# Round 2 evidence for [#33042](https://git.cafe/pingdotgg/t3code/pull/33042)
AI-assisted; verified with the tests and tools listed above.
Before: [4c36119](https://git.cafe/pingdotgg/t3code/commit/4c361199f47f6ea32a2c14835df392640d0f7c63); after: [28ee80f](https://git.cafe/pingdotgg/t3code/commit/28ee80fa3a26b4663950345034f971887d0ad2f8). Real application from each commit's own checkout, separate fresh synthetic server databases. No PR body edit, commit or push. Only requested round-2 rows are included; accepted round-1 rows were not redone.
**Coverage: 5 of 7 requested matrix row IDs have new captures: C04, A17, A12, A13, A09 (8 still pairs and 3 recording pairs).** C04 uses a real server-persisted watch on an unresolved synthetic target; remote forge integration is unverified. A13 is an explicit bound-child projection harness. A01 native is blocked by tooling; A15 is unreachable for the ordinary never-ran import flow, with broader historical cases unverified. This is not a claim of complete native or full remote-watch coverage.
Rendering environment for every WD/WN capture: Linux x86_64 fs-52, Chromium 157.0.0.0, zoom 1, DPR 2, en-US, UTC. **WD = 1440×900 CSS pixels, dark, 2880×1800 PNG. WN = 390×844 CSS pixels, light, 780×1688 PNG.** WN is responsive web, not native. Default app fonts, interface/composer/code 16/14/13px. Whole surface, no cropping. Clock 2026-11-10 09:00 UTC except A09's declared 10:10→10:11 fixture. A13 alone freezes CSS motion. All 16 final endpoints have pixel-identical second captures 500 ms apart; [verification.json](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/90f8aef5fc1742f0/verification.json) and [verify.py](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/fcb343d140ce9f0a/verify.py) record/check them. All accepted stills, diffs and recordings were visually inspected. Diff0 amplifies any nonzero RGB-channel delta to 255; DiffT16 amplifies channel deltas greater than 16 to 255. Black diffs mean zero changed channels at that threshold. Each cell lists its source commit(s) and the image's SHA256.

## A01 native — tooling blocker; no pair
iPhone 17 Pro could not open: `Error (COMMAND_FAILED): Remote daemon is unavailable`. Its immediate retry was only 31 seconds later, a deviation from the requested minute. Pixel 9 fallback installed and launched, but pairing failed with `Error (TOOL_MISSING): adb not found in PATH`; retry more than a minute later failed identically. Native work stopped, lease closed, Metro stopped. No settled/import/un-settle native evidence is claimed. Exact sequence, diagnostic identifiers and cleanup: [native-blocker.md](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/dbe7a7ed0c5f4b18/native-blocker.md).
## C04 — watch exception in fully loaded projection (WD dark)
Normal app/server `thread.pull-request.watch`, persisted by the server; **no shell projection injection**. Target is intentionally unresolved synthetic `evidence.invalid / synthetic/fixture / 1`, so this does not verify external PR check sync. Both loaded projections contain 0 runs, 2 imported messages and 0 provider sessions. Actual deriveThreadStructureRuntime returns idle on both while watched; unwatch returns idle before versus null after. See [watch-transcript.json](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/d17133fe5257213c/watch-transcript.json) and [watch-scenario.js](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/9f173a0db6e82c9a/watch-scenario.js). An exploratory watch of the green real PR auto-woke a different synthetic thread and attempted an unauthenticated provider start; it was stopped/deleted and appears in no accepted asset. A stable ongoing watch of an actual external PR was therefore not captured.

What else changed: zero pixels; opened history and composer remain identical.
## A17 — remove watch without stale tooltip (WD dark)
Recording steps, relative timestamps: 0s watched Waiting endpoint; approximately 2s normal server unwatch; approximately 4s explicit shell-subscription refresh; by approximately 6s after leaves Working and shows age 3h, while before remains Waiting. Pointer stays off the row; no stale tooltip. End approximately 10s. The fully loaded projection updates through the command; **automatic sidebar push latency remains unverified because this fixture required subscription refresh**. The linked synthetic PR badge remains after unwatch.

What else changed: only sidebar shelf membership, row location/background and Waiting/age label; history, composer and detail capsule unchanged. Diff bbox in physical pixels: (16,204)–(494,1626).
## A12 — opened imported history + composer, reproducible presentation fixture
No auth banner and identical composer controls on both builds. **Synthetic ready/authenticated provider presentation** is installed in client state; no real CLI authentication is claimed. [bootstrap.js](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/1caf4b213583bca4/bootstrap.js) embeds every health/capability field and the complete [client-settings.json](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/5db00cafb69732f4/client-settings.json). [seed.py](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/5932e85342a2c6d4/seed.py) generates the identical two-message transcripts. [setup-fixture.js](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/7ef5dbc70db40714/setup-fixture.js) records the normal server import/un-settle setup commands. See [workflow.md](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/07a19e1dee5a2bb8/workflow.md) for viewport/theme, fonts, sidebar/capsule state, branch/workspace, clock, provider descriptor, model options and exact reload ordering.
The reloaded and rebuilt A12 presentation matched the original pixel-for-pixel in all four build/profile combinations: [rebuild-check.json](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/21919b0272bd97bc/rebuild-check.json). Rebuild images and their 500 ms checks are in [uploads.md](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/0864d098e1d21472/uploads.md). This repeated the presentation after reload on each existing isolated server, not a second fresh database run.

