+# agentOS -## Why agentOS +agentOS is a lightweight Linux-compatible VM runtime for isolated filesystem, +process, terminal, language, and networking workloads. -Powered by WebAssembly and V8 isolates, the same technology powering Chrome and -Cloudflare Workers. Linux with POSIX files, processes, and networking. +It ships in two forms: -- **Library, not extra infrastructure.** Install agentOS from npm and run it inside the backend process you already operate. -- **WebAssembly + V8, not a microVM.** V8 isolates run JavaScript while WebAssembly contains compiled tools inside the same compact runtime. -- **Direct function calls, not extra APIs.** Connect agents to your application with ordinary JavaScript calls instead of another network service. -- **Scoped access, not exposed credentials.** Bind trusted host functions without ever giving the agent your raw secrets. -- **One process, not a VM per agent.** Many isolated agent operating systems share one compact runtime instead of duplicating a full microVM stack. -- **Runs anywhere, no nested virtualization.** Deploy on standard Linux infrastructure without a hypervisor or nested virtualization. +- a fixed Rust Rivet actor named `agentOS`, accessed through a generated + TypeScript contract; +- `@rivet-dev/agentos`, the embedded TypeScript API for trusted Node.js + applications. -## Benchmarks +The actor is a thin lifecycle and transport wrapper around Core. It does not +contain a configurable TypeScript actor implementation. -| Metric | agentOS | Sandbox baseline | Difference | -|---|---|---|---| -| Cold start, p50 | 4.8 ms | 440 ms | 92× faster | -| Cold start, p95 | 5.6 ms | 950 ms | 170× faster | -| Cold start, p99 | 6.1 ms | 3,150 ms | 516× faster | -| Memory, shell workload | ~22 MB | 1,024 MB | 47× less | -| Cost per execution-second, shell workload | $0.000000073 | $0.000018 | 254× cheaper | - -See the [benchmark details](https://rivet.dev/agentos#bench-cold-start) for -methodology, or [Performance](https://rivet.dev/agentos/docs/performance) to run -the benchmarks yourself. - -## Quickstart - -

- - - Library: agentOS runs as a VM inside your backend. Or hosted: your backend and frontend call an agentOS VM over HTTP. - -

- -
- -| | Library | Hosted | -|---|---|---| -| **Runs** | Inside your process | Durable instance on Rivet Cloud or self-hosted | -| **Lifecycle** | Runs until `dispose()` or process exit | Sleeps when idle unless a process is running | -| **Clients** | Your backend | Your backend, or browsers with a scoped JWT | -| **Preview URLs** | None | Expiring preview URLs | - -
- -### Library - -**Step 1: Install the library** +## Hosted actor ```bash -npm install @rivet-dev/agentos-core +npm install @rivet-dev/agentos rivetkit ``` -**Step 2: Create a VM and use it** - ```ts -import { AgentOs } from "@rivet-dev/agentos-core"; - -// Boots a VM inside this process. It runs until dispose() or process exit. -const vm = await AgentOs.create(); +import { createAgentOsClient } from "@rivet-dev/agentos"; -try { - // Bash - const result = await vm.process.exec("echo hello && ls /home/agentos", { - output: { capture: "all" }, - }); - console.log(result.stdout); +const client = createAgentOsClient(); +const vm = client.agentOS.getOrCreate(["workspaces", "demo"], { + createWithInput: { + config: { + filesystem: { + root: { type: "durable", namespace: "root" }, + }, + }, + }, +}); - // Filesystem - await vm.filesystem.writeFile("/home/agentos/hello.txt", "Hello, world!"); - const file = await vm.filesystem.readFile("/home/agentos/hello.txt"); +await vm.filesystem.writeFile({ + path: "/home/agentos/hello.txt", + content: "hello\n", +}); - // JavaScript - await vm.javascript.execute("console.log(1 + 2)"); +const result = await vm.process.run({ + command: "cat", + args: ["/home/agentos/hello.txt"], + options: { env: {}, captureStdio: true }, +}); - // Python - const answer = await vm.python.evaluate("21 * 2"); -} finally { - await vm.dispose(); -} +console.log(result.stdout); ``` -**Step 3: Configure the VM** - -The filesystem is in memory by default. Pass options to `AgentOs.create()` to -persist it, attach other filesystems, and lock the VM down. +Creation config is used only when the actor is first created.

- - - The library or the HTTP API connects to the agentOS sidecar process over stdio and a Unix socket. Its trusted kernel owns processes, the filesystem, networking, and permissions. Untrusted guest code runs in V8 isolates and WebAssembly and reaches the kernel only through syscalls. - -

- -The agentOS sidecar is a Rust process that runs separately from your -application's process. The kernel and all guest code live in the sidecar, so -untrusted code and its memory never enter your process. The library, -`@rivet-dev/agentos-core`, starts and owns the sidecar from your backend and -talks to it over stdio and a Unix socket. When hosted, you control the same -sidecar over the HTTP API. - -The sidecar's trusted kernel owns the process table, the virtual filesystem and -its mounts, the socket table, and permissions and resource limits. - -Untrusted guest code also runs inside the sidecar. JavaScript and TypeScript run -in V8 isolates, and the shell, coreutils, and Python run as WebAssembly. - -The entire kernel is virtualized. Every file, process, and network operation is -a syscall into the kernel, so by default guest code can't reach host files, -processes, environment variables, or the network. You opt in to host access -with mounts, host functions, and network permissions. See -[Architecture](https://rivet.dev/agentos/docs/architecture) for details. - -## API Overview - -Library methods live under `vm.`. Hosted actions live under -`vm.v1.`, or `POST /gateway/{vm_id}/action/v1..` over -HTTP.

Sends an ACP **`get_session_state`** request as a wire `ExtEnvelope`. +4. The frame is routed `BrowserAcpExtension → AcpCore` (the host-free engine + shared verbatim with the native sidecar), which returns a real ACP response. + +This exercises the full converged path in the browser: wire decode → auth → +extension dispatch → host-free ACP core → wire encode, with no host I/O and no +guest-side permission evaluation (the wasm kernel enforces). + +## Why this path and not a full `pi` session (yet) + +The demo round-trips an ACP request that needs no agent process. Running a full +agent such as **`pi`** end-to-end *in the browser* additionally requires two +pieces that are out of scope for the current browser-convergence milestone: + +- **Browser agent-process executor (a deep architectural blocker, not a wiring).** + The converged sidecar + the synchronous host-free `AcpCore` run on the **main + thread**; `pushFrame` is synchronous and `create_session` must block-wait for the + agent's stdout. But an agent runs in a **Worker** (async), and the main thread + cannot block-wait for it: `postMessage` output can't arrive while `pushFrame` is + blocking, and `Atomics.wait` is **forbidden on the main thread** in browsers. So + the converged executor's `startExecution`/`writeExecutionStdin`/ + `pollExecutionEvent` callbacks are deliberate no-ops. Resolving it requires either + running the sidecar+`AcpCore` **inside a worker** (so `Atomics.wait` is legal) or + making the ACP orchestration **asynchronous/resumable** — both substantial + redesigns. The host-free `AcpCore` + `BrowserAcpHost` seam are in place + (`archive/browser/crates/sidecar-core`, `archive/browser/crates/sidecar-browser/src/acp_host.rs`) + and proven end-to-end natively; only the in-browser agent-process *host* is gated + on this redesign. +- **Host network egress.** `pi` calls the Anthropic API. Browser convergence is + loopback-only by design; host egress is out of scope. So `pi`'s API calls + cannot leave the browser sandbox as currently scoped, independent of the + executor. + +The native side already proves the engine end-to-end: `AcpCore` drives a real +agent process through a full `initialize` + `session/new` handshake in +`archive/browser/crates/sidecar-core/tests/real_agent_round_trip.rs` (native `AcpHost` +over `std::process`). The browser demo proves the same engine answers real ACP +wire requests in Chromium.

    + What this proves: the converged agentos-sidecar-browser wasm + module decodes a BARE wire frame, runs the authenticate handshake, routes + an ACP get_session_state request through + BrowserAcpExtension → AcpCore (the host-free engine shared + with the native sidecar), and returns a real ACP response — all in-page, + with the wasm kernel as the sole enforcement point. +

    +

    + Running a full agent (e.g. pi) end-to-end in the browser + additionally requires the browser agent-process executor (worker stdio + wiring) and host network egress; both are tracked as out-of-scope for the + current browser-convergence milestone. See DEMO.md. +

Do NOT reintroduce `openat2`, an `O_PATH` *metadata/leaf* anchor, `/proc/self/fd` re-opens, or a macOS-specific path — the confinement boundary is the single universal `confine` module (see it and `crates/native-sidecar/CLAUDE.md` for why `openat2` was removed and why the non-root read constraint drives these choices). An `O_PATH` *directory traversal* anchor for search-only intermediate dirs (`confine::open_dir_anchor`, Linux-only, `EACCES` fallback) is allowed and is not a metadata anchor. +- **Explicit host mappings remain confined mount/plugin resources, not filesystem mirrors.** Metadata and symlink operations must resolve beneath the configured mapping root and enforce kernel process policy without creating or synchronizing a duplicate kernel entry. Ordinary guest paths never fall back to ambient host filesystem operations. +- **`host_dir` metadata ops must resolve beneath the mount root, reject symlink leaves, and NOT require read on the target (non-root sidecar).** In `crates/vm/src/plugins/host_dir.rs`: `chown`/`utimes` resolve the parent via `split_parent`, `reject_symlink_leaf` (an `fstatat` `lstat` through the anchored parent fd → `EPERM` on a symlink), then mutate with `fchownat`/`utimensat(.., AT_SYMLINK_NOFOLLOW)` against `(parent_fd, leaf_name)` — no leaf open, so no read requirement, and `AT_SYMLINK_NOFOLLOW` closes the check→mutate swap race. `stat`/`exists` use `confine::resolve_parent_beneath` + `fstatat`. `chmod` is the deliberate exception: `fchmodat` has no `AT_SYMLINK_NOFOLLOW`, so it keeps `open_metadata_beneath` (leaf `O_RDONLY | O_NOFOLLOW`) + `fchmod` for TOCTOU safety, accepting the read requirement.

longer waits should return the currently observed socket state after the ceiling expires instead of monopolizing dispose/shutdown or unrelated VM work. @@ -111,18 +111,18 @@ These are hard rules with no exceptions: - **Process-event handlers must fail closed on stale VM/process state.** In `crates/sidecar/src/execution.rs` and `crates/sidecar/src/service.rs`, any VM/process lookup reached from queued execution events or JS sync-RPC dispatch should log through `log_stale_process_event(...)` and return cleanly instead of using `expect(...)`, because teardown can win after an event is queued but before it is drained. - **Queued stale-process race regressions should use the process-event channel, not direct handler calls.** In `crates/sidecar/tests/service.rs`, keep the sequential smoke path that queues envelopes then disposes, and drive real dispose-vs-send races by cloning `process_event_sender`, synchronizing sender/dispose with a `Barrier`, then draining with `poll_event_blocking(..., Duration::ZERO)` and asserting the bridge captured a `log_stale_process_event(...)` message. - **Shared sidecar test helpers should opt into `PermissionsPolicy::allow_all()` unless a test is explicitly about permissions.** In `crates/sidecar/tests/support/mod.rs` and similar harnesses, `permissions: None` now means default-deny, so generic runtime/filesystem fixtures need explicit allow-all creation to avoid unrelated regressions under scoped Cargo filters like `filesystem`. -- **When extracting large sidecar test modules out of `src/`, keep the tests in `crates/sidecar/tests/*.rs` by wrapping `include!("../src/...")` in a same-named module and nesting the moved assertions under `mod tests`.** This preserves the original `use super::*` access to private helpers, and service-style harnesses also need crate-root re-exports for items that sibling modules import via `crate::{DispatchResult, NativeSidecar, SidecarError}`. +- **When extracting large sidecar test modules out of `src/`, keep the tests in `crates/sidecar/tests/*.rs` by wrapping `include!("../src/...")` in a same-named module and nesting the moved assertions under `mod tests`.** This preserves the original `use super::*` access to private helpers, and service-style harnesses also need crate-root re-exports for items that sibling modules import via `crate::{DispatchResult, VmManager, VmError}`. - **If a shared `src/` module carries helper code that only those included test harnesses use, gate the helper types/functions and their imports with `#[cfg(test)]`.** That keeps focused library builds like `cargo test -p agentos-sidecar --test protocol` warning-free without moving the test scaffold back into production code paths. -- **Sidecar integration tests surface handler failures as `Rejected(...)` responses, not transport-level `Err`s.** When `dispatch_blocking(...)` reaches a real request handler and that handler returns `SidecarError`, assert on `ResponsePayload::Rejected { code, message }`;

Inline `#[cfg(test)]` is only acceptable for trivial unit tests of private helper functions. - Some V8-backed Rust integration binaries still trip teardown/init crashes or SIGSEGVs when multiple libtest cases share the same binary. For those targets, keep coverage in one top-level suite test per `crates/*/tests/*.rs` file until the shared-runtime teardown bug is fixed. - Node builtin compatibility regressions should usually land in `crates/sidecar/tests/builtin_conformance.rs`: that harness runs the same probe script under host Node and guest V8 and asserts exact JSON parity, which is the fastest way to catch module-shape mismatches like `require("events")`. - Keep `crates/sidecar/tests/builtin_conformance.rs` as one top-level `builtin_conformance_cases` test that forks per-case subprocesses via `AGENT_OS_BUILTIN_CONFORMANCE_CASE`; that preserves the exact `cargo test -p agentos-sidecar --test builtin_conformance` acceptance surface while isolating V8-backed cases from each other. -- For sidecar POSIX conformance coverage, keep `/proc`, `/dev`, `waitpid`, and process-group assertions as direct `agentos_kernel` / `ProcessTable` tests where possible, and reserve the sidecar/V8 harness for guest-observable behaviors such as signal delivery that require the full runtime bridge. +- For sidecar POSIX conformance coverage, keep `/proc`, `/dev`, `waitpid`, and process-group assertions as direct `agentos_vm_kernel` / `ProcessTable` tests where possible, and reserve the sidecar/V8 harness for guest-observable behaviors such as signal delivery that require the full runtime bridge. - Run scoped tests: `cargo test -p agentos-sidecar -- test_name_filter` or `cargo test -p agentos-sidecar --lib` (lib unit tests only, skip integration tests). - Never run bare `cargo test -p agentos-sidecar` without a filter -- integration tests spawn real processes and can hang. - In `crates/sidecar/tests/service.rs`, keep the broad V8-backed integration coverage under a single top-level test because multiple libtest cases in that binary still trip V8 teardown crashes.

