Reconstruct repo from Claude Code + codex transcripts

Working tree (including .git) was lost to an rm. Rebuilt by replaying Write/Edit/
Read/attachment events from 25 Claude sessions and 22 successful codex apply_patch
blocks into one timestamp-ordered timeline.

Verified against ground truth recorded in the transcripts: wc -l on 10 files and
ls -l on 5 files at 2026-07-18T13:13:44Z both match exactly; 18 files are
byte-identical to their newest ~/.claude/file-history blob.

See HANDOFF.md for sources, gaps, and how to rebuild .venv.

+# Repository guidance
+
+## Video analysis
+
+When diagnosing render motion, transitions, timing, or visual artifacts, use
+`scripts/analyze_video_frames.sh` instead of manually seeking through the video.
+
+```bash
+scripts/analyze_video_frames.sh VIDEO [OUTPUT_DIR] \
+  --window START:DURATION [--window START:DURATION ...]
+```
+
+The script creates:
+
+- timestamped overview contact sheets sampled at 2 fps;
+- scene-change frames and a `scene-timestamps.txt` index;
+- optional dense 10-fps contact sheets for specified transition windows.
+
+Inspect the overview first, then request dense windows around transitions or artifacts. Sampling and
+scene sensitivity can be adjusted with `OVERVIEW_FPS`, `WINDOW_FPS`, and `SCENE_THRESHOLD`.
+
+The generated files are analysis artifacts and belong in `/tmp` or another requested output directory;
+do not commit them to the repository.
