened using the owned Alice +fixture. Two successive public `hello` frames and one synthetic +`auth.challenge` frame each received a valid response: 3/3 responses, at about +0.071 seconds elapsed by the third frame. The challenge response had the +expected synthetic workspace/UID shape; nonce, signatures, endpoint details, +and credential material were discarded. The probe then terminated its own SSH +process, so its exit 255 is expected cleanup rather than a bridge failure. + +This shows the SSH bridge and broker can answer successive direct frames while +the higher-level daemon history request still returns broken pipe. It narrows +the unresolved problem to the daemon request/response path or its bridge +session lifecycle; it does not qualify observer backpressure or recovery. + +## 9a connect versus direct bridge comparison + +Using the same saved target and configuration, one fresh strict SSH bridge +`hello` received a valid result in 0.071 seconds while saved connection status +remained `disconnected` with no stored last error. The intentionally terminated +probe exited 255 during cleanup. Aggregate read-only process-state counts in +the synthetic container were 7 Alice running-state entries, 4 Bob, 4 Carol, +and 58 Alice zombie entries; no process was modified. The bridge therefore +answered and the failure is not a simple listener absence. The zombie count is +fixture-health context only and is not asserted as causal. + +## 9a native auth follow-up + +After the pinned daemon restart, the supported native `crew auth` flow was +attempted with the owned profile’s explicit approval input and its profile SSH +configuration.

A private, +loopback deterministic provider called actual Crew tools: `context.manifest` +returned A's canary, and `run.project` posted a derived result to B. Removing +Bob only from A made his next context turn fail with +`grant_expired: run revoked, expired or policy changed` before any provider +request. The provider audit delta was zero and the canary was absent from the +failed output. Bob retained B membership. + +A positive visibility control re-invited Bob into A. B history then contained +one instance of derived message `b31210b8-aecc-4cbb-82d1-1d98f02f4474`. Removing +Bob only from A again hid that message, while B-only human control message +`fee9ad65-5245-435c-914d-7fd62c27b748` remained visible exactly once. This matches +the broker's requirement to retain access to every source of a derived message; +the earlier empty B page was expected filtering, not a membership defect. + +These cases establish bounded observer and provider admission behavior. They +do not claim retroactive removal of bytes already delivered while authorized, +or a complete queued-derived-observer race matrix. + +A later paused B observer started from a latest-history cursor after the +derived message, so that message was not eligible for stream delivery. Of +three B-only controls sent before A revocation and two afterward, the resumed +reader received one earlier frame, then terminated with an error indication. +The harness did not retain the exact error frame/code. A fresh B-only control +remained visible in Bob's direct history, but a bounded reconnect-stream read +yielded no frame. This attempt establishes neither queued-derived exclusion +nor reconnect catch-up; those cases remain unqualified. The earlier frame may +already have been in the OS pipe when membership changed. + +## Interactive terminal continuation recovery + +A separate fresh profile and loopback synthetic streaming provider exercised +ordinary daemon admission and an actual terminal client. Noninteractive pending +resume refused before dispatch. Interactive leave preserved the claim, abandon +resolved it, and takeover admitted exactly one explicit successor input whose +response persisted in the authoritative session. Final resume showed no active +turn or pending continuation. The [validation report](../validation-report.md) +records the focused tests and ordinary API flow. + +## Three-user natural-model and file workflow + +Bob's ordinary shared-daemon session `20260923_3` used the installed local +Ollama endpoint and `qwen3:8b`, with an explicit destination/context grant. +Actual `crew__connections`, `messages.history` and `run.project` calls read +seeded fact `549cb19a-925d-450d-b1e0-9795f12284ae` and posted progress receipt +`0f75d697-a608-408c-aca2-20f3f2c30f50`. Alice and Carol independently fetched +the destination and each found the fact and model result exactly once. The +stream finished normally. This used the installed model, separately from the +deterministic provider fixture used for precise revocation assertions. + +The attachment upload initially returned transfer +`17a75769d6ac4fb286582d9d0ca3f960` in `starting` state, without a blob ID. +Using that transfer ID prematurely was refused as `attachment unavailable`. +The supported `files watch` flow reached `completed` and returned blob +`4465105b-6a1e-4a51-bade-b8240f0d26ef`. Alice posted attachment message +`66f51992-399d-4f9f-8e0f-2a48f43d5627`; Bob and Carol independently read it, +downloaded the completed blob and waited for their download transfers to +complete. Both files matched the original SHA-256: +`4fd7fd53f52ec3ba906e93b9f6f4ecf7690c1e7b8f703cb5c3836952f3fee4cf`. +This qualifies the bounded three-user native CLI attachment workflow; native +graphical Save dialogs remain a separate acceptance gate. + +## Remaining scope + +The [Linux report](linux-532c3b7d-20260923.md) records the same source's ARM64 +build, focused regressions and ordinary-UID lifecycle.

