Head movement: refuse implausible values (repo main)

Head movement: shared per-frame ruler, max of both fighters (repo main)

Head movement: per-frame scale + robust spread (repo 8579db9)

Honest metric surface (repo bde7adf)

Left/right rule says what it does (repo 639459d)

Tracker seam + output contract (repo 414cb28)

Fix speed-pass regressions: lazy model imports (NameError silently killed SAM2), pin imgsz/conf on shared cached model, torso-weighted seed ranking, MAX_PUNCH_CALLS 10, log-only seed diagnostics

Restore optimized pose_features.py (A/B cleared it of the frame-0 seed failure)

A/B TEST: revert pose_features.py to pre-today (isolating fp16 detection change)

Speed pass + honesty docs: pose_features.py
