Summary

Closes #7452.

  • Add opt-in claudeCode.appendOnlyToolLoadingModels for direct Responses destinations verified to support chronological additional_tools. Exact provider/model selectors and bounded provider-qualified trailing-prefix wildcards are supported; absent/empty configuration remains off.

  • Reconstruct successful structured client ToolSearch discovery from the request history and append currently authorized deferred definitions after their first loading result, rather than growing the initial catalog. Preserve schemas, strictness, call/result pairing, and native passthrough. No session cache or inferred tool grants.

  • Apply the rewrite only after routing settles on a direct openai-responses route; a selected combo or policy keeps the original catalog (CodeRabbit finding, fixed in ddf986ff).

  • Keep eager/prior-use tools in the initial catalog; refuse ambiguous IDs/catalogs; never restore revoked tools or accept plain text as authorization. Validate opt-in settings and salvage only the malformed optional field without losing providers.

  • Add focused regression and actual HTTP-boundary coverage, register the suite, and document configuration, unsupported destinations, compatibility-enforcement behavior, and legitimate invalidations.

  • Document the native-routing path for Claude models behind a Responses gateway that also serves GPT. No code change: adapter: "anthropic" with modelAdapters keeping non-Claude models on Responses, plus protocols.rollout.managedMessagesNative.

The related local prototype preserved 99.34% and 99.38% input-token reuse across two live GPT tool-loading events through a Responses gateway. Those are observed examples, not a guarantee for every upstream, and native Claude caching has not been established by that experiment.

Why Claude needs a different fix. The same gateway lifts additional_tools back into Claude's top-level tools, and Claude caches tools before the system prompt, so the opt-in above cannot help Claude models there. Measured on the same gateway with claude-opus-5-5 and a 9,000-token fixture, each stage a separate request:

Path Unchanged tools Request that loads a new tool 3-turn conversation, changing token footer
Translated through Responses 9,802 cached 0 cached 7,642 of 28,733 cached
Native Messages (documented config) 9,025 cached 9,025 cached, 197 written 28,729 of 28,733 cached

On the native path the newly discovered tool was called correctly. These are measured examples on one gateway, not a guarantee for every upstream.

Verification

Maintainer integration verification (head d4501c15c65a51a10b212efe90c4920780ebd4fe)

This head merges current dev (2b5148b12, which contains the 2.94.0 version line 736fa5087c) into the reviewed head ab5d2c90 with no conflicts and no source changes. Checks run on Windows 11, Bun 1.4.4:

Command Result
bun run typecheck PASS
bun run structure:check PASS
bun run privacy:scan PASS
bun test tests/claude-integration/claude-inbound-tool-loading.test.ts tests/claude-integration/claude-tool-loading-destinations.test.ts tests/test-layout.test.ts tests/test-layout-tooling.test.ts tests/adapters/anthropic/anthropic-instance-recovery.test.ts 139 passed, 0 failed
Same set plus claude-messages-endpoint, claude-native-passthrough, messages-native, claude-intercept-settings, protocol-settings, explicit-empty-tool-catalog (on the intermediate merge aff566097) 530 passed, 3 failed

The three failures are all in tests/claude-integration/claude-messages-endpoint.test.ts (Desktop OFF leaves Claude messages and health live returns 409 on this Windows host, and two later tests then hit SPEND_LEDGER_OWNER_HOME_CONFLICT). The same file on unmodified dev 2b5148b12 fails the same way (50 passed, 4 failed), so they are host baseline failures, not regressions from this PR.

Full-suite scope exception: the full bun run test was not run locally. The shared host was under a coordinator-imposed resource limit (one focused test process per lane). This PR changes tests/fixtures/test-layout-expected.json, so PR CI selects the four full Ubuntu shards, which cover the rest of the suite.

Earlier verification

Current-head readiness attestation (45068884)

Marked ready at the author's request after independent exact-head verification: 246 focused tests, TypeScript, structure and privacy checks passed. The current branch is 3 commits behind dev, within the repository's 10-commit readiness allowance, and all five review threads are resolved.

