merge: integrate origin/main and re-advance the contract to 1.101.0

Main moved the public contract to 1.100.0 after this head, so the
'API contract version uniqueness (latest main)' status would fail with
'1.99.0 regresses below main's 1.100.0'. Resolve the document conflict by
keeping main's description plus this branch's retained-tombstone
sentence, and advance the version past main's. The design doc's contract
line follows the same number.

+keeps per-worktree config separately, and `extensions.worktreeConfig` is
+what makes git read it at all. Because `extensions.` is itself a KEPT

+still plant `core.hooksPath` while the sweep below reports itself clean —
+so the file and the matching local `extensions.worktreeConfig` key both
+go before the sweep.
+
+The hooks path is then resolved with `GIT_CONFIG_GLOBAL=/dev/null
+GIT_CONFIG_SYSTEM=/dev/null`, i.e. from the repository only, and only
+after the allowlist sweep. Both properties are load-bearing: resolving
+before the sweep would let a config a global override supplied decide the
+path the containment guard validates, and a prior job's
+`--worktree core.hooksPath=/` would survive the local sweep untouched,
+leave the hooks path outside the git dir, make the guard refuse the

+# Mod prompt.submit in headless runs
+
+Design: [docs/design/2026-10-30-mod-prompt-submit.md](../../docs/design/2026-10-30-mod-prompt-submit.md).
+
+## Setup
+
+- Build the CLI and bundle it: `npm run build && npm run bundle`.
+- Use an isolated `HOME` whose `.qwen/settings.json` sets `experimental.mods` to `true`, selects `openai` auth and points `OPENAI_BASE_URL` at a loopback OpenAI-compatible fixture that answers `OK` and records every request.
+- Install a guard Mod with `qwen extensions install ./guard-mod --consent`. Its `hooks/register.js`:
+
+```javascript
+export function register(on) {
+  on('prompt.submit', async ($, e, next) => {
+    $.ui.log('submit:' + JSON.stringify(e));
+    if (/AKIA[0-9A-Z]{16}/.test(e.text)) return { drop: 'the prompt holds an AWS access key' };
+    if (e.text === 'boom') throw new Error('guard broke');
+    if (e.text === 'mine') return { text: 'answered without next' };
+    const entered = await next({
+      ...e,
+      text: e.text.replace(/\bprod\b/g, 'production'),
+      context: [
+        ...(e.context ?? []),
+        e.text.startsWith('note') ? 'Mod note: ' + e.text : 'Mod context: <be brief>',
+      ],
+    });
+    $.ui.log('entered:' + JSON.stringify(entered));
+    return entered;
+  }).catch(($, e, next) => (next.called ? next(e) : { drop: 'the guard failed' }));
+  on('turn.start', ($, e, next) => {
+    $.ui.log('turn.start:' + e.text);
+    return next(e);
+  });
+}
+```
+
+## Test groups
+
+### Rewrite and context
+
+- `qwen -p 'deploy prod now' --output-format json`: exit 0. The model reads `deploy production now` followed by the hidden block `Mod context: &lt;be brief&gt;`. `turn.start` hears `deploy production now`. The transcript user record has `displayText: "deploy production now"` and the block as `hookContext`.
+
+### Drop
+
+- `qwen -p 'key AKIAABCDEFGHIJKLMNOP' --output-format json`: exit 1, no model request, error result `Prompt dropped by a hook: the prompt holds an AWS access key`.
+- The same prompt in text output: exit 1, the reason on stderr.
+- `-p boom`, where the guard throws and its `.catch` drops: exit 1, no model request, `Prompt dropped by a hook: the guard failed`.
+- `-p mine`, where the guard answers without `next`: exit 1, no model request, `Prompt not submitted: a hook answered without passing the prompt on`.
+
+### stream-json
+
+- A message holding a key, then `ship prod`: the first message ends with the error result, the session goes on, and the second reaches the model as `ship production`.
+- A message `[text 'ship prod', image block]`: the model reads `ship production` with the serialized image block after it, and the transcript `displayText` keeps the block after the rewritten text, the same shape it has without a rewrite.
+
+### Context sent once per context
+
+Add a settings `UserPromptSubmit` command hook that prints `settings-note`, then send `note one`, `note two`, `note two` in one stream-json session:
+
+- `note one`: block `Mod note: note one\n\nsettings-note`.
+- `note two`: block `Mod note: note two` only; the unchanged `settings-note` is not sent again.
+- `note two` again: no block; both contexts are already in the conversation.
+
+## Results (2026-11-02, branch head after merging main)
+
+Built CLI, real fixture server, all groups above pass:
+
+| Run | Result |
+| --- | --- |
+| rewrite (json) | exit 0, model reads `deploy production now` + context block, transcript `displayText` rewritten |
+| drop (json / text) | exit 1, 0 model requests, drop reason as error result / on stderr |
+| guard throws, `.catch` drops | exit 1, 0 model requests, `the guard failed` |
+| answer without `next` | exit 1, 0 model requests, `Prompt not submitted: ...` |
+| stream-json drop then rewrite | first message error, second sent as `ship production` |
+| stream-json rewrite with an image block | transcript `displayText` = `ship production\n{"type":"image",...}` |
+| context sent once per context | blocks `["Mod note: note one\n\nsettings-note"]`, `["Mod note: note two"]`, `[]` |
+
+## Baseline
+
+`main` at `619a601b39`, bundled locally, skips every `prompt.submit` hook at startup (`Hooks for unsupported events will not run: prompt.submit`): the key prompts reach the model with exit 0, and `turn.start` hears the original text. The global `qwen` 0.25.1 on this machine is a standalone binary, which the fixture driver (it starts the CLI with `node`) cannot run, so the baseline comes from the `main` bundle.

+- `no_action`: evidence is ambiguous, unsafe, incomplete, or does not justify another action. This still records a tracking marker and a short manual-review notice on the PR.
 
 When (and ONLY when) the `rerun` cause is a nondeterministic **TEST** — a specific named test that timed out, is order-dependent, or depends on wall-clock/randomness — also identify it so the loop can open a deflake fix. Add a `flakyTest` object with the exact failing `file` (repo-relative path) and `name` (the full test title, e.g. `describe › it`) taken verbatim from the log. Emit `flakyTest` ONLY for genuine test nondeterminism, NEVER for infra flakiness (ENOSPC, network, runner death, dependency download) — those get a plain `rerun` with no `flakyTest`. If the log does not name a specific test, omit `flakyTest`. Keep `file` and `name` each at most 200 characters (take the test title verbatim; if a nested `describe › it` chain is longer, keep the most specific tail). A malformed or over-length `flakyTest` is simply ignored — the rerun still happens — so never drop a valid rerun over it.

+directory (the workflow provides it in CI):
+
+```bash
+# Fresh per run: a reused directory would append to a previous run's
+# actions. CI provides a per-run directory via QWEN_TRIAGE_DRAFT_DIR.
+DRAFT_DIR="${QWEN_TRIAGE_DRAFT_DIR:-$(mktemp -d /tmp/triage-drafts-XXXXXX)}"
+mkdir -p "$DRAFT_DIR/bodies"
+```
+
+Write each body as a file under `$DRAFT_DIR/bodies/`, then append one JSON
+action per line to `$DRAFT_DIR/actions.jsonl` (use `jq -cn` so names and
+labels are escaped safely). Actions execute in file order:

+Rules the publisher enforces (fail-closed; do not rely on leniency):
+
+- Comment bodies must start with the exact marker line
+  `<!-- qwen-triage <marker> -->`; markers are limited to `stage=1`,
+  `stage=2`, `stage=3`, `stage=1-pre`, `stage=1b`.
+- Bodies are capped at 65,536 characters — rejected, not truncated.
+- `APPROVE` requires the full reviewed `commit_id`; the publisher skips it
+  as stale if the head moved, and suppresses duplicate approvals and
+  duplicate `CHANGES_REQUESTED` reviews.
+- Labels must already exist; the publisher never creates one.
+- Comment upserts match bot-authored comments whose body starts with the
+  marker — a quoted marker in someone else's comment is never touched.
+
+Two modes:
+
+- **CI** (`QWEN_TRIAGE_PUBLISH=workflow`): draft only, then stop. The
+  workflow's `publish-triage` job validates and executes the drafts with the
+  bot PAT. Never attempt GitHub writes yourself — your token is read-only,
+  and the CI denylist blocks running the publisher.
+- **Local** (no `QWEN_TRIAGE_PUBLISH`): after the final stage, run the same
+  publisher with your own `gh` auth:
+
+  ```bash
+  node .github/scripts/triage-publish.mjs \
+    --drafts "$DRAFT_DIR" --repo "$REPO" --number "${PR_NUMBER:-$ISSUE_NUMBER}"
+  ```
+

 **⛔ Approval guardrail — check this BEFORE approving.** A cross-repository (fork) `refactor` PR must never be auto-approved: refactors touch structure broadly and a fork author is not a trusted committer, so these always need a human maintainer's eye (this rule exists because such a PR was wrongly auto-approved and merged).

Approving while the unit suite is still running would attest to a result that does not exist yet; that gap is exactly what the deferred path closes.

+## Local container recipe (Docker + model proxy)
+
+The boundary and the model credential are separate problems: the container
+isolates PR code, and a host-side proxy keeps the real model key out of the
+container. `scripts/verify-pr-model-proxy.mjs` is that proxy — the same relay
+rules as the CI lane's inline one (only `POST /chat/completions`, a per-run
+bearer token, a per-chunk idle watchdog), plus hop-by-hop request header
+stripping. The CI lane deliberately keeps its own inline copy.
+
+Two checkouts are involved, and they are not interchangeable:
+
+- `<trusted-clone>` — a checkout of `main` (or another trusted revision) that
+  the PR cannot write. Every script the round runs on the host or inside the
+  boundary comes from here.
+- `<pr-clone>` — a **standalone** clone checked out at the PR head. The round
+  runs here, so its `.git` lives inside the tree; a linked worktree's gitfile
+  points at an absolute host path the container cannot see. Prepare is given
+  this tree as its cwd and refuses any other HEAD.
+
+Never execute a script from `<pr-clone>`: the proxy, the prepare preflight,
+the credential scan, the isolation gate, the publish guard and the checker all
+come from `<trusted-clone>`. A PR can rewrite a script in its own tree, and
+these steps run with the real key, the maintainer's `gh` access, or the
+authority to certify the round.

+
+   prepare resolves the tree from its cwd, so the trusted copy runs with
+   `cwd=<pr-clone>` and still verifies that this tree is the PR head. The
+   artifact directory's `context.json` carries only the four coordinates; the
+   round reads the full gh snapshot (title, body, author, commits) from
+   `$QWEN_VERIFY_CONTEXT`, prepare's review snapshot lands beside it as
+   `review-threads.json` (absent when its fetch failed, as in CI), and the
+   newest substantive verify comment lands
+   beside it as `previous-report.md` so a follow-up round keeps its
+   carried-forward findings. That file exists only when a report was actually
+   found — its presence is the follow-up trigger, so an empty file would
+   misclassify every first round — and the selector matches the first
+   paragraph of a bot's or your own report, not a reply quoting `Verdict:`.
+   The `.qwen` extraction starts from an empty directory, so a file the base
+   deleted or renamed cannot survive from an earlier round. The host copy is
+   also what pins the expected head after the round, because PR code can
+   rewrite anything inside `<pr-clone>` — including `.git/config`. After a
+   round the clone is PR-controlled: re-clone before another round instead of
+   trusting it again, and note that prepare's host-side git commands disable
+   `core.fsmonitor`, hooks, credential helpers and `core.excludesFile`, and
+   empty every locally defined clean/smudge/process filter — the enumeration
+   follows `include.path`, reads key names NUL-framed and re-validated (a
+   filter value with a newline must not forge overrides), covers
+   `.git/config.worktree` when `extensions.worktreeConfig` is set, and the
+   fixed hardening is applied last so nothing outranks it. A filter name
+   containing `=` is refused outright: git splits `-c` at the first `=`, so
+   such a name cannot be safely disabled by an override. Prepare also
+   refuses a `.git/info/exclude` with active patterns: no `-c` can neutralize
+   that file, and a fresh clone has only the commented default.
+   Mounting the base commit's `.qwen` over the tree (step 3) keeps the
+   round's instructions and project settings out of PR control, as the CI
+   lane's base-pin does; the root `AGENTS.md`/`QWEN.md` are not covered and
+   still come from the PR clone.

