# Evidence round 3 for PR [#33129](https://git.cafe/pingdotgg/t3code/pull/33129)

## What else changed — reviewer attention

The change affects visible behavior beyond its performance title. With the Browser URL field focused and `!previewFocus` bindings, before retains nine stale sidebar badges while after shows zero; the digit is correctly blocked on both. Moving focus to the composer restores eligibility and allows the same digit to navigate to synthetic thread 012. The independently matured modifier/context restoration behavior documented in round 2 remains part of the change: eligibility can restore immediately on head after terminal focus leaves or a model picker closes, while before starts a fresh 200 ms delay. This round does not remeasure those terminal/picker branches.

Every visible difference in this round:

- H9 focused URL field: exactly the intended nine badge slots change to their ordinary age labels (7,944 differing pixels, 2,111 above 16/255), plus the tiny raster residues listed next.
- At 1280×800, focus-blocked and focus-restored include 26 search/icon raster pixels outside the badge slots, max delta 19/255, two above 16. At 1440×900, open-blocked has that same 26-pixel residue; focus-blocked and focus-restored have three right-toolbar edge pixels, max delta 2/255, none above 16. No geometry or preview-content mismatch remains.
- H10's displayed instrumentation timestamps and measured sub-millisecond/low-millisecond scheduling differ. The synthetic row layout and hidden→visible behavior are the same. These digits are harness output, not product changes.
- H9 closed-held at both sizes and open-blocked at 1280×800 are identical at threshold zero. Only for those three pairs, nothing else changed.

Before [fa2f4ff](https://git.cafe/pingdotgg/t3code/commit/fa2f4ff2a2bac5ac92e07749f6b83b0003d642a0); after [12ac6ac](https://git.cafe/pingdotgg/t3code/commit/12ac6ac5cf5b0154b92af29fc82a45f4b1fa164b). This round supplies **2/2 requested recapture rows**, H9 and H10, with **six recordings, 20 settled stills, 20 diff images and 10 comparison sheets**. H1/H11 receive caption corrections only. Across rounds, **23/24 affected matrix rows have evidence at the disclosed scope**; P3 actual macOS Electron remains the accepted gap. X1 is exempt. This is not exhaustive coverage of every permutation.

[Round-2 complete index](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/465eea06831849af/evidence-index-round2.md) links round 1 and all other rows. [Corrected round-2 captions and trace chapter labels](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/dc72fd7842a20fc9/evidence-index-round2-corrected.md) is the same evidence with H1 light entries labelled **light** and H11 narrowed to **all-consumer teardown and clean remount after a matured hold and blur**. Pending-deadline cancellation and blur-independent last-unsubscribe reset are not established by H11. These corrections supersede the corresponding original captions; there is no recapture or new pending-timer claim.

## Conditions and reproduction

Linux x86_64; Playwright 1.60.0 / Chromium 148.0.7778.96, headless browser, no device emulation, DPR1, root 16px / 100% font scaling, dark and reduced motion. H9: 1280×800 required D plus supplemental 1440×900. H10: 1280×800 labelled HARNESS. These are real Vite app builds from the two specified checkouts. H9's inner browser streams the same synthetic fixture; only the app's Browser **URL-field** focus is claimed, not embedded page-input or Electron webview focus.

Fresh isolated server homes, T3CODE_DEV_SEED=0, twelve synthetic empty launched threads plus the app's unsent draft, no initial message and no agent turn. No real database copied or read. Data was seeded through the app RPC. Startup credentials, browser cookies and raw server/browser logs remain private. No app-source edits, tests, commits, pushes or PR-body changes.

Clock limitation: client Date is anchored to 2027-01-01T12:00:00Z and advances with performance.now() for production deadline hooks. Strict frozen Date is not satisfied; displayed age class stays stable. This is the same explicit exception as round 2.

Before every still: reduced motion, fonts ready, network idle, **no toast title remains**, neutral pointer, hidden caret, and two byte-identical screenshots 500ms apart. Initial loading, selection menus and the binding-change notification between chapters are setup in the recordings; all named interaction chapters begin after the notification disappears. The normal closed-panel thread-details card is product UI. Full surfaces only. Every still and diff was visually inspected in its full-surface pair sheet, with full-resolution spot checks; all six recordings were checked through 157 full-surface sampled frames on 15 sheets (H9 1-second cadence, H10 100ms around mount/visibility). This is sampled inspection, not uninterrupted playback.

Diff0 = absolute RGB delta amplified ×16 and clamped to 255 at threshold zero. DiffT = white where the maximum channel delta is **>16/255**. Per-pair JSON gives the exact pixel counts and bounding box. An earlier mismatched preview-stream frame was rejected; both 1440×900 recordings now include the same 1440→1442→1440 viewport settling sequence during setup, with the final stream at 539×775.