Module loading is fully intercepted — guest code never touches real host APIs. The previous JavaScript kernel packages had full kernel-backed polyfills for all builtins. - -**Current state (⚠️ STILL INCOMPLETE -- see `~/.agents/todo/node-isolation-gaps.md`):** - -Guest JavaScript entrypoints in `javascript.rs` now run only through the shared V8 runtime. The remaining gaps are polyfill completeness and builtin isolation parity: some builtins still need deeper kernel-backed implementations or broader conformance coverage, but restoring a host-Node guest execution fallback is not allowed. - -- Keep any real-host Node helpers isolated to clearly host-only modules used by benchmarks or import-cache tests. Guest JS/WASM/Python runtime code should depend only on neutral shared helpers (for example signal metadata or path resolution), not on files that also own host launch behavior. -- Guest-side WebAssembly inside the V8 isolate must stay enabled on both fresh isolates and snapshot restores. Real npm packages rely on `WebAssembly.Module`, `WebAssembly.Instance`, and `WebAssembly.instantiate*`, and allowing those APIs does not violate the kernel-isolation boundary because compilation stays inside the isolate. Do not reintroduce an embedder callback that blocks WASM; rely on V8's own implementation limits instead. - -**Recovery reference:** The complete working polyfill + V8 isolate code from the original JavaScript runtime packages has been recovered to `~/.agents/recovery/agentos/`. Key files to port: -- `nodejs/src/bridge/fs.ts` (3,974 lines) -- full kernel-backed `fs`/`fs/promises` polyfill -- `nodejs/src/bridge/network.ts` (11,149 lines) -- full `net`/`dgram`/`dns` polyfill via kernel socket table -- `nodejs/src/bridge/child-process.ts` (1,058 lines) -- `child_process` polyfill via kernel process table -- `nodejs/src/bridge/process.ts` (2,251 lines) -- virtualized `process` global (env, cwd, pid, signals) -- `nodejs/src/bridge/polyfills.ts` (914 lines) -- polyfill registration and module hijacking -- `nodejs/src/bridge-handlers.ts` (6,405 lines) -- host-side bridge handlers for all kernel syscalls -- `nodejs/src/execution-driver.ts` (1,693 lines) -- V8 isolate session lifecycle + bridge setup -- `kernel/` -- the JS kernel (VFS, process table, socket table, PTY, pipes) -- `v8/` -- V8 runtime process manager, IPC binary protocol - -The original source repo is at `/home/nathan/agentos-1/` (tagged `v0.2.1`). - -**Prior art -- the original JS kernel had full polyfills:** - -Before the Rust sidecar (commit `5a43882`), the JavaScript kernel and `packages/posix/` had complete kernel-backed polyfills for all builtins. The pattern was: -- **Kernel socket table** -- `kernel.socketTable.create/connect/send/recv` managed all TCP/UDP. Loopback stayed in-kernel; external connections went through a `HostNetworkAdapter`. -- **Kernel VFS** -- All `fs` operations routed through the kernel VFS via syscall RPC. -- **Kernel process table** -- `child_process.spawn` routed through `kernel.spawn()`. -- **SharedArrayBuffer RPC** -- Synchronous syscalls from worker threads used `Atomics.wait` + shared memory buffers (same pattern the Pyodide VFS bridge uses today). -- **Module hijacking** -- `require('net')` returned the kernel-backed socket implementation, not real `node:net`. - -The Rust sidecar kernel already has the VFS, process table, pipe manager, PTY manager, and permission system. What's missing is porting the **polyfill layer**. This is a port of proven patterns, not a greenfield design. - -### Current reality vs required state - -| Builtin | Required | Current | Gap | -|---------|----------|---------|-----| -| `fs` / `fs/promises` | Kernel VFS polyfill | Path-translating wrapper over real `node:fs` | Port: route through kernel VFS via RPC | -| `child_process` | Kernel process table polyfill | Path-translating wrapper over real `node:child_process` | Port: route through kernel process table | -| `net` | Kernel socket table polyfill | **No wrapper -- falls through to real `node:net`** | Port: kernel socket table polyfill | -| `dgram` | Kernel socket table polyfill | **No wrapper -- falls through to real `node:dgram`** | Port: kernel socket table polyfill | -| `dns` | Kernel DNS resolver polyfill | **No wrapper -- falls through to real `node:dns`** | Port: kernel DNS resolver polyfill | -| `http` / `https` / `http2` | Built on kernel `net` polyfill | **No wrapper -- falls through to real module** | Port: builds on `net` polyfill | -| `tls` | Kernel TLS polyfill | Guest-owned polyfill in `node_import_cache.rs` wraps the existing guest `net` transport with host TLS state | Keep client/server entrypoints on guest sockets and avoid direct host `node:tls` listeners/connections | -| `os` | Kernel-provided values | Guest-owned polyfill in `node_import_cache.rs` virtualizes hostname, CPU, memory, loopback networking, home, and user info | Keep future `os` additions aligned with VM defaults | -| `vm` | Guest-owned compatibility shim for package loading | Guest-owned compatibility builtin for `Script`, `createContext`, `isContext`, `runInNewContext`, `runInThisContext` | Keep it limited to the compatibility surface; do not fall through to host `node:vm` | -| `worker_threads` | Guest-owned compatibility shim for package loading | Guest-owned compatibility builtin exposing `isMainThread` plus inert ports; `Worker` construction stays unavailable | Keep it importable for feature detection, but never spawn real threads | -| `inspector` | Must be denied | **No wrapper -- falls through to real module** | Must stay denied | -| `v8` | Guest-owned compatibility shim for package loading | Guest-owned compatibility builtin for safe inspection/serialization helpers | Keep it limited to the compatibility surface; do not fall through to host `node:v8` | - -### Loader interception (`node_import_cache.rs`) - -The host-support ESM loader hook (`loader.mjs`) is generated from a Rust string template. The obsolete native-Node guest `runner.mjs` was removed when JavaScript execution moved to embedded V8; do not restore a second networking or CJS pump there. Loader imports are intercepted as follows: -1. `resolveBuiltinAsset()` -- checks `BUILTIN_ASSETS` list. Redirects to a kernel-backed polyfill file. -2. `resolveDeniedBuiltin()` -- checks `DENIED_BUILTINS` set. Redirects to a stub that throws `ERR_ACCESS_DENIED`. A builtin is in `DENIED_BUILTINS` only if it is NOT in `ALLOWED_BUILTINS`. -3. **Fall through to `nextResolve()`** -- Node.js default resolution. Returns the real host module. **This must never happen for any builtin that guest code can import.** - -`AGENTOS_ALLOWED_NODE_BUILTINS` (JSON string array env var) controls which builtins the host-node loader removes from the deny list. The default list `DEFAULT_ALLOWED_NODE_BUILTINS` lives in `crates/sidecar/src/execution.rs`. Note the live shared-V8 path enforces builtin denial at the Rust resolver (`LocalBridgeState::resolve_module` in `crates/execution/src/javascript.rs`, gated by `AGENTOS_JS_BUILTIN_ALLOWLIST`), not via this env var — see the `jsRuntime` config. - -- CommonJS `require` wrappers in `packages/build-tools/bridge-src/` must expose Node-compatible metadata on every per-module require function, not just on `Module.createRequire(...)`. Real packages call `delete require.cache[__filename]`, inspect `require.extensions`, and expect `require.main` to exist while running inside nested CommonJS modules. -- The builtin `buffer` module wrapper must re-export `Blob` and `File` alongside `Buffer` constants. Next.js bundles `undici` through `require("buffer")`, and missing `buffer.Blob` / `buffer.File` breaks `fetch` support even when global `Blob` / `File` exist. -- Keep the custom `events.EventEmitter` implementation function-constructible rather than a strict ES class. Legacy npm packages still use `util.inherits(..., EventEmitter)` plus `EventEmitter.call(this)`, and that pattern must stay compatible. -- Local bridge module resolution must accept `file:` specifiers by converting them back to guest paths before package/path resolution. Next.js and other ESM loaders use `import(pathToFileURL(path).href)` for config and plugin loading. - -### Additional hardening layers (defense-in-depth, NOT primary isolation) - -1. **`globalThis.fetch` hardening** -- Replaced with `restrictedFetch` (loopback-only on exempt ports). Does NOT cover `http.request()`, `net.connect()`, or `dgram.createSocket()`. -2. **Node.js `--permission` flag** -- OS-level backstop for filesystem and child_process only. No network restrictions. This is a safety net, not the isolation boundary. -3. **Guest env stripping** -- `NODE_OPTIONS`, `LD_PRELOAD`, `DYLD_INSERT_LIBRARIES`, `LD_LIBRARY_PATH` stripped before spawn. -4. **Permissioned Pyodide host launches still need `--allow-worker`.** `python.rs` bootstraps through Node's internal ESM loader worker, so the host process must keep `--allow-worker` enabled even though the guest `node:worker_threads` surface is limited to a compatibility shim and does not permit real worker creation. - -## Guest `fs` and `fs/promises` Polyfill Rules - -- Guest Node `fs` and `fs/promises` polyfills share the JavaScript sync-RPC transport between `node_import_cache.rs` and `crates/sidecar/src/service.rs`. -- Node-facing `readdir` results must filter `.`/`..`. -- Async methods should dispatch under `fs.promises.*`. -- `fs.promises` methods that need real concurrency must use dedicated async bridge globals in `packages/build-tools/bridge-src/`; wrapping `fs.*Sync` inside `async` functions still serializes `Promise.all(...)` behind the first sidecar response. -- When adding WASI guest imports in `toolchain/crates/wasi-ext`, mirror the required module/object in `crates/execution/src/node_import_cache.rs`'s inline `NODE_WASM_RUNNER_SOURCE`; missing modules fail at `WebAssembly.instantiate()` before guest `main()` runs. -- Keep the embedded WASI shim in `crates/execution/src/wasm.rs` aligned with the patched wasi-libc surface used by the C command suite; overrides like `fcntl(F_SETFL)` now depend on `fd_fdstat_set_flags`, and missing imports fail at instantiation time before the guest command can do real work. -- The shared-V8 WASM runner now resolves its own module loads plus internal guest `fs.openSync` / `fs.readSync` / `fs.writeSync` / `fs.closeSync` traffic inside `crates/execution/src/wasm.rs`; if the embedded runner gains more internal file syscalls, extend that internal sync-RPC handling there instead of surfacing those requests to callers or reintroducing a host-Node runtime path. -- fd-based APIs (`open`, `read`, `write`, `close`, `fstat`) plus `createReadStream`/`createWriteStream` should ride the same bridge. -- Creation-oriented V8 `fs` helpers must preserve the guest `mode` option and resolve it against the current guest `process.umask()` before dispatching kernel-backed RPCs; dropping the `mode` field or relying on host defaults breaks Node parity for `fs.openSync`, `fs.mkdirSync`, and stream constructors that create paths. -- Guest `fs.watch` / `fs.watchFile` currently stay guest-owned polling wrappers over `fs.statSync`; keep them in `bridge-src` unless the kernel grows a real notification API. -- Runner-internal pipe/control writes must keep snapped host `node:fs` bindings because `syncBuiltinModuleExports(...)` mutates the builtin module for guests. - -## JavaScript Sync RPC - -- Timeouts and slow-reader backpressure should be enforced in `javascript.rs`, not in the generated runner. -- Track the pending request ID on the host, auto-emit `ERR_AGENTOS_NODE_SYNC_RPC_TIMEOUT` after the configured wait. -- Queue replies through a bounded async writer so slow guest reads cannot block the sidecar thread. -- Have `crates/sidecar/src/service.rs` ignore stale `sync RPC request ... is no longer pending` races after the timeout fires. -- Guest V8 timers have two host paths in `javascript.rs`: `_scheduleTimer` is an async bridge call that resolves its pending Promise later, while `kernelTimerCreate`/`kernelTimerArm`/`kernelTimerClear` are local `_loadPolyfill` dispatches that must emit `"timer"` stream events back into the V8 session so `setTimeout`/`setInterval` callbacks fire. -- In `packages/build-tools/bridge-src/`, keep Node's 1ms minimum-delay clamp on `setTimeout(0)` / `setInterval(0)` separate from `setImmediate()`. If `setImmediate()` is implemented via the timeout helper, it will accidentally inherit the clamp and drift from Node ordering/parity. -- Live guest stdin also has two delivery paths: `AGENTOS_KEEP_STDIN_OPEN` uses `"stdin"` / `"stdin_end"` stream events, while TTY-style reads use `_kernelStdinRead` and must stay forwarded to the sidecar-backed kernel fd `0` pipe so timeout and EOF remain distinguishable. -- Guest `stdin.setRawMode()` should follow the same bridge pattern as `_kernelStdinRead`: leave `_ptySetRawMode` unhandled in `LocalBridgeState`, map it to sidecar `__pty_set_raw_mode`, and have the sidecar toggle kernel PTY discipline on the guest process's fd `0` instead of keeping a local execution-only stub. -- The current V8 sync-RPC bridge effectively supports one in-flight request at a time. Do not leave long-lived network waits such as HTTP server close listeners parked on a pending sync-RPC Promise; use stream events plus short-lived follow-up RPCs so later bridge calls cannot deadlock behind the wait. - -## Runner Script Assets - -- Execution-host runner scripts materialized by `NodeImportCache` should live as checked-in assets under `crates/execution/assets/runners/` and be loaded via `include_str!`. -- The stdlib-backed V8 bridge bundle is generated from `packages/build-tools/bridge-src/` into Cargo `OUT_DIR`; `pnpm --dir packages/agentos-core build:v8-bridge` is only for manual debugging. Keep the heavier assert/util/zlib payload in `v8-bridge-zlib.js` so the main `v8-bridge.js` stays below the 500KB cap. -- Guest `os` virtualization has two env surfaces: public `process.env` is intentionally scrubbed of `AGENTOS_*`, while the real per-execution values live in the hidden runtime env (`globalThis.__agentOSProcessConfigEnv` in `javascript.rs`, mirrored from the sidecar's `prepare_guest_runtime_env(...)`). If `bridge-src` needs VM-scoped CPU/memory/home metadata, read that hidden env path or `_processConfig.env` rather than the sanitized public env, and keep it aligned with `node_import_cache.rs`. -- When `build:v8-bridge` pulls deeper undici API modules (for example `undici/lib/api/*`), keep `packages/build-tools/scripts/build-v8-bridge.mjs` aliasing any extra Node builtins they require to standalone shim files under `crates/execution/assets/undici-shims/`; those imports execute while the bundle is still bootstrapping, so they cannot depend on later `exposeCustomGlobal(...)` wiring like `_asyncHooksModule`. -- Keep `http` and `https` default agents scoped to their own module instances inside `packages/build-tools/bridge-src/`; sharing a single global default agent makes `http.request()` inherit HTTPS TLS behavior. Guest-local loopback TLS upgrades must also short-circuit inside the bridge instead of calling `net.socket_upgrade_tls`, because loopback fast-path sockets never have a kernel socket id. -- Guest HTTP client readiness in `packages/build-tools/bridge-src/` must not treat a failed kernel `net.connect()` as request-ready just because `connecting === false`; kernel-backed sockets are only ready once `_connected === true` (or they are loopback/custom preconnected sockets), otherwise denied egress can hang in `http.request()` instead of surfacing `EACCES`. -- Keep both `ServerResponse` socket-compatibility surfaces in sync inside `packages/build-tools/bridge-src/`: the main `ServerResponseBridge.socket` stub and the exported `http.ServerResponse` constructor's fake socket. If only one forwards or throws on `socket.write()`, direct `res.socket.write(...)` calls silently drop bytes on the other path. -- For guest listener-leak warnings in `packages/build-tools/bridge-src/`, route `EventEmitter` warnings through `process.emitWarning(...)` so `process.on("warning")` sees real warning objects, and lazily initialize `_maxListenersWarned` in helper paths because some inline bridge emitters (for example stream and child-process variants) do not always pass through the canonical constructor first. -- If you change generated builtin asset source in `crates/execution/src/node_import_cache.rs`, bump `NODE_IMPORT_CACHE_ASSET_VERSION` in the same file or stale materialized assets under `/tmp/agentos-node-import-cache-*` will keep serving the old code. -- The embedded WASM runner's `buildPreopens()` map must mirror `AGENTOS_GUEST_PATH_MAPPINGS`, not just `.` / `/workspace`; otherwise kernel-visible host-dir mounts like `/etc/agentos` or `/hostmnt` can succeed through `vm.readFile()` while the same path fails under `vm.exec("cat ...")`. -- Treat `crates/bridge/bridge-contract.json` as the canonical inventory for host bridge globals and calling conventions, and treat `crates/execution/assets/polyfill-registry.json` as the canonical inventory for guest `_loadPolyfill` module names. When adding or renaming a bridge global, update those files together with `crates/v8-runtime/src/session.rs`, and when exposing a new runtime-loadable builtin, update the polyfill registry together with the `_loadPolyfill` handler in `crates/execution/src/javascript.rs`. -- Guest builtin availability must stay aligned across `polyfill-registry.json`, `normalize_builtin_specifier()` in `crates/execution/src/javascript.rs`, `Module.builtinModules` plus `loadBuiltinModule()` in `packages/build-tools/bridge-src/`, and the host-node import-cache assets in `crates/execution/src/node_import_cache.rs`; if one surface still treats a denied builtin as unknown, guests will see `MODULE_NOT_FOUND` or host fallthrough instead of the intended `ERR_ACCESS_DENIED` or compatibility stub. -- The `node:vm` compatibility shim in `packages/build-tools/bridge-src/` must tag sandboxes inside `vm.createContext()` and have `vm.isContext()` check only that hidden tag; treating every object-shaped value as a context breaks libraries like jsdom that probe `isContext()` before deciding whether to re-contextify. -- `node:vm` compatibility now spans three layers: the native local bridge methods in `crates/v8-runtime/src/bridge.rs`, the stdlib-backed guest module in `packages/build-tools/bridge-src/`, and the inline shared-runtime fallback in `crates/execution/src/javascript.rs`. Keep all three aligned when changing `Script`, context isolation, or timeout semantics or sidecar builtin-conformance and execution tests will diverge. -- In `packages/build-tools/bridge-src/`, `Readable.on("data")` may auto-switch to flowing mode only from the initial `readableFlowing === null` state; if guest code already called `pause()` and set `readableFlowing === false`, preserve that explicit pause until `resume()` so packages like `tar` and `node-stream-zip` do not drain early. -- The shared-runtime `node:stream` compatibility surface for sidecar/builtin-conformance tests currently comes from the inline mini-stream module in `crates/execution/src/javascript.rs`, not the stdlib-backed `packages/build-tools/bridge-src/` path. Stream iterator/parity fixes for guest `require("stream")` need to land in that inline module and should be covered in `crates/sidecar/tests/builtin_conformance.rs`. -- The shared-runtime `node:readline` compatibility surface exercised by sidecar/builtin-conformance tests also comes from the inline module in `crates/execution/src/javascript.rs`, not only from `packages/build-tools/bridge-src/`. `question()`/async-iterator fixes need to land in that inline module and should be verified in `crates/sidecar/tests/builtin_conformance.rs`. -- Bootstrap globals injected by `packages/build-tools/scripts/build-v8-bridge.mjs` exist only to let the bundle initialize during snapshot creation. If that bootstrap layer defines `URL` or `URLSearchParams`, mark them as bootstrap stubs and have `bridge-src` ignore or replace them once the stdlib polyfills load, or the runtime can silently keep the incomplete bootstrap implementation. -- Keep `globalThis.structuredClone` guest-owned inside `packages/build-tools/bridge-src/`; falling back to the native host `structuredClone` leaks host-realm typed arrays, `Map`s, and `Date`s that fail guest `instanceof` checks even when the cloned data looks correct. -- If guest `fetch()` is powered by bundled undici, the aliased `node:stream` helpers in `crates/execution/assets/undici-shims/stream.js` must understand the bundled web-streams ponyfill too; undici's fetch path calls `finished()`, `isReadable()`, `isErrored()`, and `isDisturbed()` on `ReadableStream` response bodies, not just Node event-emitter streams. -- When testing import-cache temp-root cleanup, use a dedicated `NodeImportCache::new_in(...)` base dir so the one-time sweep stays isolated to that root. -- Active JavaScript/Python/WASM executions must hold a `NodeImportCache` cleanup guard until the child exits; otherwise dropping the engine can delete `timing-bootstrap.mjs` and related assets while the host runtime is still importing them. -- JavaScript guest validation should live in `crates/execution/tests/javascript_v8.rs`. Do not reintroduce a feature-gated host-Node guest path or a parallel host-Node compatibility suite for guest JavaScript behavior. -- Add new V8-backed JavaScript regressions to `crates/execution/tests/javascript_v8.rs` as helper functions invoked from the single top-level `javascript_v8_suite()` test, not as separate `#[test]` cases; the shared embedded runtime still trips teardown/init crashes when libtest runs those guest cases independently. -- Shared-V8 JavaScript tests should assert `uses_shared_v8_runtime()` and the absence of host guest-node launches, not `child_pid() == 0`; shared isolates still report the host runtime PID so the sidecar can manage lifecycle signals. - -## Guest Path Scrubbing - -- Guest path scrubbing in `node_import_cache.rs` should treat the real `HOST_CWD` as an implicit runtime-only mapping to the virtual guest cwd (for example `/root`) so entrypoint imports and stack traces stay usable without leaking the host path. -- Reserve `/unknown` for absolute host paths outside visible mappings or the internal cache roots. - -## CommonJS Module Isolation - -- `node_import_cache.rs` has to patch `Module._resolveFilename` and the guest-facing `Module._cache` / `require.cache` view together; wrapping only `createGuestRequire()` does not constrain local `require()` inside already-loaded `.cjs` modules. -- The V8 bridge's guest-side CommonJS helpers in `packages/build-tools/bridge-src/` must pass an explicit `"require"` mode into `_resolveModule`; omitting it falls back to import resolution and picks the wrong conditional export branch for dual packages. -- Keep `require.resolve()` parity between both CommonJS entrypoints in `packages/build-tools/bridge-src/`: `createRequire()` and the per-module `require` created in `_compile()`. If one gains `resolve.paths()` or builtin handling changes without the other, guest packages behave differently depending on how they obtained `require`. -- Eval entrypoints (`node -e` / `--eval`) must build the guest `require` from a synthetic file under the guest cwd, not from the literal `-e` token. Relative CommonJS loads in eval mode are supposed to resolve from `process.cwd()`, and using `createRequire("-e")` makes positive cases like `require('./config.json')` resolve from `"."` instead. -- Inline `node -e` / `--eval` module-mode detection in `crates/execution/src/javascript.rs` must strip comments plus string/template raw text before scanning syntax markers, and positive CommonJS signals (`module.exports`, `exports.*`, `require(...)`) should win ties over ESM markers; line-prefix heuristics misclassify bundle banners and literal text. -- For builtins that guest CommonJS should `require("node:...")`, update `createRequire()` builtin guards plus both `Module.builtinModules` and `loadBuiltinModule()` in `packages/build-tools/bridge-src/`; changing only one surface leaves `require()` behavior out of sync with `_requireFrom()` and can degrade into `ERR_ACCESS_DENIED`, `MODULE_NOT_FOUND`, or host-fallthrough mismatches. -- `crates/v8-runtime/src/execution.rs` should fall back to runtime CJS export enumeration (`Object.keys(module.exports)`) only when static extraction finds zero names or the source contains a dynamic re-export pattern static scanning cannot resolve (`__exportStar(require(...), exports)`, `Object.assign(exports, ...)`); eagerly requiring every CJS module during shim generation adds avoidable work and can trigger module side effects earlier than intended. The dynamic-re-export case is required because tsc-compiled barrels like `@sinclair/typebox/compiler` surface named exports (e.g. `TypeCompiler`) at runtime via `__exportStar`, which `extract_cjs_export_names()` cannot see. -- Inline builtin wrappers in `crates/execution/src/javascript.rs` must not call `_requireFrom()` on the same builtin subpath they implement. Subpath wrappers like `node:fs/promises` should be built from the parent builtin (`node:fs`) or a direct object, not `_requireFrom("node:fs/promises")`. -- Resolver-only coverage for `javascript.rs` should use `javascript::ModuleResolutionTestHarness` with a temp-dir fixture instead of booting a V8 isolate; mapping `/root` plus `/root/node_modules` is enough to exercise exports/imports and pnpm `.pnpm` layouts. -- `crates/execution/tests/cjs_esm_interop.rs` is the desired-behavior matrix for CJS/ESM/runtime edge cases. If an interop gap is deferred to a follow-up story, keep the strong assertion in place and mark that test `#[ignore = "US-055: ..."]` instead of weakening it to match current behavior. - -## Guest `process` Hardening - -- Guest-visible `process` hardening in `node_import_cache.rs` should harden properties on the real host `process` before swapping in the guest proxy. -- The proxy fallback must resolve via the proxy receiver (`Reflect.get(..., proxy)`) so accessors inherit the virtualized surface instead of the raw host object. -- Per-process filesystem state such as `umask` belongs in `ProcessContext` / `ProcessTable`. Kernel create/write entrypoints should read it there, and any guest Node exposure must be threaded through the JavaScript sync-RPC bridge instead of inheriting host `process` behavior. - -## Guest `child_process` Isolation - -- Strip all `AGENTOS_*` keys from the RPC `options.env` payload in `node_import_cache.rs`. -- Carry only the Node runtime bootstrap allowlist in `options.internalBootstrapEnv`. -- Re-inject that allowlisted map only when `crates/sidecar/src/service.rs` starts a nested JavaScript runtime. -- Treat string-valued `child_process` `options.shell` values as shell-enabled in both `packages/build-tools/bridge-src/` and `crates/execution/src/node_import_cache.rs`; packages like OpenCode and `cross-spawn` pass concrete shell paths such as `"/bin/sh"`, and collapsing those to `false` makes redirected commands execute as literal program names. -- Keep sync child-process stdin wired through the bridge too: `packages/build-tools/bridge-src/` `spawnSync` / `execSync` must serialize `options.input`, and the sidecar sync handlers need to write that payload to child stdin and close stdin before polling or commands like `spawnSync("/bin/cat", { input })` will diverge from host Node or hang waiting for EOF. -- Detached guest `child_process` bootstrap in `packages/build-tools/bridge-src/` must be driven by synchronous/immediate `child_process.poll` drains plus pre-`exit` completion, not a retry timer in `unref()`. Timer-based completion can race listener teardown and make long-lived detached daemons disappear when the parent exits. -- Guest `child_process.kill(signal)` in `packages/build-tools/bridge-src/` should canonicalize numeric and alias inputs through the full 1..31 POSIX table before calling the sidecar, and it should leave `child.signalCode === null` until the exit/close path runs. Node exposes the canonical signal name only after the child actually exits. -- JavaScript child-process launches in `crates/sidecar/src/execution.rs` must call `prepare_javascript_runtime_env(...)` and set `AGENTOS_SANDBOX_ROOT` just like top-level `execute()` does. If child V8 executions miss those runtime env entries, stack traces fall back to `/unknown/...`, bare-package ESM imports like `undici` stop resolving, and spawned JS CLIs silently diverge from top-level behavior. -- The V8 `node:async_hooks` shim in `packages/build-tools/bridge-src/` must preserve `AsyncLocalStorage` state across `Promise.then`, `queueMicrotask`, `process.nextTick`, timers, and `AsyncResource.runInAsyncScope`; OpenCode's Effect instance context depends on that propagation during streamed tool execution. -- In `crates/execution/src/node_import_cache.rs`, WASM child-process stdio can target delegate-managed guest fds rather than real host OS fds. Keep synthetic-pipe routing aligned with `delegateManagedFdWrite`/`delegateManagedFdClose`, retain those delegate fds for the child lifetime, and only release the final close after child exit; writing streamed stdout/stderr with raw host `writeSync(fd, ...)` breaks redirected shell output. -- In that same WASM host-process bridge, `child_process.poll` returning `ECHILD` after an `exit` event's trailing-drain pass is terminal, not a new fault. The sidecar can remove the child as soon as it reports exit, so post-exit drain loops must stop on `ECHILD` instead of converting a successful pipeline into `WASI_ERRNO_FAULT`. -- For sidecar-managed WASM guests, `fd_write` on fd 1 / fd 2 must go through the kernel stdio bridge (`__kernel_stdio_write`) rather than guest `process.stdout` / `process.stderr`. Falling back to the host stream inside the shared sidecar process breaks VM output isolation, bypasses PTYs and `/dev/stdout` redirection, and can make tests pass by snooping host stdout instead of the kernel-routed output path; keep any execution-only fallback scoped to non-sidecar harnesses that are not running inside a VM. -- In the standalone WASI runner path, only opt into `__kernel_stdio_write` / `__kernel_stdin_read` when the process is sidecar-managed or `AGENTOS_WASI_STDIO_SYNC_RPC=1` is set. Helper-style Rust tests still expect bootstrap stdout/stderr to surface as queued `WasmExecutionEvent::{Stdout,Stderr}` events, so internal `fs.writeSync(1|2, ...)` sync RPCs must be translated inside `crates/execution/src/wasm.rs` instead of leaking out as raw sync-RPC traffic. -- Mirror guest-stdin fixes across both WASI host shims: `crates/execution/src/wasm.rs` and `crates/execution/src/node_import_cache.rs` must special-case guest fd `0` before passthrough-handle delegation, or sidecar-managed stdin silently falls back to host `fs.readSync(...)` and pipe-heavy shell commands hang behind the wrong read path. -- Sidecar-managed WASI fd `0` must honor `FDFLAGS_NONBLOCK`: use a zero-timeout kernel stdin probe and return `EAGAIN` when no bytes are ready. Blocking mode must keep using a parked kernel read instead; otherwise a polling guest service can monopolize the WASM thread and starve its child process output. -- When the standalone WASI runner still uses in-band `__AGENTOS_WASM_SIGNAL_STATE__:` lines, parse stdout/stderr as line-oriented byte streams inside `crates/execution/src/wasm.rs` and treat the marker only when it occupies its own newline-terminated line; preserve every other byte verbatim and reassemble markers that arrive split across chunks. -- In the same WASM host-process path, synthetic pipes must initialize both `producers` and `consumers`, and consumer registration must flush any chunks buffered before the child attached. Shell builtins can write into a pipe before a spawned child like `wc` registers its stdin consumer, so registration also needs to close child stdin immediately when no writers or producers remain. -- In that synthetic-pipe path, keep pipe FD mappings alive while a registered producer or consumer is still attached, even if the guest shell closes its local duplicate of the pipe endpoint. Pipeline writers/readers outlive the shell's bookkeeping FDs, and queued bytes should treat registered consumers as active readers even after `readHandleCount` drops to zero. -- The WASM runner's read-only `path_open` guard in `crates/execution/src/node_import_cache.rs` must allow non-mutating open flags such as `O_DIRECTORY`; only create/truncate/exclusive flags and write rights should return `EACCES`, or read-only traversal commands like `find`, `fd`, and `ls ` will fail to enumerate directories. -- Keep the WASM preopen rights metadata aligned between `buildPreopens()` in `crates/execution/src/node_import_cache.rs` and the inline WASI shim in `crates/execution/src/wasm.rs`: `fd_fdstat_get` and `path_open` must read the same per-preopen `rightsBase` / `rightsInheriting` values, or read-only tiers silently regain write access through the default "all rights" fallback. -- WASM execution tests that poll `WasmExecution::poll_event_blocking()` need to handle `WasmExecutionEvent::SyncRpcRequest(_)` explicitly unless the test is asserting that control-plane behavior; the runtime includes sync RPC traffic in the same event stream as stdout/stderr/signal/exit events. `WasmExecution::wait()` only auto-services kernel stdio writes (`__kernel_stdio_write`) so simple callers still collect stdout/stderr, and it should fail fast on any other unexpected pending sync RPC instead of silently hanging. -- The host WASI runner's full-permission preopens must include both `'.'` and `'/workspace'` mapped to `process.cwd()`. Child commands that receive `cwd: "/workspace"` from the sidecar still resolve relative paths through the WASI `.` preopen, so omitting it makes `cat note.txt`/redirects fail even when the guest cwd is otherwise correct. -- In the inline WASI shim in `crates/execution/src/wasm.rs`, `path_open` must resolve the target beneath the specific descriptor's `hostPath`, not by bouncing through the global guest-path mapping table; otherwise `../` segments can escape one preopen and land in sibling mounts or host paths like `/etc/passwd`. -- WASM child-process launches should keep the guest command name in `ResolvedChildProcessExecution.process_args[0]` / WASI `argv[0]`; `execution_args` is the suffix after that command name. PATH-resolution tests for mounted commands should assert the full argv vector, not just the trailing args. -- Projected native binaries that hit the WASM path must fail with the explicit sidecar-facing code `ERR_NATIVE_BINARY_NOT_SUPPORTED` based on their magic bytes (`ELF`, `Mach-O`, `PE/COFF`) before any `WebAssembly.compile()` attempt; do not broaden regressions to accept fallback `CompileError: WebAssembly.Module()` output. - -## Guest Networking Rules - -- Guest Node `net` Unix-socket support follows the same split as TCP: resolve guest socket paths against `host_dir` mounts when possible, otherwise map them under the VM sandbox root on the host, keep active Unix listeners/sockets in `crates/sidecar/src/service.rs`, and mirror non-mounted listener paths into the kernel VFS so guest `fs` APIs can see the socket file. -- When proving guest `http.request()` uses the kernel socket path instead of the legacy loopback shortcut, point it at a guest `net.createServer()` that speaks raw HTTP. `http.createServer()` can still succeed through the deprecated `net.http_request` loopback dispatch, so a plain TCP listener is the reliable regression target. -- Guest `http.request()` / `http.get()` calls targeting a guest loopback `http.createServer()` must stay on the bridge's raw-socket HTTP path. Do not send `socket._loopbackServer` sockets through the undici dispatcher; the sidecar-managed loopback transport already speaks raw HTTP bytes and the undici path can hang waiting on semantics that never arrive. -- When a guest Node networking port stops using real host listeners, mirror that state in `crates/sidecar/src/service.rs` `ActiveProcess` tracking and consult it from `find_listener`/socket snapshot queries before falling back to `/proc/[pid]/net/*`; procfs only sees host-owned sockets, not sidecar-managed polyfill listeners. -- Sidecar-managed loopback `net.listen` / `dgram.bind` listeners now use guest-port to host-port translation in `crates/sidecar/src/service.rs`: preserve guest-visible loopback addresses/ports in RPC responses and socket snapshots, but use the hidden host-bound port for external host-side probes and test clients. -- V8 `node:dgram` support in `packages/build-tools/bridge-src/` depends on both `loadBuiltinModule("dgram")` and `"dgram"` appearing in `Module.builtinModules`; keep those lists aligned, and keep the generated bridge payloads aligned with the current sidecar RPC contract (`createSocket` object payload, `send` bytes plus `{ address, port }`, `poll` object-or-null responses). -- Sidecar JavaScript networking policy should read internal bootstrap env like `AGENTOS_LOOPBACK_EXEMPT_PORTS` from `VmState.metadata` / `env.*`, not `vm.guest_env`; `guest_env` is permission-filtered and may be empty even when sidecar-only policy still needs the value. -- When adding a new raw V8 bridge method used by WASM host shims, keep `crates/execution/src/wasm.rs`, `crates/execution/src/v8_runtime.rs`, `crates/v8-runtime/src/session.rs`, `crates/bridge/bridge-contract.json`, and `packages/build-tools/bridge-src/` aligned, then rebuild `cargo build -p agentos-v8-runtime`; otherwise the method can compile cleanly while still being unavailable at runtime. -- When the embedded V8 runtime is shared across the whole process, V8 session ids must stay globally unique and `JavascriptExecution` teardown must terminate then destroy the session; reusing ids or abruptly dropping a live session can leak state into later tests even when isolated cases pass. -- The direct embedded-runtime path should stay at the `shared_embedded_runtime()` / `EmbeddedV8SessionHandle` boundary in `crates/execution/src/v8_host.rs`; keep `crates/execution`'s local `v8_ipc::BinaryFrame` conversions at that boundary and do not reintroduce a local `UnixStream`/reader-thread transport inside the process. - -## Guest `tls` - -- Guest Node `tls` should stay layered on the guest `net` polyfill rather than importing host `node:tls` directly. -- Client connections must pass a preconnected guest socket into `tls.connect({ socket })`. -- Server handshakes should wrap accepted guest sockets with `new TLSSocket(..., { isServer: true })` and emit `secureConnection` from the wrapped socket's `secure` event. - -## Guest `dns` - -- When a newly allowed Node builtin still has bypass-capable host-owned helpers or constructors (for example `dns.Resolver` / `dns.promises.Resolver`), replace those entrypoints with guest-owned shims or explicit unsupported stubs before adding the builtin to `DEFAULT_ALLOWED_NODE_BUILTINS`; inheriting the host module is only safe for exports that cannot escape the kernel-backed port. -- When adding a Node builtin subpath such as `node:dns/promises`, keep every guest-module surface in sync: `normalize_builtin_specifier()` and `builtin_named_exports()` in `javascript.rs`, `Module.builtinModules` plus `loadBuiltinModule()` in `bridge-src`, the import-cache builtin assets and rewrite table in `node_import_cache.rs`, and the esbuild alias shims under `crates/execution/assets/undici-shims/`. -- Socket-like compatibility shims in `bridge-src` need both `_readableState.endEmitted` and `_readableState.ended`, and they must flip those fields together on EOF and destroy paths; packages like `ssh2`, `ssh2-sftp-client`, and `ws` inspect those internals directly instead of waiting for public stream events. -- `fs.mkdtempSync()` in `bridge-src` should keep Node's six-character alphanumeric suffix shape while sourcing entropy from six random bytes, and it must create the directory without `recursive: true` so existing-path collisions surface as `EEXIST` instead of silently reusing a directory. - -## Python Execution - -- Python execution in `python.rs` should keep `poll_event()` blocked until a real guest-visible event arrives or the caller timeout expires; filtered stderr/control messages are internal noise. -- `wait(None)` should still enforce the per-run `AGENTOS_PYTHON_EXECUTION_TIMEOUT_MS` cap. -- `wait()` should bound accumulated stdout/stderr via the hidden `AGENTOS_PYTHON_OUTPUT_BUFFER_MAX_BYTES` env knob rather than growing buffers without limit. -- Node heap caps from `AGENTOS_PYTHON_MAX_OLD_SPACE_MB` need to apply to both prewarm and execution launches without leaking those control vars into guest `process.env`. -- Warmup marker fingerprints for guest assets must include mutation data (`size` plus `mtime`/`mtime_nsec`), not just inode identity; in-place rewrites of Pyodide or WASM assets can preserve the inode and still need to invalidate prewarm stamps. -- Pyodide bootstrap hardening in `node_import_cache.rs` must stay staged: `globalThis` guards can go in before `loadPyodide()`, but mutating `process` before `loadPyodide()` breaks the bundled Pyodide runtime under Node `--permission`. -- Python RPC shims in `crates/execution/assets/runners/python-runner.mjs` should translate JS bridge failures into Python-native exceptions (`PermissionError`, `FileNotFoundError`, `OSError`) instead of leaking `JsException`, and Python `subprocess.run()` should inherit the VM cwd from sidecar process state rather than Pyodide's internal `/home/pyodide` working directory. -- Pyodide reads `packageBaseUrl` only in `loadPyodide()`, and it checks its package cache before it downloads. Keep bundled wheels seeded in the package cache, and keep the sidecar's sha256 check on every write into the cache. When guest Python needs HTTP wheels, patch `pyodide.http.pyfetch` through the Python `httpRequestSync` bridge so `micropip` obeys sidecar network policy and loopback exemptions instead of bypassing them. -- Guest runtime identity defaults must stay aligned across JS, WASM, and Python: keep `HOME` bound to the kernel user's homedir, keep `PWD` bound to the execution cwd, feed those values into the Pyodide bootstrap env, and make sure Python `execute()` requests still pass through `prepare_guest_runtime_env(...)` instead of bypassing the shared runtime-env assembly. -- The shared runtime env contract also includes a stable guest `PATH` plus internal-env filtering: `prepare_guest_runtime_env(...)` should supply the canonical guest search path, `python-runner.mjs` should expose that `PATH` inside `os.environ`, and the WASM `AGENTOS_GUEST_ENV` payload must strip internal control vars like `AGENTOS_*` / `NODE_SYNC_RPC_*` before they reach guest-visible WASI env. -- Pyodide `micropip` support must keep guest `js` / `pyodide_js` imports blocked for user Python code while exposing only a narrow internal compat surface to `micropip` and `pyodide.http`; widening that exception re-opens host escape hatches. -- `python-runner.mjs` must suppress `loadPyodide()`/micropip progress banners such as `Loading ...` and `Loaded ...` from guest stdout; sidecar callers and tests often parse stdout as program output or JSON, so those bootstrap logs have to stay internal. -- When `python-runner.mjs` or other bundled execution assets change, bump `NODE_IMPORT_CACHE_ASSET_VERSION` in `node_import_cache.rs` if the temp materialization needs to refresh immediately; otherwise stale `/tmp/agentos-node-import-cache-*` contents can mask the update during local test runs. diff --git a/crates/execution/Cargo.toml b/crates/execution/Cargo.toml deleted file mode 100644 index bff59311b7..0000000000 --- a/crates/execution/Cargo.toml +++ /dev/null @@ -1,44 +0,0 @@ -[package] -name = "agentos-execution" -version.workspace = true -edition.workspace = true -license.workspace = true -repository.workspace = true -description = "Native execution plane scaffold for agentos" -build = "build.rs" -# Large Pyodide runtime assets are staged at build time (copied from the -# in-tree assets directory during workspace builds, or downloaded from the -# release CDN when building the published crate) so the packaged crate stays -# under the registry size limit.

