Summary

Closes #7307. Running Codex tools can outlive Anthropic's short cache TTL; image pressure can repeatedly change old image bytes or stop a turn instead of compacting complete old context.

confirmed five-minute prefix + verified running own turn → optional renewal at 270s
ended / unknown / expired → stop
26 MiB image base64 / final JSON limit / recoverable image 413
  → summarize complete old units once → keep newest image unit → continue same turn

• Keep compatible tool/system/history prefixes and stable historical image bytes across append/retry. Generic reasoning replay identity and signature-rejection memo behavior stay identical to dev; renewal and image checkpoints use their own request-owner evidence.
• Add anthropicCacheRenewal, default off, only for compatible five-minute requests on verified running main/child turns. Natural confirmations replace the timer. Bounded retries stay inside confirmed lifetime. Explicit retention and dev's first-party one-hour default remain authoritative. Configured root/identity/pool token ceilings disable detached renewal.
• At 26 MiB of image base64 or 32,000,000 bytes of final JSON, compact complete old units under verified ownership and reuse the checkpoint. The shared native Messages allowance is also 26 MiB; its existing image tiers and other processing remain unchanged.
• An upstream image 413 with compactable old images can perform one bounded compaction/retry on direct, search and media paths. Release the refused response before summarizing; share the original send budget and cancellation. Repeated 413, image-free requests, unverified ownership, exhausted budget or an oversized newest unit do not trigger repeated summaries or degraded historical uploads.
• Preserve tools/system during routed summaries, bypass sidecar execution and reject summary client-tool output before publication. Hosted tools use tool_choice: none, accepting that cache tradeoff.

No native Codex patch, installed-runtime change, default background spend, credential migration or CI policy change. Image work reimplements and extends closed, unmerged #4549; attribution is retained below and in branch history.

Evidence

Contract	Before / after	Boundary
Running-state renewal	Offline real-shape large lifecycle records and entry tests cover main/child ownership, 270s renewal, natural replacement, ended/unknown/expired states, cancellation and bounded retries. Disabled mode starts no watcher or renewal.	Provider zero-output support, credential ownership and actual savings still require maintainer acceptance. Cancellation after a committed send is not zero cost.
Stable prefixes	Existing compaction tool-prefix assertion fails on unchanged dev and passes here. Prefix/image tests cover stable bytes, tool/system retention and compatible breakpoints.	Necessary compaction makes a new prefix; this does not promise a provider hit on that new prefix.
Image pressure and continuation	Four focused upstream-image-413 fixtures failed before this correction. The full entry suite now passes 88/88, including direct/search/media recovery with renewal off/on, streaming/non-streaming, a one-slot pacing lease, newest-image retention and checkpoint replay.	One forced recovery only. Repeated refusal, text-only input, cancellation, invalid summary, exhausted budget and irreducible newest context are checked separately.
Unrelated original behavior	8 generic replay/rejection source, documentation and test files are byte-identical to integrated dev. The previous scope-cleanup head passed 299/299 original replay/signature/native compaction/module tests; those historical receipts are not new-head reruns.	The added generic replay-identity migration and its parent-compatibility/memo follow-ups are withdrawn. Two tests introduced by that withdrawn branch were removed with it; dev's original assertions are restored unchanged.

All fixtures are synthetic and offline. No production conversation, screenshot, credential or raw usage log is committed; no paid model request was used. Historical unattributed low-hit requests remain unattributed. Rare-scenario natural acceptance is not claimed.

Verification

Current candidate: db134eedde9b7be1e0eb9101d35d0950a44a1d0a, integrated with dev 880127dbd356c720779222a14a97c11adc8cf881. The latest merge only required retaining both entries in the test layout's shard roster: upstream's chat shard and this PR's cache-lifecycle shard. The preceding integration retained both sides of an independent test-fixture registration conflict. No manual business-code conflict resolution or new behavior was added. The PR's changed-path set remains the same 62 files; all eight withdrawn-branch files are byte-identical to the new dev, and the image allowance remains 26 MiB.

Current-head hosted validation passed: original, unchanged release-gates run 39869279388 completed successfully on this exact head, with 18 successful executed jobs, including all three macOS test shards. Eight lane exclusions/skips are not counted as passes. The preceding candidate's run 39846557249 remains historical evidence. Fork success does not replace required upstream CI or owner review.

