## Plan

Implement the scales-library design §3 (scale navigation & zoom transitions) in
the simulator. The "what" was already approved in session 0008's design, so no
fresh brainstorm: keep the navigation math **Python-canonical** in a new pure
`player/ring.py` (mirrors `player/content.py`/`alteration.py`), expose it via the
simulator API, and have the browser only *render* (play returned transition(s),
settle on the target scale, keep the live knob alteration on top). Add two cheap
**true-PD** scales (cosmos, abyss) so the ring has ≥2 demonstrable scales;
**defer** the expensive multi-strength flow-stabilized Right re-bake (new scales
carry a raw base only) and keep deferring the Pi renderer + serial/firmware per
[[simulator-first-before-hardware]]. Process: short plan doc → TDD pure logic →
API → media → UI → verify (boot + headless drive) → branch → PR → merge.

## Launch prompt

```
/goal Build scale-ring navigation in the simulator — add an endless rotary-encoder
control (relative, vs the absolute 0-4 experience knobs) that walks a closed ring
of neutral "scales of nature" clips with placeholder AI zoom/warp transitions
between scales. Add 1–2 cheap, true-PD neutral base clips so the ring is
demonstrable (NASA/Hubble cosmos + NOAA Ocean Exploration deep sea). Defer the
expensive real multi-strength flow-stabilized Right re-bake until the ring is
liked; keep deferring the Pi renderer + serial/firmware.
```

## Pre-session state

- `main` @ `7cf550a` locally, clean; behind `origin/main` by 1 after the claim
  (sessions live in this same repo under `sessions/`); fast-forwarded during init.
- Slice 1 (player core, PR #5) + slice 2 (sim alteration, PR #7) + calibration
  lock & dark-grade fix (PR #8) all merged. `DEFAULT_CALIBRATION` locked unity/linear.
- Simulator had ONE neutral clip (forest) wired with the real flow-stabilized
  Right variant; no ring, no second scale.
- Ran from the **main clone** (not a nested worktree) — the 0010 resolver gotcha
  did **not** recur.

## Turn-by-turn arc

1. **Gate / classify + claim.** `/goal …` → unambiguously a coding session. Ran
   `wgl-session-coding-init`; dry-run peek showed no in-flight sessions; claimed
   session **0011** (type coding) at `6cf1ae0`. Verified clean pushed `main`
   baseline + the `@~/.claude/wiggleverse.md` stub.
2. **Read context.** `[[sub-project-3-player-progress]]` memory + the scales
   design (`2026-06-07-scales-library-and-right-axis-pipeline-design.md` §3 ring /
   §2 scales / §2.1 strict-PD map). Surveyed `simulator/` (`clips.py`, `app.py`,
   `setup_sample_media.py`, static), `player/` (content/controls/alteration/state),
   and the `test_clips.py` / `test_simulator_api.py` contracts.
3. **Plan.** Wrote `docs/superpowers/plans/2026-06-07-scale-ring-navigation.md`
   (6 tasks). Key design choices: ordering index 0 = largest (cosmos), +1 zooms
   inward, both wrap; **one transition clip per edge**, forward inward / reversed
   outward (N transitions for N scales); ring math is canonical Python, the browser
   only renders; new scales carry a raw base only (Right re-bake deferred).
4. **TDD Task 1 — `player/ring.py`.** Red `tests/test_player_ring.py` (12 cases:
   construction/validation, `scale_at` mod, single-step in/out, wrap both ways,
   multi-detent chaining, full-loop, no-op, degenerate N≤1) → implemented
   `Scale`/`Transition`/`ScaleRing`/`TransitionStep`/`RingMove`/`scale_at`/
   `advance_ring` → green.
5. **TDD Task 2 — data layer.** Extended `tests/test_clips.py` → added
   `load_ring` + `ring_to_dict` (scales carry their clip title) +
   `ring_move_to_dict` (`target_clip_id`) to `simulator/clips.py` → green.
6. **TDD Task 3 — API.** Extended `tests/test_simulator_api.py` → added
   `GET /api/ring` (404 if no ring) + `POST /api/ring/advance` to `simulator/app.py`
   (loads the ring into `app.state.ring`) → green.
7. **Task 4 — media + manifest.** Rewrote the committed
   `simulator/sample_media/manifest.json`: added `cosmos` (NASA/Hubble) + `abyss`
   (NOAA Ocean Exploration) clips with true-PD provenance (17 U.S.C. §105 / NOAA),
   empty `right_variants` (deferral), illustrative annotations, and the `ring`
   section. Broadened `.gitignore` to `simulator/sample_media/**/*.mp4`. Wrote
   `simulator/setup_scales_media.py` — synthetic labelled placeholder bases +
   per-edge `xfade=zoomin` transitions. First run failed (xfade `-22`: forest base
   is 1920×1080@29.97 vs synthetic 1280×720@25) → fixed by normalizing both inputs
   (scale/fps/sar/format/trim) before xfade. Re-ran clean: 3 bases + 3 transitions.
8. **Task 5 — frontend.** Rewrote `app.js` for multi-clip active-scale selection
   by ring index, an endless-encoder control (⊖ out / in ⊕ buttons + stage
   mouse-wheel), current-scale readout, and sequential transition playback that
   restores the live alteration on settle; added the control to `index.html` + CSS.
9. **Verify.** Full suite **215 passed / 2 skipped** (+22 new). Booted the sim on
   :8011; `/api/ring`, `/api/ring/advance` (incl. the abyss→cosmos wrap), and
   `/media` all correct; headless-Chrome initial screenshot showed the cosmos
   placeholder + the ring control. Then a **CDP drive** (websockets) called
   `advance(1)` ×3, walking cosmos → forest → abyss → (wrap) → cosmos with the
   active video reloading `cosmos/base.mp4`; post-nav screenshot confirmed.
10. **Docs.** ROADMAP slice-3 = done (+ folded the ring-transitions into the
    offline-pipeline bullet); USER_GUIDE gained the two-step media setup + the
    scale-ring gesture.
11. **Ship.** Committed; pushed `feature/scale-ring-navigation`; created **PR #9**
    and merged it via the Gitea API helper (`gitea-api.sh git.benstull.org`, merge
    commit `435f201`, branch auto-deleted); synced `main`; deleted the local
    branch. Post-merge suite green. Updated memory + finalized.