Do not add agentos sidecar, bridge, S3, SQLite, host-disk, or registry coupling here. - The crate intentionally contains separate filesystem type universes under explicit modules while the consolidation is in progress. Do not glob-merge names that would confuse those boundaries. -- Concrete environment-bound backends belong in `agentos-vfs`. +- Concrete environment-bound backends belong in `agentos-vfs-storage`. - The `chunked` engine deliberately decouples the `MetadataStore` from the `BlockStore`: blocks are content-addressed, opaque, and self-describing only as a set, while the directory tree, inode table, chunk map, and refcounts live entirely in the metadata store. The engine makes **no self-containment promise** about either half. Pairing a block store with a metadata store, and ensuring the metadata store is durable and co-located with whatever lifecycle the blocks need, is the **caller's responsibility** (the sidecar plugin / client config that wires the backends), not the engine's. So e.g. an `S3BlockStore` backed by a local `SqliteMetadataStore` is a valid, intended configuration; the engine does not assume blocks carry enough information to reconstruct the tree, and "the metadata lives elsewhere than the blocks" is by design, not a defect. If a deployment needs the tree to survive loss of the local metadata, it must choose a durable metadata store (e.g. the callback backend) — that is a wiring decision, not an engine concern. - The engine data plane (`chunked`/`object` engines, `MetadataStore`/`BlockStore`/`ObjectBackend` impls, `CachedMetadataStore`, and the `MountedEngineFileSystem` adapter) assumes **single-writer semantics**: one writer owns a given filesystem/mount at a time. Block refcounting, cache invalidation, and read-modify-write chunk edits are correct only under that assumption. There is no cross-process coordination, locking, or conflict resolution; concurrent writers against the same metadata/block backing store (e.g. two sidecars sharing one S3 prefix + SQLite file, or a shared callback store) can corrupt refcounts and orphan or double-free blocks. Do not rely on these engines for multi-writer/shared-storage scenarios without adding an external coordination layer. - `MetadataStore::snapshot`/`fork` are intentionally not production-GC-ready yet. There is no snapshot deletion API, so snapshot-pinned block refs are permanent for now. Do not wire snapshot/fork into plugins that need block reclamation until snapshot lifecycle and persistent snapshot rows are implemented. diff --git a/crates/vfs/Cargo.toml b/crates/vfs-core/Cargo.toml similarity index 58% rename from crates/vfs/Cargo.toml rename to crates/vfs-core/Cargo.toml index 21a1f8721d..5dfcef90e0 100644 --- a/crates/vfs/Cargo.toml +++ b/crates/vfs-core/Cargo.toml @@ -6,11 +6,17 @@ license.workspace = true repository.workspace = true description = "Generic async virtual filesystem primitives" -# Published as `agentos-vfs-core`, but the lib is named `vfs` so the -# workspace-wide `vfs = { package = "agentos-vfs-core" }` alias and this -# crate's own `tests/*.rs` (`use vfs::...`) resolve it by that name. +[features] +default = ["package-filesystem"] +package-filesystem = [ + "dep:memmap2", + "dep:tar", + "dep:vbare", + "dep:vbare-compiler", +] + [lib] -name = "vfs" +name = "agentos_vfs_core" [dependencies] anyhow = "1" @@ -20,20 +26,26 @@ blake3 = "1" serde = { version = "1.0", features = ["derive"] } serde_bare = "0.5" serde_json = "1.0" -vbare = { workspace = true } +vbare = { workspace = true, optional = true } # Drop-in std::time replacement: re-exports std on native, uses js_sys::Date / # performance.now() on wasm32 (where std SystemTime/Instant abort). web-time = "1.1" [build-dependencies] -vbare-compiler = { workspace = true } +vbare-compiler = { workspace = true, optional = true } [target.'cfg(not(target_arch = "wasm32"))'.dependencies] -agentos-runtime = { workspace = true } -memmap2 = "0.9" -tar = "0.4" -tokio = { version = "1", features = ["rt", "rt-multi-thread"] } +memmap2 = { version = "0.9", optional = true } +tar = { version = "0.4", optional = true } tracing = "0.1" [dev-dependencies] tokio = { version = "1", features = ["macros", "rt", "rt-multi-thread"] } + +[[test]] +name = "package_format" +required-features = ["package-filesystem"] + +[[test]] +name = "posix_tar_fs" +required-features = ["package-filesystem"] diff --git a/crates/vfs/assets/base-filesystem.json b/crates/vfs-core/assets/base-filesystem.json similarity index 99% rename from crates/vfs/assets/base-filesystem.json rename to crates/vfs-core/assets/base-filesystem.json index bdb7b06ec7..2365bebdaf 100644 --- a/crates/vfs/assets/base-filesystem.json +++ b/crates/vfs-core/assets/base-filesystem.json @@ -6,6 +6,7 @@ "builtAt": "2026-06-23T03:47:12.644Z", "transforms": [ "Normalize HOSTNAME to agentos", + "Allow traversal into the agentOS /root/node_modules compatibility projection", "Preserve the captured user-level environment and filesystem layout as the agentos base layer", "Add the non-Alpine /workspace directory (default agent working directory) owned by the base user", "Restore Alpine 3.22's /etc/services database and add the VM's Docker-style /etc/hosts entries for libc lookup parity" @@ -336,7 +337,7 @@ { "path": "/root", "type": "directory", - "mode": "700", + "mode": "711", "uid": 0, "gid": 0 }, diff --git a/crates/vfs/build.rs b/crates/vfs-core/build.rs similarity index 97% rename from crates/vfs/build.rs rename to crates/vfs-core/build.rs index 6f75aa4ca7..c0a3162f27 100644 --- a/crates/vfs/build.rs +++ b/crates/vfs-core/build.rs @@ -11,6 +11,7 @@ fn main() { PathBuf::from(env::var("CARGO_MANIFEST_DIR").expect("CARGO_MANIFEST_DIR must be set")); let out_dir = PathBuf::from(env::var("OUT_DIR").expect("OUT_DIR must be set")); + #[cfg(feature = "package-filesystem")] stage_package_format_schema(&manifest_dir, &out_dir); let workspace_fixtures = [ @@ -36,6 +37,7 @@ fn main() { ); } +#[cfg(feature = "package-filesystem")] fn stage_package_format_schema(manifest_dir: &Path, out_dir: &Path) { let source_schema = manifest_dir.join("package-format").join("v2.bare"); let schema_dir = out_dir.join("package-format-schema"); diff --git a/crates/vfs/package-format/v2.bare b/crates/vfs-core/package-format/v2.bare similarity index 95% rename from crates/vfs/package-format/v2.bare rename to crates/vfs-core/package-format/v2.bare index 372b4534c4..190bc62108 100644 --- a/crates/vfs/package-format/v2.bare +++ b/crates/vfs-core/package-format/v2.bare @@ -11,13 +11,13 @@ # Enum members are append-only because their order is the on-wire ordinal. # # Tooling: two packers encode this schema and must stay behaviorally identical — -# Rust `crates/vfs/src/package_format/pack.rs` (bench/test fixtures, canonical) +# Rust `crates/vfs-core/src/package_format/pack.rs` (bench/test fixtures, canonical) # and TS `packages/agentos-toolchain/src/aospkg.ts` (what `agentos-toolchain # build`/`pack` emit as `dist/package.aospkg`).

When changing guest self-signal behavior (`process.kill`, `process.abort()`, signal-shape exit reporting), mirror the top-level bookkeeping there too or spawned Node children will regress to `unsupported JavaScript sync RPC method process.kill` and report plain exit codes. - Nested JavaScript child signal registration currently arrives through the sync-RPC method `process.signal_state` in `src/execution/child_process.rs`, not just `ActiveExecutionEvent::SignalState`. When fixing descendant `SIGCHLD` or job-control behavior, keep the nested bookkeeping aligned with the top-level `src/service.rs` handler or grandchildren will silently lose their registered signal handlers. -- The sidecar protocol `Authenticate` handshake must carry `agentos_bridge::bridge_contract().version`; `src/service.rs` should reject mismatches with `bridge_version_mismatch` before opening a connection so bridge-contract drift fails fast instead of crashing later on the first divergent RPC. +- The sidecar protocol `Authenticate` handshake must carry `agentos_vm_host_interface::bridge_contract().version`; `src/service.rs` should reject mismatches with `bridge_version_mismatch` before opening a connection so bridge-contract drift fails fast instead of crashing later on the first divergent RPC. - `plugins/host_dir.rs` metadata writes must keep the old symlink-leaf safety contract for plain ops (`chmod`/`chown`/`utimes` still reject symlink leaves), while the richer timestamp path should only mutate symlink metadata when the caller explicitly requests nofollow semantics (`lutimes` / `utimes_spec(..., false)`). - Mounted filesystem shutdown now happens explicitly during `src/vm.rs` disposal/reconfigure, not just in `MountTable::drop`. Bridge-backed mounts can therefore emit `SidecarRequestPayload::JsBridgeCall` during teardown, and host-visible flush failures should surface as the structured event `filesystem.mount.shutdown_failed` with the mount metadata plus the original error code/message. - Guest runtime env setup in `src/execution/launch.rs` must add writable `host_dir` / `module_access` mount roots to `AGENTOS_EXTRA_FS_WRITE_PATHS`, not just the VM shadow cwd. Without those extra write roots, guest `fs.*` bridge calls misclassify writable mounts as read-only (`EROFS`) and cross-mount rename tests never reach the intended `EXDEV` path. -- The native sidecar must run UNPRIVILEGED (non-root uid) AND under gVisor/runsc (Rivet Compute), so host-mount confinement cannot assume either root DAC bypass or Linux-only syscalls. Two consequences bind the `confine` boundary: (1) `openat2(RESOLVE_BENEATH)` is unsupported under gVisor, so the resolve-beneath walk must use plain `openat(2)` (see the `confine` module); (2) because the sidecar uid is not root, DAC permission checks are real and are NOT masked away — so confinement must not require MORE access than POSIX does.

Rules: - `stat`/`exists` use `confine::resolve_parent_beneath` + `fstatat`/`fstat` against `(parent_fd, leaf_name)` — never `open_beneath(O_RDONLY)` on the leaf, which would falsely report a statable-but-unreadable file (mode `0600` owned by another uid, or `0000`) as missing/`EACCES` under a non-root sidecar. - `chown`/`utimes` use `split_parent` + `fchownat`/`utimensat(.., AT_SYMLINK_NOFOLLOW/NoFollowSymlink)` after `reject_symlink_leaf`. `AT_SYMLINK_NOFOLLOW` on the mutation both keeps the leaf read-free AND closes the check→mutate symlink-swap TOCTOU (a leaf swapped to a symlink after the reject-check is operated on in place, staying confined, never followed to an escaped host path). - `chmod` is the ONE deliberate exception: `fchmodat` has no `AT_SYMLINK_NOFOLLOW`, so a leaf-free `chmod` cannot close that swap race. `chmod` therefore keeps the `open_metadata_beneath` leaf open (`O_RDONLY | O_NOFOLLOW`) + `fchmod`, accepting the non-root READ requirement in exchange for TOCTOU safety.

Sanctioned only in the +//! kernel DNS/socket plane, the sidecar host-net chokepoint +//! (`sidecar::execution`), the embedded V8 runtime IPC pair, and +//! host-backed storage plugins. +//! * process -- `std::process::Command` / `tokio::process` / OS `fork`. +//! Sanctioned only where agentos spawns its own helper process (the +//! client transport that launches the sidecar).

Consumers cannot provide actor + source, callbacks, lifecycle hooks, a custom VFS object, or arbitrary actor + options. +- The hosted actor exposes only sandbox functionality.

A replacement normalizes the entire input; + omitted properties reset to Core-owned defaults. +- Graceful runtime shutdown and process draining are deferred follow-up work. + This refactor promises only the existing bounded Core replacement behavior. +- Configuration actions use dotted RivetKit action names. The generated + TypeScript client presents those actions as nested objects. +- The TypeScript hosted actor is deleted before the Rust replacement is built. + It is not incrementally ported. +- Actor Runtime Socket support is removed before the Rust actor is introduced. +- During the proof of concept, actor and Core persistence use small local SQLite + adapters. The adapters preserve the eventual Rivet SQLite boundary and are not + allowed to leak local-database details into Core APIs. +- The executable may expose two entry points: the normal Rivet actor process and + an internal native sidecar process. Neither entry point carries ACP. +- Registry software is not published to or resolved from npm. `.aospkg` + artifacts are published at stable HTTPS URLs backed initially by + S3-compatible object storage. The hosted actor installs URL sources only; + trusted embedded Core callers may also install from local paths. +- The package cache has a process-local content-addressed layer. A separate + central actor stores an approximate, low-frequency hot-package set for startup + preloading.

Static Rust actor + +The actor owns only responsibilities that require Rivet actor context: + +- Rivet actor startup, shutdown, actions, events, and keep-awake integration. +- Loading creation input and durable desired configuration. +- Persisting configuration revisions and coordinating runtime reconciliation. +- Translating serializable action DTOs to one-for-one Core client calls. +- Mapping Core errors into stable typed actor errors without hiding their cause. +- Connecting preview-token request paths to the VM networking API. +- Routing URL-based package installation and consulting process-local package + services. +- Emitting bounded process, terminal, runtime, and schedule events. + +It must not implement filesystem semantics, process policy, language execution, +networking policy, permission decisions, guest defaults, or package projection. +Those remain in Core, the sidecar, the kernel, and the VFS. + +### 2. Rust Core client + +The Rust client is the actor's direct API. It supplies typed requests and +responses for VM lifecycle, files, processes, terminals, language execution, +networking, packages, and scheduling. Actor actions should normally contain +validation of the wire DTO, one Core call, and transport-safe encoding of the +result. + +If actor implementation requires behavior missing from the Rust client, add it +to the shared Core/sidecar contract first. Do not implement the behavior only in +the actor. + +### 3. TypeScript Core + +`@rivet-dev/agentos` remains the embedded TypeScript API. It keeps host +bindings because an embedding application can provide in-process callbacks. +It loses all agent, session, ACP, Actor Runtime Socket, and actor-specific code. +Its sandbox behavior must remain in lockstep with the Rust client and sidecar. + +### 4. Native sidecar, runtime, kernel, and VFS + +These components remain the trusted enforcement point. They own VM defaults, +permissions, resource limits, the process and socket tables, filesystem +semantics, language runtimes, package projection, and the `/opt/agentos` view. +Removing ACP must leave a generic sidecar that is usable by both the embedded +TypeScript Core and the static Rust actor. + +### 5. SQLite adapters + +The proof of concept uses local SQLite behind explicit adapter interfaces. The +physical database may be shared, but schema ownership is independent: + +- Filesystem storage owns `agentos_fs_*` and `agentos_fs_schema_version`. +- Core durable state owns `agentos_core_*` and + `agentos_core_schema_version`. +- The Rust actor owns `agentos_actor_*` and + `agentos_actor_schema_version`. + +Every table is `STRICT`. Each owner migrates only its own namespace and advances +its own version in the same transaction. There is no adoption or compatibility +path for legacy `agentos_vfs_*`, `agentos_session*`, or `agent_os_*` tables. + +### 6. Package source and package cache + +Core resolves a closed package source enum: remote URL or trusted embedded local +path. Both paths produce verified immutable `.aospkg` content in the process +cache, which is memory-mapped and projected by VFS under `/opt/agentos`. The +hosted actor exposes only the URL variant and can never construct a local-path +source. Cache identity is the content digest, not the URL. + +### 7. Preload coordinator actor + +The coordinator stores an approximate bounded hot set of exact URL, digest, and +size identities. +Each agentOS process reads it once during startup and warms the process-local +cache before becoming ready, subject to a strict timeout. Usage messages are +coalesced in each process and flushed infrequently. Missed, duplicated, stale, or +reordered messages affect only cold-start performance. + +### 8. Generated TypeScript contract + +The Rust action and event contract is the source of truth. An agentOS-specific +prototype in `packages/agentos-bindgen` exports schema and generates TypeScript +without modifying RivetKit. Possible later generalization is not part of this +refactor. The generated client adds ergonomic binary conversions and event +subscriptions but no policy, defaults, persistence, or state machine. + +## Internal component API surfaces + +These are implementation boundaries, not public actor actions. Names are +illustrative Rust traits or internal actor actions; the important constraint is +that dependencies point inward toward Core and outward toward infrastructure +through narrow adapters. + +### Core runtime adapter + +```text +start(config, event_sink) -> RuntimeHandle +status(handle) -> CoreRuntimeStatus +classify_config_change(current, candidate) -> ReconcilePlan +apply_live(handle, plan) -> AppliedChange +stop(handle, deadline) -> ShutdownResult +``` + +All filesystem, process, terminal, context, language, network, software, and cron +methods are supplied by the shared Rust Core client using the public operation +names. The actor adapter adds no parallel versions of them. + +### Actor state store + +```text +initialize(create_input) -> ConfigSnapshot +get_config() -> ConfigSnapshot +prepare_replacement(expected_revision, input) -> NormalizedCandidateConfig +commit_desired(candidate) -> ConfigSnapshot +mark_applied(revision, runtime_generation) -> ConfigSnapshot +mark_failed(revision, typed_issue) -> ConfigSnapshot +``` + +This interface is backed temporarily by local SQLite and later by Rivet SQLite. +It owns `agentos_actor_*` only. + +### Core and filesystem database adapters + +```text +transaction(callback) -> result +execute(statement, parameters) -> ExecuteResult +query(statement, parameters) -> bounded rows +close() -> result +``` + +The actual trait should prevent raw cross-namespace migration access where +practical. It must not expose a local file path as part of the durable API. + +### Hosted filesystem registry + +```text +register(id, config_schema, capabilities, factory) +validate(descriptor) -> ValidatedFilesystemDescriptor +open(validated_descriptor, actor_storage) -> CoreFilesystem +``` + +The static binary constructs this registry from a fixed whitelist. Actor input +can select and configure a registered filesystem but cannot add a factory or +identify a host path. + +### Package source adapter + +```text +resolve(Url { url, expected_digest? }, limits) -> VerifiedPackage +resolve(Path { path, expected_digest? }, limits) -> VerifiedPackage +project(packages, runtime_generation) -> InstalledPackageSet +``` + +Only embedded trusted Core callers can create `Path`. The actor contract +contains only `Url`. Both variants publish verified content into the same +digest-keyed cache and projection path. + +### Process-local package cache + +```text +get(digest) -> CacheHit | CacheMiss +get_or_fetch(remote_source, fetcher) -> CachedArtifact +pin(digest, runtime_generation) -> Pin +release(pin) -> void +warm(resolved_remote_sources, deadline) -> WarmReport +record_access(digest) -> void +stats() -> CacheStats +``` + +The cache is immutable by digest, byte-bounded, LRU-evicted, and single-flight +per digest. + +### Preload coordinator actor + +| Internal action | Purpose | +| --- | --- | +| `preload.getPlan` | Read one bounded exact-artifact hot set at process startup | +| `preload.recordUsage` | Submit one coalesced process observation window | +| `preload.replaceBaseline` | Replace the operator-managed seed set, if action-managed | +| `preload.status` | Inspect bounded coordinator health and plan metadata | + +No public agentOS action forwards these calls. + +### Preview token store + +```text +create(port, expires_at) -> PreviewToken +resolve(token, now) -> port | expired +expire(token) -> void +``` + +Tokens are actor SQLite rows used by the actor's ordinary `on_fetch` route. They +survive sleep until their TTL and never expose arbitrary host routing. + +### RivetKit scheduling adapter + +```text +cron_set(name, expression, "process.exec", args) -> void +cron_list() -> bounded jobs +cron_delete(name) -> bool +``` + +The actor uses RivetKit's existing durable cron storage and wakeup machinery. A +scheduled private action invokes the same Core process execution path as a direct +`process.exec` action. + +### Contract generator + +```text +export_schema(rust_actions, rust_events, rust_errors) -> ContractSchema +generate_typescript(contract_schema) -> package sources +verify_contract(contract_schema, registered_handlers) -> result +``` + +This contract generator lives in the agentOS workspace package. The generated +client uses the vanilla RivetKit actor proxy and recreates nested objects from +dotted names. + +## Actor lifecycle + +1. Rivet creates or wakes the `agentOS` actor with optional `config` creation + input. +2. The actor opens its SQLite adapter and migrates only `agentos_actor_*`. +3. On first creation, RivetKit passes creation input to `create_state`; validation + failure aborts creation. Once state exists, later `getOrCreate` input is not an + update and `config.set` is the only mutation path. +4. The process reads the preload coordinator once and begins bounded package + warming. Readiness waits for warming only until the configured startup + deadline. A timeout is reported but does not corrupt desired state. +5. Core resolves desired package URLs, verifies and caches immutable content, + constructs the VM, and projects `/opt/agentos` from memory-mapped bytes. +6. Health becomes ready only after the desired configuration has been applied + and required startup packages are available. It reports degraded or failed + state with typed causes rather than returning a false success. +7. Actions call Core. Live events are forwarded through bounded actor event + paths, while replayable process and terminal output comes from bounded Core + buffers. +8. A complete normalized config replacement is durably committed with a + monotonic revision. The actor applies it live when Core supports that change; + otherwise it records that runtime replacement is required. + +## Durable configuration contract + +The public shape below is conceptual. Exact field types should reuse generated +Core protocol DTOs rather than copy handwritten actor types. + +```ts +interface AgentOsActorCreateInput { + config?: AgentOsActorConfigInput; +} + +interface AgentOsActorConfigInput { + user?: VmUserConfig; + environment?: Record; + software?: RemotePackageSource[]; + allowedNodeBuiltins?: string[]; + highResolutionTime?: boolean; + filesystem?: { + root?: HostedRootFilesystemDescriptor; + mounts?: HostedMountDescriptor[]; + }; + permissions?: PermissionConfig; + limits?: AgentOsLimits; + preview?: PreviewPolicy; +} + +interface AgentOsConfigSnapshot { + revision: number; + desired: CompleteAgentOsActorConfig; + appliedRevision: number | null; + state: "applying" | "ready" | "restart_required" | "failed"; + issues: ConfigIssue[]; +} +``` + +Every property has a Core-owned default. Creation and `config.set` pass the input +through the same Core normalizer, and the actor persists the resulting complete +document. The actor does not maintain copied default constants. + +Mutation is full replacement: + +```ts +interface SetConfigInput { + expectedRevision?: number; + config: AgentOsActorConfigInput; +} +``` + +Omission means reset to the default, including for arrays and maps. A caller that +wants to preserve existing values reads the complete config with `config.get`, +modifies it, and writes it back with `expectedRevision`. Explicit empty lists, +empty maps, `false`, and valid zero values remain distinct from omission. There +is no merge patch, operation list, or array-specific behavior. + +`expectedRevision` provides optional optimistic concurrency. Validation and +resource preparation happen before commit where possible. If reconciliation +fails after a commit, the desired revision stays durable and the snapshot exposes +the failure; the actor must not claim that the previous revision is current. + +Operator-only settings are process configuration, not mutable actor state. These +include SQLite implementation details, cache storage and byte limits, package +download egress policy, preload coordinator location, preload deadlines, actor +transport limits, sidecar executable selection, and logging. + +## Core-only public MVP surface + +The hosted action list below is deliberately smaller than embedded Core. These +operations remain available to trusted Core callers and are never exposed as +actor actions: + +| Core method or config | Why it is Core-only | +| --- | --- | +| `runtime.create` / `runtime.start` | RivetKit owns actor creation | +| `runtime.configure` | The actor exposes durable whole-document `config.set` | +| `runtime.dispose` | RivetKit owns actor shutdown | +| `filesystem.mount` / `filesystem.unmount` | The actor changes its whitelisted mount list through `config.set` | +| `process.kill` | Actor clients use `process.signal` with `SIGKILL` | +| `network.httpRequest` | Low-level primitive beneath actor-safe VM-port fetch actions | +| trusted `software.install(Path)` | Hosted software sources are URL-only | +| host binding and custom filesystem configuration | These values are not serializable or safe actor input | + +Core and the actor both expose runtime status/restart, filesystem observation and +I/O, processes, terminals, contexts, language execution, VM-port fetches, +software install/uninstall/list, and process-command cron.

A + different package that collides on a projected package or command name is + rejected rather than replacing existing content implicitly. +3. **Private URLs:** durable config accepts stable HTTPS URLs. Expiring URLs and + renewable registry authentication remain follow-up registry work. +4. **Artifact signing:** the MVP relies on HTTPS plus the expected SHA-256 digest. + Signed release manifests remain follow-up work. +5. **Package format:** runtime packages use `.aospkg` v2 without agent metadata; + v1 support and documentation were deleted with no compatibility path. +6. **Preload source:** an operator baseline and the bounded observed hot set are + combined. Either source is advisory and may be stale. +7. **Preload ranking:** the coordinator uses a bounded recency-weighted exact map + with deterministic eviction, not a probabilistic sketch. +8. **Filesystem descriptors:** the hosted whitelist contains `default` and + `durable` roots plus `durable` mounts. Unknown backends and every + host path are rejected during config normalization. +9. **Event naming:** public events use dotted names. +10. **Binary transport:** RivetKit CBOR carries byte strings as `Uint8Array`; + generated outputs permit `number | bigint` for 64-bit values. +11. **Actor action limits:** every action family has its own bounded byte, item, + concurrency, replay, stream, process, or terminal policy. These limits are + independent of RivetKit's type-level action-count limit. +12. **Remaining adapters:** Eve and Flue use the generated sandbox-only client; + Gigacode and the stale agent/session harnesses were removed. +13. **agentOS bindgen schema:** the prototype is product-local, exports the Rust + action/event registry, and generates dotted nested TypeScript actions. A + generic RivetKit bindgen remains optional follow-up work. + +## Primary concerns + +- Deleting the TypeScript actor first intentionally creates a period where the + hosted product does not build. The branch stack and CI expectations must make + that explicit rather than masking it with a compatibility actor. +- The current actor owns significant output replay, terminal emulation, preview, + scheduling, dynamic mounts, and linked-software behavior. Each behavior must + move to the owning shared layer or a narrow Rust adapter; deletion alone is not + proof that Core already covers it. +- Core's local-path source must be impossible to construct through actor + deserialization. Sharing one source enum without a closed actor-specific DTO + would recreate the host-filesystem vulnerability. +- Arbitrary URL fetching in a trusted process creates SSRF and credential-leak + risk. The downloader needs strict scheme, redirect, egress, size, deadline, + ambient-credential, and logging policy even though package code itself remains + untrusted guest content. +- URL text is mutable and cannot be the content cache key. The first successful + installation must pin a digest so actor restart never silently upgrades bytes. +- Health cannot wait indefinitely for package acquisition. Required package failure + must be distinguishable from optional preload timeout, and both require + observable metrics and typed state. +- A single physical SQLite file can tempt cross-owner migrations. Adapter and + test boundaries must enforce namespace ownership from the first PR. +- Generated TypeScript types alone do not guarantee behavioral parity. Shared + protocol fixtures and cross-client conformance tests are still required. +- Removing ACP touches more than the actor package: protocol frames, sidecar + extensions, adapters, schemas, publish discovery, examples, docs, and CI can + keep dead functionality reachable unless absence is explicitly tested. +- The old `@rivet-dev/agentos-apps` package is already represented by the separate + `@rivet-dev/dynamic-apps` project.

Parsing and projection remain bounded trusted-Core code; +package executables run only inside the untrusted guest boundary. + +Installing packages from a path inside the guest/actor filesystem is deferred. +It may be useful later, but it is not needed to establish remote package +installation and would require a separate immutable-snapshot design. + +## Durable package state + +Creation config may include a bounded list of `RemotePackageSource`. +`config.set` adds full-list replacement in step 11. `software.install` and +`software.uninstall` are domain-specific mutations of that same durable desired +package set; they do not +create a second authoritative software database. + +When the caller omits `digest`, the first successful fetch computes it and the +actor persists the resolved URL, digest, size, and package id. From that point +the digest is pinned: + +- Step 09 cache hits reuse bytes by digest. +- A missing local copy may fetch the URL again but must reproduce the persisted + digest. +- Changed bytes at the same URL return a typed package-digest mismatch; they + never silently upgrade an existing actor. +- Installing the URL again explicitly may resolve new bytes and replace or add + them according to the package collision rules. + +`software.list` reports the live applied projection, not merely requested URLs. +`config.get` reports the complete durable desired sources and reconciliation +state. This distinction keeps pending or failed installation visible. + +## URL semantics + +The installed identity is the lower-case `sha256:<64 hex>` digest of the exact +artifact bytes.

Desired state is the durable authority. After a crash, startup +compares desired and applied revisions and reconciles again idempotently. + +## Creation behavior + +Actor creation accepts `AgentOsActorCreateInput { config? }`. RivetKit passes it +to `create_state` only on first creation. Invalid input aborts that creation with +the typed error thrown by the actor. + +The actor normalizes the supplied config, or an empty input, and stores the +complete result as revision 1. Once state exists, later `getOrCreate` input is +ignored by ordinary RivetKit state semantics. It is not compared with stored +config and never acts as an update. + +Creation state is necessarily synchronous, so initial URL resolution happens +during bounded Core boot. A successful boot pins the same verified resolution +metadata back into the durable revision without incrementing it. + +## Restart behavior is deferred + +This step identifies when a config requires runtime replacement and exposes that +fact through `config.get` and `runtime.status`. It does not define graceful +process draining, signals, terminal shutdown, or force-kill timing. Those +semantics are tracked as follow-up work. + +Until that follow-up lands, `runtime.restart` uses the existing bounded Core +runtime replacement primitive and reports failure accurately. No spec in this +series should imply stronger graceful-shutdown guarantees. + +If boot fails, preserve desired config, report failed reconciliation, and allow a +later corrected replacement or explicit restart. Do not silently fall back to +an old configuration while reporting success. + +## Health and readiness + +`runtime.status` and platform health expose: + +- Desired and applied revisions. +- Reconciliation state and restart requirement. +- Required software acquisition state. +- Optional preload state separately. +- Runtime generation and lifecycle state. +- Bounded typed issues with timestamps. + +`runtime.status.configState` reports `restart_required` while the old ready VM +continues serving actions, and its desired/applied revisions identify the exact +gap. `ConfigSnapshot` serializes this field as `state`. + +Readiness succeeds only when the desired revision is applied and its required +packages are present. It never waits indefinitely. Optional predicted preloads +have their own deadline and do not make an otherwise ready actor fail. + +## Implemented tests + +- Omitted replacement fields reset environment and timer policy to defaults. +- Explicit empty environment, `false`, minimum preview TTL, and a one-lease + preview policy remain distinct from omission. +- Preview-only replacement advances the applied revision without replacing Core. +- Core VM changes retain the old applied revision and report + `restart_required`. +- Environment and permission collections have explicit actor-bound limits. +- Resolved software snapshots round-trip through input while untrusted metadata + is discarded before resolution. +- Rust Core preserves explicit environment and timer policy, including explicit + empty/false values and the default base environment. +- The action registry includes `config.set`, and the complete actor unit suite + guards the URL-only and host-mount-free boundary. + +Step 14 must add real Rivet integration coverage for concurrent conditional +writes, process death between desired commit and apply, wake reconciliation, +and a forced replacement-boot failure. Those require a running actor database +and sidecar rather than a unit-only mock of durable state. + +## Acceptance criteria + +- Creation and mutation use one versioned input type and normalization + implementation, which delegates VM validation to Core. +- `config.set` replaces one complete normalized desired document. +- Omitted properties reset to defaults; no field or array is incrementally + patched. +- Software install/uninstall are bounded exact-set operations over that same + desired document, not a second package state store. +- Desired config and its revision survive every actor/process restart. +- Optimistic concurrency prevents silent overwrite when callers opt into it. +- Core owns VM defaults and validation. The actor owns only its hosted security + boundary and recognizes its own preview-only live policy; all changed Core VM + fields conservatively require replacement. +- Every committed revision is either applied or visibly failed/pending. +- Actor health distinguishes required package work from optional preloading. + +## Dependencies and follow-up + +Depends on all feature layers through step 10 so the reconciler can classify the +whole config.

