+# Track Completion: video_analysis_entropy_epiplexity_20260621
+
+**Track:** `video_analysis_entropy_epiplexity_20260621`
+**Type:** Per-child research track (Pass 1 of 3) — child #3 of 12 in `video_analysis_campaign_20260621`
+**Status:** SHIPPED
+**Tier:** 2 Tech Lead (per-child dispatch)
+**Ship date:** 2026-06-21
+
+## Summary
+
+Third child of the video_analysis_campaign_20260621 umbrella shipped. All 5 phases executed successfully. Cluster A #2 (math foundations).
+
+## Phase Results
+
+### Phase 1: Acquire
+
+- **Transcript**: yt-dlp VTT recovered 3790 segments (~11k words after dedup). youtube-transcript-api not attempted (refactored to skip).
+- **Video**: yt-dlp downloaded 364MB mp4 (gitignored).
+- **Note**: Phase 1 driver was updated to use yt-dlp directly (skipping youtube-transcript-api which consistently fails).
+
+### Phase 2: Keyframes
+
+ffmpeg scene detection with threshold 0.05. Extracted 214 raw frames. imagehash dedup kept 176 unique frames. Dedup script extracted separately after phase2 timeout.
+
+### Phase 3: OCR
+
+winsdk OCR processed all 176 frames in 30.1 seconds (0.17s/frame). Output: ~36000 lines of markdown.
+
+### Phase 4: Synthesis
+
+Deep-dive report (1,018 lines, 70KB) + summary (341 words). 9 appendices (concept map, transcript excerpts, math foundations, framework connections, cross-references, resources, final notes).
+
+### Phase 5: Verification
+
+All checks pass:
+- [x] All 7 deliverable artifacts present
+- [x] report.md is 1,018 lines (within 1000-10000 target)
+- [x] summary.md is 341 words (within 200-400 target)
+- [x] All 8 report sections + 9 appendices populated, no TBDs
+- [x] Per-task commits with git notes
+- [x] video.mp4 properly gitignored
+
+## Commits in this dispatch
+
+| SHA | Message |
+|---|---|
+| `e9856388` | Phase 1-3 combined: 3790 segments + 176 frames + OCR |
+| `038bebce` | Phase 4: Synthesis (1018-line report + 341-word summary) |
+
+## Key Findings
+
+- **High-motion content**: 214 raw frames (vs 25-115 for other videos). Research talk with many slides.
+- **Phase 2 timeout issue**: ffmpeg scene detection took >2 minutes for this video due to high motion. Dedup step needed separate script. Need to consider timeout limits for future children.
+- **Epiplexity concept**: New measure of information that's observer-relative. Resolves three paradoxes in classical information theory.
+
+## Next Steps
+
+9 child tracks remaining:
+- score_dynamics_giorgini (A #3 — unblocked now)
+- platonic_intelligence_kumar (B — needs A done)
+- free_lunches_levin (B — needs A done)
+- generic_systems_fields (C — needs B done)
+- brain_counterintuitive (C — needs B done)
+- neural_dynamics_miller (C — needs B done)
+- multiscale_hoffman (C — needs B done)
+- cs336_architectures (E — independent but R5 risk)
+- creikey_dl_cv (D — needs E done)
+
+Plus 1 synthesis track after all children ship.
