The loop limit matrix now includes allowedTools: ["advisor", "web_search"]. Advisor-only choices are labeled as direct-loop controls that the planner rejects. The actual handleResponses regression also runs the wire allowed_tools choice and verifies that both tools reach the worker, 5 worker legs end in advisor_continuation_limit, and the identical-question fixture makes exactly 1 expert request through the existing runtime deduplication. The distinct-question loop fixture retains its 3 consultation attempts, 5 billed legs and usage assertions.
Windows Bun1.4.4: both related files pass 73 cases / 529 assertions, typecheck 2,252 source files, structure/privacy/file-size gates pass. Independent read-only review found no blocker. An initial expectation of 3 real expert requests was corrected after inspecting the existing same-focus deduplication contract; the final exact-1 assertion strengthens the previous upper-bound check. Only two test files changed. Exact-head fork CI41133542875/Catalog41133542729 and upstream CI41133543904/Catalog41133543893 succeeded. All upstream required checks pass and the new review thread is resolved. Previous-head CI below is historical. Duri continues to own upstream lidge-jun#8018 CI, body and Ready metadata.
Motivation
Address a security bypass where a fetch-based web-search turn could install and run the synthetic advisor tool even when the request's tool_choice/allowed_tools excluded Advisor, allowing undeclared worker-emitted advisor calls to trigger consultations.
Description
Gate synthetic Advisor presence in fetch-based web-search turns by evaluating the request's effective tool-choice predicate with toolChoiceToolPredicate before installing the Advisor sidecar step and appending its synthetic tool to parsed.context.tools in src/server/responses/sidecar-execution.ts.
Stop widening the advertised tool catalog: compute requestedTools = parsed.context.tools ?? [] and only add the Advisor tool when advisorAllowed is true, using toolChoiceToolPredicate(parsed.options.toolChoice, [...requestedTools, advisorPlan.tool])(advisorPlan.tool).
Add an end-to-end regression in tests/advisor/advisor-responses-wiring.test.ts that exercises a tool_choice of allowed_tools permitting only web_search, asserting the worker-dispatched catalog contains only web_search and that no Advisor consultation is performed; also extend the test helper workerRequest to accept tool_choice payloads.
Update structure/advisor.md to document that fetch-based web-search Advisor injection and interception respect the per-request tool_choice and cannot be widened from a web_search-only grant.
Current recovery follow-up at fa28a09ff90a486c73d94e3fe2b8b0ca82edb5c6
Synthetic Advisor permission is now evaluated for the dispatched iteration. Tools-disabled empty-answer recovery revokes that permission even when the original turn installed a sidecar. Ordinary exhausted-Advisor iterations preserve their paired limit handling under the effective tool choice. The synthetic recovery case reproduced 7 requests instead of 3 before the fix; both synthetic and client-Advisor recovery controls now pass. Four limit choices preserve 3 consultations, 5 billed worker legs and exactly-once usage.
Windows Bun1.4.4: 115 Advisor cases / 671 assertions, typecheck (2,252 source files), structure/privacy/file-size gates and docs (633 pages / 91,435 internal links) passed. A final test-only type annotation was separately verified with 10 cases / 66 assertions. Independent read-only review found no blocking issue. Exact-head fork CI41126778077/Catalog41126778011 and upstream lidge-jun#8018 CI41126773636/Catalog41126773677 succeeded. All upstream required checks pass and the follow-up review thread is resolved. Upstream lidge-jun#8018 uses this same branch; Duri remains responsible for upstream CI, body and Ready metadata. Historical validation below is not carried forward as current-head CI.
Earlier follow-up at c101c91920af85cc90158bd432b680afd4d29bf4
Integrated current dev 3cab4a74 and closed the review gap in client delivery. Without an active Advisor sidecar, the search scanner now rejects an unauthorized advisor call before its ID or arguments reach the client, including partial calls. Ordinary client-declared advisor tools retain passthrough only when the current iteration permits them. Tools-disabled empty-answer recovery cannot reuse an earlier declaration, and refusal accounting includes every billed leg once.
The original response test now asserts failure and absence of the excluded call. New allowed/excluded client-tool controls, complete/incomplete/unterminated scanner cases, and a search-to-empty-answer-recovery case cover the boundary. The targeted pre-fix run reproduced 5 fail / 1 pass. Final local validation on Windows with pinned Bun1.4.4 and isolated homes: 111 Advisor cases / 643 assertions, 136 search/usage/refusal/Anthropic cases / 556 assertions, typecheck 2,252 files, structure/privacy/file-size checks, and docs build 633 pages / 91,435 links all pass. Independent read-only review found no blocker. Exact-head Cross-platform CI41114987815 and Catalog41114987867 succeeded; all required checks pass and no unresolved review threads remain. Earlier-head results below are historical evidence only. Ready does not imply maintainer/security acceptance or merge.
Original implementation testing
Ran ./node_modules/.bin/bun test tests/advisor/advisor-responses-wiring.test.ts and all tests passed (56 pass, 0 fail).
Ran ./node_modules/.bin/bun test tests/ci-workflows/file-size-ratchet.test.ts and it passed (9 pass, 0 fail).
Ran type checks and repository invariant checks with ./node_modules/.bin/bun run typecheck and ./node_modules/.bin/bun run structure:check, both succeeded with no type or structure errors.
Ran ./node_modules/.bin/bun run privacy:scan which passed, and verified git diff --check returned clean.