RFC 6902 path operations and + Kubernetes strategic/server-side apply are not exposed. +- Cron stays internal to the hosted actor and uses RivetKit's durable scheduler. +- Network response streaming remains bounded pull-based for this version. +- The hosted actor never accepts host filesystem paths or host mounts. +- The hosted actor defaults to an ephemeral VM root. Durable filesystems are + explicit whitelisted `durable` roots or mounts; actor state itself uses + the RivetKit SQLite adapter independently of that filesystem choice. +- Actor-owned, Core-owned, and filesystem-owned schemas share Rivet SQLite but + retain independent migration tables and namespaces. +- The local SQLite proof-of-concept is a merge blocker. The hosted actor must + use the production Rivet SQLite adapter before this stack is ready. +- Existing inspector capabilities that still apply are ported as an independent + consumer of the public actor actions and events. + +## Public configuration contract + +### Actions + +| Action | Meaning | +| --- | --- | +| `config.get` | Return the normalized desired config and revision state. | +| `config.set` | Replace the entire config document. Omitted fields select defaults. | +| `config.patch` | Apply an RFC 7386 merge patch to the current desired config. | + +Both mutations accept `expectedRevision`. A stale conditional mutation fails +without modifying durable state. All config-changing paths, including software +install and uninstall, go through one serialized mutation primitive: + +```text +mutate_config(expected_revision, mutation) + -> load current normalized desired config + -> verify revision + -> apply replace, merge patch, or typed mutation + -> normalize and validate with the sidecar-owned policy + -> resolve remote package sources + -> persist one next revision + -> classify live versus restart-required changes + -> reconcile actor and VM status +``` + +`config.set` treats its input as a complete input document. Every missing field +is reset to its default. `config.patch` follows these rules: + +- A missing object member is unchanged. +- A non-null value replaces the member. +- An object value recursively merges into an object member. +- `null` removes the member from the input document, which selects the default + when the document is normalized. +- Arrays replace atomically. They are never merged by index or identity. +- Unknown fields fail validation. + +For example, patching `{ "environment": { "DEBUG": "1" } }` preserves other +environment keys because `environment` is an object. Patching +`{ "software": [...] }` replaces the whole software array. Patching +`{ "limits": null }` resets limits to the sidecar defaults. + +### Why this differs from Kubernetes + +Kubernetes supports JSON Merge Patch, JSON Patch, strategic merge patch, and +server-side apply because many independent field managers mutate large shared +resources. agentOS has one trusted config owner and revision-checked writes. +RFC 7386 plus full replacement covers the useful cases without path escaping, +array merge keys, field ownership, or conflict metadata. + +### Defaults and desired state + +The sidecar owns VM defaults and runtime validation. Actor and embedded clients +do not copy sidecar default constants; some empty-list fields are sent +explicitly. The actor normalizes its hosted-only shape and persists the desired +document without materializing sidecar defaults. For a running VM, restart +classification asks the serving sidecar to compare resolved VM creation policy +for an explicit whitelist of runtime fields. Software sources, hosted +filesystem policy, and any future unmapped fields remain actor-owned +replacement-triggering comparisons. + +`config.get` reports desired configuration. `vm.status` separately reports the +running generation, applied revision, readiness, package warming, and issues. +A valid desired update may therefore be durable while the current VM still +reports `restartRequired`. + +## VM lifecycle terminology + +The public actor surface uses: + +- `vm.status` +- `vm.restart` +- `vm.booted` +- `vm.shutdown` +- `vm.limitWarning` + +Examples, integrations, generated types, and docs use VM for the guest +environment. Existing package names or third-party APIs that already contain +`sandbox` are not renamed by this step. + +## Process and terminal API + +### Simplified process surface + +| Current action | 0.4 action | Decision | +| --- | --- | --- | +| `process.exec` | removed | Shell-string execution is ambiguous and injection-prone. | +| `process.execFile` | `process.run` | Structured executable plus argv, with captured output. | +| `process.spawn` | unchanged | Structured executable plus argv, returning a live process. | +| `process.kill` | removed | Use `process.signal` with `SIGKILL`. | +| `process.readOutput` | `process.output.read` | Nest output replay under the output resource. | +| `process.writeStdin` | `process.stdin.write` | Nest stdin mutation. | +| `process.closeStdin` | `process.stdin.close` | Nest stdin mutation. | +| `process.resizePty` | `process.pty.resize` | Nest PTY mutation. | + +`exec` and `execFile` are inherited Node.js terms with a dangerous distinction: +`exec` commonly means shell parsing while `execFile` commonly means direct argv +execution. That distinction is easy for both people and generated code to miss. +It also duplicates `spawn`, encourages concatenated shell strings, and makes +quoting platform-dependent. `run` is the captured structured operation; +`spawn` is the live structured operation. A caller that intentionally needs a +shell runs `sh` with explicit arguments. + +The complete process groups are: + +```text +process.run +process.spawn +process.get +process.list +process.tree +process.wait +process.signal +process.stdin.write +process.stdin.close +process.output.read +process.pty.resize + +terminal.open +terminal.list +terminal.wait +terminal.close +terminal.stdin.write +terminal.output.read +terminal.pty.resize +``` + +### Unified replay + +Process and terminal output use the same bounded sequenced replay model: + +- monotonically increasing cursor within one VM generation; +- `after`, `maxEvents`, and `maxBytes` request bounds; +- a response containing events, next cursor, truncation/gap state, and terminal + end state; +- events are hints for low latency, while replay is authoritative for recovery; +- cursors from a stale VM generation fail with a typed `stale_generation` error. + +The event names are `process.output`, `process.exit`, `terminal.output`, and +`terminal.exit`. Separate terminal stdout/stderr event schemas should only exist +if the PTY implementation can actually preserve that distinction. + +## Pull and event inventory + +### Pull-based APIs + +- `process.output.read` +- `terminal.output.read` +- `network.fetchStream.read` +- `process.wait` +- `terminal.wait` +- all `get`, `list`, `status`, `tree`, snapshot, filesystem read, and config + observation actions + +`network.fetchStream.read` is a bounded blocking pull, not a log poll. It waits +up to a configured duration for the next response chunk and returns data, EOF, +or timeout. This avoids one actor event per network chunk and gives callers +explicit backpressure and cancellation. + +### Events + +- `vm.booted` +- `vm.shutdown` +- `vm.limitWarning` +- `process.output` +- `process.exit` +- `terminal.output` +- `terminal.exit` +- `cron.fired` + +Events provide low-latency notifications. Durable or bounded pull APIs remain +the recovery path after disconnects, dropped subscriptions, or inspector +reloads. + +## Cross-surface consistency + +The implementation must also standardize: + +- every action input as an object, including empty input objects; +- identifier field names and handle shapes across get/list/wait/mutation calls; +- one cursor/page envelope for bounded list and replay results; +- explicit byte and millisecond unit suffixes; +- one structured exit status across process, terminal, cron, and events; +- one mutation result envelope for config and software changes; +- one typed error taxonomy, including `invalid_input`, `limit_exceeded`, + `revision_conflict`, `stale_generation`, `not_found`, and `not_ready`; +- shared network request/response DTOs where `network.fetch` and embedded + `httpRequest` have equivalent semantics; +- the distinction between desired config and applied VM status. + +Language namespaces remain separate because their workflows are intentionally +different across JavaScript, TypeScript, and Python. + +## Contract generation and compatibility + +The agentOS bindgen remains a product-local prototype. It exports Rust DTOs, +the action/event registry, and contract metadata, then generates types for a +normal RivetKit actor handle. RivetKit itself is not modified by this step. + +The exported contract includes: + +- `apiVersion`, initially `https://rivet.dev/agentos/v1alpha1`; +- `contractMajor`, initially `1`; +- `contractHash`, derived deterministically from the canonical public contract; +- `capabilities`, including pull streaming, config merge patch, inspector + resources, and supported language namespaces. + +During alpha, actor and generated package ship in lockstep and may break +together. After `v1`, additions are compatible within major 1 and breaking +changes require major 2. If two majors must overlap, register versioned actor +implementations internally. Do not add a REST facade only for versioning. + +Future native RivetKit action streaming can back a newer client API while the +actor keeps the existing pull actions for a deprecation window. Transport +improvements therefore do not force an immediate public contract break. + +## Actor action limits and large payloads + +The actor documentation must state, in one table, the effective limits for: + +- encoded action request and response size; +- single and batch filesystem reads/writes; +- recursive directory listing and export; +- network request/response bodies and stream chunk size; +- process argv, environment, stdin, captured output, replay bytes, and wait + durations; +- terminal input, replay, and lifetime; +- language source, files, values, dependency requests, and results; +- software package count, compressed/uncompressed bytes, download duration, + redirects, and cache capacity; +- config size, action concurrency, previews, cron jobs, and event retention. + +Every actor action stays below the RivetKit action payload limit. Batch methods +must account for the whole encoded envelope, not only individual entries. Large +files and exports remain bounded for 0.4; a shared backpressured streaming +transport is a separate design rather than a larger action limit. + +## Software installation, cache, and preloading + +The hosted actor accepts only remote URL package sources. Embedded Core may +also accept a trusted local path. Both resolve to an immutable `.aospkg` +identity before projection under `/opt/agentos`. + +`software.list` reports packages currently installed in the running VM. +`config.get` reports desired package sources, even when the VM is unavailable. +`software.install` and `software.uninstall` are typed config +mutations and use the same revision, normalization, persistence, and +reconciliation path as `config.set` and `config.patch`. + +The process cache uses digest identity, single-flight downloads, a byte-bounded +LRU, generation pins, temp-file cleanup, and bounded usage observations. A +central preload coordinator stores only a low-frequency popularity hint. Each +process reads it once at startup and coalesces refreshes per process. + +Required configured packages must resolve before the VM becomes ready. +Optional advisory preloading runs under a fixed timeout. At timeout: + +- completed cache entries remain available; +- optional downloads with no required waiter are cancelled and partial temp + files are removed; +- required downloads continue to determine readiness or fail startup; +- the VM continues startup once required packages are ready; +- timeout counts and affected package identities are logged and measured. + +Production completion also requires persistent cache recovery, a minimum free +disk reserve, crash cleanup, cancellation tests, cache/preload metrics, +coordinator deployment, and capacity tuning. + +## Rivet SQLite and schema ownership + +The hosted actor uses the RivetKit SQLite API, never an actor-local SQLite file. +The per-VM database is physically shared while schemas remain independently +owned: + +- filesystem: `agentos_fs_*` and `agentos_fs_schema_version`; +- sidecar/Core: `agentos_core_*` and `agentos_core_schema_version`; +- static actor: `agentos_actor_*` and `agentos_actor_schema_version`. + +Every owner has an append-only migration ladder and updates its version in the +same transaction as its schema mutation. All agentOS-owned tables are +`STRICT`. No owner reads or advances another owner's migration table. The old +shared component-version mechanism and local hosted runtime database are +removed without compatibility aliases or dual writes. + +## Cron correctness + +Cron remains a hosted-actor concern. Public actions validate and serialize a +bounded `process.spawn` descriptor into RivetKit's durable scheduler. The +private invoke action is absent from generated public types. Invocation checks +the config revision, launches through the same process path as the public +action, and emits one bounded `cron.fired` event with either a process handle or +a typed launch error. The actor does not add a second parser, wakeup loop, or +cron database. + +## Inspector + +Port the applicable inspector views as a separate consumer of the generated +actor contract: + +- filesystem browser and mount inspection; +- process tree, status, output replay, signals, and stdin; +- terminals and terminal replay; +- installed software and package state; +- desired config, VM status, issues, limits, warnings, and restart; +- previews and networking status. + +The tabs may reuse existing UI components, but their data access moves to the +public actor actions/events. Do not port agents, sessions, ACP, prompts, +adapters, TypeScript actor hooks, host mount editing, or private actor internals. + +## Documentation + +Update existing quickstart, filesystem, process, network, software, resource +limit, permission, persistence, architecture, Rivet Actor, Eve, and Flue docs. +Add or consolidate pages for: + +- hosted actor API limits; +- pull transport, events, replay, and future streaming; +- configuration replacement, merge patch, defaults, and revision conflicts; +- software installation, cache, and preload architecture; +- contract versioning and generated RivetKit types; +- VM lifecycle, generations, status, and restart; +- hosted actor versus embedded Core; +- agentOS 0.4 migration; +- inspector capabilities. + +## Implementation checklist + +### Contract and configuration + +- [x] Add `config.patch` with RFC 7386 semantics and focused object, null, and + array tests. +- [x] Route set, patch, install, and uninstall through one revision-checked + mutation engine. +- [ ] Move shared defaults, validation, normalization, and change + classification to one sidecar-owned implementation. + The serving sidecar now compares resolved VM creation policy for + whitelisted fields on running VMs; actor-owned software/filesystem policy + and future fields remain local. Full normalization + ownership and no-running-VM comparison still need consolidation. +- [x] Keep generated clients free of copied runtime defaults. +- [x] Keep `config.get` desired state distinct from `vm.status` applied state. + +### Names and action shape + +- [x] Rename public `runtime.*` actions and events to `vm.*`. +- [x] Replace `process.execFile` with `process.run` and remove `process.exec`. +- [x] Nest process stdin, output, and PTY actions. +- [x] Align terminal stdin, output, and PTY action names with process actions. +- [ ] Standardize all action inputs, IDs, units, result envelopes, and typed + errors. Process `startedAt` is now `startedAtMs`, process tree timestamps + are `startTimeMs`/`exitTimeMs` with a structured `exit` and an optional + controllable process handle. Process forests now use raw kernel identity + internally so display-PID collisions cannot attach children to the wrong + actor handle; inspector expansion uses handle identity where available. + Hosted file metadata, installed software, and resolved package sources + use `sizeBytes`; list envelopes and remaining cross-action consistency + still need an audit. Expired fetch-stream handles and required package + resolution deadlines now map to typed `expired` and `timeout` errors. + Process argv now preserves valid empty elements; empty commands/CWDs are + `invalid_input`, while oversized strings are `limit_exceeded`. Terminal + CWDs use the same validation; DTO round trips and argument count/UTF-8 + byte boundaries have focused regression coverage. The sidecar preserves + an empty `sh -c` script when adding a non-root CWD prefix, without + dropping empty positional arguments. +- [x] Regenerate the TypeScript contract and update type tests, examples, and + integrations. + +### Replay, transport, and limits + +- [x] Implement one generation-scoped replay envelope for process and terminal + output. +- [x] Preserve bounded pull semantics for network response streams. +- [x] Document actor payload, time, concurrency, retention, and resource + limits in the hosted-actor limits reference. +- [x] Test aggregate batch/action bounds and stale-generation cursors. + +### Compatibility metadata + +- [x] Export `apiVersion`, `contractMajor`, deterministic `contractHash`, and + capabilities. +- [x] Exclude private actions from the public type tree and hash. +- [x] Add deterministic-generation and compatibility-policy tests. + +### Storage and scheduling + +- [x] Replace every hosted local SQLite path with the production Rivet SQLite + adapter. +- [x] Verify the three independent strict schema namespaces and transactional + migrations. +- [x] Remove temporary SQLite wording, configuration, and follow-up items. +- [x] Verify cron uses RivetKit durability only and private invocation is + revision-safe, bounded, observable, and absent from public bindings. + +### Trusted VM configuration + +- [x] Keep guest permissions active while trusted creation, mount updates, + package projection, and host-binding registration run. Operator-only + kernel paths preserve mount and command validation, bounded command + discovery, and empty mountpoint cleanup without exposing a guest-callable + bypass. Focused tests cover guest denial, mount errors, directory limits, + failed command-stub publication, and preservation of profile commands. +- [x] On a failed final permission write, restore the original policy or + fail closed to deny-all, and keep the stored VM policy in sync. + +### Software and preloading + +- [x] Route software mutations through the config mutation engine. +- [x] Verify cache single-flight, byte LRU, pins, cleanup, and cancellation. +- [x] Implement and test optional preload timeout behavior, including dropping + actor waiters and reporting pending package digests. Already-sent sidecar + requests use their remaining-time deadline; immediate cancellation of a + disconnected client waiter remains open below. +- [x] Add persistent cache recovery, free-disk reserve, crash cleanup, and + startup capacity controls; default to an isolated process-lifetime cache + when no per-worker persistent directory is configured. Standalone workers + clean these directories on normal shutdown or startup failure; forced + termination and host-crash leftovers require host temporary cleanup. +- [x] Export cache/preload metrics with fixed, bounded labels and worker-level + sampling. +- [ ] Verify coordinator deployment and capacity tuning with multiple actor + worker processes, including metrics-route access controls. +- [x] Document URL install, desired versus installed state, cache limits, + readiness, preload timeout, and failures. + +### Inspector and documentation + +- [x] Locate and port reusable filesystem, process, terminal, software, VM, + preview, and limits inspector tabs to the generated actor contract. + Terminal reattachment now pages within the actor's 256-event replay cap, + bounds the total repaint, and preserves sequence zero when the initial + snapshot is empty. Independent review preserved bigint cursors, detects + truncation/gaps, and deduplicates late live events. The process tab now + drains up to eight replay pages per poll and defers its exit marker until + backlog is consumed. Independent review bounds decoded page bytes, stops + drains on detail disposal, pins each drain to one actor, and preserves + UTF-8 across pages/polls and separate stdout/stderr streams. Terminal list + failures are visible without the removed legacy boot gate. Terminal IDs + are scoped to the captured actor handle across lookup and dispatch (33 + focused inspector tests pass, including actor switches and the shared + filesystem query-key test). +- [x] Remove agent/session/ACP and host-mount inspector surfaces. +- [x] Update public docs and navigation for the 0.4 actor API. +- [x] Ensure public docs consistently call guest environments VMs. + +### Validation + +- [x] Run actor unit tests and bindgen snapshot/type tests. +- [x] Run `cargo check --workspace` after the package-mount review fixes; + rerun after the process-snapshot, timer-wheel, and embedded process + lifecycle fixes. Warnings are pre-existing unused internal helpers. +- [x] Regenerate and check both Rust-derived TypeScript contracts; run the + bindgen tests (3/3), `pnpm build` (50/50), and `pnpm check-types` + (103/103) after the new limit field and again after the lifecycle fixes. +- [x] Run the limit inventory audit (5/5). The audit now classifies 467 + constants; 136 newly classified fixed ceilings remain deferred policy + work, not newly configurable limits. +- [ ] Run focused Core, example, integration, publish-helper, and docs tests + (client 66/66 before the latest focused process regression, example + type-checks, and publish 18/18 pass; opt-in live + SQLite/VM restart/cron and local SQLite/VFS checks pass; all native + sidecar test targets compile; Astra's kernel API 33/33 and focused native + 4/4 checks pass; Flue's hosted provider 5/5 and embedded native test pass; + latest sidecar package 4/4, configure-policy 2/2, and operator-unlink + 1/1 tests pass; Rust client process 8/8, actor process 5/5, TypeScript + collision 6/6, and TypeScript mount/RPC 7/7 tests pass; remaining runtime + and docs gates remain. The new package-mount service regressions (2/2), + operator unlink (1/1), projection (11/11), typed limits (8/8), and Rust + client limit serialization (1/1) pass). The full TypeScript Core unit + suite passes (20 files, 103 tests), as do the latest Rust client process + units (11/11), actor action-adapter units (8/8), and real-VM Node timeout + regression (including a bounded VM teardown). The native-sidecar-core + snapshot tests pass (4/4), along with the new kernel argv and timer-scope + regressions (1/1 each). The latest hosted actor library suite passes + (64 passed, 1 opt-in live test ignored), including the config classifier + and typed-error regressions. Astra's latest embedded Rust client suite + passes (77/77) with its contract-feature check and real-VM rejection/late + wait regression; TypeScript Core passes 114/114 with type checks. Final + runtime/docs gates remain. The full `pnpm test` run exposed a resolver + test that assumed no platform package existed above the workspace; its + isolated rerun now passes with deterministic package-resolution fixtures + and rejects mismatched or missing native binaries (7/7, including an + exact-version repair command). The next full + run exposed a stale `software/everything` test expectation for a removed + Codex package; its focused test now passes (2/2). A further full run + reached Core and exposed two pre-existing nested `npm test` hangs and + repeated VM SQLite-close errors. Both owned and internal VM disposal now + close capability admission after process drain, then close SQLite before + retiring blocking-job admission; a real local-DB + regression covers both paths, and an embedded smoke test no longer logs + the close error. The nested npm tests still time out in isolation with a + freshly rebuilt sidecar. Full-suite validation remains open. + The sidecar-resolved config comparison and session-owned wire dispatch + tests pass (2/2); the hosted actor suite passes 68/68 with one opt-in test + ignored. Astra's TypeScript protocol/transport comparison tests pass + (14/14), and all 103 workspace TypeScript type-check tasks pass after + this protocol change. The Rust Core default-feature build also passes + without the actor-only comparison helper. + Final workspace gates after Astra's fixes pass: `cargo check --workspace`, + `pnpm check-types` (103/103), `pnpm build` (50/50), + Rust client tests (78/78), `cargo fmt --all -- --check`, and fixed-version + verification. The later inspector/process-input pass also passes 33/33 + inspector tests, 71 actor library tests (one opt-in live test ignored), + 3/3 native shell-argument tests, `cargo check --workspace`, workspace + `pnpm check-types` (103/103), `pnpm build` (50/50), and formatting. + After protocol version 9 and the session acquisition review, the Rust + workspace check, protocol tests (8/8), native acquisition tests (4/4), + resolver/cache tests (19/19), TypeScript runtime-core protocol tests + (25/25), Core cross-language fixtures (7/7), workspace `pnpm build` + (50/50), workspace `pnpm check-types` (103/103), and formatting pass. +- [ ] Run `pnpm --dir website build` when the website checkout is available. +- [ ] Run `just docs-check-links` for changed routes and navigation. +- [x] Have an Astra reviewer inspect the complete diff, fix issues, and rerun + affected checks. A second Astra pass on the late process snapshot and + timer-wheel fixes added focused regression coverage. A further lifecycle + pass removed fabricated process exits in both embedded clients, fixed + normalized mount ordering, and added focused and real-VM regressions. + The latest Astra pass found and fixed package rejection type erasure, + missing TypeScript wire adapters, and unbounded sidecar acquisition + waiters; it also added protocol version 9 and timeout regressions. + +### Open implementation and verification work + +- Move VM config normalization, default materialization, and live/restart + classification out of the actor into one sidecar-owned contract. The actor + currently keeps optional runtime fields. For running VMs it now compares + resolved creation policy for whitelisted runtime fields through a + session-scoped sidecar request, so an explicit override equal to the + effective default does not force a restart. Software, hosted filesystem + policy, and future unmapped fields remain replacement-triggering. + When no VM is serving, it conservatively compares desired fields. The shared + VM config crate now bounds and canonicalizes Node builtin and loopback-port + overrides for the actor, embedded client, and sidecar; it rejects oversized + duplicate-heavy input before deduplication. The Rust embedded client sends + only explicit permission overrides at VM creation and leaves permissions + unset during boot and dynamic-mount configuration, matching TypeScript and + preserving the sidecar-resolved defaults; its copied network allowlist has + been removed. Actor restart classification now compares the complete desired + document except preview policy, so newly added fields are fail-safe until + deliberately classified. Ownership of the classification still needs to move + to the sidecar contract. Completing normalization ownership and an + independent no-running-VM comparison remains open. +- Preserve live software across dynamic mount changes. The sidecar now tracks + identities added by `LinkPackage` and composes them into later `ConfigureVm` + projections until an explicit `UnlinkPackage`; the TypeScript client no + longer mirrors them. Pinned packages retain their original projection roots; + conflicting IDs, package/command names, and normalized mount paths are + rejected before changing mounts. Regressions exercise link, mount add/remove, + custom-root retention, and unlink. Client-originated mount and software + mutations, including public `link_software`, share an async lock. + `ConfigureVm` still replaces other boot fields and all mounted leaves, so a + dedicated mounts-only operation and + cross-client reconfiguration semantics remain follow-up work. +- Make all VM configuration and package unlink mutations transactional or + define an explicit recoverable failure state. Replacement mounts are + preflighted for valid paths, registered plugins, duplicate paths, and + parseable plugin config. The mount phase now detaches old backends without + closing them, removes any replacement leaves on failure, and restores the + exact old backends. A failed package-link mount group also removes earlier + leaves before publishing package metadata. Rollback removes only newly + materialized empty mountpoint directories, before detaching their temporary + parents, preserving pre-existing underlying directories. Detached backends + are closed if abandoned, and attempted mount mutations invalidate usage + caches even on failure. Focused regressions cover malformed input, later + plugin-open and package-leaf failures, and directory preservation. Mount + setup and teardown sort by normalized path depth, including dot segments. + Remaining: roll back changes after the mount phase (command discovery/driver + registration, package runtime-state refresh, and bridge policy publication), + make package unlink's multi-mount and + empty-directory cleanup reversible, and define a recoverable state if any + rollback operation itself fails. The operator path preserves nonempty guest + directories, but that alone does not make unlink atomic. +- [x] Enforce an aggregate per-VM package mount limit, including runtime links + and `provides.files` leaves. `limits.agentosPackages.maxMounts` now defaults to + 4,096, can be raised, and is checked before mutating the live projection. A + near-limit warning and structured resource-limit rejection name the setting. + Capacity is checked while building the combined projection. Live accounting + uses installed mount paths, not a reread of mutable package sources; unlink + releases those paths without requiring spare capacity. Focused tests cover + boot, `provides.files`, dynamic link, source changes, unlink, and overrides. +- [x] Expose matching `tls` and `execution` limit groups in Rust Core, + TypeScript Core, and the generated actor contract. Serialization preserves + omitted sidecar defaults; focused tests cover wire names, invalid overrides, + and optional public types without duplicating runtime policy. +- Move package source resolution into the sidecar. The version 10 protocol has + a session-scoped `AcquirePackage` operation for config resolution and + preloading, a VM-scoped `InstallPackage` operation that verifies and pins + bytes before projection, and a session-scoped cache-stats operation. The + sidecar checks ownership before I/O. Rust Core now forwards a closed URL or + trusted-path source; the hosted actor accepts URLs only. The actor's required + installs, config resolution, advisory preload, and metrics all use the same + child-sidecar cache. Child cache settings are passed at process startup, and + the actor retains a pre-VM session until worker shutdown. Rust clients + preserve package-acquisition wire codes and rejection + metadata (including errno, retryability, and configuration paths) in a + dedicated typed error instead of misclassifying them as kernel failures. + Limits and timeouts retain their existing typed categories. The actor maps + invalid sources, formats, and digests to `invalid_input`; operator cache + configuration failures are not misreported as caller validation errors. + Public actor errors retain the package wire code and metadata under + `meta.package`. + The wire still lacks structured digest-mismatch fields, so it cannot safely + reconstruct every original local `ClientError` variant without parsing text. + - [x] Add a session-scoped sidecar acquisition operation so desired-only + config and advisory preload can resolve packages without a VM. + - [x] Move one bounded resolver/cache and its URL validation, digest checks, + single-flight admission, and eviction policy to the sidecar process. + The actor retains URL-only input policy and coordinator orchestration. + - [x] Make VM installation accept a closed URL/trusted-path source, derive + identity from verified bytes in the sidecar, and retain an artifact pin + until all package mounts are safely removed. Keep legacy trusted + directory linking distinct from verified `.aospkg` installation. + - [x] Start and configure the shared sidecar before worker preload; retain + its acquisition session while warm cache state is needed even with no + live VM. Remove actor-parent cache initialization to avoid two caches + or exclusive directory-lock contention. + The child is explicitly reaped before removing the worker's temporary + cache directory. The worker retains the sidecar handle before opening + the package session, so cancellation during session initialization + cannot hide a live child from shutdown cleanup. + - [ ] Finish the cancellation and cross-client parity audit. A dropped actor + waiter does not instantly cancel an already-sent sidecar request; + per-request remaining-time and operator timeouts bound it. Verify + shared-flight behavior for optional and required waiters, URL/path + digest identity, source mutation, pin/eviction lifecycle, and the + TypeScript Core install/list API. Local paths without an expected digest + now invalidate their source alias before every read, so replaced or + deleted bytes cannot be hidden while overlapping reads still + single-flight. Rust and TypeScript Core now admit only one local mount + or software mutation at a time and reject overlap with `invalid_state`; + neither client creates an unbounded waiter queue. Rust's + package-session/cache controls are hidden behind actor/sidecar + integration features rather than exposed as an unmatched Core API, and + both public Core installed-package DTOs use an explicit `sizeBytes` + field (`size_bytes` in Rust). The binary-level pre-VM child-cache test + passes, and the TypeScript Core now forwards install/uninstall and + returns isolated metadata snapshots. Focused Rust and TypeScript + concurrency regressions pass. +- [x] Make creation cancellation owned end to end. Explicit Core initialization + errors dispose a VM created earlier in the sequence. Rust Core runs + creation in an owned task; dropping the caller transfers the task to a + cleanup waiter that shuts down any late VM result. The actor likewise + keeps its creation task alive after its own deadline. A focused regression + covers detached Core task ownership; the actor library suite covers the + surrounding lifecycle state machine. +- The ignored Rivet SQLite driver probe passed against an already healthy, + isolated local engine: callback values, transaction rollback, and generation + claims all used the real RivetKit driver. The ignored standalone-actor test + passed VM restart with a new durable generation and an unchanged applied + config revision. Cold `rivetkit::test::setup` remains unreliable in this + workspace: it exits after 60 seconds with `wait for registry envoy startup: + channel closed`, including with isolated storage and the cached engine binary. +- The ignored standalone-actor test also passed durable cron schedule/list + across VM restart, cancellation, and a real scheduled invocation observed as + `cron.fired`.

Idle-VM slopes are 0.21 versus 0.22 MiB/VM. These figures include the +Node benchmark client and sidecar descendants. + +The original warm WASM regression (37.47 to 61.62 ms) was caused by rewriting the +same staged module on every launch, invalidating compilation warmup.

These results must not be presented as proof of +zero regression. The runtime keeps fresh image validation rather than trusting +an unchanged pathname as evidence of unchanged guest contents. + +The host runs unrelated background services, but this task ran no concurrent +builds or tests during measurement.

See the [Pipboy notes](../../scripts/pipboy/README.md). +- Full source footprint builds are explicit on PRs through `ci: full-footprint` + and still run on main pushes.