[Reproduction procedure](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/5a204777f220e600/reproduce.md) lists startup commands and driver order. Script links are below. Absolute capture paths and module imports should be adapted on another host. All uploaded data is synthetic.

## Evidence

### H9-D — 1280×800, dark

Real app; custom `mod+1..9` has no unconditional fallback. Start on 004 with a matured hold, open the Browser panel under `!previewOpen`, verify digit 1 cannot leave 004, then switch to closed route 003 and verify digit 1 reaches 012. Settle `!previewFocus`, return to 004, focus the actual URL field, verify the same digit is blocked, then focus composer while held and verify it navigates to 012. Browser URL-field focus only.

Before steps (seconds from recording start, startup alignment approximately ±1s; page markers are authoritative): 5.200s H9 !previewOpen: active 004, matured hold, open real Browser panel; 11.598s H9 current route without preview: 003 navigates under !previewOpen; 19.341s H9 !previewFocus settled; open preview on 004, browser URL-field focus only; 22.324s H9 focus composer with Control held, same digit navigates

After steps (seconds from recording start, startup alignment approximately ±1s; page markers are authoritative): 5.344s H9 !previewOpen: active 004, matured hold, open real Browser panel; 12.013s H9 current route without preview: 003 navigates under !previewOpen; 21.899s H9 !previewFocus settled; open preview on 004, browser URL-field focus only; 24.006s H9 focus composer with Control held, same digit navigates

### H10-HARNESS — 1280×800, dark

**HARNESS.** The settled F1→thread.jump.1 binding is compiled before mounting. The head imports production `useThreadJumpHintsVisible(keybindings, routeRef)`. Before imports its merge-base equivalent plus production modifier matching as Sidebar did. Other sidebar/composer consumers are unmounted on Welcome. Synthetic rows are the only rendered list. Driver coordination mounts the first hook host at a trusted F1 keydown; both events are separately logged and displayed. F1 does not itself change modifier state or reset the production deadline. The first host commit is hidden; visibility follows ~200ms later. A later F1 remains visible, demonstrating that mount/subscription is the timer boundary.

Before steps (seconds from recording start, startup alignment approximately ±1s; page markers are authoritative): 6.394s H10 already-settled F1 binding: first subscriber mount, immediate trusted F1, hidden until initial 200ms deadline; 8.514s H10 later F1 is not a modifier change: visibility remains true

After steps (seconds from recording start, startup alignment approximately ±1s; page markers are authoritative): 6.979s H10 already-settled F1 binding: first subscriber mount, immediate trusted F1, hidden until initial 200ms deadline; 9.067s H10 later F1 is not a modifier change: visibility remains true

## Remaining scope / unverified

- **P3 actual macOS Electron / Command**: unavailable on this Linux host; the accepted gap and supplemental Linux Electron material remain in rounds 1/2. No desktop recapture was requested in round 3.
- **Strict frozen Date**: unmet, for the production deadline-clock reason above.
- **H9 Electron webview and embedded page-input focus**: not claimed; this round directly covers Browser URL-field focus only.
- **H10 boundary harness**: coordinated first mount on F1, not a claim that pressing a no-modifier shortcut starts a new delay in an already-mounted app. Live binding updates/mismatch/release remain covered by round 2.
- Original scoped limits remain: unchanged provider/status/icon permutations, every Settings picker host, scope/sort/history/selection variant, pending/error/retry chrome, drag/sweep/rename permutations and unavailable capability cases were not all multiplied into captures. Round-1/2 per-row limits remain authoritative. No direct native mobile, remote/relay/tunnel or paid-provider pass is claimed.

Cleanup: all 50 recorded driver/browser/fixture/runner/Vite/server PIDs are gone; owned ports 6031, 7035, 28861, 28862 and 31291 are closed. The before worktree was removed. The after checkout remains clean at the requested head. Raw private logs and rejected captures remain in scratch, not uploaded. No owned shared-preview tab was created.

tool | preview rejected an about: URL; agent-browser CLI was absent | use the brief's existing Playwright drivers with the returned preview error recorded
runbook | old toast selector did not match the current toast component | wait for all data-slot=toast-title elements to disappear; reject the initial take
runbook | overlapping experiments changed keybindings and collided on the synthetic fixture port | serialize runs per environment and shared fixture; failed takes excluded
infra | initial 1440 preview stream retained different frame sizing after route restoration | identical resize settling sequence and canvas-size confirmation before accepting the pair

AI-assisted; verified with the tests and tools listed above.
Cleanup complete; no owned process, browser tab or second worktree remains.