## A13 — bound native child with zero runs, PROJECTION HARNESS (WD dark)
Explicit synthetic projection harness, not a real provider turn. Uses the real makeSubagentChildThread helper, provider creation source, agent creator, parent lineage, non-null activeProviderThreadId, Codex provider-thread binding with a synthetic parent-session id, and a running root activity whose runId is null/countsForRun false. No runs, messages or provider sessions. Corresponds to the adapter's empty started activity path; opens read-only. Actual shared runtime changes idle→null across builds, while native-child status remains correct. Fixture and all bound fields: [native-child-harness.js](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/ce66b21b2d3f8e4b/native-child-harness.js). CSS motion is disabled for this harness only; details capsule is closed on both sides.
Recording steps: 0s opened Thinking child (15s age); approximately 2s harness changes the root activity to completed; by approximately 3s both clients show Completed in 15s; end approximately 4s. No provider was invoked for the child harness.

## A09 — snooze expiry and real Dismiss acknowledgement (WD dark)
Recording steps: 0s snoozed fixture, browser time 10:10 UTC, deadline 10:10:05; approximately 2s **explicit browser-clock jump to 10:11 and shell-subscription refresh**; by approximately 3s before shows Working/Waiting, after shows Woke. At approximately 7s click the visible Dismiss in the Woke-from-snooze footer; approximately 9s refresh the shell subscription; after now shows age **4h**, before remains Waiting. Footer gone on both; end approximately 12s. This is the literal recorded acknowledgement, not an opening gesture. It is a controlled clock/refresh fixture; natural wall-clock scheduling latency is unverified. Scripts: [clock-snooze.js](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/05771a63a9391705/clock-snooze.js), [refresh-shell.js](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/5aeae6cf6ecfa9b0/refresh-shell.js), [scenario-driver.js](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/53f66038854981bb/scenario-driver.js).

What else changed: only sidebar Waiting versus age 4h and shelf membership; footer gone, history/composer unchanged. Diff bbox for both A09 endpoints: (16,204)–(494,1626) physical pixels.
## A15 — unreachable in ordinary never-ran import; no fabricated pair
[Code-backed reachability assessment](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/a9e1973fddc99a6b/a15-reachability.md): the importer creates a stopped runtime and provider-thread session id null; the production provider-session open occurs in run start after run/attempt guards. Ordinary import → un-settle alone cannot generate the proposed stale provider-session error without starting a run. Marked **unreachable for that flow**; broader historical/migrated/bound-child error combinations remain unverified. No A15 pair is claimed.
## What else changed, scope and cleanup
Within paired endpoints, differences are confined to the sidebar. C04, narrow A12 and both A13 endpoints have zero changed pixels. Between scenarios, A17 retains a synthetic linked PR badge, A12/A09 unlink it, A13 intentionally replaces ordinary imported history with an empty bound child plus settled parent, and A09 deliberately changes the clock. Those are declared fixture differences; no before/after pair changes transcript.
Only web is captured. Desktop/Electron and native iOS/Android are unverified in this round. The mobile pool failure is not treated as a pass. Remote forge synchronization and automatic shell subscription latency are unverified. No tests or CI were rerun as part of this evidence-only round; checks/reviews not assessed. Server state, provider config and transcripts are synthetic and isolated; no installed userdata was seeded/read/modified. Original diagnostics containing private routing/auth data were excluded from upload.
Cleanup verified: owned dev servers, Metro and proxy stopped; lease and all owned tabs closed; before checkout removed; after checkout has no .t3 state and clean git status at the requested head. All evidence stays in scratch. [cleanup.json](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/c3de50cb73923b54/cleanup.json).
FRICTION:
- tool | iPhone remote daemon unavailable; Pixel pairing reports adb missing even after the minute-spaced retry | working pool daemon and agent-device pairing tools on the device host.
- runbook | initial iOS retry was 31s, not the requested minute; Android fallback retry met the interval | enforce a timed retry before the second attempt.
- tool | shell subscription needed explicit refresh in watch/snooze fixtures | deterministic subscription delivery or a documented refresh hook; no automatic-delivery claim here.
- tool | dev-runner termination left child servers; initial worktree removal left a directory-not-empty remnant | process-tree shutdown propagation; exact verified children were stopped and own remnant removed.