The final assistant output cited the returned Crew receipt and did not claim success before the tool result.

All profiles, credentials, and channel identifiers remain private to this lane. + +## Observer lane (bounded) + +A fresh history selection was required before observation: starting `watch --after 0` returned the broker's explicit `stale_cursor` error and ended observation. Refreshing with the cursor from `history --latest --limit 1` allowed a fresh watch. With the refreshed cursor, six authenticated sends (`observer-burst-1` through `observer-burst-6`) were observed by the watch stream; all six markers were received. + +A slow-reader probe then consumed the watch stream at 0.5 seconds per line. The reader consumed four lines, while the concurrent sender stopped making progress within the bounded 30-second command window, observing a slow-reader arrangement; the initial compound shell also waited on the watch/pipe lifecycle. Cause of that shell-level stall was unproven. A follow-up per-request probe used the refreshed cursor, a 0.5-second reader, and four independent sender subprocesses with 3-second per-request timeouts: reader consumed 3 frames, and all four sends completed in 0.016–0.042 seconds. After reader termination, an independent send and latest history read completed in 0.042 and 0.037 seconds, respectively, and the marker was present. Thus the earlier 30-second compound-command stall must not be treated as a transport liveness or backpressure failure. The exact owned watcher/probe processes were terminated after their bounds. This probe does not claim fairness or revoked-buffer semantics: no fair concurrent backlog or post-revocation transport-delivery distinction was asserted from this run. + + +## Redacted reproduction templates + +All commands below were run with fresh lane-owned profile roots and secrets supplied only through stdin; concrete roots, connection identifiers, channel identifiers, and approval values are omitted. + +```sh +BIOROUTER_PATH_ROOT= HOME=/home \ + biorouter crew --no-start --approval-key-stdin --connection \ + send --text --output-format json + +BIOROUTER_PATH_ROOT= HOME=/home \ + biorouter crew --no-start --approval-key-stdin --connection \ + history --latest --limit 100 --output-format json + +BIOROUTER_PATH_ROOT= HOME=/home \ + biorouter crew --no-start --approval-key-stdin --connection \ + watch --after --output-format stream-json +``` + +Baseline send/read completed in 0.044/0.036 seconds. In the slow-reader probe, each of four sender subprocesses had a 3-second timeout; all four completed, while the reader consumed three frames at 0.5 seconds per frame. Post-reader-close send/read completed in 0.042/0.037 seconds. Bob and Carol independent history verification was attempted with their fresh profiles but both required interactive SSH host-key/MFA reauthentication; the supported noninteractive command returned that explicit fixture-auth requirement, so receipt visibility for those two clients remains unverified. + +## Large observer backlog stress (2026-09-23) + +Before this stress test, Bob and Carol's fresh daemons were restarted with their +intended `BIOROUTER_DEV_PROFILE_ROOT`. Supported interactive TTY authentication, +fresh approval/vault credentials and strict fixture known hosts restored both +connections. Each user's independent history then contained receipt +`45029dbb-c658-4aeb-9c25-c728a4f081ca` and the synthetic progress marker. +This resolves the fixture-authentication prerequisite recorded above and +establishes cross-user