+
+   Bind the Docker bridge address, not `127.0.0.1` — a container cannot reach
+   the host's loopback. On Docker Desktop (macOS/Windows) the bridge lives
+   inside the VM and has no host-bindable address: this recipe is tested on a
+   Linux host, and on Desktop you must bind an address the VM can reach and
+   dial that same address from the container. The bearer check stays
+   mandatory: the port is visible to every container on the bridge. Keep the
+   proxy running for the whole round and stop it at the end — it holds the
+   real key. The background process truncates `proxy.json` before it prints,
+   so the loop waits for a complete line with a token; stderr goes to a
+   separate `proxy.err`, because one diagnostic line folded into the JSON
+   file would break every parse of it. The nonce is checked at the origin
+   because the printed `baseUrl` carries the upstream path prefix. The key is
+   unset as soon as the proxy owns its copy, so later diagnostics cannot leak
+   it, and the token stays in the file rather than this shell.
+
+3. **Start the boundary as a named, detached container** so every later step
+   can be issued without a TTY. Each step is its own shell: the token is
+   re-derived from `proxy.json` here, not inherited from step 2.
+
+   ```bash
+   export QWEN_VERIFY_PROXY_TOKEN="$(node -e 'const fs=require("node:fs"); console.log(JSON.parse(fs.readFileSync(process.argv[1], "utf8")).token)' ~/.cache/qwen-verify/pr<n>/proxy.json)"

+     -e QWEN_VERIFY_PROXY_TOKEN \
+     -w /work node:22-bookworm sleep infinity
+   ```
+
+   No host `HOME`, no `gh` token, no `SANDBOX_MOUNTS`. The token travels as
+   `QWEN_VERIFY_PROXY_TOKEN`, **not** `OPENAI_API_KEY`: `--require-isolation`
+   refuses any non-empty `OPENAI_API_KEY` (it cannot tell a proxy token from
+   a real key), and this name is not a credential signal. Running as the host
+   uid keeps files written into the mounted tree — including the round's
+   artifacts — owned by the maintainer, not root.
+
+4. **Point the provider at the proxy** in the container's fresh
+   `$HOME/.qwen/settings.json`; the runtime reads the credential from
+   `envKey`, so no `OPENAI_API_KEY` is needed:
+
+   ```bash
+   docker exec -i qwen-verify-<n> bash -lc 'mkdir -p "$HOME/.qwen" && cat > "$HOME/.qwen/settings.json"' <<'JSON'
+   {
+     "security": { "auth": { "selectedType": "openai" } },
+     "model": { "name": "<model-id>" },
+     "modelProviders": {
+       "openai": [
+         {
+           "id": "<model-id>",
+           "envKey": "QWEN_VERIFY_PROXY_TOKEN",
+           "baseUrl": "<baseUrl from proxy.json>"
+         }
+       ]
+     }
+   }
+   JSON
+   ```
+
+5. **Attest inside, after trusted checks — never on the `docker run` line.**
+   The gate only sees known credential names and home paths, and gitignored
+   files are invisible to its clean-tree check, so scan for project
+   credential files and run the gate from the trusted copies first:
+
+   ```bash
+   docker exec -i qwen-verify-<n> bash -lc '
+     node /trusted-scripts/verify-pr-credential-scan.mjs /work || exit 1
+     export QWEN_VERIFY_CREDENTIAL_FREE=1
+     node /trusted-scripts/verify-pr-prepare.mjs --require-isolation
+   '
+   ```
+
+   The scan names credential-shaped ignored files (nested ones included, but
+   not public keys; the private-key families cover RSA, Ed25519, ECDSA and
+   DSA) and credential-bearing git config. It inspects every local config
+   value rather than a list of keys — any value can hide a token URL,
+   `http.proxy` included — and refuses http(s) userinfo (a token used as the
+   username counts; the bare `git@` account name, in any spelling, carries
+   no secret and stays benign, like `ssh://git@`) plus `Authorization` /
+   `Proxy-Authorization` header values. The URL-bearing key families are
+   judged too: `url.*.insteadOf` / `url.*.pushInsteadOf` rewrites and
+   `http.<url>.*` sections. The config enumeration follows `include.path`
+   and covers the enabled `.git/config.worktree` scope, so a credential in
+   an included worktree file or the worktree config is refused too. The
+   file is optional: absent means an empty scope, while an unreadable or
+   malformed one still refuses. It leaves installed dependencies and build
+   output alone — a vendored git dependency under `node_modules`/`dist` is
+   excluded, not refused — and refuses a nested git repository outright on
+   every surface (ignored clone, untracked clone, populated submodule): git
+   does not descend into it, so a credential file inside one would
+   otherwise pass silently. The abort is structural (`|| exit 1`), not a
+   side effect of `set -e`. Exit 4 means this is not a boundary: stop and
+   run nothing else.
+
+6. **Run the round inside**, installing the CLI into the fresh home because
+   the container is not root. Each `docker exec` is a new shell, so the
+   attestation is passed to the shell that starts the round; it stays off the
+   `docker run` line. The round's engine is the released CLI, and the PR
+   clone supplies the code under test; the round's instructions come from the
+   base commit's `.qwen` mounted in step 3, not from the PR. Root
+   `AGENTS.md`/`QWEN.md` do come from the PR clone — when the diff touches
+   them, treat the round's context as PR-influenced:
+
+   ```bash
+   docker exec -i -e QWEN_VERIFY_CREDENTIAL_FREE=1 qwen-verify-<n> bash -lc '
+     set -e
+     export PATH="$HOME/.local/bin:$PATH"
+     npm install -g --prefix "$HOME/.local" @qwen-code/qwen-code
+     qwen --auth-type openai --approval-mode yolo \
+       --prompt "/verify-pr <n> --repo <owner>/<repo>"
+   '
+   ```
+
+   To run the tree's own CLI instead, replace the install line with a build
+   and a local install after resolving the dependencies:
+
+   ```bash
+   corepack pnpm install --frozen-lockfile
+   npm run build && npm run bundle
+   npm install -g --prefix "$HOME/.local" /work
+   ```
+
+7. **After the round, check and clean up from the host.** The checker and its
+   expected head both come from outside the round tree:
+
+   ```bash
+   node <trusted-clone>/scripts/verify-pr-check.mjs \
+     --context ~/.cache/qwen-verify/pr<n>/pr.json <round-dir>
+   docker rm -f qwen-verify-<n>

+   rm -f ~/.cache/qwen-verify/pr<n>/proxy.json ~/.cache/qwen-verify/pr<n>/proxy.err ~/.cache/qwen-verify/pr<n>/proxy.pid
+   unset QWEN_VERIFY_PROXY_TOKEN
+   ```
+
+   `<round-dir>` is the artifact directory prepare printed —
+   `<pr-clone>/tmp/pr<n>-verify-<ts>`, never `tmp/verify-context`, which also
+   matches a loose `*verify*` glob. `<host snapshot>` throughout this recipe

+#### Bug Fixes
+
+- Pins the RHEL 10 EPEL bootstrap RPM and makes desktop smoke teardown treat Linux zombie processes as stopped while still reporting live daemon failures. ([#16154](https://github.com/QwenLM/qwen-code/pull/16154)) by @yiliang114
+- Compacts live ACP tool-result displays for session replay, so large file edit results show a saved-session preview instead of full old and new contents. ([#16172](https://github.com/QwenLM/qwen-code/pull/16172)) by @wenshao
+- Fixes PR review endpoint routing by selecting the cohort before the model and reports the final bucket, cohort, model, and endpoint hostname. ([#16151](https://github.com/QwenLM/qwen-code/pull/16151)) by @yiliang114
+- fix(serve): keep record_artifact guidance out of Managed Runtime worker results ([#16148](https://github.com/QwenLM/qwen-code/pull/16148)) by @wenshao
+- Binds web-shell config synchronization to the current attachment so config writes made by the first prompt are no longer silently discarded. ([#16170](https://github.com/QwenLM/qwen-code/pull/16170)) by @wenshao
+- Fixes tool-choice failures on Claude Opus 5.5, Sonnet 5.5, Fable 5.1, and Mythos 5.1 by avoiding unsupported forced tool selection. ([#15558](https://github.com/QwenLM/qwen-code/pull/15558)) by @Adkid-Zephyr
+- Fixes Web Shell pasting so a single copied image with an HTTP(S) URL attaches the image, while unavailable file pastes show a warning. ([#16179](https://github.com/QwenLM/qwen-code/pull/16179)) by @ytahdn
+- Requires explicit folder trust before repository-supplied hooks, permission grants, and project language servers can run, improving safety for untrusted projects. ([#16182](https://github.com/QwenLM/qwen-code/pull/16182)) by @yiliang114
+- Anthropic-compatible requests now honor the configured transport timeout and dispatcher, preventing premature request aborts when a longer API timeout is set. ([#16193](https://github.com/QwenLM/qwen-code/pull/16193)) by @yiliang114
+- Remote-access error handling now hides internal error details from callers and fixes several reviewed reliability and security defects. ([#16199](https://github.com/QwenLM/qwen-code/pull/16199)) by @yiliang114
+- On touch devices, navigation now keeps focus on the chat pane instead of opening the composer keyboard, while desktop focus behavior remains unchanged. ([#16198](https://github.com/QwenLM/qwen-code/pull/16198)) by @ytahdn

+- ACP bridge operations that finish alongside long-lived session or channel events now clean up their results instead of retaining them. ([#15347](https://github.com/QwenLM/qwen-code/pull/15347)) by @Sumire-no-kai
+- Ordinary workspace execution, member release, and file rewind no longer take the tenant-wide placement lock, reducing cross-workspace blocking. ([#16205](https://github.com/QwenLM/qwen-code/pull/16205)) by @doudouOUC
+- Embedded-webview bundle guard failures now show a readable assertion naming the forbidden marker instead of crashing on a large diff. ([#16210](https://github.com/QwenLM/qwen-code/pull/16210)) by @yiliang114
+- Project hooks in .qwen/settings.json now require explicit folder or workspace trust in interactive sessions and show a warning when withheld. ([#16196](https://github.com/QwenLM/qwen-code/pull/16196)) by @yiliang114
+- OpenRouter IDs with :exacto now keep the base model name, so qwen/qwen3-coder:exacto gets its 262,144-token window instead of 200K. ([#16165](https://github.com/QwenLM/qwen-code/pull/16165)) by @Shizoqua
+- Shell permission analysis now treats grep -n and grep --line-number as flags, so grep file reads are still checked. ([#14383](https://github.com/QwenLM/qwen-code/pull/14383)) by @kabishou11
+- Monitor and workflow completion notifications are attributed to the registering turn, letting active-turn results reach the next model request sooner. ([#16177](https://github.com/QwenLM/qwen-code/pull/16177)) by @yiliang114
+- Makes CI sandbox image builds more reliable on hosts with slow default Debian mirrors by switching to a faster mirror only when speed checks require it. ([#16218](https://github.com/QwenLM/qwen-code/pull/16218)) by @yiliang114
+- Scopes GitHub, GitLab, and DWS polling cursors to each workspace, preserving existing positions on upgrade while storing channel state with stricter permissions. ([#16231](https://github.com/QwenLM/qwen-code/pull/16231)) by @wenshao
+- Improves CI apt mirror selection by preferring the VPC intranet mirror and switching when a candidate is fast enough, even if the default mirror seems acceptable. ([#16260](https://github.com/QwenLM/qwen-code/pull/16260)) by @yiliang114
+- Fixes RHEL 10 desktop smoke tests by running them headless without requiring Xvfb. ([#16211](https://github.com/QwenLM/qwen-code/pull/16211)) by @yiliang114
+
+#### Performance
+

+- Managed Agent turn submission admission and migration preparation avoid the tenant placement lock where safe, reducing wait time without changing request outcomes. ([#16223](https://github.com/QwenLM/qwen-code/pull/16223)) by @doudouOUC
+- Standalone Harness admission, recovery, cleanup, and Hook admission checks no longer take the tenant placement lock, improving Managed Agent performance with unchanged verdicts. ([#16221](https://github.com/QwenLM/qwen-code/pull/16221)) by @doudouOUC
+- Speeds up local Workspace file reads, uploads, and status checks by reusing CLI capability probes when local CLI identity is unchanged. ([#16229](https://github.com/QwenLM/qwen-code/pull/16229)) by @doudouOUC
+- Improves Session responsiveness by reducing locking for common commands such as model changes, approvals, context compression, task cancel, and renames. ([#16225](https://github.com/QwenLM/qwen-code/pull/16225)) by @doudouOUC
+
+#### Documentation
+
+- Release documentation now explains why publish can remain queued on GitHub-hosted runners and why those steps are not moved to ECS pools. ([#16194](https://github.com/QwenLM/qwen-code/pull/16194)) by @yiliang114
+- Managed Agent structure-review documentation now reflects the completed store decomposition and current audit status. ([#16230](https://github.com/QwenLM/qwen-code/pull/16230)) by @wenshao
+

+## Daemon Mode
+
+Run Qwen Code as a long-lived service when you want browser, editor, SDK, and automation clients to share agent sessions without each starting a separate process. The daemon provides the built-in Web Shell and an HTTP + SSE API, supports multiple workspaces, and lets clients reconnect to active sessions.
+
+Start it in the foreground and open the Web Shell:
+
+```bash
+qwen serve --open
+```
+
+The default address is `http://127.0.0.1:4170`. To run and manage it in the background instead:
+
+```bash
+qwen daemon start
+qwen daemon status
+qwen daemon logs -f
+qwen daemon stop
+```
+
+By default, the daemon listens on loopback without bearer authentication; any local process that can reach it can use the full API, including code execution. On shared or untrusted hosts, set `QWEN_SERVER_TOKEN` and use `--require-auth`. See the [Daemon guide](./docs/users/qwen-serve.md) for workspaces, authentication, remote access, and the API.
+
 ## Capabilities
 
 If you know Claude Code, you already know Qwen Code — and then some. We've put significant effort into [bringing Qwen Code to feature parity with Claude Code](https://github.com/wenshao/codeagents/blob/main/docs/comparison/qwen-code-improvement-report.md), improving both breadth and reliability across the board.

 ## Goal
 
 Make GitHub-channel replies safe to publish automatically and traceable after the fact. The channel publishes only the agent's final response through the adapter; intermediate reasoning, tool output, and streaming chunks never become GitHub comments.
 
 ## Contract
 
-- The GitHub adapter disables block streaming, so each accepted inbound event produces at most one final response-delivery attempt.
+- The GitHub adapter disables block streaming, so each accepted inbound event produces at most one final response to deliver.
 - Final delivery uses the active prompt's issue/PR thread rather than a potentially stale shared-session target.
 - Channel instructions tell the agent not to use `gh` or the GitHub API to create comments or reviews. The adapter owns public delivery.
 - A final response whose trimmed content is only the `<no-reply/>` sentinel is intentionally suppressed. Whitespace, case, a space before `/>`, and a single wrapping code fence are normalized; any other content is published unchanged.
 - Suppression and publication are recorded in a local append-only JSONL audit file at `~/.qwen/channels/<workspace-scope>/<channel>-<name-hash>-github-audit.jsonl`. Records contain time, channel, session, source message, thread, outcome, GitHub comment identity/URL when present, and a SHA-256 plus character count of the reply. They never contain reply text, credentials, or a GitHub token.
-- Audit writes are best effort. An audit failure is logged without changing the publication result. An ambiguous GitHub API failure remains a delivery failure and is not retried; definite no-write responses are written to a private pending-delivery file and retried on the next channel start.
+- Audit writes are best effort. An audit failure is logged without changing the publication result. An ambiguous GitHub API failure remains a delivery failure and is not retried. A definite no-write response — GitHub's rate limiter refusing the comment with a 403 or 429 that carries a numeric `x-ratelimit-remaining` and shows the budget exhausted, sends `retry-after`, or names a secondary rate limit in its message — is retried in process and, if GitHub still refuses it, written to a private pending-delivery file and retried on the next channel start. A rate-limit answer without that header is ambiguous.

