# Image cache evidence for [#15676](https://git.cafe/pingdotgg/t3code/issues/15676)

Core paired endpoints reproduce stale blue R5 on base and fresh yellow R5 on the fix in all four web cells. The final proof audit supports W1 in all four actual MP4 cells, including later frames of head wide-light and stale base narrow-light near 291s. **W3 streaming stability is unverified. The full matrix is insufficient; central regression proof is supported, with remaining rows explicitly cannot-verify.**

## Provenance and rendering environment

- Captured base: [b5a226e49c](https://git.cafe/pingdotgg/t3code/commit/b5a226e49c52ecab4ddc2d678a7012d97e651a6a); captured feature head: [89ee147526](https://git.cafe/pingdotgg/t3code/commit/89ee147526dc132b44b573c112e18efb3b28e38f). Captures were made 2026-10-22 approximately 00:19–00:43 UTC. Reflog places feature head at 2026-10-21 23:50:04 UTC and the later main merge [3098ef2f93](https://git.cafe/pingdotgg/t3code/commit/3098ef2f934aee68acab769852de52566eadf132) at 00:47:49 UTC. Old dev logs identify head checkout `/home/ubuntu/wt/issue-15676` on web5817/backend13857 and base checkout `/home/ubuntu/wt/issue-15676-base` on web7881/backend15921; base reflog starts at b5a226e49c at 23:57:15 UTC. Existing metadata has no embedded SHA: attribution is reconstructed from checkout/reflog, launch logs and capture timeline, not cryptographically stamped at capture.
- Fixtures committed later as [e76c41919d](https://git.cafe/pingdotgg/t3code/commit/e76c41919d5dc466d8c2091211e9746689bb2d7d). All eight implementation paths are unchanged between captured feature head and the merge. Fixture commit changes only seed script/data. No evidence artifact is committed.
- Real web development app, T3 collaborative browser, Linux x86_64, Chrome/154.0.0.0, DPR 2. Reported CSS viewports: wide 1440×900 and narrow 390×844, each light/dark. Wide recordings are 2880×1800, but saved wide stills are 1280×800; narrow recordings/stills are 780×1688. Wide-still scaling/viewport discrepancy is unresolved and must not be described as exact 1440×900 still proof.
- Font: `16px / 24px -apple-system, BlinkMacSystemFont, "Segoe UI", system-ui, sans-serif` (computed stack; installed face not recorded). Themes: light `oklch(0.992 0 0)`, dark `oklch(0.145 0 none)`. UI clock frozen at 2026-10-22 00:00 UTC for matching relative labels; timing marks use performance time, not frozen UI Date.
- Synthetic project and image files in isolated worktree state. R1–R4 are static projection fixtures cloned from app-written rows, not event-history proof. R5 comes from a real Claude Sonnet 5.5 turn through app commands. Same path overwritten in place; ordinary cache retained during each decisive sequence; no reload between overwrite and R5. Separate base/head sessions.

## Paired endpoint index

`diff0` is whole-surface absolute RGB difference amplified ×8 (black means equal); `diffT` is a magenta mask where maximum absolute RGB channel delta is >16/255. No crop/mask excludes surrounding UI. Counts below are pixels, not percentages. Endpoint differences can include layout/scroll/caret differences and do not themselves prove timing.

**Narrow light uses `base-narrow-light-settled.png`.** The earlier `base-narrow-light-final.png` shows Thinking with no R5 and is not the decisive before endpoint. Existing final-pair statistics already name the settled file; the packaging pass independently checked the matching diffs against it.

Before — narrow light, stale blue R5:

## Static boards and whole-surface comparisons

Board 0 shows upper PNG/inline/file-URL/tall fixtures; boards 1–4 overlap the lower SVG/fragment/missing/blocked/linked/direct-data section. Repeated lower boards are not additional independent cases. Narrow boards match exactly; wide boards differ by 0 or 17 pixels consistent with composer caret. This establishes visual parity of captured fixtures, not correctness of every URL/fragment branch. Authored-size and spaced/encoded supplemental fixture data exists but has no captured board.

Other initial/expanded pairs and all metadata are linked in the artifact catalog below. Expanded overwrite images differ intentionally (base blue/head yellow); static gallery boards use yellow source bytes on both builds.

## Recordings: steps and times

Times below are recovered marks in seconds from recording start; encoded duration is measured from the actual MP4. Marks are approximate and can diverge from encoded time after transport stalls/static-frame handling. Raw recordings are untrimmed. The overwrite happens through the fixture command outside the browser, so a colored transition alone does not document disk bytes; the script, metadata, reply labels and endpoint samples support that sequence.

Review sheets were regenerated during packaging directly from the current final `*-recording.mp4` files (sampled 0%, 35%, 70%, 95%; not edited recordings). Old `*-contact.png` files are excluded from publication because one was stale. Sheets are sampling aids, not a claim that every intervening frame was inspected.

