feat: progressive_drift_fraction as a per-request InsightsOptions knob - #68
Merged
Conversation
…ons knob The walk-vs-dwell sensitivity (ADR 0014) was a module constant (_PROGRESSIVE_DRIFT_FRACTION=0.5). Expose it as InsightsOptions. progressive_drift_fraction (default 0.5, gt=0 le=10) and thread it through detect_stops -> _is_progressive_translation. A cluster is movement when its half-to-half centroid drift exceeds fraction*stop_radius_m; lower rejects more aggressively, a large value effectively disables the filter. Backward-compatible (same default); direct detect_stops callers keep the module-constant default. Verified: default (0.5) rejects a slow walk (0 stops); 10.0 keeps its chunks (2 stops); dwell still 1 stop; out-of-range values are a clean 422.

Exposes the walk-vs-dwell sensitivity (ADR 0014) as
InsightsOptions.progressive_drift_fraction(default 0.5,gt=0 le=10), threaded throughdetect_stops→_is_progressive_translation. Lower rejects movement more aggressively; a large value effectively disables the filter. Backward-compatible (same default). Verified: default rejects a slow walk (0 stops), 10.0 keeps its chunks (2), dwell still 1, out-of-range → 422. Adversary suite 63 passed.