visibility for that specific model-generated post. + +The fresh Alice profile seeded 60 authenticated messages, each approximately 50 KiB, with zero send errors and 60 broker acknowledgements. A watch stream was opened from the pre-backlog history cursor and its stdout reader was intentionally paused for 6 seconds. During that pause, independent Bob operations remained responsive: human post completed in 0.230 seconds and latest-history read completed in 0.028 seconds, each under the predefined 3-second operation timeout. + +After the reader resumed, only 12 unique backlog markers were received across 13 stream lines; the watch exited nonzero with `Crew observation ended without a reconnect frame`. This is an observed observer catch-up/liveness defect under a paused large backlog, not a pass. The same harness with 20 approximately 50 KiB messages and immediate consumption received all 20; therefore the failure is tied to paused pipe/socket consumption and not simply message size. A 20-message 1 KiB diagnostic backlog also received all 20 after the pause. Persisted-history verification of the full 60-message large response was refused by the broker as `response_too_large` when requesting a 100-message window; the 60 individual sends were acknowledged before observation. + +Reproduction arrangement: one fresh Alice watch subprocess writes stream-json to a pipe whose reader consumes nothing for 6 seconds; an independent Bob CLI subprocess posts a small marker and a separate Bob latest-history request, each with a 3-second timeout; then the reader drains and counts unique message markers. All credentials are stdin-only and redacted from this report. This requires an Astra fix request for observer reconnect/catch-up handling under large paused output; no source change was made in this lane. Fairness across multiple observer streams and revoked-source queued-context behavior remain unverified. diff --git a/docs/research/biorouter-crew/evidence/source-only-history-20260922.md b/docs/research/biorouter-crew/evidence/source-only-history-20260922.md new file mode 100644 index 000000000..2553d23b7 --- /dev/null +++ b/docs/research/biorouter-crew/evidence/source-only-history-20260922.md @@ -0,0 +1,23 @@ +# Source-only history provenance + +The unpublished screenshot-only commit was removed before publication.

EC2 was asked about each row directly, and each is terminated or `NotFound`. +- **Keys.** The bootstrap key and all eleven users' private and public keys are absent. No file with + any of those names exists anywhere under `/private/tmp/crew-ui-redesign`. + - A content sweep for private-key blocks, with a positive control, finds only the round-4 + security critic's synthetic decoys in the fourth profile's home. None of them matches a fixture + public key. +- **Versa key.** The single `VERSA_AZURE_API_KEY` line was deleted from all 16 QA `secrets.yaml` + files: the eleven live profiles, `secjoin`, and four in the earlier `fixture/profiles`. The files + are kept, now empty and still 0600. + - A search for the key's value, rather than for file names, found one more copy. The round-4 + security critic had hard-linked the fourth profile's `secrets.yaml` as a decoy, and rewriting + `secrets.yaml` left the old contents alive under that name alone. That copy was stripped too, + and the value now appears in no file under the stage tree. + - The unused `secjoin` profile directory was removed. + - The preserved source profile and `~/.config/biorouter` were not touched. + +## Live QA rounds + +Each round