Observed dev c51b0b4 is 13 commits ahead of integrated baseline 880127d. The recent-dev readiness item is unchecked until an applicable readiness/integration update. The validated PR head stays fixed; dev drift does not reopen candidate publication or trigger another moving-tip merge. Any remaining integration conflict is tracked separately; Draft and the maintainer's independent review hold remain in force.

Historical receipts: prior merge e1c3c00 passed 303 focused local tests; its two hosted attempts failed because the three macOS shards were not acquired by hosted runners, not because a test executed and failed. Scope-cleanup head 259c87d passed 648 local tests and the original fork release-gates run 39721934382, with 22 successful executed jobs. Untouched earlier integrated dev passed run 39710015787. These remain history, not additional current-merge runs.

Full-suite exception (AGENTS.md, Commands): local full-suite success is not claimed. An earlier broad Windows run stopped at 900 seconds (exit 124); the changed-mode attempt reported its merge base but produced no terminal summary after more than five minutes. Current focused tests use the documented resource exception; broader coverage is delegated to exact-head hosted CI. Lane exclusions/skips are not counted as passes; full Windows shards and macOS-control were not requested. Live natural acceptance and independent combined lifecycle/retention owner review remain outstanding.

Merge Danger

Door: two-way. Revert the feature commits; no transcript or configuration migration is required.

Blast Radius: Anthropic and shared Responses observation/provenance. Renewals and summaries may be billed. Reliable IPC is required; the local writer-lock fallback supports Windows and fails closed elsewhere. Credential-pinned detached transport, hosted-tool prohibition, summary persistence, final byte limits and newest-image semantics need explicit security/runtime acceptance.

The PR remains Draft under the maintainer's explicit intake. Current fork validation and old-head review receipts do not waive that hold or approve the whole PR.

Checklist

• Scope stays focused and avoids unrelated cleanup.
• Docs or release notes were updated when needed.
• Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Privacy checks passed; security acceptance remains a maintainer action.

📝 Walkthrough

The change adds opt-in Anthropic cache renewal for verified Codex turns, stable image encoding, and local image-history compaction when request limits are reached. It also adds request-origin diagnostics, Codex runtime checks, and tests and documentation for these changes.

Changes: Anthropic Cache Lifecycle

IPC state and rollout-file records report whether a matching turn is active. The Windows writer-lock check and tests cover runtime-state validation.
Cache renewal and request diagnostics src/anthropic/*, src/lib/anthropic-cache-observation.ts, src/server/request-origin.ts, src/server/request-log.ts, src/server/request-log-conversation.ts, src/server/responses/fetch-helpers.ts, src/server/responses/adapter-dispatch.ts, src/server/responses/adapter-continuation.ts, src/adapters/anthropic.ts, src/config/schema/config-schema.ts, src/types/config.ts, src/web-search/progress-stream.ts, src/lib/response-body-inactivity.ts, tests/adapters/anthropic/anthropic-cache-renewal.test.ts, tests/responses/responses-anthropic-cache-lifecycle-entry.test.ts, tests/responses/responses-anthropic-cache-prefix.test.ts, tests/usage/request-log-conversation.test.ts, tests/helpers/anthropic-renewal-clock.ts, docs-site/src/content/docs/reference/configuration.md, structure/*	The default-off setting gates renewal. Valid usage confirms a cache snapshot, and the manager schedules bounded renewal attempts while the Codex turn remains active. Response wrappers preserve usage observation. Request-origin records capture sanitized metadata; tests cover timing, eligibility, identity, and logging.
Stable Anthropic image encoding and wire limits src/adapters/anthropic-image-normalize.ts, src/adapters/anthropic-image-guard.ts, src/adapters/anthropic.ts, tests/adapters/anthropic/anthropic-image-*, tests/adapters/abort-race.test.ts, tests/providers/github-copilot/github-copilot-account-origin.test.ts, structure/providers-and-adapters.md, structure/providers/anthropic-cache-lifecycle.md	Anthropic image encoding no longer varies with image age, retry bias, or aggregate pressure. The adapter checks image count, dimensions, aggregate base64 size, and serialized request size. Updated tests expect upstream 413 responses without lossy image retries.
Image-history compaction and prefix-preserving summaries src/server/responses/anthropic-image-context.ts, src/server/responses/image-context-recovery.ts, src/server/responses/sidecar-execution.ts, src/server/responses/request-sidecar-auth.ts, src/server/responses/response-effects.ts, src/server/responses/adapter-delivery.ts, src/server/responses/adapter-dispatch.ts, src/server/responses/core-pipeline.ts, src/server/responses/compact.ts, src/server/responses/sidecar-tool-surface.ts, src/responses/compaction-summary.ts, src/types/request.ts, tests/responses/responses-anthropic-cache-prefix.test.ts, structure/transports/*, structure/providers/anthropic-cache-lifecycle.md	When image limits require recovery, Responses handling summarizes an eligible older prefix at complete tool boundaries, validates the result, and checkpoints it for reuse. Anthropic routed compaction preserves its tool and system prefix, and summary output is rejected when it is empty, incomplete, or attempts tools.