+# GitHub Channel 发布契约
+
+[English](2026-07-29-github-channel-publication-contract.md) | [简体中文](2026-07-29-github-channel-publication-contract.zh-CN.md)
+
+## 目标
+
+让 GitHub channel 的回复可以安全地自动发布，并在事后可追溯。channel 只通过适配器发布 agent 的最终回复；中间推理、工具输出和流式分块永远不会变成 GitHub 评论。
+
+## 契约
+
+- GitHub 适配器关闭块流式输出，因此每个被接受的入站事件至多产生一个待投递的最终回复。
+- 最终投递使用当前 prompt 所在的 issue/PR 线程，而不是可能已过期的共享会话目标。
+- channel 指令要求 agent 不得用 `gh` 或 GitHub API 创建评论或 review，公开投递由适配器负责。
+- 去除首尾空白后只剩 `<no-reply/>` 哨兵的最终回复会被有意抑制。空白、大小写、`/>` 前的空格以及单层包裹的代码围栏会被规范化；其它内容原样发布。
+- 抑制和发布都记录在本地只追加的 JSONL 审计文件 `~/.qwen/channels/<workspace-scope>/<channel>-<name-hash>-github-audit.jsonl` 中。记录包含时间、channel、会话、来源消息、线程、结果、存在时的 GitHub 评论标识/URL，以及回复的 SHA-256 和字符数。记录中绝不包含回复正文、凭据或 GitHub token。
+- 审计写入是尽力而为的。审计失败只记日志，不改变发布结果。歧义的 GitHub API 失败仍算投递失败，不会重试。确定未写入的响应——GitHub 的限流器以 403 或 429 拒绝评论，响应带有数值形式的 `x-ratelimit-remaining`，并且配额已耗尽、带有 `retry-after`，或报错文案写明是二级限流——会先在进程内重试；如果 GitHub 仍然拒绝，就写入私有的待发投递文件，并在下次 channel 启动时重试。缺少该头的限流答复按歧义处理。
+
+## 流程
+
+1. GitHub 适配器把被接受的事件派发进 `ChannelBase`。
+2. 当前 prompt 在最终投递结束前一直保留入站消息和 issue/PR 线程。
+3. agent 返回一个最终回复。
+4. 适配器要么抑制精确匹配的哨兵，要么创建一条 issue 评论。
+5. 适配器追加一条发布审计记录。任务的终态生命周期仍由 `ChannelBase` 负责。
+6. 如果最终投递遇到确定未写入的响应，适配器会再尝试两次：`retry-after` 是正的秒数时按它等待；否则在配额耗尽时等到配额重置；再否则先等一分钟、再等两分钟（重置时间看起来已经过去时也是如此）。其中某次尝试拿到歧义答复时，按普通歧义失败处理，结束尝试且不留待发记录。如果 GitHub 仍然拒绝，或 channel 在等待期间停止，适配器会把最终文本以私有文件权限存入 `~/.qwen/channels/<workspace-scope>/<channel>-<name-hash>-github-pending-deliveries.json`，重启后重试投递，不重新运行 agent。启动时的这轮重试遇到 GitHub 仍在限流的第一条待发回复即停止发送，后面的回复留到下次启动；答复为确定未写入时，这一条也一并保留；审计中已记录为 posted 的回复会被丢弃。
+
+## 非目标
+
+- 不重试歧义的发布失败，不创建状态评论，也不启用流式回复。这些属于 issue #8012 的其它部分。
+- 禁止 agent 直接用 `gh`/API 发布的指令只是对 agent 的操作边界，不是沙箱强制。工具级 GitHub 写入限制的强制执行属于运行时权限模型。
+- 待发投递的保留策略，包括最大尝试次数、最长保留时间、大小上限、过期回复处理和遗留临时文件清理，另由 #8142 跟踪。
+
+## 验证
+
+GitHub 适配器的针对性测试覆盖哨兵抑制、正常的最终评论投递、不含回复正文的审计字段，以及不阻塞的审计写入失败。已有的路由和投递测试保持不变。另有适配器测试覆盖哪些拒绝算作确定未写入、进程内等待及等待期间的停止，以及启动时对待发投递的那轮重试。

When the record write fails (a lock held past its wait, an unreadable or full disk) and no earlier record for the same connection stands, it answers `saved: false` with `saveError`: the join is live for this run, but the clients tell the operator it will not return after a restart, because the restore loop only reconnects records it finds saved.

@@ -42,7 +42,7 @@ The facts below are from this slice's base, `main` at `e92b60a282`.
 10. **Timezones resolve at admission on a pinned database.** The H6a contract checks the name's shape only; the control plane refuses a definition whose zone the host tz database does not resolve (`400 automation_timezone_unknown`), and the scanner parks a definition whose zone stops resolving (`blocked_reason`) rather than firing it on a guess.
 11. **Definitions are Session-creator mutations, answered synchronously with `202`.** `POST /v1/agent-automations` creates a definition for a Workspace-bound Session the caller created (the same authorization as later Turns and cwd changes); `POST /v1/agent-automations/{automationId}` revises it; `DELETE` retires it (the chain ends `cancelled` and freezes); `POST /v1/agent-automations/{automationId}/runs` fires a manual run. Each takes an `Idempotency-Key`, is relayed to the Harness synchronously, answers `202` with the resource, and replays by key through the control plane's command ledger with `X-Qwen-Idempotent-Replay: true`; a different body under the same key answers `409 idempotency_conflict`. The reference design's `202 + operationId` is honoured as D8a honours it: the answer is the committed resource, and the control plane never holds a half-committed operation, because the Harness answers only after the journal did.
 12. **Three ledgers, one authority.** The journal's `schedule` and `automation_run` chains are the only business facts. The control plane keeps three rebuildable indexes: the definition row (the scanner's view of the latest revision, refreshed from the record when its mirrored revision lags, plus the lease and watermark), the occurrence row (one per decision, keyed by `occurrenceKey`, carrying the derived run id, the trigger, the outcome and its reason), and the command row (public idempotency). None holds a second copy of a journal fact that the journal does not settle.
-13. **Enablement is mode-scoped and deployment-gated.** `schedule` and `automation_run` join `MANAGED_SESSION_ENABLED_DOMAINS`; a new gate beside it, `MANAGED_SESSION_ENABLED_SCHEDULE_SESSION_MODES = ['persistent']`, is checked by the authority on every `schedule` revision (the mode is not a fixed key of the chain, so checking only the first would let a later revision name a mode no first revision may open), and a run inherits it through decision 3. The control plane's scanner and the mutation routes stay inert unless `qwen.managed-agent.automation.enabled` is true (default false); the read routes always answer. The server-first order holds: the Java store has validated both bodies since H6a and gains the cross-record checks here.
+13. **Enablement is mode-scoped and deployment-gated.** `schedule` and `automation_run` join `MANAGED_SESSION_ENABLED_DOMAINS`; a new gate beside it, `MANAGED_SESSION_ENABLED_SCHEDULE_SESSION_MODES = ['persistent']`, is checked by the authority on every `schedule` revision (the mode is not a fixed key of the chain, so checking only the first would let a later revision name a mode no first revision may open), and a run inherits it through decision 3. As of 2026-11-06, `qwen.managed-agent.automation.enabled` defaults to true in both Java and the packaged configuration. Setting it or `QWEN_MANAGED_AGENT_AUTOMATION_ENABLED` to false disables the scanner and mutation routes; read routes always answer, and mutations still require Session Store. Enabling automation does not create definitions or re-enable disabled definitions. The server-first order holds: the Java store has validated both bodies since H6a and gains the cross-record checks here.
 14. **No WebShell surface, no Legacy change.** The daemon's `/scheduled-tasks` routes, `cronScheduler.ts` and `cronParser.ts` keep their behavior; a Managed definition never fires through them.
 15. **A crashed wake turn has one aftermath, retried until provably complete.** A wake turn its Harness died inside (classified `recovery`, never re-driven) ends through one idempotent sequence keyed on the journal and the checkpoint, not on which settle ran before it: its run fails with execution `outcome_unknown`; when its checkpoint holds in-progress Runtime executions they are stopped to terminal, settled cancelled — each cancelled `tool_result` committed once, so the checkpoint leaves `await_runtime` and the history stays shaped — and the wake session hands its Broker lease back, with the release attempted on every pass since the journal cannot say whether an earlier pass landed it; only then does the crashed input's own `turn_result` consume it, with a transient journal conflict retried, because an unproven consume keeps the input pending and every later load and every blocked pump pass re-runs the same settle — it is never dropped, or the re-block loop returns. The blocked pump's cycle re-arms itself across a dead pass, so a transient fault cannot take the reminders down with it. A crash whose run keeps the overlap count closed may have nothing left to load the Session (no slot fires, no Turn comes): the scanner's decision against a count-based refusal — never the open-Turn one — first asks the Harness a fourth verb, `reconcile_run`, for the blocking occurrences, committing no new fact; the verb's own load classifies and settles the crashed wake turn and answers its run — waiting out, for a bounded time, a pump pass in flight rather than settling the turn underneath it, so the answer typically carries the run the pass failed — and the decision prices the admission off those answers rather than the lagging mirror. A prompt arriving while such a park is still unsettled is refused before admission with `409 hosted_turn_recovery_in_progress` — the coordinator retries it past the pre-admission budget until the pump settles the park, since this is the only refusal that clears under the daemon's own recovery channel, while the durable `hosted_turn_recovery_required` still meets the budget; post-admission is exactly where no retry can reach. And a turn that ended without an answer (`error` or `cancelled`) keeps its prompt out of every later turn's model history, filtered against the journal at both history builders, so a crashed instruction never merges into an unrelated turn — the no-toolProfile path's older rule, now structural for every profile. Resolved runs price the retry at the mirror's own truth, never beside it: a reconcile's settle commits its mirror row in the same transaction that answers, so the recount subtracts only what still reads blocked rather than the answered runs once more; a reconcile counts an occurrence resolved only when its own run answers terminal — never on the route's bare `repaired` flag, whose session-scoped wake recovery may have settled an older neighbour while the asked run still lives; a reconcile that meets the definition's or the Session's death refresh-retires the mirror and records the slot `skipped(definition_retired)` instead of standing forever; and each decision's reconcile fan-out scales to the configured allow bound, at least two.

The R1-1 cell takes 10.8–11.4 s against its recorded 11.4–11.9 s, and every other case stays within its earlier range, so the budget entries above stand. Those runs predate the writer-scoped expiry; with it the class passes 9/9 again (104.8 s, and 107.8 s once it also checks that the leases lapsed), the Harness-kill cases at 11.9–13.4 s. The expiry is asserted rather than inferred from timings: without it each Harness-kill case would still pass, but only after waiting out the full 30 s lease (about 27 s longer per case in a review run).

Exactly three release controls (503, 200 same id, 200 other id), both configurations `released`, both fixture servers exit (`mcp.start` revisions 1 and 3, two `mcp.exit`), and no `mcp-configure`/`mcp-invoke` after the baseline. |
+
+Decisions:
+
+1. **One class, per-case config.** `HostedMcpRestartFaultGatesIT` adds `fixture2` only for this method's boot; `baseline(session, 2)` waits for both configurations to settle. No new class, no new profile, and the artifact root stays `target/fg12-cases/fg12d/`.
+2. **Two pins, two configurations.** The session's `mcpServers` carries `mcpPin(1)` and `mcpPin("fixture2", 3)`; the Harness installs one configuration per server. Revision 3 distinguishes the second server's fixture events from `fixture`'s revision 1.
+3. **The same-id retry is the claim.** The first 503 and the next 200 carry the same `${configurationId}:release` id; the third 200 carries the other configuration's id. The second configuration is reached only after the first settles.
+
+Mutation witness: `drainConfigurations` iterates `configurations.slice(0, 1)` in a copy of the packaged CLI. The two-server case is red at `settle must complete` because the second configuration stays active; the one-server case stays green, so this case is the one that pins the second configuration. The restored bundle is green.
+
+Budget: the two-server case measures 16.16–16.24 s standalone (two runs) on JDK 21, MySQL 8.4.6 and Linux x86_64; the ten-case class is 81.6 s. It adds 32 s (2×) to the shared healthy sum (11504 → 11536 s), so the `hosted-harness-mysql` fork moves to 11536 s and the Verify step to 203 minutes (12136 s of fork plus wrap); the job ceiling moves to 326 (293 + 33). The `hosted-mcp-gates` profile and the artifact root are unchanged.

+## Follow-up cell: detach refused while a tool result is unknown

The class's existing unknown-result cases (`stdioKillDuringRequestSettlesOutcomeUnknownOnMySql` and `workerKillDuringOperationSettlesOutcomeUnknownOnMySql`) stop at the unknown; this follow-up attempts the Harness detach route while the record is `recovery_blocked` / `outcome_unknown`.

+
+Decisions:
+
+1. **The Harness detach route is the gate.** The control-plane lifecycle close is exercised by the R1-1 and two-server cells; this cell calls `POST /session/{id}/detach` directly, which is the production detach that reaches `HostedMcpSession.close()`.
+2. **The unknown is permanent, not a timed window.** The stdio fixture is killed with an `ext://hold` read in flight, so the operation can only settle through a conclusive answer from its original Runtime generation. The detach has no window to race.
+3. **The refusal is one of the documented close answers.** The test accepts 409 `hosted_turn_active` (MCP busy/recovering) and 503 `managed_session_close_failed` / `hosted_mcp_recovery_required`; it rejects 200/204 and asserts no release control and an unchanged unknown record.
+
+Mutation witness: wrap `session.mcp?.close()` in the close path of a packaged CLI copy in `try { … } catch {}`; detach answers 204 and the case is red at the status assertion. The restored bundle is green.
+
+Budget: the case measures 27.4 s worst of two runs (27.4 s and 17.4 s) on JDK 21, MySQL 8.4.6 and Linux x86_64; booked at 55 s (2×). The `hosted-harness-mysql` fork moves to 11591 s, the Verify step to 204 minutes and the job ceiling to 327 (294 + 33).
+
+## Follow-up cell: lifecycle-v2 close with a stopped worker
+
+#15750's FG12d row also asks for a lifecycle-v2 close that meets a **stopped worker**, and its stop proof. The R1-1 cell replaces the Broker while the worker lives; this follow-up keeps the Broker and kills the durable worker after the configuration has drained, so the close can only finish through the original worker's persisted stop receipt.

+| `close-stopped-worker-stop-proof` | Drive the v2 close to `prepare_resources`; refuse the first owner release before forwarding so the configuration commits `drained` while the worker is alive; SIGKILL the durable worker; the next settle refuses; run the coordinator's MCP recovery arm (`recoverStoppedWorkspaceResources`) under the same claim; retry the settle | The first settle answers 503 `workspace_lifecycle_resources_unsettled` with the record `drained`, one `mcp-release` and one `mcp.exit`. The post-kill settle answers 503 as well. The recovery retires the binding: `binding_state` `RELEASED` with a persisted `drain_receipt_json` whose `bindingId` and `generation` match the retired row, the Runtime Session `RELEASED` and the storage holder cleared. The retried settle answers 200 and the configuration is `released`. Every proxy call after the kill is an owner release (no acquire, no MCP control); exactly one `mcp.start`, no replacement worker. |
+
+Decisions:
+
+1. **The worker dies after `drained`, not before.** A worker killed with the configuration still `active` leaves an undispatchable `mcp-release` — the unknown/blocked form the detach-unknown cell already gates. The stop-proof path is the release's: the configuration drains on the live worker, then the close must retire the binding without it.
+2. **The stop proof is the persisted drain receipt.** The recovery arm observes the original worker absent with matching loss evidence, stops it durably, and persists the receipt **before** it releases the session rows (`releaseStoppedSession` refuses a null receipt) and clears the storage holders (`releaseRetiredHolders` only clears on a persisted receipt). The cell reads `ma_runtime_binding.drain_receipt_json` and matches its `bindingId`/`generation` against the retired row; `RELEASED` without a receipt would be a fabricated retirement.
+3. **The test plays the coordinator's recovery trigger.** `SessionLifecycleCoordinator` runs `recoverStoppedWorkspaceResources` when the Harness settle fails for the MCP profile; the cell calls the same embedded-Broker arm under the admitted close's `{operationId, claimGeneration}`, exactly as it plays the DRAINING fence with a SQL update. The coordinator's trigger logic is not the subject — the Broker's drain and stop-proof machinery is. This extends the slice's "drive lifecycle v2 directly" decision to the one phase the Harness cannot finish alone.
+4. **No exchange with the dead process.** After the kill the proxy sees only owner releases: the blocked settle's 503 and the retried settle's 200. The recovery is in-JVM. No acquire and no MCP control may cross, and no second `mcp.start` may appear.
+
+Mutation witness: skip `renewal.persistDrainReceipt(proof, authority)` in `drainClaimedBinding`'s absence arm. The recovery then fails at the stop-proof step (`Original drain claim expired`) and the case errors before the binding assertions; the restored file is byte-identical (sha256-verified) and the case is green again.
+
+Budget: the case measures 33.09 s and 27.16 s standalone (18.21 s on the post-mutation restore run) on JDK 21, MySQL 8.4.6 and Linux x86_64; the twelve-case class is 152.9 s. It adds 67 s (2× the 33.1 s worst) to the shared healthy sum (11591 → 11658 s), so the `hosted-harness-mysql` fork moves to 11658 s, the Verify step to 205 minutes (12258 s of fork plus wrap, 42 s left) and the job ceiling to 328 (295 + 33).