English plus all seven existing translated Advisor guides now explain the effective tool_choice / allowed_tools condition. Frozen dependency installation and final docs build passed: 625 pages, 90,472 internal links; generated HTML was checked for the qualification on all eight pages. ASTRO_TELEMETRY_DISABLED=1 avoided an environment-only telemetry configuration write; no site/product setting changed. Product source and existing regression remain unchanged from the original successful CI at 556f8519afa792c024fc0c0d99e2fdfb35d26480. Hosted Cross-platform CI 41009404685 now succeeds on this exact HEAD. The first attempt had one existing Reserve-ingress fixture bind collision (EADDRINUSE); the unchanged focused file passed 32 cases / 772 assertions, and one retry of only failed jobs succeeded (test changed 123915547047, aggregate 123917371055). The first failure and source-identity evidence remain recorded. Catalog also passed. Devin resolved the original documentation finding; final approval remains separate. Windows/macOS policy skips are not execution evidence.
Clarified that manual Advisor consultations during fetch-based web search are available only when the effective tool choice permits them. Restricting allowed tools to web search—or enabling hosted search—does not grant Advisor access.

Walkthrough
The fetch-based web-search sidecar now exposes and intercepts the synthetic Advisor tool only when the effective tool_choice permits it. A regression test and documentation updates cover the restriction, including the case where only web_search is allowed.
The sidecar checks whether tool_choice permits the synthetic Advisor tool. The regression test verifies that a request requiring only web_search does not dispatch Advisor. The reference documentation describes the rule in English and translated versions.
Turns that restrict tool choice to web search can still forward a model-emitted advisor call to the client, so the restriction is not fully enforced. Reject that call when Advisor is inactive and add a response assertion to the regression test before merging.

Explanation
The title "fix(advisor): honor web-search tool choice scope" matches the main change. The PR makes fetch-based web-search turns evaluate the effective tool_choice before adding the synthetic Advisor tool or sidecar step. The raw summary confirms this for sidecar-execution.ts, the advisor docs, and the wiring test. The title is specific and concise, and it names the affected component (advisor) and the behavior change (tool choice scope).

Taking ownership of the requested remaining review/test follow-up at 556f8519afa792c024fc0c0d99e2fdfb35d26480, after #796/#798/#799. Scope: verify the Advisor tool-choice contract and update the affected public/translated guide claims, preserving the existing tool authority predicate. The original linked Codex Task and commit remain the handoff source.
Current remote head, reviews, CI, and visible activity are being checked in isolated workspaces. The old task's unpublished workspace is not accessible from this session, so I am not claiming that it is idle or empty. Any publication will preserve the current commit ancestry and re-check the remote head before a normal fast-forward update. These PRs stay separate; this ACK does not authorize a merge, force push, installed-app replacement, or security/permission setting change.
CI follow-up for current HEAD f78fc64b3a8042a1aad7b19f46eae400de552107 (updated 2026-10-30 05:57 UTC):
Attempt 1 / test changed checked out 802964a320d998501ed8ac0933b2ad65411a5012 (this HEAD + dev 3ea89653) on Bun 1.4.4. It reported 18,040 pass / 39 skip / 1 fail. The sole failure was Reserve eligibility trusts receiving-listener admission > spoofed Host/forwarded headers and body admission/proof fields cannot select ingress.
The failure was EADDRINUSE on port 41779 while reserve-ingress-fixture.ts called startServer, before the case's ingress assertions. The port probe is closed before the fixture binds the real listener, leaving a possible bind race.
The fixture, test, src/server/ports.ts, and src/server/index.ts have identical Git blob IDs in dev, the original PR HEAD, this HEAD, and the CI merge commit. No fixture or production change was added for this result.
I ran the unchanged reserve-ingress.test.ts once with native Linux Bun 1.4.4 and normal repository preload/queue safeguards: 32 pass / 0 fail / 772 assertions, including the exact case above (3.23 s). This is separate focused evidence.
The first failure remains part of the record; this retry does not establish that the existing fixture's port-selection race has been eliminated. No concurrency guard, permission, security setting, or Windows policy was changed. Conditional Windows/macOS skips are unexecuted.
