Bite-sized TDD plan for Increment 1 (real footage, no ML): the deterministic
tools/pipeline/ package (frame → crossfade-loop → master+proxy transcode →
manifest assembly, pure ffmpeg arg builders unit-tested + an opt-in integration
test on the real forest POC base), the backward-compatible keyframed annotation
track schema with client-side interpolation, and the 5-scale ring (orbit + reef).
9 tasks. Implements spec §3 (stages 1–4,6), §4, §5, §6, §7, and §8 Increment 1.

Add scale-ring navigation to the simulator per the scales-library design §3:
an endless rotary-encoder control (relative, vs the absolute 0-4 experience
knobs) walks a closed ring of neutral "scales of nature" clips, with placeholder
AI zoom/warp transitions between adjacent scales and a small->large wrap (the
infinite-zoom payoff).
- player/ring.py (new, canonical pure logic): ScaleRing + advance_ring; one
transition clip per edge, played forward zooming inward / reversed outward;
modulo wrap both ways; chained steps for a multi-detent spin. Mirrors
player/content.py conventions (frozen dataclasses, pure functions).
- simulator: load_ring + ring_to_dict/ring_move_to_dict; GET /api/ring and
POST /api/ring/advance (Python owns step/wrap/transition math; the browser
only plays the returned transition(s) then settles on the target scale).
- frontend: endless-encoder control (zoom in/out buttons + stage scroll),
current-scale readout, multi-clip active-scale selection, transition playback.
- media: two cheap true-PD scales so the ring is demonstrable -- cosmos
(NASA/Hubble) + abyss (NOAA Ocean Exploration), provenance recorded in the
manifest, bytes generated as labelled placeholders by setup_scales_media.py.
The expensive multi-strength flow-stabilized Right re-bake is DEFERRED (new
scales carry a raw base only) until the ring is liked; Pi renderer +
serial/firmware remain deferred (simulator-first).
- docs: ROADMAP slice-3 done; USER_GUIDE scale-ring gesture; plan doc.
Verified: pytest 215 passed / 2 skipped (+22 new); sim boots, /api/ring +
/api/ring/advance correct incl. wrap, media served, and a headless-Chrome CDP
drive walked cosmos -> forest -> abyss -> (wrap) -> cosmos with the active clip
reloading correctly.
