BEFORE [b5a226e49c](https://git.cafe/pingdotgg/t3code/commit/b5a226e49c), AFTER [25589e9002](https://git.cafe/pingdotgg/t3code/commit/25589e9002). Synthetic fixture/scripts commit [30dc719a59](https://git.cafe/pingdotgg/t3code/commit/30dc719a59b157970535930cbf8800d6e7b0b392), no production edits in the evidence commit; no push or forge comments.

## Coverage and limits

All four visual rows captured at 1440×900 and 390×900 CSS px, light and dark, before and after. A: 8 lifecycle recordings / 4 pending-frame pairs. B: 16 recordings split B1 (one/two/duplicate rerender) and B2 (supersession/mixed provider) / 24 checkpoint pairs. C: 8 recordings / 28 checkpoint pairs. D: 8 static stills / 4 pairs, explicitly a projection/composer-draft harness. Total **32 recordings, 120 before/after PNGs, 120 diff PNGs, 60 pairs**. No still substitutes for an interaction recording. G1/G2/G3: **30 passing schema-validated full projection/provider helper assertions**, not app or native proof.

Native iOS: **all matrix checkpoints unverified**. EAS availability returned true for pingdotgg. Ten recent iOS builds were checked: no finished matching base/head static build was established; recent base simulator builds were errored or in progress, and a finished simulator artifact was from a different commit. No stale binary was installed, no EAS session/build launched. Android and native Electron/Desktop: **unverified**, no target exercised. Narrow web is not native iOS evidence. Same-instance model requiring a new thread and incompatible same-driver continuation groups: **helper harness only**; those capability branches were not available in the installed app catalog. Disabled destination is integrated; other unavailable reasons are not separately exercised. Integrated source-account removal/custom-model selection is **unverified**; D proves rendering from a labeled injected state only.

## Environment and comparison method

T3-owned collaborative Browser panel, dedicated tab opened with reuseExistingTab=false; no standalone Playwright/global browser fallback. Linux x86_64, Chromium/Chrome 154 user agent, DPR **2**, browser zoom **1**, root font **16px**, default font scaling. CSS viewports exactly **1440×900** / **390×900**. Native snapshot output downsamples the 1440 viewport to **1280×800 PNG**; 390 viewport produces **780×1800 PNG**. Do not interpret saved PNG width as CSS viewport. Recordings retain their reported dimensions in video-stats.json. Computed body font stack: -apple-system, BlinkMacSystemFont, "Segoe UI", system-ui, sans-serif; no font override was injected. Before/after share the same browser, home snapshot, sidebar/details closed, composer empty at checkpoints, scroll at default/top with no active overflow scroll entries, and app theme (light/dark class checked). Date/Date.now frozen to **2026-10-22T00:00:00.000Z** in server and browser; event timing uses a separate monotonic clock. Real provider/network durations differ; these are behavior recordings, not synchronized latency benchmarks. Capture metadata and scripts report relative seconds for each action.

Base Vite on 7861 and head Vite on 7860 shared a dedicated no-watch evidence server on 15900 with isolated worktree .t3/proof. The lead's server15895/web7855 were untouched. No private copied conversation was captured: dedicated project, harmless generated PARENT_READY/FORK_* prompts, actual Codex and Claude turns. Settings credentials, SQLite files, auth/pairing tokens and EAS private responses are excluded from uploads. No manual writes to live T3 database. T3 browser tools themselves store their captures in the app-owned artifact directory.

Each pair has an uncropped absolute RGB diff at **threshold 0 amplified ×8** (any nonzero channel delta), and a binary white-on-black diff at **max channel delta >16/255**. Equal dimensions are required. Pixel counts and bounding boxes use saved-PNG coordinates, half-open bounds. Every component outside the expected divider zone is listed below, including single pixels; none were masked out of either diff. Small prompt-edge/composer-edge pixel differences are consistent with screenshot resampling/antialiasing (inference), not evidence of a functional layout change. Threshold16 is diagnostic, not a pass filter.

## Recording timing and scale repair

Recording repair: A/1440/light now has decoded-frame seek times below, separate from the original RPC/DOM action log. Action-log seconds elsewhere are execution times, **not video seek positions**. Native recordings are sparse variable-frame-rate streams; seeking with ffmpeg can return the next encoded frame rather than the frame being held at that instant. The corrected A times were checked against decoded frame presentation timestamps (PTS), not a constant delay assumption. For exact extraction use frame number minus1: `ffmpeg -i A-after-1440-light.mp4 -vf "select=eq(n\,10)" -frames:v 1 return.png` extracts published frame11 at PTS5.507933s. This avoids forward seeking into the next event.