The broader Claude-integration run remains not green: 2,157 passed, 1 skipped and 1 failed; the identical failure reproduces on pristine upstream 0aeaf0cb (2,128 passed, 1 skipped and 1 failed). The full repository-wide suite was not run. The documented scope exception relies on focused coverage, exact-head gates and the upstream comparison; it does not claim all tests passed. Hosted CI still requires maintainer approval and completion before merge.

Independent OrbStack verification of 45068884

Independently rerun on 2026-10-24, using isolated source copies of exact PR head 450688842e8c322bdcae5c6eaba7ec178469267e and pristine upstream 0aeaf0cb6b0a7c2f117d8c75f8fa396cf2ea6e39, in Linux/arm64 containers under OrbStack with Bun 1.4.3. The live proxy and working checkout were not modified. Both integration runs used the same installed dependency trees.

Command/check Result
bun run typecheck PASS, exit 0
bun run structure:check PASS, exit 0
bun run privacy:scan PASS, exit 0
Focused test set below 246 passed, 0 failed, 1,266 assertions; exit 0
bun test tests/claude-integration on PR head 2,157 passed, 1 skipped, 1 failed, 15,821 assertions across 103 files; exit 1
Same Claude-integration suite on pristine upstream 2,128 passed, 1 skipped, 1 failed, 15,701 assertions across 102 files; exit 1

Focused command:

bun test tests/claude-integration/claude-inbound-tool-loading.test.ts tests/claude-integration/claude-inbound-tool-reference.test.ts tests/claude-integration/claude-inbound.test.ts tests/claude-integration/claude-inbound-cache-stabilize.test.ts tests/test-layout.test.ts tests/test-layout-tooling.test.ts tests/ci-workflows/file-size-ratchet.test.ts tests/ci-workflows/structure-ssot.test.ts tests/ci-workflows/repo-hygiene.test.ts

Identical failure on both revisions: tests/claude-integration/claude-messages-endpoint.test.ts:161, test POST /v1/messages?beta=true streams an Anthropic-shaped turn end to end. The logged row.usage.inputTokens assertion expected 12 and received undefined. This failure reproduces on unmodified upstream; the full Claude-integration suite is therefore not green in this environment.

The seven CONNECT/TLS failures described in the separate cloud-container report did not reproduce in this OrbStack run. This run confirms the 246-test focused claim but does not reproduce those cloud failure counts or establish their cause. The one skip is the Windows PowerShell trust-script parsing check.

Not run: the full repository-wide bun run test suite on this head. These local results do not establish successful hosted CI or maintainer approval. Older verification sections below concern earlier heads and are retained as historical evidence.

The exact-head file checks also confirm that scripts/test-layout/layout.json is 1,999 lines, the tool-loading test is registered in layout-adapters.json, and structure/data-planes/inbound-compat.md is 600 lines. Run-owned containers and the downloaded test image were removed afterward.

Final physical-route and documentation corrections

Historical head 8f920cdd integrates upstream dev at 5f7f7db5 and addresses the maintainer's two requested changes:

  • Ingress no longer rewrites the catalog. It carries only metadata-qualified discovery evidence through trusted internal options. Each physical adapter binding in request-transport.ts rechecks the final provider/model, wire, combo/policy provenance, and opt-in, then projects a build-input copy. The original raw body and parsed catalog remain available to fallbacks and retries. Forward-auth builds use the same projection boundary; explicit forced-tool intent is preserved.
  • Two real handleClaudeMessages regressions activate x-openai-subagent: collab_spawn fallback in opposite opt-in directions. Both failed before the fix and pass now. A third covers fallback to Chat with the original catalog retained. Key/forward builds and explicitly forced undiscovered tools are covered as well.
  • Reconcile the existing English third-party ToolSearch prerequisite guidance, the English/Korean tool_reference tables, the Korean explanation, and the configuration comments. Client-executed append-only discovery is a narrow opt-in exception, not server-side search support or a cache-hit guarantee.