Merge Risk: 🟡 Moderate · up to 7e2f8

Image-heavy Anthropic conversations sent through Chat Completions, Messages, or clients without a thread ID now fail with 413 instead of dropping old images and continuing. When opt-in cache renewal is enabled, non-streaming turns that need a continuation can fail to parse. Renewal requests are also not counted against configured spend ceilings. Fix the image fallback and continuation parsing before merging.

Explanation

The PR addresses the coding requirements in #7307. src/server/responses/response-effects.ts preserves the Anthropic compaction tool and system prefix and sets toolChoice to none for hosted server tools. src/responses/compaction-summary.ts and the referenced delivery path reject tool attempts and invalid summaries. src/server/responses/anthropic-image-context.ts tests the serialized request limit, compacts only complete old units, retains the newest unit, binds checkpoints to the provider owner, and reuses valid checkpoints. src/adapters/anthropic-image-normalize.ts and src/adapters/anthropic-image-guard.ts preserve image bytes and perform non-mutating limit checks. src/anthropic/cache-renewal.ts, src/anthropic/cache-renewal-runtime.ts, and the Codex runtime-state modules implement default-off, owner-bound renewal with five-minute expiry, running-turn checks, and stop handling for ended or unknown turns. The listed focused tests cover these behaviors, and the reported typecheck passed.

Full details: Out of Scope Changes check

Explanation

Most changes support #7307, including request-origin diagnostics, own-thread identity, cache observation propagation, structure documentation, and focused regression tests. However, structure/transports/responses.md also changes the /v1/* routing documentation to state that unknown paths return JSON 404 errors instead of falling through to GUI static serving. The routing behavior is not connected to cache-prefix preservation, image compaction, or running-turn renewal. This is a demonstrated unrelated documentation change.

Resolution

Remove the unrelated unknown-path routing documentation change from structure/transports/responses.md. Keep the Anthropic cache-lifecycle documentation in that file.

Full details: Docstring Coverage

Explanation

Docstring coverage is 33.33% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 69 functions across 47 files. (9 skipped: 9 unsupported.)

Write docstrings for the functions missing them to satisfy the coverage threshold.

[Ingwannu]

Intake at 14c961c6b2; #7307 remains open. Please make prefix preservation independently reviewable from opt-in renewal and automatic in-flight image summarization. They have different acceptance boundaries: an unchanged sent prefix must survive ordinary compaction/image handling even with renewal disabled; renewal needs exact running-turn ownership, no request after ended/unknown state, cancellation and a stated upstream/cost contract; recovery must preserve complete call/result units and newest image semantics under the final serialized-byte limit. The shared request-origin/runtime-state and transport changes make this more than a cache-marker patch. Keep Draft while owner/runtime review and exact-head functional CI are outstanding. I did not run real turns, synthetic renewals, scans or modify client transcripts.

[S0RYUASUKA]

The managed readiness checklist is now complete on 7e2f8cf; the repository gate marked this PR Ready for Review and added review-ready.

The follow-up changes tests only: own-thread identity in recovery fixtures (including a parent-only non-sharing check), expectations for no lossy 413 retry, and asynchronous fixture teardown. The directly related groups pass 107 + 140 tests, with typecheck, privacy and file-size checks passing. The description retains the full scope exception: the broad Windows import-graph run hit 900 seconds / exit 124 and is not claimed green.

