Both reference agents leave file I/O untimed for the same reason. ### How each capability consumes it - **web_fetch** — the tool stays validate-and-forward; the provider's hand-rolled controller + `setTimeout` + manual listener + `finally` + `signal.reason` recovery is replaced by provider-owned `deadline`/`timeoutOf`. A pre-aborted upstream signal still throws `WEB_ABORTED` up front; otherwise `fetch` runs against the fused `d.signal`, and `translateAbortOrNetwork` classifies a thrown error by the signal (`timeoutOf` → `WEB_FETCH_TIMEOUT`, else aborted → `WEB_ABORTED`, else network → `WEB_PROVIDER_ERROR`). The public error-code contract is unchanged, and `TimeoutReason` never crosses the web seam as the public error. -- **bash** — `resolve()` clamps the request into an explicit spec. Foreground `run()` creates the deadline and passes its signal to process execution, whose existing abort listener performs the process-group kill. The executor classifies the first abort as timeout or cancellation. Background starts remain timeout-free and forward only upstream cancellation. +- **bash** — `resolve()` clamps the request into an explicit spec. Foreground `run()` creates the deadline and passes its signal to process execution, whose abort listener calls `SubprocessHandle.terminate()` and awaits the same provider-managed range. The executor classifies the first abort as timeout or cancellation. Background starts remain timeout-free and forward only upstream cancellation. - **LLM adapters** — `dsh-llm-deepseek` and `dsh-llm-pi-ai` wrap actual transport iteration with `idleWatchdog`. The five-minute configured interval covers only outstanding provider demand, not time the downstream consumer spends between chunks. The direct DeepSeek adapter also pulses that outstanding demand when its SSE parser observes a comment, without yielding the comment as a `StreamChunk` or writing it to the session log. The pi-ai SDK does not expose comment activity to its adapter, so that path can rearm only when the SDK yields. The stable signal reaches `fetch` or the SDK for the whole call, so timeout closes the underlying request and maps to `TIMEOUT`, while an earlier caller abort maps to `ABORTED`. ## Consequences -- `runBash`'s outcome no longer independently latches `timedOut` and `aborted`; a timeout and a user abort racing before process close now report a single first-abort cause instead of both being true. The uniform SIGTERM→grace→SIGKILL kill is unchanged, and the Service Definition type `ShellRunResult` keeps both booleans (now mutually exclusive), so `dsh-tool-bash`'s result rendering is untouched. +- `runBash`'s outcome no longer independently latches `timedOut` and `aborted`; a timeout and a user abort racing before process close now report a single first-abort cause instead of both being true. Timeout classification does not alter provider-owned termination: local POSIX ranges use TERM→grace→KILL, while Windows ordinary ranges terminate immediately. The Service Definition type `ShellRunResult` keeps both booleans (now mutually exclusive), so `dsh-tool-bash`'s result rendering is untouched. - `SpawnSpec.timeoutMs` and `SpawnOutcome.timedOut`/`aborted` were removed rather than kept as always-zero/always-false vestiges: with `runBash` owning no timer and the executor owning classification, they were read nowhere. An always-0 field read by nothing is dead weight under the per-file coverage gate. - web_fetch shed its bespoke controller/timer/listener/reason-recovery; the classifier now keys off the deadline signal (`timeoutOf` + `aborted`) rather than the thrown error's shape, which is robust across both the request-phase reject-with-reason and the read-phase bare-`AbortError`. - `AbortSignal.any` and `using`/`Symbol.dispose` enter the repo for the first time here (Node ≥ 24 baseline, already met). @@ -107,10 +107,10 @@ Out of scope, named to mark the boundary: `web_search` can gain an optional mode ## Alternatives considered -**A unified timeout *plugin* / `ctx.timeout` service.** Rejected on microkernel grounds.

Every target copies its native `@vscode/ripgrep` binary beside the executable as the required `-rg` sidecar; pkg runtimes select that sidecar through `process.pkg`, while ordinary Node execution uses `@vscode/ripgrep` directly. macOS uses its target prebuild and also emits the required `-spawn-helper`. All four deploy flags are grounded in measurement: `--legacy` is the mandatory path with inject-workspace-packages off; hoisted gives pkg a stable single-instance layout that the explicit materialization pass makes symlink-free; disabling automatic peer installation prevents undeclared peers from expanding the closure; link-workspace-packages selects direct workspace dependencies.

Cancellation retains the send reservation while an in-flight write settles and then signals the foreground group, so late bytes or the signal cannot target a successor; an in-flight readiness poll cannot release that reservation, and a rejected write sends no signal. The absolute deadline remains armed throughout cancellation. A signal failure becomes terminal transport failure. Completion of a stale inspection resumes polling for the current send. Startup cancellation begins terminal rollback without waiting for a stalled readiness or signalling call. Close rejects new public signals and delegates provider-managed session quiescence to the handle's awaited termination operation. ## E2B POC boundary @@ -68,6 +68,6 @@ A remote execution provider implements only its shared sandbox owner plus filesy The fundamental interfaces are wider, and a filesystem/subprocess pair must agree on one execution world.

On supported Linux hosts, the user-systemd scope retains descendants that call `setsid` or reparent, while process inspection continues to own foreground attribution and synchronous fallback evidence. Other hosts use the observational teardown: disposal sweeps descendants before and after terminating the top-level shell, waits for exact PID-identity-fenced descendants retained during foreground inspection, and retains Linux session members that survive top-level exit. macOS cannot enumerate a POSIX session after its leader exits, so a child that reparents between inspection snapshots remains an explicit local-provider limitation rather than a reason to move process mechanics back into the PTY consumer. The E2B composition demonstrates that a shared sandbox owner plus filesystem and subprocess adapters are sufficient to move the mutable coding world off-host while leaving higher capabilities provider-neutral. Its POC limits remain explicit: the SDK retains complete command transport in host memory, remote startup cannot publish a PID synchronously, exact terminal stdin-wait and independent signal facts are unavailable, numeric PID/PGID operations are not identity-fenced, the initial environment probe cannot hide unknown sandbox-default secrets from already-running same-UID processes, and adapter artifacts remain until sandbox deletion. These are provider constraints, not justification for compatibility shims or more E2B packages. diff --git a/.agents/notes/implemented/architecture/2026-07-28-portable-execution-world-consumers.zh.md b/.agents/notes/implemented/architecture/2026-07-28-portable-execution-world-consumers.zh.md index d78b04a5af..a558a5af64 100644 --- a/.agents/notes/implemented/architecture/2026-07-28-portable-execution-world-consumers.zh.md +++ b/.agents/notes/implemented/architecture/2026-07-28-portable-execution-world-consumers.zh.md @@ -18,13 +18,13 @@ Status: implemented 文件系统接口负责其他能力需要的路径事实，同时不公开其不透明目标身份：规范化进程路径、规范化 `file:` URI 和包含关系。现有完整文本与流式文本操作仍归文件系统负责；协议消费方在消费流时执行各自的保留上限。 -进程管理接口负责可执行文件查找与进程原语：以原始或收集模式 spawn 普通进程，以及 `spawnTerminal()`。终端操作是一项深层原语，其句柄负责文本 I/O、前台进程组、信号发送，以及一项须等待的 TERM→KILL 操作；该操作会结算所有在途句柄调用，并使提供方仍可观察到的每个会话成员完全停稳。其信号只取消分配；句柄一经发布，便负责自身生命周期。提示符检测、空闲推断、scrollback、沙箱策略和所有者生命周期仍由 PTY 消费方负责。 +进程管理接口负责可执行文件查找与进程原语：以原始或收集模式 spawn 普通进程，以及 `spawnTerminal()`。普通句柄把 target identity 保持为私有事实：`.done` 报告 direct target，`terminate()` 与 `waitForExit()` 则控制并观察同一个由提供方管理的范围。[原生 containment 决策](2026-08-28-subprocess-native-containment.zh.md)负责本地 Linux scope、Windows Job 及其已声明的 fallback。终端操作是一项深层原语，其句柄负责文本 I/O、前台进程组、信号发送，以及一项须等待的 TERM→KILL 操作；该操作会结算所有在途句柄调用，并使提供方拥有的范围中每个成员完全停稳；观察型 fallback 只能把该范围限制为它仍可观察到的 identity。其信号只取消分配；句柄一经发布，便负责自身生命周期。提示符检测、空闲推断、scrollback、沙箱策略和所有者生命周期仍由 PTY 消费方负责。 通用消费方使用该执行世界： - `dsh-bash-local` 继续把 Bash 语义映射到普通的 `ctx.subprocess.spawn()`。 - `dsh-lsp-stdio` 通过 `ctx.fs` 读取源文件并验证包含关系，通过 `ctx.subprocess` 解析和启动语言服务器，并让由提供方负责的文件 URI 贯穿初始化与结果渲染。一个提供方生命周期信号会在资源释放期间中止文件系统与协议操作，包括取得队列所有权之前的工作区查找；其 JSON-RPC、池化、同步和规范化保持不变。 -- `dsh-terminal-bash` 把持久 shell 语义映射到 `ctx.subprocess.spawnTerminal()`。本地 `node-pty` 与进程检查实现移入 `dsh-subprocess-local`；其他进程管理提供方则提供相同原语。`danger-full-access` 不需要 `ctx.sandbox`；受限模式要求同一执行世界中存在沙箱提供方，未挂载时会在 spawn 前失败。提供方开始写入时，系统会丢弃异步写入前检查期间收集的提示符与静默证据。取消会在在途写入结算期间保留发送预留，随后向前台进程组发送信号，因此延迟字节和该信号都无法落到后续发送；在途就绪检查无法释放该预留，写入被拒绝时也不会发送信号。绝对截止时间会在整个取消期间保持启用。信号发送失败会成为终结性传输失败。陈旧检查完成后，会针对当前发送恢复轮询。启动取消会立即开始终端回滚，而不等待停滞的就绪检查或信号发送调用。关闭操作会拒绝新的公开信号，并把提供方可观察会话成员的完全停稳委托给句柄上须等待的终止操作。 +- `dsh-terminal-bash` 把持久 shell 语义映射到 `ctx.subprocess.spawnTerminal()`。本地 `node-pty` 与进程检查实现移入 `dsh-subprocess-local`；其他进程管理提供方则提供相同原语。`danger-full-access` 不需要 `ctx.sandbox`；受限模式要求同一执行世界中存在沙箱提供方，未挂载时会在 spawn 前失败。提供方开始写入时，系统会丢弃异步写入前检查期间收集的提示符与静默证据。取消会在在途写入结算期间保留发送预留，随后向前台进程组发送信号，因此延迟字节和该信号都无法落到后续发送；在途就绪检查无法释放该预留，写入被拒绝时也不会发送信号。绝对截止时间会在整个取消期间保持启用。信号发送失败会成为终结性传输失败。陈旧检查完成后，会针对当前发送恢复轮询。启动取消会立即开始终端回滚，而不等待停滞的就绪检查或信号发送调用。关闭操作会拒绝新的公开信号，并把由提供方管理的会话完全停稳委托给句柄上须等待的终止操作。 ## E2B POC 边界 @@ -68,6 +68,6 @@ E2B 负责可变文件系统、受管命令与 Bash 进程、终端分配与终 基础接口更宽，一对文件系统／进程管理提供方必须在同一个执行世界上保持一致。新增操作仅限当前通用消费方所需的事实与生命周期机制；模型 schema、协议分帧、就绪策略和呈现不会渗入提供方。 -本地实现承接 `node-pty` 和平台进程检查，因为它负责本地终端机制。这种代码迁移不会削弱终端拆卸：dispose（资源释放）会在终止顶层 shell 前后清理后代进程，等待前台检查期间保留下来且受精确 PID 身份围栏保护的后代进程，并继续追踪在顶层进程退出后仍存活的 Linux 会话成员。macOS 无法在 POSIX 会话 leader 退出后枚举该会话，因此在两次检查快照之间重新设定父进程的子进程仍是明确的本地提供方限制，而不是把进程机制移回 PTY 消费方的理由。 +本地实现承接 `node-pty` 和平台进程检查，因为它负责本地终端机制。在受支持的 Linux 宿主上，user-systemd scope 会保留调用 `setsid` 或发生 reparent 的后代，进程检查则继续负责前台归属与同步 fallback 证据。其他宿主使用观察型拆卸：dispose（资源释放）会在终止顶层 shell 前后清理后代进程，等待前台检查期间保留下来且受精确 PID 身份围栏保护的后代进程，并继续追踪在顶层进程退出后仍存活的 Linux 会话成员。macOS 无法在 POSIX 会话 leader 退出后枚举该会话，因此在两次检查快照之间重新设定父进程的子进程仍是明确的本地提供方限制，而不是把进程机制移回 PTY 消费方的理由。 E2B 组合证明，共享沙箱所有者加上文件系统与进程管理适配器，就足以在保持上层能力与提供方无关的同时，把可变编码世界移出宿主。其 POC 限制仍明确在案：SDK 会把完整命令传输内容保留在宿主内存中；远程启动无法同步发布 PID；无法获得精确的终端 stdin 等待状态与独立信号事实；基于数值 PID/PGID 的操作没有身份围栏；初始环境探测无法向已在运行的同 UID 进程隐藏未知的沙箱默认 secret；适配器产物会一直保留到沙箱删除。这些是提供方限制，不是引入兼容性 shim 或更多 E2B 包的理由。 diff --git a/.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.i18n.yaml b/.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.i18n.yaml index 114c75c579..95ba159dbf 100644 --- a/.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.i18n.yaml +++ b/.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.i18n.yaml @@ -2,5 +2,5 @@ # side as of the last confirmed-consistent state.

A child can call `setsid`, reparent, or outlive its direct parent and leave those ranges, so terminating the apparent tree can return while work, ports, or files remain active. A direct target result also does not prove that every descendant has stopped. + +The ordinary subprocess handle cannot solve this gap by publishing a PID. Linux scope setup and the Windows Job runner establish target identity asynchronously, a PID does not name the complete managed range, and consumers would be forced to infer whether startup committed. The public result, range ownership, private startup protocol, and packaged entry therefore need separate owners. + +## Decision + +`LocalSubprocessRuntime` selects one provider-private managed-range owner before a target can execute. Eligible Linux ordinary and PTY launches enter a transient user-systemd scope; eligible Windows ordinary launches enter an unnamed kill-on-close Job owned by a private runner. Unsupported hosts use the existing weaker fallback with one provider-lifetime warning. The provider never replays a target after a selected native path may have executed it. + +An ordinary `SubprocessHandle` has no PID or public startup state. `.done` reports the direct target result or startup/provider failure, `terminate()` signals the selected range, and `waitForExit()` succeeds only after that same range is proven empty. `SubprocessTerminalHandle.pid` remains part of the terminal contract because PTY identity and foreground inspection require it. + +### Linux scope and one-shot bootstrap + +The first eligible Linux ordinary or PTY call in one runtime deeply checks the exact runner entry, the libc `execve` and `fcntl` bindings, the readable user manager, and literal-argv transient-scope support. Failed deep probes are retried, while the first success is cached. Each later eligible call still performs a lightweight user-manager reachability probe before target execution. Once selected, a scope, protocol, state-query, or pre-exec failure is reported through that launch and never switches to fallback. + +The parent creates one 0700 directory with a complete 0600 `launch-request.json` containing the final target cwd and environment. The private `DSH_SUBPROCESS_RUNNER` value locates that request while the runner starts from the provider cwd and a bootstrap-safe environment. `systemd-run --user --scope --quiet --collect --expand-environment=no` registers its process in the scope, then the one-shot bootstrap removes and validates the request, changes to the target cwd, restores the complete target environment, resolves a bare executable with the target PATH rules, clears `FD_CLOEXEC` on fd 0 through fd 2, and calls libc `execve()` with the original argv. The bootstrap becomes the target in place and preserves its inherited stdio; it does not remain as a supervisor. + +Request consumption or a manager observation of a loaded unit establishes scope ownership. Unit absence before either fact remains unresolved while the direct launcher is running. If that launcher exits while the request remains unconsumed, the direct result rejects with the startup failure while range observation records that the scope never existed and resolves the empty-range wait. The parent checks this unresolved interval every 50 milliseconds; after establishment, state queries back off exponentially to the existing 5-second systemctl bound. Each query reads both `LoadState` and `ActiveState`: loaded `inactive` or `failed`, or an established unit becoming `not-found`/`inactive` or otherwise collected away, proves the range empty. `active`, `activating`, `reloading`, and `deactivating` remain nonterminal. Unknown or malformed combinations and unreadable manager results reject `waitForExit()` instead of claiming quiescence. `terminate()` wakes a sleeping observer for an immediate recheck, and settlement cancels the losing backoff sleep. A strict sibling `startup-error.json` carries only request/bootstrap or target pre-exec failure, and the parent removes this spawn's private paths at observable lifecycle completion. + +The ordinary target result still comes from the same child process. The PTY path uses the same request and bootstrap without a resident runner, so the `node-pty` PID, process group, session leader, controlling terminal, foreground `inputWaiting`, `/dev/tty`, readiness, and direct terminal outcome retain their existing meanings while scope membership covers `setsid` and reparented descendants. + +### Windows runner and Job + +The Windows parent starts the provider runner from a bootstrap cwd and environment, gives it the original target argv after a private `--` delimiter, and waits for Node's runner `spawn` event before sending exactly one start request. A pre-spawn runner error preserves that direct launch failure while proving that no Job range existed, so the empty-range wait succeeds; post-spawn infrastructure failure remains uncertain and rejects range settlement. Node IPC otherwise carries idempotent terminate control and exactly one result. Runner fd 0 through fd 2 are isolated, fd 3 carries IPC, and fd 4 through fd 6 carry target stdin, stdout, and stderr. Fd 4 inherits the platform null-device descriptor when stdin is ignored and uses a pipe otherwise. The shared Win32 layer maps fds 4 through 6 to OS handles through Node's exported `uv_get_osfhandle()`, rejects null plus the unsigned `UV_INVALID_OS_FILE_HANDLE` and `UV_INVALID_FILE_DESCRIPTOR` sentinels exposed by Koffi, temporarily enables inheritance on valid handles, and passes them through `STARTF_USESTDHANDLES`. `spawnCurrentTokenJobProcess` requires a separately resolved `applicationName` and a complete target environment, which it sends as a sorted, double-NUL-terminated UTF-16LE block with `CREATE_UNICODE_ENVIRONMENT`, including `=X:` drive entries, without mutating the runner environment. After the suspended target enters the Job and resumes, the runner closes only fd 4 through fd 6; it never mutates or destroys Node's standard streams. The parent returns the pipe carriers as the ordinary handle's stdio, and user bytes never pass through IPC. + +The runner is the sole owner of the target process handle and unnamed Job handle. `spawnCurrentTokenJobProcess` creates the target suspended, assigns it to a kill-on-close Job that disallows active breakaway, and resumes it only after assignment. The runner polls the direct process for the target exit code and the Job for active-process count. It exits successfully only after the direct result has been delivered through the IPC send callback and the Job has reported zero active processes; the parent maps only that clean exit to successful `waitForExit()`. + +The parent permanently latches a validated numeric `target-exit` as soon as it arrives, before the existing stdout/stderr close or bounded-drain barrier settles. `.done` waits only for that stdio barrier and then returns the latched result. A later Job query, range-settlement failure, IPC loss, or abnormal runner exit rejects only `waitForExit()` and cannot replace the direct result. Infrastructure failure before a valid target result rejects `.done`, but that rejection does not reveal whether target execution began. On disconnect or result-send failure, the runner stops protocol work, terminates and closes its only Job handle, and exits nonzero. Closing the last Job handle kills remaining members but does not convert the disconnected path into a successful quiescence proof. + +### Private dispatch and protocol + +Source launches execute the package runner entry through the TypeScript source launcher, built launches resolve the `@deepseek-ai/dsh-subprocess-local/runner` export, and the Python SDK single-file executable enters through [`python/sdk-runtime/runtime-bootstrap.mjs`](../../../../python/sdk-runtime/runtime-bootstrap.mjs). The Python runtime owns that bootstrap. It calls the public CLI export when the private selector is absent; otherwise it removes the selector and dispatches to the same subprocess runner core. The public `dsh` argument parser has no hidden runner mode, `apps/cli` builds only its public entry, and packaging ships no second Node executable. + +The selector is a per-spawn locator or sentinel, not a credential or persistent format. Linux uses one strict request plus one optional strict startup-error file. Windows uses one IPC channel with closed `start` and `terminate` requests and exactly two result branches: `target-exit` with a numeric `exitCode`, and `error` with required `name` and `message` plus only optional `code`, `syscall`, and `path`; the parent derives `signal: null`. Pre-commit cancellation uses the same ordinary `error` record. The cancellation reason never crosses the wire, so a parent cancellation latch restores its first local reason exactly, including `null` or `undefined`. Missing, extra, mistyped, or unknown fields fail closed. Target environments may contain the selector name, including Windows case variants, because the provider transmits target state separately and restores it only after private selection is consumed. + +### Fallback and cleanup + +Linux falls back before target execution when the exact bootstrap, modern readable user-systemd manager, or literal-argv scope is unavailable. Windows ordinary launch falls back when the runner entry, Win32 bindings, or current-token Job probe is unavailable. macOS ordinary launch, Windows ConPTY, and other unsupported hosts retain their existing PGID, `taskkill /T`, or identity-fenced PTY observation. The warning states that descendants escaping those observable relationships are not guaranteed to terminate or delay `waitForExit()`. + +Normal Cordis disposal starts direct-result and range observation independently, requests termination, and waits for every owned range. Consumer teardown does not inspect an ordinary PID; it retains the original operation or startup error while attempting terminate and final wait, and preserves cleanup failures in the consumer's existing error order. A confirmed empty range permanently disables later signalling against stale identities. + +During a JavaScript-observable host exit, `LocalSubprocessRuntime` synchronously force-terminates every still-live handle without promises or timers. Linux sends the existing direct fallback kill and the exact scope kill; Windows kills the runner so its only Job handle closes; PTY fallback scans remain best effort. Per-handle failures are contained and do not change the host's exit result. Termination modes in which JavaScript cannot run remain outside this listener's guarantee. + +## Existing decisions and supersession + +This note owns the current native-containment mechanism. It partially updates the provider and no-PID facts in the [subprocess seam](../../archived/architecture/2026-07-26-subprocess-seam.md), the Linux teardown facts in [persistent PTY sessions](../feature/2026-07-16-persistent-pty-sessions.md), the native targets used by [synchronous host-exit cleanup](../../archived/bug-fix/2026-08-11-synchronous-subprocess-exit-cleanup.md), the ordinary consumer of [shared Win32 process primitives](../../archived/architecture/2026-08-19-shared-win32-process-primitives.md), and the private entry selected by the [Python SDK profile runtime](../../archived/architecture/2026-08-23-python-sdk-dsh-profile-runtime.md). Each note retains its other decision and remains active. + +## Verification + +- Provider and Linux protocol suites pin synchronous NUL rejection before launch side effects, strict request/error decoding, target cwd and complete environment restoration, private-variable collision, symlink-sensitive PATH traversal with preserved argv, close-on-exec removal for inherited stdio, pre-exec error ownership, failed-deep-probe retry plus successful-deep-probe caching with per-call manager checks, the three scope-establishment states including an exited launcher with an unconsumed request, `LoadState`/`ActiveState` parsing, `reloading`, terminate wake-up with losing-delay cancellation, bounded established-scope backoff, and exactly-once PTY managed-owner cleanup. +- Windows protocol and Win32 suites pin exactly two result branches, numeric-only target exits, ordinary-error start cancellation with raw parent-local reasons, the reduced `name`/`message`/`code`/`syscall`/`path` error record, the fixed `2`/`3`/`267` to `ENOENT`, `740` to `EACCES`, `5` to `EPERM`, `193` to `EFTYPE`, and remaining-code to `UNKNOWN` mapping, start delivery after runner spawn, empty-range settlement after pre-spawn failure, explicit ordinally sorted target environment blocks with `=C:` preservation and double-NUL termination, `uv_get_osfhandle()` carrier mapping and unsigned invalid-sentinel rejection, the null-device ignored-stdin carrier and piped non-ignored stdin, result-send and IPC-disconnect failures, direct-result latching before stdio settlement, active-process quiescence, and unique handle cleanup. +- Real Linux user-systemd tests run one ordinary and one `node-pty` `setsid`/reparent scenario through the production entry. They prove scope signalling and collection, bare executable lookup, escaped-descendant termination, range settlement, and unchanged PTY PID, session, controlling-terminal, foreground-input, `/dev/tty`, readiness, and startup-failure semantics. +- Native Windows tests prove suspended creation, Job assignment before resume, inherited stdio, default descendant inheritance, direct result, termination, active-process zero, abnormal/disconnected runner cleanup, kill-on-close, and synchronous host-exit termination. Source, built, and Python packaged smokes enter the same runner core. +- Public seam types, local and E2B providers, LSP and subagent consumers, shell fixtures, READMEs, the Cordis catalog, and the keyless subprocess API snapshot contain no ordinary PID; terminal PID remains. + +## Alternatives considered + +**Keep PID, make it optional, or add a public `started` promise.** Rejected because each representation exposes an asynchronous provider identity that does not name the managed range and invites consumers to infer startup or quiescence from the wrong fact. + +**Extend process-group, session, parent-tree, or PID scanning.** Rejected because a process can leave each observed relationship; broader SID signalling can also reach unrelated processes when a PTY helper shares a launcher session. Native OS membership is persistent and independently queryable. + +**Let the parent own or reopen the Windows Job.** Rejected because copied handles, named Jobs, `OpenJobObject`, process-handle handoff, and completion ports create multiple lifecycle owners without improving the direct-result contract. One runner can own target creation, Job membership, result production, and final handle closure. + +**Carry control or results through target stdio or files on Windows.** Rejected because user bytes and EOF must remain authoritative to existing Node streams, while result files or polling introduce a second result owner. One IPC channel separates control from target stdio. + +**Parse a hidden runner argument in the public CLI or ship another Node executable.** Rejected because either choice expands the public application grammar or distribution surface. A packaging-only bootstrap keeps one physical executable and two private logical entries. + +**Cache the complete Linux native decision without another reachability check.** Rejected because user-manager availability can change between spawns. The runtime caches only the first successful deep bootstrap/scope probe and lightly rechecks manager reachability for every later eligible call. + +**Recover a failed native launch by replaying the command.** Rejected because an ambiguous failure may occur after target execution and replay can therefore execute the command twice. + +## Consequences + +Supported Linux ordinary and PTY launches and Windows ordinary launches retain descendants through process-group escape and direct-parent exit, while direct target results remain independent from range quiescence. The cost is a per-spawn Linux manager check and scope/request or Windows runner/IPC/Job lifecycle, plus explicit failure when the selected owner cannot prove settlement. + +Fallback hosts continue to run commands but carry a visible weaker guarantee. Windows ConPTY, macOS native containment, active breakaway descendants, old or absent user-systemd environments, target replay, persistent runner recovery, and termination paths where JavaScript cannot execute remain outside this decision. diff --git a/.agents/notes/implemented/architecture/2026-08-28-subprocess-native-containment.zh.md

