# Evidence for [#21789](https://git.cafe/pingdotgg/t3code/issues/21789) [Public evidence index](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/6353d09f1e0de8db/index.md) · Exact upload results: `/tmp/issue-21789-lead/upload-results.md`. 23 BEFORE/AFTER recording pairs (46 videos) cover V1/V2, I1–I13, and added R1/R2. Every interaction row has recordings; stills below are supplemental comparisons. Row I11 has an unavailable native-menu subcase, and R2 has controlled-animation timing, both qualified below. No public forge writes, PR, push or merge. Baseline: immutable [8d3b061121](https://git.cafe/pingdotgg/t3code/commit/8d3b061121).

Repeat seed, empty seed, Python compile, active-server refusal verified. Fixture only seeds UI projections; no backend/event-history claim. No private messages copied or provider turns run.

Metadata pin/unpin commands retain real backend timestamps; affected Gamma relative label becomes now in both R1 takes. Current orderAlpha/Beta/Gamma; legacyGamma/Beta/Alpha. Environment UUID differs between homes and is not visible. Default native Linux Ctrl+digits; web overrides Ctrl+Alt+1/2/3/9 with !modelPickerOpen; browser stock digits remain browser-owned. Real app surfaces: web through T3 preview tools in owned tabs; real headless Linux Electron using the custom t3code-dev://app origin and native CDP key input. BEFORE renderer7960 is immutable baseline, AFTER7107 is candidate. Same desktop/backend bundle (no backend changes), restart to switch renderer. No synthetic KeyboardEvent used.

T3 snapshot transfer downsizes1440 frames to1280×800; narrow DPR2 screenshots are780×1688; native ElectronDPR1 screenshots use CSS pixel dimensions. No screenshot crops or masking in comparisons. Pointer overlays are hidden for raw stills; videos retain input annotations/cursor. Diff method: absolute RGB channel difference, zero threshold (`max(abs(RGB))>0`), amplified×8 with saturation255, and separate stated threshold `max(abs(RGB))>16/255`. No tolerance applied to the zero count, no pixels excluded. Raw PNGs preferred; two desktop pairs without raw endpoint stills use decoded final video frames and are explicitly marked. Pixel metrics are supplemental, never substitutes for interaction recordings.

I11 default native shortcuts, collapse, rail, and narrow shell are recorded before/after; native sidebar menu subcase is unavailable because no item exists. R2 unfinished200ms close across768 is recorded before/after with controlled animation time; natural wall-clock sub200ms cadence is unverified. Both baseline and candidate pass R1/R2; these prevent regressions introduced by retaining hidden children, not failures expected in the older unmounted baseline. Native iOS/Android untested: their separate React Native sidebar does not import this web primitive. macOS Cmd and Windows Electron untested: native shell run was Linux Ctrl. Production-hosted app.t3.codes, relay/tunnel, multi-environment/multi-device, OS-native menus absent from this build, and provider permutations were not exercised; no transport, backend/provider or contract change. Unused primitive variants (right/top/bottom, floating, icon, inset, none) have no production caller. No command-palette sidebar-toggle caller exists; palette tested only as shortcut arbitration. No exhaustive row-reorder animation smoothness/performance profiling beyond the recorded R1 sequence. ## Runtime handoff Closed both owned T3 preview tabs and dedicated issue21789-capture agent-browser session. Stopped every runtime started during capture, including BEFORE16000 and AFTER Electron/backend15147/CDP19389. Inherited Vite servers7107 and7960 remain for lead shutdown; worktrees retained. No live ~/.t3 database server/write, no process killing by pattern. The lead may resume browser/desktop ownership after this handoff. ## FRICTION - Inherited PTY session IDs were not usable in this harness. Port owners and /proc cwd were checked before replacing task-owned backends/Electron; later sessions were captured and stopped directly. - First Electron encoder attempt at60fps fell behind; discarded. Accepted native videos are30fps. Cached npx agent-browser binary used in its dedicated session. - Natural close→resize operations crossed after the200ms transition because renderer/automation work exceeded the window. Several attempts were discarded from accepted evidence. Controlled CDP animation playback validates the unfinished-close lifecycle deterministically; natural cadence remains unverified. - Initial screenshots could race app loading despite awaited navigation. Added explicit thread-header readiness and replaced affected takes. No splash frames are used as accepted static comparisons. - Legacy uses reverse visible orderGamma/Beta/Alpha; corrected paired sequence and replaced baseline/candidate takes. - Plain composer remains contenteditable; terminal is Ghostty Terminal input, not an xterm selector. Used actual focused elements; no synthetic keyboard events. - Keybinding capture auto-saves the unchanged binding; subsequent Escape does not prove cancellation. Labeled above. - Browser default numeric shortcuts are desktop-gated by design. Explicit overrides plus real Electron defaults avoid false browser-default failure claims. - Pointer hover and caret persistence differ when nodes remain mounted; full-frame diffs retain and enumerate these effects instead of masking them. Encoded frame comparisons have compression noise. - Automatic empty-workspace bootstrap initially added a fourth row; corrected with T3CODE_AUTO_BOOTSTRAP_PROJECT_FROM_CWD=false and reseeded while stopped. Accepted fixtures contain only the stated synthetic rows. - An immediate Electron restart briefly found its backend port still shutting down; waited for release and restarted. Fixture refuses to seed while runtime PID remains live. - No native Sidebar menu item exists; that subcase cannot be captured honestly. No browser or shell substitution is claimed for untested OS/native mobile surfaces. Work performed with GPT-6.1-sol through the Codex harness; capture used test-t3-app, agent-browser, and [ghdrop skill](/home/ubuntu/.codex/skills/ghdrop/SKILL.md). ## Final artifact validation All314 then-published URLs returned HTTP200 with curl. [Exact link checks](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/0ed1dfa797433ced/public-link-validation-curl.json). All46 videos fully decoded with exit0. [Exact decode results](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/4ead8407f1d0f62a/full-video-decode-validation.json). The36 original T3 preview MP4s emit duplicate/nonmonotonic DTS warnings at FFmpeg’s null-output muxer;10 Electron WebMs do not. Original captures are preserved, without retiming/re-encoding. Timestamp annotations are approximate driver elapsed times, including recording-start handshake and automation overhead. Additional FRICTION: Python urllib HEAD returned403 on the same public URLs where curl returned200; curl verified every link. FFmpeg timestamp warnings above are retained as a capture-tool limitation, not hidden as a clean mux validation.