+# Project Hooks Approval Gate
+
+[English](2026-10-19-project-hooks-approval-gate.md) | [简体中文](2026-10-19-project-hooks-approval-gate.zh-CN.md)
+
+Status: implemented, 2026-10-19.
+
+## Problem
+
+`security.folderTrust.enabled` defaults to `false`, and a disabled feature treats every folder as trusted. The workspace `.qwen/settings.json` is therefore merged in full, including its `hooks` block, and `Config.getProjectHooks()` only checks `isTrustedFolder()`. A freshly cloned repository can ship a `SessionStart` command hook that runs the moment `qwen` starts in it, with no prompt. Project MCP servers from the same file already have a hash-bound approval gate (issue #4615); project hooks have none.
+
+## Goals
+
+- A repository's hooks never run before the user has reviewed them.
+- Existing users keep their project hooks after a one-time approval; no change to the folder-trust default.
+- The gate mirrors the MCP one: user-local, per project, bound to the reviewed configuration, re-asked on change, never re-asked for a settled rejection.
+
+## Non-goals
+
+- Changing the default of `security.folderTrust.enabled`.
+- An ACP request for approving project hooks (ACP sessions simply do not load unapproved project hooks).
+- The LSP `.lsp.json` command path, which has the same shape of problem and is tracked separately.
+
+## Design
+
+### Approval store
+
+`packages/cli/src/config/hook-approvals.ts` persists `~/.qwen/hookApprovals.json` (`QWEN_CODE_HOOK_APPROVALS_PATH` overrides it) with one record per project root: `{ hash, status }`, `status` being `approved` or `rejected`. `hash` is a SHA-256 of the project `hooks` object as written in the file, before `${VAR}` resolution (startup resolves before the project `.env` loads, `/hooks` after, so a resolved block would hash differently on the two paths), together with the env the workspace supplies: each of its own `.env` files (the ones `loadEnvironment` reads that are not user-level, parsed, or `null` when unreadable) and its `settings.env`. Everything is serialised with sorted keys (null-prototype objects, so an own `__proto__` key is hashed too), so key order does not matter but any behavioural edit, including one made only through the project `.env`, changes it. The text is not parsed for variable names: a hook, or a script it starts, can read any variable, so no model of shell expansion would be complete. Variables the user sets outside the workspace are the user's own and are not hashed. A record whose hash does not match the live hooks, or whose status is neither value, counts as `pending`. Callers hand the Config a copy of the resolved block, because the hook registry tags loaded definitions in place and an ACP daemon reuses one settings instance across sessions. The project root is the folder holding the `.qwen/settings.json` the hooks came from, not the session's working directory, so `/cd` and `--worktree` do not move the key; it is normalised as in `mcpApprovals.json`. The file is written `0600` (an existing looser mode is tightened), and `QWEN_CODE_HOOK_APPROVALS_PATH` is excluded from project `.env` files like the sibling store paths and forwarded into a sandbox container. The file is read fresh on every check, so a long-lived ACP daemon sees decisions made elsewhere; a save re-reads it and replaces only its own project's record, and fails (leaving the hooks withheld) rather than overwrite a file it cannot read.
+
+`isProjectHooksPendingApproval(projectHooks, projectRoot)` is `true` when the block declares at least one hook the registry would run (a known event, and a `command`, `http` or `prompt` hook with its command, URL or prompt) and its state is not `approved` (pending or rejected). An absent, `null` or empty block, or one with nothing runnable, is never gated.
+
+### Core
+
+`ConfigParameters.projectHooksPendingApproval` records the startup decision; `undefined` means the session does not gate project hooks at all. While it is `true`, `getProjectHooks()` returns `undefined` after the existing trust check, and so does the legacy merged-`hooks` fallback in `getUserHooks()`, which can carry the same workspace block when no scopes were separated. `setProjectHooksPendingApproval()` lets the CLI clear the gate mid-session; the next `HookSystem.reload()` then registers them. `getWithheldProjectHooks()` returns the withheld block for display only, and the hooks listing behind the OpenTUI `/hooks` browser shows it with the reason `pendingApproval`, or `rejected` when the CLI recorded a rejection (`projectHooksRejected`). The ACP status reports it only as `enabled: false`, without the reason.
+
+### CLI startup
+
+`loadCliConfig` computes the flag from the unresolved project block and root the caller supplies (the startup and hosted callers all supply separated scopes; a bare merged `hooks` block cannot be attributed, so if it holds anything runnable the flag is `true`). It leaves the flag `undefined` under `--bare`, `--safe-mode`, `disableAllHooks` and a shell execution sandbox, where no hooks load. Under a YOLO approval mode asked for on the command line (`--yolo`, `--approval-mode yolo`) it sets the flag `false` with `projectHooksYoloExempt`, so the gate stays off only while the session is in YOLO: the first switch out of YOLO re-reads the decision, sets the flag and reloads the hooks. A YOLO mode that comes from settings does not exempt the hooks, because the workspace's own `tools.approvalMode` can set it.
+
+### Interactive approval
+
+`useProjectHooksApproval` (ink and OpenTUI share it) shows a dialog listing every hook as `Event  target [details]` when the state is strictly `pending`, worded from the unresolved block (whether a hook runs, and so whether the block is gated at all, is decided on the resolved one, so a `${VAR}` in `type` cannot hide a hook): the command with its `env` as `KEY=value`, `shell` and `async`; the URL with its header names and `allowedEnvVars`; the prompt text and any `model` override; the matcher comes last, so it cannot push the target off the row. Every repo-supplied string is reduced to one row with escapes, bidi and other format characters removed; a value over 200 code points is cut with a marker giving its length, so an elided tail is never silent. Each hook takes one row, cut to the dialog's text width with a `… [+N chars]` marker, and the list is capped to the rows the wrapped header leaves at that width (the finite list-dialog budget, in both renderers), down to just the "… and N more" row, so the options stay visible. Approve persists `approved`, clears the gate on the live `Config` and reloads the hook system; Reject persists `rejected` and leaves the hooks unloaded; Esc closes the dialog without storing anything and adds a transcript line saying the hooks were not loaded; the same block is not offered again this session, so `/hooks` can show it, and the next start (or an edit) asks again. A save that fails leaves the hooks withheld and says so. The dialog ranks after the MCP approval dialog. The ink `/hooks` browser marks withheld project hooks as not approved, or as rejected.
+
+### `/hooks` reload
+
+In a gated session the reload recomputes the gate from the freshly read workspace hooks before `HookSystem.reload()`, so a decision edited by hand applies without a restart and an edited block stays out of the registry. It emits `AppEvent.ProjectHooksPendingApprovalChanged` when the block is `pending` so the dialog asks again. An ungated session is left alone.
+
+### Headless runs
+
+A non-interactive session cannot prompt. Unapproved project hooks stay unloaded and `qwen -p` prints one stderr line saying so: for a pending block it points at an interactive run, for a rejected one it names the approvals file instead.
+
+## Decisions
+
+- **Gate regardless of folder trust.** A trusted folder means its settings are read, not that every command in them was reviewed; this matches the MCP gate and keeps the folder-trust dialog unchanged.
+- **One decision per project, not per hook.** Hooks are reviewed as the block the file declares; a per-hook queue would add UI for no extra safety.
+- **Only a command-line YOLO skips the gate.** The user chose to approve everything; a settings value could have been chosen by the repository.
+- **Rejection is remembered** so a rejected repository does not nag on every start, but any edit re-asks. Esc is not a rejection, so a dialog that is closed in passing is offered again on the next start.
+- **The workspace's env is part of what is approved, by content.** A project `.env` or `settings.env` could otherwise change what an approved hook runs without touching the block. Binding the whole source, rather than the names a command mentions, also covers scripts that read the environment themselves. Editing any value there asks again; the dialog shows no values, so it never displays a credential.
+- **The hash covers the `hooks` block only.** Other hook settings a project can set, such as `stopHookBlockingCap` (clamped to 100), tune how approved hooks run but run nothing themselves; folding them in would re-prompt every approved project for no new command.
+
+## Validation
+
+- Unit tests: store semantics and hash binding (`hook-approvals.test.ts`), startup gate conditions (`config.test.ts` in both packages), the dialog hook (`use-project-hooks-approval.test.ts`), and the `/hooks` reload (`hooksCommand.test.ts`).
+- Manual: `qwen -p` in a cloned repository that declares a `SessionStart` hook no longer runs it and warns on stderr; an interactive start shows the dialog, approving runs the hooks on the next event, and `~/.qwen/hookApprovals.json` holds the decision.
+
+## Acceptance criteria
+
+- With default settings, a repository hook never runs before the dialog is answered.
+- Approving once is enough until the project hooks change.
+- Rejecting keeps the hooks unloaded and does not re-prompt until they change.
+- User, system and extension hooks are unaffected.
+
+## Follow-up
+
+- ACP: a request to list and approve pending project hooks, mirroring the MCP one, and the withheld reason in the hooks status.
+- LSP: gate the workspace `.lsp.json` commands the same way.
+- Project skill and subagent frontmatter hooks: they need explicit folder trust instead (see [Explicit trust for repository execution](2026-11-03-project-execution-trust.md)).
+- A non-interactive way to approve project hooks (for CI), mirroring `qwen mcp approve`.