redeployed the stage in place: brokers upgraded as each user over their own key and +restarted by their owners with identical arguments, daemons and apps restarted from the new +artifacts. Every broker journal was byte-identical across every restart (chen-lab 92 → 170 → 223 → +233 lines at rounds 2, 3, 4 and final), and snapshots before and after matched in every part. +Fresh critics then drove the real apps through Chrome DevTools, with drag and paste sent as CDP +events and the native share confirmation answered by the development gate +`BIOROUTER_DEV_AUTO_CONFIRM_SHARE=1` from round 3 on. + +| | Round 1 | Round 2 | Round 3 | Round 4 | +|---|---|---|---|---| +| Build | `5959ebdc` | `5b079379` | `ac02e57a` | `b1c87edc` | +| Critics | Alice (host); Bob, Carol, Dave, Erin (join); security; a11y | Alice, Frank (new), Erin, Bob, Carol, Dave; security; a11y | Henry and Gina (new), Dave, Bob, Erin, Carol; security | Iris and Jack (new), Gina, Bob, Erin, Carol; security | +| Novice tasks | 38 | 49 | 60 | 56 | +| Unaided | 15 | 28 | 51 | 51 | +| With friction or partial | 17, plus 1 answered "no" | 14 | 8 | 3 | +| Failed | 5 | 7 | 1 | 2 | +| **Unaided rate** | **39%** | **57%** | **85%** | **91%** | +| Findings P0 / P1 / P2 | 5 / 23 / 41 | 0 / 16 / 62 | 0 / 5 / 58 | 0 / 3 / 54 | +| Earlier findings verified fixed | — | 49 of round 1 | 54 of round 2 | 36 of round 3 | +| Design score (Carol) | about 4½ | 7 | 8.5 | 9 | +| Local gate before the round | workspace `--lib --bins` exit 0 | ALL_GREEN | ALL_GREEN | ALL_GREEN | + +- **Round 1.** The five P0s: an accepted team invitation collapsed every member's open channel; a host + could not get admitted people into channels; every Copy failed (the renderer permission allowlist + denied clipboard writes); the Join dialog's Institution field kept only the first letter; focus was + invisible under Increase Contrast and forced colours.

So a chat revoked from the CLI or another window can still + have its stored transcript cut by Edit in place, if this window has not re-read its grant yet. The + turn itself is still refused before anything reaches the model. `/diverge` is not held in the + renderer; the daemon's `create_derived_session` refuses to copy a Crew chat. +- **D-1's detection.** The daemon notices D-1 only when it next asks the broker. An idle chat's grant + reads `expired: false` until then. The renderer recognizes the refusal by matching its text. +- **F5's dates.** F5 dates only revokes this window saw confirmed; NEW-3 below is the live case. +- **`replaced_grants` gaps.** The desktop does not list `replaced_grants` yet; the CLI and the route + do. A replaced grant with no recorded expiry is dropped at confirmation, so a task ledger that has + not re-read in between keeps its "didn't confirm" note. +- **O-1's census.** It matches literal paths only.

After the network was restored, the daemon re-dialled and confirmed with no click: journal `run.revoke` at seq 19, 21 and 37. `grants list` moved from `unconfirmed`/`false` to `confirmed`/`true`, and the pane read "Confirmed. The workspace has stopped this chat's access too." | +| NEW-1 | **PASS** | A failed Connect during an outage read "Can't reach 184.32.228.165." After the daemon's own re-dial the view showed Connected with no click.

The CLI said the same, and no file was written. Crew closes the channel as soon as access ends, so no file card was left to click | +| O-1 (denial matrix) | **PASS** | `location.hash` was sampled every second in both apps for about 45 minutes (2,711 and 2,710 samples).

