Shaojin WenandQwen-Coder cf29f90062 fix(ci): route the review/resolve permission gate to the ECS pool (#16482) 
* fix(ci): route the review/resolve permission gate to the ECS pool

The authorize job gates every @qwen-code /review and /resolve command, but its
ECS routing required github.event.pull_request, which issue_comment and
workflow_dispatch payloads do not carry. Every command therefore fell through
to ubuntu-latest, and the gate sat in the hosted queue for hours (PR #15286:
3h10m for a 4-second job) while the ECS pool was idle.

Route issue_comment and workflow_dispatch to the persistent ECS pool, matching
qwen-autofix.yml's route/review-scan pattern for PAT-bearing API-only steps.
authorize runs no agent, checks out nothing, and processes no PR content, so
this does not widen the fork attack surface. PR-payload events keep the
same-repo fork guard; the hosted fallback and ECS kill switch are unchanged.

resolve-pr and publish-resolution stay on hosted by design (ephemerality); this
removes the gate wait only.

* fix(ci): harden the authorize ECS-routing pins and risk docs

Address review feedback on the gate routing change:
- Pin the checkout-free invariant the ECS routing depends on: a uses: step on
  authorize would execute contributor-authored files on the persistent pool
  with CI_BOT_PAT in the step env while the expression pin stayed green (R1-1).
  Scoped to authorize; mutation-witnessed (adding actions/checkout reds it).
- Record the trigger-set widening in the design-doc Risks (both languages):
  issue_comment makes the gate fireable by any GitHub user on a fork PR, and
  the should_review authorization fact is now produced on the shared host and
  consumed downstream without re-deriving (R1-2).
- Correct the precedent wording: route loads only the read-only github.token;
  review-scan is the job that loads CI_DEV_BOT_PAT on the pool.

* fix(ci): harden the shared-pool authorize gate against gh config reroute

Address the round-2 CHANGES_REQUESTED review (R2-1 Critical, R2-2):

R2-1: routing the gate to the persistent ecs-qwen pool moved its CI_BOT_PAT
gh api call onto a host with a shared, writable ~/.config/gh. A co-resident
survivor could plant http_unix_socket there, receive the PAT, and forge the
permission response downstream consumes as should_review. Prepend the same
pins as qwen-autofix.yml's route/review-scan — export GH_HOST=github.com plus
a private, guarded GH_CONFIG_DIR (a failed mktemp exits 1; the gate fails
closed). No `unset GH_TOKEN`: it is this step's only credential. Witnessed
with real gh 2.103.0: the as-written step leaks the PAT to a planted socket
and approves a stranger; the hardened step denies with the socket untouched.

R2-2: extend the checkout-free guard to the run: half — pin the step
inventory to the single permission step and forbid `${{` spliced into any run
body (event values must arrive via env:). Mutation-witnessed: removing the
preamble and adding a run-only second step each red the test.

Also correct the design-doc parity claim (both languages): the exposure
matches review-scan only WITH these gh pins; document the hardening.

* fix(ci): extend the ECS gate routing to triage and harden the gate pins

Two batches, verified together before push:

1. Extend the command-gate routing to qwen-triage.yml's authorize (the
   /triage, /tmux, /verify sibling blind spot): the same issue_comment /
   workflow_dispatch disjuncts, and — because that job has three steps that
   spend CI_BOT_PAT on gh — the same self-contained GH_HOST + guarded
   GH_CONFIG_DIR preamble on each, per the repo's per-step convention. Raise
   the recorded workflow size baseline to match the added hardening.

2. Address round-3 review (R2-2 fix-induced, R3-1): the gate pins tested
   substring presence only. Now evaluate the comment-stripped live lines and
   pin the guarded mktemp form + fail-closed shape, require GH_HOST /
   GH_CONFIG_DIR exported before the first gh api, and forbid executing
   repository code via relative paths or interpreters (the pool cwd is the
   reused $GITHUB_WORKSPACE). Applied to both the review and triage gate
   tests. Mutation-witnessed: an unguarded one-liner, a relocated preamble,
   and an appended `node ./…` line each red the tests.