## Cut state

- `main` @ `435f201` (PR #9 merged). New `player/ring.py` + `tests/test_player_ring.py`;
  `simulator/clips.py`/`app.py`/`static/*` extended; `simulator/setup_scales_media.py`
  + manifest cosmos/abyss/ring; ROADMAP + USER_GUIDE updated. Full suite 215 passed /
  2 skipped. Working tree clean; local + remote feature branch deleted.
- Sub-project 3 = **⏳ in progress**. Slices 1–3 done; remaining slices (runtime
  renderer, serial framing, white-noise, **offline v2v pipeline now incl. real ring
  transitions**, catalog model) in ROADMAP §3 + [[sub-project-3-player-progress]].
- Scale-ring media is placeholder (gitignored); repopulate with
  `python simulator/setup_sample_media.py && python simulator/setup_scales_media.py`.

## Deferred decisions (operator plate)

Low-confidence / judgment calls made autonomously this session:

1. **Ring shape = cosmos → forest → abyss (3 scales).** The goal asked for 1–2 new
   true-PD clips; added two (cosmos, abyss) to the existing forest for a 3-scale
   ring — the minimum that exercises both an interior edge and the wrap seam.
   Forest sits between them as a stand-in for the terrestrial/mid scales (the
   design's PD soft spot, §2.1); real ordering (orbit/forest/reef/abyss/micro/cosmos)
   is an artistic call for when real footage is ingested.
2. **One transition clip per edge, reversed for the outward direction.** Halves the
   bake count (N not 2N) and matches the design's "one clip per ring edge." The
   browser plays the placeholder forward in both directions for now (true reverse
   playback is a renderer concern); the `reversed` flag is carried through the API
   so the real pipeline / Pi can honor it.
3. **"True-PD" = provenance recorded, bytes are labelled placeholders.** Media is
   gitignored, look-tuning-only, and real ingest is sub-project-2 territory (an
   open question in the design). The manifest records the real NASA/NOAA PD
   sources + license; `setup_scales_media.py` generates cheap synthetic stand-ins
   so the ring is always demonstrable offline. A `--fetch` real-download path was
   noted as a future bonus but not built (network-fragile; deterministic offline
   verification preferred).
4. **Right axis on the new scales is a no-op (deferral).** New scales have empty
   `right_variants`; the `Clip` model already falls back any unauthored strength to
   the raw base, so this is a clean structural expression of "defer the expensive
   re-bake until the ring is liked."

## Next-session prompt

Tune the ring by eye and decide whether the experience is "liked"; once it is, the
big next build is the offline v2v pipeline (real Right re-bake **and** real ring
transitions) + strict-PD ingest. Read [[sub-project-3-player-progress]] and the
scales design §3/§4 first.

```
/goal Tune the scale-ring experience in the simulator by eye — transition feel/length,
scale ordering, the wrap moment, fast-spin behavior — and decide whether it's "liked."
If liked, begin the offline v2v variant pipeline: the real multi-strength
flow-stabilized Right re-bake per base clip PLUS real first-last-frame-i2v /
infinite-zoom ring transitions to replace the placeholders, and source/ingest the
actual strict-PD scale clips (NASA/NOAA/NPS) via sub-project 2. Keep deferring the
Pi renderer + serial/firmware. Per docs/ROADMAP.md §3 and the scales design §3/§4.
```

Note: PRs on this repo go through the **Gitea API** (`wgl-gitea-admin`
`gitea-api.sh`, host `git.benstull.org`) — no `tea`/`gh` installed. Running from
the main clone (not a nested worktree) avoided the 0010 resolver-ambiguity gotcha.