Stored event bodies reach consumers through read or write `SessionHandle` instances used by resume, query, export, fork, and continuation paths. Migrating only one consumer would let callers observe different logical generations or fail only when a later writer reaches the old file. +Session format v0 shipped in an alpha release, so a structural writer change can no longer treat existing JSONL as disposable pre-release state. The first whole-artifact migration implementation made those logs convertible, but its data model turned a 116 MB real Session into an operation that exhausted a 16 GB Node process before returning a handle. -Migration must retain the exact source path, bytes, and inode, including a torn physical tail, while giving every published format one unambiguous canonical filename. Plain JSONL and Zstandard are encoding choices for the same logical format and must not create parallel migration implementations. +### Whole-artifact performance failure + +- Zstandard input was split into 317,540 frames and each frame used a separate asynchronous decompression call. The implementation retained every plaintext frame and then concatenated them before JSON parsing, creating the same number of Promise, thread-pool, and native decode transitions. +- Physical Decode materialized a complete plaintext Buffer, one complete string, every JSONL row, expanded source events, migrated target events, encoded target rows, a joined target string, and target physical Buffers at overlapping points in the same request. +- Every codec and migration edge called `snapshotSessionFormatJson()` or `snapshotSessionFormatArtifact()`. These operations detached, recursively copied, and deeply froze whole headers, rows, payloads, and event arrays before and after adjacent migrations. +- Released packed Assistant chunks expanded into about 9.14 million logical v0/v1 events before v1-to-v2 folded them into 72,784 current events. The whole-artifact API required both representations and the old-to-new sequence map to coexist. +- Encoding built the complete JSONL and compressed output in memory. The successful path then decoded the staged target, decoded the committed target, and decoded it again in persistence to construct the business object; it also reread the source for a full fingerprint comparison. +- Per-frame `await` calls did not provide useful bounded scheduling. The pre-migration reader instead reused one synchronous decoder and yielded from the outer loop about every 500 ms, avoiding hundreds of thousands of asynchronous transitions. + +### The interfaces prevented local fixes from composing + +`SessionFormatCodec` decoded and encoded complete arrays, each adjacent `SessionFormatMigration` accepted and returned a complete `SessionFormatArtifact`, and the compiled chain could only hand one materialized artifact to the next edge. A faster physical decoder therefore still encountered source-row arrays, expanded-event arrays, per-edge snapshots, and target-row arrays downstream. + +The migrations are stateful even though the API presented them as one-shot functions. v0-to-v1 tracks message and retry identity. v1-to-v2 buffers one unsettled Assistant attempt, tracks events blocked behind it, and maintains old-to-new sequence references. Wrapping that state in closures or push/finish helper objects made the runtime structure different from the static declarations and made production, Worker verification, fixtures, and replay use different entry paths. ## Decision -`SESSION_FORMAT_VERSION` is a monotonic current-writer integer. One profile-independent pure package owns each adjacent `vN -> vN+1` conversion. `@deepseek-ai/dsh-session-format` supplies only lossless snapshots, unique gap-free planning, header-only conversion, and whole-artifact composition; `@deepseek-ai/dsh-session-format-catalog` statically imports the complete chain independently of mounted Cordis plugins. Historical codecs and normalizers live in the named edge package, while current Session and persistence code accept only the latest logical types. +The Session format packages use a stateful synchronous Stage API. Static migration declarations describe one adjacent version edge and create a new stage for each restored artifact. A stage owns that artifact's mutable state; no stage instance is shared across Sessions. -Each edge freezes strict source and target semantics, while its target physical codec remains vocabulary-neutral so ordinary event growth can stay within one format version. The catalog restores the final generation through the installed peer `@deepseek-ai/dsh-session` and its current `KNOWN_SESSION_EVENT_TYPES`, preventing a frozen historical edge from becoming the current vocabulary owner. +### Stage and Context protocol -The JSONL provider completes ensure-current work before `open` returns a handle for a stored Session. It selects the highest canonical generation, migrates a supported historical body, and decodes the current result from one physical snapshot; the public `SessionPersistence` and `SessionHandle` interfaces contain no migration operations. Header-only `stat` and `list` rescan Session directories, translate supported historical headers in memory, and never publish a successor. `create` checks canonical filenames independently of header readability, so every existing generation reserves its Session id. +```text +interface SessionFormatMigrationContext { + emitEvent(event: SessionFormatEvent): void + emitRun(run: SessionFormatEventRun): void +} -Cancellation belongs to the `open`, `stat`, or `list` call that supplied it. Discovery, stable reads, decoding, and pre-publication checks observe that signal; once an immutable successor is published and its directory entry is synced, later cancellation does not delete the committed generation. +interface SessionFormatMigrationStage { + readonly headerInheritedEventCount?: number + transformEvent( + event: SessionFormatEvent, + context: SessionFormatMigrationContext, + ): void + transformRun( + run: SessionFormatEventRun, + context: SessionFormatMigrationContext, + ): void + finish(context: SessionFormatMigrationContext): number +} +``` -The configured JSONL encoding owns one full suffix, `.jsonl` or `.jsonl.zstd`. Migration reads a stable exact source, decodes the recoverable logical prefix, composes every required edge in memory, validates and syncs a same-directory temporary stage for only the final target, rechecks the source fingerprint, publishes that previously absent target without overwrite, syncs the namespace, and reopens it through current validation before returning a handle. The source never moves or changes; only disposable temporary stages may be moved, linked, or removed. Migration does not synthesize interrupted-turn events: agent-loop appends those repairs through the write handle, while read-only query paths balance them in memory. +`SessionFormatMigrationContext.emitEvent()` and `emitRun()` are synchronous. The producer declares whether it emits a scalar event or a compact run, so the hot path never infers the category from properties on a parsed file object. The caller owns scheduling and supplies the context to each operation instead of injecting a callback into the stage constructor. One input may emit zero, one, or many outputs without allocating a temporary return array or retaining an internal output queue. -Canonical filenames encode the physical format generation: v0 is `session.jsonl` or `session.jsonl.zstd`; every positive generation is lowercase `session.vN.jsonl` or `session.vN.jsonl.zstd`. `dsh-session-format` owns the raw basename rule (`sessionFormatLogFilename`, `parseSessionFormatLogFilename`); the JSONL provider, the session-log export archive, and recorded-session fixtures append only the compression suffix. Publication never renames, replaces, or deletes a committed generation path. If the target already exists, it is accepted only as a regular current-format file with exactly the expected bytes; any other target refuses. Lower generations remain for operator inspection or explicit copying, but normal runtime operations select the numerically highest canonical name and never use retained predecessors as automatic fallback, restore, or downgrade support. +`SessionFormatMigration` remains an immutable declaration: version numbers, header migration, target-header validation, and `createStage()`. `CompiledSessionFormatChain` validates a unique gap-free edge sequence once, creates per-artifact stages in source-to-target order, and connects them with context objects in reverse order. `finish()` settles stages in source-to-target order so each stage can emit its tail before the downstream stage closes. -The current-format fast path classifies the header from one stable source snapshot, invokes no historical converter or generation write, and passes that snapshot to current decoding without another file read. The decoded log enters the existing bounded revision-keyed memo for an immediate observe-to-resume handoff, while `stat` and `list` deliberately rescan. Multiple edges leave the original generation unchanged and publish only the final target; intermediate versions exist only in memory. A source fingerprint recheck restarts migration when content changes, and exclusive target publication accepts a racing winner only when its bytes match exactly. Cross-process append fencing remains outside this guarantee. +```text +JSONL record + → released physical row decoder + → v0-to-v1 stage + → v1-to-v2 stage + → current event collector +``` -The first edge, `@deepseek-ai/dsh-session-format-v0-to-v1`, is intentionally identity-shaped: aside from the version and bounded historical normalizations already accepted by v0, it preserves logical headers, events, sequence numbers, references, timestamps, payloads, and the configured compression choice. The exact `session.jsonl[.zstd]` source remains byte- and inode-identical, while the current writer encodes the new `session.v1.jsonl[.zstd]` successor. This exercises the complete publication lifecycle before a cardinality-changing format needs it. +The chain contains no `flatMap`, spread expansion, intermediate event array, or scheduler. The final event collector expands a compact run only after every migration stage has had the opportunity to consume it directly. -Projection-cache records bind their fold to the Session header's `formatVersion`. The `session_projcache` v7 reader may load predecessor domain records structurally, but a record without the format generation cannot seed a current Session; the authoritative log refolds it and the next checkpoint writes the complete current identity. This prevents a cache row produced before a bounded normalizer or cardinality-changing edge from bypassing that migration. +### Physical codecs and packed runs -## Consequences +Each released codec creates a row decoder with explicit `strict` or `recoverable` recovery. The decoder validates and emits one event or one codec-owned `SessionFormatEventRun` at a time through separate context methods. v0-to-v1 and v1-to-v2 implement both `transformEvent()` and `transformRun()`, so packed Assistant chunks can reach the folding edge without first becoming millions of ordinary events. -Reading event bodies with a newer build may durably add a higher generation. The exact old generation remains available, but the runtime thereafter selects the highest canonical filename; retention does not promise that an older build can safely downgrade or that the newer build will fall back when the successor is corrupt. A read-only filesystem reports an actionable migration failure instead of returning an in-memory current view that differs from disk. +The v0-to-v1 edge preserves logical headers, sequence numbers, references, timestamps, and payloads except for bounded released-v0 normalizations. It translates the retired `steering/message` and `compact/*` event names, accepts a released `llm/retry` after its matching `step/end`, deterministically supplies a missing `llm/retry.retryId` per turn/step/provider/policy chain, and supplies one deterministic `compactionId` across a legacy compaction group that omitted it. The v1-to-v2 edge owns attempt folding and reference remapping, and emits only settled current events. It splits a legacy goal-sourced user message into `goal/change` plus the original model-visible message. It also inserts an interrupted `turn/end` for the bounded released restart in which an open turn with no open step is followed by a non-empty `next-turn` inbox splice and the next numbered `turn/start`. -JSONL publication uses POSIX hard-link creation plus directory sync, and Windows uses no-overwrite `MoveFileExW` with write-through. A competing writer that wins target creation is accepted only when the committed bytes exactly match. One process-local writer per Session is the supported concurrency model. A future per-Session cross-process lock can close the remaining source-check-to-publication race without changing the format edge interface. +The catalog exposes one `createRestore()` operation for production, Worker, fixture, and replay callers. Recovery policy and final validation policy are chosen once at restore creation. Historical production uses recoverable source parsing with transformed-current validation; this validates the released current result after migration, while input that is already current receives only codec validation. Worker and fixture verification use strict parsing with full installed current restoration. A migration-stage or transformed-current validation refusal remains `SessionFormatUnsupportedMigrationError`; physical decoding failures remain corruption. Test support keeps only fixture-specific token and envelope materialization. -Retained generations are not a live-stream write-ahead log. A future optional WAL sidecar may preserve unfinished assistant streams across a hard crash. Explicit generation inspection or copying, retention tooling, compression conversion, and streamed whole-artifact transformation are separate features; automatic fallback and downgrade compatibility are not implied future work. +### JSONL integration -This note supersedes the continue-only persistence rule and the deferred-chain status in [Session log versioning](2026-08-10-session-log-version-mechanism.md). That note remains the authority for when to bump the version and for ordinary equal-version `ignorable` event behavior. +The JSONL provider scans frame boundaries once, reuses one Zstandard decoder, parses complete JSONL records incrementally, and feeds rows directly into the catalog restore. The outer loop yields at a bounded cadence; there is no per-frame `await` and no complete plaintext or source-row array. + +Current encoding is record based. The provider serializes about 1 MiB of plaintext per main-thread slice, streams it through one Zstandard context with source-error propagation, writes compressed output in 4 MiB batches to an exclusively created same-directory temporary file, and syncs it before publication. A process-wide scheduler admits at most two full verification Workers and hands a released permit directly to the oldest waiter. + +Preparation forwards cancellation through source reads and observes it at the existing approximately 500 ms Decode yield boundary. Once `publish()` starts, encode, Worker verification, and publication do not receive caller cancellation and run to settlement; write open checks its caller signal again afterward. A published generation is never rolled back. + +The Stage pipeline ends at one prepared current artifact. [Historical Session read preparation](2026-09-05-read-only-session-migration-preparation.md) defines how read open consumes that artifact immediately while write open performs encode, verification, and publication before returning append access. + +### Durable format and publication rules + +Canonical filenames encode physical format generation: v0 is `session.jsonl[.zstd]` and positive generations use `session.vN.jsonl[.zstd]`. Migration never moves, replaces, or deletes a committed generation and writes only the final current target; intermediate versions exist only as stage state. + +POSIX publication uses hard-link creation plus directory sync. Windows uses no-overwrite, write-through `MoveFileExW`. An existing target is accepted only when its verified migration prefix equals the staged bytes; any append tail belongs to current-generation reading rather than migration winner verification. + +Existing write handles retain the process-local claim and kernel-backed cross-process `SessionWriteLease`. Header-only `stat` and `list` translate supported historical headers without opening the body or publishing a generation. Projection-cache records bind their fold to the Session header's format version so a cache row cannot bypass a cardinality-changing migration. + +## Problem-to-solution mapping + +| Whole-artifact problem | Implemented mechanism | Result | +|---|---|---| +| One asynchronous decode call per Zstandard frame | One reusable decoder; outer 500 ms scheduling cadence | Removes 317,540 async transitions | +| Complete plaintext, string, and row arrays | Incremental JSONL parser and row decoder | Retains only one cross-chunk record fragment | +| Complete event array between every edge | Context-connected stateful stages | No intermediate version event arrays | +| Packed chunks expand before folding | `SessionFormatEventRun` plus `transformRun()` | 9.14 million source events need not materialize | +| Whole-artifact snapshot and deep freeze at every edge | Stage-owned exclusive values and final validation | Removes repeated recursive copy/freeze | +| One-shot migration functions hide state | Per-artifact stage classes from immutable declarations | State ownership and concurrency are explicit | +| Bulk current encode builds whole strings and Buffers | Record encoder, 1 MiB input slices, 4 MiB write batches | Bounds allocation and main-thread slices | +| Verification repeats on the main thread | At most two complete-generation Workers | Keeps verification CPU off the main thread | +| Production and fixture migration use different APIs | Catalog `createRestore()` with explicit policies | One decoder/chain implementation | ## Verification -Release verification runs the committed Session-format corpus gate over every versioned persisted-or-projected `session*.jsonl` fixture under `snapshots/`, `packages/`, and `scripts/snapshots/python-sdk-single-exe/`. Fixture-only omitted envelopes and request-header tokens are materialized before the real static catalog; every fixture reaches the current v1 view through current restoration or historical migration. Released-v0 replay inputs remain suffixless, while fresh v1 writer outputs use `session.v1.jsonl` for a parent and `session..v1.jsonl` for children. Record and refresh preserve every completed generation, including generations of a child role absent from a later run. Malformed historical fixtures are repaired at their source rather than admitted through path-dependent replay policy. The continuing gate discovers the corpus dynamically and fails every restoration refusal; separate assembled JSONL tests own exact physical-byte migration. +### Benchmark input and meanings -Handle-integration verification runs the pure format, catalog, persistence-seam, and JSONL provider suites together: 420 tests cover both encodings, immutable publication races, header-only observation, read and write handles, migration refusal, append after migration, cancellation, and crash-tail behavior with per-file 100% statement, branch, function, and line coverage. Repository typecheck and lint, 113 keyless recorded-session replays with two declared skips, and 28 owner-local expected-output cases also pass on the merged master checkpoint. +The benchmark uses Node v24.18.0 and one 116,228,655-byte v0 Zstandard log containing 317,540 frames and 454,151 physical rows. The old reader restores 9,143,111 expanded v0 events. Migration produces 72,784 current v2 events with artifact SHA-256 `fa16ff9472ca350595a3112c20a3db79655bc2673973469987ecaf2a57ebd17c`. -The assembled headless profile test stages `session.jsonl`, resumes it through the shipped composition, observes v1 before Session construction, verifies that the exact v0 bytes and inode remain while `session.v1.jsonl` appears, and proves the next append targets v1. JSONL contract tests exercise raw and Zstandard exclusive publication, torn-tail preservation, source changes, target collisions, future-highest refusal, revision-keyed parsed-log reuse, listing rescans, temporary cleanup, committed reopen, and current-format bypass. +Runs use built artifacts under plain Node, one process per sample, and a 16 GB V8 heap limit. “Retained heap” is measured after forced GC while the restored Session remains live.

The Stage architecture removes full source and intermediate target arrays; it does not promise memory proportional to a page window. + +Decoded scalar `assistant/chunk` rows receive envelope validation and final target validation, but their complete frozen-v1 source payload-member validation is deferred because that per-event check materially affects Decode and migration time on released logs.

Retention does not promise downgrade compatibility, automatic fallback, or that an older runtime can safely interpret a newer generation. ## Alternatives considered -- **Migrate only on continuation** — leaves query, export, fork, and suffix consumers on old generations and duplicates restoration policy. -- **Return a migrated in-memory view without persisting** — lets one process observe state that does not match the highest committed generation and postpones failure until a later writer. -- **Persist every intermediate version** — consumes space and creates recovery states with no runtime consumer; only the source and final generation are durable. -- **Let mounted event-owner plugins register migrations** — makes historical readability deployment-dependent; the static catalog must work before feature plugins mount. -- **Reuse one filename for every current format and relocate its predecessor** — rejected because migration would move or overwrite committed evidence, require collision and retention rules, and make the filename disagree with the stored format. Canonical immutable generation names let discovery select the highest version directly. +- **Optimize only Zstandard Decode** — restores physical Decode speed but leaves source rows, expanded events, snapshots, intermediate artifacts, and bulk encode in memory. +- **Synchronous Generator stages** — retain execution frames and batches at each yield. Real-log measurements increased migration time and migrate-complete RSS from about 1.0 GB to about 1.2 GB. +- **Return arrays from each stage** — preserves the old allocation, traversal, and flattening costs under a new name. +- **Give each stage an internal output queue** — adds drain, EOF, and error ownership while still retaining intermediate values. +- **Inject an emit callback through constructors** — forces reverse construction or a partially connected lifecycle. Passing a context to operations keeps stage construction independent of downstream wiring. +- **Share stateful codec instances globally** — would mix pending attempts, mappings, and counters across concurrent Session restores. +- **Persist every intermediate format version** — creates durable states with no runtime consumer; only the exact source and final current generation are needed. +- **Let mounted plugins register migrations** — makes historical readability deployment dependent. The static catalog must restore released formats before feature plugins mount. diff --git a/.agents/notes/implemented/architecture/2026-08-31-released-session-format-migrations.zh.md

是同一逻辑格式的编码选择，不能产生两套并行迁移实现。 +### Whole-artifact 性能问题 + +- Zstandard 输入包含 317,540 个 frame，每个 frame 都单独执行一次异步解压。实现先保留全部 plaintext frame，再在 JSON 解析前统一拼接，因此创建了同等数量的 Promise、线程池与 native Decode 调度。 +-

