Honest metric surface (repo bde7adf)

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 sam2_tracker.py (A/B cleared it of the frame-0 seed failure)

A/B TEST: revert sam2_tracker.py to pre-today (isolating fp16 detection change)

Speed pass + honesty docs: sam2_tracker.py
