Board repeat after source-timestamp fix

The actual DSI-1 568x1232 RGB565 Pixman session ran package /nix/store/iyxcmrirznbl45ggzx6y4i42kp1wybzv-k230-card-shell, source b88c4cc65af9274ea5ed0fb43619eefbf6a65396, with the same 24-drag-per-count native injected acceptance harness as ../../board-cost/long-trace/. The archive transferred over Wi-Fi with matching SHA256 before extraction.

All thirteen interaction checks were OBSERVED, including upward throw, client refusal, separate timeout, accepted close and existing shell controls. interaction-checks.json preserves those check rows; its raw collection status remains CAPTURED_REQUIRES_REVIEW. This one successful repeat supports the fixed path but is not proof that every real-finger throw is reliable. New screenshots are not separately accepted here; prior reviewed native visual evidence remains in ../../injected/. The old failed throw and old-clock negative control remain committed and are not superseded with passing claims.

Cost reproduction (expected exit 1, FAIL):

python3 tools/card-shell-benchmark.py --board \
  --input docs/evidence/card-shell/touch-timestamps/board/telemetry.log \
  --manifest docs/evidence/card-shell/touch-timestamps/board/manifest.json \
  --output /tmp/card-source-time-cost.json

One/two-card coverage is 143/138 submitted frames and 90/90 tracking intervals, above the fixed 60/30 minima. There are no unresolved correlations or missing provenance fields. This is not a performance pass or an established speedup.

The experiment restored the original shell and seatd services. No image flash or reboot occurred. Independent normal-control verification is in restoration.json. Task 4.2 remains open: rendering/update work must improve independently of this recognition fix. The existing dispatch-based telemetry and all cost thresholds are unchanged. Backend presentation is not optical visibility, sampled memory cannot rule out between-sample peaks, and injected input is not physical-finger acceptance. Default image integration remains gated.