Decode 与 Encode；每条相邻 `SessionFormatMigration` 接收并返回完整 `SessionFormatArtifact`；compiled chain 只能把已经物化的 artifact 交给下一条 edge。因此即使 physical decoder 单点变快，下游仍会重新创建 source-row array、expanded-event array、逐 edge snapshot 与 target-row array。 + +Migration 实际有状态，但 API 把它们表现为一次性函数。v0-to-v1 需要跟踪 message 与 retry identity；v1-to-v2 需要暂存一个尚未结算的 Assistant attempt、被它阻塞的后续事件，并维护 old-to-new seq 引用。把这些状态隐藏在 closure 或 push/finish helper object 中，会让运行结构与静态声明分离，也让 production、Worker verify、fixture 与 replay 使用不同入口。 ## 决策 -`SESSION_FORMAT_VERSION` 是单调递增的当前 writer 整数。每个相邻 `vN -> vN+1` 转换由一个与 profile 无关的纯包负责。`@deepseek-ai/dsh-session-format` 只提供无损快照、唯一且无缺口的规划、仅 header 转换与整产物组合；`@deepseek-ai/dsh-session-format-catalog` 静态导入完整链，不依赖已挂载的 Cordis 插件。历史 codec 和归一化器位于具名迁移边包中，而当前 Session 与持久化代码只接纳最新逻辑类型。 +Session format 包采用有状态同步 Stage API。静态 migration declaration 描述一条相邻版本边，并为每次 artifact restore 创建新的 stage。Stage 拥有该 artifact 的可变状态；不同 Session 之间绝不共享 stage instance。 -每条迁移边都会冻结严格的源与目标语义，其目标物理 codec 则保持词汇中立，使普通事件增长可以留在同一格式版本内。目录通过已安装的 peer `@deepseek-ai/dsh-session` 及其当前 `KNOWN_SESSION_EVENT_TYPES` 还原最终代，避免冻结的历史迁移边反过来成为当前词汇 owner。 +### Stage 与 Context 协议 -JSONL provider 在 `open` 为已存储 Session 返回句柄前完成 ensure-current 工作。它选择最高规范 generation、迁移受支持的历史正文，并从同一物理快照解码当前结果；公开 `SessionPersistence` 与 `SessionHandle` 接口不包含迁移操作。仅 header 的 `stat` 与 `list` 会重新扫描 Session 目录，在内存中转换受支持的历史 header，且绝不发布后继。`create` 独立于 header 可读性检查规范文件名，因此每个现有 generation 都会占用其 Session id。 +```text +interface SessionFormatMigrationContext { + emitEvent(event: SessionFormatEvent): void + emitRun(run: SessionFormatEventRun): void +} -取消属于提供信号的 `open`、`stat` 或 `list` 调用。发现、稳定读取、解码与发布前检查都会观察该信号；不可变后继一旦发布且其目录项已经同步，后续取消不会删除已提交 generation。 +interface SessionFormatMigrationStage { + readonly headerInheritedEventCount?: number + transformEvent( + event: SessionFormatEvent, + context: SessionFormatMigrationContext, + ): void + transformRun( + run: SessionFormatEventRun, + context: SessionFormatMigrationContext, + ): void + finish(context: SessionFormatMigrationContext): number +} +``` -配置的 JSONL 编码拥有一个完整后缀：`.jsonl` 或 `.jsonl.zstd`。迁移读取稳定的精确源，解码可恢复逻辑前缀，在内存中组合全部必需迁移边，只为最终目标校验并同步同目录临时 stage，重新检查源 fingerprint，以不覆盖方式发布此前不存在的目标，同步 namespace，并在返回句柄前通过当前格式校验重新打开。源永不移动或改变；只有可丢弃临时 stage 可以被移动、链接或移除。迁移不会合成中断轮次事件：agent-loop 通过写句柄追加这些修复，而只读查询路径在内存中补齐它们。 +`SessionFormatMigrationContext.emitEvent()` 与 `emitRun()` 都是同步操作。Producer 会声明其发出单个事件还是紧凑 run，因此热路径不会根据已解析文件对象的属性推断类别。调度归 caller 所有，context 在每次调用时传入，而不是把 callback 注入 stage constructor。一个输入可以输出零个、一个或多个值，不需要分配临时返回数组，也不需要 stage 内部保留输出队列。 -规范文件名编码物理格式 generation：v0 是 `session.jsonl` 或 `session.jsonl.zstd`；每个正 generation 都是小写 `session.vN.jsonl` 或 `session.vN.jsonl.zstd`。`dsh-session-format` 拥有原始 basename 规则（`sessionFormatLogFilename`、`parseSessionFormatLogFilename`）；JSONL provider、session-log 导出归档与 recorded-session fixture 只追加压缩后缀。发布绝不重命名、替换或删除已提交 generation 路径。目标已经存在时，只有它是普通当前格式文件且字节与预期完全相同时才接受；其他目标都会拒绝。低 generation 为 operator 检查或显式复制而保留，但普通 runtime 操作选择数值最高的规范名称，绝不把保留的前任当作自动 fallback、restore 或 downgrade 支持。 +`SessionFormatMigration` 继续作为 immutable declaration，声明版本号、header migration、target-header validation 与 `createStage()`。`CompiledSessionFormatChain` 只校验一次唯一、无缺口的 edge 序列，按 source-to-target 顺序创建每次 artifact 独占的 stage，再按反方向用 context 连接它们。`finish()` 按 source-to-target 顺序关闭 stage，使每一级都能在下游关闭前发出尾部数据。 -当前格式快速路径从一个稳定源快照分类 header，不调用历史 converter，不写 generation，并把该快照交给当前格式解码，而不再次读取文件。解码日志进入现有按 revision 为键的有界 memo，供紧接的观察到恢复交接复用，而 `stat` 与 `list` 会有意重新扫描。多条迁移边保持原 generation 不变，并只发布最终目标；中间版本只存在于内存。源 fingerprint 重新检查会在内容变化时重启迁移，排他目标发布只在竞争胜者字节完全相同时接受它。跨进程 append 隔离不在此保证内。 +```text +JSONL record + → released physical row decoder + → v0-to-v1 stage + → v1-to-v2 stage + → current event collector +``` -第一条迁移边 `@deepseek-ai/dsh-session-format-v0-to-v1` 有意保持恒等形态：除版本和 v0 已接纳的有限历史归一化外，它保留逻辑 header、事件、序号、引用、时间戳、payload 与已配置的压缩选择。精确的 `session.jsonl[.zstd]` 源保持字节与 inode 相同，当前 writer 则编码新的 `session.v1.jsonl[.zstd]` 后继。这样可在出现改变基数的格式前先验证完整发布生命周期。 +Chain 中不存在 `flatMap`、spread expansion、中间 event array 或 scheduler。只有在每个 migration stage 都已获得直接消费 compact run 的机会后，最终 event collector 才会展开它。 -投影缓存记录把自己的折叠结果绑定到 Session header 的 `formatVersion`。`session_projcache` v7 reader 可以在结构上载入前代 domain 记录，但缺少格式代的记录不能播种当前 Session；权威日志会重新折叠它，下一次检查点写入完整的当前 identity。这样，任何在有界规范化或基数变化边之前产生的缓存行都不能绕过该迁移。 +### Physical codec 与 packed run -## 后果 +每个 released codec 会用显式 `strict` 或 `recoverable` 策略创建 row decoder。Decoder 每次通过不同的 context 方法校验并 emit 一个 event 或 codec-owned `SessionFormatEventRun`。v0-to-v1 与 v1-to-v2 都实现 `transformEvent()` 和 `transformRun()`，因此 packed Assistant chunk 可以直接到达 folding edge，无需先变成数百万个普通事件。 -较新 build 读取事件正文时可能持久增加一个更高 generation。精确旧 generation 仍然可用，但 runtime 此后选择最高规范文件名；保留不承诺旧 build 能安全 downgrade，也不保证新 build 在后继损坏时 fallback。只读文件系统会报告可操作的迁移失败，而不会返回与磁盘不一致的内存当前视图。 +v0-to-v1 除了有限的 released-v0 归一化外，会保留逻辑 header、seq、引用、时间戳与 payload。它转换已移除的 `steering/message` 与 `compact/*` 事件名称，接受出现在对应 `step/end` 之后的已发布 `llm/retry`，按 turn／step／provider／policy chain 为缺失的 `llm/retry.retryId` 确定性补值，并为省略 id 的旧 compaction group 确定性补充同一个 `compactionId`。v1-to-v2 负责 attempt folding 与引用重写，并且只 emit 已结算的 current event。它会把旧的 goal 来源 user message 拆成 `goal/change` 与原本的模型可见 message。它还会为一种有限的已发布 restart 插入 interrupted `turn/end`：一个没有 open step 的 open turn 后出现非空 `next-turn` inbox splice，随后直接开始编号连续的下一轮。 -JSONL 发布在 POSIX 上使用硬链接创建与目录同步，在 Windows 上使用 write-through 且不覆盖的 `MoveFileExW`。竞争 writer 已先创建目标时，只有已提交字节完全匹配才接受。每个 Session 只支持一个进程内 writer。未来逐 Session 跨进程锁可以关闭剩余的源检查到发布竞态，而无需改变格式迁移边接口。 +Catalog 为 production、Worker、fixture 与 replay 暴露同一个 `createRestore()`。Recovery policy 与最终 validation policy 在 restore 创建时一次确定。Historical production 使用 recoverable source parsing 与 transformed-current validation；这种策略会在迁移后校验已发布 current 结果，而已经是 current 的输入只接受 codec 校验。Worker 与 fixture verification 使用 strict parsing 与已安装 current 格式的完整 restoration。Migration stage 或 transformed-current validation 的拒绝会保持为 `SessionFormatUnsupportedMigrationError`；物理解码失败仍是 corruption。Test support 只保留 fixture 自身需要的 token 和 envelope materialization。 -保留的 generation 不是实时流 WAL。未来可选 WAL sidecar 可以在硬崩溃间保留未完成 assistant 流。显式 generation 检查或复制、保留策略工具、压缩转换与流式整产物转换都是独立功能；自动 fallback 与 downgrade compatibility 并非隐含 future work。 +### JSONL 串联 -本记录取代 [Session 日志版本机制](2026-08-10-session-log-version-mechanism.zh.md) 中仅在继续时持久化和迁移链仍推迟的规则。原记录继续负责何时递增版本，以及普通同版本 `ignorable` 事件行为。 +JSONL provider 只扫描一次 frame boundary，复用一个 Zstandard decoder，增量解析完整 JSONL record，并把 row 直接送入 catalog restore。外层循环按有界 cadence yield；不存在逐 frame `await`、完整 plaintext 或 source-row array。 + +Current encode 以单条 record 为单位。Provider 在主线程每个 slice 序列化约 1 MiB plaintext，通过一个会传播 source error 的 Zstandard context 流式压缩，以 4 MiB batch 写入同目录排他创建的临时文件，并在 publication 前 sync。进程级 scheduler 最多允许两个完整 verification Worker 并行，并把释放的 permit 直接交给最早的 waiter。 + +Preparation 会把 cancellation 传给 source read，并在现有的约 500 ms Decode yield 边界观察它。`publish()` 一旦开始，encode、Worker verification 与 publication 不接收 caller cancellation，并运行到终态；write open 会在之后再次检查 caller signal。已经发布的 generation 绝不会回滚。 + +Stage pipeline 终止于一份 prepared current artifact。[历史 Session 只读迁移准备](2026-09-05-read-only-session-migration-preparation.zh.md)定义 read open 如何立即消费该 artifact，以及 write open 如何在返回 append 权限前完成 encode、verification 与 publication。 + +### Durable format 与 publication 规则 + +规范文件名编码 physical format generation：v0 使用 `session.jsonl[.zstd]`，正 generation 使用 `session.vN.jsonl[.zstd]`。Migration 不会移动、覆盖或删除任何 committed generation，并且只写最终 current target；中间版本只存在于 stage state。 + +POSIX publication 使用 hard-link creation 加目录 sync；Windows 使用 no-overwrite、write-through 的 `MoveFileExW`。已有 target 只有在其已校验 migration prefix 等于 staged bytes 时才会被接受；任何 append tail 都属于 current-generation reader，而不是 migration winner verification。 + +既有 write handle 继续使用进程内 claim 与内核支持的跨进程 `SessionWriteLease`。仅 header 的 `stat` 与 `list` 可以转换受支持的历史 header，但不打开 body，也不发布 generation。Projection-cache record 会把 fold 绑定到 Session header 的 format version，使 cache row 不能绕过改变 event 基数的 migration。 + +## 问题与方案对照 + +| Whole-artifact 问题 | 实现机制 | 结果 | +|---|---|---| +| 每个 Zstandard frame 单独异步 Decode | 一个可复用 decoder；外层 500 ms 调度 cadence | 删除 317,540 次异步切换 | +| 完整

考虑过的替代方案 -- **只在继续时迁移**——让查询、导出、分叉与后缀消费者停留在旧代际，并重复恢复策略。 -- **返回迁移后的内存视图但不持久化**——让进程观察到与最高已提交 generation 不一致的状态，并把失败推迟到后续 writer。 -- **持久化每个中间版本**——消耗空间并产生没有 runtime 消费者的恢复状态；只有源与最终代际应持久。 -- **让已挂载事件 owner 插件注册迁移**——使历史可读性依赖部署；静态 catalog 必须在功能插件挂载前工作。 -- **让每个当前格式复用同一个文件名并迁走前任**——不予采用，因为迁移会移动或覆盖已提交证据，需要冲突与保留规则，并让文件名与存储格式不一致。规范不可变 generation 名让发现流程直接选择最高版本。 +- **只优化 Zstandard Decode**——可以恢复 physical Decode 速度，但 source rows、expanded events、snapshot、intermediate artifact 与 bulk encode 仍会留在内存中。 +- **同步 Generator stage**——每个 yield 都会保留执行帧与 batch。真实日志测量使 migration 更慢，并让 migrate-complete RSS 从约 1.0 GB 增长到约 1.2 GB。 +- **每个 stage 返回数组**——只是给旧的 allocation、遍历与 flattening cost 换了名字。 +- **Stage 内部输出队列**——增加 drain、EOF 与 error ownership，同时仍会保留中间值。 +- **通过 constructor 注入 emit callback**——迫使 chain 反向构建或引入 partially connected lifecycle。操作时传 context 可以让 stage construction 不依赖下游 wiring。 +- **全局复用有状态 codec instance**——会让不同 Session 的 pending attempt、mapping 与 counter 相互污染。 +- **持久化每个中间格式版本**——产生没有 runtime consumer 的 durable state；只需要精确 source 与最终 current generation。 +- **让 mounted plugin 注册 migration**——使历史可读性依赖部署。Static catalog 必须在 feature plugin 挂载前恢复已发布格式。 diff --git

+JSONL backend 将 logical preparation 与 durable publication 分开。Read open 只等待 preparation；write open 复用 matching preparation，并在返回 writable handle 前等待 publication。 + +### Prepared generation API + +```text +interface PreparedJsonlMigration { + readonly sourceIdentity: JsonlPhysicalIdentity + readonly artifact: SessionFormatArtifact + publish(): Promise +} +``` + +`prepareJsonlMigration()` 读取一个稳定 historical revision，只执行一次完整 Stage chain，并在不 encode、不写文件的情况下返回 current artifact。`publish()` 是幂等操作：并发与后续调用共享同一个终态 Promise（包括拒绝结果），不会对同一 prepared artifact 重复 encode。 + +`publish()` 把 current records 流式写入同目录排他创建的 temporary file，执行 sync，等待 bounded Worker verifier，比较 preparation 捕获的 source identity，再通过 no-overwrite 操作发布 canonical path。成功 publisher 复用 prepared logical artifact，不重新 Decode 自己的 target。竞争失败者只验证 winner 以精确 staged migration prefix 开头；append tail validation 仍属于 current reader。 + +Publication 调用后会运行到 settlement，不会被 write caller 中途取消。Write open 会在 publication 前后检查 caller signal，因此取消可能在后继已经提交后拒绝 open，但不会泄漏 write lease。Source identity 变化会抛出 `JsonlGenerationSourceChangedError`、删除临时文件，并且不会重复 Decode 或 migration。 + +### Preparation ownership 与取消 + +Persistence backend 按 Session id、selected source path 与 stat-derived revision 保存一个 in-flight entry： + +```text +interface MigrationPreparation { + sourcePath: string + sourceRevision: SessionPersistenceRevision + controller: AbortController + promise: Promise + settled: boolean + waiters: number +} +``` + +新的 read/write open 只有在 source path 与 revision 仍匹配时才加入已有 entry。`waitWithAbort()` 让每个 caller 的 AbortSignal 与 shared Promise 竞争，但不会把 caller signal 传给共享工作。只有最后一个 waiter 在 preparation 仍运行时离开，backend-owned controller 才会 abort。取消测试暂停物理读取，并在取消一个 caller 前观察到两个已注册的 waiter；仅让出一次事件循环不能证明异步路径与 revision 查找后的加入已经完成。 + +完成结果进入既有 bounded `coldLogMemo`。`StoredLog` 判别字段把已发布 current state 与 `PreparedStoredLog` 分开，后者的 `publication` 字段把 current logical events 与匹配的 publication operation 绑定，使 query 后紧接的 Agent resume 复用同一次 Decode 与 migration。In-flight map 只拥有运行中的工作，不是第二个 completed-result cache。 + +`SessionHandle.read()` 会报告 event value 是 detached 还是 shared-frozen。JSONL backend 在 memo 化前只对每个已解码 event graph 深度冻结一次，并在该处构造 `shared-frozen` 结果；后续读取和 slice 即使为空也会保留生产者建立的状态。`readColdSessionLog()` 将这些 event 与本地独占的 interrupted-turn closer 组合，并通过 `SessionObservationReader` 继续传递 `eventState`；`Session.fromRestore()` 只校验和接管 seed，不再复制或冻结。普通 create 与 fork seed 继续使用 defensive snapshot 路径。 + +Read-only restoration 会校验 Session runtime 直接依赖的 event 与 settlement 字段，但不会展开每一段嵌入式 Assistant stream。Publication Worker 继续执行完整 stream replay，并在提交 migrated successor 前校验 content、usage 与 replay state 一致性。已有 current-v2 文件信任其 writer；需要展开 compact stream 的 consumer 会在读取时校验 record。 + +### Read handle 切换 + +Current generation 不存在时，read open 会采用在 `state.primed` 中保存 prepared events 的 handle。后续每次 `read()` 都重新解析 current path： + +```text +if current generation is absent: + return slice of primed events +else: + clear primed events + read current generation and enforce non-shrinking history +``` + +因此，一个已有 historical Session 也可能让 `resolveCurrentLog()` 返回 `undefined`：它回答的是 current canonical file 是否存在，而不是 Session 是否可读。公开 `stat` 与 `list` 继续发现 historical header。 + +### Write-open publication + +Write open 先取得进程内 claim 与内核支持的跨进程 lease，再重新解析 selected generation。如果它仍是 historical，就取得或复用 prepared `StoredLog` 并等待 `publish()`。之后才返回以 prepared events 为 primed state 的 write handle。 + +```text +write open + → claim process-local ownership + → acquire SessionWriteLease + → re-resolve generation + → join or create preparation + → encode + sync temp + → Worker verify + → source identity check + → no-overwrite publish + → return writable handle +``` + +Handle 返回前，外部 caller 无法 append。因此 `append`、`flush` 与 `close` 保持普通 current-generation 行为，不需要“publishing”分支。Service `flush()` 继续只 flush 已经 adopt 的 writer；它不会把 read-only preparation 转成 write。 + +### Follow 与 Agent promotion + +`session.follow` 通过 read path 打开历史、恢复 Session 与 projections、发出 opening snapshot，然后启动 Agent promotion。Agent resume 使用 write open，因此会在 Agent 接收新一轮对话前等待 publication。历史可见与写入就绪成为两个明确时间点，同时不引入 unpublished append state。 + +## 问题与方案对照 + +| 串行流程问题 | 实现机制 |

No second source read occurs. + +The artifact belongs to the target session receiving the context. Its descriptive source is `{ kind: "session-reference", sessionId, label }`, where `sessionId` identifies the referenced session.

It carries the saved locator and backend `retrievalHint`, or an unavailable outcome distinguishing missing storage from a failed save. This notice is model-visible content in the same durable reference message, not metadata-only UI decoration. A tiny preview budget cannot remove it. The saved transcript carries capture metadata, including `capturedFormatVersion`, and the same untrusted-background warning as the preview. Per-message JSON string fragments contain at most 64 Unicode code points per line; decoding and concatenating them restores exact text, including original newlines. This fixed artifact format keeps long single-line middles retrievable with ordinary paged file reads without changing preview retention. + +Cancellation after an asynchronous save prevents context publication, even if storage already created the artifact.

Notices add request tokens outside that budget, and retrieval adds the requested transcript text later.

Top-level teardown is host-owned rather than represented as another Activation. Manager unload invokes its internal manager-wide drain to close admission synchronously, await every admitted materialization through publication or rollback, stop the stable live forest, and release it child-first. A host that owns selected top-level Agents uses `drainContinuableDescendants(parents)`: exact Agent identities close admission only below those roots until each leaves the registry, while unrelated forests and manager-wide admission remain live; the manager stops their visible descendants before its first await, waits only materializations admitted below those roots, and releases only the selected branches. Every materialized start and live delivery rechecks caller cancellation, the applicable draining scope, Activation disposal, and exact parent authority in the same synchronous span as inbox submission, so teardown or parent replacement that wins before acceptance prevents delivery to the closing handle.

Each Activation installs one memoized disposal promise before cancellation or recursive callbacks, allowing scoped host shutdown, global manager unload, child release, and normal settlement to converge without double release. Cancellation propagates top-down before slow descendant cleanup; handle release remains child-first.