Remaining maintainer actions before merge:

1. Approve the current-head fork workflow runs: Cross-platform CI, Catalog async contracts, and React Doctor currently report action_required. My account has no repository write/maintain permission.
2. Review the credential-pinned, default-off renewal transport and hosted-tool prohibition. The security-review checkbox remains open for that review; Ready does not imply security approval or merge approval.

No live paid model requests were used for validation.

🚀 Performance & Scalability | 🟡 Minor | ⚡ Quick win

The continuation loop still runs the Anthropic image-tier retry, so each 413 continuation is resent once unchanged.

• This PR turned off the Anthropic image-tier retry in the main recovery loop: adapter-dispatch.ts Line 1759 now checks transportState.activeAdapter.name !== "anthropic".
• It also stopped passing imageTierBias to normalizeAnthropicImages (src/adapters/anthropic.ts Lines 1034–1036).
• This continuation branch still calls shouldAttemptImageTierRetry, which returns true only for adapterName === "anthropic" (src/server/image-retry.ts Lines 38–41).
• It then sets imageTierBias = 1 and rebuilds. The Anthropic adapter now ignores the bias, so the rebuild is byte-identical to the rejected request.
• Result: every Anthropic 413 continuation re-uploads the same body (up to 32 MB) once before it fails.

Apply the same adapter exclusion here.

I missed your explicit instruction to keep this Draft pending runtime-owner review and exact-head functional CI. Completing the automatic four-box gate did not satisfy that request; I have restored Draft and left the final readiness confirmation unchecked.

I separated the three acceptance contracts in the description and added one directly missing regression receipt: image-count recovery now runs with renewal disabled and enabled. Both modes retain the tool/system prefix and newest image result and reuse the summary checkpoint. Disabled mode additionally advances to 270 seconds and asserts no zero-output request and no runtime watcher. The ordinary compaction prefix test already uses an empty config, independently of renewal.

The updated prefix/lifecycle-entry/native-runtime group passes 90 tests, 0 failures; typecheck, file-size ratchet and diff checks pass. This follow-up changes a test only. Existing byte-stability, ended/unknown/expired-turn, cancellation and retry receipts remain separate; their earlier results are not represented as a fresh full run. The broad Windows run's 900-second timeout and unclassified partial failures remain disclosed.

Current-head fork CI still needs maintainer approval. Could you approve the functional workflows and review the runtime-owner/transport boundary? I will keep Draft until your intake conditions are met or you explicitly accept the focused-validation exception for review. I have not claimed real-provider zero-output support, live acceptance or cost savings, and have not sent paid model validation requests.

[P1] Parse renewal-enabled continuation responses using their actual wire format.

At 62a53c2, src/server/responses/adapter-continuation.ts:293-295 now attaches the natural renewal scope, so src/anthropic/cache-renewal-runtime.ts:100-103 forces eligible upstream requests to SSE. The continuation parser at adapter-continuation.ts:729-734 still selects parseResponse from nextParsed.stream === false; Anthropic's parseResponse reads JSON. A non-stream caller therefore loses a valid continuation when the upstream body is SSE. The initial delivery path already uses the response content type to handle this distinction.

I independently reproduced the existing bot finding using the PR's offline entry harness, with all real connections denied: a non-stream HTTP request, emptyCompletionRetry: true, a function tool (web-search sidecar disabled), an empty first completion and a valid text completion on the second upstream call. With anthropicCacheRenewal: false, two sends produce status: completed and the expected text. Changing only renewal to true still performs two sends but produces status: failed, empty_completion_retry_failed, and no answer. The paired expected-success regression is 1 pass / 1 fail. This is an observed public request failure, not just a parser-shape concern.

Please select continuation parsing from the actual upstream content type/stream contract, preserving the inactivity guard and cache-usage observer, and add this paired entry regression with renewal enabled and disabled. Cover the terminal-guard continuation path using the same parser as well.

The existing four focused lifecycle/prefix/runtime-record files pass independently (139 tests, Bun 1.4.3, Linux, isolated homes and capped cgroup). They do not cover this failure. Full-suite, current-head typecheck and live provider/cross-platform acceptance remain outside this local evidence; required current-head CI and trust-boundary review are still needed. No fork workflow or new scan was started in this review.

[S0RYUASUKA]

The review follow-up is pushed. The three contracts remain separately described; this PR stays Draft under the maintainer's intake request.

