Rail Movement Intelligence — MVP

EXPERIMENTAL · ADVISORY · non-identifying · NOT a validated safety system

Anonymous passenger-movement analytics: counting, platform-edge zone occupancy, line-crossing and short-lived anonymous tracks — one detector interface (motion · HOG · YOLO).

YOLO (AI-native detector): ENABLED — demonstrable · built into image. Gate-by-flag — flip ADVANCED_DETECTORS_ENABLED to demo, roll back instantly. Licence/productisation deferred to G-005.

CCTV path: GATED — requires G-003 sign-off (Daniel May). CCTV uploads are quarantined (not processed), blurred-by-default and raw-deleted-after-metrics when enabled.

Boundaries: no biometric, no identity tracking, no operational/enforcement use. Outputs are observation/metric/proxy — never a validated safety alert. CCTV stays gated until G-003. For Rail Safety Advisor (Brandt Clifford) & Privacy/Data Governance (Daniel May) review.
