## Launch prompt

> The audio isn't playing at all. Let's fix that and then let's make sure there are
> left and right brain tracking labels for everything. Make sure you're working on a
> worktree. There are other concurrent sessions that may have real merge conflicts to
> handle.

## Pre-state

- The simulator (`simulator/`) is a FastAPI + static-JS experience: an altitude dial
  over 6 scales (cosmos/orbit/sky/coast/reef/abyss), 41 rotating-pool clips, a
  real-time Kuwahara "dream" shader, two HUD label layers — **Think** (left-brain
  factual chips, `#overlay`) and **Feel** (right-brain affect words, `#affect`) —
  plus a per-altitude soundtrack with a 0–10 audio dial and a built-in
  `#audio-status` diagnostic.
- s0027 had brought all 41 clips to left+right annotation with 4-lang parity, but the
  left labels were thin (many clips 1–2) and STATIC; affect was authored PER-SCALE
  (every clip in an altitude shared 4 feelings).
- Operator was running a stale `:8000` server on the `design/cloudflare-static-publish`
  branch (a concurrent session's WIP — "Run simulation" begin-experience flow, +
  later a credits page). Project is EXEMPT from the Wiggleverse deploy pipeline
  (flotilla/PPE/§9); public target is static Cloudflare. cv2/imageio NOT installed in
  this env.

## Session arc

1. **Worktree.** Created native worktree `fix+audio-and-tracking-labels` off
   `origin/main` (582183d). All work done here.
2. **Audio (systematic-debugging) — FALSE ALARM.** Could not reproduce "no audio" in
   ANY automated condition: Chromium + WebKit, strict autoplay
   (`--autoplay-policy=user-gesture-required`), clean-main server AND the operator's
   `:8000` WIP server, via Video-toggle / Audio-dial / "Run simulation" button; all 5
   soundtracks decode to real non-silent audio (RMS 0.08–0.24). The raw
   native-controls `#aud-test` player was ALSO silent on the operator's Safari while
   the element reported playing → isolated it BELOW the app. Operator confirmed:
   **their Safari sound was muted.** No code change.
3. **"Labels not showing" on cosmos_tarantula.** Root cause: operator was on `:8000`
   (design branch), whose manifest had that clip's `annotations: []`. My branch
   renders all labels correctly; labels are knob-gated (none at Think/Feel 0).
4. **Left (Think) enrichment.** Every clip → ≥3 factual labels (added one to each of
   23 thin clips; orbit_bluemarble 1→3), full es/fr/ja parity. Pipeline:
   `LABELS` in `build_pool_manifest.py` → build → catalogs → `translate_manifest.py
   merge`. (commit `8cfceff`)
5. **Motion-tracking.** Converted the 4 still-static abyss creatures (octopus, bigfin
   squid, dandelion siphonophore, sea pig) static→tracked, 3-keyframe paths sampled
   by eye from frames (cv2 unavailable). Tracked clips 7→11. (`8cfceff`)
6. **Think/Feel overlap avoidance.** `renderAffect` now nudges Feel words off Think
   chip plates (obstacles computed from manifest, tracked paths sampled → holds whole
   loop, no per-frame jitter; new `window.__hefNoDeconflict` seam). Verified 0
   overlaps across all 6 scales incl. a tracked clip over time. (commit `041fcde`)
7. **Per-clip right-brain feelings.** Operator: feelings should match each ACTUAL
   video. Added `AFFECT_CLIP` (per-clip override, scale fallback) for all 41 clips →
   41 distinct feeling-sets. cosmos done by me as a reviewed sample; the other 5
   scales drafted by **5 parallel subagents** (one per scale) that each VIEWED footage
   frames and followed the cosmos recipe; I normalized + authored all es/fr/ja for the
   19 new nuance keys. 42 distinct feeling keys now. (commits `bf1013b` + `2d54023`)
8. **Merge.** Merged branch → `origin/main` (clean; main had only advanced by
   `sessions/` transcript commits). Confirmed all 4 work commits are ancestors of
   `origin/main`; another session (`feat/accessibility-pass`) has since merged main +
   a11y on top (`380c2d1`).

## Cut state (final)

- All work committed, merged to `origin/main`, pushed. Working tree clean.
- Verification: 34/34 catalog+i18n+build pytest, 16/16 node unit, live render shows
  ≥3 Think chips + distinct Feel words per clip (incl. new keys) with overlap 0 and no
  JS errors. (3 unrelated pytest failures = cv2/ffmpeg absent in this env.)
- Worktree RETAINED (not torn down) because it is serving the operator's by-eye review
  at `http://127.0.0.1:8011/author.html`; tear down + stop `:8011` when review done.
- §9 deploy pipeline: N/A — project is exempt (static Cloudflare target).

## Deferred decisions (low-confidence calls)

- **Audio = no code change.** Chose to treat it as environmental after exhaustive
  repro rather than guess-patch a working engine; operator confirmed muted Safari.
- **Left-label box positions authored WITHOUT viewing each frame** (23 enriched
  clips, except bluemarble) — factual text is grounded, positions are estimates that
  want by-eye review.
- **Per-clip feelings drafted from a single MID-FRAME** (motion not seen) via parallel
  subagents — first-pass reads; emotions may want tuning once a clip is in motion.
- **Left reef/coast moving-subject clips left STATIC** (reef_redsea/flowergarden
  schools, coast_otters/seals) — tracking deferred (diffuse subjects + cv2 absent).
- **Merged directly to `main` via `git push HEAD:main`** (no Gitea PR) at operator's
  explicit request; gh is GitHub-only here and no `tea` CLI.

## Operator plate

- Review the first-pass label/track/feeling positions in `/author.html` on `:8011`.
- For Think: check each chip sits on its subject + the 4 abyss tracks follow the
  creature. For Feel: check emotions ring true once clips are in motion.

## Next /goal

```
/goal refine the first-pass left-label box positions and the 4 abyss creature tracks per operator by-eye review (grab a frame per clip, nudge each chip onto its subject), and motion-track the remaining moving-subject clips (reef schools, coast animals) — data-only via build_pool_manifest + i18n pipeline
```
