"""hoa64 — spatial calculator: 7th-order Ambisonics (Ambix ACN / SN3D).

Fixed spherical-harmonic geometry (Farina / Ambix), not a learned model.
State dimension is exactly 64 = (7+1)**2.

Phases:
  0 — basis, encode/decode, rotate, intensity DOA, RNN pose stub
  1 — WAV I/O, HOA streams, STFT bands, JSON spatial reports for other AIs
  2 — Fast Wigner-D HOA rotation (default)
  3 — Vision boxes/rays on sphere + A/V fuse + Qwythos API