• Fixed the non-stream/SSE continuation parser and the outside-diff Anthropic 413 continuation resend. Direct handleResponses regressions reproduce the previous failures; 413 previously sent three requests instead of two.
• Detached renewal stops when a root, identity or pool token ceiling is configured, including a ceiling added after confirmation. It does not bypass the limit or pretend to reserve the original workflow budget.
• Successful image summaries no longer get a failure code. Fixed missing body-byte arguments in tests, switched the image-recovery crypto calls to Bun/Web APIs, and documented Windows-only renewal support.
• 211 lifecycle/image tests + 85 adjacent tests pass, alongside typecheck, privacy, file-size, structure and diff checks. Documentation build passes with 577 pages and 81,463 checked links. The previously disclosed broad-run timeout remains unresolved; a full-suite pass is not claimed.

Two safety/compatibility points are left for maintainer disposition: I retained rejection of EOF summaries without a normal stop reason rather than inventing end_turn, and retained explicit overflow refusal for ownerless callers rather than silently deleting historical images. Their inline replies explain the tradeoffs; finding-resolution and final readiness confirmations remain unchecked.

Please approve the current-head functional workflows and review runtime ownership/transport. No native Codex or local installed version was changed and no paid provider validation requests were sent.

[S0RYUASUKA]

The P1 continuation finding in your review is fixed, and I added the requested paired entry matrix:

Non-stream HTTP client	Renewal off	Renewal on
Empty-completion retry	completed, expected answer, 2 sends	completed, expected answer, 2 sends
Terminal-guard continuation	completed, expected answer, 2 sends	completed, expected answer, 2 sends

The test enters handleResponses, disables the search sidecar, and returns JSON or SSE according to the actual upstream request. The fix uses response content type in the shared continuation parser and retains the inactivity wrapper and cache observer. Before the fix the direct renewal-enabled empty retry failed; the image-bearing 413 continuation also made three sends rather than two.

Latest lifecycle/image run: 214 passed, 0 failed across 8 files. The preceding 85 adjacent continuation/empty-completion tests and typecheck/privacy/structure/documentation checks remain applicable because this last commit changes only the paired test fixture; file-size and diff checks were rerun. All connections are denied outside the fake upstream. No live paid validation was used.

CodeRabbit has acknowledged the parser/spend/logging/documentation fixes and withdrawn the EOF and ownerless-image fallback recommendations. Those withdrawals are not a substitute for your runtime-owner, compatibility or current-head functional CI review. The PR remains Draft awaiting your review and workflow approval; I have not dismissed your changes-requested review.

[Ingwannu]

Re-review at 7e09e8b: the continuation parser now uses Anthropic's actual response content type while retaining the inactivity wrapper and observer. The requested non-stream empty-retry and terminal-guard matrices with renewal off/on are included. I independently ran the four focused cache lifecycle/prefix/runtime-record files at this head: 149 passed, 0 failed (Linux/Bun 1.4.3, fresh homes, capped cgroup). This resolves the concrete failure in review 5563307655, which I am withdrawing.

The separate no-lossy-image and detached-renewal contracts still require the recorded broader runtime/ownership review and current-head functional CI. I have retained Draft and have not approved fork workflows, dispatched paid calls or started a new scan. The withdrawal closes my specific continuation blocker; it is not a whole-PR approval.

Concrete non-stream/SSE continuation blocker fixed at 7e09e8b; paired empty/terminal continuation controls are present and 149 focused tests independently pass. Separate whole-PR runtime/ownership review and current-head functional CI remain outstanding.

[Ingwannu]

Updated-head intake at ecb6af12cc1fb0ca76cf72d5419c8e0a0c3f53a2: the earlier continuation-specific change request was withdrawn only after the prior exact-head 149-test receipt, and is not being resurrected as a new finding on this rebase. It also was not whole-branch approval of cache renewal, rollout/process ownership, image-summary persistence or outside-turn accounting. Keep Draft pending the runtime-owner review already requested and functional CI on this new head; the previous head's receipt does not certify a changed tree. No detached renewal, paid warm request, runtime watcher or live conversation access was started here.