+# 项目 Hooks 审批闸门
+
+[English](2026-10-19-project-hooks-approval-gate.md) | [简体中文](2026-10-19-project-hooks-approval-gate.zh-CN.md)
+
+状态：已实现，2026-10-19。
+
+## 问题
+
+`security.folderTrust.enabled` 默认为 `false`，功能关闭时每个目录都被视为受信任。于是工作区 `.qwen/settings.json` 会被完整合并，包括其中的 `hooks`，而 `Config.getProjectHooks()` 只检查 `isTrustedFolder()`。一个刚克隆的仓库可以自带 `SessionStart` 命令 hook，在仓库目录启动 `qwen` 的瞬间就执行，没有任何提示。同一文件里的项目 MCP 服务器已经有按哈希绑定的审批闸门（issue #4615），项目 hooks 却没有。
+
+## 目标
+
+- 仓库自带的 hooks 在用户审阅之前绝不执行。
+- 现有用户一次审批后继续使用项目 hooks；不改目录信任的默认值。
+- 闸门与 MCP 的一致：用户本地、按项目、绑定审阅过的配置、变更后重新询问、已拒绝的不再反复询问。
+
+## 非目标
+
+- 修改 `security.folderTrust.enabled` 的默认值。
+- 为 ACP 增加审批项目 hooks 的请求（ACP 会话直接不加载未审批的项目 hooks）。
+- LSP `.lsp.json` 的命令路径，问题形态相同，另行跟踪。
+
+## 设计
+
+### 审批存储
+
+`packages/cli/src/config/hook-approvals.ts` 把决定持久化到 `~/.qwen/hookApprovals.json`（可用 `QWEN_CODE_HOOK_APPROVALS_PATH` 覆盖），每个项目根目录一条记录：`{ hash, status }`，`status` 为 `approved` 或 `rejected`。`hash` 是项目 `hooks` 对象按文件原文（`${VAR}` 解析之前；启动时在项目 `.env` 加载前解析、`/hooks` 在其后解析，解析后的块在两条路径上哈希不同），连同工作区提供的环境变量来源——它自己的每个 `.env` 文件（`loadEnvironment` 读取的非用户级文件，取解析结果，读不了时为 `null`）以及它的 `settings.env`——按键排序序列化后的 SHA-256（使用无原型对象，因此自有的 `__proto__` 键也会参与哈希），因此键顺序无关，但任何行为上的修改（包括只通过项目 `.env` 做的修改）都会改变它。不从命令文本里解析变量名：hook 或它启动的脚本可以读取任何变量，对 shell 展开的任何模拟都不可能完整。用户在工作区之外设置的变量属于用户自己，不参与哈希。哈希与当前 hooks 不匹配、或状态不是这两个值之一的记录视为 `pending`。调用方交给 Config 的是解析后块的副本：hook 注册表会原地给已加载的定义标注来源，而 ACP daemon 会在多个会话间复用同一个设置实例。项目根目录是 hooks 所在 `.qwen/settings.json` 的目录，而不是会话的工作目录，因此 `/cd` 与 `--worktree` 不会改变键；其规范化方式与 `mcpApprovals.json` 相同。文件以 `0600` 写入（已有的更宽松权限会被收紧），`QWEN_CODE_HOOK_APPROVALS_PATH` 与同类存储路径一样不允许由项目 `.env` 设置，并会转发进沙箱容器。每次检查都重新读取文件，因此长期运行的 ACP daemon 能看到在别处做出的决定；保存时重新读取并只替换本项目的记录，读不了文件时直接失败（hooks 保持扣留），而不是覆盖它。
+
+`isProjectHooksPendingApproval(projectHooks, projectRoot)` 在 hooks 块至少声明了一个注册表会运行的 hook（已知事件，且为带有命令、URL 或 prompt 的 `command`、`http` 或 `prompt` hook）且状态不是 `approved`（待定或已拒绝）时为 `true`。不存在、为 `null`、为空或没有可运行内容的块永远不受闸门约束。
+
+### Core
+
+`ConfigParameters.projectHooksPendingApproval` 记录启动时的判定；`undefined` 表示该会话完全不对项目 hooks 设闸门。为 `true` 期间，`getProjectHooks()` 在既有的信任检查之后返回 `undefined`，`getUserHooks()` 中旧的合并 `hooks` 回退也同样返回 `undefined`（未拆分作用域时它可能携带同一工作区块）。`setProjectHooksPendingApproval()` 允许 CLI 在会话中途解除闸门，下一次 `HookSystem.reload()` 即注册它们。`getWithheldProjectHooks()` 仅为展示返回被扣留的块，OpenTUI `/hooks` 浏览器背后的 hooks 列表以原因 `pendingApproval` 显示它们；CLI 记录了拒绝时（`projectHooksRejected`）原因为 `rejected`。ACP 状态只报告 `enabled: false`，不带原因。
+
+### CLI 启动
+
+`loadCliConfig` 根据调用方提供的未解析项目块及其项目根目录计算该标志（启动与 hosted 调用方都提供分离的作用域；单独的合并 `hooks` 块无法区分来源，只要其中有可运行的 hook 就设为 `true`）。在 `--bare`、`--safe-mode`、`disableAllHooks` 和 shell 执行沙箱下（此时不加载任何 hooks），该标志为 `undefined`。命令行要求的 YOLO 审批模式下（`--yolo`、`--approval-mode yolo`）该标志为 `false` 并带 `projectHooksYoloExempt`，闸门只在会话处于 YOLO 期间关闭：第一次切出 YOLO 时会重新读取决定、设置标志并重载 hooks。来自设置的 YOLO 模式不豁免 hooks，因为工作区自己的 `tools.approvalMode` 就能设置它。
+
+### 交互式审批
+
+`useProjectHooksApproval`（ink 与 OpenTUI 共用）在状态严格为 `pending` 时显示对话框，按 `Event  target [details]` 列出每个 hook，文字取自未解析的块（hook 是否会运行、进而整个块是否需要设闸，按解析后的块判断，因此 `type` 里的 `${VAR}` 藏不住 hook）：命令及其 `env`（以 `KEY=value` 显示）、`shell` 与 `async`；URL 及其请求头名称与 `allowedEnvVars`；prompt 文本及其 `model` 覆盖；matcher 放在最后，不会把执行目标挤出该行。仓库提供的每个字符串都压成一行，并去除转义序列、双向控制及其他格式字符；超过 200 个码点的值会被截断并标明原长度，被省略的尾部不会悄无声息。每个 hook 占一行，按对话框文本宽度截断并带 `… [+N chars]` 标记；列表按该宽度下换行后的标题所剩行数截断（两个渲染器都使用有限的列表对话框预算），最少只剩 "… and N more" 一行，保证选项始终可见。批准会持久化 `approved`、解除运行中 `Config` 的闸门并重载 hook 系统；拒绝会持久化 `rejected`，hooks 保持不加载；Esc 关闭对话框且不保存任何决定，并在会话记录中加一行说明 hooks 未加载；本会话内同一个块不再弹出，因此 `/hooks` 可以展示它，下次启动（或块被修改）时再次询问。保存失败时 hooks 保持扣留并给出提示。该对话框排在 MCP 审批对话框之后。ink 的 `/hooks` 浏览器把被扣留的项目 hooks 标为未批准或已拒绝。
+
+### `/hooks` 重载
+
+在设有闸门的会话中，重载在 `HookSystem.reload()` 之前用重新读取的工作区 hooks 重新计算闸门，这样手动修改的决定无需重启即可生效，修改过的 hooks 块也不会进入注册表；当其状态为 `pending` 时发出 `AppEvent.ProjectHooksPendingApprovalChanged`，让对话框再次询问。未设闸门的会话不受影响。
+
+### 无头运行
+
+非交互会话无法提示。未审批的项目 hooks 保持不加载，`qwen -p` 在 stderr 上打印一行说明：待定的块提示交互式运行一次，已拒绝的块则给出审批文件的位置。
+
+## 决策
+
+- **无论目录信任与否都设闸门。** 目录受信任意味着读取其设置，不代表其中每条命令都审阅过；这与 MCP 闸门一致，也不改动目录信任对话框。
+- **按项目而非按 hook 决定。** hooks 以文件声明的整个块为单位审阅；逐条排队只会增加 UI，不增加安全性。
+- **只有命令行的 YOLO 跳过闸门。** 那是用户自己选择批准一切；设置里的值可能是仓库选的。
+- **记住拒绝**，被拒绝的仓库不会每次启动都询问，但任何修改都会重新询问。Esc 不算拒绝，顺手关掉的对话框下次启动还会出现。
+- **工作区的环境变量按内容属于批准范围。** 否则项目 `.env` 或 `settings.env` 可以不动 hooks 块就改变已批准 hook 的行为。绑定整个来源而不是命令里提到的变量名，也覆盖了自行读取环境的脚本。修改其中任何值都会重新询问；对话框不显示任何值，因此不会把凭据显示出来。
+- **哈希只覆盖 `hooks` 块。** 项目可设置的其他 hook 相关设置，如 `stopHookBlockingCap`（上限钳制为 100），只调节已批准 hooks 的运行方式，本身不执行任何东西；把它们纳入哈希会让所有已批准项目重新询问，却没有新命令可审。
+
+## 验证
+
+- 单元测试：存储语义与哈希绑定（`hook-approvals.test.ts`）、启动闸门条件（两个包的 `config.test.ts`）、对话框 hook（`use-project-hooks-approval.test.ts`）、`/hooks` 重载（`hooksCommand.test.ts`）。
+- 手动：在声明了 `SessionStart` hook 的克隆仓库里运行 `qwen -p`，hook 不再执行并在 stderr 给出警告；交互式启动显示对话框，批准后 hooks 在下一次事件时运行，`~/.qwen/hookApprovals.json` 保存了决定。
+
+## 验收标准
+
+- 默认设置下，仓库 hook 在对话框得到回答之前绝不执行。
+- 审批一次即可，直到项目 hooks 发生变化。
+- 拒绝后 hooks 保持不加载，变化之前不再询问。
+- 用户、系统和扩展 hooks 不受影响。
+
+## 后续工作
+
+- ACP：增加列出并审批待定项目 hooks 的请求，与 MCP 的对应，并在 hooks 状态中带上扣留原因。
+- LSP：以同样方式为工作区 `.lsp.json` 的命令设闸门。
+- 项目 skill 与 subagent frontmatter 中的 hooks：改为需要显式目录信任（见[仓库代码执行需要显式信任](2026-11-03-project-execution-trust.zh-CN.md)）。
+- 非交互式审批项目 hooks 的方式（用于 CI），与 `qwen mcp approve` 对应。

 failure in `mvn_status` instead of aborting under errexit, the failure stops
 the remaining suites, and that deferred status fails the step after the copy.
 The downloads the failed run made are therefore published instead of
 re-fetched by the next leg, and a tolerated skip of the copy reports the same
 status rather than turning the step green. A red leg queues only as long as

 the three suites apart.

+
+The steps are the skill's (Section "Refusals" there): `retry` runs the call
+again, once — `busy` after the other helper, `partial` up to three times a
+round; `stop` stops the watch; `end_task` deletes the task that woke the
+round and ends it; `take_over` asks whether this session takes the watch
+over; `discard` runs `sync --discard` in its place; `foreground` runs the
+fix in the foreground; `rerun` answers the run's checks with a re-run;
+`needs_human` answers the call's items as needing a person; `fix_plan`
+corrects the reply plan; `report` reports the message and ends the start or
+the round. The step depends on the helper as well as the code, so that one
+code can mean what the step that called the helper needs. The `autofix_pr`
+tool returns a coded refusal with that line first, verbatim —
+`autofix-pr <command> refused: {…}` — followed by the rest of what the
+helper printed (git's or `gh`'s output). It takes the line only from a
+helper that exited 1, and only the last coded line with nothing but Node's
+warnings after it: a line a hook printed before the helper crashed is not
+its refusal. The tool runs its helpers with Node's warnings off
+(`NODE_NO_WARNINGS=1`), so a warning Node flushes after the line, which may
+run over several lines, cannot hide it. A message carries at most 8,000 characters as JSON, its head
+and its tail, with terminal controls dropped, so the line fits the 16 KiB
+of stderr the tool keeps. A refusal without the line — one of the tool's own, which
+says why in words, arguments yargs refused, or a CLI older than the codes
+— keeps the form the tool gave every refusal before the codes: the result
+starts `autofix-pr <command> refused (exit <n>).`, followed by the whole of
+the helper's stderr and what it printed on stdout, and a background fix's
+launch reads it as the last stderr line that names an error (`Error: …`,
+prefix stripped), or the last line. The skill handles it as the calling
+step says, and otherwise reports it. A defect in a helper rather than a
+refusal (an error that is no `AutofixPrRefusal`) prints its stack frames
+before the coded line, so where it happened is kept and the line stays
+last.

 ## Status and scope
 
 This change permits ordinary Managed Sessions on LOCAL and SSH_LOCAL storage to execute concurrently in the same directory. It covers both Session-isolated and Workspace-isolated workers. A Session still runs one Turn at a time. Resident and private CSI profiles retain their current admission, reservation, and retirement rules. Existing Agent/Workflow child-admission restrictions are outside this slice.

 Session 的审批模式同样约束闸门唤醒的回合。在 `default` 和 `auto-edit` 下，回合里的 shell 调用会发起审批 Action（§2，策略），没人应答的 Action 在审批超时（默认 10 分钟）后被拒绝。这样的回合等待期间，默认的 `skip` 重叠策略会跳过后面的时间槽，不跑探针。所以在这两种模式下，监视可以无人值守地唤醒 Session，但回合执行的命令要等人批准。如果被拒，探针不会再报这些事件：它输出时游标已经前移。README 里的 "Shell always asks permission" 说的是沿用部署审批模式的 Session（Shell 要求它为 `default` 或 `auto-edit`）。在 Harness 支持审批选择时，通过 WebShell 还可以直接以 Full Access（`yolo`）创建内置 Shell Session，或由所有者在 Workspace Shell 开启期间把 Session 切换过去（[审批选择设计](managed-approval-selection.zh-CN.md)）。之后闸门唤醒的回合执行命令就不再询问，而驱动它的部分内容是别人写的 PR 文本。

 Store a bounded Session-local settings snapshot in the existing registered configuration-installation journal domain. Its envelope supplies revision, operation identity and predecessor reference. The closed MCP content contains exact pins and enabled/removed state; removed entries remain tombstones so restoration can authorize historical configuration records. The base proposal in #15119 bounds 32 distinct historical server identities, including removed entries, and 16 enabled servers. Draft #15161 proposes changing that to 32 live selections (enabled or disabled), while keeping the 16-enabled bound and retaining every removed tombstone. This branch implements that alternative; it is a capacity-policy decision pending maintainer agreement, not an already accepted correction. A server identity cannot move to a lower definition revision after removal; deployments publish a new identity when resetting a definition lineage. Admission pins are revision zero. Preserve old logs without a settings snapshot.
 
-The live-selection alternative advances the public snapshot contract to 1.95.0 and aligns the Harness and Java readers. Removed records remain subject to the existing 64 KiB serialized-record bound; no tombstone compaction or unlimited history is promised. Older readers that cap the entire array at 32 cannot consume a larger snapshot, so a rollout must align readers before writing one. Downgrading those readers after such a write is not supported by this proposal.

 Every command carries an actor-scoped stable operation identity and expected settings revision. A retry queries the same original command; different content under the same identity conflicts. Concurrent revisions conflict before execution. Persist requested settings before changing physical connections, then record completion with existing MCP configuration/release receipts. An uncertain original effect blocks new work and is reconciled on its original owner; it is never replayed on another Runtime. Restart recovery retains command identity across interruption between release and configure. Historical drain status examines only configurations that existed before that command's durable intent, so a later enable cannot undo a completed disable receipt. The settings append transaction rechecks Plan, Turn and lifecycle admission under the same Session lock those mutations take.

 ### ACP prompt turns on the shared round (PR 2a)
 
-PR 2 moves ACP in steps. PR 2a moves the model round of a fresh user prompt: one that is not a retry, a continue or a restore, and not a Goal, channel or goal-proposal approval turn. The round is the loop's own `runModelRound`: one `LlmClient.sendMessageStream` call whose events go to ACP and whose terminal events become stop reasons. ACP keeps its tool step (`runToolCalls`, the next message after tools, the daemon tool-loop guards) and everything around the turn. PR 2b moves the tool batch of these turns onto the scheduler, and PR 2c-1 their stop point onto the client's chain. PRs 2c-2 to 2c-4 then move the other turns, so each of ACP's loop bodies changes once.

