No blocking proof findings remain for [#32924](https://git.cafe/pingdotgg/t3code/pull/32924). A4 and S1 fill the two gaps from the previous audit. The new evidence contradicts none of R1–R4, whose accepted results carry forward.

The [capture report](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/2315f3c22e3412ff/capture-report.md) labels before [fa2f4ff2a2](https://git.cafe/pingdotgg/t3code/commit/fa2f4ff2a2bac5ac92e07749f6b83b0003d642a0) and after [41a714dda9](https://git.cafe/pingdotgg/t3code/commit/41a714dda95a07c82dd05eda4b53c001e3d2d578), consistent with the PR's observed base and head. The reviewed checkout and independent rebuild both resolve to that exact head. Historical before/after checkouts have already been removed; their labels are reported provenance, not cryptographic attestation. The independent after rebuild provides direct source-to-image verification for A4 wide.

| Row | Status | Evidence assessment |
|---|---|---|
| R1 | SUFFICIENT | Earlier audit: sole current failure closes through inline and popover Retry; no new contradiction. |
| R2 | SUFFICIENT | Earlier audit: current becomes done beside a behind server retaining Retry; no new contradiction. |
| R3 | SUFFICIENT | Earlier audit: retained provider diagnostic, Retry becomes Dismiss, dismissal restores footer; no new contradiction. |
| R4 | SUFFICIENT | Earlier audit: done and provider-only failure coexist, then Dismiss; no new contradiction. |
| A4 | SUFFICIENT | Matched 1440×900 dark and 390×844 light captures and recordings. After Retry, current server target is null and provider failure remains; behind target remains retryable. Both diagnostics, “2 failed,” Retry and Dismiss coexist. |
| S1 | SUFFICIENT | Real Electron, labelled updater-state harness, 1920×1080 dark. Review and Update track are disabled initially on both sides; after Retry and reopening About they remain disabled before and enable after, with run null only after. |

Opened all 12 delivered initial/final stills, all 12 diff images, all six comparison sheets, and all six delivered video contact sheets. Downloaded and probed every recording; independently extracted 73 frames at every recorded event, the report's approximate narrated times, 0.4 seconds after events, and near each recording's end. Opened all 73 uncropped frames in 21 full-frame sheets. The written narration agrees with the recorded sequence, allowing the next paint after interaction marks. A4 reaches its settled diagnostic by 2.4s and holds it through the endpoint near 6.3s. S1 closes About around 2.4s, retries around 3.57s, reopens around 5.6s (visible by 6.0s), and holds the claimed controls near 7.83s through the end. Web recordings are 25fps; Electron recordings are 20fps at the stated dimensions.

No ghosted elements, stale overlays, persistently loading endpoints, clipped diagnostic text, unintended blank regions, wrong viewport/theme, or unexplained changed region was found. The brief loading state during Retry and deliberate single-line ellipsis are ordinary transient UI, not capture corruption. S1's blur is the real Settings backdrop; closing About exposes the run and Retry in the recordings.

Recomputed all 12 diff images pixel for pixel. Diff0 is absolute RGB channel delta ×32, saturated, with zero threshold. DiffT marks maximum-channel delta >16/255 as magenta over the before image at 22% brightness. Every recreated diff matches exactly. All three initial pairs have zero changed pixels.

| Final pair | Any changed pixels | Max-channel delta >16 | Changed bounding box, exclusive right/bottom |
|---|---:|---:|---|
| A4 wide | 18,066 | 5,512 | (82,612)–(386,748) |
| A4 narrow | 24,012 | 4,711 | (71,556)–(390,691) |
| S1 harness | 11,596 | 1,084 | (105,261)–(1488,1080) |

The “what else changed” list matches the images and source. A4 changes only the current diagnostic and the popover's resulting 32px height/top/shadow change; the behind diagnostic, count, buttons and surrounding UI match. S1 changes only Review/Update track styling and the disappeared capsule beneath the backdrop. The wide S1 bounding box reflects these separate regions, not an unexplained rectangle of changes.

S1's limitation is honest and acceptable under this brief. The real native updater reports disabled because no feed is configured. The supplied driver seeds only the desktop updater display atom (enabled, up-to-date, nightly, version 0.1.8) and the failed-run fixture; it does not replace the bridge, backend, Retry coordinator, or disabled properties of the controls. The native refusal and before retained-run endpoint are recorded. This proves the About observer's disabled-state transition; configured-feed updates and actual track switching remain unverified and are explicitly not claimed. Harness labelling is present in filenames, comparison sheets, scripts, raw results and the report.

Rebuilt A4 wide in the required second detached worktree at the final head with `vp install`, `T3CODE_DEV_SEED=0`, and two fresh isolated server homes. Used the uploaded seed unchanged and adapted the uploaded web driver only for local checkout/home/port locations and one after-side wide case; its stability helper, interaction, fixture, browser settings and recording code were preserved. Chromium 148.0.7778.96, 1440×900 dark, DPR 1, 16px root font, reduced motion and frozen clock match the supplied evidence. Both initial and settled after captures match the delivered images with **zero changed pixels and maximum channel delta 0**. The runtime state independently confirms server=null with retained provider diagnostic on current, and server target 0.1.9 with real background-service refusal on behind.

The original Windows/macOS service and stale-config sequence, real provider failure production, and a native configured-feed updater remain outside the evidence. These limits were already disclosed; this pass accepts the client render/state claims only.

AI-assisted; verified with the tests and tools listed above.

FRICTION:
- tool | System Python lacked Pillow and NumPy; installed both in a scratch venv | Include image-analysis dependencies in the proof-audit runbook.

VERDICT: SUFFICIENT