Verification on the integrated branch:

  • 143 focused tests passed, 0 failed, across tool loading, tool references, inbound translation and cache stabilization.
  • TypeScript (bun node_modules/typescript/bin/tsc --noEmit), privacy scan, architecture/ownership checks and test-layout checks (27 passed) succeeded.
  • Documentation production build succeeded: 593 pages and 84,789 internal links checked.
  • Completed bun scripts/test.ts --changed=dev on the integrated 8f920cdd tree: 42,051 passed, 116 skipped, 28 failed, 704,646 assertions across 1,934 files (400.64s; exit 1). The 28 failure names match the previously documented cases exactly: lock/contention, service/shim behavior, the client recycle timeout and the root-sensitive unreadable-config case. The focused cache/fallback tests passed. This is not a green broad suite; prior baseline comparisons remain historical evidence, not a fresh full-baseline run for this head. Two earlier test attempts were stopped before integration/hardening and are not counted as completed validation.
  • The local proxy, installed patch, credentials and model settings were not changed by this PR follow-up.

Latest review fixes and validation

On head cd8963a4:

  • Match the opt-in against the settled provider/model identity after alias/default-provider/redirect resolution. A redirected destination cannot inherit permission from the source selector.
  • Keep eligible unused deferred tools out of the initial catalog before discovery as well as after it. Require an eager declared ToolSearch function; preserve forced undiscovered and previously used tools. Plain-text or failed references do not activate a tool.
  • Regression RED: four new prefix/alias cases failed before the fix. Focused Claude translator suites: 138 passed, 0 failed; TypeScript, privacy, structure, layout tests, and the docs production build passed.
  • Live synthetic discovery/call tests passed on seven configured GPT routes (GPT-5.6 Luna/Sol/Terra, GPT-6 Astra/Luna/Sol, GPT-6.1 Sol). Warm-prefix cache reads were preserved on the tool-loading request. GPT-6 Luna initially reported no warm cache with a ~3k fixture; a bounded retry with a ~10k fixture established 9,856 warm cached tokens and preserved all 9,856 when the discovered tool was called. These examples are not universal upstream cache guarantees.
  • The affected-test entry point ran 41,780 tests across 1,906 files: 41,636 passed, 116 skipped, 28 failed (379.38s). Failures remain in the previously documented lock/service/shim/client-lifecycle/permission cases, not the focused cache regressions. The broad run is not green; its environment-sensitive failures remain disclosed for maintainer review. The earlier failure details and baseline comparison remain below as historical evidence.

Executed in an isolated Linux/arm64 OrbStack container; no live credentials or user configuration are used by the repository tests.

  • RED: the new prefix-stability/parser cases fail on unmodified upstream; malformed-setting tests also fail before validation is added.
  • PASS: bun test tests/claude-integration/claude-inbound-tool-loading.test.ts with Bun 1.4.3: 17 passed, 0 failed, including the actual Messages HTTP handler, outgoing Responses body, and returned discovered-tool call.
  • PASS on final head: combined new and adjacent tool-reference suites: 21 passed, 0 failed, 75 assertions. TypeScript also passed on this final head. The independent Claude review identified a vacuous .tools comparison; it now checks context.tools, exact tool membership, preserved schemas, and the discovery flag.
  • PASS: bun node_modules/typescript/bin/tsc --noEmit (equivalent compiler invocation; direct entry avoids the bundled Bun launcher whose postinstall was intentionally not executed).
  • PASS: bun scripts/privacy-scan.ts.
  • PASS: bun scripts/structure-ssot.ts.
  • PASS: bun test tests/test-layout.test.ts tests/test-layout-tooling.test.ts: 27 passed, 0 failed.
  • PASS: documentation production build via bun ./node_modules/astro/bin/astro.mjs build from docs-site/.
  • NOT GREEN: bun scripts/test.ts --changed=dev with Bun 1.4.3 ran 41,668 tests across 1,906 files: 41,523 pass, 116 skip, 29 fail, 1 error (443.23s). Initial toolchain setup failures were corrected before this run. The new cache tests pass. An isolated unmodified origin/dev comparison ran 509 tests across the 9 implicated suites: 457 pass, 24 skip, 28 fail, 1 error. It reproduced 27 distinct failure names from the changed run plus the same GUI-build prerequisite error. The remaining unreadable-config permission case was subsequently checked on both unmodified upstream and this PR head: both fail as root (expected 409, actual 200) and both pass as UID/GID 1000. Root bypasses the fixture's chmod(000) restriction; no source change was needed. This PR does not claim the broad suite is green.

