Rolling-caption dedup (longest-common-prefix algorithm) produced 1485 unique clean segments (46.5KB plain text). +- **Video:** yt-dlp downloaded 178MB mp4 in Matroska/WebM container (format 400+251). Required direct `yt-dlp` call (the `download_video.py` script's `scripts.video_analysis.error_types` import fails when run as a top-level module; the umbrella phase1_acquire driver had the same issue — fell back to `uv run --with yt-dlp yt-dlp ...` directly). +- **Cleanup:** improved `clean_transcript.py` driver added to `scripts/tier2/artifacts/video_analysis_campaign_20260621/` (rolling-caption dedup handles triplicate repeated text from yt-dlp auto-subs). + +### Phase 2: Keyframes + +ffmpeg scene detection at threshold 0.05 (low-motion math lecture). 91 raw frames extracted; imagehash phash dedup kept 31 unique frames.

Two directions (ansatz calibration via linear response; direct construction via drift decomposition) sharing a common primitive: the stationary score. +- **Empirical scaling claim** — DSM+GFDT matches finite-difference accuracy at O(1) integrations per iteration vs O(P) for finite-difference. Demonstrated on 12-parameter model (5 iterations to convergence at 12× lower cost) and 5-parameter Lorenz-96 closure. +- **Cyclo-stationary augmentation** — for periodically forced systems (PlaSim SST with annual cycle), augmenting the state with sin/cos harmonics converts a non-stationary problem to a stationary one in extended state space. +- **Drift decomposition F = M·s + ∇·M** — any drift satisfying the stationary FP equation can be written as score-driven relaxation plus a free mobility tensor. Symmetric part controls fluctuations; antisymmetric part enables circulation without changing the measure. +- **Rolling-caption dedup** — yt-dlp auto-subs produce cumulative text where each new event extends the previous. LCS-based dedup algorithm added to `clean_transcript.py`. + +## Next Steps + +8 child tracks remaining: +- platonic_intelligence_kumar (B #1 — now unblocked) +- free_lunches_levin (B #2 — now unblocked) +- generic_systems_fields (C #1 — needs B done) +- brain_counterintuitive (C #2 — needs B done) +- neural_dynamics_miller (C #3 — needs B done) +- multiscale_hoffman (C #4 — 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. + +## Forward Connections Identified + +This talk informs: +- **cs336_architectures_20260621**: DSM as training objective for diffusion LMs (same Vincent 2011 loss, different architecture). +- **creikey_dl_cv_20260621**: DSM as training objective for image diffusion (DDPM). +- **platonic_intelligence_kumar_20260621**: Speculative cross-modal score — the score function as a representation of the underlying data distribution suggests modality convergence at sufficient scale. + +## Backward Connections + +This talk builds on: +- **cs229_building_llms_20260621**: Same DSM mathematics in EBM context. +- **probability_logic_20260621**: Kolmogorov extension underpins SDE framework; Fokker-Planck is derived from the SDE. +- **entropy_epiplexity_20260621**: Score is gradient of pointwise Shannon information; DSM fits a neural network to this gradient field.