It shipped as hand-authored `lib/` JavaScript installed through `dsh plugin add`: untyped, untested, calling `node:child_process` directly, hand-rolling its own dropdown and style tag, carrying a browser-side DSH-version gate against rc6–rc8, and probing `process.argv` to guess the running dsh version. Users wanted the feature as a shipped part of the Web profile, which the bundle-install path cannot give it — and the external form violates nearly every repository convention (locale-owned copy, per-file coverage, wire-boundary validation, capability seams for host commands). + +## Decision + +The first-party feature is named `open-in-app`: it selects the application that opens a workspace directory on the Harness host, not another machine or destination. + +The feature's first-party owners are `@deepseek-ai/dsh-host-open-in-app` at `packages/host/open-in-app/` (the probe, catalog, and launch routes) and `@deepseek-ai/dsh-client-ui-open-in-app` at `packages/client/ui-open-in-app/` (the split button), mounted in the Web profile by the `dsh-web-app` bundle rows `open-in-app` and `ui-open-in-app`. The promotion is a rewrite, not a vendoring: + +- **A host/client package pair, following the `directory-picker-browse`/`ui-directory-picker-browse` pairing**: the host package's `src/index.ts` registers the three HTTP routes on `ctx.webServer` (`GET /open-in-app/apps`, `GET /open-in-app/icon/`, `POST /open-in-app/open`); the ui package's `src/client/index.ts` registers the split button into `conversation.session.header.utilities` through the standard slot/inject currency, with copy in a typed `open-in-app` locale namespace and styling in CSS Modules over `--dsw-*` tokens (the original's hand-injected style tag and inline dropdown are replaced by the `Menu` primitive), over an empty-apply node half that keeps the plugin on the host roster. Route paths and wire payload types have one home, the host package's browser-safe `./shared` subpath (constants and types only); the client bundle inlines it through an `INLINE_SAFE` entry in the client tsdown preset, the same channel `dsh-session`'s wire slices use. The host root exports only the Loader-required plugin values and types; catalog, resolver, launcher, and icon helpers remain source-internal. +- **One resolution pass yields verified launchers; a click never re-detects.** The host resolves the whole catalog lazily once per process into a map of catalog id to `OpenInAppResolvedLaunch` — a launcher this host actually holds, never a bare install record. `GET /apps` serves the map's keys and `POST /open` launches its value directly; a launch whose executable is gone (spawn `ENOENT`) invalidates that one entry, re-resolves it once, and drops it from the list when nothing proves it anymore (so uninstalls self-heal while new installs wait for a restart). +- **Resolution sources are platform-honest and cheap.** macOS checks the known application directories (`/Applications`, `~/Applications`) for the entry's bundle spellings and launches `open -a `; Xcode follows `xcode-select -p`. Windows reads `App Paths`, then Uninstall records kept only when they prove an executable on disk, then known paths and the newest versioned install directory where an application uses one — one batched `reg.exe query` per root per pass. GitHub Desktop resolves its versioned executable together with the packaged `cli.js` and invokes the supported `github open ` behavior without a command shell. CLI names resolve in-process through `ctx.subprocess.resolveExecutable()` (PATH/PATHEXT stat, no shell, no `which`/`where.exe` children); Linux GUI entries whose CLI is off PATH fall back to their XDG desktop entry's verified `TryExec`/`Exec`, while `xdg-open` is offered only when the host announces a display server. The remaining host commands (`xcode-select`, `reg.exe`, icon extraction) run through `@deepseek-ai/dsh-native-command` (argv, never a shell). +- **Three independent deadlines replace the single `commandTimeoutMs`**: `probeTimeoutMs` (resolution commands), `iconTimeoutMs` (icon extraction commands), and `launchWatchMs` (the early-failure watch window), so tuning one operation never changes another's response time — the shipped bundle keeps conservative 10 s command deadlines (timeouts are failure bounds, not latency budgets) with a 1 s watch window, which is what bounds how long the open route and the button's busy dress hold a successful launch. Launches spawn detached with a credential-scrubbed environment (`scrubbedParentEnv` from `dsh-subprocess`) plus explicit adapter entries; Windows GUI launchers remain visible unless an adapter explicitly hides its CLI process because that process opens the GUI separately. A launcher still running when the watch window closes counts as launched and is never killed or awaited (kitty and the JetBrains IDEs stay in the foreground for their window lifetime). +- **Icons extract on every platform with a host source.** macOS converts the resolved bundle's `.icns` to a 128px PNG (`plutil` + `sips`); Windows extracts the resolved executable's associated icon as a 32px PNG through a generated PowerShell script run with positional `-File` args (no command-line path parsing); Linux follows the spec's desktop entry `Icon=` into the hicolor theme and pixmaps directories (PNG or SVG, filesystem only). Any failure answers 404 and the browser keeps its generic glyph. +- **The launch catalog is a data table with per-platform entries** (`OPEN_IN_APP_CATALOG`): each application id declares, per platform (`darwin`/`win32`/`linux`), a chain of launcher sources tried in order — `fixed` (ships with the OS), `app` (known-directory bundle spellings), `xcode` (`xcode-select -p`), `cli` (in-process PATH resolution), `file` (first existing candidate under `${VAR}`/`~/` expansion), `scan` (newest versioned install directory), `app-paths` and `install-record` (the Windows registry tiers), `github-desktop` (the versioned executable plus packaged CLI), and `desktop` (Linux XDG desktop entries) — plus a launcher argv template (a `{path}` token carries the directory in place, otherwise it is appended), optional environment and Windows visibility policy, and an optional fallback launcher (Xcode's `open -a ` behind `xed`). The whitelist follows Codex's "Open In" target list: editors and IDEs (VS Code, VS Code Insiders, Cursor, Windsurf, Zed, Sublime Text, Xcode, Android Studio, seven JetBrains IDEs), the promoted plugin's Git GUIs, terminals (Terminal, iTerm2, Ghostty, Warp, kitty, Windows Terminal, Git Bash, GNOME Terminal, Konsole), and per-platform file managers. File managers and platform terminals are separate ids (`finder`/`explorer`/`filemanager`) rather than one id with per-platform labels, because labels are static browser dictionary entries and only one of them probes as available per host. The file-manager entries launch through `dsh-native-command`'s path opener itself (`shell-open`, the OS shell's open verb with the full parent environment, not a detached scrubbed spawn), because a direct `explorer.exe ` spawn does not reliably raise a window. Closed unions end in `assertNever`. +- **Every route runs behind the composition connection service's trust fence** (`requestRejection`: the Host/Origin fence defeating DNS rebinding and cross-site calls, plus browser authentication), the same guard the API gateway applies to its WebSocket upgrade; the mechanism's one home is the `src/index.ts` module comment. On top of that fence the open route validates the body at the wire: an `application/json` media type (exact essence, not a substring match), a 64 KiB bound with a drained 413, string field types, only probed-available catalog ids, and an absolute path naming an existing directory. +- **The DSH-version gate is deleted.** It existed because the plugin rode release-to-release against an interface it did not own; a first-party package is versioned with the repository, so the gate, its `sessionStorage`/`localStorage` trust ledger, and the argv-walking version probe have no referent. +- **The last choice persists through `createSnapshotStore(..., { persist })`** (`dsh.open-in-app.choice`), replacing hand-rolled `localStorage` access. A fresh store has no platform-specific choice; the component uses the first available host entry until the user chooses one. + +The pair lives in `packages/host/` and `packages/client/` because that is what the halves are: the probe/launch side is host infrastructure beside the webserver it consumes, and the button is a client surface beside the other `ui-*` packages. Review moved it there from a single dual-half package in `packages/workspace/` (see Alternatives). + +## Alternatives considered + +**Vendor the plugin's `lib/` as-is under `packages/`.** Fastest, but the hand-authored JavaScript fails typecheck, coverage, i18n, JSDoc, and invariant gates wholesale; keeping it exempt would create a package class the repository deliberately does not have. + +**A Typert Remote instead of raw webServer routes.** The apps/open calls fit the Remote RPC shape, but the icon route serves binary PNGs, which the JSON RPC vocabulary does not carry; splitting icons onto a raw route while apps/open ride Remote gives two transports for one feature. Raw routes also match the original's client, and `webhook-github` establishes the validated-raw-route pattern. + +**Extend `host/apiproxy`'s `openPath` instead of a new open endpoint.** `openPath` opens one path with the OS-default application; this feature's subject is *which* application, with availability probing and per-application launchers — a different contract. Both share `dsh-native-command`. + +**One dual-half package in `packages/workspace/` (the shape that shipped first, following `dsh-session-log-export`).** Split during review into the host/client pair: the workspace group's contract is host-side only, the feature consumes `webServer` rather than `workspaceRegistry`, and registering the single package on the Client compiler aggregate forced the host route and catalog tests to pose as `.client.spec.ts`. The split puts each half's tests on its own compiler face and its dependencies in the right sections; the wire contract stayed in one home via the host package's `./shared` subpath. + +**A configurable catalog (cordis.yml-defined applications).** Deferred: each entry couples discovery, launch arguments, process policy, and icon behavior, so a user-facing settings owner and validation rules are required before accepting arbitrary commands. User-supplied labels are user data and do not conflict with locale-owned product copy. Codex and Orca demonstrate the likely extension: maintained built-in presets plus configurable custom handlers. + +**Enumerating every installed application through operating-system APIs.** Rejected as the menu's authority: Launch Services, Windows registration data, and XDG desktop entries can locate applications, but they do not establish which applications accept a workspace directory or which launch protocol opens it correctly. OS-native identifiers remain useful locator inputs for maintained presets; custom handlers cover the long tail without guessing launch semantics. + +**Shipping static icons for Windows/Linux entries (Codex bundles PNGs per target).** Rejected: the icon route serves real host icons on all three platforms, and bundling third-party product artwork adds an asset pipeline and trademark surface for cosmetic gain. + +**Subprocess-heavy detection (the shape that shipped first): `open -Ra` per macOS entry, `which`/`where.exe` per CLI, and a re-resolution on every launch.** Replaced during review: a list resolution spawned ~26 children on macOS, display-name Launch Services queries are weaker evidence than an on-disk bundle, the repository already carries in-process PATH resolution (`ctx.subprocess.resolveExecutable()`), and re-detecting on click put the probe deadline on the interactive path. A batched-`mdfind` fallback for relocated macOS bundles was also considered and left out with the review's known-paths instruction; the miss is recorded as a Known Limitation. A native LaunchServices/NSWorkspace lookup would need an addon the repository does not carry — deferred, with known `.app` paths as the stand-in. + +**A public application-discovery Service Definition.** Deferred on the single-consumer rule: the resolver stays a package-internal module until a second GUI discovery consumer exists. + +**128px Windows icons through an `SHDefExtractIcon` P/Invoke (`Add-Type`) script.** Deferred: `ExtractAssociatedIcon` is the stock .NET surface with no compiled snippet, and 32px only softens slightly at the button's 15-18 CSS px on high-DPI displays; the P/Invoke variant is a script-local upgrade if that softness matters in practice. Following the user's active Linux icon theme was likewise left out — hicolor is the freedesktop fallback every theme inherits from — so themed desktops may see the stock icon. + +## Consequences + +- The Web profile gains the header button wherever the host probes at least one installed catalog application on macOS, Windows, or Linux, with zero rendering elsewhere (empty probed catalog → the component returns null). +- The community plugin's install path remains valid but redundant; its original routes and browser choice key are separate from `open-in-app`, so installations using the first-party feature should remove the community plugin to avoid duplicate header controls. +- Resolution and icons run lazily, once per host process, so an application installed while dsh runs appears only after restart — accepted; the uninstall direction self-heals through the `ENOENT` single-entry refresh. +- The catalog is compile-time fixed; extending it means editing `OPEN_IN_APP_CATALOG` and both locale dictionaries together (README Known Limitations). Platform coverage is uneven — several Git GUIs and terminals are macOS-only entries, Windows icons are limited to the 32px stock .NET extraction, Linux follows hicolor rather than the active theme, and CLI-only entries without a desktop record keep the generic icon. +- Coverage: resolver logic (every locator kind over temp filesystems, registry-dump and desktop-entry fixtures, an injected env/home/PATH table), per-platform icon extraction, the three routes (real Loader + real WebServer composition, including the one-pass cache, the `ENOENT` refresh, and HMR-safety disposal), controller wire behavior, and component presentation are unit-tested to the per-file 100% gate; no snapshot is added because the shipped keyless snapshot fixtures assert session-driven output, which this browser-side control never touches. The web ARIA goldens disable the `open-in-app` and `ui-open-in-app` rows, and the Host-only preset e2e composition disables the host row: the button reflects whatever applications the running machine has installed, so its presence and label are host facts no cross-platform golden can pin. diff --git a/.agents/notes/implemented/feature/2026-08-25-promote-open-anywhere-plugin.zh.md

`conversation.session.header.utilities`，文案在类型化的 `open-in-app` locale 命名空间中，样式为 `--dsw-*` token 上的 CSS Modules（原插件手工注入的 style 标签与内联下拉被 `Menu` 原语替代），节点半边是让插件出现在主机名册上的空 apply。路由路径与 wire 载荷类型只有一个家：host 包浏览器安全的 `./shared` 子路径（只有常量与类型）；client bundle 经 client tsdown preset 的 `INLINE_SAFE` 条目将其内联，与 `dsh-session` 各 wire 切片同一通道。host 根入口只导出 Loader 所需的插件实体与类型；目录、resolver、launcher 与图标 helper 保持源码内部可见。 +- **一趟解析产出已验证的启动器；点击绝不重新检测。** 主机把整个目录每进程惰性解析一次，产出目录 id 到 `OpenInAppResolvedLaunch` 的映射——本机实际持有的启动器，绝不是裸的安装记录。`GET /apps` 提供映射的 keys，`POST /open` 直接启动其值；启动时发现可执行文件已消失（spawn `ENOENT`）会只作废该条目、重解析一次，无法再证明时把它从列表移除（卸载自愈，新安装等重启）。 +- **解析来源按平台务实且廉价。** macOS 在已知应用目录（`/Applications`、`~/Applications`）查条目的 bundle 拼写，启动 `open -a <解析出的 bundle>`；Xcode 跟随 `xcode-select -p`。Windows 依次读 `App Paths`、只在能证明磁盘可执行文件时采用的 Uninstall 记录、已知路径，以及采用版本化安装目录的应用中最新的目录——每趟每根一条批量 `reg.exe query`。GitHub Desktop 会同时解析版本化可执行文件与随包提供的 `cli.js`，不经命令 shell 调用受支持的 `github open ` 行为。CLI 名称经 `ctx.subprocess.resolveExecutable()` 进程内解析（PATH/PATHEXT stat，无 shell、无 `which`/`where.exe` 子进程）；CLI 不在 PATH 上的 Linux GUI 条目回退到其 XDG desktop 条目验证过的 `TryExec`/`Exec`，且只有主机声明了 display server 时才提供 `xdg-open`。其余主机命令（`xcode-select`、`reg.exe`、图标提取）经 `@deepseek-ai/dsh-native-command`（argv，绝不走 shell）执行。 +- **三个独立期限取代单一 `commandTimeoutMs`**：`probeTimeoutMs`（解析命令）、`iconTimeoutMs`（图标提取命令）、`launchWatchMs`（早期失败看护窗口），调整一种操作的超时不再改变其他操作的响应时间——随发行 bundle 保守地保留 10 秒命令期限（超时是失败上界而非延迟预算），看护窗口 1 秒，它才是约束 open 路由与按钮忙碌态挂起一次成功启动时长的量。启动以清理过凭据的环境（`dsh-subprocess` 的 `scrubbedParentEnv`）叠加适配器显式环境后 detached 派生；Windows GUI launcher 默认保持可见，只有负责另行打开 GUI 的 CLI 适配器会显式隐藏自己的进程。看护窗口关闭时仍在运行的启动器计为已启动，绝不会被杀死或等待（kitty 与 JetBrains IDE 在整个窗口生命周期内保持前台）。 +- **有主机来源的平台都提取图标。** macOS 把解析出的 bundle 的 `.icns` 转 128px PNG（`plutil` + `sips`）；Windows 用生成的 PowerShell 脚本以位置式 `-File` 参数（路径不经命令行解析）提取解析出的可执行文件的关联图标为 32px PNG；Linux 沿 spec 的 desktop 条目 `Icon=` 查 hicolor 主题与 pixmaps 目录（PNG 或 SVG，纯文件系统）。任何失败应答 404，浏览器保持通用占位图形。 +- **启动目录是按平台声明条目的数据表**（`OPEN_IN_APP_CATALOG`）：每个应用 id 按平台（`darwin`/`win32`/`linux`）声明一条按序尝试的启动器来源链——`fixed`（随系统内置）、`app`（已知目录的 bundle 拼写）、`xcode`（`xcode-select -p`）、`cli`（进程内 PATH 解析）、`file`（`${VAR}`/`~/` 展开后第一个存在的候选文件）、`scan`（带版本号安装目录取最新）、`app-paths` 与 `install-record`（Windows 注册表两层）、`github-desktop`（版本化可执行文件与随包 CLI）、`desktop`（Linux XDG desktop 条目）——加启动器 argv 模板（`{path}` token 原位携带目录，否则目录追加在末尾）、可选环境与 Windows 可见性策略，以及可选回退启动器（`xed` 之后的 `open -a `）。白名单对齐 Codex 的 "Open In" 目标列表：编辑器与 IDE（VS Code、VS Code Insiders、Cursor、Windsurf、Zed、Sublime Text、Xcode、Android Studio、七个 JetBrains IDE）、转正插件原有的 Git GUI、终端（Terminal、iTerm2、Ghostty、Warp、kitty、Windows Terminal、Git Bash、GNOME Terminal、Konsole）与各平台文件管理器。文件管理器与平台终端使用独立 id（`finder`/`explorer`/`filemanager`），而非一个 id 配平台标签，因为标签是静态浏览器词典条目，且每台主机只会探测到其中一个。文件管理器条目直接经 `dsh-native-command` 的路径打开器启动（`shell-open`，OS shell 的 open verb，携带完整父环境，而非 detached 的清理环境 spawn），因为直接 spawn `explorer.exe ` 不能可靠地弹出窗口。封闭 union 以 `assertNever` 收尾。 +- **所有路由都运行在组合 connection 服务的信任栅栏之后**（`requestRejection`：挫败 DNS rebinding 与跨站调用的 Host/Origin 栅栏，加上浏览器认证），与 API gateway 施加在其 WebSocket upgrade 上的守卫相同；机制的唯一出处是 `src/index.ts` 的模块注释。在该栅栏之上，open 路由在 wire 边界校验请求体：`application/json` 媒体类型（精确 essence，而非子串匹配）、以排空后 413 的方式把 body 限制在 64 KiB、校验字段类型、只接受探测为可用的目录 id，并要求指向现存目录的绝对路径。 +- **删除了 DSH 版本门禁。** 它存在是因为插件逐版本骑乘一个它不拥有的接口；第一方包与仓库同版本发布，门禁、它的 `sessionStorage`/`localStorage` 信任台账和 argv 遍历版本探测都失去了所指。 +- **上次选择经 `createSnapshotStore(..., { persist })` 持久化**（`dsh.open-in-app.choice`），替代手写 `localStorage` 访问。新存储没有平台特定的初始选择；用户首次选择前，组件使用主机提供的第一个可用条目。 + +这对包放在 `packages/host/` 与 `packages/client/`，因为两个半边本来就是这两种东西：探测/启动侧是主机基础设施，与它消费的 webserver 同组；按钮是客户端表面，与其他 `ui-*` 包同组。评审把它从 `packages/workspace/` 的单个双半边包迁到这里（见替代方案）。 + +## 考虑过的替代方案 + +**将插件的 `lib/` 原样 vendor 进 `packages/`。** 最快，但手写 JavaScript 会整体不过 typecheck、覆盖率、i18n、JSDoc 和 invariant 门禁；为其保留豁免会造出仓库刻意不设的包类别。 + +**用 Typert Remote 而非裸 webServer 路由。** apps/open 调用符合 Remote RPC 形态，但 icon 路由提供二进制 PNG，JSON RPC 词汇承载不了；把 icon 拆去裸路由而 apps/open 走 Remote 会让一个功能有两种传输。裸路由也匹配原插件的客户端，且 `webhook-github` 已确立带校验裸路由的先例。 + +**扩展 `host/apiproxy` 的 `openPath` 而非新 open 端点。** `openPath` 用系统默认应用打开一个路径；本功能的主体是*用哪个*应用，带可用性探测和逐应用启动器——是不同的契约。两者共享 `dsh-native-command`。 + +**放在 `packages/workspace/` 的单个双半边包（最初交付的形态，沿用 `dsh-session-log-export`）。** 评审期拆成 host/client 对：workspace 组的契约是 host-side only，该功能消费的是 `webServer` 而非 `workspaceRegistry`，且单包整体注册在 Client 编译聚合面迫使主机路由与目录测试伪装成 `.client.spec.ts`。拆分让每个半边的测试落在自己的编译面、依赖落在正确的区段；wire 契约经 host 包的 `./shared` 子路径保持唯一出处。 + +**可配置目录（cordis.yml 定义应用）。** 延后：每个条目耦合发现、启动参数、进程策略与图标行为，因此接受任意命令前需要明确的用户设置归属与校验规则。用户提供的 label 属于用户数据，不与 locale 拥有的产品文案冲突。Codex 与 Orca 展示了可能的扩展形态：维护过的内置 preset 加可配置 custom handler。 + +**通过操作系统 API 枚举所有已安装应用。** 不作为菜单真源：Launch Services、Windows 注册信息与 XDG desktop 条目可以定位应用，但不能证明每个应用都能接收 workspace 目录，也不能给出正确打开目录所需的启动协议。OS 原生标识仍可作为维护过的 preset 的 locator 输入；custom handler 用于覆盖长尾，而不是猜测启动语义。 + +**为 Windows/Linux 条目内置静态图标（Codex 为每个目标打包 PNG）。** 拒绝：图标路由在三个平台都提供主机真实图标，为装饰性收益打包第三方产品图形会引入资产管线与商标风险面。 + +**重子进程检测（最初交付的形态）：macOS 每条目一次 `open -Ra`、CLI 各一次 `which`/`where.exe`、每次启动重新解析。** 评审期替换：一次列表解析在 macOS 上派生约 26 个子进程，按显示名查 Launch Services 的证据弱于磁盘上的 bundle，仓库已有进程内 PATH 解析（`ctx.subprocess.resolveExecutable()`），且点击时重新检测把探测期限放上了交互路径。为挪位 macOS bundle 考虑过批量 `mdfind` 兜底，依评审的 known-paths 指示未采用；漏检记入已知限制。原生 LaunchServices/NSWorkspace 查询需要仓库尚无的 addon——延后，以已知 `.app` 路径为替身。 + +**公共的应用发现 Service Definition。** 按单消费者规则延后：在出现第二个 GUI 发现消费者之前，resolver 保持为包内模块。 + +**经 `SHDefExtractIcon` P/Invoke（`Add-Type`）脚本取 128px Windows 图标。** 延后：`ExtractAssociatedIcon` 是不需编译片段的 .NET 标准面，32px 在按钮 15-18 CSS px 的尺寸上仅在高分屏略微发软；若实际在意，P/Invoke 变体是脚本内局部升级。同理未追用户的 Linux 图标主题——hicolor 是所有主题继承的 freedesktop 兜底——自定义主题桌面会看到原版图标。 + +## 后果 + +- 只要主机在 macOS、Windows 或 Linux 上探测到至少一个已安装的目录应用，Web profile 就会出现头部按钮；其余情况零渲染（探测目录为空 → 组件返回 null）。 +- 社区插件的安装路径仍然有效但已冗余；其原始路由与浏览器选择键独立于 `open-in-app`，因此使用第一方功能的安装应移除社区插件，避免出现重复的头部控件。 +- 解析与图标每主机进程惰性执行一次，dsh 运行期间安装的应用要重启后才出现——接受；卸载方向经 `ENOENT` 单条目刷新自愈。 +- 目录在编译期固定；扩展它意味着同时编辑 `OPEN_IN_APP_CATALOG` 与两份 locale 词典（README 已知限制）。平台覆盖不均——若干 Git GUI 与终端仅有 macOS 条目；Windows 图标受限于 .NET 标准接口的 32px 提取，Linux 跟随 hicolor 而非当前主题，没有 desktop 记录的纯 CLI 条目则保留通用图标。 +- 覆盖：resolver 逻辑（每种 locator 在临时文件系统上、注册表转储与 desktop 条目 fixture、注入的 env/home/PATH 表）、逐平台图标提取、三条路由（真实 Loader + 真实 WebServer 组合，含单趟缓存、`ENOENT` 刷新与 HMR 安全处置）、controller wire 行为和组件呈现都以逐文件 100% 门禁做了单元测试；不新增 snapshot，因为随仓库发布的免密 snapshot fixture 断言会话驱动的输出，而这个纯浏览器侧控件不触及它。Web ARIA golden 禁用 `open-in-app` 与 `ui-open-in-app` 两行，Host-only 的 preset e2e 组合禁用 host 行：按钮反映运行机器实际安装了哪些应用，其出现与否和标签都是主机事实，跨平台 golden 无法钉住。 diff --git a/.agents/notes/implemented/feature/2026-08-27-continuable-subagent-human-inbox-control.i18n.yaml

The Client discarded its existing Queue/Steer choice when it selected the dedicated subagent prompt Remote, and the generic Session ownership fence rejected every queue mutation for a subagent-owned identity. The browser therefore hid controls that the live child inbox already supported. + +Opening generic Session control indiscriminately would weaken the subagent ownership rule. Prompt delivery still needs exact live direct-parent authorization and cold-resume accounting, while queue mutation must reject one-shot, unknown, corrupt, and cold children. A valid continuable descriptor in the child's own log suffix identifies which live subagent-owned Sessions may use occurrence mutation. Settlement must also retain an idle Agent while a delivery a driver will claim is still pending, and must not tear down an Agent that claimed the idle phase for a maintenance task after `whenIdle()` resolved. + +## Decision + +A live continuable child exposes the ordinary human inbox controls without adding another queue, Remote endpoint, queue action, or Host-facing subagent operation. One-shot children remain read-only. + +The existing `SubagentPromptRequest` carries `delivery: 'queue' | 'steer'`. The Client forwards the mode already selected by `Session.prompt(content, mode)` through `subagent.prompt`. The Remote still requires the exact live direct parent and then uses one package-internal continuation-manager delivery operation. Queue calls `Agent.followup(message)`; steer calls `Agent.steer(message)`. Both paths share child locking, cold resume, final parent reauthorization, caller-signal cutoff, `MessageId` creation, rollback, and disposal-race handling. This human choice adds no public scheduling method or model tool; the separately owned `sendMessage()` and model-facing `send_message` operation keep their fixed adjacent-Agent Steer semantics. + +The browser gives a continuable child the ordinary busy Enter/Cmd+Enter Queue/Steer preference, QueueDock Edit/Remove/Steer actions, and empty-draft steer-all gesture. Send and Stop remain independent controls. Composer prompts still require the live parent because their Remote mints new admitted work. QueueDock mutations address already-live inbox work directly, so they remain available when the parent is offline; the parent-offline composer stays locked. + +The existing `session.updateQueue(itemId, action)` resolves the exact live Agent and admits a subagent-owned Session only when its current projected identity is continuable and the descriptor sequence belongs to the child's own non-seed suffix. A live one-shot Agent and a missing, inherited-only, or invalid identity retain the ownership failure. An absent Agent returns `queue-item-not-found` and does not cold-resume the child. The target Session id is sufficient human authority for a live inbox occurrence mutation; a parent address is not required. Edit and Remove retain their complete existing `nextTurn` and `nextStep` semantics, including plugin-injected context, while Steer requires a queued occurrence and an Agent that reports running when the command begins. + +The continuation manager keeps no second message-reservation state. One private `SubagentInbox` delegates Queue and Steer to the Agent inbox and owns the Activation's existing closing promise. Natural settlement waits for `Agent.whenIdle()`, an empty child Inbox, and disposal of every owned child. The manager confirms the Inbox, owned-child set, and wake generation under the child lock, then flushes final Session state while admission remains open. The final child-lock decision revalidates the Session sequence and the same residency facts, then synchronously starts an `Agent.runMaintenance()` task whose entry claims the idle phase and closes the wrapper in the same JavaScript turn. Every pending Inbox occurrence retains the Activation regardless of its delivery mode or provenance. Manager-owned deliveries, Inbox claims or discards, and owned-child release renew the wake generation. Direct Agent work accepted during the flush either changes the final Session or residency observation, remains active and prevents the final maintenance task from starting, or completes before revalidation. + +QueueDock Steer uses the Agent's best-effort delivery after the command admits a running queued occurrence. If the queued occurrence was claimed first, `queue-item-not-found` leaves its ordinary Queue delivery underway. If active cancellation wins during the synchronous transfer, Agent steering appends the message to `nextTurn`, latches a wake, and the Session command still succeeds. The selected message moves behind the remaining Queue in that fallback case. Newly composed Steer uses the same fallback and remains deliverable when it misses the nearest step. + +This decision partially supersedes the human-control exclusions in [Web subagent catalog and human continuation](2026-07-27-web-subagent-conversations.md), [Continuable subagents](2026-07-28-continuable-subagent-conversations.md), [Steer a queued Web message](../../archived/feature/2026-07-30-web-queue-steer-action.md), and [Steer the whole Web queue with an empty-draft Cmd/Ctrl+Enter](../../archived/feature/2026-08-06-web-queue-steer-all-gesture.md). The active records own catalog authorization and Activation lifecycle; the archived records preserve the original QueueDock Steer and gesture decisions. + +## Alternatives considered + +**Add `SubagentRuntime.steer()` and a new Remote.** Rejected because human prompt delivery already has a mode-bearing Client method and one authenticated Remote. A new public operation would expand both the service and model-adjacent surface without adding an execution primitive. + +**Add `subagents.updateQueue`.** Rejected because `session.updateQueue` already owns exact inbox occurrence mutation and its race failures. The projected continuable identity provides the narrow ownership-fence exception without adding another operation. + +**Route every subagent control through generic Session APIs.** Rejected because prompt and cancellation require subagent lineage authorization, cold-resume accounting, and dedicated failure mapping. Only live inbox occurrence mutation has enough target-local state to use the narrow ownership-fence exception. + +**Restrict continuable queue mutation to `nextTurn`.** Rejected because human inbox parity intentionally includes editing or removing pending steering and injected context. If a plugin needs a stronger transaction around its `nextStep` input, that protection belongs to the shared Agent inbox semantics rather than a subagent-only restriction. + +**Track waking work by `MessageId` and transfer that record across mutation.** Rejected because it duplicates the Inbox's pending set with a second activity ledger and couples residency to occurrence identity. `whenIdle()` waits for existing Agent activity, `Inbox.hasPending` conservatively retains every occurrence, the Activation generation invalidates stale observations, and the final maintenance task atomically joins idle ownership to admission closure. This choice can retain quiet injected context, but it avoids both an additional mutation protocol and silent loss of accepted steering. + +**Derive residency from `MessageSource.kind`, treating `plugin` as parked context.** Rejected because `kind` records who produced a message, not how it was delivered, and `MessageSourceMap` is merge-extensible. Plugins steer with a plugin source (`cordis-host-runner` failure reports, blocking Stop hooks) and hosts inject with non-plugin sources (`dsh-experimental-agent-team` quiet mail), so the correspondence fails in both directions. Treating all pending occurrences alike avoids that unsupported inference. + +## Consequences + +Continuable child conversations and ordinary Sessions share one human inbox interaction model and one Agent-loop queue. Human steering can affect a resident or cold-resumed child without changing public model controls. QueueDock remains useful for a live child after its parent goes offline, while new messages continue to respect direct-parent authorization. + +The generic Session command has one narrow ownership-fence exception for a live subagent-owned Agent with a valid own-suffix continuable identity. Because the operation addresses either inbox destination, a caller that knows a pending `MessageId` can edit or remove plugin-supplied next-step input, exactly as on an ordinary Session. QueueDock renders only `queued`-placement rows, so no browser gesture reaches that input; an edit there also keeps the original producer's `MessageSource`, which would attribute human text to that producer. + +Inbox notifications retain their occurrence semantics and do not carry continuation residency. Claim and discard notifications only wake settlement after pending work changes; `whenIdle()`, the final idle-phase maintenance task, `Inbox.hasPending`, the owned-child set, the Activation generation, and the Session sequence decide whether disposal is safe without depending on scheduler ordering, message identity, or provenance. The final flush precedes the closing cutoff, so a detached hook, job completion, or direct Agent delivery accepted during that await invalidates the observation instead of being stopped by the resulting disposal. Maintenance that remains active prevents the final task from claiming the idle phase; maintenance that starts and finishes during the flush has completed before disposal. A child left holding only injected context remains resident even though no driver is obliged to claim it; without a later waking delivery, queue removal, or manager teardown, that child and its live ancestors can remain resident for the process lifetime. A replayed Inbox follows the same conservative rule without reconstructing how each pending message was delivered. + +Model-side scheduling remains fixed rather than caller-selectable. The adjacent-Agent `send_message` tool always uses Steer, while only the browser human path chooses Queue or Steer. diff --git

