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.

Tuning the look by eye in the simulator (design §8) surfaced that the dark
mood pole rendered a full-frame hue-rotate(-200deg) — rock orange, trees
purple: the disorienting look rejected in session 0008, not the peaceful POC
dark_frame. Replace it with darken + slight desaturate on the video filter
plus a multiply-blended deep-blue wash (#tint, below the SVG HUD so the
overlay stays legible). Dark now reads cool/somber with natural greens, like
the approved POC look; light/left/right unchanged and confirmed peaceful.
With full tilt now tasteful on every axis, LOCK DEFAULT_CALIBRATION to unity
gains + linear variant map as a deliberate by-eye choice (not placeholders),
closing the open session-0006 knob->strength decision: knobs run 0=off..4=max,
equal Dark/Light = identity, the 5 notches map 1:1 to the 5 discrete Right
bakes. Guard the locked constants with test_default_calibration_is_locked.
Resolves design §8 open questions (calibration curve shape; grade-vs-overlay
ordering) and records the dark-grade fix. Full suite 193 passed / 2 skipped.
