## Evidence
Artifact index (all row sheets, recordings, drivers and ghdrop output): [index.md](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/70d907d6decd1cea/index.md).
**Incomplete: 14 of 41 affected matrix rows have accepted before/after web captures.** Some of those rows are partial; the exact missing requirements are below every row. E12–E14 have diagnostic observations only. E17 native stills were rejected. All 23 optional affected rows remain unverified. This section is evidence, not a claim of complete verification or merge readiness.
**Outside-title observations requiring maintainer attention:** the native empty-state text remained clipped beneath its header; embedded Browser navigation reported `ERR_CERT_AUTHORITY_INVALID`; the baseline PR request failed to reach GitHub. These are not attributed to this PR. The reachable-link diagnostic opened **Changes**, not the selected commit, so successful E12 routing is not proven.
Before: [e34067edef][before]; after: [dbb22e5272][after]. Rendering head is the requested pinned head; the two commits above the contributor head change tests only.
Environment for every accepted pair: real web app from each separate checkout and fresh server-created database; Google Chrome for Testing 148.0.7778.96 through Playwright, Linux headless, no device emulation, DPR 1, browser zoom 100%, interface font 16px/code 13px, no OS font scaling. Viewport is stated per pair: 1440×900 unless marked 390×844. Light/dark are real app themes. Browser Date is frozen at 2026-10-29T02:00:00Z; reduced motion is emulated. Server-generated chat timestamps were not normalized: they are hidden in accepted stills, but time-sensitive chat portions of recordings remain unverified. Stills wait for network idle/fonts, then require byte-identical screenshots 500ms apart. Loading UI is intentional only in E03/E08 timing cases. Full surfaces are uncropped. Every viewport/theme combination not explicitly shown is unverified, including dark 390px and most light/narrow rows.
Synthetic Git content is shared by both servers. No live database was read or seeded. Description text is a labelled deterministic WebSocket response stub; Git lists/previews and normal app rendering use real RPC. E03/E04/E08 use response gates around the real app. Baseline lacks Commits, so baseline interaction stops at the existing source menu or selects Changes instead of an unavailable commit row.
Diff0: absolute maximum RGB-channel difference per pixel, amplified 32× (zero threshold). DiffT: orange where any RGB channel differs by more than 16/255, otherwise black. No statement of “nothing else changed” is made. Sheets are thumbnails only; table images link to uncropped originals.
### E01
**Coverage / unverified:** Recent dates absent (fixture dates are 24–26 days old); no generated real-provider text, deterministic transport descriptions explicitly stubbed. Long-subject tooltip not conclusively established.
**What else changed:** Commits submenu appears; subject and generated secondary lines, right SHA/date column and scrollable popup cover part of the unchanged branch patch. Description text is deterministic transport-stub data.

### E02
**Coverage / unverified:** Compact local geometry and plain SHA captured, but description stub answered generation; G-disabled/no-description requirement remains unverified.
**What else changed:** New local commit row has a secondary description from the fixture stub (this violates the requested G-disabled case). Selected header replaces Changes/base selector with subject/plain SHA; branch/dirty-file aggregate is replaced by the selected file and its totals. The selected file is collapsed.

### E03
**Coverage / unverified:** Real branch list responses gated in the actual app. First description request logged. No claimed real-provider generation.
**What else changed:** Commits submenu adds disabled loading text; releasing the real list replaces it with actual subject/SHA/date rows. The rest of the surface remains the branch comparison.

Steps/timestamps: see the E03 shared timing-reel chapter lists above. The same recording contains this row’s scripted release.
**What else changed:** Released description strings add a secondary line under subjects and increase row height; visible row count and scroll position change accordingly. Refreshed-list freezing was not exercised.

### E07
**Coverage / unverified:** 1440 dark/light selected header and source focus recorded. SHA activation/destination not exercised. 360px attempt rejected for incidental workspace overlay; its width requirement unverified.
Steps/timestamps: see the E01 shared menu/selection reel chapter lists above (dark and light).
**What else changed:** Changes/base-ref header becomes selected subject plus linked short SHA; counts and toolbar spacing change. The body changes from aggregate branch/dirty-file diff to the selected commit patch (red/green lines, paths and totals differ by design). These large body differences are the source selection being demonstrated.

### E10
**Coverage / unverified:** Real two-parent >120KB seven-file fixture and menu captured. Selected merge posters rejected: skeleton / wrong file surface. Lazy reads, context expansion and immutable parent/head contents remain unverified.
**What else changed:** Only the source-menu comparison is accepted: new commit rows include later workspace revision, merge and first-parent-related entries. Selected/lazy-file frames were rejected and no immutable-content claim is made.

### E11
**Coverage / unverified:** 390×844 light real sheet menu/header recorded. SHA activation, maximize/unmaximize and dark 390 variant unverified. Header subject collapses to a tiny selector at this width; SHA and controls remain visible.
**What else changed:** Real narrow sheet gains a Commits submenu and long rows; selected header loses branch base selector and shows short SHA with a very narrow subject selector. Selected commit patch and totals replace branch aggregate. 390px capture is light only.

**Coverage / unverified:** Web missing PR-commit fallback reaches the actual readable PR panel after waiting for its title. Desktop delivery stills rejected for ongoing Syncing messages. PR live metadata can change independently and does not constitute frozen fixture data. Baseline PR load ended in Could not reach GitHub while after loaded public PR data.

**Coverage / unverified:** Actual installed iOS client reached both states through identical controlled hook input: before shows Commit abcdef1 patch, after accessibility tree reports No review diffs.

To rebuild, create the two pinned checkouts and install with global vp; start both with T3CODE_DEV_SEED=0. Run seed.py to create a new timestamped run, then set capture.mjs/setup-app.mjs run paths and actual dev ports to that run. setup-app.mjs mints fresh local pairing credentials and writes private storage state locally; never upload those files. Run the named drivers against the fresh databases. seed-link-worktree.py creates the separate root/worktree link fixture before seed-links.mjs seeds its app project/thread. Native harness is controlled input only and must be applied independently to both disposable checkouts; mobile install uses the shared dev-client cache. Failed desktop iterations are included for audit, not represented as successful desktop verification.
### Cleanup and friction
Both disposable app servers, both Metro servers and the mobile HTTP/WebSocket proxy were stopped by captured PIDs. The iOS lease was closed. Disposable worktrees were removed; lead worktree was not used. Evidence and synthetic repositories stay in the one scratch directory.
FRICTION:
- tool | preview navigation timed out and viewport capture stayed 1280px after resizing | reliable exact-viewport capture with reduced-motion control
- infra | full desktop build pulled a web build and exceeded 600 seconds; native helper needed libsecret headers | documented direct package-build path and preinstalled libsecret development headers
- tool | actual Electron launch reached persistent Syncing messages despite isolated seeded state | working native environment auth/snapshot setup driver
- tool | device daemon intermittently unavailable; retry recovered; deeplink confirmations invalidated element refs | stable device daemon and fresh snapshots after each device action
- tool | embedded Browser certificate validation failed; baseline PR request could not reach GitHub | trusted network/certificate environment
- model | early still helper dismissed the intended toast; corrected and recaptured | dismiss incidental notices only during setup
- tool | ghdrop batch upload hit a transport error; smaller batches retried successfully | smaller default batches / transport retries
Model/harness: gpt-6.1-sol, Codex harness. No PR body or branch was modified by this evidence worker.