+### ACP turns that re-enter a prompt, and channel and Goal-proposal turns (PR 2c-2)
+
+PR 2c-2 puts five more kinds of ACP turn on the shared round, the shared tool batch and the client's stop point. Two are fresh prompts PR 2a left out: channel prompts and Goal-proposal approval turns. Three re-enter a turn the session already has: a retry, a continue of an interrupted turn and the restore of an unanswered `ask_user_question`. Goal turns, cron and background notifications move in PRs 2c-3 and 2c-4.
+
+| Turn                           | With the setting on                                                                                                                                                                                                                 |
+| ------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| channel prompt                 | a `UserQuery` like any fresh prompt, without the submitted prompt or workflow input, as today; its responses are not cut short by queued input, its tool results never end the turn, and its repeated-tool-failure guard stays off  |
+| Goal-proposal approval         | a `UserQuery`; the session settles the proposal as today, and a Todo Stop Guard that gives way, or the Stop hook's cap, keeps the proposal from starting a Goal                                                                     |
+| retry                          | ACP strips the failed attempt and puts it back if the retry never sends, as today; the first round is a `Retry` with `historyPromptId`, the attempt's identity, and UserPromptSubmit's verdict from `admitUserPrompt`               |
+| continue                       | ACP strips the interrupted run, or closes the interrupted calls, as today; the first round is a `Retry` with `historyPromptId` and no UserPromptSubmit; a first request that never goes out puts the interrupted run back as it was |
+| restore of `ask_user_question` | ACP asks the question again with its own tool step; the answer is the first round, a `Retry`; later batches run on the shared batch                                                                                                 |
+
+A re-entered turn's first round is a `Retry`, not a `ToolResult`, even when it carries tool results: a `ToolResult` does not start the client's interaction, so the previous prompt's loop-detector counts would carry over and UserPromptSubmit would run on the results. Headless continues an interrupted turn with a `ToolResult` because each of its runs is a new process. A `Retry` gets no system reminders from the client, so ACP adds its plan, arena and output-style reminders to it as today, and the todo reminder ACP takes is the one the client would take.
+
+The restored question keeps ACP's tool step: the shared batch records every result, and a question left unanswered on a timeout must stay unrecorded so a later load can ask it again.
+
+Whether a re-entered turn's first request went out is read from the chat's push count when the round ends, on every exit. A request in history replaces what the turn stripped and carries the restore's notices, even when its response then fails; a request that never went out leaves history as the turn found it, and the notices stay pending.
+
+The core changes of this step: `userTurnRecordedByHost` also covers a `Retry`, whose todo work chain the host started; `promptAdmission` is accepted on a `Retry`; and the new input `historyPromptId`, the history identity a `Retry`'s request carries, spent by its first request.
+
+### ACP Goal turns (PR 2c-3)
+
+PR 2c-3 puts ACP's Goal turns on the shared round, the shared tool batch and the client's stop point: the continuations the Goal runtime schedules, and a user prompt that runs while a Goal is active. ACP keeps the scheduling around the turn as today: the queue the runtime fills, the claim of a user prompt's turn, the start and end notifications, and the settlement of the turn.
+
+| Turn                          | With the setting on                                                                                                                                                    |
+| ----------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| runtime continuation          | a `Goal` round under the turn's permit; ACP records the continuation's message and adds its system and todo reminders as today, and the round runs no UserPromptSubmit |
+| user prompt while a Goal runs | a `UserQuery` under the permit ACP claimed for it, otherwise as any fresh prompt                                                                                       |
+
+Every round of the turn, its tool-result requests and continuations included, carries the permit, the turn key and the origin. The round's own signal is the Goal signal, so the client leaves a cancelled round, or one cut short for queued input, to ACP, which tells a new prompt's handoff from a cancel as today. The client handles the rest: once the Stop hook and the Todo Stop Guard let the turn stop, it finishes the Goal turn, and a round that fails, loops or reaches the Stop hook's cap pauses the Goal with the reason ACP gives it. A turn that a tool ends, or that ACP's loop protection stops, still settles in ACP, which records the end of the turn with the tool that ended it.
+
+The model has started once the round's request reached history, read from the chat's push count; a runtime continuation is marked delivered then, before the client can finish the turn.
+
+Input a round took as its response finished is answered within the turn, as today. So when the Todo Stop Guard gives way to such input, ACP ends the round's signal instead of letting the client finish the Goal turn, and the next round answers the input under the same permit. Once the Stop hook's cap has paused the Goal, a round that still answers input taken then runs outside the Goal.
+
+The core changes of this step: `userTurnRecordedByHost` also covers a `Goal` round, whose message the host recorded, and a stop policy's continuation keeps the Goal fields of its send, so it runs under the same permit.
+
+### ACP cron and background-notification turns (PR 2c-4)
+
+PR 2c-4 puts ACP's last two kinds of turn on the shared round, the shared tool batch and the client's stop point: the cron turns the scheduler fires, loop ticks included, and the turns a background task's result starts. ACP keeps the scheduling around the turn as today: the queues, the admission of a notification turn, the echo of a cron prompt, the start and end notifications, and the channel delivery of a scheduled reply.
+
+The prompt loop's shared round becomes a method that the three loops share. The prompt loop passes it what only a prompt has: putting a re-entered turn back when its request never went out, the Goal marks, and the loop stop that pauses a Goal. The cron and notification loops run their tool batches around it as the prompt loop does.
+
+| Turn                    | With the setting on                                                                                                                                                                                            |
+| ----------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| cron                    | a `Cron` round; the client resets the turn's memory state, adds its system and todo reminders and recalls memory, as for the other surfaces; ACP records the prompt once its request reached history, as today |
+| background notification | a `Notification` round; ACP records the notification and adds its system and todo reminders, as today, and shows each response as one background message once it ended                                         |
+
+Both kinds of turn run the Todo Stop Guard as their stop policy, after the Stop hook. Queued input does not cut their responses short, as today, and is taken at a tool boundary; it no longer continues a notification turn at its stop point, but starts the next turn, as on a prompt since PR 2c-1. A cron turn keeps ACP's interaction span; a notification turn, which has none on ACP's side, gets the client's.
+
+The core change of this step: `userTurnRecordedByHost` also covers a `Cron` and a `Notification` send, whose prompt or notification the host records.
+
+### The Ink TUI on the shared loop (PR 3)
+
+The Ink TUI already sends every model round through `LlmClient.sendMessageStream`, from one function, `submitQuery`, for every kind of turn. Its loop is split by React instead: a response that requested tools hands them to the scheduler and returns, and the scheduler's completion callback sends the results as a new `ToolResult` turn. Moving the TUI means awaiting that batch, so it moves in these steps:
+
+| Step  | Content                                                                                                                                                                                                                                                                                                                    |
+| ----- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |

+PR 3a puts every model round of the TUI on `runModelRound`. The round sends the same request with the same options, so the TUI's stream processor keeps handling every event as today. What moves is the part of the round the loop already owns:
+
+| The TUI today                                                          | With the setting on                                          |
+| ---------------------------------------------------------------------- | ------------------------------------------------------------ |
+| the stream processor collects `ToolCallRequest` events                 | `runModelRound` collects them                                |
+| the processor drops the collected calls on `Retry` and `ModelFallback` | `runModelRound` drops them                                   |
+| a detected loop keeps the collected calls from being scheduled         | any stop reason of the round keeps them from being scheduled |
+
+A stop reason other than a detected loop comes from an event the client sends before it asks the model (the session turn cap, the session token limit, a blocked prompt) or from a cancel, which ends the round as today, so its round has no calls to schedule. The TUI therefore behaves the same with the setting on and off.
+
+PR 3b-1 runs a shared round's tool calls as one batch of the shared loop, `runToolBatch`, on an executor over the TUI's scheduler. The scheduler takes the batch as before, so the tool group, its approvals and the Mod tool middleware are unchanged; the batch's completion comes back to the executor instead of the scheduler's callback. The TUI's completion step then runs as today with the batch's results:
+
+| The TUI today                                                                         | With the setting on                                                                                                                     |
+| ------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------- |
+| the stream processor answers a provider replay and holds it until the batch completes | the batch answers it in place                                                                                                           |
+| the completion step orders, finalizes and records the results                         | the batch orders and finalizes them; the completion step records the ones it sends, after its session check, with the batch's recording |
+| the completion step counts each completed call toward the session's tool calls        | the batch counts them, except the calls the Mod tool middleware counted per attempt and the skipped siblings of a plan-mode entry       |
+| a batch that completes during a model stream waits for it to end                      | the same: it is handled when the stream ends, against history as it is then, in one continuation with the other waiting batches         |
+| the completion step continues the turn with a `ToolResult` round                      | the same, with the batch's results                                                                                                      |
+
+A response made only of provider replays keeps the current path, since it runs nothing.
+
+PR 3b-2a moves the TUI's stops into the batch. The batch ends only when no model stream is active, as the TUI holds a batch that completes during a stream today, so the batch sees the session as the continuation will:
+
+| The TUI today                                                                                                                                 | With the setting on                                                                                                                                                                                |
+| --------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| the completion step stops without a continuation after a quota model switch, or when a background agent launch spent the last background slot | the batch's result callback ends the batch on either; the completion step checks both again when it sends, since a batch may wait for another stream to end, and stops with the results in history |
+| a tool that ends the turn ends a Goal turn; outside one the turn continues                                                                    | it ends the turn either way, with its results in history                                                                                                                                           |
+
+Batches that wait for the streams join the queue that the end of the last stream drains, so the results of every batch completed during one stream go out in one continuation, as today, in the order the batches completed.
+
+PR 3b-2b has the turn await its batch. The batch's completion step still stops the turn or sends its next round, and the turn awaits both, so the history repair, the split by interaction owner and the tool-use summary run in the turn, right before the next round:
+
+| The TUI today                                                                                          | With the setting on                                                                                           |
+| ------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------- |
+| a round returns once its stream ended, and its batch's completion step sends the next round            | the round's turn awaits the batch, its completion step and the round that step sends                          |
+| the scheduler starts no queued batch until the completion step returned, after the next round's stream | until the completion step stopped the turn or is about to send the next round, whose calls need the scheduler |
+| a batch whose executed calls history all answered sends nothing                                        | the same: the batch's replay answers do not go out alone                                                      |
+
+When the turn's stream ends while another stream is active, which may be the stream that sent its round, the turn does not wait: a response of provider replays alone sends its answers before its own stream closes. The batch then waits for the streams to end and completes on its own, as before, and batches that wait for the streams still go out in one continuation.
+
+PR 3c-1 has the turn send the round its batch continues with. The batch's completion step still repairs history, splits the results by interaction owner, starts the tool-use summary and checks the stops, then hands the next round to the turn. The turn builds it as the loop's `nextRound` builds a round after its batch, and sends it:
+
+| The TUI today                                                                                                                            | With the setting on                                           |
+| ---------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------- |
+| the completion step takes the input queued for the tool boundary, mid-turn messages and then teammate messages, and sends the next round | the turn takes that input after the batch and sends the round |
+
+Until the turn sends the round, the batch keeps the scheduler and keeps the TUI off Idle, so queued batches and idle work do not start in between. A turn that does not wait for its batch, because another stream is active, leaves the round to the batch, which sends it itself. Batches that wait for the streams still go out in one continuation, which the turn whose stream ends last sends.
+
+A retry with Ctrl+Y already runs on the shared round and, from PR 3b-2b, awaits its batch. PR 3c-1 adds the retry scenarios to the Ink parity suite, with a retried tool-result round whose response calls a tool, and a scenario for input queued while a tool runs.

-The suite runs in the integration job. A scheduled job also runs the whole headless integration suite with the setting on.
+**Ink scenarios** (`integration-tests/interactive/ink-agent-loop-parity.test.ts`). The TUI runs in a pseudo-terminal against the fake server. The suite compares the two runs' request bodies as sent, with the system prompt, the tools offered and each message's `reasoning_content`, and their session's chat records, with usage. It also checks each run's number of requests, and, through the debug log, that only the run with the setting on sends its rounds and runs its tool batches on the shared loop, as many as the scenario has. A scenario that sends and records nothing, such as a blocked prompt, checks the notice on each run's last screen instead; the screen is not compared otherwise, since it repaints on timers:
+

+- a thought before a tool, whose second request replays the reasoning;

 ## Compatibility
 
-- With the setting off, no surface changes. The shared code that changes is additive: the scheduler's optional `beforeToolLaunch`, from PR 2a the `Turn` event fields and send options above, from PR 2b the exported `runToolBatch` and the scheduler's `refuseToolCall` and `onPermissionPromptTerminalSequence`, and from PR 2c-1 `stopPolicies`, which change nothing for a caller that does not use them.

 - With the setting on, headless differs from today in these intended ways. Most follow from scheduling a batch as one unit, as the TUI already does:
   - a stream-json message past `--max-session-turns` ends the run at the session turn limit, as `-p` does (the error on stderr, exit code 53), instead of a success that repeats the previous answer (#15325);
   - a notification turn (cron, monitor and other queued items) counts each of its model rounds toward `--max-session-turns`, as the main turn does, instead of one turn for the whole item, so a run whose notification turns call tools can reach the limit sooner;
-  - a batch's PreToolUse hooks and approvals (stream-json `can_use_tool`) run for all of its calls before any of them is launched, instead of one call at a time; under `--max-tool-calls`, a call past the budget can be approved and then stopped before it runs;

   - a PostToolBatch hook fires once per batch with all of its calls, and the batch output budget applies across the batch; today each call is its own batch;
   - telemetry follows the batch, as in the TUI: a plan-mode entry's siblings are logged as failed tool calls, also in the JSON `stats`, and a call stopped before its launch still has a tool span; with Mod tool hooks the calls are still scheduled one at a time, so neither applies;