C/1440/light BEFORE and AFTER were replaced together. The old clips shrink the whole application into the upper-left of the canvas around restore/disable, then expand; AFTER shrinks again around reenable (auditor samples: BEFORE 3.527/3.707s; AFTER 3.630/3.834/5.191s). The precise cause was **not established**. Scaled snapshot/compositor interaction was suspected from the capture implementation, but a separate diagnostic did not reproduce it, so it is not asserted as the cause. Those two old clips are excluded from the final proof; their originals remain archived locally.

Both replacements run the same original C sequence through the real composer store and settings RPC: original → GPT-6-Astra → secondary Codex account → incompatible Claude → restore → disable → reenable. Both use the same copied c-start SQLite snapshot in a fresh isolated `.t3/proof-repair` home, server15931, before Vite7882 / after Vite7881, the same native Browser tab, Chrome154/Linux, CSS1440×900, DPR2, zoom1, root16px/system font, light theme, frozen Date, closed sidebar/details, empty composer and default scroll. Provider readiness and equal Codex continuation groups were confirmed. All checkpoint metadata reports viewport1440×900, DPR2, zoom1, main1440×900 and no scrolled elements. No new turns were sent. Web/client-runtime production files at the current merged head are byte-identical to the original production fix. Browser-origin/environment identity differs from the old capture, without changing fixture content.

To avoid contaminating these recordings with scaled screenshot capture, no snapshots run during them; each state has a 1.6s action hold. The two delivery MP4s are CFR30 copies of the native recordings (existing frames repeated, plus a disclosed 2s cloned final-frame hold; H.264 re-encoding, no crop, spatial rescale, splice, or speed change). Every distinct decoded native frame was inspected: the page remains full-canvas throughout. Seek times below are from the final delivery MP4s. All other 30 recordings, all120 checkpoint PNGs, all120 diff PNGs, and diff-stats are preserved. The contact sheet changes only its two C/light/wide cells. Native gaps and all original behavioral limits remain in force.

## Real-app script and boundaries

A: complete a synthetic parent Codex GPT-6.1-Sol turn, fork and complete a synthetic fork turn, record → dispatch actual thread.merge_back → settled pending frame → focus source and destination → navigate through app router to fork and back → dispatch actual message.dispatch → observe pending removed and persisted Context handoff row. Clip ends at consumption/persisted-row milestone, sometimes while provider is still Thinking/Working; **assistant response completion is not claimed**. The old automated `reply:true` flag only matched text also present in the user prompt and is not accepted as response-completion proof. No pending duplicate remains at that milestone. The persisted row includes full source/destination models because that unchanged historical renderer has run metadata. Foreign-thread footer check is false in all A clips. Route changes can briefly show an unloaded timeline before fork items arrive; this is visible in recordings and not hidden.

B1: configure long Codex displayName plus enabled sibling codexEvidence to expose CR/CS badges; complete two forks; record → merge first → merge second → change draft model then restore to force a rerender → focus account endpoint. Both duplicate same-provider sources remain, separated by comma, through rerender. B2 starts from two pending Codex sources with both forks' second turns already complete (one Codex, one Claude); record → remerge first → remerge second → focus long endpoint. The existing source is superseded rather than a third source appearing; mixed list is Codex + Claude. **No multi-source send was attempted or proven**: server's existing multiple-fork consumption limitation remains. Identical React source keys remain a code risk; no disappearing/reordered endpoint was observed in these rerenders.

C: from A pending state, record → same Codex account switch to GPT-6-Astra → codexEvidence GPT-6.1-Sol (actual ready catalog, same codex driver, equal defined continuation group) → Claude Fable5.1 → restore original Codex → disable Codex through settings RPC → reenable. Compatible changes retain provider-only merge source on head and use live destination model/account. Incompatible driver keeps the existing full last-run source model on both revisions (precedence); disabled hides on both, restored enabled destination restores only the new merge preview on head. Model/account changes are driven through the real composer draft store and settings service, not picker-click-path coverage. Merge/send are app service RPC commands and navigation is the real app router; no DOM-only fake divider is inserted. Focus calls drive actual endpoint elements; focused tooltips appear in sampled A recording frames. No mouse-hover timing or native press alert claim.

D: with server stopped, alter only synthetic pending transfer source to missing removedEvidenceAccount, then inject custom-evidence-model through composer draft store. Clear evidence-origin IndexedDB thread/shell/server-config caches before loading to avoid a stale same-sequence projection. Source raw ID and RE fallback avatar, destination raw slug render on head. Composer picker visibly falls back to GPT-6-Astra while the preview reads the injected draft; this discrepancy is retained, so **this is not proof that the custom slug is ordinarily selectable**. Base lacks the pending row. Only static appearance captured.

