# Canonical proof closeout

Reviewed [#23807](https://git.cafe/pingdotgg/t3code/pulls/23807), canonical [080b9ab60e](https://git.cafe/pingdotgg/t3code/commit/080b9ab60ef6e0e156e0dc1aa135fa26480055e8) against [22840ab943](https://git.cafe/pingdotgg/t3code/commit/22840ab943b8418744b48223411e46ba4fdcef1a). Read-only source and existing public artifacts; no app, browser, server, install, test run, or new capture. No abandoned queue branch or its matrix reviewed.

Findings: no blocking proof discrepancy for the actual existing-notice fix. The full base-to-head diff changes only ClaudeAdapterV2, its tests, and the explicitly authorized reproduction recipe. No autoqueue feature is added. Stop emits a completed existing system_notice for each unconfirmed steer, quotes its text, and asks for resend. Assistant/stream/result prompt UUID echoes clear tracked steers only for the live query. Failed offers remove tracking; terminal handling clears it. Older CLIs can omit acknowledgments: the wording correctly states uncertainty rather than certain loss.

Capture drift: web evidence is from [20749b942a](https://git.cafe/pingdotgg/t3code/commit/20749b942a), not the reviewed final head. I compared the complete adapter diff between those revisions. The entire unread-steer snapshot/clear/notice emission block is byte-identical. Later changes add a stream acknowledgment test (production stream acknowledgment handling already existed at capture), change error payload to cause, and close admission at finalization entry before its first yield. The latter moves registration before the next yield and rejects late steers through the existing ended-turn error path. They do not change notice text, title, shape, or renderer. The intervening main merge changes unrelated sidebar/navigation/server/dependency code; therefore captures are not certified as exact final-head whole-screen snapshots. Web chat renderer, mobile, contracts, and shared client runtime have no capture-to-head diff.

Admission guard: source reasoning supports the claimed check/register ordering. No deterministic race proof is supplied, and the body honestly says so. A narrow registered-but-rejected-offer overlap can still yield a conservative warning alongside failed-send handling; no confirmed silent-loss regression was found. No requirement for a race test is invented by this proof audit.

Evidence: downloaded the URL manifest and its body-linked PNG/video/control artifacts. Four before/after cells visibly show the added amber notice/disclosure and shifted interrupted divider. Expanded narrow detail matches the current source string and quoted codeword. Incidental titles, sidebar ordering/ages, and artwork differences are disclosed; downscale and differing video latency are disclosed.

| Desktop | SHARED RENDERER, shell unverified | No shell changes; no independent Electron capture claimed |
| Native iOS notice/detail/expansion | UNVERIFIED, explicitly disclosed | Native source unchanged; web390 is not native proof |
| Final-head runtime capture | NOT RECAPTURED | Source equivalence supports notice only; not whole-screen equivalence |
| 211 adapter tests / 35 CI green | REPORTED | Not rerun or queried in this read-only audit |

All eight diff images were rebuilt from downloaded before/after PNGs: amplified absolute RGB delta x4 and black/magenta maximum-channel-delta>16 outputs are pixel-identical to their published counterparts. Counts match the manifest exactly. Also rebuilt the existing after390-light capture by lossless PNG artifact processing: identical dimensions and every RGB pixel unchanged. This is an artifact rebuild, not a new final-head runtime capture; no app-surface rebuild was performed within the expired capture budget.

Both full videos decode across their complete durations. Existing encoding emits non-monotonic DTS warnings during null-mux processing; decoded sampled timeline and final after tail are usable. Tail shows expanded detail, quoted codeword, and interrupted state. This pass does not claim a second frame-by-frame full-video inspection or precise timing proof. The sanitized consumed-steer control shows UUID echo/explicit recall before the second foreground task and subsequent Stop. Its no-warning conclusion is supplied by the control author; protocol excerpts alone do not prove UI absence. No-Stop recall remains reported evidence.

Body cleanup already assigned to lead: link the Scope first line and remove the redundant review log. Its scratch-file policy objection is superseded by explicit authorization of the committed recipe. Keep the historical native-only INSUFFICIENT V2 verdict clearly historical; it is not a claim of native verification. No new native matrix is required to support an unchanged native renderer, but native behavior must remain labeled unverified.

FRICTION: urllib download returned403; curl with a browser User-Agent retrieved public artifacts. Wide PNGs are downscaled and independent runs contain incidental pixels, so counts measure whole-image differences rather than notice-only changes. Final-head captures were not regenerated; source comparison establishes only unchanged notice behavior/rendering. Native access/build/transport limitations remain explicit. No private material uploaded; this report contains only source conclusions, public evidence facts, and disclosed limitations.

Proof closeout is sufficient for the scoped existing-notice server fix with the stated limitations. It does not certify native execution, Electron shell behavior, exact final-head pixels, deterministic race coverage, or newly rerun checks.

VERDICT: SUFFICIENT
