Summary

Register the existing URL-citation replay regression in both test inventories and document the outbound citation projection introduced by #7573. The decoded-checkpoint contract now distinguishes checkpoint framing from citation repair on OpenAI-operated outbound history. This changes documentation and test registration only.

The branch merges trusted dev@6672cfb4a2b9a1dc72e26ed159c1d70368fe0ca7, preserving #7607's layout size repair and the subsequent test-layout shards. The original runtime fix is already on dev; no runtime reimplementation or file-size limit increase is included.

Verification

Updated head: 5b3b87894cf6e2b0e7e70ae1f0b795f728edafec. Validation ran on the resulting merged tree with official Bun 1.4.4+38afee6c8, a frozen install with lifecycle scripts disabled, private temporary homes, and one CPU/RAM/process-limited workload at a time.

• bun test --isolate tests/responses/responses-url-citation-title-repair.test.ts tests/test-layout.test.ts tests/test-layout-tooling.test.ts tests/ci-workflows/file-size-ratchet.test.ts: 47 pass, 0 fail, 685 assertions. This includes the size gate that failed on the old head.
• bun scripts/structure-ssot.ts --fix and bun scripts/structure-ssot.ts: exit 0; generated index agrees with the manifest.
• bun scripts/privacy-scan.ts: exit 0 (ordinary repository privacy gate).
• git diff --check: exit 0.
• Typecheck (bun node_modules/typescript/bin/tsc --noEmit): incomplete; the enforced 300-second workload deadline killed it (about 1.2 GiB peak; no successful result). Limits were not raised. The Bun dependency wrapper's ignored postinstall was not used.
• Full local suite is deferred because it is disproportionate for this documentation/registration-only patch under this host's limits. Focused citation, inventory and ratchet coverage above passed; replacement-head hosted CI is still required and is not claimed passing.

No live provider request, client-file synchronization, service restart, security scanner, merge, release or deployment was performed. The main dirty checkout and protected runtime configuration were preserved. The push used core.hooksPath=/dev/null; the explicit checks and incomplete typecheck are recorded above.

Checklist

• Scope stays focused and avoids unrelated cleanup.
• Docs or release notes were updated when needed.
• Existing runtime/credential behavior is unchanged; ordinary repository privacy gate passed.

This PR remains Draft pending successful typecheck/current-head CI and review readiness. Previous-head CI results do not qualify the new head.

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

Needs fixes before this can land: refresh onto dev containing #7607, preserve its size repair, obtain passing replacement-head CI, and complete draft readiness. No runtime reimplementation is needed.

Still needed on dev: partial. Runtime repair already landed through #7573 / 9a34e21482, including src/adapters/openai-responses/request-strips.ts:54. Explicit registration and the documentation correction remain absent; the existing broad statement is at structure/transports/responses.md:401.

Exact-head CI at triage time: 139b0c4 — 17 success, 10 skipped; test 2/4 and ci fail in run 39919488485. Failure is layout.json at 2,000 lines. 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.

Carried onto current dev as #7865 with a Co-authored-by trailer for you: the structure doc, manifest entry, responses.md link and test registration, with the dev conflicts (manifest, responses.md, generated index) resolved by keeping both sides. This PR will be closed once #7865 lands.

Landed on dev through the carry #7865 (squash d67fedd) with a Co-authored-by trailer for you. Thank you.
