v0.6.2

0.6.2 — 2026-07-25

• History scan can recover missed events (python -m app.backfill --rescue). When the
  detect snapshot holds no usable face, the event clip is scanned instead — measured over
  180 events, about one in five yields a face that the normal scan misses entirely.
• Quality gate calibrated against real data, not intuition. A first run put 308 faces
  into the review queue, most of them useless: back-of-head shots, motion blur, and
  outright false positives (a church spire scored 0.57). Sorting 74 finds by detection
  score showed a clean split — below ~0.8 it is mostly junk, above it mostly real faces.
  Rescue therefore requires 0.85 by default (--rescue-min-det), which cuts the yield
  to roughly a seventh and leaves the usable finds.
• Deliberately no filter on gallery match score: a stranger's face scores low by
  definition, and enrolling strangers is what the queue is for. Also no pose filter —
  measurement showed working galleries are full of profile shots (median frontality 0.55),
  so filtering those would discard good references.
