# Final evidence index — issue 17674 This index selects the final evidence and supersedes the original pixel-diff-report.json and stale C25-390-light derived comparisons under /tmp/issue-17674-evidence. All final derived comparisons come from /tmp/issue-17674-closure/pixel-diff-report.json and its 51 corresponding absolute/x8/threshold images. Drafts and all claimed C3 Before/After comparisons are excluded. C3 After is a supplemental threshold control only. Retained core C1 Before: [70e5e384da](https://git.cafe/pingdotgg/t3code/commit/70e5e384da). After: [82f820bb7e](https://git.cafe/pingdotgg/t3code/commit/82f820bb7e). The two production blobs are byte-identical to final head [68e33d0f7c](https://git.cafe/pingdotgg/t3code/commit/68e33d0f7c); Before affected files match the current merge-base. These are recorded revision attributions, not independently attested served SHAs or whole-application equivalence. Supplementary captures span intervening main merges; do not relabel them as final HEAD. Environment: Linux Chromium through T3 collaborative Browser, real isolated web dev app, seeded fixture and controlled delivery of real per-file requests (HARNESS for timing). CSS desktop 1440×900, responsive 390×844, DPR2, default font scaling, light/dark. Inherited desktop endpoint PNG raster is 1280×800 despite CSS metadata; original desktop video is 2880×1800; annotated video is 1440×1030 including caption area; responsive endpoints 780×1688. Clock freezing was imperfect; whole-surface diffs include unrelated sidebar/composer/panel geometry/text drift. They are raw differences, not regression measurements. Captioned core videos are annotations of C1 source videos, not fresh captures. Source/timing: C1-before/after-1440-light.mp4 in the original evidence directory; C1-before/after-timing.json and captions.srt in closure. Relative performance.now timestamps are approximate. Before: collapse ~0.99s, release ~1.16s, reopened added file ~9.05s, expand ~20.56s. After: collapse ~0.74s, release ~1.02s, preserved folds ~6.04s, expand ~16.85s. Individual toggles occur between endpoint and expand. Matched control: same-coordinate crop [96,184,780,568] from C1 responsive-dark pair, six unchanged modified-file headers, 684×384, no registration/masking/resampling, zero changed pixels of 262656. Zero difference applies only to this region. Full originals and amplified differences are below. Threshold is max RGB channel >16/255; zero-threshold amplification is ×8. Publication: linked files below are uploaded. Unlinked timing/source metadata, remaining 51 comparisons and supplemental original artifacts remain local. This index does not claim every inherited matrix row was uploaded or verified. Missing old paired threshold/control rows and native Electron verification remain disclosed limitations; no CSS, server, contract or mobile path changed. ## Selected published assets - [C1-before-captioned.mp4](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/2909a124cea0d9bd/C1-before-captioned.mp4) - [C1-after-captioned.mp4](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/02e4db138d13012e/C1-after-captioned.mp4) - [control-before-after.png](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/2ba725ce97e86421/control-before-after.png) - [control-modified-headers-amplified-diff-x8.png](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/d81256b474ded9c7/control-modified-headers-amplified-diff-x8.png) - [control-modified-headers-threshold-diff-16.png](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/7081299d9ca389dc/control-modified-headers-threshold-diff-16.png) - [C1-before-1440-light.png](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/337d1614d5e96c27/C1-before-1440-light.png) - [C1-after-1440-light.png](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/a784f1bc8f632f08/C1-after-1440-light.png) - [C1-1440-light-amplified-diff-x8.png](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/36723e8bf5cfd58e/C1-1440-light-amplified-diff-x8.png) - [C1-1440-light-threshold-diff-16.png](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/1cb9ec9ea4674687/C1-1440-light-threshold-diff-16.png) - [C1-before-1440-dark.png](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/3a0c7df34f392a28/C1-before-1440-dark.png) - [C1-after-1440-dark.png](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/850ca79c7b8df1b4/C1-after-1440-dark.png) - [C1-1440-dark-amplified-diff-x8.png](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/989b84372562b105/C1-1440-dark-amplified-diff-x8.png) - [C1-1440-dark-threshold-diff-16.png](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/cb281e91666a4d64/C1-1440-dark-threshold-diff-16.png) - [C1-before-390-light.png](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/98685c85c43d6f9b/C1-before-390-light.png) - [C1-after-390-light.png](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/392f4462b08b7c93/C1-after-390-light.png) - [C1-390-light-amplified-diff-x8.png](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/84b46bac01ce7137/C1-390-light-amplified-diff-x8.png) - [C1-390-light-threshold-diff-16.png](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/ba8dd8276d602b52/C1-390-light-threshold-diff-16.png) - [C1-before-390-dark.png](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/0651076bd530569d/C1-before-390-dark.png) - [C1-after-390-dark.png](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/43bf0b98639f687c/C1-after-390-dark.png) - [C1-390-dark-amplified-diff-x8.png](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/20a01a71330a8ba0/C1-390-dark-amplified-diff-x8.png) - [C1-390-dark-threshold-diff-16.png](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/2528e9a066a42c9d/C1-390-dark-threshold-diff-16.png) - [C3-after-1440-light.mp4](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/24e0b7624c647371/C3-after-1440-light.mp4) - [C4-before-1440-light.mp4](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/6092aa6fe4bb9b56/C4-before-1440-light.mp4) - [C4-after-1440-light.mp4](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/16c54c4896f35461/C4-after-1440-light.mp4) - [C6-before-1440-light.mp4](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/bc1f148408dedbfb/C6-before-1440-light.mp4) - [C6-after-1440-light.mp4](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/22f13663c19d7060/C6-after-1440-light.mp4) - [C7-before-1440-light.mp4](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/1ecee59881653962/C7-before-1440-light.mp4) - [C7-after-1440-light.mp4](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/e4a6bf35a70ebe9b/C7-after-1440-light.mp4) - [C25-before-1440-light.mp4](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/cebf52a5cdc3ef3b/C25-before-1440-light.mp4) - [C25-after-1440-light.mp4](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/4683fb5651c82e0b/C25-after-1440-light.mp4) - [pixel-diff-report.json](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/1ee5b6b073beee11/pixel-diff-report.json)