[S0RYUASUKA]

@lidge-jun @Ingwannu — author-side status at 444f639de0f102e3c3b6ad5a3e66aece773aafda:

I have condensed the description into the three separate acceptance contracts you requested, with explicit current-head commands and older receipts labelled by their actual commits. Integration conflicts are resolved; the PR is mergeable and two commits behind current dev. Current local evidence is 72 lifecycle-entry tests, 302 transport/recovery tests and 27 layout tests, plus typecheck, privacy, structure and file-size checks. The documented full-suite exception remains; no complete-suite, Linux or live-provider acceptance is claimed.

The outstanding maintainer actions are concrete:

1. Approve the current-head fork runs: Cross-platform CI, Catalog async contracts, React Doctor. All remain action_required; the Cross-platform run has zero executed jobs. My account has no repository write/maintain/admin permission.
2. Review the independently mapped prefix-preservation, running-turn ownership/credential/cost, and no-lossy-image recovery contracts. The description points to the relevant entry/regression suites and states the ownerless-overflow tradeoff.
3. Explicitly release the Draft hold when that review and functional evidence are sufficient. I have not used the automatic readiness checklist to override your intake.

There are no unresolved inline review threads or new concrete code findings currently awaiting an author fix. CodeRabbit's routing-document warning refers to wording already in dev; its docstring warning remains disclosed rather than misrepresented as passed. If the three-contract review needs a different scope split or further concrete evidence, please identify the required boundary and I will address it here.

This update changes review handoff only: no new code commit, workflow-policy change, live conversation access or paid model request.

[Ingwannu]

Follow-up intake at 444f639de0f102e3c3b6ad5a3e66aece773aafda against dev 1cf98c05d9db5a458dd78f835d38dc393f32f0fe. The cache/image branch is still Draft and its current hosted CI is successful. The current diff changes renewal/provenance, thread-writer ownership and image retry/compaction, so prior narrow dismissal of the SSE-versus-JSON blocker is not whole-branch approval. Preserve matched-prefix/writer fencing, explicit retention policy, ambiguous/committed-send refusal, image-only recovery and original request bodies. The remaining hold is independent review of that combined lifecycle/retention contract and owner acceptance; no new broad cache-default or live Anthropic claim is inferred from the author receipt. No obsolete auth-cors blocker is repeated for paths this diff does not change.

[S0RYUASUKA]

Thanks for the current-head follow-up. I will keep this Draft pending independent review of the combined lifecycle/retention contract and owner acceptance. The matched-prefix/writer fencing, explicit retention policy, ambiguous/committed-send refusal, image-only recovery and original-body guarantees remain review boundaries; the earlier continuation-specific dismissal is not whole-branch approval. No broad cache-default or live Anthropic acceptance claim is being added.

One CI distinction for the review record: at 444f639de0f102e3c3b6ad5a3e66aece773aafda, the hosted hygiene/label/target checks are successful, but the three fork functional workflows still report action_required:

• Cross-platform CI
• Catalog async contracts
• React Doctor

Those pending approvals are not functional test passes. Please approve these current-head runs so their actual execution results can accompany the independent lifecycle review. There are no new inline findings to fix at present; all eight existing threads are resolved and the branch remains mergeable. I will address concrete review or CI findings here without changing the installed runtime or sending paid provider validation requests.

[Ingwannu]

Execution approval is now submitted for the actual functional workflows at 444f639de0f102e3c3b6ad5a3e66aece773aafda: Cross-platform CI, Catalog contracts, and React Doctor. You were right to distinguish the earlier metadata-only success from executed functional CI. These execution approvals do not approve the cache-renewal behavior, spend/credential boundaries or integration; their actual results still need to complete.

[Ingwannu]

The approved hosted execution has now completed at 444f639de0f102e3c3b6ad5a3e66aece773aafda, and Cross-platform CI failed; the earlier green metadata was not functional test evidence. There are seven failing cases across the four shards: cold-spawn warm-up disposition (1), terminal continuation provider-owner rotation (3), Windows shim publication identity bindings (2), and the 30-image age-tiered history case (1). Logs: shard 1, shard 2, shard 3, shard 4.

Please reconcile/rebase against current dev and establish whether each failure is base-derived or introduced; do not weaken these assertions to clear CI. This is a CI hold, not a claim that your patch caused all seven failures. Catalog contracts, React Doctor and gates succeeded, but they do not override the failed test shards or the outstanding trust-boundary/owner review.