The [Node compatibility jobs](2026-09-06-node-compatibility-selfhosted.md) also follow the Linux switch with isolated setup; the verdict's `node-24-bench`, `python-sdk`, and `python-runtime` dependencies stay on standard hosted runners; in a broader GitHub-hosted capacity failure that also takes out the standard pools, those dependencies still block `all checks passed`. An outage therefore needs a switch any responder with repository write access can throw without merging anything. ## Decision -Each of the three required Linux worker jobs, the independent native Windows job, and the `all checks passed` verdict job — which would otherwise stay queued on the failed pool even after every worker passed — resolves its runner pool through a repository variable, and the switch is split by platform so an outage on one platform does not retarget the other. The three Linux workers and the `all checks passed` verdict (whose `needs` are the required Linux workers and which runs on the `vm-backup` pool) resolve through `DSH_CI_FAILOVER_LINUX`; the native Windows job resolves through `DSH_CI_FAILOVER_WINDOWS`. Unset (normal), they run on the hosted enterprise pools. Set to `selfhosted` by any repository writer, the corresponding jobs retarget onto the in-house self-hosted pool: under `DSH_CI_FAILOVER_LINUX`, the Linux jobs and verdict move onto the `vm-backup` pool, snapshot concurrency drops to the shared-VM bound, and the hosted-path pnpm cache restores are skipped; under `DSH_CI_FAILOVER_WINDOWS`, the native Windows job moves onto the `dsh-win-ci` pool. Each switch is writer-manageable repository state, not a merge, so it works while every check is red. The in-house pools' readiness is continuously re-proven by the `serial / linux (self-hosted standby)` and `serial / windows (self-hosted standby)` lanes, which run the complete unsharded aggregates on every master push. +The three primary Linux jobs (`node-24`, `node-24-coverage`, `node-24-consumers`), the three `node-compat` matrix entries, and `all-checks-passed` resolve through `DSH_CI_FAILOVER_LINUX`; the native Windows jobs resolve through `DSH_CI_FAILOVER_WINDOWS`. A platform switch does not redirect the other platform. Set to `selfhosted` by a repository writer, the applicable trusted jobs select `vm-backup` or `dsh-win-ci`; otherwise they retain their workflow-defined hosted fallbacks. Node compatibility jobs require a same-repository, non-fork head and a non-Dependabot author, use isolated runtime setup, and retain `ubuntu-latest` fallback. Linux failover bounds snapshot concurrency and skips hosted package-cache restores. The verdict follows its workers so it does not remain queued on an unavailable hosted pool. Each switch is writer-manageable repository state, not a merge, so it works while checks are red. The `serial / linux (self-hosted standby)` and `serial / windows (self-hosted standby)` lanes re-prove the complete unsharded aggregates on master pushes. `ci-master.yml` exempts exactly one event from `cancel-in-progress` (`${{ github.event_name != 'push' }}`), so one master push does not cancel the drill still running from the previous one. Each drill runs its complete unsharded aggregate with one gate worker, which takes longer than the interval between master merges; under unconditional cancellation a drill is superseded before reaching a verdict and the lane yields no readiness evidence for a responder to check. The exemption is narrower than "a drill always finishes", in two ways. GitHub keeps a single pending entry per group, so a newer pending run displaces an older one and intermediate push runs still end as `cancelled` during busy periods. And the expression is evaluated against the *newly triggered* run, so a run whose own event is not `push` — a benchmark dispatched on master within `ci-master.yml`, sharing its group `CI master-` — evaluates to `true` and does cancel a drill that is mid-flight. That is a rare manual action and the next master push restores the evidence, so it does not warrant further mechanism. What the carve-out buys is that the lane periodically reaches a verdict at all, which is what makes it usable as evidence. -The decision belongs at workflow level because cancellation applies to the whole superseded run: a job-level `concurrency` group does not exempt its job. The negated form is load-bearing rather than cosmetic: naming `pull_request` alone would also stop cancelling `workflow_dispatch`, and each runner benchmark fans out to twelve larger runners for up to fifteen minutes inside this same group on master, so a re-dispatch would queue ahead of a drill instead of replacing a stale measurement. What bounds the cost is that a master push in `ci-master.yml` carries only `wine-apt-cache` and these two drills; the pull-request jobs live in the separate `ci.yml` (which does not see `push`), and the benchmarks are `workflow_dispatch`-gated within `ci-master.yml`. `scripts/ci-workflow.spec.ts` pins that push-reachable set — classifying by exact condition, since a negated event test mentions the event it excludes — so a new push-reachable job cannot quietly start accumulating uncancelled runs. +The decision belongs at workflow level because cancellation applies to the whole superseded run: a job-level `concurrency` group does not exempt its job.

Their [release rehearsal decision](2026-09-06-release-rehearsal-selfhosted.md) owns the stricter event eligibility and hosted manual dispatch. This coupling is intentional: keeping the variable set to save release minutes also keeps the eligible main-CI Linux jobs self-hosted. Clearing it returns both workloads to their hosted targets for subsequent runs; publication stays hosted regardless. ### What the in-house pool is -`vm-backup`: one 64-core VM, six always-on systemd-managed runner instances.

In this repository's trust model that is not an escalation: the runner groups admit all workflows of this private, fork-disabled repository (a deliberate trade to make PR-ref failover possible at all), so any writer could already reach the VMs by pushing a branch workflow. The boundary against untrusted code is repository membership; the variables only route work for members. ## Capacity during failover -Six always-on instances absorb normal PR traffic (the pool's steady-state load is one serial standby job per master push, so failover capacity is effectively the full pool). If queues still build, register additional instances with an org registration token (org Settings → Actions → Runners → New runner). Clone an existing runner directory **excluding its identity files** — `rsync -a --exclude '.runner*' --exclude '.credentials*' --exclude '_diag' --exclude '_work' / /` (the globs also catch `.runner_migrated`/`.credentials_migrated`, which GitHub writes on migrated runners and which equally trigger the already-configured refusal) — then run `config.sh` (copying `.runner`/`.credentials` verbatim makes it refuse with "already configured"), and **start the listener**: `sudo ./svc.sh install ubuntu && sudo ./svc.sh start`. Registration alone leaves the runner offline; only a started service adds capacity. About a minute per instance. +Capacity includes the master standby, main-CI jobs, and three release-rehearsal jobs for each eligible PR or master push while the Linux switch is set. Each trusted PR also adds three Node compatibility jobs at gate concurrency one, including the build-backed Node 22 leg and cold temporary runtime downloads. The release workflows do not cancel running rehearsals when another run arrives, so overlapping refs can add sustained build, pack, and install load. Check current CPU, memory, disk, and queue pressure before extending self-hosted operation; extra registrations on this VM add scheduling slots, not machine resources. Do not infer spare capacity from the standby alone. When host resources permit extra registrations, use an org registration token (org Settings → Actions → Runners → New runner). Clone an existing runner directory **excluding its identity files** — `rsync -a --exclude '.runner*' --exclude '.credentials*' --exclude '_diag' --exclude '_work' / /` (the globs also catch `.runner_migrated`/`.credentials_migrated`, which GitHub writes on migrated runners and which equally trigger the already-configured refusal) — then run `config.sh` (copying `.runner`/`.credentials` verbatim makes it refuse with "already configured"), and **start the listener**: `sudo ./svc.sh install ubuntu && sudo ./svc.sh start`.

A repository variable is writer-manageable state that takes effect on re-run without a merge. -**Keep the self-hosted pool always in the required path.** Rejected because it trades hosted-pool availability for the in-house VM's, moving a single point of failure rather than adding a fallback.

Issue #3134's residue (`/tmp/dsh-*`) is one source; a second, larger source is the Node.js module compile cache. Tools in the CI toolchain call `module.enableCompileCache()` explicitly: pnpm 11.7.0 enables the cache in its entry (`module.enableCompileCache?.()` in `bin/pnpm.mjs`) on every invocation, and TypeScript does so in `tsc`/`tsserver`; vitest forwards the API but does not enable it itself. Every such call writes the serialized V8 bytecode cache under `os.tmpdir()/node-compile-cache`. On the shared VM that is the root partition's `/tmp`: measured 2026-08-28 at **697,389 inodes and 9.2 GB**, with 34,110 files younger than 1 hour — the cache grows on every CI run and is never cleaned, so the root partition's 3,276,800 inodes trend toward exhaustion even after the `dsh-*` residue is controlled. + +## Decision + +Each Linux lane that can run on the `vm-backup` pool under failover (`ci.yml` static/coverage/snapshots — hosted by default, self-hosted only when `DSH_CI_FAILOVER_LINUX=selfhosted` — and `ci-master.yml` serial standby, always self-hosted) redirects `NODE_COMPILE_CACHE` to the per-runner data-volume temp dir `${{ runner.temp }}/node-compile-cache`. `runner.temp` lives on `/data_local` (1 TB, ~1% inode used) and is per-runner (`_workNN/_temp`), so the cache stops consuming root-partition inodes. + +The redirect is a step right after `actions/checkout` that writes `NODE_COMPILE_CACHE=${{ runner.temp }}/node-compile-cache` into `$GITHUB_ENV`, so every later step in the lane — `pnpm/action-setup`, the store-path probe, install, Playwright install, and the test gate — inherits it. Injection is required because the `runner` context is unavailable in job-level `env` (the same constraint as the earlier TMPDIR work), and a step-level env on the gate step alone would leave the earlier pnpm calls writing to the root partition's `/tmp`. A confined child (bwrap/Landlock) whose sandbox does not grant the `runner.temp` path inherits the variable but **silently skips caching** — verified on the VM: with `NODE_COMPILE_CACHE` pointing at an ungranted path inside bwrap, `node` runs normally (exit 0), unlike `mkdtemp` which fails hard with a read-only filesystem error. The compile cache is best-effort by design; a failed write is a cache miss, not a crash. + +## Verification + +- VM probe: `NODE_COMPILE_CACHE=/data_local/ci/compile-cache-probe node -e 'require("node:fs")'` wrote a `v22.23.2-x64-*` cache subdirectory on the data disk (location switch effective). +- VM probe (bwrap): with `NODE_COMPILE_CACHE` set to a path the bwrap profile does not grant, `node` ran normally (exit 0) — cache write failure is tolerated. +- `scripts/ci-workflow.spec.ts` asserts every Linux lane injects `NODE_COMPILE_CACHE=${{ runner.temp }}/node-compile-cache` (a `$GITHUB_ENV` `KEY=VALUE` line) into `$GITHUB_ENV` before `pnpm/action-setup`; the position assertion fails if the injection moves after the first pnpm call. +- CI lanes: the three required Linux jobs (hosted by default, self-hosted `vm-backup` under `DSH_CI_FAILOVER_LINUX`) run the full suite under the new env; a regression in cache handling would surface as lane failure. + +## Alternatives considered + +### Why not disable the compile cache entirely? + +`NODE_DISABLE_COMPILE_CACHE=1` would stop root-partition growth immediately but forfeit the startup speedup on every run, and the cache is a legitimately useful Node feature (enabled explicitly by pnpm and TypeScript). Redirecting preserves the benefit while moving the cost off the constrained partition. + +### Why not add `node-compile-cache` to the `dsh-*` residue sweep? + +The CI sweep (added in the residue-cleanup change) targets test residue; the compile cache is a cache, not residue. Deleting it every run would discard the speedup the cache exists to provide. Redirecting is the structural fix: the cache's growth moves to the volume sized for it. + +### Why not job-level env or gate-step env only? + +The `runner` context is only available in step-level `env`; job-level `env` evaluates it to an empty string (GitHub contexts-availability), which would silently leave the cache on the root partition. A step-level env on the gate step alone would cover only that step: every earlier pnpm invocation in the lane (setup, store-path probe, install) would still write to the root partition's `/tmp`. Injecting into `$GITHUB_ENV` in a step between checkout and `pnpm/action-setup` sets the variable before the lane's first pnpm call, so one step covers the whole lane. + +## Consequences + +- **Bought**: the Node compile cache stops consuming root-partition inodes; inode pressure from this source is removed without losing the cache's startup benefit. The cache now lives in per-runner `_workNN/_temp` on the data volume. +- **Cost**: the cache accumulates in `runner.temp`, which the runner does not empty between jobs (measured earlier) — but on the data volume (~1% inode used) that is harmless. +- **Cost**: confined children without the `runner.temp` grant skip caching for their own `node` invocations; this is a cache miss, not a failure, and matches Node's best-effort contract. +- **Cost**: the change touches CI configuration only; local development keeps the default `os.tmpdir()` location. diff --git a/.agents/notes/implemented/process/2026-08-28-ci-node-compile-cache-data-disk.zh.md b/.agents/notes/implemented/process/2026-08-28-ci-node-compile-cache-data-disk.zh.md new file mode 100644 index 0000000000..c55a6c73cf --- /dev/null +++ b/.agents/notes/implemented/process/2026-08-28-ci-node-compile-cache-data-disk.zh.md @@ -0,0 +1,43 @@ +# Agent Note: 将 Node 编译缓存重定向到数据卷 runner 临时目录 + +Status: implemented + +[English](2026-08-28-ci-node-compile-cache-data-disk.md) | 中文 + +## 问题 + +自托管 Linux CI 虚拟机（`vm-backup` 池，32 个 runner 实例共宿一机）的根分区 inode 正在耗尽。issue #3134 的残留（`/tmp/dsh-*`）是来源之一；第二个、更大的来源是 Node.js 模块编译缓存。CI 工具链中的工具显式调用 `module.enableCompileCache()`：pnpm 11.7.0 在入口（`bin/pnpm.mjs` 中的 `module.enableCompileCache?.()`）每次调用都启用缓存，TypeScript 在 `tsc`/`tsserver` 中启用；vitest 转发该 API 但自身不启用。每次这样的调用都把序列化 V8 字节码缓存写到 `os.tmpdir()/node-compile-cache`。在共享虚拟机上即根分区的 `/tmp`：2026-08-28 实测为 **697,389 个 inode、9.2 GB**，其中 34,110 个文件不足 1 小时——缓存每次 CI 运行都在增长且从不清理，即使 `dsh-*` 残留被控制，根分区 3,276,800 个 inode 仍趋向耗尽。 + +## 决策 + +每个可能运行在 `vm-backup` 池的 Linux lane（`ci.yml` static/coverage/snapshots——默认 hosted，仅 `DSH_CI_FAILOVER_LINUX=selfhosted` 时自托管；`ci-master.yml` serial standby——始终自托管）都把 `NODE_COMPILE_CACHE` 重定向到 per-runner 数据卷临时目录 `${{ runner.temp }}/node-compile-cache`。`runner.temp` 在 `/data_local`（1 TB，inode 用量约 1%）上，per-runner（`_workNN/_temp`），因此缓存不再消耗根分区 inode。 + +重定向是在 `actions/checkout` 之后的一个 step，把 `NODE_COMPILE_CACHE=${{ runner.temp }}/node-compile-cache` 写入 `$GITHUB_ENV`，因此 lane 中后续每个 step——`pnpm/action-setup`、store 路径探测、安装、Playwright 安装和测试门禁——都会继承该变量。必须用注入而非 job 级 env：`runner` 上下文在 job 级 `env` 不可用（与早前 TMPDIR 工作相同的约束）；而仅给门禁 step 设 step 级 env 会让更早的 pnpm 调用继续写根分区 `/tmp`。sandbox（bwrap/Landlock）未授权 `runner.temp` 路径的受限子进程会继承该变量但**静默跳过缓存**——已在虚拟机上验证：`NODE_COMPILE_CACHE` 指向 bwrap 内未授权路径时，`node` 正常运行（exit 0），与 `mkdtemp` 的只读文件系统硬失败不同。编译缓存按设计是尽力而为；写失败只是缓存未命中，不是崩溃。 + +## 验证 + +- VM 探针：`NODE_COMPILE_CACHE=/data_local/ci/compile-cache-probe node -e 'require("node:fs")'` 在数据盘写出了 `v22.23.2-x64-*` 缓存子目录（位置切换生效）。 +- VM 探针（bwrap）：`NODE_COMPILE_CACHE` 指向 bwrap profile 未授权的路径时，`node` 正常运行（exit 0）——缓存写失败被容忍。 +- `scripts/ci-workflow.spec.ts` 断言每个 Linux lane 都在 `pnpm/action-setup` 之前把 `NODE_COMPILE_CACHE=${{ runner.temp }}/node-compile-cache`（`$GITHUB_ENV` 的 `KEY=VALUE` 行）注入 `$GITHUB_ENV`；位置断言在注入移出首次 pnpm 调用之后时会失败。 +- CI lane：三个必需的 Linux job（默认 hosted，`DSH_CI_FAILOVER_LINUX` 时自托管 `vm-backup`）会在新 env 下跑完整套件；缓存处理回归会表现为 lane 失败。 + +## 备选方案 + +### 为什么不彻底禁用编译缓存？ + +`NODE_DISABLE_COMPILE_CACHE=1` 会立即停止根分区增长，但会放弃每次运行的启动加速，而缓存是 Node 正当有用的特性（由 pnpm 和 TypeScript 显式启用）。重定向在保留收益的同时把成本移出受限分区。 + +### 为什么不把 `node-compile-cache` 纳入 `dsh-*` 清理？ + +CI 清理（残留清理改动中新增）针对测试残留；编译缓存是缓存而非残留。每次运行删掉它会丢弃缓存本要提供的加速。重定向是结构性修复：缓存的增长移到为它准备的卷上。 + +### 为什么不用 job 级 env 或只给门禁 step 设 env？ + +`runner` 上下文只在 step 级 `env` 可用；job 级 `env` 会求值为空字符串（GitHub contexts-availability），静默让缓存留在根分区。只给门禁 step 设 step 级 env 也只覆盖那一个 step：lane 中更早的每次 pnpm 调用（setup、store 路径探测、安装）仍会写根分区 `/tmp`。在 checkout 与 `pnpm/action-setup` 之间的 step 注入 `$GITHUB_ENV`，使变量在 lane 首次 pnpm 调用之前生效，一个 step 即可覆盖整条 lane。 + +## 后果 + +- **买到**：Node 编译缓存不再消耗根分区 inode；该来源的 inode 压力被移除且不损失缓存的启动收益。缓存现在位于数据卷上的 per-runner `_workNN/_temp`。 +- **代价**：缓存在 `runner.temp` 累积，而 runner 不会在 job 之间清空它（早前实测）——但在数据卷（inode 用量约 1%）上无碍。 +- **代价**：没有 `runner.temp` 授权的受限子进程会为其自身的 `node` 调用跳过缓存；这是缓存未命中而非失败，符合 Node 的尽力而为契约。 +- **代价**：改动只涉及 CI 配置；本地开发保持默认 `os.tmpdir()` 位置。 diff --git a/.agents/notes/implemented/process/2026-09-06-evidence-driven-performance-skill.i18n.yaml b/.agents/notes/implemented/process/2026-09-06-evidence-driven-performance-skill.i18n.yaml new file mode 100644 index 0000000000..53de712240 --- /dev/null +++ b/.agents/notes/implemented/process/2026-09-06-evidence-driven-performance-skill.i18n.yaml @@ -0,0 +1,6 @@ +# Bilingual-pair consistency record (docs/i18n/README.md): the git blob hash of each +# side as of the last confirmed-consistent state.

Its existing image-keyed apt cache restore/save also supplies default-branch cache production, so it needs no separate cache-seeding job. The native Linux and Windows serial aggregates do not invoke Wine. Keeping Wine hosted avoids shared-host apt transactions and shared Wine-prefix cleanup on the persistent Linux VM.

Master pushes retain scheduled checks without shrinking the release matrix. + +**Fold Wine into a self-hosted serial aggregate.** The aggregate does not already cover Wine.

Build, cache, deployment, protected-image verification, and comment semantics remain unchanged. The [sizing reference](../../../../.github/preview-sizing/README.md) owns comparison requirements. The separate CI [failover runbook](2026-07-26-ci-failover-runbook.md) retains its independent runner-switch decision; previews do not use those switches. + +### Measurements + +[Experiment 34012729982](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34012729982) succeeds for all eight size/cache combinations plus one cache seed. Every measured job checks out SHA `9149d7e7ef945b5601711badd3cf63d58ab384f5`, uses Node 24.19.0 and pnpm 11.7.0, and executes immutable install, full workspace build, preview/VFS packing, and local upload shaping with gzip integrity verification. Warm jobs restore one exact run-private pnpm cache; cold jobs skip restoration but contain pnpm bootstrap files. No compiled outputs are restored. + +| Runner | Cold / warm job seconds | Rounded minutes each | USD each | Workspace seconds cold / warm | Preview seconds cold / warm | +|---|---:|---:|---:|---:|---:| +| standard, 2 vCPU | 202 / 203 | 4 | 0.024 | 138.92 / 147.21 | 12.65 / 12.94 | +| larger, 4 vCPU | 177 / 162 | 3 | 0.036 | 124.21 / 114.86 | 10.77 / 9.88 | +| larger, 8 vCPU | 154 / 154 | 3 | 0.066 | 110.51 / 110.77 | 9.20 / 9.21 | +| larger, 16 vCPU | 124 / 125 | 3 | 0.126 | 90.57 / 84.99 | 7.62 / 7.33 | + +Using [published rates](https://docs.github.com/en/billing/reference/actions-runner-pricing), measured jobs total $0.504; the 60-second standard seed adds $0.006. The $0.510 gross compute estimate includes setup, restoration, measurement upload, and cleanup, but excludes storage and account discounts. Standard costs 80.95% less than 16-core and 33.33% less than 4-core in each sampled cache state. It adds 78 seconds against the corresponding 16-core job. + +Standard jobs expose two vCPUs and 7.75 GiB RAM. Workspace maximum process RSS is 2.86 / 2.76 GiB; preview maximum process RSS is 0.76 / 0.74 GiB. Both complete without an OOM or timeout. GNU time RSS is not simultaneous process-tree memory. These samples establish successful execution, not a permanent memory guarantee. + +The comparison fixes source, lockfile, commands, and runtime versions, not physical CPUs or image release: standard and 4-core use image 20260831.293.1; 8-core and 16-core use 20260823.283.1. CPUs vary among AMD EPYC 9V74/7763 and Intel Xeon 8370C/8573C. One sample per cache state measures the offered labels, not isolated CPU scaling or statistical repeatability. + +The experiment does not deploy or access Cloudflare credentials. Measurement upload takes zero to one second; warm-cache restore takes six to ten seconds. For context, [production job 101428009994](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34011495156/job/101428009994) spends 14 seconds uploading, one second verifying, and two seconds commenting on a different SHA. Adding that overhead to this experiment is a projection, not a measured standard-runner publication result. The actual PR preview workflow owns deployment confirmation. + +## Alternatives considered + +**Keep 16-core.** It provides the shortest measured job, but costs $0.102 more per sample for a 78-second improvement. Preview builds do not justify that premium for this cost-focused decision. + +**Select 4-core or 8-core.** Both succeed and shorten builds, but their rounded sample costs exceed standard Ubuntu. Four-core retains more RAM and disk headroom if future workloads exhaust standard capacity; such a change requires new measurements. + +**Move to self-hosted.** Rejected by scope: previews remain on GitHub CI. The existing Linux and Windows registrations can share persistent hosts; their dependency, store-volume, and cleanup assumptions do not apply to fresh hosted VMs. No failover or trust condition changes. + +## Consequences + +Previews trade approximately 78 seconds of sampled build-job latency for lower compute cost. Production Cloudflare latency, image rollout variance, future build growth, and broader success rates remain observable limitations. No hourly or monthly savings are extrapolated from this single experiment. The temporary benchmark workflow and its safety test are absent from the final tree; the experiment commits and linked run preserve the method and evidence. + +The executed [focused regression](../../../../scripts/preview-workflow.spec.ts) pins hosted routing, PR triggers and permissions, immutable full builds, restore-only caching, publication shaping, protected-image checks, and idempotent comments. A physical self-hosted routing mutation fails its routing assertion; restoration passes all three tests.

