# W9 · round2 evidence
Before [15707a84](https://git.cafe/pingdotgg/t3code/commit/15707a84b03e27bb257d60e027812ebf94bbda25); after [597f1aea](https://git.cafe/pingdotgg/t3code/commit/597f1aea6191d434ad23877e0e94121b7858382e).
VM fs-11, Linux x86_64; Chromium 156.0.8078.70; no device emulation; DPR 2; font scaling 100%, root 16px; CSS viewport 1440×1000. The original Browser panel refused connections twice, so local Chromium 156 uses Playwright/CDP. Whole-viewport PNGs are 2880×2000; movies are 1440×1000, captured by timed CDP screenshots at approximately 10fps with variable frame durations. Reduced motion is emulated as reduce; fonts and browser network idle are awaited. Each accepted still matches another capture 500ms later. Video stills are paused at a deterministic source frame. The harness native boundary is rendered in this desktop browser; no native device or mobile emulation is claimed.
**What else changed — round 2:**
- W2 fullscreen and all eight W9 controls: zero changed pixels at threshold 0 and >8/255. Nothing else changed in these settled pairs.
- W10: only the harness repository diagnostic changes from `(absent)` to `fixture-org/media-upstream`. The two production media resources follow the selected environment in both revisions. M2: only that same repository diagnostic changes on each page. `(absent)` is a display sentinel, never a field/value sent by base code; raw transcript resource objects show the true omission. These diagnostic text changes are intentional evidence of this PR, not product layout changes.
- Recordings have small action/capture timing offsets and different playing video clock/pattern frames; both use the same scripted sequence. The captions below report per-side times. W10 starts with about1s of the default controls scene before selecting E1, and its video-loading indicator can appear while each scene mounts. These transient intervals differ between runs; settled frames contain no loading indicator. The clips do not establish frame-exact performance equivalence.
- Round 1’s declared transient loading/spinner, cursor/tooltip and capture-offset differences remain recorded in its retained rows. Its earlier fullscreen exclusion and the four missing subcase flags are replaced by this round’s evidence.
Diff0 saturates every nonzero channel delta to255, including a one-level change. Diff >8/255 highlights channel deltas strictly greater than8. All18 new pairs settled.

**W9 — unrelated media/chips and unknown-card controls, completed in round 2**
**Labelled production-component harness; asset hooks are a request boundary stub.** Same PR repository is deliberately in context for every scene. Relative image, absolute workspace video and workspace audio emit only `media-file` resources with threadId/path, with no repository. Host-file image uses HostImageUrlContext directly; hosted direct audio uses its original URI and no resource; file/context chips emit no media resource. The unknown-card scene injects only an otherwise unreachable unknown segment into the production splitter result and mounts the actual attachment-card branch; no media signing request. All eight controls match at zero threshold. Round1’s existing legacy/gate controls are retained in its producer recording.
**Same sequence:** 1 relative image; 2 absolute workspace video; 3 host-file image; 4 direct hosted audio; 5 workspace audio; 6 file-link chip; 7 context-reference chip; 8 injected unknown card. Action and completed-observation times:
**Before:** 1.002s action → 2.328s observation control 1; 3.829s action → 5.152s observation control 2; 6.696s action → 8.014s observation control 3; 9.487s action → 10.816s observation control 4; 12.492s action → 13.820s observation control 5; 15.346s action → 16.663s observation control 6; 18.361s action → 19.676s observation control 7; 21.144s action → 22.464s observation control 8.
**After:** 1.001s action → 2.336s observation control 1; 3.884s action → 5.216s observation control 2; 6.773s action → 8.090s observation control 3; 9.561s action → 10.885s observation control 4; 12.369s action → 13.689s observation control 5; 15.190s action → 16.517s observation control 6; 17.981s action → 19.293s observation control 7; 20.814s action → 22.139s observation control 8.