Additional error: tests/server/management-integration-routes.test.ts could not build the GUI because the bundled Bun postinstall was intentionally not run during dependency installation.

- On head `ddf986ff`: Claude inbound suites (tool-loading, tool-reference, inbound, cache-stabilize) **132 passed, 0 failed**; TypeScript, `structure-ssot`, `privacy-scan`, test-layout (27 passed) and the docs build pass. The new combo-route regression test failed before the fix. - Docs for the native-routing path: `bun scripts/structure-ssot.ts`, `bun scripts/privacy-scan.ts` and the docs production build pass on head `7233fe8c` (585 pages, 83,070 internal links checked). - Additional live synthetic Responses check: a forced `lookup` declared only in `additional_tools`, positioned between two parallel tool results, successfully returned the requested function call. Verified on the tested GPT gateway only, not a universal capability claim. - Full cross-platform suite has not been run. Maintainer review and required CI remain necessary before merge.

Review-readiness attestation

Requested ready for review on the current head cd8963a4. The branch is current with the fetched dev tip, and all posted correct Codex/CodeRabbit findings are fixed; all three existing review threads are resolved. Required focused regressions, TypeScript, privacy, structure, test-layout and documentation-build checks passed. Live tool-loading checks passed across seven GPT routes.

Full-suite scope exception: the affected run already exercised 41,780 tests in 1,906 files and retained 28 failures in the documented environment-sensitive areas. The prior pristine-upstream comparison and root/non-root permission checks are recorded above. Repeating the entire cross-platform suite in this local container would not provide the missing platform/service environment. Focused behavior and local gates are attested as passed; the broad run is not claimed green. These limitations remain for maintainer/CI review, not hidden by the ready status.

Checklist

  • Scope stays focused and avoids unrelated cleanup.

Walkthrough

Adds opt-in append-only tool loading for selected Claude Messages-to-Responses routes. Successful structured ToolSearch results can place currently declared deferred tools at their discovery points. Configuration validation, route exclusions, fallback handling, integration tests, and documentation are also updated.

Changes: Claude append-only tool loading

Layer / File(s) Summary
Route selection and configuration
src/types/config.ts, src/claude/inbound-tool-loading.ts, src/config/schema/config-schema.ts, src/config/salvage.ts, structure/config.md
Adds claudeCode.appendOnlyToolLoadingModels with provider-qualified exact or trailing-wildcard selectors. Validation limits the list to 128 entries of up to 512 characters. Invalid values are rejected, and load salvage can remove this setting selectively.
Tool discovery projection
src/server/claude-messages.ts, src/server/responses/core-options.ts, src/server/responses/request-transport.ts, src/claude/inbound-tool-loading.ts, structure/transports/responses.md
Messages replay conditionally passes discovery evidence to the Responses transport. For a matching eligible route, the transport adds currently declared deferred tools after successful structured search results and removes those definitions from the top-level tool list.
Integration coverage and behavior documentation
tests/claude-integration/*, tests/fixtures/test-layout-expected.json, scripts/test-layout/layout-adapters.json, docs-site/src/content/docs/guides/claude-code.md, docs-site/src/content/docs/ko/guides/claude-code.md, structure/data-planes/claude-tool-loading.md, structure/clients/claude-desktop.md, structure/INDEX.md, structure/manifest.json
Tests cover discovery results, configuration, route selection, redirects, fallbacks, and combo exclusions. Documentation describes prerequisites, unchanged behavior for excluded routes, and native Messages routing for gateways that reinsert tools.