Executive decision + +AgentOS will refactor the boundary between the kernel, sidecar, and guest +executors before adding Wasmtime as a second standalone-WASM backend. + +- The kernel owns process identity, descriptors, VFS state, permissions, + signals, process groups, wait status, virtual sockets, PTYs, and resource + accounting. +- The sidecar owns runtime selection, external asynchronous I/O, the one Tokio + runtime, package resolution, lifecycle coordination, and host-visible events. +- Guest execution never runs on Tokio. Work that can wait uses async readiness; + unavoidable blocking work requires admission to the fixed bounded blocking + executor. No subsystem creates another runtime or blocks a Tokio worker. +- An executor owns only engine state, guest-memory/ABI adaptation, guest + scheduling, and engine-specific interruption mechanics. +- The kernel defines a runtime-neutral process-control contract. V8, Wasmtime, + Python, and binding executions expose control endpoints implementing that + contract; the kernel never imports concrete executor types. +- Executors consume capability-sized filesystem, network, process, terminal, + signal, clock, entropy, and identity services. They do not carry parallel + policy or resource tables. +- Every Linux/POSIX operation supported by AgentOS has one semantic + implementation in the kernel or its kernel-owned resource layer. Executors + adapt guest ABIs to that implementation; they do not provide per-engine + versions. +- Host operations stay in the existing kernel, execution, and sidecar crates. + The proven kernel/runtime/VFS accounting cycle is isolated in the small + runtime-neutral `agentos-resource-accounting` leaf crate described in Section 11. + +This is prerequisite architecture, not Wasmtime adapter work. The Wasmtime +executor specification depends on the exit gates in this document. All work in +this specification lands as one independent prerequisite JJ revision after the +specification/baseline revision and before any Wasmtime executor code. The +capability sequence in Section 12 is an implementation workstream order inside +that one revision, not permission to interleave Wasmtime or create one landing +revision per capability. + +### 1.1 Non-goals + +This refactor does not: + +- force JavaScript, WASM, and Python to expose the same guest API; +- move Node streams, WASI layouts, Python objects, or engine event loops into + the kernel; +- make the kernel own or poll executor instances; +- move external Tokio networking into the kernel; +- replace working kernel VFS/socket/PTY/process implementations; +- require every capability family to migrate in one atomic change; or +- compile, repair, or reactivate the browser runtime. + +The shared layer standardizes authority, state, typed operations, completion, +and control. Adapters remain free to expose language-appropriate APIs. + +### 1.2 Scope and parity target + +The scope is **feature parity or better with the complete currently supported +V8-hosted standalone-WASM environment**, not an abstract project to implement +every syscall ever shipped by Linux. + +The baseline includes: + +- every active `wasi_snapshot_preview1` and AgentOS `host_*` import; +- the owned patched Rust/libc/sysroot surface used by current software; +- commands and interactive programs that already work, including `ls`, `vim`, + `grep`, `curl`, shell/process pipelines, sqlite, and the registry command + suite; +- current filesystem, descriptor, networking, process, signal, TTY, identity, + clock, permission, and resource-limit behavior; and +- hostile raw modules that call imports directly without libc. + +If the current implementation has multiple engine-specific versions of one +operation, the refactor selects or builds one Linux-correct kernel +implementation and migrates all current executors to it. Correctness fixes are +in scope and may intentionally change existing V8 behavior. + +Future supported Linux APIs follow the same rule: add the semantic operation to +the kernel/shared resource owner first, then expose it through adapters. The +project is complete when the existing V8-WASM feature and software corpus runs +through this single implementation and Wasmtime can consume it without adding +semantic host code. + +### 1.3 Wasmtime research constraints on this refactor + +No Wasmtime spike is required, but the published embedding API imposes concrete +requirements that the shared boundary must satisfy: + +- Wasmtime's `Linker` can provide the existing AgentOS Preview1 and `host_*` + imports directly; the refactor must not assume `wasmtime-wasi` resource + ownership. +- Async host imports suspend a Wasmtime call as a future. The host service must + accept bounded owned values and return through an awaitable direct reply; + guest-memory borrows cannot cross the wait. +- Wasmtime does not provide the embedding's execution pool. The sidecar must + poll guest execution on the existing bounded non-Tokio VM executor while + Tokio owns external async I/O. +- A Wasmtime `Store` needs cloneable generation-bound handles to host services, + cancellation, readiness, limits, and the kernel process reporter. It cannot + own or mutably borrow the sidecar's `KernelVm`. +- Epoch interruption and Store cancellation need a thread-safe control handle + that maps naturally to the same kernel process endpoint used by V8. +- Compiled `Module` sharing and caching are engine concerns and must not affect + kernel process, fd, filesystem, or signal ownership. +- Shared-memory threads are not part of the initial parity target; the current + V8-WASM software surface is the first Wasmtime admission gate. + +These constraints are sufficient to design the kernel interface without +building a provisional Wasmtime implementation. + +## 2. Why this refactor is needed + +The current code already contains the beginning of the correct abstraction, +but it is not connected to the real executors. + +`agentos-vm-kernel` defines `DriverProcess`, stores an +`Arc` in every process-table entry, and owns blocked and +pending signal sets. However, `KernelVm::register_process` always registers a +`StubDriverProcess`. The stub records signals and synthesizes exits; it is not +the `ActiveExecution` actually running the guest. + +The sidecar separately stores: + +- `ActiveExecution::{Javascript, Python, Wasm, Binding}`; +- an additional signal-disposition map; +- an additional pending-WASM-signal set; +- V8-specific signal/session delivery; +- runtime pause, resume, termination, and OS-process signal logic; and +- readiness targets containing `V8SessionHandle`. + +This produces two process-control planes: + +```text +kernel ProcessTable + -> DriverProcess + -> StubDriverProcess + +sidecar ActiveProcess + -> ActiveExecution enum + -> V8 / Python / V8-WASM / binding-specific control +``` + +Signals generated by kernel operations such as `EPIPE`, child exit, or PTY +resize can therefore take a different path from signals delivered through the +sidecar. Wasmtime would add another path unless this boundary is fixed first. + +The same pattern exists in less concentrated form for fd aliases, filesystem +permissions, mutable rlimits, clocks, identity, terminal metadata, and socket +readiness. The semantic implementation is often already in Rust, but the +effective state or transport remains executor-specific. + +## 3. Required dependency direction + +The kernel must not own or depend on V8, Wasmtime, Pyodide, JavaScript bridge +types, Tokio tasks, or concrete sidecar process records. + +```text + kernel-owned durable state + process / fd / VFS / signal / PTY + ^ | + | | control wake + typed host services + | v +sidecar lifecycle + I/O ---- runtime-neutral execution contract + ^ + | + +----------------+----------------+ + | | | + V8 adapter Wasmtime adapter Python adapter +``` + +There are three distinct interfaces: + +1. **Kernel to executor:** nonblocking, coalesced process-control requests. +2. **Executor to host:** typed, bounded operations over kernel/sidecar + capabilities. +3. **Sidecar to executor:** start, event, exec-replacement, cancellation, and + teardown lifecycle. + +Combining these into one enormous `Executor` or `GuestHost` trait would couple +unrelated capabilities and recreate the current switchboard under a new name. + +## 4. Kernel-facing process runtime endpoint + +### 4.1 Replace the stub-only driver connection + +Evolve `DriverProcess` into a narrow runtime endpoint registered with the +process-table entry: + +```rust +pub trait ProcessRuntimeEndpoint: Send + Sync { + fn request_control( + &self, + request: ProcessControlRequest, + ) -> Result<(), ProcessRuntimeEndpointError>; +} + +pub enum ProcessControlRequest { + Checkpoint, + Stop, + Continue, + Terminate(ProcessTermination), + Cancel(CancellationReason), +} +``` + +The exact names are not normative. The behavioral requirements are: + +- calls never execute guest code inline; +- calls never block a kernel lock or Tokio worker; +- standard-signal notifications are coalesced into durable kernel state; +- each execution has at most one queued wake; +- stop, terminate, and cancellation cannot be dropped because an ordinary + event queue is full; +- endpoint failure is typed and observable; and +- the endpoint contains no authority beyond its registered VM generation and + kernel PID. + +The endpoint implementation should be a cloneable control handle separate from +the owned engine instance. It may set atomic control bits, request a Wasmtime +epoch interruption, interrupt a V8 session, notify an admitted VM-executor +thread, or signal a native child process. Those mechanics stay inside the +adapter. + +Process allocation and backend construction currently have a PID dependency in +both directions. Resolve it with a two-part control cell: + +1. the sidecar creates a bounded `RuntimeControlCell` and registers its producer + endpoint while the kernel allocates the PID; +2. the sidecar constructs the backend with that PID and attaches the one + consumer to the cell before starting guest instructions. + +Control requested during construction remains durable in the cell. A +termination requested before attachment prevents the guest from starting; no +temporary production stub and no lost-signal window are allowed. + +`StubDriverProcess` remains only for kernel unit tests and deliberately virtual +processes. Production guest processes register their real runtime endpoint. + +### 4.2 Executor-to-kernel exit reporting + +Do not retain `DriverProcess::wait` as a second source of process status. The +kernel process table is authoritative for wait and zombie state. + +At registration, the sidecar receives a generation-bound reporter capability: + +```text +report_exit(Exited(code)) +report_exit(Signaled { signal, core_dumped }) +report_runtime_fault(typed_error) +``` + +Reporting is idempotent and first-terminal-result wins. The kernel records the +exit, closes or releases process resources through the existing lifecycle, +creates `SIGCHLD`, wakes waiters, and exposes exact signal metadata. An exit +code of `128 + signal` is never used to infer that a signal occurred. + +Kernel-wide termination requests control through every endpoint and then waits +on process-table terminal state with bounded grace and kill phases. It does not +call an endpoint-specific `wait` method, because that would restore a second +source of process status. + +## 5. Kernel-owned signal model + +Signals should be handled at the kernel level. The current kernel owns only +part of the state; the refactor completes that ownership. + +### 5.1 Authoritative state + +Each kernel process owns bounded signal state: + +- disposition for signals 1 through 64: default, ignore, or user; +- disposition flags and handler mask, but not a guest function pointer; +- blocked signal set; +- coalesced pending standard-signal set; +- running, stopped, and exited state; +- bounded in-progress delivery tokens needed for nested handlers; and +- exact terminating signal and core-dump metadata. + +Guest handler pointers remain inside V8 or WASM linear memory and are never +kernel capabilities. A `user` disposition means the adapter must deliver the +signal at a guest safe point. + +`sigaction`, `sigprocmask`, `sigpending`, signal generation, exec disposition +reset, and wait-state changes all operate on this one record. The sidecar +`signal_states` map and `ActiveProcess.pending_wasm_signals` are deleted. + +### 5.2 Delivery decision + +`signal_process` performs Linux-compatible target validation and then makes the +delivery decision while holding the process-table state: + +- signal 0 validates only; +- a blocked catchable signal becomes pending; +- an ignored signal is discarded, except for required `SIGCONT` resume + behavior; +- a caught signal becomes pending and requests `Checkpoint`; +- a default stop signal changes kernel status and requests `Stop`; +- `SIGCONT` changes kernel status and requests `Continue` before any caught + handler runs; +- a default terminating signal requests `Terminate`; and +- `SIGKILL` and `SIGSTOP` cannot be blocked, ignored, or caught. + +Kernel-generated `SIGPIPE`, `SIGCHLD`, and PTY foreground-group `SIGWINCH` use +this exact path. The sidecar does not generate duplicates. + +### 5.3 Guest handler checkpoint + +At a safe point, an adapter asks the kernel to begin one pending delivery. The +kernel atomically selects an unblocked signal, applies `sa_mask`, +`SA_NODEFER`, and `SA_RESETHAND`, and returns a bounded delivery token plus the +signal number and flags. The adapter invokes its guest handler and then closes +the token so the previous mask is restored. + +For WASM, the owned libc calls `__wasi_signal_trampoline`. For Node/V8, the V8 +adapter schedules the matching process signal event. The kernel does not call +either engine. + +An interruptible host operation registers its waiter and temporary `ppoll` +mask atomically with the signal state. A caught signal wakes the operation and +returns `EINTR` or a restart checkpoint. Ignored and still-blocked signals do +not spuriously interrupt it. + +`SA_RESTART` requires one documented, shared set of restartable operations. +Before real threads, the mask is process-scoped. The later threads project +moves masks and in-progress delivery stacks to kernel thread records without +changing executor control. + +## 6. Sidecar-facing execution backend contract + +`ActiveExecution` currently implements common behavior through a growing enum +match and also exposes V8-specific session and sync-RPC methods. Replace that +surface with a small common backend contract and adapter-owned extensions. + +The common lifecycle is: + +```rust +pub trait ExecutionBackend { + fn runtime_kind(&self) -> GuestRuntimeKind; + fn control_endpoint(&self) -> Arc; + fn start_prepared(&mut self) -> Result<(), ExecutionError>; + fn poll_event( + &mut self, + cx: &mut Context<'_>, + ) -> Poll, ExecutionError>>; + fn begin_shutdown(&mut self, reason: ShutdownReason) + -> Result<(), ExecutionError>; +} +``` + +This is an architectural shape, not a requirement to use `async_trait` or +dynamic dispatch. An enum may remain as storage if all common callers use the +contract and engine-specific matches are confined to construction/adapters. +The owned backend is deliberately not required to be `Send`: V8 remains +thread-affine on its admitted VM-executor thread. Only its control and wake +handles cross threads. + +Common events are bounded and runtime-neutral: + +```text +stdout(bytes + reservation) +stderr(bytes + reservation) +host_call(typed request + direct reply handle) +warning(typed warning) +exited(process termination) +``` + +A host-call event carries its response capability. Shared code must not call +methods such as `respond_javascript_sync_rpc_*` on the execution enum. Python +VFS requests, V8 synchronous bridge calls, and Wasmtime async imports normalize +to the same typed host operations where their semantics are shared. + +V8-only stream events and Node-specific callbacks remain adapter extensions; +their types do not appear in filesystem, process, signal, or readiness owners. + +## 7. Executor-facing host services + +The executor-facing API is split by capability rather than engine: + +```text +GuestFileHost paths, descriptors, metadata, directory operations +GuestNetworkHost sockets, DNS, connect/listen/data/options/readiness +GuestProcessHost spawn, exec, wait, groups, rlimits, descriptor actions +GuestTerminalHost PTYs, termios, window size, foreground group, stdio +GuestSignalHost sigaction, masks, pending delivery checkpoints +GuestIdentityHost uid/gid/groups and passwd/group lookup +GuestClockHost realtime, monotonic time, timers +GuestEntropyHost bounded random bytes +``` + +These are typed operation families, not necessarily Rust async traits. The +initial implementation can use bounded request messages with direct reply +handles because the sidecar owns mutable `KernelVm` and the process-wide Tokio +reactor. The requirements are: + +- request inputs are owned, bounded values; +- the caller supplies only VM generation, kernel PID, and registered + capability identity—not authority chosen by guest bytes; +- replies carry typed `{ code, message, details }` errors; +- every async request has one registered waiter and cancellation path; +- no synchronous waiter scans or consumes unrelated execution events; +- overload is a typed limit error, never an infinite retry loop; +- kernel operations remain the semantic and permission authority; and +- external OS I/O remains in sidecar runtime services, not the kernel crate. + +### 7.1 Async and blocking execution contract + +Synchronous guest semantics do not authorize blocking a Tokio worker. Every +operation is classified by where work executes and how it waits: + +| Work | Owner | Waiting rule | +| --- | --- | --- | +| V8, Wasmtime, Python, or binding guest instructions | Bounded non-Tokio VM executor | May occupy only its admitted VM-executor capacity; never polled or entered synchronously by Tokio | +| Bounded in-memory kernel operation | Kernel called by sidecar host service | May execute inline only when it cannot wait and has a bounded work quantum | +| Kernel fd read/write/poll that would block | Kernel readiness plus sidecar waiter | Return readiness/`EAGAIN` state and suspend the guest operation; never wait on a condvar or blocking channel on Tokio | +| Native TCP/UDP/Unix/TLS/DNS and timers | One process-wide Tokio runtime | Use async I/O, bounded commands, direct completion waiters, and cancellation | +| Unavoidably blocking host filesystem/library work | Fixed bounded blocking executor | Acquire admission before submission; bounded queue and deadline; never use Tokio's elastic blocking pool as unbounded admission | +| Guest-visible sleep, child wait, terminal input, and record locks | Durable kernel/sidecar wait registration | Suspend until readiness, signal, timeout, cancellation, or teardown; no polling timer and no executor-specific child pumping | + +The process contains exactly one Tokio runtime. No VM, executor, socket, +filesystem adapter, or child process creates another runtime. No code running +on a Tokio worker may use `block_on`, `Atomics.wait`, a condition-variable wait, +a blocking channel receive/send, synchronous guest entry, or an unadmitted +blocking syscall. + +An asynchronous host call follows this sequence: + +1. The guest adapter validates and copies bounded owned input. +2. It submits a typed request with a registered direct reply handle and + cancellation identity. +3. The Wasmtime/V8/Python execution yields or parks only its admitted + non-Tokio execution context. +4. The sidecar performs bounded kernel work, starts async Tokio I/O, or admits + unavoidable blocking work to the fixed blocking executor. +5. Completion settles only the registered waiter, updates durable readiness, + and enqueues at most one coalesced execution wake. +6. The guest adapter resumes, revalidates guest memory if applicable, and + encodes the typed result. + +Every path has explicit limits for request count, request bytes, retained +buffers, outstanding waiters, blocking jobs, and completion bytes. Cancellation +and VM teardown settle or fail every waiter; fire-and-forget work that can lose +an error is prohibited. + +The V8 RPC decoder and Wasmtime linker are two transports into these same +operations. A transport may decode a different ABI, but it may not implement a +second fd table, signal state, network policy, or filesystem permission model. + +## 8. Filesystem and descriptor requirements + +The kernel fd table is the only authoritative guest descriptor namespace. +Kernel state owns open descriptions, offsets, flags, rights, cwd/path-at +resolution, preopen metadata, filesystem permission tier, rlimits, and errno. + +The current sidecar contains a bidirectional mutable shadow filesystem: +some embedded-Node operations write host paths, sidecar calls copy those paths +into the kernel, kernel mutations are mirrored back to host paths, and exit-time +walks reconcile them again. This exists because parts of the V8/Node filesystem +and module loader still access a materialized host tree. It can resurrect stale +files, requires a second inventory, duplicates permissions/metadata, and makes +the source of truth timing-dependent. + +That mechanism is migration debt. It is not part of the shared host service and +is not inherited by Wasmtime. + +Current evidence is concentrated in +`crates/vm/src/filesystem.rs`: `guest_filesystem_call` invokes +`sync_guest_filesystem_shadow_before_call` and +`mirror_guest_filesystem_shadow_after_call`; `ProcessModuleFsReader` reads the +process shadow before the kernel; and launch/exit paths call +`sync_process_host_roots_to_kernel`. The managed WebAssembly path already +prefers kernel filesystem RPCs when its execution root is configured, so this +mirror is primarily embedded-runtime compatibility debt rather than a Wasmtime +requirement. + +The target has one mutable source of truth: + +- all guest filesystem operations, including embedded V8 `fs`, module + resolution, WASI, Python, and wire filesystem calls, use `GuestFileHost` over + the kernel VFS and fd table; +- host-directory access occurs through explicit confined kernel mount/plugin + resources, not by copying a directory tree into and out of the VFS; +- `/opt/agentos` package projection means kernel/VFS mounts of immutable package + resources, not a mutable shadow copy; +- a module loader may cache immutable bytes under ordinary bounded cache rules, + but it cannot maintain writable filesystem state outside the kernel; and +- an executor may stage one immutable, kernel-authorized executable image into + VM-private scratch storage when its engine requires a host path. That staging + is a one-way engine input: it is generation-bound, is not exposed as guest + filesystem state, is never consulted for later path or module resolution, + and is never reconciled back into the kernel VFS; +- V8 may temporarily retain an ABI fd-alias map while Node-WASI is migrated, + but aliases resolve to kernel descriptors and cannot own offsets, rights, + contents, or lifecycle. + +Cutover requirements include: + +- remove mutable host-shadow reconciliation, including shadow inventories, + pre-call host-to-kernel sync, post-call kernel-to-host mirroring, and exit-time + tree walks; +- route embedded V8 filesystem builtins and module reads to the kernel-backed + service before declaring the prerequisite complete; +- raw `host_fs` calls cannot bypass the configured filesystem tier; +- absolute paths and dirfd-relative paths share kernel resolution; +- preopens and descriptor rights come from kernel metadata; +- mutable `RLIMIT_NOFILE` moves into kernel process state; +- descriptor allocation has one limit and warning path; and +- kernel errors cross the sidecar as typed values instead of strings. + +## 9. Network and readiness requirements + +The kernel remains the owner of virtual socket state and the sidecar remains +the owner of external TCP/UDP/Unix/TLS transports. + +Replace `V8SessionHandle` readiness targets with a generation-bound +`ExecutionWakeHandle`. Readiness is durable level state in the resource owner; +the wake is only a coalesced hint. Each execution has at most one queued wake, +and each in-flight operation has one direct completion waiter. + +The wake handle cannot: + +- clear readiness merely because an adapter consumed a hint; +- select another VM generation; +- enqueue unbounded packet/chunk events; +- run guest code on a Tokio thread; or +- own a second socket registry. + +V8 translates the wake into its event-loop checkpoint. Wasmtime wakes the +future polled by the bounded VM executor. Python uses the same operation and +readiness state rather than a polling timer. + +## 10. Process, terminal, identity, clock, and entropy requirements + +- Spawn and exec are sidecar lifecycle operations over kernel process/fd state. + Runtime selection is not an executor responsibility. +- Process file actions use kernel descriptors directly and preserve atomic + commit/rollback semantics. +- PTY state, line discipline, termios, foreground pgid, and window size stay in + the kernel. Host stdout ordering, raw-mode cleanup leases, and tracked-runtime + `SIGWINCH` wakes stay in the sidecar service. +- UID/GID/effective IDs, supplementary groups, umask, and mutable rlimits are + kernel process state. Executors do not reconstruct them from environment + variables. +- Realtime policy and monotonic process time come from a shared clock service; + Wasmtime and V8 do not use ambient engine clocks. +- Random reads validate the guest range first and use a bounded/chunked shared + entropy service backed by the same source as virtual `/dev/urandom`. +- Intentional Linux-compatibility stubs such as fixed identity mutation, + loopback-only interface enumeration, or unsupported `mlock` stay in the + owned sysroot and behave identically under both engines. + +## 11. Code organization + +Implementation exposed one real dependency cycle: the kernel and process +runtime both need the hierarchical reservation ledger, while VFS already +depends on the process runtime. The ledger therefore lives in the deliberately +small `agentos-resource-accounting` leaf crate. It contains no Tokio, VFS, executor, or +product dependency; kernel configuration remains the policy authority and the +runtime can only observe usage for telemetry. + +```text +crates/resource-accounting/src/ + lib.rs runtime-neutral ledger, reservations, change wakes + +crates/vm-kernel/src/ + process_table.rs authoritative process/signal/wait state + process_runtime.rs runtime endpoint, control requests, exit reporter + signal.rs dispositions and delivery checkpoints + +crates/executor-contract/src/ + backend/ + mod.rs common lifecycle/event contract + control.rs engine-side endpoint helpers + event.rs runtime-neutral bounded events/reply handles + host/ + mod.rs + error.rs + filesystem.rs + network.rs + process.rs + terminal.rs + signal.rs + identity.rs + clock.rs + +crates/vm/src/ + executor.rs concrete-engine composition and dispatch + execution/ + process.rs PID/generation lifecycle and event routing + host_dispatch/ + filesystem.rs kernel/mount-backed filesystem operations + network.rs kernel/native transport capability operations + process.rs + terminal.rs + signal.rs + identity.rs + clock.rs +``` + +The exact file split can follow the implementation, but these ownership +boundaries are normative. Do not put every operation in one `executor.rs`, one +`host.rs`, or one mega-trait. + +`agentos-executor-contract` is the proven shared contract boundary. A second +host-contract crate remains unjustified; implementation adapters stay in the +sidecar and concrete engine code stays in independently feature-gated executor +crates. + +## 12. Prerequisite-revision workstream sequence + +The entire sequence below is **one delivery phase and one JJ revision**. These +workstreams provide implementation and review checkpoints while the revision is +being developed. The revision is ready to land only when every workstream and +every Section 13 exit gate is complete. Local intermediate revisions may be +used while developing it, but they are folded before handoff. + +### Workstream 0: Freeze contracts and parity tests + +- Inventory every active Preview1 and `host_*` import and every owned-sysroot + extension used by the current software suite. +- Record signal, fd, process, terminal, network, errno, permission, async-wait, + and resource-limit behavior. +- Freeze the working V8-WASM command corpus, including interactive and + process/network-heavy programs, as the minimum parity suite. +- Add hostile raw-import tests for permission and ambient-host bypasses. +- Add exact exit-code-versus-signal assertions. + +### Workstream 1: Connect kernel processes to real runtime endpoints + +- Add `ProcessRuntimeEndpoint` and the generation-bound exit reporter. +- Register real control handles for V8, Python, binding, and compatibility + WASM executions. +- Remove production dependence on `StubDriverProcess`. +- Preserve current sidecar signal behavior temporarily behind the endpoint. + +### Workstream 2: Make signals kernel-authoritative + +- Move dispositions, masks, pending state, and exec reset into the process + table. +- Route `SIGPIPE`, `SIGCHLD`, PTY signals, kill, and process-group delivery + through one path. +- Add begin/end handler-delivery checkpoints and atomic `ppoll` masks. +- Delete sidecar and runner duplicate signal state. + +### Workstream 3: Introduce typed backend events and host calls + +- Add direct reply handles and typed errors. +- Stop routing shared operations through unrelated session-event scanning. +- Confine V8 sync-RPC details to the V8 adapter. + +### Workstream 4: Consolidate filesystem and descriptor authority + +- Move permission tier, preopens, fd rights, rlimits, and path-at resolution to + kernel process state. +- Implement the shared filesystem host service. +- Route embedded V8 filesystem and module loading through that service. +- Delete mutable host-shadow inventories and bidirectional reconciliation. +- Preserve host access only through explicit confined mounts/plugins. + +### Workstream 5: Generalize readiness and networking + +- Replace V8 session readiness targets with execution wake handles. +- Route V8, Python, and later Wasmtime through the same bounded operations and + direct waiters. +- Remove adapter-owned socket state that duplicates kernel/capability state. + +### Workstream 6: Finish process, terminal, identity, clock, and entropy services + +- Remove runner-local rlimits, identity, TTY caches, and clock/random providers. +- Complete live kernel termios, pgid, and supplementary-group operations. +- Close typed-error and Linux-conformance gaps. + +### Workstream 7: Close the prerequisite revision + +- Require new executors to implement only the common lifecycle/control + contract and the ABI adapter over shared host services. +- Start the Wasmtime implementation only after the complete current V8-WASM + ABI and software parity surface, including signal/readiness foundations, has + closed its exit gates. +- Do not build a separate Wasmtime spike or provisional semantic host layer. +- Verify that the final tree contains no Wasmtime executor implementation and + passes the complete current-executor parity suite before the next JJ revision + begins. + +## 13. Exit gates + +The prerequisite refactor is complete when: + +- every production kernel process has a real runtime endpoint; +- `StubDriverProcess` is test/virtual-process-only; +- the kernel process table is the only owner of signal dispositions, masks, + pending sets, process status, and wait events; +- kernel-generated and externally requested signals use one delivery path; +- filesystem permissions, fd rights, preopens, rlimits, identity, and umask are + authoritative kernel process state; +- no mutable guest filesystem state is synchronized between a kernel VFS and a + host shadow tree; +- embedded V8 filesystem calls and module resolution observe kernel state + directly; +- shared readiness targets contain no `V8SessionHandle`; +- common host services contain no `Javascript*`, `V8*`, `Wasmtime*`, or + `Python*` types; +- common sidecar code does not match an executor variant to perform signal, + filesystem, network, process, or terminal semantics; +- every request, reply, queue, waiter, and retained buffer is bounded and + accounted; +- kernel error codes cross the host boundary without string parsing; and +- V8, Python, and compatibility WASM pass the complete current V8-WASM ABI and + working-software parity suite through the new services before Wasmtime work + begins. + +## 14.

Phase 1 keeps the generated ABI manifest +and rebuilt-module import audit synchronized with that mapping. + +## 15. Principal risks + +| Risk | Severity | Mitigation | +| --- | --- | --- | +| A generic interface becomes a mega-trait mirroring `ActiveExecution` | High | Split lifecycle, control, events, and capability-sized host services. | +| Kernel calls guest code or blocks on an executor | Critical | Runtime endpoint only sets bounded/coalesced control state and wakes the admitted executor. | +| Signal state moves but remains duplicated during migration | Critical | Declare kernel state authoritative phase by phase; adapters become subscribers, not mirrors. | +| Endpoint queue saturation drops `SIGKILL`, stop, or cancellation | Critical | Durable atomic control state with at most one wake; no ordinary event queue for control. | +| Mutable V8 host shadows survive and remain a second filesystem truth | Critical | Migrate embedded V8 `fs` and module reads to `GuestFileHost`; delete shadow inventories and bidirectional sync before Wasmtime. | +| Host-operation traits hide unbounded allocation or waiting | Critical | Owned bounded request types, direct waiters, resource reservations, typed overload. | +| Kernel grows Tokio or engine dependencies | High | Keep external I/O and executor mechanics in sidecar/adapters; kernel contracts remain engine-neutral. | +| Large refactor blocks all feature work | High | Migrate one capability family at a time inside the prerequisite revision, keeping V8 parity at every workstream checkpoint. | + +## 16. Resolved owner decisions + +1. The kernel owns every executor-independent Linux/POSIX semantic operation, + including complete signal state and delivery decisions. +2. Production kernel processes register real runtime control endpoints; + `StubDriverProcess` remains test/explicit-virtual-process-only. +3. The parity target is the entire currently supported V8-WASM ABI and working + software surface, not a hand-picked Wasmtime subset and not every + theoretical Linux syscall. +4. Correctness, security, errno, and Linux-behavior fixes may ship during the + refactor even when they intentionally change current V8 behavior. +5. The browser runtime is entirely out of scope, including compile fixes and + migration gates. +6. `ActiveExecution` may remain a sealed enum behind the common contracts; + dynamic dispatch is not a project goal. +7. Mutable filesystem state has one source of truth in the kernel. Existing + host-shadow synchronization is removed rather than generalized. +8. No Wasmtime spike is built. Wasmtime implementation starts after the + prerequisite parity gates close and uses only the resulting shared services. +9. The complete runtime-neutral refactor is one independent JJ revision.