## Honest matrix result

| Row | Result | Evidence and remaining gap |
|---|---|---|
| W1 | Supported in all four web cells | Final proof audit inspected actual MP4s and confirmed stale base R5 / fresh head R5 in all four cells, including later head wide-light frames. Base narrow-light decisive at approximately 291s; use settled endpoint. Short contact-sheet sampling initially missed the wide-light result. Attempted repeat failed transport but is not needed for existing recording proof. |
| W2 | Partial | PNG, tall/inline/file URL/relative source and SVG boards in four cells. SVG fragment source renders, but clipping semantics not independently established. No authored-size/spaced/encoded supplement capture. Wide still dimension discrepancy remains. |
| W3 | Unverified | Eight attempted streamed-reply recordings exist. All metadata only reports a final streaming:false event; head image observations are empty. No independent chunk-by-chunk stability/flicker proof. |
| W4 | Unverified | No file-preview workspace mutation or reconnect recovery recording. |
| W5 | Partial | Four-cell base/head PNG/SVG open, next, close recordings. Separate static gallery board does not establish all post-R5 reauthorization/reopen paths. Linked href retained diagnostically, not clicked. Full linked-image click semantics remain unproven. |
| W6 | Partial static only | Missing/blocked placeholders on boards. No permission-restricted session, deterministic loading, disconnection or recovery proof. |
| W7 | Unverified | User/plan/reasoning/tool/file-preview/PR/attachment undefined-revision control board not captured. |
| W8 | Partial | Blocked/missing and direct-data fallback visible. Direct data is unavailable on both sides, not a successful direct-image control; GitHub/context-reference paths not verified. |
| N1–N4 | Unverified | Both iOS EAS builds failed GhosttyKit; no iOS screenshots or interaction proof, no retry. Android unavailable. Browser at 390 is not native evidence. |
| E1 | Partial diagnostic | Head createUrl observations have only resource input and hasRevision:false (1/2/3/4 calls for wide-light/wide-dark/narrow-light/narrow-dark). No remote host-local fallback, environment-separated-cache or relay/tunnel proof. Empty base RPC observations are not positive exclusion proof. |
| X1 | Excluded | Video media playback intentionally outside scope; evidence MP4s document image behavior. |
| Desktop | Unverified | No Electron client verification available. Shared web source is not desktop proof. |

## Supplement after merge and fixture commit

The primary agent independently reported a real-app no-reload check at [e76c41919d](https://git.cafe/pingdotgg/t3code/commit/e76c41919d5dc466d8c2091211e9746689bb2d7d) on a 1280×800 browser: four loaded yellow images stayed yellow after same-path overwrite to RGB(208,0,208); a new Claude reply rendered magenta. The prompt itself also embeds magenta, so six elements represent four old replies, a user prompt and a new assistant reply. This is a supplemental still/pixel transcript, not paired-base evidence or a recording and separate from the paired recordings.

## Packaging, fixtures, friction and server handoff

- Public uploads contain only synthetic screenshots, image-behavior recordings, diff images and sanitized metadata. No database, stopped-thread snapshot, server/build log, pairing link/token, signed asset URL, secret/config file or private EAS build-status document was uploaded. Text metadata scanned for token/auth/secret/userdata markers; still/contact-sheet visual review showed only the synthetic project. Packaging visual review was sampled, not exhaustive OCR of every video frame. Final proof audit separately confirmed W1 in all actual MP4 cells and reported verification of 180 upload hashes/diffs; the publication manifest contains 208 evidence uploads with locally computed SHA-256 hashes.
- Seed files reviewed and committed only: `scripts/fixtures/image-cache-proof.py` and `.json`. Uses Pillow and a Linux LiberationSans font path; creates labelled PNG/SVG, backs up an isolated `.t3` DB, clones V2 projections, and leaves event history unchanged. Requires a stopped sandbox server and an existing app-created thread/template reply. This Linux-specific fixture helper is not a cross-platform installer. Packaging checked Python syntax, JSON, embedded synthetic PNG, and images-only yellow PNG/SVG generation; no database opened or mutated during packaging. Formatting hook passed; no implementation change, push, PR, watch or merge performed by packaging.
- Friction: short contact-sheet sampling missed later wide-light proof; final audit of actual MP4s confirmed it. Wide-light retry hit MCP HTTP transport error. Base narrow-light turn stalled for minutes, and its earlier final still was Thinking. Wide screenshots and CSS metadata disagree. Stream diagnostics never observed streaming. EAS failed GhosttyKit. Migration 68–70 divergence is a warning, not proof of a failed server; primary confirms healthy app. Fixture script/data were explicitly required despite a reviewer preference to omit them.
- Prior capture launch ownership is established for worktrees/ports by the recovered activity and dev logs, but no surviving numeric PID can be proven to belong to that old step. Base web7881/backend15921 had no listener at handoff. Current head web5817 PID 1809303 (cwd apps/web) and backend13857 PID 1809328 (cwd apps/server) belong to the primary’s later launch, not the interrupted capture step; primary will stop them. Packaging started/killed no server and made no DB change. These are point-in-time observations; recheck before acting.