[S0RYUASUKA]

Reconciled with current dev a4f335c075f84b721f0122ae0534a4af81e86294 and pushed 3306ca4744947f5ff3dc90cad860b0bf0f8bdecb. The branch remains Draft pending the CI and combined lifecycle/retention owner review.

Previous hosted failure	Attribution and disposition
Cold-spawn disposition (1), Windows shim publication identities (2)	Base-derived: these source/test paths have no diff between the old integrated dev and 444f639. Carried dev's eb4bf967 disposition and descriptor/identity fixes without changing their assertions.
Terminal provider-owner rotation (3)	Introduced here: image preflight called buildRequest again for image-free requests. Authorization and stored-owner assertions were already satisfied; the extra build observations violated the exact-count contract. Skip image-free preflight; all three original tests now pass unchanged.
Native 30-image age tiers (1)	Introduced here: the shared fixed-image normalization reached native Messages, which does not own Responses compaction. Both native Messages callers now explicitly retain legacy tiers. The original 30-image assertion passes unchanged; Responses still keeps stable image bytes and bounded compaction.

Pinned Bun 1.4.3 / Windows receipts on both untouched current dev and the new candidate: the focused four-file failure selection passes 9 tests, skips 1 Linux-only symlink case, and fails 0. The candidate additionally passes the real lifecycle entry 72/72, image/prefix/layout group 116/116, typecheck, privacy scan, structure and size gates, and diff whitespace checks. Full commands and limits are in the PR Verification section. The Linux identity case still needs hosted execution; no assertion was weakened and no CI policy or size baseline was raised.

The changed-mode attempt returned no completed test summary after more than five minutes and was stopped. It is not a pass, and the earlier full-suite exception remains disclosed. No paid provider validation or installed-runtime changes were made. Please run current-head functional CI when approved; the prior head's Catalog/React successes do not prove this new head. No whole-branch approval is inferred from the earlier continuation-specific review.

[S0RYUASUKA]

I ran the unmodified workflow's release-gates lane in the public fork before asking for another approval cycle:

• Untouched dev a4f335c: successful run, 22 executed jobs successful. This is the requested lane, not the skipped full Windows/control lanes.
• PR head 3306ca4: failed run. The wider Linux/macOS run exposed 20 distinct failed test cases beyond the earlier seven-case selection.

The failures reduce to three fixes in candidate 8596ce3:

1. Explicitly retain legacy parent-only reasoning replay in ordinary Responses and native compact ingress. Identified children still take precedence; this does not supply an own-thread identity for Anthropic renewal or image recovery. Existing account/model-switch, foreign-candidate, native compact and key-rotation assertions stay intact.
2. Add the three extracted image modules to the existing source-oracle inventory, so its size and dependency checks actually cover them.
3. Give the positive routed-summary fixture its required stop_reason: end_turn. The runtime's refusal of incomplete or tool-bearing summaries is unchanged.

The corrected candidate passes 272 focused tests: 64 native gateway/conversation, 69 opaque replay, 64 key-failover, 3 module/auth checks, and 72 real lifecycle-entry tests. Typecheck, privacy, structure, size and diff checks pass. No existing assertion or limit was relaxed.

The new candidate is on a validation-only branch and its original CI rerun is in progress. I am keeping the PR branch at 3306ca4 until that run is green, to avoid repeatedly resetting upstream approval for unvalidated updates. The local-validation checklist is now unticked because the current PR head has known failures. A fork success will not replace the upstream required checks or the lifecycle/retention owner review. The PR stays Draft; no installed runtime or paid model validation was used.

[S0RYUASUKA]

The next fork run did not pass: 39712861272, exact candidate 8596ce3daf0a16d8552019569acf726d836b354a, has six distinct failing cases (platform duplicates counted once). Untouched dev a4f335c remains the successful original-workflow control.

Candidate be3a883960cfccff7beb935bb817786a7ad10b95 addresses these without changing the installed runtime:

• The parent-only hosted-search regression exposed a real compatibility leak: an unidentified child could publish an Anthropic stripped-history memo under its shared parent. Such requests can still recover their current explicit signature refusal, but cannot publish a cross-request memo. The existing actual-adapter regression now passes; a policy-level negative case was added.
• Two pre-existing 413 expectations required the removed degraded-image resend. They now assert a single terminal send and retain context error classification, original image presence and zero queued/in-flight pacing slots. The 401/429 recovery assertions remain intact.
• Three cohort/reparse expectations conflated parent routing identity with reasoning ownership. They now require the explicit child id, reject the parent as replay owner, and preserve the existing repeated-reparse, routing, cohort, content and one-recovery checks.