Its optional adapter features create conditional +Cargo edges to the separately packaged engines, but a no-feature VM build +links none of them and `agentos-vm` contains no V8, Wasmtime, Pyodide, or Node +implementation code. + +The sidecar selects concrete extensions, including ACP. `agentos-vm` retains +only the engine-neutral extension lifecycle and capability adapter because an +extension must operate on the same authoritative VM/process state as every +other host operation. This does not pull ACP, agents, prompts, or session +implementations into the VM crate. + +## 3. Package responsibilities + +### 3.1 `agentos-sidecar` + +`agentos-sidecar` is the only sidecar process and the native composition +root. It owns: + +- the executable entrypoint; +- stdin, stdout, and the inherited fd 3 control lane; +- sidecar wire framing and request routing; +- connection authentication and connection/session ownership; +- extension registration and extension request routing; +- ACP and agent-session orchestration; +- construction of `agentos-driver-tokio`; +- selection and registration of enabled executors; and +- mapping sidecar requests onto the public `agentos-vm` API. + +The sidecar does not implement guest Linux semantics, filesystem semantics, or +engine-specific execution. + +### 3.2 `agentos-vm` + +`agentos-vm` is a library, not a sidecar and not a binary. It owns: + +- the active VM registry; +- VM creation, configuration, lookup, and disposal; +- per-VM generation and lifecycle state; +- composition of the kernel, VFS, storage, and executor contract; +- per-VM resource scopes and limits; +- execution coordination and executor dispatch; +- process start, output, exit, signal, and cleanup coordination; +- mounts, packages, layers, overlays, and snapshots; +- VM SQLite handle resolution; and +- public in-process operations used by the sidecar and tests. + +Its primary public vocabulary should be `VmManager`, `Vm`, `VmHandle`, +`VmConfig`, `VmId`, `VmGeneration`, `VmEvent`, and `VmError`. + +`agentos-vm` does not own: + +- sidecar framing or transports; +- host connection/session authentication; +- ACP, agents, prompts, or durable agent sessions; +- concrete extension selection or implementation; +- construction of a Tokio runtime; +- guest syscall implementations; +- V8, Wasmtime, Pyodide, or Node engine internals; or +- concrete VFS backend implementations. + +### 3.2.1 Direct embedded VM usage + +The Rust architecture must support agentOS as an embeddable virtual OS library +with no sidecar process, client transport, or execution engine. + +There are two supported levels: + +- `agentos-vm-kernel` provides the virtual OS primitives directly: VFS, + processes, descriptors, signals, permissions, mounts, sockets, and related + Linux semantics. It has no Tokio or concrete executor dependency. +- `agentos-vm` with `default-features = false` provides VM lifecycle, + configuration, storage, mounts, snapshots, and kernel composition without + Node/V8, Python/Pyodide, WASM/V8, or Wasmtime. + +The package must be usable directly: + +```toml +[dependencies] +agentos-vm = { + version = "0.0.1", + default-features = false, +} +``` + +```rust +use agentos_vm::{ExecutorRegistry, VmConfig, VmManager}; + +let mut vms = VmManager::builder() + .executors(ExecutorRegistry::empty()) + .build()?; + +let mut vm = vms.create(VmConfig::default().allow_all()).await?; +vm.write_file("/workspace/hello.txt", b"hello").await?; +assert_eq!(vm.read_file("/workspace/hello.txt").await?, b"hello"); +assert!(vm.kernel()?.list_processes().is_empty()); +let snapshot = vm.kernel_mut()?.snapshot_root_filesystem()?; +assert!(!snapshot.entries.is_empty()); +vm.dispose().await?; +``` + +The checked `embedded_os` example must compile against the public API and run +with `agentos-vm`'s default feature set disabled. It must demonstrate direct +file access, process-table inspection, filesystem snapshotting, and explicit VM +disposal through the embedded handle's authoritative kernel accessors. +With an empty executor registry, filesystem, process-table, mount, snapshot, +permission, and other OS operations continue to work. A request that actually +needs a language engine fails with a stable typed +`ERR_AGENTOS_EXECUTOR_UNAVAILABLE` error naming the requested runtime. It must +not panic, silently select an engine, or require a sidecar connection. + +`agentos-vm` therefore defaults to no executors and accepts an injected +executor availability registry. The `agentos-sidecar` default feature set +enables the standard engines, while each individual sidecar feature selects +exactly its corresponding executor crate and VM adapter feature. A +no-default-feature `agentos-vm` build has no concrete executor in its Cargo +dependency graph. + +The no-default-feature build is also the dependency-minimal embedded profile. +It composes `agentos-vm-kernel` with the in-memory VFS and does not compile the +sidecar runtime, Tokio driver, protocol adapter, persistent VFS/SQLite/S3 +backends, package/tar filesystems and schema generation, ARS client, JavaScript +tooling, crypto/TLS services, WASM ABI, or concrete executors. Those +capabilities are explicit Cargo features. +`javascript-tooling` is selected by `node-v8`; `wasm-api` is selected only by +the WASM executor features. The standalone +`agentos-example-embedded-vm` workspace package and the `embedded` Cargo +profile provide the reproducible consumer and size gate. +On the x86-64 Linux validation host, the prior executor-free example was +36,851,256 bytes after stripping. The standalone `embedded` profile build is +772,576 bytes (367,555 bytes gzip), a 97.9% reduction. CI enforces a 1 MiB +ceiling and, separately, rejects any reintroduction of the excluded dependency +families; the size limit alone is not treated as proof of feature isolation. +TypeScript remains native-backed through `@rivet-dev/agentos`; this +requirement does not add an in-process TypeScript virtual OS implementation. + +### 3.3 `agentos-vm-host-interface` + +`agentos-vm-host-interface` is a runtime-neutral, transport-neutral Rust +interface. It owns the request and response types and traits for trusted host +facilities used by the VM: + +- filesystem operations; +- permission decisions; +- persistence and snapshot storage; +- clocks and randomness; +- structured host events; and +- execution-engine context and lifecycle operations. + +It contains no stdio, fd 3, BARE framing, sidecar connection state, Tokio +runtime construction, V8, or Wasmtime implementation. Both local native +implementations and tests may implement the interface directly. + +The primary public traits become: + +| Current | Target | +|---|---| +| `HostBridge` | `VmHost` | +| `BridgeTypes` | `VmHostTypes` | +| `FilesystemBridge` | `HostFilesystem` | +| `PermissionBridge` | `HostPermissions` | +| `PersistenceBridge` | `HostPersistence` | +| `ClockBridge` | `HostClock` | +| `RandomBridge` | `HostRandom` | +| `EventBridge` | `HostEvents` | +| `ExecutionBridge` | `HostExecution` | + +### 3.4 `agentos-resource-accounting` + +`agentos-resource-accounting` remains a runtime-neutral leaf crate. It owns +bounded admission, hierarchical resource ledgers, RAII reservations, queue +tracking, warning thresholds, telemetry observations, and typed limit errors. +It does not own policy defaults or VM lifecycle. + +The name remains unchanged. `resource-limits` would omit its reservation and +telemetry responsibilities, while `vm-resource-accounting` would incorrectly +make a process- and executor-wide facility appear VM-specific. + +### 3.5 `agentos-driver-tokio` + +`agentos-driver-tokio` is the single process-owned trusted work driver. It owns: + +- construction and lifetime of the one Tokio runtime; +- its fixed Tokio worker census; +- bounded trusted task spawning and supervision; +- the fixed bounded blocking executor; +- cancellation and shutdown; +- timers and async wakeups; +- native async I/O facilities used by trusted code; and +- cloneable process and VM-scoped driver handles. + +It does not own: + +- sidecar protocol framing or protocol queue configuration; +- VM identity, VM lifecycle, or executor selection; +- guest process, fd, socket, signal, or filesystem state; +- ACP or extensions; or +- execution of synchronous untrusted guest code on Tokio workers. + +The sidecar constructs the driver once and injects its handle into the VM +manager: + +```rust +let driver = TokioDriver::new(driver_config)?; + +let vms = VmManager::builder() + .driver(driver.handle()) + .executors(executor_registry) + .storage(storage_registry) + .build()?; + +let sidecar = Sidecar::new(vms).with_extension(AcpExtension::new()); +``` + +Each VM receives a generation-bound scoped handle derived from the process +driver. No VM, executor, VFS backend, extension, or sidecar subsystem may +construct another Tokio runtime. + +### 3.6 `agentos-benchmark-baseline` + +`agentos-benchmark-baseline` is an unpublished benchmark binary. It measures +the direct host floor for process, filesystem, DNS, TCP, Unix socket, UDP, +HTTP, pipe, CPU, timer, and allocation operations. Its `wasm32-wasip1` build +measures the supported subset through the VM WASM lane. + +The benchmark harness, not this binary, computes aggregate statistics and the +agentOS emulation tax. No production crate or package may depend on it. + +## 4. Remove the second sidecar vocabulary + +The repository currently exposes both `agentos-native-sidecar` and +`agentos-sidecar` as if they were separate sidecar products. The target has +one process boundary and one sidecar binary. + +Remove: + +- the `agentos-native-sidecar` Cargo package name; +- the `agentos-native-sidecar` executable; +- the `agentos-native-sidecar` protocol schema name; +- `AGENTOS_NATIVE_SIDECAR_BIN`; +- the `@rivet-dev/agentos-runtime-sidecar` binary resolver; +- native-sidecar-specific release artifacts and platform packages; +- native-sidecar-specific benchmark configuration; and +- tests and documentation that describe a second sidecar product. + +Keep: + +- the `agentos-sidecar` executable; +- the `agentos-sidecar` protocol schema name; +- `AGENTOS_SIDECAR_BIN`; +- the `@rivet-dev/agentos-sidecar` binary resolver and platform packages; and +- one set of sidecar build, smoke-test, CI, benchmark, and publish paths. + +Low-level VM clients and high-level ACP clients use the same sidecar binary. +The engine-neutral extension lifecycle/capability adapter permits the sidecar +to expose ACP without introducing ACP or agent dependencies into +`agentos-vm`. The sidecar chooses and constructs the registered extension set; +the VM adapter binds those extensions to authoritative VM resources. + +This repository has no protocol backward-compatibility requirement. Remove the +old names outright; do not add binary aliases, environment-variable fallbacks, +duplicate artifacts, or dual protocol schema names. + +## 5. Replace vague `common` and unqualified `runtime` names + +The V8 support crate is shared specifically by V8-backed executors, so its name +must show that relationship: + +```text +agentos-v8-runtime + -> agentos-executor-v8-runtime +``` + +The WASM shared crate contains the engine-neutral agentOS WASM ABI, generated +imports, validation, profiles, limits, and stable WASM error types. `common` +does not identify that responsibility: + +```text +agentos-executor-wasm-common + -> agentos-executor-wasm-abi +``` + +The generator follows the same namespace: + +```text +agentos-wasm-abi-generator + -> agentos-executor-wasm-abi-generator +``` + +These crates must remain engine-neutral. `executor-wasm-abi` must not depend on +V8 or Wasmtime, and the generator must not become a runtime dependency of +production executors. + +The VM-to-host interface and benchmark floor also receive responsibility-based +names: + +```text +agentos-host-bridge + -> agentos-vm-host-interface + +agentos-native-baseline + -> agentos-benchmark-baseline +``` + +`bridge` is reserved for an actual transport or protocol boundary. `native` +does not describe a benchmark that is also compiled into a WASM comparison +lane. + +## 6. Rust type and module cleanup + +Package renames are incomplete if public types continue to encode the old +architecture. + +Required type changes: + +| Current | Target | +|---|---| +| `NativeSidecar` | split into `Sidecar` and `VmManager` | +| `NativeSidecarConfig` | split into `SidecarConfig` and VM configuration/manager options | +| `NativeSidecarBridge` | remove or replace with a VM-owned bridge bound that does not mention sidecars | +| `SidecarRuntime` | `TokioDriver` | +| `RuntimeContext` | `DriverHandle` | +| VM-scoped `RuntimeContext` | `VmDriverHandle` | +| `RuntimeConfig` | `DriverConfig` | +| `RuntimeBuildError` | `DriverBuildError` | +| `RuntimeMetrics` | `DriverMetrics` | +| `RuntimeMetricsSnapshot` | `DriverMetricsSnapshot` | +| `RuntimeResourceConfig` | `DriverResourceConfig` | +| `HostBridge` | `VmHost` | +| `BridgeTypes` | `VmHostTypes` | +| `FilesystemBridge` | `HostFilesystem` | +| `PermissionBridge` | `HostPermissions` | +| `PersistenceBridge` | `HostPersistence` | +| `ClockBridge` | `HostClock` | +| `RandomBridge` | `HostRandom` | +| `EventBridge` | `HostEvents` | +| `ExecutionBridge` | `HostExecution` | + +The split of `NativeSidecar` is behavioral ownership, not a search-and-replace: + +- connection, protocol, extension, and transport fields move to `Sidecar`; +- VM maps, VM lifecycle, kernel composition, and execution coordination move + to `VmManager`; and +- sidecar request handlers call `VmManager` through its public in-process API. + +Remove `native_sidecar` and `runtime_tokio` from: + +- Rust module paths and test names; +- tracing targets; +- generated protocol schema identifiers; +- environment variables; +- npm binary resolvers; +- CI artifact names; +- benchmark result metadata; and +- architecture documentation. + +Use `agentos_vm`, `agentos_driver_tokio`, and `agentos_sidecar` consistently. + +## 7.

Upstream [released 48.0.3 on September 24, 2026](https://github.com/bytecodealliance/wasmtime/releases/tag/v48.0.3). +Version 48 is an LTS line: under the [release policy](https://docs.wasmtime.dev/stability-release.html), +its [August 20, 2026 release](https://github.com/bytecodealliance/wasmtime/releases/tag/v48.0.0) +receives 24 months of support. Keep taking security +patches within that line; a supported major alone does not make an older patch +safe to ship. + +The September 24 advisories include [Cranelift fuel-accounting amplification](https://github.com/bytecodealliance/wasmtime/security/advisories/GHSA-m63x-6p34-q65x), +which affects earlier 48.x versions and is fixed in 48.0.3. This matters to our +fuel-metered Cranelift execution. The release also fixes component-model fuel +accounting and `wasmtime-wasi`/`wasmtime-wasi-http` issues. Those component and +WASI adapters are not enabled by this executor. This pin addresses the reviewed +upstream advisories as of September 26, 2026; it does not replace review of +agentOS's own host imports or future advisory monitoring. + +Wasmtime has a serious security process: the Bytecode Alliance accepts +[private reports](https://bytecodealliance.org/security), publishes +[GitHub advisories](https://github.com/bytecodealliance/wasmtime/security/advisories), +and documents a [response runbook](https://docs.wasmtime.dev/security-vulnerability-runbook.html) +covering affected versions, CVEs, advance notice, patches, and RustSec entries. +Supported versions receive security backports. Normal versions are supported +for two months and LTS versions for 24 months, according to its +[release policy](https://docs.wasmtime.dev/stability-release.html). Fastly +[runs customer WASM on Wasmtime](https://www.fastly.com/documentation/guides/compute/getting-started-with-compute/), +so this is not an untested runtime. + +The published history also contains failures at the boundary agentOS relies on: + +- In April 2026, a [Cranelift miscompilation](https://github.com/bytecodealliance/wasmtime/security/advisories/GHSA-jhxm-h53p-jm7w) + could let a guest read and write arbitrary host memory on AArch64 when + memory64 was used and relevant mitigations were disabled. The current + Wasmtime 48.0.3 pin is outside the affected versions; this is evidence of + failure mode, not an outstanding vulnerability in that pin. +- A separate [Winch sandbox escape](https://github.com/bytecodealliance/wasmtime/security/advisories/GHSA-xx5w-cvp6-jv83) + affected the optional baseline compiler. This branch enables Cranelift, not + Winch, so that advisory is not directly applicable to its configuration. +- The maintainers [patched 12 advisories, including two critical ones, in + April 2026](https://bytecodealliance.org/articles/wasmtime-security-advisories). + Other advisories cover host denial of service and WASI permission bypasses. + Counts cannot be compared directly with V8's because the products have + different attack surfaces, deployments, and reporting populations. +- The reviewed baseline pinned Wasmtime 46.0.0, while + [GHSA-2hw9-mc66-jc2q](https://github.com/bytecodealliance/wasmtime/security/advisories/GHSA-2hw9-mc66-jc2q) + identifies 46.0.0 as affected and 46.0.2 as patched. The issue requires + particular preemption and Store mutation or reuse patterns; we have not + established an exploit path in agentOS. The integrated tree has replaced + that obsolete, unsupported baseline with 48.0.3; the current pin is outside + this advisory's affected versions. + +V8 has had real vulnerabilities, including +[bugs exploited in the wild](https://chromereleases.googleblog.com/2024/05/stable-channel-update-for-desktop_13.html). +Its advantage for this decision is the much larger, longer-running exposure to +hostile code and the accompanying Chromium security program. V8's own +[security analysis](https://v8.dev/blog/sandbox) says that V8 bugs have featured +heavily in observed Chrome exploits; this is evidence of attacker scrutiny, not +proof that V8 has fewer bugs. Chromium's separate renderer-process protections +do **not** automatically come with an embedded V8 isolate. Embedders also need +to follow the active stable branch: [V8 recommends updating at least every four +weeks](https://v8.dev/docs/release-process). + +Google Cloud's load-balancer plugins are not evidence for Wasmtime adoption: +Google describes a [Google-managed WASM environment](https://docs.cloud.google.com/service-extensions/docs/overview) +without naming its engine. Although Envoy contains a Wasmtime runtime, +[Envoy says it is disabled in its official build](https://www.envoyproxy.io/docs/envoy/latest/api-v3/extensions/wasm/v3/wasm.proto). + +agentOS uses its own POSIX/WASI-style host imports rather than `wasmtime-wasi`. +Thus an advisory confined to `wasmtime-wasi` may not affect this executor, but +the same classes of permission and resource-limit bugs must be reviewed in +our kernel and adapters. Neither runtime's upstream security record validates +agentOS's host-call boundary. The optional Wasmtime backend introduces a second +compiler/runtime security boundary, configuration and advisory stream, and +adapter to maintain while V8 remains necessary for JavaScript. + +## Performance and memory evidence + +The [September 26 integrated-tree benchmark](../../packages/benchmarks/results/wasm-backend-comparison.json) +used source snapshot `d6591c0f41fdd19243b570edc66af1182d7a2a0c`, Wasmtime +48.0.3, and five fresh processes per backend with five samples for each of nine +workloads on one x86-64 host. Correctness passed, and the geometric-mean +workload p50 ratio was `0.236617` (Wasmtime/V8). Warm shell p50 was 48.0 ms +versus 306.8 ms; the host-call-heavy filesystem workload was 39.0 ms versus +172.2 ms. These are whole-workload timings, not isolated host-call binding +latencies. + +Cold-start tails still failed: shell cold p95 was 2,657 ms on Wasmtime versus +327 ms on V8. The throughput/admission gate also failed: Wasmtime admitted +20 of 50 and 20 of 100 requested executions, while V8 admitted all 50 and +100. A faster subset is not an equal-load throughput win. At concurrency 1 +and 10, both backends admitted all requested work and Wasmtime throughput +was 2.5–16.0 times V8's across the repeated/diverse rows. + +Retained-memory gates passed. Median absolute process-tree RSS after VM +disposal was 523,018,240 bytes on Wasmtime versus 526,983,168 on V8; PSS was +520,773,632 versus 524,635,136 bytes. These totals include retained runtime +and compiled-module state, not only live guest memory. The older +[phase-4 artifact](../../packages/benchmarks/results/wasm-backend-comparison-phase4.json) +measured sidecar-only increases over baseline, so its memory numbers are not +directly comparable with these absolute process-tree totals. + +The warm-execution gains support explicit selection, while cold tails and +admission parity still prevent a default change. Eligible copy-on-write +memory initialization is enabled; live Store/Instance snapshots, pooling, +and precompiled native artifacts are not part of this measurement. + +## Gates for changing the default + +Keep the optional backend on a supported, patched Wasmtime release and complete +independent review of guest-memory handling, host imports, limits, cancellation, +and Store lifetime before release. Fix confirmed process and syscall regressions +with reproducing tests. + +Consider making Wasmtime the default only after repeatable benchmarks meet +cold-tail, throughput/admission, and retained-memory targets under representative +module mixes. That decision must account for the ongoing cost of securing two executor +implementations. Until these gates pass, V8 remains the default. diff --git a/docs/design/wasmtime-executor.md b/docs/design/wasmtime-executor.md new file mode 100644 index 0000000000..3a6736a97b --- /dev/null +++ b/docs/design/wasmtime-executor.md @@ -0,0 +1,1339 @@ +# Wasmtime Executor and Shared WASM Host ABI + +Status: implementation and canonical Linux x86-64 validation complete; V8-WASM +remains the default because Wasmtime did not pass the cold-p95 and retained +memory gates + +Audience: agentOS kernel, sidecar runtime, execution, VFS, toolchain, and +registry-software owners + +## 1.