This matches the direct-CI calibration method of the [63 ms Session-reopen budget](../../../../benchmarks/session-open/session-open.bench.ts), rather than relabeling the M4 reference as hosted evidence. The 238 ms budget remains below the isolated original implementation’s 246.130875 ms M4 median. + +Deterministic controls call the same `assertRequestHistoryBudget` assertion as the timed case.

Applying this shortcut to the shared helper would weaken every caller, including restore and projection paths. + +**Trust every Session message or cache message ids.** Restore explicitly permits owned unfrozen data; replacements can preserve an id while changing identity and content. Only completed traversal of that exact object proves the request's requirement. + +**Retain a strong Set or share a global proof cache.** Strong references extend old history lifetime. Global caching expands ownership beyond the Agent and is unnecessary for repeated requests from one loop. + +**Remove downstream projection freezes.** Projected file/image/replay messages are distinct values with separate ownership. Optimizing them requires their own evidence and is not implied by freezing canonical history. + +## Consequences + +Request construction still scans message identities and allocates a fresh array; it avoids recursively traversing already-proven history. Each loop pays one complete traversal for restored history. Local headers remain a per-request cost. Message values, request markers, previous request snapshots, cancellation, and serialized SDK outputs keep their existing behavior. + +The [focused tests](../../../../packages/core/agent-loop/tests/request-freeze.spec.ts) exercise shallow-frozen restored roots with mutable descendants, wrapper identity and mutability, successful-only provenance, repeated requests, same-id compaction replacements, a fresh loop, nested tool schemas, adapter and `NO_ADAPTER` stop arrays, held requests, and live cancellation. Reconstruction and cancellation suites cover adjacent loop semantics. Performance measurements use the unchanged [continuation workload](../../../../benchmarks/agent-continuation/workload.ts), not a smaller synthetic microbenchmark. + +Validation runs 646 Agent-loop and LLM tests with 100% statement, branch, function, and line coverage of agent.ts. Keyless TypeScript SDK bash-tool and multi-turn snapshots pass against rebuilt libraries. Python sdk-minimal and sdk-snapshot checks pass against an independently packaged node24-macos-arm64 executable. Neither SDK requires an expected-output change. The packaging deploy temporarily removes workspace dependency links; a frozen-lockfile install restores them before source checks, without a tracked dependency change. + +The active immutability, message-identity, observable-state-machine, and backend-baseline notes remain independently useful; none is fully superseded or archived.

Work can move among `open()`, `SessionHandle.read()`, Session restoration, and projection, while the first history page and cold Agent resume add separate orchestration above those operations. A single `heapUsed` sample without prior GC also cannot distinguish data still retained by the Session from reclaimable migration temporaries. + +## Decision + +Linux pull requests run a required `node 24 / benchmarks` job that executes `pnpm run check:ci:bench` → `pnpm run test:bench`. The private `@deepseek-ai/dsh-benchmarks` workspace owns benchmark-only dependencies. The command first builds workspace libraries and dedicated workers under `benchmarks/.dsh-build/`, then invokes `vitest.bench.config.ts`. The [standard hosted runner decision](2026-09-06-standard-hosted-benchmark-runner.md) owns runner selection and the outer job timeout. The job runs the benchmark lane alone; Vitest runs one file at a time and only prepares input, starts measurement children, aggregates results, and enforces budgets. Every timed Node CPU path executes compiled JavaScript under plain Node with `NODE_OPTIONS` removed and no TypeScript loader; bare workspace imports therefore resolve from `benchmarks/node_modules` through package exports to built `lib/` entries. + +Required performance gates live under top-level `benchmarks/`, grouped by measured user path rather than package ownership. Host files use `*.bench.ts`, Client-face files use `*.bench.client.ts`, and scenario-specific workers and fixtures stay beside their benchmark without a benchmark suffix. Package-local `.perf.ts` files remain non-gating diagnostics; `scripts/` owns orchestration rather than benchmark cases. + +The Session benchmarks synthesize a released-v0 input from fixed parameters: 200 turns with 500 text deltas and 125 reasoning deltas per turn, for 127,400 logical events. The input uses Zstandard with fixed logical-row grouping and frame partitioning, so every run processes the same events, bytes, and frame distribution. The fixture constructs the immutable released-v0 physical rows directly instead of depending on a current-runtime historical encoder; compression and every measured read or migration entry point still use production code. Setup writes the input into a private temporary directory for each sample before timing starts; benchmarks never use recorded Sessions. + +Every Session endpoint runs at two user-lifecycle points. `first-open` starts with only the released V0 generation and includes migration; read-only consumers do not publish a successor, while writable Agent resume does. Setup produces `post-upgrade-reopen` once through that same production migration outside measurement, then copies both the unchanged V0 predecessor and published V2 successor into each sample root. Reopen samples use a fresh process, so they measure an upgraded user's later disk open without migration or process-local caches. + +Each access-kind and endpoint sample runs in a fresh compiled Node child process. Module imports, Host service initialization, and fixture preparation finish before measurement; the measured process performs no extra parse warm-up. Normal-heap mode runs five independent samples, reports every sample plus minimum, median, and maximum, and enforces access-specific fixed budgets against the median. Another child runs the same path under a fixed 128 MB old-space limit and checks only that it completes; extra GC caused by the constrained heap does not enter the normal timing baseline. + +The lane contains three independent Session-opening benchmarks and retains the Client-fold benchmark: + +| Benchmark | Measured path | Timing metrics | +|---|---|---| +| Phase profile | Executes the real persistence open, handle read, Session restore, and projection for both first open and post-upgrade reopen | `openMs`, `readMs`, `sessionRestoreMs`, and `projectionMs` each have a fixed budget; read-only migration belongs to first-open `openMs`; successor encoding, verification, and publication belong to writable Agent resume | +| First history | Reads each access kind through the Host Session history controller until it produces the first paginated snapshot | Separate first-open and reopen end-to-end budgets; each includes source stat, reading, restoration, projection, pagination, and snapshot construction, while first open additionally includes migration; both exclude Gateway network transport, Client fold, and browser paint | +| Agent resume | Calls `ctx.agents.resume()` for each access kind until Agent creation, setup, publication, and loop startup finish | Separate first-open and reopen end-to-end budgets; neither path runs after first-history or reuses that benchmark's cache | +| Client fold | Folds small and large v2 history windows through the real `ConversationNodeAssembler` and every Chat Definition | The large window's absolute time and scaling relative to the small window each have a fixed budget | + +The phase profile invokes each layer's production entry point explicitly and does not copy any decode, migration, restore, or projection algorithm. First-history and Agent-resume each run their real higher-level entry point against fresh first-open and reopen roots, so component measurements do not stand in for end-to-end results and one scenario cannot warm another's process or Session cache. The sum of the four phases is diagnostic only; an outer clock independently measures each end-to-end result. + +Normal-heap mode performs a fixed pair of explicit garbage collections after Host initialization and before the cold Session is touched, then records starting memory. It stops operation timing before performing the same garbage-collection sequence while the scenario's intended long-lived objects remain explicitly reachable, then records ending memory. The Agent-resume endpoint retains the Agent, Session, complete events, and normal service caches; its `heapUsed` delta is the primary resident-Session memory budget. Every scenario also reports `external`, `arrayBuffers`, post-GC RSS, and `process.resourceUsage().maxRSS`; the 128 MB mode prevents transient allocation peaks from being hidden by endpoint collection. Explicit garbage-collection time is excluded from operation timing. + +The performance gate does not duplicate semantic assertions owned by functional tests; it requires only that the target call completes and reaches its measured endpoint. The Client-fold benchmark continues to use the real `ConversationNodeAssembler` and every Chat Definition, and requires both the large window's absolute time and its scaling relative to the small window to remain below fixed budgets. + +Budgets are calibrated per measured endpoint. Two repeated Node 24.19 x64 CI runs differ by at most 5.2% in their medians; their CPU-heavy wall times are 1.95–2.06× the Node 24.18 arm64 reference run. Except for current-generation `open`, source constants record expected reference-machine durations; `ciTimeBudget()` multiplies them by the measured 2× CI time scale and 1.25× variance headroom. Current-generation `open` uses a directly measured standard-runner expectation of 50 ms with only the 1.25× headroom, rounded up to a 63 ms budget. The retained-heap and Client-fold scaling budgets use only the 1.25× headroom because neither is a wall-clock duration. The 128 MB completion check remains an independent transient-allocation limit. The resulting first-open time limits, constrained-heap checks, and Client-fold limits all reject the known regressions. Pre-stack commit `0d7ea53743e273930a31e9e2b6ca682f21dd4ca5` is the fixed calibration and review reference; CI does not check out or execute the historical repository. Budgets are reviewed source constants and have no environment-variable override. + +## Calibration evidence + +The comparison is orthogonal by user lifecycle, not by artifact representation. Both implementations receive the same fixed V0 bytes for first open. For reopen, each implementation reads the format it considers current in a fresh process: the pre-stack reference remains on V0, while the V2 implementation reads its published V2 successor. This intentionally compares the same user's later-open experience rather than two codecs over one data structure. + +Five-sample medians on the same Node 24 reference machine establish the positive and negative controls: + +| Access kind | Implementation | Four-phase total | First history | Agent resume | Agent retained heap | 128 MB old space | +|---|---|---:|---:|---:|---:|---| +| First open | Pre-stack reference | 249.0 ms | 253.8 ms | 100.7 ms | 26.1 MB | Completes | +| First open | Repeated-snapshot regression | 4,197.5 ms | 4,284.8 ms | 4,197.9 ms | 4.4 MB | Exhausts heap | +| Post-upgrade reopen | Pre-stack reference | 251.1 ms | 253.8 ms | 100.7 ms | 26.1 MB | Completes | +| Post-upgrade reopen | Repeated-snapshot regression | 49.2 ms | 50.4 ms | 43.8 ms | 4.5 MB | Completes | + +The pre-stack implementation keeps V0 as its current format, so first open does not change its on-disk representation; its native V0 first-history and Agent-resume measurements therefore apply to both lifecycle rows. + +The [standard two-CPU run](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34023970384/job/101461539961) at `ca3ffe95dac2c55eefeb16ed9b61067bbd19ee90` uses Node 24.20.0 x64 and Ubuntu image `20260831.293.1`. Its five current-generation `open` samples are 49.2, 47.4, 49.1, 48.6, and 48.1 ms: median 48.6 ms, maximum 49.2 ms. The rounded 50 ms CI expectation gives a 63 ms limit without reapplying the 2× machine scale. The log identifies two available CPUs but not their model; it does not isolate hardware from the Node-version change. This is endpoint-specific runner calibration, not evidence of an application optimization or a new reference-machine measurement. Every other benchmark passes its existing budget. Deterministic controls reject the observed median at the historical 30 ms limit, accept it at 63 ms, reject a synthetic 75 ms reopen median, and reject a synthetic 4,000 ms first-open duration at its unchanged 550 ms limit. These controls verify budget enforcement, not a measured new regression. + +The calibrated source budgets are: + +| Measurement | Reference expectation | CI budget | +|---|---:|---:| +| First-open `open` | 220 ms | 550 ms | +| Current-generation `open` | 12 ms (historical reference; CI expectation: 50 ms) | 63 ms | +| Complete read | 8 ms | 20 ms | +| Session restore | 24 ms | 60 ms | +| Projection | 14 ms | 35 ms | +| First-open first history | 220 ms | 550 ms | +| Current-generation first history | 48 ms | 120 ms | +| First-open Agent resume | 180 ms | 450 ms | +| Current-generation Agent resume | 40 ms | 100 ms | +| Agent retained heap | 26.1 MB | 33 MB | +| Client-fold absolute time | 16 ms | 40 ms | +| Client-fold delta scaling | 2.5× | 3.125× | +| Constrained old space | — | 128 MB | + +## Alternatives considered + +**Check out the historical commit and compare it on every CI run.** Rejected because a historical checkout requires a separate install, and old and current revisions can assign work to different API phases, adding runtime, dependency, and interface drift. A fixed workload with static budgets calibrated against positive and negative controls is easier to reproduce and review. + +**Measure only first open from V0.** Rejected because migration is a one-time upgrade cost and cannot protect later opens of the settled current generation from regressions. The two access kinds need separate measurements and budgets. + +**Measure only the four component phases.** Rejected because component measurements locate cost but omit source stat, orchestration, pagination, and snapshot construction, and cannot prove that the complete first-history path remains usable and fast enough. + +**Measure only first-history or Agent-resume total time.** Rejected because an end-to-end number protects the result but cannot identify whether storage, reading, Session restoration, or projection regressed; four phase budgets retain actionable attribution. + +**Add fine-grained timing instrumentation inside production implementations.** Rejected because those probes would expand production APIs and couple the benchmark to implementation details. Tests use existing service and object boundaries; costs that those boundaries cannot attribute remain part of the end-to-end result. + +**Run measured workers from TypeScript source.** Rejected because a source loader changes module resolution and startup behavior, and causes nested workers to select source-only bootstrap paths. Vitest remains an unmeasured orchestrator; every timed worker executes the build output exactly as plain Node consumers do. + +**Use only time budgets or only post-GC memory.** Rejected because time does not reveal memory regressions, while endpoint live memory cannot expose transient migration spikes. Normal-heap post-GC deltas and constrained-heap completion cover the two risks separately. + +**Benchmark the real recorded corpus.** Rejected because corpus fixtures stay small by policy, recorded material must not become benchmark input, and re-recording would silently move the workload. + +**Run benchmarks inside an existing gate aggregate.** Rejected because aggregate gates run concurrently on one runner, so wall-clock measurements inherit neighbouring CPU load. + +**Keep each cross-package gate under one participating product package.** Rejected because Session opening spans persistence, migration, projection, Host history, and Agent resume; choosing one participant creates misleading ownership and benchmark-only package dependencies. The repository-level tree owns the integrated user path, while package-local diagnostics remain with their implementation. + +**Put benchmark cases under `scripts/`.** Rejected because scripts own commands, generators, and orchestration, while a benchmark case owns typed test files, workers, fixtures, budgets, and lifecycle cleanup. A future reporting or calibration command may consume `benchmarks/` without moving the cases there. + +## Consequences + +Every pull request pays for one required Linux job; its Session portion runs several short-lived child processes in exchange for cold caches, isolated V8 heaps, explicit GC state, and attributable failures. The repository-level benchmark tree accepts deliberate cross-package test dependencies without changing product package manifests. The fixed Zstandard workload covers both event volume and frame topology; first-open measurements protect the one-time upgrade experience, reopen measurements prevent regressions in later opens, phase budgets locate cost, first-history budgets protect user-visible waiting, Agent-resume budgets and post-GC deltas protect complete cold activation and resident memory, and the 128 MB mode protects the transient allocation ceiling. + +The Session and Node-fold scenarios do not measure network transfer, browser rendering, or recorded Sessions, and they are not a continuous performance-trend system. [Frontend performance budgets](2026-09-06-frontend-performance-budgets.md) own browser workflow measurements. A Node or runner change requires resampling the same workload and reviewing the budgets; a business-implementation change must not relax a budget without new positive and negative control data. diff

Continuation additionally measures retained heap against an initialized Host: two explicit GCs separated by an event-loop yield precede and follow the timed operation, while the idle Agent remains reachable. The measured delta therefore includes the resident historical Session and live additions, not just newly appended turns. GC and teardown are outside timing; flush is inside. Request-history retention starts after resume and is diagnostic only. Catalog peak RSS is diagnostic; no retained-heap budget claims to measure already-released child observations. + +The parent bounds every child to 60 seconds, checks timeout, signal, exit, and report independently, awaits process close, and removes private roots after failures.

SDK time expectations use the existing [calibration helper](../../../../benchmarks/support/calibration.ts): 2× shared CI time scale and 1.25× variance headroom. Request history uses the direct hosted expectation in the [request-freeze calibration](../simplification/2026-09-06-agent-request-freeze-provenance.md), without the 2× scale. Memory uses only 1.25× headroom. The scale is inherited from the existing lane's calibration, not a new Linux measurement of these cases; CI evidence remains necessary when runner characteristics change. Baseline budgets protect the measured implementation; tighter budgets belong with a measured behavior-preserving fix. + +A separate plain-Node request-history CPU profile attributes 132.876 ms of sampled self time to deepFreeze called by buildRequest during a 211.300 ms operation. This identifies repeated traversal of already-frozen history as a focused investigation target, not a proven optimization result. Catalog first/repeat timings remain separate because a second listing still reads body-bearing seeded children after observations are released. + +The shipped SDK variant completes 100 turns, 200 requests, and 800 real file reads. Its five-sample smoke totals are 1,521.773, 1,463.465, 1,689.701, 1,365.485, and 1,417.106 ms (median 1,463.465 ms); a full-suite repeat reports 1,596.183, 1,784.536, 2,120.082, 1,405.365, and 1,355.894 ms (median 1,596.183 ms). Its 1,700 ms reference expectation yields a 4,250 ms CI budget. The repeat also slows the unchanged service cases, so it is validation under variable host load rather than evidence to relax their exclusive calibration. The SDK process receives an allowlisted environment and private home/workspace. A 40-second deadline starts SDK shutdown; every path awaits the same memoized close promise before the outer worker’s 60-second deadline. Profile timing includes boot, all turns, and shutdown, reported separately; no parent-process CPU or heap metric is presented as server memory. The adapter does not serialize requests for an external model provider. + +The first Linux x64 CI measurement at commit `1dc3296eba631d51fbb3bb50e249bf3cc0fce9f6` ran on `VM-7-113-ubuntu-ci-10` with Node 24.18.1 ([run 34017868081, attempt 1, job 101444810498](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34017868081/job/101444810498)). The SDK median was 2,753.441 ms against its 4,250 ms budget, and tool-continuation retained-heap median was 22.274 MiB against 28.75 MiB. Request-history and tool-continuation time budgets failed: 785.498 ms against 550 ms and 1,077.285 ms against 850 ms, respectively. The unchanged Session-reopen open phase also failed at 31.6 ms against 30 ms. [Attempt 2, job 101447076381](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34017868081/job/101447076381) passed every benchmark on the same commit and unchanged budgets, but used `VM-7-113-ubuntu-ci-29` with Node 24.19.0. The gate runner suppressed successful child output, so that attempt supplies a passing verdict rather than raw medians. The changed runner and Node version prevent attributing the difference solely to contention or claiming stable repeated CI calibration; neither the budgets nor the shared scale are changed on this evidence. + +Catalog uses an explicit 900 ms expected CI duration and only the existing 1.25× headroom, yielding 1,125 ms without applying the reference-machine scale again. The standard two-CPU hosted `ubuntu-24.04` [run 34033336380, job 101487280801](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34033336380/job/101487280801) reports five unchanged-catalog totals of 797.374, 883.157, 858.364, 790.569, and 904.579 ms: median 858.364 ms exceeds the historical 800 ms budget. The 320 ms M4 expectation above remains historical evidence, not a CI measurement. This follows the explicit-CI calibration used by Session reopening (50 ms expected CI); shared factors, workloads, timing endpoints, and product implementations remain unchanged. Deterministic controls use the same assertion as the measured verdict: the unrounded recorded median passes 1,125 ms and fails 800 ms, while a synthetic 1,400 ms median fails 1,125 ms. A passing run on a faster host does not calibrate the standard hosted runner. + +Tool continuation also uses a 900 ms expected CI duration with 1.25× headroom (1,125 ms). At unchanged implementation `79c052ab29`, standard two-CPU hosted [run 34034524265, job 101490056074](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34034524265/job/101490056074) reports totals of 917.007, 892.091, 887.839, 905.659, and 898.252 ms: median 898.252 ms exceeds the historical 850 ms budget. The 340 ms M4 expectation remains historical evidence. The same measured-verdict assertion accepts the recorded unrounded median under 1,125 ms, rejects it under 850 ms, and rejects a synthetic 1,400 ms regression. Workload, timing, product code, and the 28.75 MiB retained-heap budget remain unchanged. + +Baseline request history uses a 600 ms expected CI duration with 1.25× headroom (750 ms).

The 220 ms M4 expectation remains historical evidence. The same measured-verdict assertion accepts the recorded unrounded median under 750 ms, rejects it under 550 ms, and rejects a synthetic 900 ms regression. This calibrates the unoptimized baseline only; workload, timing, product code, and memory budgets remain unchanged. + +## Alternatives considered + +**Repeat existing migration and first-open variants.** Rejected: those twelve cases already distinguish read-only preparation from writable publication. These cases use the current generation and begin or continue actual model work, or enumerate a corpus rather than open one Session. + +**Measure only deriveMessages.** Rejected: its incremental cache does not include complete request freezing, adapter dispatch, live append, or persistence. Actual sequential requests protect the cost the Agent pays per step. + +**Use only unseeded children with warm projection-cache rows.** Rejected: that path bypasses body observations and misses the exact inherited-cut requirement of fork children. The catalog intentionally omits the optional projection cache and reports the seeded fallback path; it does not characterize cache-hit discovery. + +**Apply an optimization and its desired budget together with the first measurements.** Rejected: a baseline-only layer remains independently mergeable and records the current workload before attribution or implementation changes. Source constants cannot be overridden by environment variables. + +## Consequences + +The lane adds four cases in three scenario groups and twenty measured workers, plus two seed processes. The integrated continuation case spans resume through completed model/tool work and durable flush. The shipped SDK workflow additionally includes profile boot, SDK transport, real file tools, and shutdown; only its model adapter is synthetic. It starts a fresh Session because the public SDK prompt API creates rather than resumes stored identities. Neither path includes network model latency, provider-specific request serialization, optional user plugins, compaction, failed tool results, images, cancellation, or browser rendering. Functional tests retain responsibility for event contents, immutable messages, tool semantics, fork lineage, and read-only versus writable side effects; endpoint counts prevent timing a skipped workload without duplicating those assertions. + +This note supplements, rather than supersedes, the Session-opening gate's isolation and calibration rationale.