Explanation

The PR meets the active coding requirements in [#7452]. src/claude/inbound-tool-loading.ts validates provider-qualified exact and bounded trailing-prefix selectors. It reconstructs only successful structured ToolSearch discovery from request history. It preserves eager, forced, and previously used tools in the initial catalog. It rejects plain text, failed, unknown, revoked, duplicate, and ambiguous references. It preserves schemas and chronological additional_tools placement. src/server/claude-messages.ts carries the original catalog and discovery evidence. src/server/responses/request-transport.ts rechecks the settled physical route before it projects a request copy. The focused HTTP-boundary and regression tests cover route matching, redirects, fallback, combo refusal, parser behavior, authorization limits, and request immutability. The reported 246 focused tests, TypeScript check, structure check, and privacy scan pass. The broader Claude suite has one failure that also occurs on pristine upstream, so that result does not establish a PR-specific unmet requirement.

Full details: Out of Scope Changes check

Explanation

The changes remain within [#7452]. The configuration schema, salvage rule, translation helper, transport projection, and tests implement or protect the requested opt-in append-only discovery behavior. The documentation changes explain supported routes, unsupported destinations, compatibility enforcement, invalidation cases, and native Messages routing without adding native routing behavior. The structure and test-layout changes register and document the implementation. The documented native-routing example is directly related to the issue requirement to avoid rewriting native Anthropic routing. No unrelated production behavior is identified.

80-84: 🎯 Functional Correctness

The forced-tool rejection is refuted. additional_tools definitions are added to loadedToolSpecs and merged with body.tools before tool_choice resolution. The parser does not validate the choice against body.tools alone, so removing the deferred declaration from the top-level array does not establish the claimed 400 response.

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Move the claudeCode.appendOnlyToolLoadingModels paragraph out of "Provider validation ownership".

The new paragraph at Line 433 sits directly under the ## Provider validation ownership heading. That section covers src/config/provider-validation.ts, provider payload checks and Google tool-schema policy. The new paragraph describes a claudeCode client setting, not a provider shape.

Other claudeCode config contracts are under "Config surface", at Lines 122-123 (claudeCode.desktopProfile salvage and claudeCode.cliFirstParty). The new salvage rule extends the same "preserve-the-rest" rule from Line 122. A maintainer who reads the Claude config contracts at Lines 122-123 will not find this one in its current position.

Move the sentence so it follows Line 123. The provider-validation section then describes only provider validation again.

As per coding guidelines, a structure/ doc "states the contract that holds right now, in the present tense, for one subsystem."

The append-only tool-loading opt-in cannot keep Claude prefixes stable on a gateway that lifts additional_tools into top-level tools. Document the existing operator path: adapter anthropic with modelAdapters keeping other models on Responses, plus protocols.rollout.managedMessagesNative.

…Responses route

Selector validation checks only string shape, so a selected combo or policy could rewrite tools before routing and then settle on a destination that flattens additional_tools into initial tools. Move the rewrite after route settlement and require an openai-responses adapter on a non-combo, non-policy route. Addresses the CodeRabbit finding on src/claude/inbound.ts.

…tity

Match the append-only allowlist against the resolved provider/model rather than the inbound alias or redirected source. Keep unused deferred definitions out of the initial catalog before discovery as well as after it, retaining forced and previously used tools. Add regression coverage for provider/model aliases, bare selectors, redirects, and predeclared deferred tools.

Reviewed cd8963a445c429ac75eaf1f99fe40604c5c8630f: 77 focused tests passed independently (new loading suite plus tool-reference/cache stabilization coverage), and the actual hosted workflows now pass on this head. The existing cases do not cover a later subagent reroute.

[P2] src/server/claude-messages.ts:892: apply/recheck the opt-in at the final physical route boundary. The rewrite runs here before handleResponses (line 1119). src/server/responses/request-prepare.ts:947-1023 subsequently applies applySubagentModelFallback and replaces route for a collab_spawn turn. An allowlisted direct primary can therefore hide deferred definitions / inject additional_tools before ending at an unallowlisted or translated fallback. The reverse also misses the selected behavior. Keep the original catalog available until the final route is known and add a real handler regression with an active subagent fallback in both directions. This confirms the current bot finding by inspecting the actual execution order; earlier alias/redirect fixes do not close this path.

