The module doc still mandated landscape (2026-06-30 ARKit constraint);
portrait was validated live 2026-07-02 and is now the concert default.
Document the rotation split (video ccw, 2D points already upright).
Three perf optimizations stacked on top of the distributed pipeline:
1. multihmr_server.py ported to pyobjc CoreML.framework direct
(drops the ~30 ms coremltools.MLModel.predict overhead). Compiles
the mlpackage to .mlmodelc on load, then predicts via
MLDictionaryFeatureProvider + MLMultiArray ctypes memcpy. Toggle
MULTIHMR_SERVER_BACKEND=coremltools for fallback. setup script
installs pyobjc-framework-CoreML on the macm1 venv.
2. MediaPipe Holistic now uses GPU Metal delegate on M5. Required
wrapping camera frames as SRGBA (4-channel) instead of SRGB --
the Metal CVPixelBuffer path rejects 3-channel formats. Bench
M5 standalone : pose 6.7 -> 2.9 ms, face 4.0 -> 1.0 ms, hand
6.1 -> 3.2 ms. Frees ~10 ms CPU per frame for OSC + rigger.
3. Remote client queues bumped maxsize 1 -> 2/3 (in/out) to absorb
jitter without stalling capture.
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.