Two animation frames include a rendering opportunity, not hardware presentation or a guarantee that every offscreen node painted. + +The continuation sends 120 text deltas at 16 ms replay pacing. The input witness is installed before Send; typing starts immediately after the first visible marker, without a separate pre-input animation-frame wait. Send lookup stays inside the composer seat; first/final marker lookups stay inside the latest Assistant step and retain visible-state waits. The synchronous input witness reads that same bounded reply. Whole-history text and accessibility queries add observer CPU and garbage collection to the measured interval, so reducing that observer work is benchmark repair, not product optimization. It records click-to-first-visible-reply, trusted draft typing whose first actual input event observes the first reply but no completion marker, complete reply wall time through settled persistence and the new rendered turn-tail, and Chromium main-thread task duration. The complete wall budget adds the fixed 1984 ms scripted pacing to a scaled overhead allowance; input and completion have their own enforced budgets. Post-GC browser heap and DOM counts remain diagnostics because one endpoint does not prove a leak. + +Reconnect uses three fresh compiled plain-Node children. Each creates a 100,000-delta reasoning prefix with distinct timestamps and two compact records before timing `ClientAssistantStream.replace()`. GC precedes the baseline and follows replacement while the result remains reachable; replacement time excludes both collections. The report consumes the result after collection and checks that the next dense live frame remains accepted. This measures reconstruction, not transport, rendering, or an entire reconnect workflow. + +## Calibration + +Three-sample medians on the arm64 reference machine, Node 24.19 and Chromium 149.0.7827.55, at product revision `925e012340`, establish the baseline below. An isolated repeat follows a complete workflow smoke. Each browser sample reports raw endpoint values and every page; the paging verdict uses the median of the sample maxima. Reconnect reports all child measurements. The following historical reference table uses 8 ms replay pacing and includes a two-frame wait in first-reply timing. Standard-hosted open, paging, Trajectory, and reconnect expectations are recorded separately below; other source reference constants retain these allowances. The bounded-observer 261.60 ms paging median exceeds its 260 ms reference allowance but remains below its 650 ms CI limit; the shared 2× time scale and 1.25× variance allowance produce CI limits. Memory uses only variance allowance. The shared scale originates in Node CI calibration. Both actual x64 browser runs below pass the fixed budgets on unchanged benchmark code; this supplies repeated-run evidence for these runners, not a universal browser speed ratio. + +| Endpoint | Measured median | Reference allowance | Historical CI limit | +|---|---:|---:|---:| +| Browser open | 184.62 ms | 200 ms | 500 ms | +| Slowest older page | 261.60 ms | 260 ms | 650 ms | +| First Trajectory | 136.46 ms | 160 ms | 400 ms | +| First reply | 373.72 ms | 1100 ms | 2750 ms | +| Stream main-thread task | 1053.87 ms | 1800 ms | 4500 ms | +| Draft typing | 487.35 ms | 500 ms | 1250 ms | +| Complete response | 1366.36 ms | 1000 ms overhead + 992 ms pacing | 3492 ms | +| Reconnect replacement | 13.83 ms | 16 ms | 40 ms | +| Reconnect retained heap | 23.03 MiB | 24 MiB | 30 MiB | + +Draft typing spans 124.97–504.96 ms across the three isolated samples; the reference remains 500 ms and the scaled CI limit covers that observed spread; the median is not a per-keystroke bound. No budget is an environment override. Temporary zero allowances exercise every rejection path; these negative controls prove enforcement, not an optimization or a historical regression. A separate control waits for the final reply marker before typing and fails the actual-input overlap assertion. The compact synthetic JSONL is 3,262,577 bytes; all three corrected samples report an overlapping trusted input event and end after the 241st rendered turn-tail. + +### Actual CI runs + +[Run 34020120425, benchmark job 101451135853](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34020120425/job/101451135853) passes the complete benchmark inventory at `6d1ba089e5052680961825c08aa4de19b4fe137a`.

Post-GC browser heap is approximately 52.94 MiB in the first run and 53.00 MiB in the second, with 17,064 DOM elements in both; these remain diagnostic endpoints. Both runs support the existing budgets on these runners, not a universal 2× browser speed ratio. Draft-typing medians vary from 932.746 ms to 142.148 ms because the endpoint measures the entire typed draft, including scheduling and Playwright actionability, rather than a per-key latency guarantee. These are self-hosted measurements, not standard-hosted calibration; no product optimization is claimed. + +### Standard hosted expectations and input scheduling + +[Run 34033336246, job 101487216170](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34033336246/job/101487216170) on standard hosted Ubuntu with two CPUs records reconnect replacements of 46.574411, 46.067910, and 44.193704 ms, with 23.028 MiB retained heap. The endpoint-specific expectation is 50 ms; the existing 1.25× headroom gives a 63 ms integer ceiling. The 30 MiB memory budget and shared machine factor remain unchanged. Browser open records 681.276514 and 541.051233 ms before the third sample fails input overlap; both exceed the historical 500 ms limit. Repeated hosted open measurements below set its expectation and ceiling. Deterministic controls pass these recorded values and reject values above the new ceilings through the same assertions as the measured verdicts. Complete repeated hosted verdicts remain required; the two open values are not a three-sample median. + +A local diagnostic with temporary 3× Chromium CPU throttling reproduces the overlap failure: the first marker becomes visible at 1321 ms, two animation frames finish at 1370 ms, and the composer click finishes at 1660 ms; the actual input is trusted but already sees DONE. Removing the frame wait and installing the witness before Send still leaves a run with first visibility at 1415 ms and click completion at 1726 ms, after the original 992 ms scripted stream. The fixed 16 ms cadence keeps the same 120 deltas and payload, providing 1984 ms of scripted pacing for this workload. Only that pacing term changes in the complete-wall allowance (4484 ms); input, first-reply, and main-thread overhead allowances remain unchanged. With the same diagnostic slowdown, three 16 ms samples reach first visibility at 1307/1479/1599 ms and accept trusted input before DONE; their post-DONE controls reject it. The diagnostic is not a CPU-ratio calibration. Each measured sample still requires trusted input while FIRST is present and DONE absent; a post-measurement trusted key after DONE must fail that same assertion. Host settlement and the 241st rendered turn-tail remain completion witnesses. + +[Run 34034524861, job 101490135303](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34034524861/job/101490135303) records three complete browser samples with trusted input overlap and passing post-DONE rejection controls. Slowest-page samples are 843.941625/672.834329/684.461818 ms (median 684.461818); first-Trajectory samples are 605.788061/367.754027/485.931656 ms (median 485.931656). Their endpoint-specific hosted expectations are 700 and 500 ms, with the same 1.25× headroom producing 875 and 625 ms limits. Recorded-median controls reject the historical 650/400 ms limits, accept these hosted limits, and reject one millisecond above each limit through the measured verdict's assertion. Open, first reply, main-thread task, input, and complete-wall medians are 713.910/1486.206/2806.415/947.398/2986.983 ms; only the open limit is recalibrated by the repeated measurements below.

The endpoint-specific expectation is 900 ms, rounding up the larger repeated median rather than adding an epsilon to the 875 ms limit; unchanged 1.25× headroom gives 1125 ms. The same enforced assertion accepts the recorded median, rejects it at both historical 500 and 875 ms limits, and rejects a synthetic 1126 ms value at the current limit. All three samples retain trusted input overlap and post-DONE rejection; every other frontend median remains within its unchanged limit. This calibration does not claim a green CI run. + +## Alternatives considered + +**Use the Node fold as paint evidence.** Rejected because it never performs DOM mutation, layout, or browser scheduling. The focused reconnect case likewise makes no GUI speed claim. + +**Promote the entire manual browser diagnostic into CI.** Rejected because its 1,000-session sidebar and 100-turn soak cover a much broader workload. The bounded required case reuses its shipped scaffold and measurement approach without importing a test module or changing the manual inventory. + +**Coalesce active reconnect chunks.** Rejected as a benchmark shortcut: Client entries expose per-member ordering and timestamps to conversation definitions. The benchmark retains that production behavior; reducing retained entries requires a separate semantic design, not copied product algorithms or a synthetic approximation. + +**Search the entire loaded history for every stream marker.** Rejected because Playwright injects text and accessibility scans into the same renderer whose CPU the benchmark measures. Scoping queries to the composer and latest Assistant preserves visible completion checks without making observer cost proportional to loaded history. + +**Measure stream CPU alone.** Rejected because transport stalls and final-settlement delays can leave main-thread CPU low. The independent input, first-reply, and complete-wall budgets cover those waits. + +## Consequences + +The benchmark layer changes no product implementation or user-visible behavior. It adds approximately fifteen seconds of local browser/reconnect execution plus Web build and browser provisioning to the existing isolated CI lane. A fresh browser discards previous caches, but each workflow deliberately retains its own loaded history and previously activated Trajectory during continuation. + +The baseline is independently mergeable and protects current performance; optimization layers tighten budgets only with repeated measurements and focused semantic tests. It does not cover sidebar cardinality, an hours-long soak, GPU presentation, real model latency, a published Host launch, or reconnect rendering. The [Web browser lane](2026-07-24-web-gui-browser-e2e-lane.md) retains its separate threshold-free manual diagnostics and functional browser tests; calibrated required measurements belong to this benchmark lane. The existing Session performance note remains active because it owns Node calibration and persistence rationale; this note extends rather than supersedes it. diff --git

Conversation messages are surface events (`user/message`, `assistant/message`, `tool/result`) folded in seq order by `Session.deriveMessages()`; the system prompt is the `system` field of the log-only `request/header` snapshot, and each DeepSeek serializer prepends it as wire message 0 (`serializeRequest`, `serializeRequestWithImages`). The [reconstructable-requests Agent Note](../../implemented/architecture/2026-07-05-reconstructable-requests.md) made both halves durable, but it left one model-visible fact with two homes: the surface owns the messages, the header owns the message in front of them. + +That split forces every reader of "what did the model see" to join two sources. The compaction summarizer (`buildSummarizationInput`) copies `header.system` in front of the region's derived messages; `dsh-token-meter` estimates the system prompt from the header while pricing every other message from the surface; the Web request-prompt card, the trajectory view, and the snapshot normalizer's `{{system}}` placeholder each read the header on their own. The loop's change detection is also split: `headerEquals` compares `system` byte-for-byte beside `config` and `tools`, so a prompt change and a tool change are indistinguishable in the log (`request/header` reason `change`) even though they are different operations on the conversation. + +The split also blocks the next step. A model that accepts a mid-conversation `system` message as a prompt replacement needs the harness to append a system-role message to history; with the prompt living in the header there is no surface representation to append, and the header would have to be frozen by special case.

The `dsh-agent-loop/invariant` companion keeps comparing the rebuilt request against the frozen one, now with the system message inside `messages`. `docs/architecture.md` records the new loop step order: claim, assemble, project system prompt, project runtime context, pre-step, commit system node, commit user messages, build request. + +### Consumers retargeted + +| Consumer | Today | After | +|---|---|---| +| DeepSeek serializers (`serializeRequest`, `serializeRequestWithImages`) | prepend `options.system` | serialize `options.messages` only; `GenerateOptions.system` remains for direct one-shot callers such as the summarizer and title providers | +| `compaction-basic` `buildSummarizationInput` | `header.system` + region messages | node 0's derived message + region messages, still a genuine prefix of the routed request | +| `compaction-basic` `selectCompactableRange` | head-anchored at `surfaceNodes[0]` | anchored at the first non-system node; node 0 is never inside a compaction range | +| `dsh-token-meter` system estimate | `header.system` length | the system node is priced like every other surface node; the context breakdown labels it by its source plugin | +| Web request-prompt card, trajectory request-header node, request inspection | read `header.system` | read the `system/message` node; the card keeps its collapsed inspectable presentation and is never a chat bubble | +| Snapshot normalizer `{{system}}` placeholder, plan-mode tests asserting `header.system` | header | the system node's text | +| TypeScript and Python SDK expected outputs | no system event | include the `system/message` event | +| Human transcript projections (`isAppendSurfaceEvent` readers) | no system events | skip `system/message`; it is model history, not conversation | + +`RuntimeContextProjection` and `SystemPromptProjection` are symmetric: both watch owned surface nodes and their shadowing through `sourceEventSeqs`, and both hand the loop an uncommitted message that `turn()` commits.

When the rendered prompt differs from the effective prompt: + +| Route capability | Prefix state | Operation | +|---|---|---| +| none | any | replace node 0 | +| `in-history` | the current request series continues (no compaction since the last request, no tools or config change) | append a new `system/message` before the step's `user/message` events | +| `in-history` | a new series starts (compaction replaced the surface, or `request/header` records a `change` for tools or config) and no mid-history system node survives | replace node 0 with the current prompt | +| `in-history` | a new series starts but a mid-history system node survives | append a new `system/message`; node 0 stays as it is | + +The third row exists because a series start already costs the cache; folding the prompt back into node 0 keeps the history short. The fourth row exists because the surface has no delete operation: replacing node 0 while a later system node survives would leave the model reading the later, stale node as authoritative, so the loop appends instead. In-history mode never rewrites node 0 while any later system node survives. + +Resume follows the mid-session rule. A new loop instance restores the effective prompt from the log and, when the freshly rendered prompt differs, appends — the provider cache may still be warm across a process boundary, and the `resume` header is not a series start. + +### Presentation and accounting + +A mid-history `system/message` uses the same collapsed request-prompt inspection card as node 0, labelled as a prompt update at its position in the request; it is never a chat bubble, transcript projections skip it, and SDK projections expose it as a typed event. `dsh-token-meter` prices it like any other surface node, so the per-step context breakdown shows the accumulated cost of retained prompt versions until compaction shadows them. `cacheReadTokens` on the following `assistant/message` usage is the observable effect: for a capable route the value covers the prefix through the last cached message; for a non-capable route it drops to the shared-prefix detection floor. + +### Verification plan + +- Unit tests in `dsh-agent-loop` for the projection: append on a mid-series change, replace on a series start without surviving mid-history nodes, append on a series start with one, append on resume, no operation when unchanged, and replace-only behaviour for a route without the capability. +- Unit tests in `dsh-llm-deepseek` for catalog validation (`systemPromptUpdate` accepts `'in-history'` only) and for `prepareCall()` surfacing the field. +- A keyless recorded snapshot under `snapshots/` whose composition declares the capability on the mock route and toggles plan mode mid-session, pinning the appended `system/message` and the untouched node 0; TypeScript and Python SDK expected outputs include the appended event. +- A real-API e2e that runs two steps with a prompt change against a capable route and asserts that the second request's `cacheReadTokens` is at least the first request's prompt token count. It resolves its route from the standard credential and base-URL mechanism and self-skips when no capable route is configured. + +## Alternatives considered + +**Send only the changed sections as a delta.** The model treats the latest system message as the complete prompt, so a delta would silently drop every unchanged section. Rejected on the model contract. + +**Enable in-history mode by plugin config instead of a model capability.** A deployment flag could pair a non-capable model with appended system messages, which such a model would read as ordinary history at best. The capability belongs to the route that honours it; the adapter catalog already carries per-model capacities. Rejected. + +**Always append, never re-baseline.** One rule, but node 0 would stay stale for the life of the session and every request after compaction would carry the stale head plus the replacement. Re-baselining at a series start costs nothing extra because the cache is already lost there. Rejected. + +**Re-baseline on every resume.** Accepts one cache miss per process restart for a simpler resume path. The cache persists across restarts for hours to days, and the log already carries what resume needs. Rejected. + +**Place the system message after the step's user messages.** Both positions sit after the cached prefix, but the model then reads the instructions after the input it must apply them to; system-before-user matches the leading position's ordering. Rejected. + +## Acceptance criteria + +- `DeepSeekCatalogModel.systemPromptUpdate` is validated at load, exposed through `LlmResolvedModelInfo`, and returned by `prepareCall()`; a misspelt value fails at load. +- On a capable route a mid-series prompt change appends `system/message` before the step's `user/message` events and node 0 is unchanged; on a non-capable route the same change replaces node 0. +- On a capable route a series start with no surviving mid-history system node replaces node 0; with a surviving one it appends. +- A resumed loop instance whose rendered prompt differs appends on a capable route. +- The recorded snapshot and both SDK expected outputs pin the appended event; the e2e asserts the cache-hit inequality when a capable route is configured and skips otherwise. +- The `dsh-llm-deepseek`, `dsh-agent-loop`, and `dsh-system-prompt` READMEs document the capability, the decision rule, and the KV Cache effect; `docs/config-catalog.md` lists the field. + +## Risks + +- The model contract is unpublished; the note records it as provided. If the released model narrows it (for example, honouring only the latest system message within a bounded window), the decision rule needs a re-baseline trigger beyond series starts. +- Retained prompt versions accumulate in history until compaction shadows them. Each version costs its tokens on every request in the series; a deployment whose prompt changes on most steps would be better served by moving that fact into runtime context. +- A proxy that rewrites or reorders system messages breaks the replacement semantics silently; the e2e's cache-hit assertion is the detector. diff --git

Deferral is not deletion, and viewport highlighting is not full virtualization. +- Stabilize identities and narrow subscriptions so one changed node does not invalidate an entire history; preserve update ordering and immediate-event behavior. +- Prefer a suitable data structure to repeated shifting, scanning, or rebuilding. Measure the whole consumer path, not just the isolated container operation. +- Use revision-keyed reuse or singleflight only with explicit invalidation, bounded retention, independent waiter cancellation, and disposal ownership.

It opens a synthetic 240-turn Session, loads every older page, visits Trajectory, returns to Chat, and submits a paced reply while typing another draft. The shipped Web scaffold owns the isolated home, persistence, replay adapter, and loopback listener; Chromium loads the built Web artifacts, not a replacement development server. + +## Run + +`pnpm run test:bench` builds libraries, workers, and Web artifacts before running the serial benchmark inventory. With artifacts already built, select this directory through `pnpm exec vitest run --config vitest.bench.config.ts benchmarks/long-session-browser`. Install Chromium through the benchmark workspace before the first run. + +## Measurements + +Three fresh browser processes and scaffold worlds produce raw samples and median verdicts. Open and paging end after the expected transcript state and two animation frames; this includes a rendering opportunity, not a hardware presentation timestamp. Paging reports every page and gates the median of each sample’s slowest page. Stream reports first visible reply, trusted draft typing, complete reply wall time, and Chromium main-thread task duration. Send lookup is scoped to the composer seat; reply-marker lookups and the input-event text witness read only the latest Assistant step, avoiding repeated whole-history text and accessibility scans. The input witness is installed before Send, and draft typing starts as soon as the first marker is visible, without an extra pre-input animation-frame wait. The actual first input event must observe an unfinished reply; completion waits for the new rendered turn-tail after Host settlement. After measurement, a trusted keystroke after DONE must fail the same overlap assertion. Open, the slowest older page, and first Trajectory use standard-hosted expectations of 900/700/500 ms. Shared 1.25× headroom gives limits of 1125/875/625 ms respectively; stream endpoint overhead budgets are unchanged. Heap after forced GC and DOM counts are diagnostics, not leak budgets. + +The fixture contains mixed-language prompts, prose, reasoning, 20 code fences, and 40 synthetic tool results. Every historical Assistant includes a compact stream built by the production accumulator from matching reasoning, text, tool arguments, usage, and finish chunks.

The manager derives these internal conditions from `Agent.whenIdle()`, `Agent.inbox.hasPending`, the owned-child set, and an Activation generation that invalidates stale observations, rather than maintaining a second execution state machine. After the final Session flush, the child-lock decision uses the synchronous task entry of `Agent.runMaintenance()` to claim the idle phase and close admission in the same JavaScript turn. This conservative rule does not distinguish delivery modes: context parked by `Agent.inject()` can keep an idle Activation and its live ancestors resident until a waking delivery claims it, a queue mutation removes it, or manager teardown discards it. -The Agent inbox is the only queue.

Every Agent message uses `Agent.steer()`: an idle target starts a turn, while a running target claims it at the nearest step boundary. The browser `subagent.prompt` Remote separately carries `delivery: 'queue' | 'steer'` through the same internal admission path; Queue opens a later FIFO turn, while Steer retains the Agent loop's best-effort nearest-step behavior and the message's human source. Successful delivery returns the accepted `MessageId`; the existing `agent/inbox/inserted`, `agent/inbox/claimed`, and `agent/inbox/discarded` events remain the message-lifecycle observations, and the continuation layer defines no second queue. Authority comes from the exact live sender. Parent-to-child delivery requires the target's `SessionHeader.parentSession` to name the sender; child-to-parent delivery requires the sender's resident Activation to name the target. Siblings, ancestors beyond one edge, self-targets, stale Agent objects, and one-shot children are rejected. Each accepted message is framed as `Agent sent a message:` and records `AgentMessageSource`; provenance records the sender but grants no authority. -For `startContinuable()` and `sendMessage()`, the caller signal owns lookup, materialization, and admission only until inbox acceptance.

Afterwards the manager owns the Activation independently: later caller cancellation neither cancels the accepted turn nor disposes the child. The public subagent service exposes no caller-selected Agent-message scheduling; browser human Queue and Steer remain internal adapter choices. + +Live queue occurrence mutation remains in the Session domain. `session.updateQueue` admits ordinary Edit, Remove, and QueueDock Steer for a live subagent-owned Agent only when its current projected identity is continuable and its descriptor sequence is in that child's own non-seed suffix. The identity projection folds descriptors last-wins so a child descriptor supersedes descriptors retained from fork lineage; the own-suffix sequence check prevents a seed-only ancestor identity from authorizing mutation. One-shot, missing, unknown, corrupt, or cold children remain rejected, and queue mutation never cold-resumes a child. The target Session id is the human authority for these mutations, including pending `nextStep` steering or injected context. Steer requires a queued `MessageId` and an Agent that reports running when the command begins; cancellation after admission uses the Agent's accepted waking `nextTurn` fallback. Edit rewrites content under the same `MessageId`, and both Edit and Steer complete their Inbox work synchronously, so settlement observes only the final state. `agent/inbox/claimed` and `agent/inbox/discarded` wake the watcher to re-read whether any pending occurrence remains; this lets direct Agent delivery resume parked work and lets removing the last parked occurrence settle an idle child. The [human inbox-control Agent Note](../../.agents/notes/implemented/feature/2026-08-27-continuable-subagent-human-inbox-control.md) owns these semantics. `SubagentRuntime.interrupt(targetSessionId, authority)` is the one public stop: it authorizes synchronously, issues `Agent.cancel(cause, { keepInbox: true })` on the live target, and returns without awaiting quiescence. The Activation, its unclaimed pending inbox work, and published descendants are untouched; work already claimed into the interrupted turn is not requeued. Once the interrupted driver is idle, a waking send resumes the parked FIFO queue. An absent target — unknown, one-shot, or already settled — and a manager-less composition are accepted no-ops.