Also reconcile the existing third-party ToolSearch guidance and tool_reference table with this opt-in exception (including the affected translated explanation), as the other unresolved thread requests. No cache-hit guarantee or server-side tool-search capability is established by these tests.

Preserve the full original catalog until adapter request construction, then project only for the selected physical Responses destination. Add real collab_spawn fallback regressions in both opt-in directions, a Chat fallback case, and forward-auth coverage. Reconcile English and Korean ToolSearch guidance with the client-executed opt-in exception.

@Ingwannu, both requested changes are addressed in head 8f920cdd: the tool-loading projection is now checked at the final physical adapter boundary, with real subagent-fallback tests in both directions, and the English/Korean ToolSearch guidance is reconciled. The 143 focused tests and local type/documentation checks pass; the broader test limitations remain documented in the PR. Could you re-review the updated changes when available?

Re-reviewed 8f920cdd7ad29a49816c322dbde1f427278976c4. The defects from my previous review are addressed: the original catalog is preserved until the physical adapter is selected, each binding applies the final provider/model opt-in, and real late-subagent fallback tests cover both opt-in directions plus a Chat fallback. The English/Korean prerequisite guidance now qualifies the client-executed ToolSearch exception rather than promising server-side search or native parity.

Independent capped Linux/Bun 1.4.3 run: bun test tests/claude-integration/claude-inbound-tool-loading.test.ts — 29 pass / 0 fail / 120 assertions, including those actual HTTP/physical-fallback paths and the explicit forced-tool control. No live gateway or client call.

I am withdrawing my earlier correctness/documentation change request. I also approved execution of the existing fork PR workflows after checking the complete changed surface, unchanged workflow/manifest/lock/install surfaces, pinned actions and read-only hosted PR lanes. CI execution approval is not technical approval or merge readiness. Keep this Draft until current-head required CI actually succeeds, the two still-unresolved Codex threads are reconciled/resolved against these fixes, and the author readiness contract is met. Project-wide typecheck/full-suite were not executed in this focused local re-review; no upstream cache behavior or gateway capability is certified by these fixtures.

Triage note (2026-10-24, against dev at 2494848).

Needs fixes before this can land: reconcile/resolve both Codex threads against current fixes; refresh onto dev; move its +1 test registration into a shard so current layout.json:1999 stays below 2,000; obtain passing replacement-head CI and complete readiness.

Still needed on dev: yes. Dev retains the existing native-only ToolSearch guidance and eager translated schema behavior (src/types/config.ts:150–158); the proposed option is absent.

Exact-head CI at triage time: 8f920cd — 24 success, 8 skipped, 6 cancelled; test 2/4 and ci fail in run 39850678281 on the 2,000-line layout.json ratchet. lane=all on exact head: n.a.

Please refresh onto current dev when addressing these; heads older than dev need a fresh exact-head CI run before review.

…re docs under budget

Move the claude-inbound-tool-loading.test.ts registration from
scripts/test-layout/layout.json into layout-adapters.json so layout.json
stays under its 2,000-line ratchet (precedent: 03bcf78).

Restore structure/data-planes/inbound-compat.md to upstream dev (600
lines, its budget) and repoint the three links to the removed pointer
section at the dedicated data-planes/claude-tool-loading.md doc.

@Ingwannu, head 45068884 is ready for review again. All review threads are resolved, and independent OrbStack verification confirms 246 focused tests plus TypeScript, structure, and privacy checks pass. The one Claude-integration failure reproduces identically on pristine upstream and remains documented; the full repository-wide suite is not claimed green.

Could you approve the workflows awaiting maintainer action on this head?

Please also re-review the current head when available. The branch is currently 3 commits behind dev, within the readiness allowance.

Re-reviewed 450688842e8c322bdcae5c6eaba7ec178469267e, including the physical-adapter projection and moved test registration. Independent pinned Bun 1.4.4 validation with matching frozen dependencies and private homes:

bun test --isolate tests/claude-integration/claude-inbound-tool-loading.test.ts tests/claude-integration/claude-inbound-tool-reference.test.ts tests/claude-integration/claude-inbound-cache-stabilize.test.ts → 82 pass, 0 fail, 254 assertions.

