Live session outcomes: (1) pinch thresholds validated for inner
fingers frozen as defaults (ratio_on 0.50, margin 0.05, ext_min 1);
(2) panel frames + X/Y gauges now permanent (no early-return when
nothing is detected); (3) wxcvbn source-bundle shortcuts gated off by
default (VIZ_SOURCE_KEYS=1 re-enables) — a stray key mid-performance
switched the audio scene.
Add hand_facing() palm-spread metric (dist(kp5,kp17)/hand_size).
Gate GestureSlotStabilizer slot activation on facing >= HAND_FACE_MIN
(default 0.5) with 0.8x hysteresis; side-on palms no longer arm
pinch/strike. Add VizConfig.hand_face_min + HAND_FACE_MIN env var.
Update test fixtures: _near_hand() now spreads kp[5]/kp[17] so
existing tests keep passing through both near+face gates.
config.py: PINCH_EXT_MIN docs said "min frames for debounce"
— it is min extended fingers required to fire; fix wording.
HAND_PERSIST_FRAMES said "persist after disappearance" — it
is frames required before a hand is drawn; fix wording.
CLAUDE.md: MEDIAPIPE_DELEGATE default was "cpu" — real
default is "gpu" (config.py); fix the RC0.1+ table row.
Add missing PINCH_ENABLE / VIZ_HUD / CONCERT_MIRROR rows
to the main env-vars table.
Rotate the iPhone/webcam frame before MediaPipe and display
so detection, skeleton overlay and the shown video stay
aligned after the phone is physically rotated. ARKit 3D
world joints are orientation-invariant and untouched.
Wire finger_piano.scd into both data-only boot paths so
OSCdef /pose/finger and ~fp* API are available at runtime.
Call ~fpModTick on every /pose/hands frame (~30 Hz) for
continuous air-piano modulation. Document FINGER_PIANO env
vars in CLAUDE.md.
Root CLAUDE.md (overview, where-to-look, conventions) plus
nested files for data_only_viz, oscope-of, launcher.
sound_algo already had its own nested tree.
Sized for the ~150-instruction budget: root 43 lines,
each nested 43-52 lines, telegraphic style.
