# Caption-only correction: six real Kimi pairs

For [#24302](https://git.cafe/pingdotgg/t3code/issues/24302). These replace only the 12 affected narration clips from the [original evidence index](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/e81fc4c8cc5cc9e8/index.md). Four K1 wizard pairs and two narrow K3 saved-settings pairs. Desktop K3 was excluded. Screenshots and diffs remain unchanged.

Only the existing stale bottom caption was replaced, during its exact inspected frame range, with **“Cancel, then retry; buttons and terminal show current state.”** This instruction stays true across inactive Retry, active retry, fresh prompt and the second cancellation. No app/terminal/provider-output pixels were covered, cropped or altered.

Lossless H.264 qp=0; every original frame, PTS and exact track end preserved. Exhaustive decoded Y/U/V and RGB comparisons pass with zero tolerance: all app/terminal pixels are identical to the originals, and all pixels outside the repaired caption interval are identical. Encoded file bytes necessarily differ. Original public videos were retained and their SHA-256s verified by download; replacement public files were also downloaded and byte-verified.

Caption bounds in physical video pixels: original top y=1741 at 2880×1800, or y=1602 at 780×1688. Repair rectangle is strictly inside: x=0,y=1744,w=2880,h=56 or x=0,y=1604,w=780,h=84. The original boundary rows are preserved. The driver creates a fixed #111, white 12px monospace div with 8px padding.

**Timing:** host offsets below are UTC minus recording-start and approximate only. Media examples are actual decoded frame PTS, directly inspected; they show visible states, not certified click/onset boundaries. The capture/action logs show a 36-second initial wait after Sign in before observation. Original irregular recorder cadence remains unchanged. Visual checks used sampled full frames from every corrected recording, including caption transitions; exhaustive pixel/timestamp checks cover every frame. No uninterrupted-playback claim.

**Limit:** K1-1440-light-after preserves only about **1.015 seconds** of final inactive state in its source export (53.596267–54.611233s). Its final caption appears only in the last ~33ms. The host driver logged a 3.5-second wait, but that full hold is absent from this export; no extension was manufactured. The other 11 clips retain about 4.28–4.64 seconds from inspected final inactive state to original track end. This caption repair does not confer matrix acceptance. Real Kimi input, account completion, Windows, native mobile and native Electron remain unverified.

## Indexed sequence before each pair

K1 is the Add provider wizard authentication step; K3 is saved Provider settings. Start with the visible unauthenticated method, click Sign in, retain the initial observation window, then Cancel → inactive Retry → Retry sign-in → new attempt → Cancel → final inactive state. Before remains at Starting sign-in without terminal; after displays the actual Kimi authorization prompt. No noncredential input/account completion is claimed. K1 active/inactive footer states remain in the original action logs.

The manifest contains original → corrected URL mappings, SHA-256s, file sizes, exact replaced frame/PTS intervals, rectangle bounds, UTC action logs, direct media observations and RGB region hashes. The reproduction ZIP preserves the 12 originals, untouched prior metadata/driver, postprocessing and verification scripts, transition JSONs, sampled review sheets and dependency versions. Original source/still/diff links remain in the original index.

FRICTION: original export timing varies from host log offsets; the one short final hold is disclosed above. Initial caption-fix URLs were superseded after an auditor detected missing color tags. Final files restore original container/SPS color tags and pass exhaustive system-FFmpeg RGB comparisons. An initial mux end-duration discrepancy was also corrected; all final track ends match exactly. urllib public readback returned HTTP 403, resolved using curl; original and replacement downloads pass. No runtime captures, browser/server actions, checkout changes, commits, forge actions or merges. Publication used the ghdrop skill.