Tests: qwen-pr-review-workflow.test.js 271, qwen-triage-workflow.test.mjs 131,
ci-runner-routing.test.mjs 103 — all pass; prettier + ESLint clean.

* fix(ci): supply RUNNER_TEMP to the triage gate replay tests; harden the gate pins

R4-1 (Critical): the new ${RUNNER_TEMP} gh-config preamble is the first
RUNNER_TEMP reference in the triage permission step, and three replay
harnesses in scripts/tests/qwen-triage-workflow.test.js execute that body
verbatim without setting RUNNER_TEMP — off-CI (npm run test:scripts) the
fail-closed guard exits 1 before writing should_run. Set RUNNER_TEMP to each
harness's existing mkdtempSync dir (the :1773 precedent); the workflow's
fail-closed guard is unchanged. Verified: the file is red under
`env -u RUNNER_TEMP` before and 203/203 green after; dropping the line reds it
again. (The review named two harnesses; running the full file surfaced a third.)

Also clear the round-4 deferred notes:
- R4-2: the /verify ack comment no longer promises a receipt "even when the
  sandbox lane is backed up" — the gate now also queues with the pool.
- R4-3/R4-4: the triage routing pin is now an exact expression equality, the
  step inventory is pinned, and PAT-bearing steps are identified by env
  GH_TOKEN rather than gh subcommand spelling.
- R3-1: tighten the no-repository-code deny-list (quote boundaries +
  interpreter as a word) so `bash -c './x.sh'` no longer slips past;
  mutation-witnessed in both the review and triage gate tests.

Tests: triage vitest 203 (off-CI), triage .mjs 131, review vitest 271,
ci-runner-routing 103 — all pass; prettier + ESLint clean; size gate green.

* fix(ci): correct the gate-routing narrative; close the round-5 verify gaps

R5-1 / F1 (narrative): the motivating incident is a /resolve, whose
end-to-end latency this PR does not change — resolve-pr stays on
ubuntu-latest, so only the gate wait is removed. State this in both
design-doc languages and the pinning test comment; the saving lands on
/review, /triage, /tmux, /verify (pool-routed downstream). Correct the
"cancelled without ever running" sentence to the run's timeline (resolve-pr
started when the gate finished and was cancelled ~29m36s later).

S1: the no-repository-code deny-list missed absolute-path interpreters
(/usr/bin/node x.js) and versioned Python (python3.11 x.py); widen the regex
(optional path prefix + python[0-9.]*) in both gate tests. Mutation-witnessed:
both previously-surviving mutants now red, clean tree green.

S2: each hardened gh step minted a $RUNNER_TEMP/*gh-config.* dir that nothing
removed; add trap 'rm -rf "$GH_CONFIG_DIR"' EXIT to all four steps (RUNNER_TEMP
survives between jobs on the pool).

S3: record the exact final workflow sizes in .size-baseline.

Tests: triage vitest 203 (off-CI, RUNNER_TEMP unset), review vitest 271,
triage .mjs 131, ci-runner-routing 103 — all pass; prettier + ESLint clean;
size gate green.

* fix(ci): pin the no-repository-code invariant on every triage gate step

The triage gate meta-test applied the relative-path/interpreter denylist only to PAT-bearing steps, so a repository-code execution line added to the credential-free budget step survived the suite (witnessed by mutation). The no-repository-code invariant is a job-wide safety premise of the ECS routing: even a credential-free step that runs a planted file leaves a survivor on the persistent host. Pin it on every step's comment-stripped live lines, and align both design-doc versions with the widened coverage and the witnessed mutation set.

* docs(ci): correct the routing-matrix coverage claim for the triage gate

The validation plan said the triage gate is pinned by the triage meta-test AND the ci-runner-routing matrix, but the matrix never reads either authorize job (it pins the sibling pool jobs). State the actual coverage in both language versions.

