# Issue 21821 — corrective evidence round 2

Issue [#21821](https://git.cafe/pingdotgg/t3code/issues/21821). Before [fef851bee0](https://git.cafe/pingdotgg/t3code/commit/fef851bee09102641061aeb78a3092c2ba2c72ab); after [67c9f4b5d8](https://git.cafe/pingdotgg/t3code/commit/67c9f4b5d8362d519f979f132282228b5c2f609e). This report supersedes the primary A/B capture claims in the original evidence report. The [published pass-2 audit](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/dfc3814b4324a11d/issue-21821-proof-pass2.md) remains the authoritative record of why those original captures failed acceptance.

W4 behavior: base two manual clicks fetch two distinct75-row pages, Worked1m15→2m30, opener absent. Head one click fetches eight sequential pages (75×7+7), exposes the agent opener and Worked8m52. Recordings include opener/Worked folds and return to newer turns. This is an evidence-only round: no implementation edits, tests rerun, pushes, merges, PRs, forge comments, native builds, or new fixtures.

Corrections to prior false or overstated claims:

- The original wide-light still pair was not pixel-identical:359 pixels differed by1/255. Its assertion and report claim were false. Every delivered pair in this round is checked on the exact copied PNGs and has zero differing RGB pixels.
- Original narrow expanded-opener captures were under the sticky fade; expansion alone did not establish an unobscured full opener. New expanded stills and recording states show the full text after a second scroll-to-top following expansion anchoring.
- Original narrow A/B composer deltas were not acceptable as a clean comparison. New primary narrow pairs have zero differing pixels in the bottom13%, with no masking. Composer bounds match in the stills. The same outer composer region is measured for both revisions: narrow CSS(x12,y742,w366,h50), wide(x480,y736,w736,h144). The original base390light DOM observation captured its1px-inset child rather than the outer element; composer-measure.json explicitly accounts for that and applies identical pixel bounds to both images. Narrow composer region differs by0 pixels; wide differs by1/light or2/dark pixels at1/255. We align the shared Worked/Completed run1 content: base scrollTop0, head16 CSSpx. The unchanged real glass composer then sees the same underlying content. This is actual scrolling, not an image edit or opacity override.
- MP4s below are ordinary links, correcting the original image-wrapper presentation. Original tooltip-contaminated ending stills, failure error clipping and recovered-opener fade remain limitations of the old supplemental package; they are not silently recertified here.

Environment: task worktree `/home/ubuntu/wt/issue-21821`; existing synthetic `.t3` projection DB, never reseeded. Machine fs-05/Linux; Chrome154 integrated web client through owned incognito T3 preview, local direct origin8102/server16142. DPR2, root16px, frozen Date1792840800000, fonts awaited, reduced motion plus animation/transition durations disabled. Exact CSS viewport is set before each fresh navigation:1440×900 or390×844, light/dark. Wide PNG tool outputs1280×800 full-frame scaled images; recordings2880×1800. Narrow outputs780×1688. Responsive web is not native mobile or Electron.

Only dev-origin IndexedDB thread cache is cleared between fresh bounded opens. The real earlier/fold buttons drive interactions. Pointer is parked on unused x1/y400, away from controls. Wide final captures close thread details using app controls to exclude unrelated branch/change-count UI; the sidebar remains visible after fresh navigation. All primary stills belong to their accepted recording's interaction state, with a second exact capture at least600ms later (wide650ms). No regions are cropped, masked, hidden or patched. Behavioral differences are the earlier-control/opener, Worked duration/time and navigator marks; shared later messages/composer are aligned. Unmasked wide subtraction also reveals small common-text rasterization edges and 51/light or 34/dark bottom-region pixels (maximum channel delta2/255); these are disclosed rather than masked. Narrow bottom-region subtraction is exactly zero.

Diff0 is absolute RGB difference amplified8× with saturation. DiffT is white where max channel difference is strictly>16/255. Both operate on the entire frame. Doubled text is subtraction, not ghosting in an original. All eight diffs and delivered stills were visually inspected. All658 encoded-video frames were reviewed at contact-sheet resolution in chronological sheets, including loading, expansion, collapse and final states; the frame index records counts. The primary acceptance statements concern completed states, not a promise of no transient loading frame.

## Matrix dispositions retained without scope expansion

A primary plain load: W4 corrected evidence above. B folds/scroll: opener and Worked expand/collapse, newer follow-up10/Completedrun11 reachable; usability of another earlier-history click after stopping before exhaustion remains unverified because this fixture exhausts. Fold recordings show grouped command counts, not inspection of all530 payloads. No visible duplicate opening/final assistant in inspected states.

C progressive merge/busy and K second-page failure/retry retain the pass-2 audit's accepted injected-gate proof from the old supplemental recording; no new C/K capture or naturally slow remote-client claim. Error URL clips and recovered-opener fades in that old package. O normal targeted find retains old normal-path proof (four matching-cursor conversation/full pairs); delayed activity and targeted runtime retry remain unverified. P literal two-run control retains old already-loaded/no-button fold proof; it is not a failing baseline. This corrective round did not repeat these supplemental flows or rerun tests; the prior39-test result is historical, not a new execution claim.

D: unit/source stop-before-exhaustion proof only; real-app older-run fixture unverified. E: human/queued boundary fixtures unverified. F: steer/promoted-steer fixtures unverified; A covers command-only continuation. G: any-notification stop predicate and regression have prior unit/source proof; real-app notification/mixed-activity shapes unverified. H: exhaustion without opener unverified. I: independent continuation flags and empty advancing-page edges unverified. J: reporter-shaped~900KB checkpoint/byte boundary unverified; this small-command fixture only covers row paging. L: first-page failure/disconnect unverified. M: replacement/deletion during follow-up unverified; targeted replacement tests are adjacent evidence. N: leave/remount/cancellation/persistence on follow-up unverified; cache resets are preparation only.

Q: actual Electron desktop unverified. R: native iOS and Android both unverified;390 web does not substitute. S: only local direct web verified; remote/relay/tunnel unverified. T: dormant citation callback is a source scope decision, no additional active production paging caller or runtime citation proof claimed. No new Settings/palette/keybinding, provider adapter, contract, server transport, protected mutation, agent tool or scheduled-task path is introduced by this two-file shared-loader change; no extra Cartesian capture matrix was attempted.

## Cleanup and FRICTION

Stopped every owned dev runner through retained session handles. Final socket query shows no8102/16142 listeners. Worktree restored clean to fix/issue-21821 at67c9f4b5d8362d519f979f132282228b5c2f609e. No implementation/scratch committed, no live DB writes; all scratch under/tmp/issue-21821-evidence-r2.

FRICTION — changing checkout under an active Vite session initially served baseline behavior after returning to head; that attempt was rejected, runner restarted, fresh head authenticated by eight-page trace. Startup readiness needed actual server availability, not Vite ready alone. Wide-light sidebar border settled across several tool captures despite no content motion; final capture8/9 exact equality was required. Initial wide recaptures exposed unrelated branch/change-count state in the details panel; rejected and recaptured with the details panel closed through UI; the sidebar remains visible. Narrow glass background required shared-content scroll alignment rather than hiding composer differences. Expansion anchoring must settle before scrolling the opener back into clear content. FFmpeg image output emitted timestamp-rounding warnings in the first exploratory full-resolution decode; final all-frame sheets use a microsecond encoder timebase and preserve every decoded frame.

Author:gpt-6.1-sol via Codex harness. No subdelegation. This report's primary A/B proof supersedes earlier primary acceptance claims; broader missing fixtures/surfaces remain disclosed.