Its deadline supervisor, `supervisor.sh`, runs `cleanup.py` at the deadline: check that it is running (the state file records its PID) before you rely on it. + 3. If this Mac is on the full-tunnel VPN, authorize its egress /32 on the new security group (never `0.0.0.0/0`), and start every daemon, app and SSH process outside the Bash tool's sandbox. + 4. Create profiles and start daemons and apps with `crew_qa.py init …`, `daemon-start … --art ` and `app-start … --dev-auto-confirm-share` (omit the flag to test the real share confirmation); check each app reaches only its own daemon with `attach_check.py` and `renderer_check.js`; pause every profile's built-in `daily-meditation` schedule with `daemon_schedule.py pause daily-meditation`. + 5. Drive the CLI through `crew_cli.py -- …`, which pipes the approval key on stdin and scrubs secrets from its logs. `tools/final/install_broker.sh` and `restart_brokers.sh` upgrade brokers in place as their owners. + 6. The workflow scripts that ran the campaign are `/private/tmp/crew-ui-redesign/tools/live-qa-round1.js`…`live-qa-round4.js` and `closeout.js`. +- **Credentials.** Use only the working Versa key in `/private/tmp/crew-mac-profiles-4a2e190b.bKx8iO/alice/native-home19/biorouter/config/secrets.yaml`, copied without printing; the key in `~/.config/biorouter` is stale, and the user's own configuration must not be modified. +- **Model.** Every agent turn uses private Versa `versa_azure` / `gpt-5.5-2026-04-24`; no local models. + +## Campaign record since resuming on 2026-09-23 + +Work resumed on 2026-09-23 (US Pacific evening; UTC 2026-09-24) in a Claude Code session operating in this same worktree and branch, at the user's explicit request. The pause boundary and "do not resume" instructions below are historical: they record the state at pause and remain the evidence baseline, but no longer stop work. Receipts, evidence scopes, limits and cautions below stay in force unless this section says otherwise. + +Standing user instructions for the resumed work: + +1. Finish the remaining implementation, execution and testing comprehensively. Resume priorities 1–5 below remain in force: e11 artifacts and hosted checks, provider-resume/observer replay, the ignored live fairness case with a disposable ACL fixture, the ordinary-GUI revoke control, required self-test assertions and fourth-profile CLI corroboration. +2. Testing is fully autonomous, with no user approvals or interaction. Use disposable AWS fixtures containing only synthetic data. The user explicitly authorizes creating, using and cleaning up those fixtures, installing verified binaries and synthetic data on them, and the dev-only automatic approval stdin for isolated synthetic QA. The previously blocked fourth-profile CLI corroboration is therefore authorized, for the synthetic fixture only. Production human proof, SSH/MFA gates and privacy gates are unchanged; authorization to test weakens no gate. +3. All live agent QA uses private Versa `versa_azure` / `gpt-5.5-2026-04-24`. No local Qwen, Ollama or llama models. +4. New scope, Crew GUI redesign: clean, minimal, elegant and Slack-like, consistent with BioRouter's design system (`design.md`, theme tokens) and the rest of the chat UI. Layered navigation (dropdown menus rather than flat rows of equal-weight buttons); progressive disclosure (only required fields visible, optional and advanced options behind an Advanced disclosure); obvious affordances (dropdowns look like dropdowns, lists like lists, anything to share in a code-block-style box with one-click Copy); far less explanatory text and disclaimer copy, keeping only what has immediate consequences; good animation and transitions; usable by a complete novice. Fresh agents driving the real app act as novice UI/UX critics, and the design iterates until they succeed unaided. +5. New scope, human-readable identity and naming: people appear by display name or at least `@username` (unique per SSH server), never by