Offline verification on the new tree: 203 passed, 0 failed across all five affected files; 47 passed, 0 failed in adjacent signature recovery. Typecheck, privacy, structure, file-size and staged diff checks passed. No assertion was deleted, no size limit raised, and no CI workflow changed. These deliberate contract expectation changes are disclosed rather than described as unchanged assertions.

The original release-gates workflow is running once on the independent validation branch: 39717499283. The PR branch remains 3306ca4 until the candidate passes, to avoid resetting upstream approvals for each intermediate fix. The explicit Draft hold and outstanding lifecycle/retention owner review remain in force; fork validation is not upstream approval or a full Windows/control-lane receipt.

[S0RYUASUKA]

Narrowed the final tree back to the two originating goals: running-turn cache renewal and image-pressure compaction/continuation. Generic reasoning replay identity, parent fallback and signature-rejection memo rules now match integrated dev; all eight affected source/doc/test files are byte-identical to that baseline. The two tests added solely for the withdrawn identity migration were removed with it; upstream's original assertions are restored unchanged. My earlier description of parent-only memo behavior as a newly introduced vulnerability was inaccurate; that follow-up is withdrawn rather than being presented as part of this fix.

The explicitly requested shared image allowance remains 26 MiB, including native Messages; native image tiers and other processing remain unchanged. Responses preserves stable historical image bytes and compacts complete old units. Recoverable upstream image 413 now releases its refused response, summarizes once and continues the same turn on direct/search/media paths, sharing the original cancellation and physical-send budget. A repeated 413 or irreducible newest unit still refuses; checkpoint replay does not summarize the same prefix again.

Pinned Bun 1.4.3 offline validation: 648 passed, 0 failed (entry 88; original replay/signature/native behavior 299; cache/images/transport 170; refusal/budgets 91). Typecheck, privacy, structure, file-size and whitespace checks passed. No full-suite local success, live natural acceptance, changed CI policy or paid model validation is claimed.

Pushed current head 259c87df7959d598a2d15aae1bd4843f1f5500ce after original release-gates run 39721934382 completed successfully on that exact head: 22 executed jobs successful, no failures. Untouched integrated dev already passed the same workflow. Superseded candidate receipts are not current-head evidence. The PR stays Draft under the explicit maintainer hold, pending current upstream CI and combined lifecycle/retention owner review; no merge or installed-runtime change was made.

[S0RYUASUKA]

Reconciled this branch with dev 880127dbd356c720779222a14a97c11adc8cf881. The latest conflict was only the test layout's explicit shard roster; both upstream's chat shard and this PR's cache-lifecycle shard are retained. The preceding integration likewise retained both independent fixture registrations. Runtime changes merged without a manual business-code patch or new behavior.

The diff against new dev still contains exactly the same 62 paths. The eight withdrawn replay/rejection source/doc/test files remain byte-identical to new dev, and the explicitly requested 26 MiB allowance remains. No identity-migration, parent-fallback or rejection-memo branch was reintroduced.

Current merge db134eedde9b7be1e0eb9101d35d0950a44a1d0a passes 115 offline tests: lifecycle entry 88 and test-layout guards 27, with zero failures. Typecheck, privacy, structure, file-size and whitespace checks pass. The prior 303/648-test receipts remain historical; a local full suite, live natural acceptance and real-provider savings are not claimed.

Exact-head hosted validation passed: original release-gates run 39869279388, 18 successful executed jobs including all three macOS test shards; eight lane exclusions/skips are not counted as passes. Previous candidate results remain historical. Observed dev f210595 is nine commits ahead of the integrated baseline. I am publishing this validated head instead of repeatedly merging a moving tip before each publication. Any remaining integration conflict is recorded separately; this does not claim the branch is ready to merge. The PR remains Draft under the explicit maintainer hold; fork success does not replace current upstream required CI or combined lifecycle/retention owner acceptance. No installed runtime was changed or restarted, no paid model validation was sent, and no CI policy was changed by this PR.
