PersonAnalysis now carries the policy Evidence; view_model builds a Qt-free per-person diagnostic line (acc/horiz/ang/rapid/cand/state, or the reject reason) and VideoView overlays it in a corner. Read-only, no decision change; locates where a real fall stops. 67 tests pass. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