+### 重新进入轮次的 ACP prompt，以及 channel 和 Goal 提案轮次（PR 2c-2）
+
+PR 2c-2 让另外五类 ACP 轮次使用共享模型轮、共享工具批和 client 的 stop 点。其中两类是 PR 2a 没有纳入的全新 prompt：channel prompt 和 Goal 提案审批轮次。另外三类重新进入会话中已有的轮次：retry、继续被打断的轮次（continue），以及恢复一个未回答的 `ask_user_question`（restore）。Goal 轮次、cron 和后台通知在 PR 2c-3 和 2c-4 中迁移。
+
+| 轮次                     | 设置开启后                                                                                                                                                                       |
+| ------------------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| channel prompt           | 与其他全新 prompt 一样是 `UserQuery`，和现在一样不带 submitted prompt 和 workflow 输入；它的回复不会被排队的输入打断，它的工具结果从不结束这一轮，重复工具失败守卫保持关闭       |
+| Goal 提案审批            | `UserQuery`；会话和现在一样结算提案；Todo Stop Guard 让位或 Stop hook 达到上限时，提案不会启动 Goal                                                                              |
+| retry                    | 和现在一样由 ACP 剥离失败的那次尝试，retry 一直没有发出时再把它放回；第一轮是 `Retry`，带上那次尝试的标识 `historyPromptId`，以及 `admitUserPrompt` 给出的 UserPromptSubmit 结果 |
+| continue                 | 和现在一样由 ACP 剥离被打断的那段输入，或关闭被打断的调用；第一轮是 `Retry`，带 `historyPromptId`，不运行 UserPromptSubmit；第一条请求一直没有发出时，被打断的那段输入按原样放回 |
+| 恢复 `ask_user_question` | ACP 用自己的工具步骤重新提问；回答作为第一轮，即一个 `Retry`；之后的批次使用共享工具批                                                                                           |
+
+重新进入的轮次即使带着工具结果，第一轮也是 `Retry` 而不是 `ToolResult`：`ToolResult` 不会开启 client 的一次交互，上一个 prompt 的循环检测计数会延续下来，UserPromptSubmit 也会在这些结果上运行。headless 用 `ToolResult` 继续被打断的轮次，是因为它每次运行都是一个新进程。client 不给 `Retry` 加系统提醒，所以 ACP 和现在一样为它加上 plan、arena 和 output-style 提醒；ACP 取走的 todo 提醒就是 client 会取的那一条。
+
+被恢复的问题保留 ACP 的工具步骤：共享工具批会记录每一个结果，而因超时没有回答的问题必须保持未记录，之后加载时才能再次提问。
+
+重新进入的轮次的第一条请求是否已经发出，在模型轮结束时按 chat 的推送计数判断，每条退出路径都一样。已进入历史的请求替换轮次剥离的内容，并带上 restore 的提醒，即使随后响应失败也是如此；一直没有发出的请求让历史保持轮次开始时的样子，提醒保持待发。
+
+这一步对 core 的改动：`userTurnRecordedByHost` 也覆盖 `Retry`，表示宿主已经启动了它的 todo 工作链；`Retry` 也接受 `promptAdmission`；新增输入 `historyPromptId`，即 `Retry` 的请求在历史中带的标识，由第一条请求使用。
+
+### ACP 的 Goal 轮次（PR 2c-3）
+
+PR 2c-3 让 ACP 的 Goal 轮次使用共享模型轮、共享工具批和 client 的 stop 点：包括 Goal runtime 安排的续写，以及 Goal 进行中运行的用户 prompt。轮次外围的调度和现在一样留在 ACP：runtime 填充的队列、用户 prompt 所在轮次的认领、开始和结束通知，以及轮次的结算。
+
+| 轮次                     | 设置开启后                                                                                                                         |
+| ------------------------ | ---------------------------------------------------------------------------------------------------------------------------------- |
+| runtime 续写             | 在这一轮的 permit 下的 `Goal` 模型轮；和现在一样由 ACP 记录续写消息，并加上它的系统提醒和 todo 提醒；这一轮不运行 UserPromptSubmit |
+| Goal 进行中的用户 prompt | 在 ACP 为它认领的 permit 下的 `UserQuery`，其余与任何全新 prompt 相同                                                              |
+
+这一轮的每个模型轮，包括工具结果请求和续发请求，都带上 permit、轮次 key 和来源。模型轮自己的 signal 就是 Goal signal，因此被取消的模型轮，或因排队输入被打断的模型轮，client 都交给 ACP 处理，ACP 和现在一样区分新 prompt 的接手和取消。其余的由 client 处理：Stop hook 和 Todo Stop Guard 允许这一轮停下后，client 结束这个 Goal 轮次；模型轮失败、出现循环或达到 Stop hook 上限时，client 按 ACP 给出的原因暂停 Goal。被工具结束的轮次，或被 ACP 的循环保护停下的轮次，仍由 ACP 结算，ACP 用结束这一轮的那个工具记录轮次结束。
+
+模型轮的请求进入历史后，就算模型已经开始，这由 chat 的推送计数判断；runtime 续写也在这时标记为已送达，早于 client 可能结束这一轮的时刻。
+
+模型轮在响应结束时取到的输入，和现在一样在这个轮次内答复。因此 Todo Stop Guard 为这样的输入让位时，ACP 结束这个模型轮的 signal，而不是让 client 结束这个 Goal 轮次，下一个模型轮在同一个 permit 下答复这条输入。Stop hook 达到上限、Goal 已经暂停之后，仍要答复已取到输入的模型轮在 Goal 之外运行。
+
+这一步对 core 的改动：`userTurnRecordedByHost` 也覆盖 `Goal` 模型轮，表示宿主已经记录了它的消息；stop policy 的续发请求保留原请求的 Goal 字段，因此在同一个 permit 下运行。
+
+### ACP 的 cron 和后台通知轮次（PR 2c-4）
+
+PR 2c-4 让 ACP 最后两类轮次使用共享模型轮、共享工具批和 client 的 stop 点：调度器触发的 cron 轮次（包括 loop tick），以及后台任务结果启动的轮次。轮次外围的调度和现在一样留在 ACP：队列、通知轮次的准入、cron prompt 的回显、开始和结束通知，以及定时回复的 channel 投递。
+
+prompt 循环里的共享模型轮改为三个循环共用的方法。prompt 循环把只有 prompt 才有的部分传给它：请求没有发出时把重新进入的轮次放回原样、Goal 标记，以及暂停 Goal 的循环停止。cron 和通知循环像 prompt 循环一样，在它外面运行自己的工具批。
+
+| 轮次     | 设置开启后                                                                                                                                       |
+| -------- | ------------------------------------------------------------------------------------------------------------------------------------------------ |
+| cron     | `Cron` 模型轮；和其他界面一样，由 client 重置这一轮的记忆状态、加上它的系统提醒和 todo 提醒并召回记忆；ACP 和现在一样在请求进入历史后记录 prompt |
+| 后台通知 | `Notification` 模型轮；ACP 和现在一样记录通知、加上它的系统提醒和 todo 提醒，并在每个响应结束后把它作为一条后台消息显示                          |
+
+两类轮次都在 Stop hook 之后运行 Todo Stop Guard 作为 stop 策略。排队的输入和现在一样不会打断它们的响应，在工具边界取入；在 stop 点它不再让通知轮次继续，而是启动下一轮，和 PR 2c-1 以来的 prompt 一样。cron 轮次保留 ACP 的交互 span；通知轮次在 ACP 一侧没有 span，改用 client 的。
+
+这一步对 core 的改动：`userTurnRecordedByHost` 也覆盖 `Cron` 和 `Notification` 发送，表示由宿主记录 prompt 或通知。
+
+### Ink TUI 迁到共享 loop（PR 3）
+
+Ink TUI 的每个模型轮已经通过 `LlmClient.sendMessageStream` 发送，所有类型的轮次都由同一个函数 `submitQuery` 发出。它的 loop 是被 React 拆开的：请求了工具的响应把工具交给 scheduler 后就返回，由 scheduler 的完成回调把结果作为新的 `ToolResult` 轮次发出。迁移 TUI 就是要等待这个工具批，因此分以下几步：
+
+| 步骤  | 内容                                                                                                                                                                                                                |
+| ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| 3a    | 每个模型轮改用 loop 的 `runModelRound`；TUI 保留自己的工具步骤；Ink 对拍测试                                                                                                                                        |
+| 3b-1  | 一个模型轮的工具调用作为一个共享工具批运行，底层是 TUI 的 `InteractiveModToolScheduler`，界面、审批和 Mod 工具中间件不变；去重和收尾由 loop 负责，TUI 用 loop 的记录方式记录它发送的结果；由 TUI 的完成步骤续发轮次 |
+| 3b-2a | 工具批在没有模型流进行时结束，即 TUI 可以发送的时刻；额度切换模型时的停止和后台 agent 容量用尽时的停止改由工具批结束；结束轮次的工具会结束轮次                                                                      |
+| 3b-2b | 工具批由轮次等待完成，由轮次发出下一轮；检查下一轮发送内容的步骤（历史修复、按交互 owner 拆分、工具使用摘要）改为下一轮之前的步骤                                                                                   |
+| 3c-1  | 工具边界取入的输入改走 loop 的下一轮；retry                                                                                                                                                                         |
+| 3c-2  | cron、后台通知、teammate 和 Goal 轮次                                                                                                                                                                               |
+| 3d    | 默认开启，随后删除现有 loop                                                                                                                                                                                         |
+
+PR 3a 把 TUI 的每个模型轮都放到 `runModelRound` 上。模型轮用相同的选项发送相同的请求，因此 TUI 的流处理器仍和现在一样处理每个事件。迁走的是 loop 本来就负责的那部分：
+
+| TUI 现在                                                 | 开启设置后                                |
+| -------------------------------------------------------- | ----------------------------------------- |
+| 流处理器收集 `ToolCallRequest` 事件                      | 由 `runModelRound` 收集                   |
+| 流处理器在 `Retry` 和 `ModelFallback` 时丢弃已收集的调用 | 由 `runModelRound` 丢弃                   |
+| 检测到循环时不调度已收集的调用                           | 模型轮的任何 stop reason 都不调度这些调用 |
+
+除检测到循环外，其他 stop reason 要么来自 client 在请求模型之前发出的事件（会话轮次上限、会话 token 上限、被拦截的 prompt），要么来自取消，而取消和现在一样结束这一轮，所以这些模型轮都没有要调度的调用。因此设置开启和关闭时，TUI 的行为相同。
+
+PR 3b-1 把共享模型轮的工具调用作为共享 loop 的一个工具批（`runToolBatch`）运行，executor 底层是 TUI 的 scheduler。scheduler 和以前一样接收这一批，因此工具组、审批和 Mod 工具中间件都不变；这一批的完成结果交回 executor，而不是 scheduler 的回调。随后 TUI 的完成步骤用这一批的结果，和现在一样运行：
+
+| TUI 现在                                       | 开启设置后                                                                            |
+| ---------------------------------------------- | ------------------------------------------------------------------------------------- |
+| 流处理器应答 provider 重放，并暂存到这一批完成 | 由工具批就地应答                                                                      |
+| 完成步骤给结果排序、收尾并记录                 | 由工具批排序和收尾；完成步骤在会话检查之后，用工具批的记录方式记录它发送的结果        |
+| 完成步骤把每个完成的调用计入会话的工具调用数   | 由工具批计入，但 Mod 工具中间件已按尝试计入的调用、plan mode 入口被跳过的同批调用除外 |
+| 在模型流进行中完成的工具批等待它结束           | 相同：流结束时按当时的历史处理，并和其他等待中的工具批合并为一次续发                  |
+| 完成步骤以 `ToolResult` 轮次续发               | 相同，使用这一批的结果                                                                |
+
+只由 provider 重放组成的响应不运行任何调用，因此保留现有路径。
+
+PR 3b-2a 把 TUI 的停止移入工具批。工具批只在没有模型流进行时结束，就像现在 TUI 会暂存在流进行中完成的工具批一样，因此工具批看到的会话和续发时相同：
+
+| TUI 现在                                                                          | 开启设置后                                                                                                                         |
+| --------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------- |
+| 额度切换模型后，或者后台 agent 启动占用了最后一个后台名额时，完成步骤停止且不续发 | 工具批的结果回调在这两种情况下都结束工具批；工具批可能要等另一个流结束，因此完成步骤在发送时再检查这两种情况，停止时把结果写入历史 |
+| 结束轮次的工具会结束 Goal 轮次；在 Goal 轮次之外，轮次继续                        | 两种情况都结束轮次，结果写入历史                                                                                                   |
+
+等待模型流的工具批会加入最后一个流结束时排空的队列，因此同一个流期间完成的所有工具批，其结果和现在一样在一次续发中发出，顺序与工具批完成的顺序一致。
+
+PR 3b-2b 让轮次等待自己的工具批。工具批的完成步骤仍然结束轮次或发出下一轮，轮次等待这两者，因此历史修复、按交互 owner 拆分和工具使用摘要在轮次中、在下一轮之前运行：
+
+| TUI 现在                                                               | 开启设置后                                                                   |
+| ---------------------------------------------------------------------- | ---------------------------------------------------------------------------- |
+| 一轮在它的流结束后就返回，由工具批的完成步骤发出下一轮                 | 这一轮所在的轮次等待工具批、它的完成步骤，以及这个步骤发出的那一轮           |
+| 完成步骤返回之前（在下一轮的流结束之后），scheduler 不启动排队的工具批 | 直到完成步骤结束了轮次，或即将发出下一轮为止，因为下一轮的调用需要 scheduler |
+| 已执行的调用全部被历史应答过的工具批不发送任何内容                     | 相同：这一批的重放应答不会单独发出                                           |
+
+如果轮次的流结束时还有另一个流在进行（它可能就是发出这一轮的流），轮次不等待：只由 provider 重放组成的响应会在自己的流关闭之前发出应答。这时工具批和以前一样等待各个流结束后自行完成，等待模型流的各个工具批仍在一次续发中发出。
+
+PR 3c-1 让轮次发出工具批接着发出的那一轮。工具批的完成步骤仍然修复历史、按交互 owner 拆分结果、启动工具使用摘要并检查各项停止条件，然后把下一轮交给轮次。轮次像 loop 的 `nextRound` 在工具批之后构建一轮那样构建它，并把它发出：
+
+| TUI 现在                                                                                   | 开启设置后                               |
+| ------------------------------------------------------------------------------------------ | ---------------------------------------- |
+| 完成步骤取走排队到工具边界的输入（先是 mid-turn 消息，然后是 teammate 消息），并发出下一轮 | 轮次在工具批之后取走这些输入并发出这一轮 |
+
+在轮次发出这一轮之前，工具批一直占着 scheduler，并让 TUI 保持非 Idle，因此排队的工具批和空闲时的任务不会在中间开始。如果另一个流还在进行，轮次不等待自己的工具批，就把这一轮留给工具批，由工具批自己发出。等待模型流的各个工具批仍在一次续发中发出，由流最后结束的那个轮次发出。
+
+Ctrl+Y 的重试已经走共享轮次，并从 PR 3b-2b 起等待自己的工具批。PR 3c-1 在 Ink 对拍套件中加入重试场景，包括重试的工具结果轮的响应又调用工具；还加入工具运行期间排队的输入这一场景。

 - 设置开启时，headless 与现在相比有以下有意的差异。其中大多数源于把一批调用作为一个整体调度，这也是 TUI 现在的做法：
   - 在 stream-json 中，超过 `--max-session-turns` 的消息会在会话轮数上限处结束运行，与 `-p` 相同（错误写到 stderr，退出码 53），而不是返回一个重复上一条回答的成功结果（#15325）；
   - 通知轮次（cron、monitor 等排队条目）的每一轮模型调用都计入 `--max-session-turns`，与主轮次相同，而不是整个条目只计一轮，因此通知轮次中调用工具的运行可能更早到达上限；
-  - 一批调用的 PreToolUse hook 和审批（stream-json 的 `can_use_tool`）会在这一批的任何调用启动之前为所有调用执行，而不是一次一个调用；在 `--max-tool-calls` 下，超出预算的调用可能先被审批通过，然后在执行前被停下；

   - PostToolBatch hook 每批触发一次，带上这一批的所有调用，批次输出预算也按整批计算；现在每个调用都是单独的一批；
   - 遥测按整批记录，与 TUI 一致：进入 plan mode 那个调用的同批调用记为失败的工具调用（JSON 输出的 `stats` 也计入），启动前被拦下的调用仍有工具 span；带 Mod 工具 hook 时调用仍逐个调度，这两点都不适用；

+`check` takes the options of the later phases and prints them into its plan, so the rows describe the run the operator will make. Each value is quoted for the shell, and a control character in one is spelled as the three-digit octal escapes of its bytes inside `$'...'`, so the plan line carries none to the terminal; bash, ksh and zsh read it back as the value, a digit after it included, which a `\x` escape would let ksh read on into, while `/bin/sh` as dash does not read `$'...'`, so such a line is pasted into one of those. `stop` and `install` repeat all rows above `backup-tools`; `backup` repeats the last two.

+The `database` row reads the Flyway scripts from both server jars: the manifest's control-plane component, entries named as Flyway names versioned, undo and repeatable scripts under `db/**/` on the jar's classpath. That is `BOOT-INF/classes/db/**/`, and `db/**/` at the root of each nested jar in `BOOT-INF/lib/`, where the server's modules ship it since the server was split into them. Spring Boot stores a nested jar uncompressed, so the reader reads its directory in place; a compressed one, which Spring Boot would not load, is skipped. A script keeps its path as its name wherever it ships, so one moved from the classes into a module is unchanged. A path shipped twice is one script when the copies match; when they differ, which one Flyway gets depends on the class loader, so the jar is unreadable to the row, which names the two places, `BOOT-INF/classes` or the nested jar, that ship them. A local header's extra field, which archivers add for timestamps or alignment and the central directory need not repeat, is skipped before each entry's data.