long machine IDs (UUIDs, hex keys, principal IDs). Teams get unique, memorable names per workspace instead of machine strings, and setup uses these names (for example, invite `@bob` instead of copying an opaque token). Machine IDs remain internal, optionally behind a Copy ID or details affordance. Any protocol change must preserve kernel-derived identity, UID-recycling protections and every existing security property, with adversarial regressions. +6. Keep the [implementation plan](implementation-plan.md) and this handoff updated in real time whenever a decision changes execution, so all agents stay current. + +Requirements 4 and 5 are recorded as acceptance requirements in [plan §16](implementation-plan.md#16-resumed-scope-gui-redesign-and-human-readable-identity-2026-09-23). Their designs were accepted on 2026-09-23: the [UI redesign specification](ui-redesign-spec.md) and the [naming design](naming-design.md). Plan §16 also lists the 28 [work packages and their order](implementation-plan.md#work-packages-and-order): 27 implementation packages and LIVE-QA, the acceptance package. SCOPE-BIND, added on 2026-09-24, made it 28. + +**Where the campaign stood on 2026-09-24 (~14:00Z, updated through round 2), as written then.** Implementation is complete. All 27 implementation packages have reported and passed independent review. An [integrate-verify pass](#integrate-verify-pass-2026-09-24) then ran the whole gate on the integrated tree and triaged defects D1–D16 and one gate failure, GATE-1. Its fix groups committed fixes for them, and its final gate was green at `1ec9eb8b`. That pass's gate filtered the `biorouter` library tests, and one test it skipped fails (open finding 5). LIVE-QA, the 28th package, is under way. Round 2 (gates green at `5b079379`): 0 P0, 16 P1, 62 P2; 49 round-1 findings verified fixed; 49 novice tasks, 28 unaided, 14 with friction, 7 failed; Frank 12/13 steps (10 unaided); security boundaries held, including direct add; report `/private/tmp/crew-ui-redesign/live/reports/TRIAGE-r2.md`. Fixture deadline extended to 2026-09-25T14:25:14Z, supervisor restarted (PID 710); round 3 is in progress. Round 1 ran 38 novice tasks (15 unaided, 17 with friction, 1 "no", 5 failed; 5 P0, 23 P1, 41 P2; security boundaries held; report `/private/tmp/crew-ui-redesign/live/reports/TRIAGE-r1.md`). + +Rounds 3 and 4, the `join-by-name` default and the close-out are entries in the [decisions log](#decisions-log). + +### Coordination structure + +A Claude Code coordinator orchestrates subagent workflows. For the resumed session this replaces the Astra/Luna lane assignment listed under the pause boundary below; those lane names still identify who produced the historical evidence. Roles: + +- **Research and design:** recon and written specifications; no product edits. +- **Implementation:** product source changes under explicit, non-overlapping file ownership. +- **Review:** independent adversarial review of each product diff, with identity, authorization and privacy changes reviewed before acceptance. +- **Test execution and GUI critics:** builds, test runs, fixture operation and real-app driving, including fresh novice critics for the redesign. +- **Docs keeper:** keeps this handoff and the plan current; the coordinator commits. + +### Implementation progress + +One row per [plan §16](implementation-plan.md#work-packages-and-order) package once it reports. A row states what the package reported and what its review found; it is not live acceptance. + +| Package | Status | Commits | Result | +|---|---|---|---| +| UI-IDENTITY | Done; review pass, no blockers | `0c5fdc71`, `29de246f`, `23978c49` | `crew/identity/`: PersonName (header, inline, authority, chip, joiner), personLabel strings from one `personLayout()`, usePeopleDirectory, nameKey fallback, display-name sanitizer, institution and object names. 