Content-pipeline Increment 2, part 2 (the tooling). Implements design §11.5
(docs/superpowers/specs/2026-06-24-content-pipeline-design.md):
- tools/pipeline/track.py — the stage-5 geometry pass. Classical path: a
hand-seeded normalized box propagated by OpenCV Lucas-Kanade optical flow
(CSRT used instead when a contrib build provides it), sampled to a SPARSE
loop-normalized keyframed track + an appear/disappear window. Optional ML
detect+track path lazy-imports ultralytics (clear ImportError if absent;
base install needs only cv2). Pure helpers (normalize/denormalize, loop_t,
infer_window, sample_track, track_to_annotation) are unit-tested; the cv2
propagation is an opt-in integration test on real abyss_wow footage.
Semantics are never produced here — geometry only.
- Author mode — /author.html + author.js/.css reuse the preview stage: pick a
pool clip, scrub, drag a seed box, Run tracker (or Add as static box), author
the LEFT detail tiers (general -> scientific+fact) + salience, shift-click to
place affect anchors with RIGHT emotion tiers, and Save to manifest. Backend:
POST /api/author/track (runs track_seed on the clip's base) + POST
/api/author/clip (idempotent upsert via tools.pipeline.manifest — keeps media
+ provenance, replaces only authored content, reloads in place). The tracker
propagates box geometry; all strings/scientific names/facts are hand-typed.
- Repointed the pipeline integration test off the retired forest base to the
cosmos pool primary. USER_GUIDE simulator section brought current (pools,
coast, 3-knob Mood, real-time dream, progressive tiers, author mode).
267 passed / 2 skipped (+ track pure + opt-in real-footage + author endpoint
tests). Author UI by-eye review deferred to the operator (no Chrome on this box).
