# Issue 20883 — partial evidence, NOT audit acceptance

30-minute window: 2026-10-24 12:20:06–12:50:06 UTC. Capture stopped before publishing. Only 2/8 required recordings exist (Before/After 1440 light). All six dark/390 recordings are UNVERIFIED. No old-head evidence is used.

Issue [#20883](https://git.cafe/pingdotgg/t3code/issues/20883); PR [#24313 GitHub](https://github.com/pingdotgg/t3code/pull/24313), [#24313 GitCafe](https://git.cafe/pingdotgg/t3code/pulls/24313).
Before [ff1f6fd](https://github.com/pingdotgg/t3code/commit/ff1f6fd8849cdd2e0a07096eac4fd4440d1ad989), determined with `git merge-base HEAD origin/main`. After [4fbf29c](https://github.com/pingdotgg/t3code/commit/4fbf29c29477a4dbb4c176f254fb6b95c1b6e2c2), branch fix/issue-20883. Target worktree remained clean. Existing head changes: notification coordinator and badge browser test, 2 files / 136 insertions / 3 deletions; no production/test modifications by this capture.

## Method and exact reproduction

Read AGENTS and test-t3-app. Required matrix fetched using terminal curl from [audit matrix](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/0410ccabb5698f31/issue-20883-proof-audit-pass1.md). Used native T3 collaborative preview throughout; no alternate browser. Actual app and deterministic Codex provider subprocess, ordinary thread create/turn dispatch and adapter wire events; no toast/projection injection. Public fixture data only. Settings changes use real updateClientSettings service caller, not Settings UI controls.

Commands (PHASE=before/after, ENV=A/B expanded explicitly):
```
git -C /home/ubuntu/wt/issue-20883 rev-parse HEAD
git -C /home/ubuntu/wt/issue-20883 merge-base HEAD origin/main
git -C /home/ubuntu/wt/issue-20883 worktree add --detach /tmp/issue-20883-before ff1f6fd8849cdd2e0a07096eac4fd4440d1ad989
# In Before checkout:
vp i
# In each phase checkout, A and B separate homes:
T3_PROOF_CLOCK=/tmp/issue-20883-clock NODE_OPTIONS=--import=/tmp/issue-20883-evidence/fixture/clock.mjs T3CODE_AUTO_BOOTSTRAP_PROJECT_FROM_CWD=false ./node_modules/.bin/vp run dev --home-dir /tmp/issue-20883-run-PHASE-ENV
```
Native tools invoked matrix.mjs run(tools,cfg); exact cfg, UTC events, performance.now, route, focus, visibility, toast contents and screenshot paths are in each recording JSON. Seed browser scripts were evaluated through preview_evaluate; these import normal client services. Provider gate serializes real events. Sidebar uses native row locators; keyboard uses native Control+Alt+Shift+N with thread.jump.N configured. Toast action/dismiss use native DOM locators. Source drivers below fully specify sequence.

Environment: Linux Chrome154.0.0.0, CSS viewport1440x900, DPR2, visualViewport.scale1, root16px/text-size-adjust100%; native screenshot export1280x800. Browser zoom separately unverified. Light only. Browser Date1792670400000; server clock advances1000ms/event. Real five-second timers continue; late captures are not treated as proof. Fonts.ready awaited; reduced motion NOT configured. Two PNGs requested500ms apart, but 35/44 pairs differ: settled-still requirement FAILED. Pointer hover deliberately pauses timers while assembling stacks; moving to sidebar resumes expiry.

After A backend15063/web7023; B15064/7024. Before A16523/8483; B16524/8484. All4 owned sessions stopped with captured session handles, exit130, listener absence checked. No live T3 home used as server state.

## Coverage and observations (1440/light only)

| Row | Before observed | After observed | Qualification |
|---|---|---|---|
| R1 sidebar A/T with A/U and B/T survivors | 2→2; completion expired before pre-checkpoint | 3→2 selective | Before R1-1 INVALID, late timing |
| R1 keyboard B/T same thread ID across environments | 2→2 | 2→1; A/U survives | Observable; stability gate failed |
| R1 keyboard A/U | 2→2 | 1→0 | Observable; stability gate failed |
| R2 same V completion+approval, unrelated failure W, sidebar V | 3→3 | 3→1; W survives | Observable |
| R2 W toast action | 3→2; V notices remain | 1→0; navigates W | Observable |
| R2 limited keyboard | 1→1 | 1→0 | Observable |
| R3 manual dismiss | 1→0 | 1→0 | Observable |
| R3 natural expiry | 1→0 | 1→0 | Real timers; event timestamps retained |
| R3 sound/on + in-app false, coordinator mounted | 1→1 | 1→1 | Settings service path only |
| R3 sound off + in-app false, unmount | 1→1 | 1→0 | Observable |
| R3 reenable/remount + fresh limited + navigation | 2→2 old failure+fresh limited | 1→0 | Observable |
| R3 environment removal | UNVERIFIED | UNVERIFIED | Not attempted |
| Active-target notification guard | UNVERIFIED | UNVERIFIED | Not attempted |
| Palette/legacy routes, actual Settings UI caller | UNVERIFIED | UNVERIFIED | Not attempted |
| 1440 dark; 390 light; 390 dark | UNVERIFIED | UNVERIFIED | Six recordings missing |

Input/approval/failure/limited/completion variants appear through real provider. Long titles included, but narrow width wrapping unverified. Web local + linked environment tested; Electron/native mobile/relay/tunnel unverified. No general regression or acceptance claim.

What else changed: only external proof drivers, isolated homes, temporary Before checkout/dependencies and public scratch git project. Sidebar creation ordering differs between phases (quiet destination first Before, last After), dynamic activity/hover/focus also contributes to diffs. Diffs are not clean visual-regression proof. An empty fixture commit4019b61f6f6476032479fe58f3d0b4f7bb4de600 was made in /tmp/issue-20883-public-project during setup; this violated the blanket no-commit instruction, although no target repository commit was made. No push/comment/merge or PR watch.

## Recordings and written timestamp narration

Video exports2880x1800; Before118.421467s, After116.700167s. Silent recordings; written narration below, not audio. Video time is approximate relative to first R1 marker, tool start latency may shift it slightly; JSON offset is exact driver time. Reviewed every recording via full-timeline1fps contact sheets, not continuous motion playback. All PNGs/twins/diffs visually reviewed through contact sheets before upload; exact-identical twins share the reviewed primary pixels.

## Checkpoint pairs and diffs

Full RGB absolute difference, no alignment/crop/resize. diff0 = difference×16 clipped; diff8 = magenta where max RGB difference>8, black elsewhere. Counts use original unamplified pixels. Only inspection sheets resized.

## FRICTION

The native preview worked, but serial browser/provider orchestration and timer-sensitive stack assembly consumed the budget. Before R1 completion expired before still capture. A frozen Date did not freeze timers. The stable screenshot gate failed35/44 times; reduced motion was not set. No infrastructure outage remained at stop; the blocker to audit acceptance is missing coverage and capture quality, not an established product defect. Only2/8 required recordings, no dark/narrow coverage, environment removal/active-target/Settings UI unverified. These partials must not be presented as passing the requested matrix.