109 tests pass; typecheck, ESLint, `lint:check` and Prettier on identity files pass. | +| UI-API | Done; review pass, no blockers | `ee34c3da`, `156a2640` | Crew wire types enriched; `crew/api/` grants, names, join, errors and parse helpers with tests. Revoke resolves only on a confirmed revoke. Prettier gate on `src/components/crew/**` not yet passable (pre-existing unformatted files outside the package). | +| UI-PRIM | Done; review pass, no blockers | `1c068364`, `49c7eec3`, `7181a809` | `ui/` CopyField, StatusDot, Disclosure, Avatar (CSS in `main.css`, tokens only, reduced-motion rules); eight Crew icons; `crew/crew-app.css` layout stylesheet and `crewCss.sourceGuard.test.ts`. A throwaway Vite+Tailwind browser page found and fixed a 0px cover-mode pane and a ⌘C that copied display text; push measured at 806px (pane 360, channel 446), cover at 758px. Reduced motion pinned at source only, not checked in a browser. Crew-wide Prettier fails on 10 files owned by UI0, UI-INTEGRATE and `crewApi.observation.test.ts`, none UI-PRIM's; `annotationChannel.test.ts` fails on UI-IDENTITY's in-flight `displayText.ts` second drop set. | +| UI0 | Done; review pass, no blockers | `1b324a7d`, `556d5480`, `eff65ab7`, `78f8f356` | Logic moved from `CrewView.tsx` into `crew/state/` (`useCrewController`, `CrewControllerContext`, connections, observation loop in original effect order, actions, send, run start, failure classifiers, derived status/screen); markup moved unchanged to `crew/legacy/LegacyCrewLayout.tsx` (mechanical JSX diff: handler rewiring only, no string changes); `CrewView` is a thin root taking `layout` and `controllerOptions`. CVT, CAT, CFT and crewApi/crewTransfers tests pass unedited; 142 new state tests. Review fix: a saved-disconnected connection with an observer error now reads `offline`, not `updates-paused` (four tests fail against the old logic). | +| CLI-OUT | Done; review pass, no blockers | `1931fc1f`, `e1c81e14` | `commands/crew/output.rs`: per-type text formatters (snapshot, members, teams, channels, invitations, connections, messages, tasks, grants, privacy, transfers, mutations) naming people `"Name" (@user)`, channels `#name`, IDs hidden; names from a `Directory` built from the printed value. JSON/stream-JSON unchanged. `daemon_refusal` now prints the daemon's exact sentence via `terminal_safe()` (3 regression tests). Until CLI-CMD passes `Directory::from_snapshot` (or S1a sends `people`), authors, owners and inviters print `Unknown member`. | +| CLI-STREAM | Done; review pass, no blockers | `96b751b3` | `stream_shell_output` strips only the line ending (whitespace-only lines still dropped); each `shell_output` notification carries a per-command `seq`; CLI `session/shell_output_order.rs` (`ShellOutputOrder`, keyed by tool request id) reorders, releasing on the call's response, turn end, Ctrl-C and stream error. Server test over a captured transport (fails with `.trim()` restored), 13 buffer tests incl. the e11 `crew --help` replay, 4 wiring tests. Strict clippy on the two crates only; full `clippy-lint.sh` not run. Open: `mcp_client.rs` `try_send` on a 16-slot channel drops lines under a burst; concurrent shell calls on one unpooled client probably see each other's lines (read, not measured); pooled clients get no live output; stream-json carries no `seq`. | +| N-LIB | Done; review pass, no blockers | `189c071d` | `biorouter-crew`: `names.rs` (name keys, `names_collide`, display/team/channel/workspace validators and sanitizers, `NameError` code `name_invalid` that never echoes input), Unicode 17.0.0 `default_ignorable.rs`, `invitation.rs` (`brcrew1:` codec with 4 KiB/64 KiB caps and legacy status JSON, `InvitationError` `invitation_*`, device codes with constant-time `device_code_matches`, key fingerprints), `Workspace.name`, `PendingJoin`, `hello_v1_payload`, `HelloV2::signing_payload`. New deps `unicode-security =0.1.2`, `unicode-script =0.5.8` (supply chain checked); features `test-seams`, `join-by-name` off by default. `tests/name_rules_contract.rs` 18 tests pass on macOS and Linux; clippy and fmt pass. Extra