# Composer evidence: fresh followup

[#17892](https://git.cafe/pingdotgg/t3code/pulls/17892) · [#17892](https://github.com/pingdotgg/t3code/pull/17892)

BEFORE [eea98953](https://github.com/pingdotgg/t3code/commit/eea989536849e5b5049987ee24318b5a77326542) (main); AFTER [c772f425](https://github.com/pingdotgg/t3code/commit/c772f425b12ab22d7455d5de616370ece0d2a295) (takeover/pr-17892).

Original [NikitaMGrimm/t3code](https://github.com/NikitaMGrimm/t3code), fix/composer-compact-chip-order at [263670f2](https://github.com/NikitaMGrimm/t3code/commit/263670f2239d6118a60b4413c571fe8446d48627) is provenance, not a third captured build.

Status: original7/7 matrix rows retained per build, plus K1 desktop keyboard per build. Effective total18 raw stills and16 recordings;9 still pairs18 threshold diffs. Fresh work replaces4 raw stills and adds2 recordings; publishes14 images+2 MP4. Other prior captures preserved.

C2 Full and C4 Full are now clean at threshold zero outside the union of the actual chip/Attach controls. C2 changed0=1161/changed8=885; C4=1302/1022. Both outside-control counts=0. No unrelated composer-edge/sidebar/timeline/primary-action pixels. S3 prior pair is exact zero.

Scope: actual apps/web at desktop/responsive widths; no native Electron/mobile certification. Fresh Full retakes use Chromium148 software flags and viewport repaint; details in replay. No masking or DOM/CSS edits. Same isolated backend retained across final web-source switch to align update-discovery state.

## Claims and limits

Core Compact→Full Attach movement: BEFORE+33.15625px, AFTER0 on C1–C4. Original-node identity/input continuity and primary geometry are in geometry summary and retained trace. K1 actual keyboard order BEFORE Attach→meter→chip→primary; AFTER chip→Attach→meter→primary; reverse path also captured. Meter popover focuses Compact context; Escape returns to same trigger on both builds.

Chip absence is substantiated by actual chip:null and Resume thread on C3/C4. Prior desktop empty-draft narration overclaims absence and is corrected here. Narrow Tab collapses composer: no stationary narrow traversal claim.

Not captured: pending-question/choice-only Attach-hidden, queued edit, running Stop/Queue/Steer. No synthetic expansion of these optional branches. No code edits, commits, pushes, PR-body mutations or watches. Final branch clean; own server/browser/Xvfb/ffmpeg stopped.

## Friction

| Category | Happened | Avoidance |
|---|---|---|
| Raster | Matched focus/software flags alone left edge pixels | Same viewport repaint on both SHAs; assert zero outside actual control union |
| Backend state | Restart changed sidebar update indicator | Same backend while actual web source recompiles |
| Driver lifecycle | Stale page and overlapping retry damaged first AFTER clip | Global page after context preparation, finally-stop, full decode of replacements |
| Evidence accuracy | Desktop empty-draft label exceeded trace | Trust actual chip/action/focus; separate narrow absence from desktop traversal |