# TUNABLE WITHOUT A CODE CHANGE: set the repository variable in
# Settings → Variables. Why the fallback is 60: the fixed 30 was
# measurably clipping the distribution — 22 successful triage jobs
# sampled on 2026-08-09 ran median 5.8m / p90 22.3m / max 29.5m, and
# five substantial PRs (8723, 8726, 8731, 8764, 8801) died at exactly
# the cap, each discarding a full agent run. Triage is advisory, so
# the worst case a longer budget risks is one held runner; a killed
# run wastes the same runner AND the work. The value arrives via the
# authorize job's sanitize step (validated, clamped 10..600 — but
# GitHub-hosted runners hard-cap any job at 360 minutes, so values
# above 360 only take effect on the self-hosted pool): a
# malformed variable in a raw fromJSON(vars.X) would kill this job at
# expression time with no status comment. The || 60 covers the events
# where authorize is skipped (issues, plain-number dispatch) and its
# outputs are empty. Expression-valued timeout-minutes is
# probe-verified on a live runner (see #8731).
timeout-minutes: '${{ fromJSON(needs.authorize.outputs.triage_timeout_minutes || 60) }}'
concurrency:
# GitHub evaluates concurrency before the job `if`, but after `needs`.
# Keep non-runnable PR/comment triggers out of the shared per-number
# group so they cannot cancel or replace an authorized run — including
# bot-created issues runs (#9264): the job `if` skips them, but a run
# left in the shared group would still cancel an in-progress triage of
# the same issue before its own skip is evaluated.

# ── What these settings are, and are NOT ────────────────────────────
# The agent runs under --approval-mode yolo, so every permission
# resolves to auto-approve EXCEPT a `permissions.deny` match, which
# the scheduler errors out before approval mode is consulted.
# `tools.core` additionally filters which tools register at all
# (fail-safe: an unlisted tool like web_fetch/web_search/save_memory
# never loads). No `sandbox` key: the job itself is the container.
#
# ⚠️ A command denylist is NOT a security boundary under yolo, and
# is not treated as one here. It is defense-in-depth against the
# NORMAL failure (the agent running `npm test`/`npx`/a build because
# a prompt implied it) and low-effort injection. It does NOT stop a
# determined prompt-injection: `$(...)` substitution is not reliably
# deny-matchable, and exec can hide in `sed s///e`, env-var
# interpreters, etc. Backtick and `<(` ARE hard-blocked below.
#
# The REAL controls, in order of strength:
# 1. No PR code is ever executed (skill Rules; the agent reads the
# PR only through the API and the base checkout).
# 2. Token isolation: the agent's GH_TOKEN is the job's read-only
# GITHUB_TOKEN; every write is a draft executed by
# publish-triage with the PAT. There is no write credential in
# the agent environment to exfiltrate, and the model key sits
# behind the loopback proxy started in the run step.
# 3. The job container plus the per-run workspace sanitize bound
# persistence on the reusable pool (see "Clean stale agent
# state" and the ownership restores).
# A steered agent can still draft malicious content within triage's
# intended capability (a wrong review, a misleading comment); that
# surface is inherent to the product and reviewed by humans. The
# publisher validates shape, not semantics.
#
# The deny list below backs the skill's no-PR-code rule as a speed
# bump: interpreters/build tools, shells, exec wrappers, network
# binaries, path execution, and the git/gh subcommands that execute
# configured commands or materialize PR code. Prefix match is
# word-boundary ("npm" blocks `npm test`, not `npmx`). It also
# blocks `node`, which structurally prevents the agent from running
# the publisher itself in CI mode.