file: `broker.rs` got `name: None` (~line 516). Open: Linux broker writer-node tests need a mounted `/etc/machine-id` (none in `rust:1.92-bullseye`); `cargo check -p biorouter` not run separately (workspace clippy compiled it). | +| BE-SSH-FAIL | Done; review pass, no blockers after fix | `fca564bb`, `099cf347` | `crew/transport.rs`: ssh stderr drained for the whole session (first 8 KiB kept, task aborted on drop); fatal failures return `SshFailure {kind, code, status, description, detail}` in `anyhow::Error` with `api_code()` (`crew_ssh_auth_required`, `crew_ssh_host_key_unknown`, `crew_ssh_host_key_changed`, `crew_ssh_unreachable`, `crew_bridge_missing`, `crew_ssh_failed`). `Display` byte-identical to the old message; hand-written `Debug` shows only the detail length. SSH-level rules read stderr only on exit 255 (review fix `099cf347`: the bridge's `Error: ` exit 1 had matched unreachable/auth); 126/127 or remote not-found text is BridgeMissing; a live child is `Other`. Detail sanitized, fingerprints first, ≤ 2 KiB. 25 transport tests pass on six runs; mutation checks on the drain and the 255 gate made the tests fail. Only command change: `stderr(Stdio::piped())`. | +| UI-ACCESS | Done; review pass, no blockers | `38a02347`, `ec7b9cf1`, `854a3346`, `903a5814` | `crew/access/`: `useCrewGrants` (fetch on open/refetch/grants-changed event, never polls; shared per Crew view), fail-closed `revokeGrant` (503 or unconfirmed 200 → "Stopped on this device", else "Not revoked" with the daemon's words; never throws), pure `accessRows`, ChatConnectNote, ChatAccessPane (consent, Allow, "Connected." without navigating, inline revoke confirm, Grant again), AccessList/AccessTab/WorkspaceAgentAccess, AgentsSection, `useAgentAccessCount`. Ordinary chat: `ChatCrewAccessBar` in BaseChat's composer slot holds the composer via `submissionBlocked` after revoke/expiry (one `expires_at` timer, never held on a failed lookup); extension menu's Crew row stays on while a grant is active. 75 tests in 7 files. Open: UI-INTEGRATE wiring; CrewView tests must wait out "Checking this chat’s access…"; depends on SCOPE-BIND pruning stale scopes from GET …/grants; crew-wide Prettier flags 7 files of other packages; `annotationChannel.test.ts` fails on UI-IDENTITY's `displayText.ts`. | +| UI-CHANNEL | Done; review pass, no blockers after fix | `931e951f`, `15b196ab`, `827ef806`, `cffa32c7`, `150679e8` | `crew/channel/` ChannelHeader, ChannelMenu, ConnectionBar; `crew/pane/` DetailsPane (non-modal, follows `ui.pane`), About/Members tabs, AgentTaskPane, CrewModelPicker, `newestTask.ts`. 107 tests in 9 files plus the CSS guard; crew+ui+copy/dialog guards 1131 tests, typecheck, crew ESLint `--max-warnings 0`, `lint:check` clean; checked in Chrome via a temporary Vite harness (push 1048px, cover 760px, dark). Review fix: Show task in channel goes through `onShowTask` instead of a DOM probe. Not mounted until UI-INTEGRATE. | +| UI-DIALOGS | Done; review pass, no blockers | `2a86331b`, `fc23a666`, `9c7bcfcc`, `836b69b0`, `cb08c175` | `crew/dialogs/`: `CrewDialogs` host on `ModalShell` (keyed per intent, first-field focus), Connection settings `
    ` (native validation, Private-only institution, auto-open Advanced, typed Private→Public confirm), Workspace settings (General · People · Privacy · Agent access slot), Invite, Let in (`DeviceCodeInput`), Create team/channel, Add people (`PersonPicker`), Transfer, Rename, Edit profile, Keys and security, Share a server path, and `confirmations.tsx`. Additive changes to `ConfirmationModal` (children slot) and `DangerousConfirmDialog` (`onPhraseChange`). Package gates pass; checked in a browser via a temporary Vite harness. Full-suite run: one UI-CHANNEL pane test failed once and passes alone; crew-wide Prettier fails only on 2 files of other packages. | +| UI-SHELL | Done; review pass, no blockers after two fixes | `120f4ab0`, `71fe8789`, `b9816364`, `543bf5c3`, `d7d843cd` | `crew/sidebar/`: CrewSidebar (`
