# MotionCapture

This workstream provides a watch-only `CMMotionManager` adapter and a pure
calibrated classifier. The adapter is foreground/lifecycle-bound: it stops on
inactive scene, relay loss, expiry, cancellation, or sensor failure. Samples
are bounded and in memory only; no recording mode or raw traces are included.

The orientation transform (wrist side and crown orientation) and thresholds are
versioned hypotheses pending physical validation. The package tests prove
state-machine behavior only and are not evidence of reliable watch recognition.

## Evaluation report (pending hardware)

No Apple Watch or TV has been tested for this workstream. Precision, recall,
incidental-movement false triggers, and the direction confusion matrix remain
`pending physical evaluation`; do not infer them from synthetic fixtures.
The required report should include per-direction TP/FP/FN, precision/recall,
duplicate count, false triggers per armed hour, and a 4x4 actual-vs-predicted
matrix split by wrist and crown orientation.

See `INTEGRATION-PROPOSAL.md` for target membership, permission-string, and
lifecycle integration requirements.