Static replay: initialize a fresh disposable child home under worktree .t3 with the server, stop it, run `python3 scripts/fixtures/issue-15063/seed.py .t3/<new-home> single|duplicates|fallback`, then start against that home and clear only its browser-origin projection cache. Fixture JSON contains synthetic projection rows only, no event history/outbox/auth: **do not send turns from projection-only replay**. Badge/custom draft setup is printed by seed.py. The original recordings used real fork/merge/send events; replay seeds do not replace that proof. Seed insertion tested for all three variants with SQLite integrity checks; repeat against populated home refuses. `node scripts/fixtures/issue-15063/verify.mjs` runs 30 full-schema helper cases, including guard/filter/order/duplicate/precedence cases.

## Visible differences

A: head adds the pending label, provider-only Codex source, arrow, GPT-6.1-Sol destination and rules. At narrow width the divider wraps; composer and last message stay clear. Base has empty space there. After send both revisions use the same existing persisted handoff path. B: head adds one/two source endpoint arrays, account icons/badges, comma separator, arrow and destination; long account name truncates with ellipsis, narrow rows wrap across lines. Superseding does not add a third source. C compatible/original/restored/reenabled: head adds the merge preview; switching models changes destination label and normal composer model/effort on both revisions, switching account changes destination badge on both. Incompatible and disabled controls have no intended revision difference. D: head adds raw missing account/provider-only fallback and raw custom model slug; picker fallback remains visible on both. Theme, prompt, response, header and composer layout otherwise match except the explicitly enumerated pixel components below. Per-recording durations/status timing vary because provider work is real; no performance claim.

## FRICTION

- PASS2 repair: original wide/light C recordings also changed scale mid-flow; cause unestablished, so both were replaced together under matching conditions. No snapshots during replacement recordings; decoded PTS verified. All other captures/diffs preserved.
- PASS2 repair: wide A action-log times preceded visible frames; supplied decoded-PTS seek samples and explicitly limited source-focus proof. No single compositor-delay offset is assumed.
- Repair startup: original evidence servers were stopped before this task; used a fresh isolated home and own ports. A new environment ID required correcting the route; cold Vite startup required waiting for PARENT_READY. No live state or existing server was modified.
- Artifact GET validation initially returned403 with Python’s default user agent; a Mozilla user agent succeeded, and replaced PNG/stats/contact-sheet hashes matched local files.
- Native preview locator/complex-selector click calls were rejected as invalid, so actual app RPC, router, DOM focus and composer store drove the flows. Browser stayed native throughout.
- Provider catalog required a server restart after adding a compatible account; the restarted catalog confirmed ready models and equal continuation group before C.
- Frozen Date does not freeze all provider/performance timing. Recordings stop at the consumption milestone rather than completed assistant text; the initial generic reply-text boolean was not a valid completion assertion and is explicitly rejected above.
- Native screenshots resample wide DPR2 captures; tiny unmatched prompt/composer raster pixels are exhaustively retained in diffs below. No crop/mask was used.
- Direct projection D initially hit stale browser cache at the same sequence. Excluded captures were replaced after clearing only the evidence origin cache and confirming raw source ID on screen.
- EAS access exists but no matching finished native artifact was established; iOS, Android, Electron remain unverified. No public forge post, PR, push, production edit, or live-home seed write.

Verified clip-relative visible checkpoints (exact decoded frame PTS, frames counted from1; not action times): **3.988533s / decoded frame3** parent PARENT_READY and no pending divider (base control) → **6.726267s / frame11** fork timeline loaded, FORK_ONE_READY visible and no pending divider → **7.202600s / frame14** parent route restored → **7.817067s / frame16** next user prompt plus persisted Context handoff row; provider work remains in progress. Base has no pending endpoints to focus. Original merge/focus/router/send action order is retained in the action log; those execution times must not be used as video seek times.

Action log / execution seconds (not video seek times): 0.000s recording started → 0.420s merge_back RPC from completed synthetic fork → 1.617s settled pending checkpoint → 1.892s focus source endpoint (absent on base) → 2.711s focus destination endpoint → 4.234s navigate to fork through app router → 4.910s foreign-thread pending check → 5.300s navigate back through app router → 5.688s send next prompt via app RPC → 12.740s settled consumed state.

Composer catalog fallback remains GPT-6-Astra on both. Other visible raster deltas outside divider: 92 pixels at [967, 674, 968, 766]; 2 pixels at [967, 671, 968, 673]. These correspond to prompt glyph edges / 1px composer right border or composer glyph pixels; resampling/antialiasing is an inference. |