 Spring resolves `qwen.managed-agent.runtime-broker.state-directory` from many places: the variable the server's `application.yml` maps, `QWEN_MANAGED_AGENT_RUNTIME_STATE_DIRECTORY`; every configuration file in Spring's default locations and the launcher's `SPRING_CONFIG_ADDITIONAL_LOCATION`; the files an import or a profile brings in; `SPRING_APPLICATION_JSON`; system properties; command-line arguments; and every relaxed spelling of the property. Earlier rounds of this command read that list itself and refused on what it recognized, and each round found a source it missed. Its configuration resolution has no closed list, so the command no longer reads it.

It starts no context, logs nothing and opens no connection.
 
-The command runs it through `systemd-run` as the control-plane unit runs the server: the unit's account, working directory, environment files and `Environment=` assignments, the `java` on the unit's `PATH`, and the launcher's one default, `config/application.yml` when `SPRING_CONFIG_ADDITIONAL_LOCATION` is unset or empty. It runs this release's jar, copied where the service account can read it wherever the archive was extracted, through `PropertiesLauncher` with `loader.main`, so an older jar without the class fails rather than starting a server. `verify`, which runs after `install`, uses the installed jar and reads the auth mode from the same output. The admin launcher runs the same class as `resolved-configuration`, for the manual procedure on other layouts.

The admin launcher runs the same class as `resolved-configuration`, for the manual procedure on other layouts.
 
 Two cases stay with the operator. The jar can fail to resolve the configuration, as when an import names a missing file, which the server would refuse too. And `systemctl show` prints `ExecStart` arguments joined by spaces, unquoted, so the command cannot pass on arguments the unit gives the launcher. In either case `backup` refuses until `--runtime-state <directory>` names the directory, or `--runtime-state none` declares a deployment that keeps no Runtime state. A backup without the Runtime state the database refers to cannot be restored consistently, so a backup that silently left it out would be worse than a refusal. When the configuration names no directory, as on a deployment without the tool path, `backup` archives none and prints that.
 
+### Listener URLs
+
+`start` waits for the Harness's port and for the control plane's health endpoint, and `verify` probes that endpoint and reads the API. Each address can be set where `server.env` does not show it: `server.port` in `config/application.yml`, a relaxed `SERVER_ADDRESS`, an argument, or a `management.server.port` that moves the actuator to a listener of its own. Read from `server.env` alone, `start` would wait out `--timeout` on a port nothing serves. So both phases take the URLs from the same `ResolvedConfiguration` output:
+
+- **Control plane:** the address `server.address` binds, the port `server.port` binds and `https` when `server.ssl` is enabled. A wildcard bind is reached on the loopback interface of its family, and any other address as bound.
+- **Health endpoint:** Spring Boot's rules for the management port (`ManagementPortType`). Unset or equal to the server's port, it shares the server's listener. A negative one turns the HTTP endpoints off. Any other one opens a listener on `management.server.address`, which binds every interface when unset, under `management.server.base-path`, keeping the server's TLS unless `management.server.ssl` replaces it. `management.endpoints.web.base-path` and the `health` path mapping apply either way, and a blank mapping keeps the name `health`, as Spring Boot ignores it.
+- **Harness:** `qwen.managed-agent.harness.base-url`, the URL the control plane dials, and the preflight's verdict on it: whether its harness row takes the value, untrimmed, as the Harness origin, or `skip` with the Harness disabled, where nothing reads it.
+
+Each phase checks the URLs it dials: both probe the health endpoint, and only `verify --tenant` reads the API, and only when its session row would: the auth mode is `open`, and an `--actor` has a trusted actor header to go in. A phase refuses only over those. A port of 0, picked at start, or a negative one leaves no URL to wait on, so the phase refuses until `--server-url` names one. It refuses as well a URL `fetch` refuses to dial, rather than wait out `--timeout` on probes that cannot be sent: a link-local IPv6 address, which keeps a zone no URL can carry; a port the Fetch standard blocks, such as 6000; and, from `--server-url`, a URL other than `http` or `https`, such as `proxy.test:8443`, or one with a user name or password. A `--server-url` with a query or a fragment is refused too, since the `/actuator/health` and API paths are appended to it and would land in either, and so is one with an `@` left after the URL parser has read no user information: that can be the rest of a password that starts with digits, as in `https://svc:12/[email protected]`, which the parser reads as host `svc` and port `12`, so dialling it would reach the wrong host and naming it would print the password. Such an `@` cannot be told from one a path holds, so a path with an `@` is refused too, and is written with `%40` instead. The value is judged as given before the paths are appended: `https:`, which `--server-url "https://$HOST"` leaves with `HOST` unset, is no URL, though `https:/actuator/health` parses, as host `actuator`. `check` judges `--server-url` the same way, since its plan repeats the option. `start` waits for the Harness at its URL, so it refuses one that is not `http` or `https`: an opaque value such as `proxy.test:8443` names no host to wait on at all. Past that, it refuses a Harness URL the server's Harness connector would refuse, on the server's own verdict, which its configuration reader passes on: the preflight and the connector read the value untrimmed as `java.net.URI` does and take only an `http` or `https` URL with a host and without user information, a query or a fragment, so user information, a query, a fragment, a host with an underscore, an empty user name or a padded value is refused before the Harness restarts, and the refusal names a reason only where the value shows one the server gives too: a user name or password, a query or a fragment, or an `@` in an authority, which `java.net.URI` reads after `//` up to a `/`, `?` or `#`. With the Harness disabled nothing reads the value, so nothing more is asked of it. Pooled, the preflight skips its harness row before it reads the value, but each pool member's connector checks it by the same rule, and the pool drops a member whose connector refuses it, so it is judged all the same. When the configuration does not resolve there is no verdict, so `start` takes only a plain `http` or `https` URL, a rule of its own and narrower than the server's: a host name as `java.net.URI` reads one, whose last label starts with a letter unless it is the only one, with or without the final dot of a fully qualified name, a dotted-quad IPv4 address or a bracketed IPv6 one, which may end in an IPv4 address as `::ffff:127.0.0.1` does, an optional port, which may be empty, and a path of the characters a URI path holds, a `%` only as the start of an escape such as `%20`, read untrimmed. Of the forms `java.net.URI` reads as a host, it refuses only those the URL parser `fetch` uses reads as another address: a name of one label that parser reads as a number, of digits, as it reads `1234` as `0.0.4.210`, or of `0x` and hex digits, and an octet with a leading zero, which it reads as octal, as `010.0.0.1` is `8.0.0.1`. A name of one label such as `4harness`, which a container may have, is taken. A disabled Harness's value may then be refused for nothing, but letting it through could start a pool that accepts no Session. The preflight judges the rest, such as whether the Harness answers. A refusal or a report row prints a URL with its user information as `***`, whether or not the URL parses, `start`'s three outcomes and `verify`'s health row included: everything up to its last `@` shows as `***`, since a password may hold a `/`, `?` or `#` that ends the authority early, and one that starts with digits then even parses, as a port, with the rest of it in the path, the query or the fragment (`http://svc:2024#Secret@harness:4170`). A probe that is sent and still fails is named: `start`'s timeout and `verify`'s health row say what the endpoint last answered, such as `HTTP 503, status DOWN` or `self-signed certificate`, with each control character in that text shown as `�` and the text cut at 200 code points, so an endpoint can neither move the cursor, split the row nor scroll the report away. A status that is no string is shown as its JSON, or as `[unprintable]` when it is nested too deep to write out, and an empty one as `""`: `0`, `false` and an empty string are statuses too, and onlLine truncated

 有两种情况留给运维处理。一是 jar 无法解析配置，例如 import 指向的文件不存在，这时服务端同样会拒绝启动。二是 `systemctl show` 打印 `ExecStart` 参数时用空格拼接且不加引号，命令无法准确地转交 unit 传给 launcher 的参数。这两种情况下，`backup` 都会拒绝执行，直到 `--runtime-state <目录>` 指明目录，或用 `--runtime-state none` 表示部署不保存 Runtime 状态。缺少数据库所引用的 Runtime 状态的备份无法一致地恢复，因此悄悄漏掉状态的备份比拒绝更糟。配置中没有指定目录时（例如未开启工具路径的部署），`backup` 不归档 Runtime 状态，并打印说明。
 
+### 监听 URL
+
+`start` 等待 Harness 的端口和控制面的健康端点，`verify` 探测该端点并读取 API。这些地址都可能设置在 `server.env` 看不到的地方：`config/application.yml` 中的 `server.port`、relaxed 形式的 `SERVER_ADDRESS`、命令行参数，或者把 actuator 移到独立监听上的 `management.server.port`。只从 `server.env` 推算时，`start` 会在一个无人监听的端口上等满 `--timeout`。因此两个阶段都从同一份 `ResolvedConfiguration` 输出中取得 URL：
+
+- **控制面：** `server.address` 绑定的地址、`server.port` 绑定的端口；启用 `server.ssl` 时用 `https`。通配地址经其地址族的回环接口访问，其他地址按绑定的地址访问。
+- **健康端点：** 遵循 Spring Boot 关于 management 端口的规则（`ManagementPortType`）。未设置或与服务端端口相同时，它与服务端共用监听；为负数时关闭 HTTP 端点；其他值则在 `management.server.address` 上打开独立监听（未设置时绑定所有接口），位于 `management.server.base-path` 之下，并沿用服务端的 TLS，除非 `management.server.ssl` 替换它。两种情况下都应用 `management.endpoints.web.base-path` 和 `health` 的路径映射；路径映射为空白时 Spring Boot 会忽略它，仍使用名称 `health`。
+- **Harness：** `qwen.managed-agent.harness.base-url`，即控制面访问它所用的 URL，以及 preflight 对它的判定：其 harness 行是否把这个未经 trim 的取值当作 Harness origin 接受；Harness 被禁用时判定为 `skip`，此时没有任何地方读取这个值。
+
+每个阶段只检查自己会拨号的 URL：两个阶段都会探测健康端点，只有 `verify --tenant` 会读取 API，而且只在其 session 行确实要读时才读：auth mode 为 `open`，且给了 `--actor` 时服务端配置了可信 actor header。阶段只会因这些 URL 拒绝执行。端口为 0（启动时选取）或负数时没有可等待的 URL，因此该阶段会拒绝执行，直到 `--server-url` 指定一个。`fetch` 会拒绝拨号的 URL，同样会被拒绝，而不是在根本发不出去的探测上等满 `--timeout`：保留了 zone 的 IPv6 链路本地地址（URL 无法携带 zone）、Fetch 标准屏蔽的端口（例如 6000），以及 `--server-url` 给出的非 `http`/`https` URL（例如 `proxy.test:8443`）或带用户名、密码的 URL。带 query 或 fragment 的 `--server-url` 同样会被拒绝，因为 `/actuator/health` 和 API 路径是拼接在它后面的，会落进 query 或 fragment 里；URL 解析器读不出用户信息、却仍带有 `@` 的 `--server-url` 也会被拒绝：它可能是以数字开头的密码的剩余部分，例如 `https://svc:12/[email protected]` 会被解析成主机 `svc`、端口 `12`，拨号会连到错误的主机，打印又会泄露密码。这样的 `@` 与路径里的 `@` 无法区分，因此路径带 `@` 的取值同样会被拒绝，应改写为 `%40`。取值在拼接路径之前先按原样判定：`--server-url "https://$HOST"` 在 `HOST` 未设置时留下的 `https:` 不是 URL，尽管 `https:/actuator/health` 能解析成主机 `actuator`。`check` 以同样的方式判定 `--server-url`，因为它打印的计划会重复这个选项。`start` 要在 Harness URL 上等待 Harness，因此会拒绝不是 `http` 或 `https` 的取值：`proxy.test:8443` 这样的不透明取值根本没有可等待的主机。除此之外，对于服务端 Harness 连接器不接受的 Harness URL，`start` 会在重启 Harness 之前拒绝，依据的是服务端配置解析器转达的服务端自身判定：preflight 和连接器都按 `java.net.URI` 的方式读取未经 trim 的取值，只接受带主机名、且不带用户信息、query 或 fragment 的 `http` 或 `https` URL，因此带用户信息、query、fragment、带下划线的主机名、空用户名或带首尾空白的取值都会在重启 Harness 之前被拒绝；只有当取值本身显示出一个服务端同样会给出的原因时，拒绝提示才会写明：用户名或密码、query 或 fragment，或 authority 中的 `@`（`java.net.URI` 在 `//` 之后读取 authority，直到 `/`、`?` 或 `#`）。Harness 被禁用时没有任何地方读取这个值，因此不再对它提其他要求。启用 pool 时，preflight 的 harness 行在读取该值之前就跳过，但每个 pool 成员的连接器都按同一规则检查它，连接器拒绝的成员会被 pool 丢弃，因此照样要判定。无法解析配置时没有判定，`start` 只接受朴素的 `http` 或 `https` URL，这是命令自己的规则，比服务端的更窄：`java.net.URI` 认可的主机名（最后一个 label 以字母开头，只有一个 label 时除外；完整域名末尾的点可有可无）、点分四段的 IPv4 地址，或带方括号的 IPv6 地址（可以像 `::ffff:127.0.0.1` 那样以 IPv4 地址结尾），可选端口（可以为空），以及只含 URI 路径允许字符的路径，其中 `%` 只能作为 `%20` 这类转义的开头，按未经 trim 的原样读取。在 `java.net.URI` 认作主机的写法中，它只拒绝 `fetch` 所用的 URL 解析器会读成别的地址的写法：该解析器读成数字的单个 label，即全为数字（例如 `1234` 读成 `0.0.4.210`）或 `0x` 加十六进制数字；以及带前导零的 IPv4 段，会被读成八进制（例如 `010.0.0.1` 读成 `8.0.0.1`）。`4harness` 这类以数字开头的单 label 名字（容器可能使用）会被接受。这样，被禁用的 Harness 的取值可能被白白拒绝，但若放行，可能启动一个不接收任何 Session 的 pool。其余情况由 preflight 判定，例如 Harness 是否应答。拒绝提示或报告行打印 URL 时，无论它能否解析，用户信息都显示为 `***`，`start` 的三种结果和 `verify` 的 health 行也不例外：最后一个 `@` 之前的内容全部显示为 `***`，因为密码中可能含有 `/`、`?` 或 `#`，使 authority 提前结束；以数字开头的这类密码甚至能解析成功，被读成端口，其余部分落进路径、query 或 fragment（`http://svc:2024#Secret@harness:4170`）。探测发出后仍失败时，会说明原因：`start` 的超时提示和 `verify` 的 health 行给出健康端点最后一次的应答，例如 `HTTP 503, status DOWN` 或 `self-signed certificate`；应答文本中的控制字符显示为 `�`，文本在 200 个码点处截断，因此端点既无法移动光标、拆开一行，也无法把报告刷出屏幕。不是字符串的 status 显示为它Line truncated
