The spine of the redesign. Presence is now the extent of a track an actor owns, [first_seen, last_seen], rather than the subset of frames in which recognition happened to succeed. An actor recognised only at the end of a long track is present for all of it, which is what the scene-scoped ground truth actually records. AR-013 — `last_seen` as an optional carries the entire liveness state: unset means on screen, set means went off at that timestamp and still revivable, reaped means emitted and erased. No missing-frame counter, no expired flag. It subsumes the tracker's existing two-pool split, so there is no separate revival path — matching a dormant track is ordinary inter-frame association. The asymmetry is the point: interior gaps are claimed, the trailing cool-down is not. A face lost and re-associated within the timeout never closed its track, so the gap is presence — someone briefly occluded has not left the scene. But a track that dies ends at its last sighting, never at the death time. That is precisely the over-claim the retired extinction_sec keep-alive produced, where presence ran on into the closing credits. AR-014 — a belief swap A→B closes the track and opens a successor at the swap frame. Not a correction: two non-twins both clearing the threshold on one face is not realistic, whereas a track_id carried across a viewpoint change onto a different person is. Treating it as a swap-and-continue would emit one window blending two people; treating it as a boundary yields two that are each right. AR-015 — two live tracks owned by one actor means at least one is wrong, since a person cannot be in two places at once. A reverse index catches it on the update that causes it rather than by scanning. This makes identity a third cut detector, independent of the histogram and TransNetV2 and firing where those failed. AR-016 — flush() closes tracks still live at EOF. Without it a film ending mid-shot silently drops its closing cast, which presents as a recognition miss rather than a bookkeeping bug. Reaping hands the dead track to the aggregator and erases it, so the registry holds only live tracks and its size is bounded by concurrent on-screen faces rather than growing with the film. Locking: a frame's association pass is atomic as a unit via FrameScope, since per-call locking would let another thread observe a half-updated frame. owner() reads tally and verdict under one lock — separately, a track could be both unowned and owned within a single promotion decision. A vote for an already-reaped track is dropped and counted, because a nonzero count means the timeout is shorter than the matcher's lag. 11 unit tests, driven directly against the registry with no network and no fixture — the awkward cases are constructed rather than hunted for. Suite: 75 cases, 3236 assertions. Coverage 14/63 to 20/63. Not yet wired into FaceTrackerFunc; that is AR-007/AR-008.