Prompt retries whose `requestId` is already queued or logged return the original acceptance without inserting another message. Create and fork are the only operations that create a new Agent directly. The service applies one preset-aware resume policy and subagent ownership fence to its own methods and to the Typert Agent and Session lookups used by other Remote namespaces. Queue mutation has one narrow exception: a live child whose current projected identity is continuable and comes from its own non-seed suffix accepts the ordinary Edit, Remove, and QueueDock Steer actions across both inbox destinations. One-shot, missing, unknown, corrupt, seed-only, or cold children remain rejected without resume. The skill catalog uses a live Agent when present or the recorded preset's standing scope when cold, so listing never starts an Agent. The Client adapter exposes `SessionEventStream`, a Gateway `RemoteJournalStream` bound to one ordinary or direct-subagent address. It opens follow before the initial page, publishes only contiguous `replace`, `prepend`, `append`, and `settle-assistant` changes, and repairs reconnect or sequence gaps through a tail page. Backwards paging has two verbs: `loadOlder()` pulls one 50-message page, and `loadThrough(seq)` — the turn-jump loader — loops 200-message pages until the window covers the target seq, lowering a shared target on repeated calls, stopping on a page that makes no progress, and reporting busy through the same `loadingOlder` snapshot bit. The Web adapter explicitly opts into cursorless Assistant frames: each opening carries the active attempt's `startedAfterSeq`, `nextIndex`, and compact stream, and every stream member becomes a Client-only `assistant/live-chunk` entry ordered between durable cursors. The Host captures a follower-local arrival ordinal with that baseline and suppresses buffered frames at or before the cut; a replacement Agent may restart frame revision at one. A durable `assistant/message` or `assistant/attempt` arriving after an active opening stays staged only when its seq follows `startedAfterSeq` and its Turn and Step match; the matching end type, seq, and index publishes one named settlement delta that retires the attempt's transient rows and adds the durable entry while earlier same-step retries remain visible. Revision, dense-index, or settlement gaps for a known attempt reopen follow, while a controller that missed the start ignores unknown-attempt frames and publishes their durable settlement normally. An abandoned end publishes a settlement delta without a durable entry so its transient rows retire immediately. A durable gap-repair page has no Assistant baseline, so its held notification reopens follow once for a paired page and baseline. Every history record covers exactly its event seq. A business, persistence, or unresolved continuity failure terminates the stream, while only physical carrier loss selects automatic resumption. `SessionControlStream` is a Gateway `RemoteSnapshotStream`; every generation opens with a complete process-local baseline, so reconnect replaces queue, jobs, and projection state instead of treating transient values as durable events. Client Agent contexts provide the identity used by the independent [`fileUpload`](../../client/file-upload/README.md) service; Session objects expose lifecycle, prompt, queue, and history operations rather than file transfer. diff --git a/packages/api/session-controller/README.zh.md b/packages/api/session-controller/README.zh.md index 6fc0c92300..7bed20d3e4 100644 ---

adapter 提供 `SessionEventStream`，即绑定到一个普通 Session 或 direct subagent address 的 Gateway `RemoteJournalStream`。它在读取首个 page 前打开 follow，只发布连续的 `replace`、`prepend`、`append` 与 `settle-assistant` 变更，并通过 tail page 修复重连或 seq 缺口。向后分页有两个动词：`loadOlder()` 拉一页 50 条 message，而 `loadThrough(seq)`，即轮次跳转加载器，按 200 条 message 一页循环拉取直到窗口覆盖目标 seq，重复调用会下调共享目标，遇到无进展的页即停止，忙碌状态复用同一个 `loadingOlder` 快照位。Web adapter 显式选择接收无 cursor 的 Assistant frame：每个 opening 携带活跃 attempt 的 `startedAfterSeq`、`nextIndex` 与紧凑 stream，每个 stream member 都成为排在持久 cursor 之间的 Client-only `assistant/live-chunk` 条目。Host 会随该 baseline 捕获 follower 本地到达序号，并抑制该 cut 及之前的 buffered frame；replacement Agent 可以从 revision 一重新开始。活跃 opening 之后到达的持久 `assistant/message` 或 `assistant/attempt` 只有在其 seq 晚于 `startedAfterSeq` 且 Turn 与 Step 匹配时才会保持暂存；匹配的 end type、seq 与 index 会发布一个具名 settlement delta，删除该 attempt 的瞬态 row、加入持久条目，并保留同一步骤中更早的 retry。已知 attempt 的 revision、密集 index 或 settlement 缺口会重新打开 follow；若 controller 错过 start，则忽略 unknown-attempt frame，并正常发布其持久 settlement。Abandoned end 会发布不含持久条目的 settlement delta，使瞬态 row 立即退出。持久缺口修复 page 不携带 Assistant baseline，因此 held notification 会重新打开 follow 一次，以取得配对的 page 与 baseline。每条历史 record 只覆盖自身的 event seq。业务、persistence 或无法恢复的连续性错误会终止 stream，只有物理载体断开才触发自动恢复。`SessionControlStream` 是 Gateway `RemoteSnapshotStream`；每代都以完整的进程本地 baseline 开始，因此重连会替换 queue、jobs 和 projection 状态，而不会把瞬态值当作 durable event。Client Agent context 提供独立 [`fileUpload`](../../client/file-upload/README.zh.md) 服务使用的身份；Session 对象提供生命周期、prompt、queue 与历史操作，不提供文件传输。 diff --git a/packages/api/session-controller/package.json

The chevron opens a dense menu of the installed applications with the remembered one marked by a filled row. Availability is read once per page from the host; the last chosen application persists in the browser (`dsh.open-in-app.choice`), and a choice that is no longer installed falls back to the first available entry. A launch that finishes quickly leaves the button untouched — the dimmed busy treatment appears only after 250 ms in flight — and a failed launch shows the error tooltip and a red outline for two seconds. All copy lives in the bilingual `open-in-app` locale namespace; an application id the dictionaries cannot name is not offered. + +----- + + +## Understand the implementation + +

+Implementation internals — click to expand + +The plugin registers the split button on `conversation.session.header.utilities` through the standard slot/inject currency and registers the `open-in-app` dictionaries as one effect. A page-lifetime controller ([`src/client/controller.ts`](src/client/controller.ts)) owns the once-per-page availability read, the persisted choice snapshot store, and the launch POST; the component receives both stores through the inject `hooks` compartment, so every Session header shares one truth. Route paths and wire payload types are inlined from the host package's browser-safe `@deepseek-ai/dsh-host-open-in-app/shared` subpath. In-flight launches are guarded by a ref — repeat clicks and menu picks during a launch are ignored whole (a pick would otherwise persist a choice the gesture never opened) — and the busy/error dress is timer-driven around the `launch` promise. The node half is an empty `apply` that keeps the plugin on the host roster. + +

I After `agent/request`, `ctx.llm.prepareCall()` validates adapter-owned fields and resolves reasoning-effort and output-token defaults under the active turn signal. The loop retains that exact adapter through resolution, `request/header` logging, and dispatch. It writes a full header for the first request, a changed envelope, an explicit message-series start, a request after surface replacement, and resume; unchanged steps, retries, and ordinary later turns in the same series inherit the latest header. Before the next waterfall, the loop removes adapter-default fields so the current route resolves them again, while explicit settings persist. An unhandled route still fails with `NO_ADAPTER`. +The loop deep-freezes each derived message identity on its first request and reuses that proof only within the same agent.

Each entry declares per-platform launcher sources tried in order, and every source yields a **verified launcher** — an artifact this host actually holds — never a bare install record: + +- **macOS** checks the known application directories (`/Applications`, `~/Applications`) for the entry's bundle spellings and launches `open -a `; Xcode follows `xcode-select -p`, so Beta or renamed installs are found. No Launch Services query and no disk scan runs. +- **Windows** reads the `App Paths` registry keys, then the Uninstall records (kept only when they prove an executable on disk), then well-known install paths and the newest versioned install directory where an application uses one. GitHub Desktop resolves its versioned executable together with the packaged `cli.js` and invokes the supported `github open ` behavior without a command shell. Registry reads are batched, one `reg.exe query` per root per resolution pass. +- **Linux and Windows CLI names** resolve in-process through the composition's subprocess capability (PATH/PATHEXT stat, no shell, no `which`); Linux GUI entries whose CLI is off PATH fall back to their XDG desktop entry's verified `TryExec`/`Exec` executable, and the `xdg-open` file-manager entry appears only when the host announces a display server. + +### What to expect + +Resolution runs lazily, once per host process, on the first request that needs it; installing an application takes effect on the next restart, while an uninstalled one heals immediately — a launch that finds its executable gone re-resolves that one entry and drops it from the list when nothing proves it anymore. The icon route serves the real application icon on every platform where one is extractable: the bundle's `.icns` as a 128px PNG on macOS, the executable's associated icon as a 32px PNG on Windows, and the desktop entry's hicolor-theme icon (PNG or SVG) on Linux; a missing icon answers 404 and the browser surface renders a generic glyph. + +### The `./shared` subpath + +The route paths and wire payload types are published as the browser-safe `./shared` subpath (constants and types only, no runtime identity); the browser package inlines it into its client bundle. A route or payload change lands in `src/shared.ts` and both packages pick it up from there. + +----- + + +## Understand the implementation + +
+Implementation internals — click to expand + +The package splits into a data table and three roles. [`src/catalog.ts`](src/catalog.ts) is the compile-time table: each entry's per-platform locator chain (`fixed`, `app`, `xcode`, `cli`, `file`, `scan`, `app-paths`, `install-record`, `github-desktop`, `desktop`) plus, on Linux, the desktop-entry id owning its icon. [`src/resolver.ts`](src/resolver.ts) resolves the table against this host: one pass yields a map of catalog id to verified launch (primary and optional fallback argv plus the icon source), sharing one batched Windows-registry read; argv launches spawn detached with a credential-scrubbed environment (`scrubbedParentEnv`) plus explicit adapter entries, and keep Windows GUI processes visible unless the adapter hides a CLI process that launches the GUI separately. `shell-open` launches (the file managers) run the OS shell's open verb through `dsh-native-command`'s path opener under the same watch window, and a spawn `ENOENT` is classified as `missing` so the routes can refresh a stale entry. [`src/icons.ts`](src/icons.ts) extracts icons per platform: `plutil`/`sips` over the resolved bundle on macOS, a generated PowerShell `ExtractAssociatedIcon` script over the resolved executable on Windows (positional `-File` args keep paths out of command-line parsing), and desktop-entry/hicolor/pixmaps filesystem lookup on Linux. + +[`src/index.ts`](src/index.ts) registers the three routes on `ctx.webServer`: `GET /open-in-app/apps` (the resolution map's keys), `GET /open-in-app/icon/` (the extracted icon, cached in memory per process), and `POST /open-in-app/open` (launches the map's verified launcher directly — never a re-detection). Every route asks the composition's `connection` service for a rejection first; the complete trust story — the Host/Origin fence and browser authentication — has one home in the [`src/index.ts`](src/index.ts) module comment. On top of that fence the open route validates its body at the wire: an `application/json` media type, a 64 KiB ceiling, a resolved-available catalog id, and an absolute path naming an existing directory. Resolution and icon commands run through [`@deepseek-ai/dsh-native-command`](../../util/native-command/README.md) (argv, never a shell) under their respective deadlines; PATH names go through `ctx.subprocess.resolveExecutable()` in-process. + +

The operating system can locate known applications but cannot establish that every installed application accepts a workspace directory or which launch protocol it requires, so the package does not enumerate an unrestricted OS application list. Configurable custom handlers remain deferred; their user-supplied labels are user data rather than locale-owned product copy. +- **macOS detection is known-paths only.** A bundle renamed beyond the catalog's spellings or moved outside `/Applications` and `~/Applications` is not detected; there is no Launch Services query (a native LaunchServices/NSWorkspace lookup needs an addon the repository does not carry) and deliberately no disk scan. +- **Icon fidelity is platform-bound.** Windows icons come from `ExtractAssociatedIcon` at 32px — the most the stock .NET surface yields without a native addon — which can render slightly soft on high-DPI displays; Linux icons follow the hicolor theme and pixmaps only, not the user's active icon theme; several entries (CLI-only launchers without a desktop entry) have no icon source and keep the generic glyph. +- **New installs appear after a restart.** Resolution runs once per host process; only the uninstall direction self-heals (a missing launcher re-resolves its one entry on the spot). + + +### Dev Note + +
+Working context for maintainers — click to expand + +The promotion decisions — the host/`ui-` package split, why raw webServer routes instead of a Typert Remote, why the catalog stays compile-time fixed, the resolver redesign (verified launchers, one resolution pass, no per-click re-detection), the three-deadline configuration, and the per-platform icon strategies with their rejected alternatives — are recorded in the [promotion Agent Note](../../../.agents/notes/implemented/feature/2026-08-25-promote-open-anywhere-plugin.md). + +

The catalog remaps declared references and validates the released-v2 envelope, inherited cut, event admission, and relationships. Persistence applies full installed-current validation in its Worker before publication. `releasedV2SessionFormatCodec` creates a current row decoder and encodes current headers and events one record at a time. A successful v1 `assistant/message` must cite its complete ordered attempt. The migration removes the cited top-level chunks and obsolete message provenance, compacts the chunks without joining token boundaries, and stores the stream on that message. An unclaimed attempt becomes one log-only `assistant/attempt` at its final chunk position. Unrelated interleaved events keep their relative order. +The edge also closes the bounded legacy restart pattern in which a non-empty `next-turn` inbox insertion is followed by the next `turn/start` without the prior `turn/end`. It records that prior turn as interrupted. A legacy round-zero goal mutation becomes a `goal/change` followed by the original model-visible message with ordinary plugin attribution, so both durable goal state and historical model input survive. + The migration refuses a reference to a consumed chunk instead of redirecting it to a different semantic event. It remaps declared event provenance, surface replacements, command source events, compaction ranges and lists, and title message lists. The already model-visible `session/title-llm-request.messages` text remains byte-identical after source validation, so target validation does not reinterpret the old sequence numbers embedded in that prompt.

An incomplete final raw line is discarded. A torn final Zstandard frame contributes only its complete decoded JSONL records; a write handle truncates the torn bytes and durably rewrites those recovered records before its first new batch. Checksum, decompression, or structural failure in a complete committed frame rejects as corruption. ### Reading the logs -`open(id, 'read'|'write')` selects the highest canonical generation and publishes a current successor beside a supported historical source before returning the handle; the source remains byte-identical. The handle's `read(offset?, length?)` then serves validated contiguous slices, never a torn tail. A torn final Zstandard frame is partially decoded: complete JSONL records already flushed into it are recovered into the logical log, and the write handle's first mutation truncates current-generation torn bytes and durably rewrites the recovered records ahead of its own batch. A write open primes the handle with the validated stored prefix, and a bounded revision-keyed memo lets an immediate observe-to-resume handoff reuse that parse. `stat(id)` and `list()` select and translate only the highest generation header without reading event rows or publishing migration output; snapshots carry `sizeBytes` and a best-effort stat-derived revision for the selected file.

Current input follows the ordinary fast path. For historical input, a read open decodes and migrates the source once, validates the current logical result, and returns it without publishing a successor. A write open reuses that revision-keyed preparation when available, or performs the same preparation, then encodes a same-directory temporary file in bounded chunks, verifies it in a Worker Thread, rechecks the source revision, and publishes the current successor without overwrite before returning. The source remains byte-identical. Source drift after preparation rejects that write open without replacing the logical history already returned to readers; a later write open prepares the new revision. The backend marks decoded event graphs `shared-frozen` when it freezes them before memoization; handle reads and slices preserve that state, including empty slices. Only an unmaterialized pending log reports `detached`. `stat(id)` and `list()` select and translate only the highest generation header without reading event rows or starting migration; snapshots carry `sizeBytes` and a best-effort stat-derived revision for the selected file.

On supported Linux hosts, the original terminal argv runs directly inside a user-systemd scope, preserving the node-pty PID, session leader, controlling terminal, foreground `inputWaiting`, and readiness while the scope owns reparented or `setsid` descendants. On fallback hosts, cleanup retains exact identities from the rooted tree and observable session but cannot recover every escaped descendant. An exact Linux input wait requires a foreground thread whose fd 0 identifies the shell's controlling terminal and whose current syscall waits on that fd; if the kernel denies the syscall probe, the higher PTY backend uses its idle inference instead.

During a JavaScript-observable host exit — direct `process.exit()`, default uncaught exceptions, default unhandled rejections — a synchronous finalization force-terminates everything still owned (SIGKILL to the group, `taskkill /T /F` on Windows) without creating promises or timers. The same exit removes the private per-process spill directory when it holds no completed spill file (completed spill files are retained as full-output recovery artifacts until an external cleanup). Unhandled `SIGTERM`/`SIGINT`/`SIGHUP`, `SIGKILL`, fatal OOM, native crashes, and power loss need an external supervisor. +Normal disposal terminates every running managed range and terminal session and awaits quiescence. During a JavaScript-observable host exit — direct `process.exit()`, default uncaught exceptions, default unhandled rejections — synchronous finalization asks a Linux scope to kill its members, kills each Windows runner so its sole Job handle closes, and uses the existing PGID, `taskkill`, or captured-identity operation for fallbacks. It creates no promises or timers and does not claim quiescence. The same exit removes the private per-process spill directory when it holds no completed spill file; completed spill files remain as full-output recovery artifacts until an external cleanup. Unhandled `SIGTERM`/`SIGINT`/`SIGHUP`, `SIGKILL`, fatal OOM, native crashes, and power loss need an external supervisor. ### What can go wrong -An executable that cannot be resolved fails loud with a stable error; a spawn that never starts rejects `done`.

A daemonized descendant that leaves the tree or terminal session can outlive cleanup — see the limitations below. +An executable that cannot be resolved fails loud with a stable error. `done` rejects when spawn or provider failure prevents a direct outcome, and that rejection does not prove whether target execution began. `waitForExit()` rejects if the selected owner can no longer prove its range empty, and cleanup still attempts termination.

POSIX children spawn detached (their own process group) so the whole tree is signalled by negative group id with a direct-child fallback; Windows terminates by root pid through `taskkill /T`. Signalling, escalation, and teardown guard on tree liveness rather than direct-child settlement, so a TERM-trapping helper cannot outlive the handle unnoticed. +Each spawn selects one owner for both signalling and quiescence. Supported Linux ordinary and terminal launches use transient user-systemd scopes, while supported Windows ordinary launches use a helper-owned kill-on-close Job. macOS, older or unavailable user-systemd, and unavailable Windows native support use the existing detached process-group, `taskkill`, or terminal-session observations with one warning.

Terminal cleanup sweeps descendants by exact identity, stops the shell, re-sweeps, and verifies absence through the process table. +A spawn synchronously validates the final argv, cwd, and environment, selects containment before the user command can run, and returns a handle while target identity remains private. Linux ordinary and terminal launches use a private one-shot request whose scoped bootstrap restores the target cwd and environment, resolves the executable, clears close-on-exec on fd 0 through fd 2, and enters libc `execve()` with the original argv. Windows ordinary launches isolate runner fd 0 through fd 2, reserve fd 3 for IPC, and carry target stdio on fd 4 through fd 6; the runner resolves those CRT descriptors to OS handles, creates the target suspended, assigns it to the Job, resumes it, and closes only the carrier descriptors. `done` settles the direct command after its stdio barrier, while `waitForExit()` separately waits for the selected scope, Job, process group, or observed session to become empty. ### Safety invariants -Spill files are opened `0600` with `O_EXCL` and random names under a `0700` per-process directory, defeating symlink planting in shared temp dirs; a failed final close withholds the spill path.

These limits define when the provider is a poor fit or needs special operational care. They are current package constraints, not a general platform comparison or a task backlog. -- **Windows tree support is best-effort** — termination routes through `taskkill /PID /T /F` with all outcomes contained (absent tree, races, missing binary), and liveness falls back to the direct-child boundary. -- **Windows terminal signalling is console-wide** — SIGINT is delivered as a `\x03` Ctrl-C input write that conhost turns into a console-wide CTRL_C event; SIGTSTP and SIGHUP are rejected as unavailable; a `taskkill` without `/F` does not terminate console processes, so the teardown TERM tier is a grace wait before the `/F` escalation. -- **A daemonized terminal descendant can still escape the observable boundary** — on macOS, a child that reparents before any foreground-inspection snapshot is no longer discoverable from the PTY root; on Linux, a `setsid` child leaves both the tree and the owned terminal session; the provider adds no continuous process-table monitor. -- **In-process cleanup requires a JavaScript-observable exit** — direct `process.exit()`, default uncaught exceptions, and default unhandled rejections emit Node's synchronous `exit` event; an unhandled `SIGTERM`, `SIGINT`, or `SIGHUP`, `SIGKILL`, fatal OOM, `process.abort()`, native crashes, and power loss require an external supervisor, container init, or equivalent OS owner. +- **Native ownership has explicit host requirements** — Linux needs a readable user manager and `systemd-run --expand-environment=no`; older systemd versions use the warned PGID fallback. macOS always uses that fallback because no supported public persistent owner exists. +- **Native selection has bounded per-spawn costs** — Linux repeats the bootstrap entry, libc `execve`/`fcntl` bindings, live user manager, and literal-argv scope probe until it first succeeds; later eligible ordinary or terminal spawns recheck only the live user manager. Windows rechecks the runner entry, bindings, and current Job support before every ordinary spawn. Successful Linux deep-probe state and fallback-warning de-duplication persist for the provider lifetime. All probes finish before the user command can run, and child-process probes have a 5-second timeout. Each Linux launch creates a private request directory, checks unresolved scope establishment every 50 milliseconds, then exponentially backs off an established active scope to at most 5 seconds between queries; a Windows ordinary launch keeps one runner and IPC channel until the Job reports zero active processes. Target standard handles are inherited directly, with no named-pipe stdio or result files. +- **Windows Job inheritance has defined exclusions** — ordinary descendants inherit the Job by default, but breakaway processes are outside the guarantee. The target starts only after Job assignment; external termination of the runner in the narrow create-to-assignment interval can leave a suspended target behind. +- **Windows terminal signalling is console-wide** — SIGINT is delivered as a `\x03` Ctrl-C input write that conhost turns into a console-wide CTRL_C event; SIGTSTP and SIGHUP are rejected as unavailable; a `taskkill` without `/F` does not terminate console processes, so the teardown TERM tier is a grace wait before the `/F` escalation. Windows readiness has no exact stdin-wait tier: the prompt-marker fast path compares the shell pid as the pseudo foreground group, and silence/timing tiers cover the rest. +- **Fallback terminal ownership remains observational** — on macOS or Linux without usable user-systemd, a child that reparents before any foreground-inspection snapshot or leaves the owned terminal session can escape the process-table scan. The local provider does not add a continuous process-table monitor; supported Linux native mode instead retains these descendants through scope membership. +- **In-process cleanup requires a JavaScript-observable exit** — direct `process.exit()`, default uncaught exceptions, and default unhandled rejections emit Node's synchronous `exit` event. The default OS disposition for an unhandled `SIGTERM`, `SIGINT`, or `SIGHUP` bypasses that event; an application covers those signals only by installing a handler that performs normal disposal or calls `process.exit()`. `SIGKILL`, fatal OOM, `process.abort()`, native crashes, power loss, and any failure that cannot run JavaScript require an external supervisor, container init, or equivalent OS owner. - **The credential scrub is a name heuristic** — `*KEY*`/`*PASSWORD*`/`*SECRET*`/`*TOKEN*` only; differently named secrets (for example `*PASSPHRASE*`) pass through, and a whitelist for over-scrubbed variables is noted future work. - **Completed spill files are not deleted** — bounded full-output recovery files accumulate under the OS tmpdir until something external cleans them; the private per-process spill directory is removed at a JavaScript-observable exit only when it holds no completed spill file. diff --git a/packages/subprocess/subprocess-local/README.zh.md

Piped and inherited-stdio paths share command-line quoting, cwd, the restricted-token null-environment policy, checked return values, and handle cleanup. - **Piped process primitive** — `spawnPipedProcess()` creates anonymous stdin/stdout/stderr pipes, closes stdin immediately, returns the two read ends, and leaves process waiting and pipe draining to the caller. Every partial failure closes the handles already owned by the operation, and every Koffi out-parameter or struct allocation is freed after its Win32 lifetime. - **Inherited-stdio Job primitive** — `spawnInheritedJobProcess()` creates one kill-on-close Job, temporarily marks the current stdio handles inheritable, creates the restricted child suspended, assigns it to the Job, and then resumes its initial thread. Target code cannot run before Job assignment; controlled assignment or resume failures terminate the suspended child or close the assigned Job before releasing every owned handle. -- **Explicit settlement ownership** — `waitForProcessExit()` waits and closes the process handle. `drainPipe()` reuses one native count slot while draining, frees it, and closes the pipe read handle. The sandbox retains its existing scheduling, result composition, and caller-owned Job closure. +- **Ordinary Job runner primitive** — `CurrentTokenProcessSpawnOptions` requires a resolved `applicationName`, the complete target environment, and three runner CRT descriptors dedicated to target stdin, stdout, and stderr. `spawnCurrentTokenJobProcess()` maps those descriptors to OS handles through Node's exported `uv_get_osfhandle()`, rejects invalid results, temporarily marks the handles inheritable, and passes them through `STARTF_USESTDHANDLES`. It sends a sorted UTF-16LE environment block with `CREATE_UNICODE_ENVIRONMENT`, creates the target suspended through `CreateProcessW`, assigns it to an unnamed kill-on-close Job, and resumes it only after assignment. The original command-line argv entry remains unchanged, and the runner can close its carrier descriptors without touching Node's own standard streams. +- **Ordinary settlement operations** — `pollProcessExit()` publishes direct exit separately, while `isJobEmpty()` reads `QueryInformationJobObject(JobObjectBasicAccountingInformation)` until `ActiveProcesses` reaches zero. Checked Job termination and handle closure keep the runner as the only native owner. +- **Explicit settlement ownership** — `waitForProcessExit()` waits and closes a sandbox process handle; ordinary runner process polling, Job accounting, and checked Job termination/closure remain separate operations. `drainPipe()` reuses one native count slot while draining, frees it, and closes the pipe read handle.

Replay synthesizes the top-level envelopes in memory, while runtime persistence continues to write complete logs. Multi-session comparison restores every selected persisted or projected fixture through the current build-static Session format catalog before identity redaction and normalization, so retained v0/v1 replay input and fresh `session.v2.jsonl` writer output compare as one v2 logical Session without rewriting or renaming historical files. Expected and harvested logs use the same strict restoration path; source filenames cannot alter format validation. Versionless protocol-adapter unit fixtures remain outside the released Session format corpus. Current v2 fixtures use one row per event; retained v0/v1 fixtures may use canonical packed rows. The [temporary repository migrator](../../../scripts/migrate-packed-session-fixtures.ts) (`pnpm run migrate:packed-session-fixtures`) rewrites older historical layouts, and its [removal proposal](../../../.agents/notes/proposed/process/2026-07-26-remove-packed-session-fixture-migrator.md) owns its deletion. +Known snapshot spill paths normalize to stable locator tokens, including paths quoted inside JSON omission notices with JSON-escaped Windows separators. Refresh extraction preserves the matched serialized path spelling for literal replacement. Normalization changes only the locator: saved byte lengths and omission counts remain comparison evidence. + ### Record, replay, and refresh `pnpm run test:snapshot:record` calls the live LLM and writes the harvested current generation under its canonical versioned filename. Record and refresh never rename or delete a completed generation, including generations of a child role absent from a later run; reviewed source-tree curation removes a predecessor only after the same role has a verified current replacement. Scenarios with an explicit `sessionFormat` remain read-only in record mode. `pnpm run test:snapshot:refresh` stays keyless, runs the selected highest replay input, and writes stdout, owned prompt and tool-schema sidecars, and a fresh current-generation comparable Session output unless the manifest retains a historical generation. Each composition owner keeps its replay patch beside its live patch; top-level `snapshots/` owns Session-driven scenarios, while other expected outputs stay beside their owning package.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

That EPERM is the documented boundary: do not retry the command another way — escalate the exact command once or restructure it to avoid capturing output. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.