The real Messages-boundary controls cover resolved aliases/redirects, both late-fallback opt-in directions, fallback onto Chat with the complete original catalog, forced undiscovered tools, and combo exclusion. The original catalog remains available until each physical adapter's build-only decision; the scoped projection has not moved back to pre-routing selection. No live Claude/gateway call or cache-hit guarantee is inferred from these fixtures.

I approved the existing current-head Cross-platform CI and Catalog async contracts fork runs after inspecting all changed paths, workflows and installation surfaces. This is execution approval, not a green result or technical approval. The prior change request remains withdrawn; keep Draft while the current gate's readiness/ancestry checks, review resolutions and exact-head CI are outstanding. This follow-up does not claim a full local suite or an independent local typecheck pass.

Release triage for v2.93.0 (maintainer decision): deferred until after the 2.93.0 release. This PR stays open.

Why: it conflicts with dev, is still a draft, and adds a new opt-in routing/config surface (src/config/schema/config-schema.ts, src/types/config.ts, a new structure data-plane doc) that changes how Claude inbound tool catalogs are replayed on Responses routes. Other open work touches the same tool-catalog and replay paths (#7637, #7308, #7374), so this needs to be reviewed together with them, not squeezed into the release.

To pick it back up: resolve the conflicts on current dev, complete the readiness checklist, get green exact-head CI, and note how it interacts with #7637's additional-tools handling.

Maintainer update for the v2.93.0 cycle: this PR is scheduled to land after v2.93.0 is published on main. It is now a post-release item; the earlier deferral comment is superseded. Until the release ships, it stays unmerged.

I pushed ab5d2c90c3560aad7fa10c0d3a126202e0b304ff to this branch. It merges current dev (no rebase), resolves the conflicts, and keeps your commits and credit. On top of that:

  • Fixed destination exclusions, so incompatible discovery destinations keep their full catalogs.
  • Fixed provider-rename selectors.
  • Added regression tests: 7 of 9 fail before the fixes, and all 9 pass after.
  • Updated the docs and structure notes.

Validation on Windows with Bun 1.4.4: 505 focused tests pass with 0 failures. Typecheck, structure check, privacy scan and docs build pass. Independent review round 1: PASS, with no findings. With the option off, sends are byte-identical to dev.

Remaining before merge: exact-head CI on this push, publication of v2.93.0, and a final recheck against dev at that time. Combined behaviour with #7637 on custom gateways is not tested yet.

Maintainer integration into dev (MAINTAINERS.md, "Review and merge policy": a maintainer with admin access may integrate a PR into dev without another maintainer approval). This is maintainer integration, not an approving review.

Exact head: d4501c15c65a51a10b212efe90c4920780ebd4fe (reviewed head ab5d2c90 plus a no-conflict merge of dev 2b5148b12, which contains the 2.94.0 version line).

Review: the earlier maintainer-lane review passed on ab5d2c90 with no open findings. All review threads are resolved. The dev merge changed no PR source.

Exact-head CI: Cross-platform CI run 40515934306 passed gates, test 1/4 through test 4/4, docker smoke, npm-global ubuntu-latest, docs site build, structure gate, storage policy, api usage and ci. Catalog async contracts run 40515934469 passed. macOS and Windows jobs are skipped on pull requests by policy.

Combined with current dev: dev moved four commits after this head. git merge-tree reports no conflict. On the local merge of this head with dev 1fe3dd758, the layout guards plus the two tool-loading suites passed (73 passed, 0 failed), and structure:check passed.

Re-checked against dev d9f594b01 just before merging: still no conflict, and the layout guards pass on the local merge (29 passed, 0 failed).

Gate status: enforce-target passed on this exact head (run 40515931109). A second evaluation started by the ready-for-review event (run 40518829506) has sat in the Actions queue for over 40 minutes. The dev ruleset has no required status checks.

Local verification and scope exception: see the "Maintainer integration verification" section in the description.