It failed the + individual cold-p95 gate and retained substantially more RSS/PSS after + teardown, so omission continues to select V8. + +agentOS adds Wasmtime as a native executor for standalone WebAssembly +commands. V8 remains the permanent JavaScript executor, including JavaScript +code that uses `WebAssembly.Module`, `WebAssembly.Instance`, or the asynchronous +JavaScript WebAssembly APIs. The existing V8-hosted standalone-WASM runner also +remains available as a compatibility executor. There is no direct bridge +between the two engines: a standalone-WASM process is created under exactly one +selected backend, and both backends reach the same kernel-owned resources +through their adapters. + +Wasmtime becomes the preferred standalone-WASM backend only after conformance, +safety, and performance exit gates close. V8-WASM must remain selectable for +compatibility and diagnosis, must run the shared parity suite, and must not +retain private implementations of Linux semantics. The lockstep client and +protocol surface carries an optional sealed `wasmtime`/`v8` override; omission +uses the sidecar-owned default, so clients do not independently choose or drift +that default. + +The sidecar is the composition root. It depends optionally on the two +standalone-WASM executor crates and is the only crate that selects between +them. This keeps Wasmtime and V8 independently removable from native builds +without moving Linux semantics out of the kernel. + +agentOS continues to use its owned patched `wasm32-wasip1` sysroot and its +existing Preview1 plus `host_*` imports. Wasmtime is the core WebAssembly +engine; it does not become the owner of filesystem, network, process, terminal, +identity, permission, or resource semantics. + +Ahead-of-time compilation, serialized Wasmtime artifacts, components, and live +process snapshots remain outside the implementation. The executor uses ordinary +Wasmtime compilation and a bounded in-process compiled `Module` cache. + +The kernel/executor boundary, signal ownership, shared host-operation services, +and runtime-neutral readiness contract are specified normatively in +[`runtime-neutral-executors.md`](./runtime-neutral-executors.md). This document +owns the Wasmtime engine, linker, guest-memory, limits, feature-profile, +performance, and preferred-backend decisions. Wasmtime-specific code must not +work around an unfinished prerequisite by adding another process-control or +host-service implementation. + +## 2. Outcomes + +The completed migration has these outcomes: + +1. Standalone WASM can execute without a V8 isolate or JavaScript WASI runner + when the Wasmtime backend is selected. +2. JavaScript execution and JavaScript's WebAssembly API remain on V8. +3. V8, Wasmtime, and Python adapters use the same kernel-owned filesystem, + descriptor, process, signal, terminal, identity, permission, and accounting + semantics. +4. External asynchronous I/O remains owned by the process-wide sidecar Tokio + runtime and its bounded capability/readiness machinery. +5. A Wasmtime host import performs ABI decoding and result encoding only. It + does not implement a second filesystem, socket table, process table, or + permission model. +6. Guest execution never runs on a Tokio runtime worker. +7. The plain `wasmtime` selector does not depend on pthreads or shared + WebAssembly memory. The separately gated `wasmtime-threads` selector + supplies those features; neither profile uses AOT artifacts, Wizer, pooling + allocation, or live snapshots. +8. V8-WASM remains a maintained compatibility executor over the same shared + services; neither backend is implemented in terms of the other. +9. Every limit is bounded by default and fails with a typed error naming the + limit and configuration field. + +## 3. Non-goals + +The Phase 2 single-threaded Wasmtime parity milestone did not: + +- replace V8 for JavaScript; +- route JavaScript `WebAssembly.*` calls into Wasmtime; +- create a V8-to-Wasmtime memory or function bridge; +- adopt ambient host filesystem, network, clock, or process access from + `wasmtime-wasi`; +- promise pthread, OpenMP, or general threaded-software compatibility; +- deserialize `.cwasm` or another native-code cache format; +- implement a general live `Store`/`Instance` snapshot or OS-style `fork()`; +- enable every proposal supported by the selected Wasmtime release; +- build a provisional Wasmtime spike before the shared executor/kernel + prerequisite is complete; +- move the process-wide Tokio reactor into `crates/vm-kernel` or create another + Tokio runtime. + +## 4. Baseline architecture before migration + +Before this project, standalone WASM was implemented as a JavaScript execution: + +```text +standalone WASM request + -> sidecar process lifecycle + -> WasmExecutionEngine + -> JavascriptExecutionEngine + -> V8 isolate + -> wasm-runner.mjs + -> WebAssembly.Module / WebAssembly.Instance + -> JavaScript Preview1 and host_* adapters + -> sidecar RPC + -> agentOS kernel, VFS, and native I/O owners +``` + +`WasmExecution` contained a `JavascriptExecution`, and `WasmExecutionEngine` +owned a `JavascriptExecutionEngine`. The JavaScript runner owned four different +kinds of code that had to be distinguished during migration: + +1. **ABI marshalling**: reading pointers, iovecs, strings, arrays, and structures + from guest linear memory and writing results back. +2. **Transport adaptation**: translating imports into sidecar bridge calls and + translating sidecar errors into Preview1 errno values. +3. **Node-WASI compensation**: descriptor shadow maps, synthetic descriptors, + synthetic pipes, preopen collision handling, child polling, and local + `Atomics.wait` loops required by the V8/JavaScript host topology. +4. **Actual semantics**: any behavior that still exists only in the runner and + has not yet moved into the kernel or shared sidecar services. + +The first three categories did not justify a second kernel. Category four was +inventoried operation by operation and either moved to the shared kernel or +retained explicitly as narrow runtime-adapter behavior. + +### 4.1 Current memory evidence + +The current V8 runner has a 2 GiB JavaScript heap ceiling because large WASM +module compilation exceeded the ordinary 128 MiB runner heap. This is a lazy +ceiling rather than immediate resident memory, but guest-driven compilation can +approach it. + +The committed local warm benchmark in +`packages/benchmarks/results/baseline-local.json` reports incremental +sidecar high-water memory above a prewarmed baseline for 19 current WASM lanes: + +- 11.2 MiB minimum; +- 14.6 MiB median across all measured lanes; +- 11.2-20.0 MiB for lanes that do not intentionally move large buffers; +- up to 56.3 MiB for the measured large stream-copy lane. + +These values are useful as the current warm V8-WASM acceptance baseline. They +are not a V8-versus-Wasmtime result: they include sidecar and adapter behavior, +exclude cold compilation through prewarming, and do not separate V8 isolate, +compiled code, linear memory, and kernel buffers. + +## 5. Target architecture + +This design extends the guest-adapter contract in +[`runtime-neutral-executors.md`](./runtime-neutral-executors.md): one sidecar +capability registry, one process-wide Tokio runtime, and no executor-owned +descriptor, poller, resource policy, or permission decision. + +```text +clients / ACP + | +sidecar + | + +-- process lifecycle and runtime selection + +-- process-wide Tokio runtime and native I/O owners + +-- capability, readiness, and cancellation brokers + +-- agentOS kernel + | +-- VFS and mounts + | +-- fd/open-description tables + | +-- pipes and PTYs + | +-- process table and signals + | +-- virtual sockets and DNS policy + | +-- identity, permissions, and resource accounting + | + +-- V8 JavaScript adapter + | +-- JavaScript and JavaScript WebAssembly API + | + +-- Wasmtime standalone-WASM adapter + +-- Engine and bounded Module cache + +-- Store per execution + +-- Preview1 and host_* Linker functions + +-- guest-memory ABI codec +``` + +There is no direct V8-to-Wasmtime bridge. A JavaScript process that spawns a +standalone WASM child uses the existing kernel process API. The sidecar runtime +selector starts the child under the requested standalone-WASM backend, and +stdio, signals, wait status, and exit events use the same cross-runtime process +model as every other child. + +## 6. Code organization + +The implemented organization is: + +```text +crates/executor-wasm-abi/ + abi/ pinned Preview1 WITX source + assets/ generated agentOS ABI manifest + src/abi/ generated registry and stable ABI types + src/profile.rs shared wasmparser proposal profiles + src/execution.rs engine-neutral requests, results, and errors + +crates/executor-wasm-v8/ + src/lib.rs maintained V8-WASM compatibility executor + +crates/executor-wasm-wasmtime/ + src/lib.rs public executor surface + src/engine.rs Config and bounded Engine profiles + src/store.rs per-execution host state + src/module.rs validation and module loading + src/cache.rs bounded in-memory Module cache + src/limits.rs memory, stack, CPU, and cancellation + src/lifecycle.rs start, exit, traps, signals, teardown + src/memory.rs checked guest-memory ABI primitives + src/error.rs stable agentOS outcome normalization + src/linker/ Preview1 plus agentOS POSIX host imports + src/threads.rs separately gated shared-memory/thread support + +crates/vm/src/executor.rs + feature-gated executor composition and dispatch +``` + +The two standalone-WASM engines are separate feature-gated crates. Shared ABI, +profile, and stable-error code lives in `agentos-executor-wasm-abi`; engine-specific +memory, lifecycle, and scheduling code remains in its executor crate. The +sidecar is the only composition and backend-selection owner. + +Runtime-neutral host operations do not belong exclusively under `wasm/`. +Existing kernel and sidecar operations should be exposed through small +capability-oriented services used by both the V8 RPC adapter and Wasmtime +linker. Avoid one enormous `GuestHost` trait and avoid types named +`Javascript*` when Python and Wasmtime use the same operation. + +## 7. WASI and the owned agentOS ABI + +### 7.1 Wasmtime does not force its WASI implementation + +The `wasmtime` engine and `wasmtime-wasi` are separate crates. A core Wasm +module imports functions by module and function name, and a Wasmtime `Linker` +supplies whichever definitions the embedder chooses. agentOS can therefore +provide its existing `wasi_snapshot_preview1`, `host_process`, `host_net`, +`host_user`, `host_fs`, and `host_tty` modules without installing ambient +`wasmtime-wasi` host resources. + +There is no conflict between using Wasmtime as the engine and using the +agentOS-owned WASI/POSIX ABI. The danger is only in accidentally linking a +second ambient implementation that opens host files or sockets outside the +agentOS kernel. + +### 7.2 Integration decision + +The implementation: + +- treat the patched sysroot and `toolchain/crates/wasi-ext` imports as the + guest ABI source of truth; +- link exactly the Preview1 and custom-import surface generated in + `crates/executor-wasm-abi/assets/agentos-wasm-abi.json` and required by built + software; +- route every resource-bearing operation to an agentOS kernel or sidecar + service; +- avoid constructing a default ambient `WasiCtx` with host preopens, host + sockets, or inherited host stdio; +- generate Preview1 signatures and value layouts from the pinned checked-in + WITX description, but do not adopt upstream resource ownership or policy; +- generate custom-import signatures and repetitive bindings from the one + checked-in agentOS ABI manifest instead of manually duplicating signatures in + Rust and JavaScript. + +If an upstream helper cannot be backed by agentOS descriptors without creating +parallel state or ambient authority, the Wasmtime linker will implement that +thin ABI function directly. + +## 8. Dependency on shared host services + +The required refactor lives in +[`runtime-neutral-executors.md`](./runtime-neutral-executors.md). The completed +function-level inventory, baseline, and locked Phase 0 decisions live in +[`wasmtime-phase-0.md`](./wasmtime-phase-0.md). Wasmtime is admitted only after +the runtime-neutral document's exit gates close for the entire currently +supported V8-WASM ABI and working-software surface. + +The Wasmtime adapter receives: + +- a generation-bound execution control cell registered with the kernel process; +- a kernel PID and exit-reporter capability; +- capability-sized filesystem, network, process, terminal, signal, identity, + clock, and entropy host services; +- a runtime-neutral coalesced wake handle and direct operation waiters; and +- typed limits, permissions, cancellation, and error mapping. + +The linker does not know about `ActiveProcess`, `V8SessionHandle`, Node-WASI +fd aliases, sidecar signal maps, native Tokio handles, or mutable `KernelVm` +ownership. It decodes the owned agentOS ABI into bounded values and calls the +shared services. + +Engine-specific responsibilities remaining in this document are safe linear +memory access, async suspension, Wasmtime interruption, module validation and +caching, feature configuration, trap normalization, and execution teardown. +## 9. Async guest-memory contract + +Wasmtime async host imports cannot retain a borrowed guest-memory slice or a +`Caller`-derived view across an `.await`. This is not an architectural blocker; +it defines the adapter boundary. + +Every async import uses three phases: + +1. **Decode and prevalidate:** validate all pointers, lengths, iovec counts, and + output ranges; enforce byte/count limits; copy input strings, structures, + address data, and write payloads into bounded owned Rust values. +2. **Await shared operation:** call the kernel/sidecar service using owned values + and opaque process/capability identity. Retain no raw guest pointer, slice, + or store borrow. +3. **Reacquire and encode:** reacquire the Wasmtime memory through the Store, + validate output ranges again, and copy the bounded result back. + +Examples: + +- `fd_write` snapshots iovec metadata and payload bytes before awaiting the + kernel write. +- `fd_read` snapshots destination iovecs, awaits an owned result buffer, then + reacquires memory and scatters the bytes. +- `net_connect` copies the address before awaiting readiness. +- `recv`, `accept`, and DNS calls await owned results and only then write guest + memory. +- `proc_spawn` copies command, argv, env, and actions and prevalidates the pid + result pointer before performing the side effect. +- `waitpid` prevalidates status outputs before reaping a child. + +For the initial single-threaded executor, the suspended Store cannot execute +guest code concurrently and linear memory cannot shrink. Reacquisition is still +required because memory growth can relocate backing storage. With future shared +memory, another guest thread may mutate memory while an import is suspended; +input structures and destination addresses therefore remain snapshotted once +rather than reread after the await. + +This introduces an owned-buffer copy for asynchronous I/O. The current V8 path +already performs JavaScript and bridge copies, so the Wasmtime path may still +reduce total copying, but the benchmark must measure this rather than assume it. + +Signal handlers follow the same memory rule and the existing cooperative +agentOS ABI. A caught signal may run at an import, `sched_yield`, top-level +call boundary, or another declared safe point; neither V8-WASM nor Wasmtime can +inject `__wasi_signal_trampoline(i32)` into arbitrary pure guest computation +and then resume that computation. Epochs provide bounded STOP scheduling and +terminal interruption, not caught-handler injection. The adapter must: + +- claim exactly one kernel delivery token, invoke the trampoline, and close or + explicitly disarm that token before claiming the next signal; it must never + preclaim a FIFO batch against the kernel's LIFO delivery scopes; +- validate the trampoline's exact type before accepting a user disposition and + initialize the inherited mask through `__agentos_set_initial_sigmask` before + `_start` and after successful exec replacement; +- keep a restartable operation's same durable waiter alive across a handler, + so retry cannot duplicate an accept, read, write, lock, or other side effect; +- let an atomically committed or partial operation result win a simultaneous + signal race; otherwise return `EINTR` unless every delivered handler carried + `SA_RESTART`; and +- reacquire and revalidate memory after the handler, because the handler may + grow or mutate linear memory. Handler trap, exit, exec, nested delivery, and + terminal interruption each have an explicit token-cleanup path. + +The shared host-operation API owns the authoritative restartability enum and +completion-versus-signal arbitration. Engine adapters do not scatter their own +restart booleans or cancel and reissue side-effecting operations. + +## 10. Runtime placement and scheduling + +The normative async/blocking ownership and waiter sequence are defined in +[`runtime-neutral-executors.md`](./runtime-neutral-executors.md#71-async-and-blocking-execution-contract). +Wasmtime does not introduce a scheduler exception to that contract. + +Wasmtime does not provide an execution thread pool. Guest execution occurs +synchronously while a Wasmtime future is polled. Therefore: + +- Wasmtime execution futures run on the bounded non-Tokio VM executor; +- async host operations use the one process-wide sidecar Tokio runtime; +- no Tokio worker synchronously enters Wasmtime guest code; +- no executor or VM creates another Tokio runtime; +- epoch/fuel yields bound uninterrupted guest work and provide cancellation + points; +- blocking host work uses the existing fixed, bounded blocking executor with + admission. + +The Wasmtime Store carries VM id, generation, process id, permission profile, +limit ledger, cancellation state, readiness sink, and access to the shared +host-operation services. Guest-controlled payloads do not supply authority. + +## 11. Safety and limits + +The initial executor must preserve or improve the existing controls: + +| Control | Initial Wasmtime behavior | +| --- | --- | +| Module bytes and parser work | Preserve the 256 MiB file cap and bounded import/memory/varuint parsing before compilation. | +| Linear memory | Preserve the 128 MiB default, validate declarations, enforce growth through Store limits, and account aggregate guest memory outside per-memory limits. | +| Stack | Use Wasmtime's stack cap through a bounded set of Engine profiles because stack configuration is Engine-wide while agentOS configuration is per VM. | +| CPU and cancellation | Use epoch checks as the unbypassable interruption mechanism, but preserve the current active-CPU rather than wall-time policy: executor accounting tracks only guest-running intervals and refreshes the Store deadline after async waits. Use fuel only for an explicitly deterministic budget. | +| Wall time | Remain opt-in for interactive commands; use an outer cancellable deadline when configured. | +| Files, fds, pipes, PTYs, sockets, processes | Continue to enforce in the kernel and shared sidecar ledgers. | +| Output and queues | Preserve current bounded output, reactor, bridge, readiness, and completion limits. | +| Permissions | Omit prohibited imports at link time and repeat authorization at the kernel operation. | +| Errors | Return stable agentOS/POSIX typed errors; do not expose engine error strings as API contracts. | + +The current `maxWasmFuel` field means milliseconds in the V8 runner, not fuel. +It must not silently change meaning. Phase 1 removes it lockstep and adds +`activeCpuTimeLimitMs`, optional `wallClockLimitMs`, and optional +`deterministicFuel` as three distinct fields. +The default runaway-guest safeguard is currently 30 seconds of active V8 CPU, +while an explicitly configured `maxWasmFuel` is an opt-in wall-clock timeout. +Wasmtime must preserve that distinction: time spent blocked on terminal, +network, filesystem, child, or timer waits cannot exhaust the default active +execution budget. + +Wasmtime charges the direct execution thread, or the entire isolated threaded +worker process, against one active CPU allowance across Stores. Image replacement +carries the remaining allowance; worker teardown charges observed process CPU +plus a conservative bound for the final reap interval. Blocked wall time does +not consume CPU, but worker runtime work does. Clock failures fail closed. +Deterministic fuel survives image replacement. Because Wasmtime fuel is local +to each Store, a module importing `wasi.thread-spawn` with `maxThreads > 1` +rejects explicit `deterministicFuel` with +`ERR_AGENTOS_WASM_THREADS_DETERMINISTIC_FUEL_UNSUPPORTED`; use the active CPU +limit or `maxThreads: 1`. Shared memory alone does not trigger this rejection. + +## 12. Shared memory and threads + +Three mechanisms must remain distinct: + +1. The current runner creates small local `SharedArrayBuffer` objects so + `Atomics.wait` can block its own V8 execution thread without busy-spinning. +2. Legacy synchronous bridges can use shared buffers to coordinate a + JavaScript worker with a host thread. +3. WebAssembly threads use shared linear memory and atomic WASM instructions + across multiple executing agents. + +The native standalone runner does not rely on shared memory between V8 isolates +for filesystem, networking, process, or kernel state. Guest `worker_threads` +is an inert compatibility surface, not a source of real V8 worker isolates. +Removing the V8-hosted standalone runner therefore does not require sharing +memory between V8 and Wasmtime. + +Wasmtime shared memory is a later milestone. Runtime support alone is +insufficient because the current agentOS sysroot links emulated single-thread +pthreads. Real pthread support requires a threaded sysroot, a bounded +thread-spawn ABI, real mutex/condvar/TLS behavior, group cancellation, and +per-VM plus process-wide thread admission. + +Wasmtime 46 does not expose a supported host hook that can replace or cancel a +guest blocked in `memory.atomic.wait`. Epoch interruption, fuel, dropping an +async call future, and dropping ordinary Store handles do not provide a hard +reap guarantee for that parked native thread. The threaded profile must +therefore run each WASM thread group in a killable worker process unless a +reviewed later Wasmtime API supplies an equivalent bounded interruption +primitive. The parent sidecar remains the sole kernel and policy authority; +the worker receives typed host operations over a bounded control lane, never +ambient filesystem or network resources. Teardown must first request an orderly +group stop, then terminate and reap the worker at a fixed deadline. + +The first executor rejects modules that define or import shared memories and +does not expose a thread-spawn import, regardless of Wasmtime's compile-time +threads feature default. It must not use the experimental upstream +WASI-threads integration that can terminate the entire host process when one +guest thread traps. + +## 13. Compilation cache and snapshots + +The first implementation does not persist native compiled artifacts and does +not deserialize AOT files. The unsafe-artifact concern is therefore deferred, +not an initial blocker. + +The allowed initial cache is a bounded, process-memory cache of trusted +`Module` values keyed by module contents and Engine profile. It improves +repeat execution within one sidecar process but does not survive restart. +Wasmtime `Module` compilation is synchronous and complete at construction; +there is no later optimizing tier. `Module` clones are shallow and the compiled +code is shareable across threads, so this cache avoids recompilation without +copying the native code image. The implementation should also benchmark caching +`InstancePre` values, which can reuse import resolution and type checking when +all closed-over imports are Store-independent. + +Snapshot support is classified as follows: + +- **V8 JavaScript heap snapshot:** remains available to the JavaScript + executor; it is unrelated to a running standalone WASM process. +- **In-memory compiled Module reuse:** in scope for the first Wasmtime + executor. +- **Wasmtime serialized/AOT module:** explicitly deferred. +- **Copy-on-write module memory initialization:** may be benchmarked after the + basic executor works. Wasmtime's `memory_init_cow` is enabled by default and + can use Linux memory mappings or `memfd_create` for eligible modules whose + initial data has static, in-bounds offsets. This speeds memory initialization; + it is not a live guest snapshot and does not require serialized AOT input. +- **Wizer build-time preinitialization:** deferred and opt-in if later useful to + individual software packages. +- **Live Store/Instance snapshot or fork:** unsupported in the first design. + +Open files, sockets, processes, timers, permissions, host capabilities, and +threads are sidecar/kernel state and cannot be captured by merely copying WASM +linear memory and globals. + +## 14. Performance and memory validation + +No external benchmark is accepted as the agentOS answer because host imports, +module sizes, V8 topology, kernel bridges, and cache configuration dominate the +comparison. The repository must measure both backends under the same sidecar, +kernel, command modules, release build, and hardware. + +There is no defensible numeric V8-versus-Wasmtime result yet. The existing +11.2-20.0 MiB ordinary warm-command range is the V8-WASM baseline, not an +engine comparison. The initial Wasmtime implementation and direct benchmark +are required before claiming a cold-start or resident-memory win. + +The benchmark records these phases independently: + +```text +sidecar and VM baseline +runtime/package projection +Engine lookup or creation +module read and validation +module compilation or in-memory cache lookup +Linker/import resolution +Store and async-stack allocation +instantiation and memory initialization +_start to first host call +first stdout byte +completion and teardown +``` + +The matrix includes: + +- current V8-WASM cold compile and warm compile-cache paths; +- Wasmtime cold compile and warm in-memory Module-cache paths; +- trivial, coreutils, shell, curl, sqlite, vim, and large-module commands; +- compute-heavy and host-call-heavy workloads; +- concurrency 1, 10, 50, 100, and 200; +- repeated-module and diverse-module workloads; +- success, denied permission, cancellation, and resource-limit paths. + +Memory measurements include process baseline, incremental RSS/PSS, peak RSS, +virtual-address reservation, committed linear-memory bytes, compiled-code +cache bytes, async stack bytes, kernel buffer bytes, page faults, and memory +retained after teardown. Large virtual reservations must not be reported as +resident memory. + +On a 64-bit host, current Wasmtime defaults reserve 4 GiB of virtual address +space plus guard regions for each 32-bit linear memory so generated code can +elide many explicit bounds checks. Reservation is not committed RSS. agentOS's +128 MiB accessible-memory policy still requires a Store resource limiter and +aggregate accounting; it does not by itself reduce Wasmtime's virtual +reservation. The initial implementation must benchmark default reservation +against a smaller reservation because reducing it can add bounds checks or +memory-growth relocation. + +Wasmtime async execution also allocates a separate native stack used for stack +switching when an async host function suspends. Measure this per active Store at +the target concurrency. Configure `async_stack_size` as the selected WASM stack +cap plus 1.5 MiB of host-call headroom (2 MiB for the default 512 KiB profile), +charge the whole reservation before Store admission, and reject overflow rather +than assuming the engine default is negligible. + +The pooling allocator is deferred. It can improve reuse and high-concurrency +instantiation, but requires fixed process-wide slot counts, can reserve roughly +one multi-gigabyte virtual-memory slot per admitted linear memory, and may +retain resident pages in warm slots. Start with on-demand allocation, establish +the workload and memory baseline, then evaluate pooling as an independent +optimization. + +The hypotheses to test are: + +- Wasmtime removes the per-execution V8 isolate and JavaScript runner heap; +- process-global V8 memory remains because JavaScript still uses V8; +- compiled Wasmtime Modules can be shared across executions in one process; +- Wasmtime may reserve more virtual address space for linear memories while + consuming less resident adapter memory; +- direct typed host calls reduce JavaScript/bridge overhead, but owned buffers + required across async waits still impose copying; +- threaded execution, when added, materially increases memory through one + Store/instance/native stack per admitted thread. + +Cutover requires no regression against the current warm V8-WASM memory and +latency baselines for representative commands, or an explicitly approved +tradeoff supported by measurements. + +## 15. Behavioral parity and errors + +agentOS does not promise V8 error strings, Wasmtime error strings, or identical +compiler diagnostics. It does promise stable sidecar error categories and +Linux-compatible guest-visible behavior. + +The adapter normalizes: + +- malformed/unsupported module; +- missing or incompatible import; +- memory, table, and stack limit; +- CPU/fuel exhaustion; +- explicit termination; +- guest trap; +- host-operation errno; +- process exit and terminating signal; +- internal executor fault. + +Differential tests assert stdout, stderr, exit status, errno, signal behavior, +fd inheritance, permissions, and side effects. Floating-point and proposal +behavior follow the selected published agentOS WASM feature profile rather than +whichever features an engine happens to enable by default. + +## 16. Delivery phases and JJ revision contract + +Each phase below lands as one distinct JJ revision, in order. A phase may be +developed through temporary local revisions, but those revisions are folded +before handoff so the review and landing stack has one revision per phase. Do +not mix Wasmtime implementation into the prerequisite refactor revision. Do +not collapse the prerequisite refactor and Wasmtime executor into one revision. + +This intentionally produces a small semantic stack instead of one revision per +capability family: + +1. specification and frozen baseline; +2. complete runtime-neutral kernel/executor refactor; +3. complete initial Wasmtime executor at current V8-WASM feature parity; and +4. performance validation and preferred-backend decision; +5. separately gated threaded-WASM support; and +6. final dual-backend, toolchain, release-artifact, soak, and workspace + validation, including correctness fixes exposed by those gates. + +The initial Wasmtime project is complete at the end of Phase 3: Wasmtime passes +the entire current V8-WASM ABI and working-software corpus, is production-ready, +and can be the preferred backend while V8-WASM remains a supported selection. +Phase 4 expands that completed executor with threads. Phase 5 is the +merge-readiness proof for the complete stack and does not introduce another +runtime architecture. + +This section is the canonical implementation tracker. Check an item only in +the JJ revision that supplies its implementation and evidence.

Completion of this checkbox means the initial production Wasmtime + project is complete. + +Phase 3 evidence (Rust 1.94.0, release profile, Linux x86-64 canonical +workspace, 2026-07-20 Pacific): + +- The canonical matrix used the same release sidecar, host-service route, + permissions, limits, output capture, and SHA-256-inventoried source modules + for both engines. V8's existing safety transform adds a maximum to an + uncapped memory section (two bytes for this corpus); diagnostics record both + the identical source size and the transformed executable size. +- Five fresh sidecar processes per engine ran five samples for each of nine + distinct workload modules, including a real recursive `find` host-call case. + Per-execution diagnostics record setup, Engine, read, profile validation, + compile/cache, Linker, Store/async stack, Instance (including memory + initialization), first host call, first guest host call, first output, + completion, teardown, guest linear memory, and Store reservations. +- Repeated and diverse 1/10/50/100/200 concurrency rows completed. The 20-way + executor bound and 128-frame ingress bound produced their documented typed + admission failures above capacity; every comparable successful Wasmtime row + exceeded V8 throughput. Permission denial, abort cancellation, and active-CPU + limit paths passed for both engines. +- Correctness, geometric-mean p50 (`0.2972` Wasmtime/V8), and throughput gates + passed.

The child owns only Wasmtime Engine/Store/Instance/shared-memory and + guest-thread state; the parent retains the kernel, VFS, descriptors, sockets, + permissions, processes, and signal dispositions.

It must validate request metadata and remove + both fixed and `Connection`-nominated hop-by-hop fields before socket + admission. +- [x] Rebase the complete six-revision stack onto the current mainline without + collapsing phase boundaries; reconcile the grouped client/process APIs, + `/__agentos` command projection, generated protocol, bridge behavior, and + dual-backend CI rather than retaining stale compatibility surfaces. +- [x] Route buffered and streamed kernel-owned `vm.fetch` progress through the + bounded VM-scoped process-event pump. The HTTP adapter performs only + nonblocking socket probes; deferred host-call completions and readiness + wakeups remain internal, fair executor events and never wait in the + public process-event queue. +- [x] Seal validation and its correctness fixes as one independently reviewable + revision above the threaded executor revision. + +Phase 5 evidence (Rust 1.94.0, Linux x86-64 canonical workspace, +2026-07-23 Pacific): + +- `just tools-rebuild` completed from source and staged **169 commands from 138 + distinct modules**. A second pinned Codex build from the reused checkout also + completed after its target-specific state was deliberately cleaned. The audit + observed **146 unique module/function imports**; every import matches the + generated 169-function/29-signature agentOS ABI. +- The clean bounded PR build compiled 101 binaries, assembled 119 Rust/alias + entries, added the C-backed `mknod`, `mkfifo`, and `getconf` commands, and + passed required coreutils staging with 122 commands. An architecture guard + pins the C-backed command list and its derived build/install contract. The + pinned LLVM source archive uses the direct codeload endpoint, bounded + retries, and an exact SHA-256 check. The pinned Binaryen installer likewise + uses GitHub's release-asset API with platform-specific immutable asset IDs, + bounded retries, a browser-download fallback, and the existing per-platform + SHA-256 checks. +- The exact serialized Rust workspace run passed end to end. Representative + aggregate results were execution 244/244, Python 38/38, sidecar service + 389 passed with 2 explicit ignores, raw ABI 9/9, Wasmtime safety 20 runnable + tests with the generated pthread fixture reserved for its explicit gate, and + xfstests 42 passed with 27 documented host-kernel, endurance, or + storage-policy exclusions. All VFS, client, protocol, and doc tests also + passed. +- The complete native core suite ran under each standalone-WASM backend: + V8 and Wasmtime each passed 516 tests with 41 deliberate skips across 100 test + files. The PTY default suite passed 20/20 and its C matrix passed 40/40 under + each backend. The release/nightly registry matrix passed 94/94 under each + backend, and actor, ACP, OpenCode, Pi, Codex, shell, Vim, curl, process, + filesystem, and network flows passed. +- The complete actor lifecycle and conformance suites passed 12/12 under both + `v8` and `wasmtime` after the shared kernel-owned HTTP projection was tested + with deliberately conflicting source `Content-Length` and + `Transfer-Encoding` headers. The serializer strips framing/hop-by-hop + headers (including `Connection`-nominated fields), validates method/header + metadata before socket admission, computes framing from the actual decoded + body, and settles a response completed during the current readiness probe. +- The post-rebase core rerun exposed three compatibility defects rather than + weakened assertions: the V8 bridge installed the standard `WebSocket` global + with a non-Node property descriptor, the custom JavaScript mount fixture did + not grant its unprivileged guest write access, and module resolution rebuilt + its filesystem cache for every bridge RPC. The bridge now matches Node's + writable/configurable/non-enumerable descriptor, the fixture sets explicit + Linux permissions, and the per-process module cache is keyed to the kernel + VFS mutation generation. The affected Pi/ACP flows passed 5/5; the complete + core rerun passed 247 tests with 14 deliberate skips, and its two stale local + fixture-cache misses passed from a fresh fixture cache. +- The final mainline reconciliation added focused streamed-fetch regressions + for deferred managed networking before response headers and during body + reads, two simultaneous kernel-assigned client ports, exact one-slash request + targets, and binary body preservation. Those cases pass, along with the + buffered, streaming, and one-shot-exit loopback tests. The sidecar + library passes 280 tests with one intentional performance ignore; the rerun + also corrected stale `/__secure_exec` command-path expectations to the live + `/__agentos` projection and restored typed-error tests after removal of + message-to-errno parsing. +- The final Node ecosystem parity run passed **87 fixtures with 6 explicit + environment/upstream/deferred skips and 0 failures**. Astro and Vite React + now pass. The only intentionally recorded Node test-runner gap remains + automatic `node:test` execution/reporting; module import, registration, and + manual shim execution work. Exhaustive reruns also fixed three V8 + compatibility boundaries: raw bridge reads reserve for base64/JSON expansion + instead of only decoded bytes; `StringDecoder` accepts typed-array and + `ArrayBuffer` views produced by current Execa; and JavaScript launch mode uses + the resolved guest package scope while preserving unscoped inline-source + compatibility. A trusted Python `.mjs` runner now overrides stale CommonJS + launch state inherited from a JavaScript parent. A subsequent nightly run + under runner uid/gid 1001/1002 exposed that process-scoped file writes could + leak the lower VFS's host-only auto-parent behavior: `/.next` had the correct + guest owner, while implicitly created descendants reverted to 1000/1000. + Process-scoped file creation now requires its immediate parent to exist, + matching Linux. The kernel regression, non-default-identity fork regression, + exact uid-1001 container reproduction, and complete 87-fixture catalog all + pass. +- The final correction head also passes the browser-excluded native workspace + check, warning-denied all-targets Clippy, the filtered 61-task JavaScript + build, all 137 package typecheck-contract checks, and the complete normal + 227-task repository test lane. That lane explicitly executes shell children + through `v8`, `wasmtime`, and `wasmtime-threads`; all three selectors pass. +- Fresh production release sidecars passed the packed-artifact smoke under + `v8`, `wasmtime`, and `wasmtime-threads`. The packed runtime contained all 169 + commands. After rebasing onto current `main`, root `pnpm build` passed 63/63 + tasks, `pnpm check-types` passed 121/121 tasks, and the website generated 153 + pages. The repository-wide + nonblocking Biome lane was also run and reproduced its inherited baseline + (599 errors and 361 warnings across examples, generated sources, and + unrelated packages); required CI already marks that lane `continue-on-error`, + and the Wasmtime stack adds no new required lint gate. +- Explicit expensive gates passed: the generated pthread/libc fixture, hostile + threaded isolation/termination tests, multigeneration/protocol soaks, and a + 200-cycle mixed V8/Wasmtime run with zero residual process or thread growth. + The mixed result is in + `packages/benchmarks/results/wasm-mixed-soak.json`. +- The threaded benchmark completed 8 groups/24 guest threads. Its cold p50 was + 39.07 ms, cold p95 was 46.77 ms, warm throughput was 18.60 executions/s, + one-group PSS was 17.68 MiB, maximum eight-worker PSS was 18.90 MiB, + incremental guest-thread memory was 173,787 bytes/thread, and fixed-deadline + termination was 44.16 ms. Raw results are in + `packages/benchmarks/results/wasmtime-threads.json`. +- The exact-head PR benchmark reproduced an inherited tiny-row gate + discontinuity: `fs_read_small` failed at 1.07 ms and 1.25 ms, while + pre-change heads had failed at 1.22 ms/1.29 ms and passed at 0.88 ms. Tiny + baselines below 0.5 ms now ignore less than 1 ms of absolute regression + instead of switching policy at a 1 ms current value. They still fail when + both the normal ratio and 1 ms absolute-regression thresholds are exceeded; + normal rows remain ratio-only. Direct unit coverage is part of the cheap CI + lane. +- The first exact-head nightly run found a CPU-count-dependent false failure in + the inherited 128-child late-stream test. On its four-executor runner the + guest received the documented, typed `EAGAIN` admission response naming + `runtime.executor.maxActiveVms`; the same test passed on a larger runner. + The regression still starts and verifies all 128 children and retains four + concurrent workers, but now retries only that exact bounded-admission + response. Unrelated spawn errors, stream loss, stderr, exit status, ordering, + and output mismatches still fail. A four-CPU focused reproduction passed all + 128 result checks. +- The first exact-head Wasmtime/memory xfstests report contained 42 passes, no + filesystem failures, and no harness failures before strict reporting stopped + at `generic/082`: upstream reported `Quota user tools not installed`, but + that test lacked the exact reviewed exception already used by the other + quota-only cases. The concurrent V8/chunked-S3 report independently stopped + on the same missing classification with no filesystem or harness failures, + confirming that this was manifest policy rather than an engine difference. + `generic/082` now has per-storage-backend + `allowed-notrun` records matching that literal reason. The runner remains + fail-closed for any different test, backend, result, or reason; quota tooling + and enforcement remain outside the maintained V8-WASM parity baseline. +- The next exact-head V8/memory, V8/chunked-local, Wasmtime/memory, and + V8/chunked-S3 reports each reached 53 passes with no filesystem failures + before the same strict manifest check rejected `generic/110` and + `generic/111`. The pinned upstream helper checks for an `xfs_io reflink` + command before it checks the filesystem type, so the maintained command + surface deterministically reports `xfs_io reflink support is missing`. + Static helper-order review plus a real V8/memory command audit followed all + 451 reviewed `allowed-notrun` IDs. It retained that exact reflink capability + reason for 140 test IDs and 560 backend records, while correctly preserving + earlier gates for three swapfile IDs and adding exact earlier capability + reasons for one extsize ID, 21 fscrypt IDs, and one statx ID. Unrelated + dedupe and explicitly patched logical-feature gates retain their own reasons. + The final uninterrupted audit passed 451/451 with zero unclassified, + mismatched, filesystem-failure, or harness rows in 1,875.25 seconds; the + 1,920-record manifest and its 12 schema/runner unit tests also passed. +- Single-thread comparison still fails the cold-p95 and retained RSS/PSS + thresholds, so V8 remains the sidecar-owned default. Wasmtime and + Wasmtime-threads remain explicit production selectors; AOT, serialized + artifacts, pooling, Wizer, and live snapshots remain disabled. +- `cargo audit` reported zero known vulnerabilities and five upstream + maintenance/yank warnings. `pnpm audit --prod --audit-level high` reported 92 + inherited repository-wide advisories (2 critical, 31 high, 47 moderate, 12 + low); none was introduced by the Wasmtime dependency path, but the existing + production dependency baseline remains a repository-level release concern. + +## 17.