# Render report.md as MARKDOWN instead of an escaped <pre> dump.
# The report is a curated bilingual document (tables, nested
# <details>, headings); the pre/code embedding displayed it as a
# wall of raw source (#8140's comment was the exhibit). The section
# is wrapped in a collapsed <details> so it still costs one line in
# the conversation but renders as real markdown when opened.
#
# A node sanitizer (not sed) does the escaping so it can tell code
# regions apart from prose. CommonMark does NOT decode entities in
# code spans or fenced blocks — they render literally there — so
# escaping & < > @ unconditionally showed the reader &amp;&amp;,
# &lt;T&gt;, &#64;pkg inside the very commands, generic types, and
# scoped-package paths a verification report is read to copy (the
# #8140 symptom, relocated into code). The security floor now rests
# on four line-independent guarantees:
# 1. in PROSE every < is escaped, then only the structural tags
# the report uses as raw HTML (details/summary) are un-escaped
# back to live tags — no other tag can form in ordinary
# prose, so <img>/<script>/onerror never render there. A
# line-level inHtml flag tracks raw-HTML blocks opened by
# details/summary (at any indent, so list-nested folds
# enter the state too): inside one, neither fence lines
# NOR code spans are code — CommonMark/GitHub reads both
# as literal text in a raw-HTML block — so the sanitizer
# prose-escapes the whole line instead of splitting it
# through proseLine, closing the divergence where GitHub
# saw live HTML the sanitizer treated as inert code.
# & and > are left alone in prose (a decoded entity
# yields text, never markup, and an unescaped > cannot
# open a tag once < is escaped), which keeps &&, ->, and
# blockquotes readable. Code-span parity is a paragraph
# property in CommonMark but a line property here, so a prose
# line carrying an unmatched backtick run makes the rest of the
# paragraph's code/prose split unknowable; the scanner fails
# closed and prose-escapes every line until the next blank line
# (over-escaping is the safe direction — a multi-line code span
# shows its entities literally, inert not live). Outside HTML
# blocks, inside code spans/fences < & @ are left alone: <img>
# and @mentions are inert under a code/pre ancestor, and
# escaping them there only mangles the rendered text;
# 2. the comment-open token is broken EVERYWHERE, prose and code
# alike (<!-- becomes an escaped no-op, the autofix-proven
# neutralizer). The break must stay global: the upsert greps
# the RAW body for the running marker and a fence prints
# verbatim, so a forged marker inside a fence must not survive;
# 3. in prose @ gains a zero-width space (@&#8203;) — renders
# identically, never fires a mention (GitHub decodes &#64;
# back to @ before the mention filter runs, so the entity
# alone was inert; the ZWSP breaks the mention token). A
# mention cannot fire under a code/pre ancestor, so code
# keeps a literal @;
# 4. <details> folds are balanced over PROSE only — a </details>
# quoted in a code span/fence is inert text and is no longer
# counted — surplus closers are dropped (they would otherwise
# close the wrapping fold early) and unclosed opens are closed
# at the end, so a malformed report can neither swallow the
# footer nor escape its wrapper. The flat scanner diverges
# from GitHub's container-aware parser whenever a fence it
# holds open cannot exist in GitHub's view, so two signals
# exit non-zero (emit_report then degrades to the escaped
# fallback rather than guessing): a fence still open at EOF
# (GitHub closes a list-nested fence at the container's end,
# not at EOF), and a non-blank line that dedents below the
# fence opener's indent while it is open — the container
# boundary moved, so GitHub already closed the fence and a
# balancing closer later in the file would otherwise let the
# scanner pass unescaped prose through escCode.
# Accepted tradeoff (named, not accidental): rendering promotes the
# report from inert text to parsed markdown, so [links](…) and
# ![images](…) now render live where emit_block showed them literal.
# report.md is agent output from a sandbox that ran PR code; images
# are camo-proxied (mostly noise) and a phishing link under the bot
# identity is the residual surface. That surface exists only while
# the four guarantees hold, so the fail-closed bails above are what
# keep deferring link defusing defensible; defusing link targets is
# a deliberate follow-up, not done here. Two safe-but-ugly display
# costs are named, not bugs: a code span that opens on one line and
# closes on the next is prose-escaped (the reader sees &lt;T&gt;
# inside it — the #8140 symptom relocated but inert), and escCode
# breaks <!-- to &lt;!\-\- which renders LITERALLY in a fence
# (entities do not decode there), so a fenced comment example shows
# as &lt;!\-\-.
# An OVERSIZED report falls back to emit_block wholesale (cut
# markdown dangles fences/folds), as does any sanitizer failure.