Purpose and completion statement + +This document closes Phase 0 of the Wasmtime executor project. It records: + +- every import exposed by the current standalone V8-WASM runner; +- the semantic owner, authority, bounds, waiting behavior, guest-memory + direction, shared operation, and parity proof for each import; +- compatibility aliases, hard stubs, and unsupported imports; +- the current V8-WASM cold/warm latency and memory baseline; and +- the implementation decisions that must not be reopened implicitly during the + runtime-neutral refactor. + +The inventory was checked against: + +- `crates/executor-wasm-abi/assets/agentos-wasm-abi.json`; +- `crates/executor-v8-runtime/assets/runners/wasm-runner.mjs`; +- `crates/executor-v8-runtime/assets/runners/wasi-module.js`; +- `toolchain/crates/wasi-ext/src/lib.rs`; +- `toolchain/std-patches/` and `toolchain/std-patches/wasi-libc-overrides/`; +- kernel process, VFS, fd, socket, PTY, identity, and resource-accounting APIs; + and +- sidecar execution, filesystem, and network services. + +No import below permits Wasmtime to use ambient host resources. `wasmtime-wasi` +does not own the context. Both engines call the same agentOS host services. + +## 2. Inventory notation and cross-cutting contract + +The tables use these abbreviations: + +- **C**: canonical current ABI; implement for both engines. +- **A**: active compatibility alias/version; keep the linker function but map it + to the canonical operation. +- **S**: current hard stub; Phase 1 either implements it in the shared owner or + removes it only after a rebuilt-artifact import audit proves it unused. +- **U**: intentionally unsupported; validation/linking fails deterministically. +- **all/full/limited**: permission tier availability. Authority is checked again + in the shared operation even when an import is omitted at link time. +- **sync**: bounded non-waiting semantic operation. +- **async**: readiness, timer, network, lock, FIFO, PTY, child, or cancellation + wait. The V8 adapter may expose it through its existing synchronous bridge; + the shared operation itself is asynchronous. +- **in/out**: bytes copied from/to guest memory. All ranges and aggregate sizes + are validated before a side effect. No guest-memory borrow crosses an await. + +Common default limits are `maxOpenFds=1024`, `maxPipes=128`, `maxPtys=128`, +`maxSockets=256`, `maxConnections=256`, `maxSocketBufferedBytes=4 MiB`, +`maxSocketDatagramQueueLen=1024`, `maxPreadBytes=64 MiB`, +`maxFdWriteBytes=64 MiB`, `maxProcessArgvBytes=1 MiB`, +`maxProcessEnvBytes=1 MiB`, `maxReaddirEntries=4096`, a 4096-byte path, 40 +symlink traversals, 64 supplementary groups, 255-byte xattr names, and 64 KiB +xattr values. Every adapter additionally caps one decoded iovec, pollfd, or +poll-subscription array at the Linux-aligned 1024 entries and its encoded +descriptor bytes at 1 MiB before copying. Spawn file actions have their own +4096-entry and 1 MiB encoded-byte caps; SCM_RIGHTS carries at most 253 +descriptors. These adapter caps become named configurable limits if real +software reaches them; they never silently become unbounded. + +Multi-output imports prevalidate every output range before committing a side +effect. Operations that allocate guest fds reserve fd capacity before the host +operation and roll back completely if result encoding fails. Errors remain +typed errno/status values across the shared boundary. + +## 3.

The bounded byte, string, vector, + and count constructors are required to receive that named limit and reject + before operation construction (`bounded_values_reject_before_admission` and + `common_payload_constructors_require_named_limits`). +- [x] **Runtime-neutral retained resources.** `ResourceLedger` proves exact + child-scope admission, 80% warning/rearm, limit-plus-one typed fields, parent + rollback, and release-to-zero in + `named_limit_proves_boundary_warning_typed_rejection_and_rollback` and + `failed_child_admission_rolls_back_parent`.

It staged 169 command entries +from 138 distinct modules. The generated ABI remained current at 169 +functions. + +Those 169 manifest rows have 29 distinct core function signatures. The 40 +Preview1 rows also link through the `wasi_unstable` module alias, yielding 209 +effective linker names without duplicating implementations. The inventory +tables contain 111 semantic rows: 110 supported binding groups plus the one +intentional unsupported-import group. The generated registry must preserve +those counts and map every import to explicit handler, decoder, encoder, +execution-class, restartability, return-convention, permission, and +transaction/prevalidation metadata. + +The automated Binaryen audit inspected all 169 staged command entries and +found 146 unique module/function imports. Every observed import has the exact +signature declared in Sections 3–7; no undeclared import or conflicting +signature remains. The artifact set specifically confirms that both +`path_chown`/`fd_chown` legacy aliases and `proc_spawn_v3`/`proc_spawn_v4` plus +`proc_waitpid_v2`/`proc_waitpid_v3` version pairs remain live. Generated command +and package outputs are ignored build evidence and are not committed. + +## 10. V8-WASM performance and memory baseline + +Two current measurements serve different purposes. + +The committed warm resource matrix at +`packages/benchmarks/results/baseline-local.json` was captured on a +12th-generation Intel i7-12700KF, 20 logical cores, 62.6 GiB RAM, Node 24.17.0, +Linux 6.1 x86-64, with 20 iterations after five warmups. Across ordinary +V8-WASM lanes the incremental sidecar VmHWM range is 11.2-20.0 MiB, the median +is 14.6 MiB, and the large stream-copy case reaches 56.3 MiB.

The owned toolchain + translates the legacy encoding emitted by LLVM 19 for DuckDB with pinned, + checksum-verified Binaryen 128. + Disable threads/shared memory, memory64, multi-memory, relaxed SIMD, tail + calls, function references, components, custom page + sizes, and other proposals until an explicit profile revision. Engine + defaults never silently expand the accepted language. +2. **Code placement.** Kernel semantic APIs stay in `agentos-vm-kernel`. Shared + request/reply types and capability-sized host traits live under + `crates/executor-contract/src/host/`; sidecar implements them using kernel and + process-lifecycle context. Wasmtime lives in the independently feature-gated + `agentos-executor-wasm-wasmtime` crate; shared ABI/profile types live in + `agentos-executor-wasm-abi`, and only the sidecar composes concrete engines. +3. **ABI generation.** Generate Preview1 layouts/types from a checked-in pinned + Preview1 WITX description; generated glue implements agentOS host traits and + does not construct a `wasmtime-wasi` context. Generate custom-import + signatures from one checked-in agentOS ABI manifest shared by linker tests + and import-audit tooling. Handwritten code remains only for bounded memory + copying and version-to-canonical request conversion. +4. **CPU fields.** Remove the misleading lockstep `maxWasmFuel` field. Replace + it with `activeCpuTimeLimitMs` (default runaway safeguard), optional + `wallClockLimitMs`, and optional `deterministicFuel`. No compatibility alias + is needed because protocol/client/sidecar ship together. +5. **Engine profiles.** The process caches Engines by exact feature profile and + exact stack cap. Unspecified stack uses 512 KiB. Admit at most eight distinct + profiles process-wide by default, warn at 80%, and reject the ninth with a + typed limit naming the engine-profile setting. Set the async stack to the + WASM stack cap plus 1.5 MiB of host-call headroom (2 MiB for the default + profile), reject arithmetic/platform-size overflow as typed configuration + errors, and charge the complete async-stack reservation per active Store. + This preserves Wasmtime 46's default host-call headroom while making custom + stack profiles explicit and accounted. Modules never cross Engines. +6. **Module cache.** Per Engine, use a 32-entry LRU and a 256 MiB conservative + admission budget. Charge `max(module_bytes * 8, 1 MiB)` per compiled Module, + warn at 80%, never deserialize native artifacts, and expose hits, misses, + evictions, source bytes, charged bytes, compile latency, and retained RSS in + metrics. Phase 3 may tune defaults from measured evidence without changing + ownership. +7. **Platforms.** Linux x86-64, Linux arm64, macOS x86-64, and macOS arm64 are + initial release blockers because all four sidecars are published. + Full conformance and performance gates run on canonical Linux x86-64; + cross-compile plus smoke/conformance subsets run on the other three. No + browser build or browser compile repair is in scope. +8. **Preferred-backend gate.** Correctness and safety permit no regression. On + the canonical machine, Wasmtime may become preferred only when the command + corpus geometric-mean p50 regresses no more than 10%, no individual p95 + regresses more than 20%, concurrency throughput regresses no more than 10%, + and per-execution retained RSS/PSS regresses no more than the greater of 10% + or 4 MiB. VIRT is reported separately. A threshold miss keeps Wasmtime + selectable but does not make it preferred. +9. **Backend selection.** The sidecar protocol carries an optional sealed + standalone-WASM backend enum: `wasmtime` or `v8`. Omission means the + sidecar-owned default. Phase 2 initially defaults to V8; Phase 3 may switch + omission to Wasmtime after gates pass. Both clients mirror the explicit + override and neither owns the default. +10. **Threads and snapshots.** Threads/shared memory remain Phase 4 and require + a new per-thread signal/libc audit. Process isolation is decided in that + phase from teardown and containment evidence. Live snapshots/fork, Wizer, + serialized AOT artifacts, pooling, and components remain outside initial + completion. + +These decisions close the implementation questions in the parent Wasmtime +specification. A later change requires an explicit spec revision, not an +adapter-local exception. diff --git a/docs/sidebar.json b/docs/sidebar.json index 863a1bd7cf..252022dd55 100644 --- a/docs/sidebar.json +++ b/docs/sidebar.json @@ -18,6 +18,11 @@ "href": "/agentos/docs/quickstart", "icon": "faForwardFast" }, + { + "title": "Quickstart (Embedded)", + "href": "/agentos/docs/quickstart-embedded", + "icon": "faForwardFast" + }, { "title": "agentOS vs Sandbox", "href": "/agentos/docs/versus-sandbox", @@ -82,6 +87,11 @@ "title": "Resource Limits", "href": "/agentos/docs/resource-limits", "icon": "faGauge" + }, + { + "title": "Hosted Actor Limits", + "href": "/agentos/docs/actor-limits", + "icon": "faGauge" } ] }, @@ -190,6 +200,10 @@ "title": "POSIX Syscalls", "href": "/agentos/docs/architecture/posix-syscalls" }, + { + "title": "Package Architecture", + "href": "/agentos/docs/architecture/package-structure" + }, { "title": "Packages & Command Resolution", "href": "/agentos/docs/architecture/packages-and-command-resolution" @@ -230,5 +244,34 @@ } ] } + ], + "integrations": [ + { + "title": "General", + "pages": [ + { + "title": "Overview", + "href": "/agentos/integrations", + "icon": "faSquareInfo" + } + ] + }, + { + "title": "Frameworks", + "pages": [ + { + "title": "Flue", + "href": "/agentos/integrations/flue" + }, + { + "title": "Rivet Actors", + "href": "/agentos/integrations/rivet-actors" + }, + { + "title": "Vercel Eve", + "href": "/agentos/integrations/vercel-eve" + } + ] + } ] } diff --git a/docs/wasmvm/executors.md b/docs/wasmvm/executors.md new file mode 100644 index 0000000000..7fc3442850 --- /dev/null +++ b/docs/wasmvm/executors.md @@ -0,0 +1,214 @@ +# Standalone WebAssembly executors + +AgentOS has two maintained native standalone-WebAssembly engines: V8-WASM and +Wasmtime.

Threaded programs use +the owned AgentOS sysroot/libc and import `wasi.thread-spawn`; each pthread gets +its own Wasmtime Store and Instance over one group-owned `SharedMemory`. + +Before any guest code runs, admission transactionally reserves the configured +`limits.wasm.maxThreads` (including the initial thread), maximum shared-memory +envelope, table capacity, async stacks, and native thread capacity. The +per-group default is 16 threads, `limits.wasm.maxConcurrentThreads` bounds the +aggregate reservations of concurrent groups in one VM at 64 by default, and +the process-wide default is 256. Capacity failure is typed and starts no +partial group. Shared-memory growth stays within the pre-reserved maximum, and +atomics, wait/notify, and cross-Store mutation operate on the group-owned +memory. + +Signal dispositions and process-pending signals remain process-wide in the +kernel. Masks, temporary `ppoll` masks, and in-progress handler state are +per-thread; process-directed delivery deterministically selects an unblocked +thread. Trap, process exit, cancellation, timeout, `SIGKILL`, and VM disposal +terminate and reap the entire child process, including threads indefinitely +parked in `memory.atomic.wait`, without terminating the sidecar. + +The threaded libc covers mutexes, condition variables, TLS, join/detach, +thread exit, and cooperative cancellation. Live Store/Instance snapshots, +cross-engine memory, AOT artifacts, Wizer, pooling, components, and browser +execution remain unsupported. Main-thread exit tears down the group; detached +guest threads do not outlive the command. diff --git a/examples/embedded-vm/Cargo.toml b/examples/embedded-vm/Cargo.toml new file mode 100644 index 0000000000..d1cba3fdcd --- /dev/null +++ b/examples/embedded-vm/Cargo.toml @@ -0,0 +1,11 @@ +[package] +name = "agentos-example-embedded-vm" +version.workspace = true +edition.workspace = true +license.workspace = true +repository.workspace = true +publish = false +description = "Standalone executor-free agentOS embedded VM example" + +[dependencies] +agentos-vm = { workspace = true, default-features = false } diff --git a/examples/embedded-vm/src/main.rs b/examples/embedded-vm/src/main.rs new file mode 100644 index 0000000000..f7df178115 --- /dev/null +++ b/examples/embedded-vm/src/main.rs @@ -0,0 +1,48 @@ +use agentos_vm::{ExecutorRegistry, VmConfig, VmManager}; +use std::future::Future; +use std::sync::Arc; +use std::task::{Context, Poll, Wake, Waker}; + +fn main() -> Result<(), Box> { + block_on(async { + let mut manager = VmManager::builder() + .executors(ExecutorRegistry::empty()) + .build()?; + let mut vm = manager.create(VmConfig::default().allow_all()).await?; + + vm.write_file("/workspace/hello.txt", b"hello").await?; + assert_eq!( + vm.read_file("/workspace/hello.txt").await?, + b"hello".to_vec() + ); + assert!(vm.kernel()?.list_processes().is_empty()); + let snapshot = vm.kernel_mut()?.snapshot_root_filesystem()?; + assert!(!snapshot.entries.is_empty()); + vm.dispose().await?; + Ok::<_, Box>(()) + }) +} + +fn block_on(future: F) -> F::Output { + struct ThreadWake(std::thread::Thread); + + impl Wake for ThreadWake { + fn wake(self: Arc) { + self.0.unpark(); + } + + fn wake_by_ref(self: &Arc) { + self.0.unpark(); + } + } + + let waker = Waker::from(Arc::new(ThreadWake(std::thread::current()))); + let mut context = Context::from_waker(&waker); + let mut future = std::pin::pin!(future); + loop { + match future.as_mut().poll(&mut context) { + Poll::Ready(output) => return output, + Poll::Pending => std::thread::park(), + } + } +} diff --git a/examples/embedded/README.md b/examples/embedded/README.md index c1bea6f7a0..fccbd48236 100644 --- a/examples/embedded/README.md +++ b/examples/embedded/README.md @@ -5,7 +5,7 @@ category: "Reference" order: 1 --- -Use `@rivet-dev/agentos-core` to boot and control a VM directly from a trusted +Use `@rivet-dev/agentos` to boot and control a VM directly from a trusted Node.js application.

Wait for completion with `vm.process.wait(pid)`, and inspect what is running with `vm.process.list()`. ## Run it diff --git a/examples/quickstart/processes/index.ts b/examples/quickstart/processes/index.ts index c99b450842..a7c2c2a916 100644 --- a/examples/quickstart/processes/index.ts +++ b/examples/quickstart/processes/index.ts @@ -1,16 +1,17 @@ // Execute commands and manage processes inside the VM. -import { AgentOs } from "@rivet-dev/agentos-core"; +import { AgentOs } from "@rivet-dev/agentos"; const vm = await AgentOs.create(); -// Run shell commands with exec() -const result = await vm.process.exec("echo 'hello from shell'"); +// Run shell commands with exec().

VM command.** +It runs the real upstream browser against agentOS's executor host-call +contract. It is deliberately outside the shipping workspace and executor +registry. Do not pass untrusted pages to this experiment. + +The upstream source is pinned in [UPSTREAM.json](UPSTREAM.json). The browser, +DOM, network, and JavaScript implementation come from Obscura, under its +Apache-2.0 license. They are not reimplemented here. Deno is MIT-licensed. +`prepare.py` verifies both archive checksums, applies the checked-in patches, +and keeps upstream licenses in the ignored `vendor/` directory. + +## Run the fixture + +From the repository root, with Python 3.12+, GNU patch, the repository Rust +toolchain, and pnpm installed: + +```sh +pnpm install --frozen-lockfile +python3 experiments/obscura/prepare.py +cargo test --locked --manifest-path experiments/obscura/Cargo.toml +``` + +Preparation downloads pinned source archives; Cargo may download locked +dependencies and V8's build artifact. Tests use deterministic local fixtures +and make no internet requests. `--cache /path/to/cache` selects a reusable +archive cache. Generated source and binaries must not be committed. + +[tests/embedding.rs](tests/embedding.rs) is the runnable embedding example: + +1. Initialize the existing agentOS V8 platform and process Tokio driver. +2. Run Obscura's non-`Send` futures in a `LocalSet` on the calling thread. +3. Give the browser an `ExecutorBrowserHost` bound to a generation and PID. +4. Dispatch typed host requests through the bounded executor event channel. +5. Navigate virtual HTML, execute its script, and perform a JavaScript fetch. + +The fixture dispatcher returns HTML from a virtual path and HTTP responses +for `obscura.gameinc.io`. It proves transport behavior, **not** production VM +permission enforcement: it is not the kernel's production host dispatcher. +That dispatcher must own policy when a real executor is added. + +The tests cover virtual file reads, denied files and requests, policy checks +on redirect destinations, JavaScript fetch, payload rejection before admission, +queue saturation, pending-call teardown, and canceled response consumers. +They also compile WASM and run ordinary V8 JavaScript after dropping Obscura. + +Validation performed for this revision: the four experiment tests, the existing +`embedded_runtime_session` suite with `obscura-embedding` enabled, the default +`agentos-executor-v8-runtime` check, the embedded-VM dependency boundary check, +and fixed-version verification all pass. The prepared dependency graph contains +one native V8 version, 130.0.7. The full workspace and browser-conformance suites +have not been run. + +## Implemented + +- Source preparation is pinned and checksum-verified; Cargo locks dependencies. +- `ExecutorBrowserHost` submits `FilesystemOperation::ReadFileAt` and + `NetworkOperation::HttpRequest`, with bounded payloads and direct replies. +- Browser navigation and JavaScript fetch use the injected authority. Those + paths fail without it; they do not fall back to reqwest or host file reads. +- File paths remain guest paths. The host adapter does not translate them to + real host paths. HTTP requests are passed to the sidecar as typed requests. +- An optional `obscura-embedding` feature initializes Deno through the existing + process-lifetime V8 platform owner and its fixed four-worker platform. Default + V8 builds and shipping executor selection stay unchanged. + +## Compatibility patches + +Upstream uses Deno 0.412 and V8 150; agentOS uses V8 130.0.7. Linking both +native V8 libraries produced duplicate C++ symbols. This experiment ports +Obscura to Deno 0.336 and the same V8 130.0.7 used by agentOS. The patch adapts +handle scopes, op annotations, module loading, and per-realm metadata. The +fixture is not comprehensive browser-conformance coverage of that downgrade. + +Deno 0.336's async-op scheduler assumes a single-thread Tokio runtime and +marks non-`Send` futures as `Send` under that assumption. JavaScript fetch +aborted under agentOS's shared multithread runtime. The narrowly scoped +`deno-local-ops.patch` uses `tokio::task::spawn_local` instead. The embedding +must provide a `LocalSet`; it must not create a second Tokio runtime or run +guest V8 code on trusted I/O workers. This Cargo override is local to the +experiment. + +## Work required before enabling the CLI + +- Add a concrete executor adapter and registry dispatch for top-level commands, + shell/child-process launch, exec replacement, stdin/stdout/stderr, signals, + pause/resume, generation changes, and VM teardown. No such adapter is included. +- Port the real CLI's command dispatch and I/O. The upstream CLI has native + process spawning/listeners, storage and file output, and a hard timeout that + calls `std::process::exit(124)`. Those cannot execute in the sidecar unchanged. +- Replace the upstream watchdog/fallback runtime with the shared driver and + bounded guest executor. Cancellation must interrupt JS and abandon pending + host work; a Tokio timeout alone cannot stop synchronous native DOM work. +- Account for native DOM, retained resources, cookies, frames, module maps, + pending operations, and browser output. A V8 heap limit does not cover the + browser's Rust allocations. Current request caps do not solve this. +- Audit every enabled upstream native I/O and environment access. The current + patches cover navigation, files, and fetch; they are not an exhaustive audit. + CDP/MCP servers, rendering, storage persistence, and stealth transport are not + included in the prepared browser subset. +- Add actual kernel-policy and process-lifecycle integration tests and upstream + browser-conformance tests for the V8 compatibility port. Decide whether to + maintain that port or upgrade the existing V8 engine before shipping. + +These are remaining engineering tasks, not a claim that Obscura is impossible +to integrate. Registering a guest command before they are implemented would +give an incomplete and misleading security boundary. diff --git a/experiments/obscura/UPSTREAM.json b/experiments/obscura/UPSTREAM.json new file mode 100644 index 0000000000..d2e134fdae --- /dev/null +++ b/experiments/obscura/UPSTREAM.json @@ -0,0 +1,12 @@ +{ + "repository": "https://github.com/h4ckf0r0day/obscura", + "revision": "2bda71a557247bd2d6fabf01fa66eb4b07dcb2e8", + "license": "Apache-2.0", + "status": "experimental embedding port;

tests/xfstests run` is the only entrypoint. It stages the pinned +upstream xfstests revision, applies the tracked agentOS-only harness patches, +generates exact exclusions, and invokes the ignored Rust integration runner. +The run is strict: every selected test must execute and pass unless its exact +test/backend outcome has a reviewed record in `exceptions.toml`. +The runner classifies each completed case immediately and stops scheduling new +cases on the first strict violation. Already-running cases finish and tear down, +then the partial full-selection report is written before the command fails. Fix +the first reported violation with focused coverage and rerun the complete pinned +selection; a qualifying full run completes every selected case. + +## Result policy + +An upstream `notrun` is a coverage hole and fails by default. `excluded` is +reserved for tests whose subject is mount construction or mkfs administration; +correctness-relevant existing-mount policy such as read-only and atime behavior +must execute. `allowed-notrun` is reserved for an exact test/backend absence of +a named filesystem or guest-runtime feature that either does not apply to that +backend or is outside the current V8 feature-parity baseline; its literal +upstream reason must match or the run fails closed. +`deferred` is real remount/crash/fault coverage awaiting a named host hook. +`expected-failure` tests still execute and must match their normalized output +digest; an unexpected pass or changed failure is an error. `reduced` is reserved +for an exact whole-object test/backend repetition reduction with named full and +reduced counts plus focused semantic coverage; the reduced test still executes +and any non-pass outcome fails. Wildcards, +auto-blessing, unused records, duplicate records, and stale records are errors. + +Each WASM engine writes reports under `report//`: the main files +are `results.md`, `agentos-gaps.md`, and `surface-audit.md`, with +driver-specific summaries under `backends//results.md`. +`XFSTESTS_WASM_BACKENDS` defaults to the required `v8 wasmtime` executor +matrix. `XFSTESTS_BACKENDS` defaults to the +`chunked_local,memory,chunked_s3` supported writable-engine matrix and rejects +unknown or duplicate entries. The dormant `object_s3` harness paths are retained +for focused return-to-service validation, but the plugin is intentionally not +registered or user-selectable while its whole-object write-back, durability, and +request-amplification contract remains incomplete. Each enabled S3 case owns an +ephemeral local server and isolated object prefixes; it never depends on shared +cloud state. +Per-test backing roots are deleted on success, +failure, timeout, and unwind; a Make-owned run root and shell trap also cover +external cancellation. `XFSTESTS_CONCURRENCY` bounds simultaneous VMs; +`XFSTESTS_MAX_TEMP_BYTES` bounds aggregate backing storage. The default +per-test watchdog is 3,600 seconds, calibrated from the pinned helper workloads +with byte-for-byte verification enabled; +a timeout remains a strict harness failure. +The quick corpus runs `generic/011` with a reviewed 20-file reduction on every +storage backend. Nightly CI also runs the ignored full 1,000-file `dirstress` +process matrix once per WASM engine on `chunked_local`; it covers the +one-process, five-process shared, and five-process/five-directory layouts +without multiplying the saturation workload across every storage-plugin leg. +The quick corpus likewise keeps `generic/371`'s parallel `pwrite`/`fallocate` +ENOSPC race active for five iterations on every storage backend. Nightly CI +runs the upstream 100-iteration workload once per WASM engine on +`chunked_local`, separating race-endurance volume from the daily correctness +matrix without removing either concurrent operation. +The quick corpus runs `generic/404` through 20 uniquely patterned insert-range +steps and verifies the entire file after each insertion. Nightly CI runs the +upstream 500-block reproduction-probability workload once per WASM engine on +`chunked_local`; this preserves the quadratic endurance gate without putting +roughly one thousand fresh command executions in every daily storage leg. +The quick corpus runs `generic/129` for 1,620 aggregate iterations while +preserving the upstream 1000:100:500:20 ratio across its four read/write, +truncate, small-block, and open/close modes. A separate nightly endurance job +runs all 162,000 upstream iterations once per WASM engine on `chunked_local`. +The endurance job also owns the other full-volume probes, so the six +storage/backend corpus jobs cannot exhaust their timeout by serially appending +hours of unrelated stress work. + +## Correctness constraints + +- Guest commands have a shadow tree, so the runner first proves bidirectional + I/O through the mounted kernel VFS. A shadow-only result aborts the suite. +- The runner reads `/proc/mounts` in the guest and requires exactly one writable + `agentos` entry for both `/mnt/test` and `/mnt/scratch`. +- Mountpoints must exist in the kernel VFS and the guest shadow tree. +- Every test gets a fresh VM and fresh test/scratch engines. Mkfs and unmount + reset calls are scaffolding no-ops, while root-only supported remount policy is + applied to the existing mount; VM disposal is the storage reset boundary. +- `xfs_io`, `fsstress`, `fsx`, xfstests `src/` helpers, xattr tools, ACL tools, + and their syscall imports are genuine porting surfaces. Missing callers are + reported, never replaced with successful stubs. +- `/proc/mounts` must describe host-applied mounts truthfully; procfs-only + hardcoding is not acceptable. +- VM-local users and groups must use production credential transitions and DAC. + Capability policy does not bypass owner/group/other permissions. +- Teardown copies results out first, then removes metadata databases, blocks, + shadow roots, and transient result mounts. Retention is opt-in and bounded. +- The source projection is read-only while `RESULT_BASE` is a separate writable + mount. Startup probes must prove every required source/result write location. +- Toolchain or brush incompatibility is a harness failure. Harness patches may + alter mount scaffolding and device gates; helper portability patches may + replace unavailable process-launch primitives while preserving concurrency, + credentials, and exit status. No patch may weaken an assertion. +- Patch staging fails closed on the first check or apply error and always starts + by cleaning back to the pinned SHA. +- Inherited pipe readers consume bytes only when they actually read. Buffered + bytes precede EOF and each chunk has one consumer; the verify-first gate runs + an external command inside a `while read` loop to enforce this ordering. +- `_check_generic_filesystem` is a scaffolding no-op for virtual `agentos` + mounts because there is no guest-visible block format. It never suppresses + test-level corruption or data comparisons. +- Worker logs and inline report details are capped. Full bounded detail, + stdout, and stderr remain linked as raw per-test artifacts. +- Remount durability, freeze/thaw, resize, shutdown, and error injection remain + visible deferred coverage until real host lifecycle hooks exist. +- `generic/` includes Linux extensions as well as POSIX behavior. The generated + surface audit, pinned tests, and exact built helpers define the required ABI. +- The final matrix covers every writable native plugin plus bare, one-lower, + multi-lower, and meaningful mixed-engine overlay configurations separately. diff --git a/tests/xfstests/exceptions.toml b/tests/xfstests/exceptions.toml new file mode 100644 index 0000000000..3469d5ba4d --- /dev/null +++ b/tests/xfstests/exceptions.toml @@ -0,0 +1,15898 @@ +schema = 1 + +# Strict by default.

True incremental streaming needs a RAW chunk reader added to +//! `wasi-http` (its `SseReader` SSE-parses, but codex's `transport.rs` does its +//! own SSE parsing over `bytes_stream`, so the shim must surface raw bytes). +//! +//!
