The chained attempt (1530bbc) fed each run's result into the next frame's
seed, so a wrong read on one frame carried into the ones after it. Runs are
independent again: every frame is seeded from the drawn shape, frames 2-5
with it grown x1.5 about its centre for motion tolerance. REQ-189, ui-spec
and tasks.md updated to the independent contract.
trackForward sent the identical box to all five target frames. On batch 19
(extracted at 0.5 fps - one frame every 2 s) a truck entering the frame
outruns a static seed, so the action either missed it or grabbed the wrong
part.
- geometry handling lifted to module-level shapeBox(), reused for the drawn
shape and for each assist result
- first frame still uses the drawn box exactly; frames 2-5 are seeded with
the previous run's shape grown x1.5 about its centre (SEED_GROWTH)
- a frame SAM3 refuses keeps the last good seed for the next attempt
- REQ-189 rewritten to the chaining contract, including the accepted cost:
a bad read can carry forward; this is not tracking, no motion model
trackForward read geometry.coordinates, a key the backend never emits, and
had no bbox branch - the action silently no-op'd for every shape (flagged
dead in docs/audit-2026-08-07.md:103).
- bbox points used as-is, polygon reduced to its bounding box
- guards speak instead of returning silently
- a frame SAM3 refuses no longer aborts the remaining frames
- a press during an in-flight run is ignored (would double-write)
- REQ-189 added; non-goal requirements.md:22 amended to keep exemplar
propagation out while admitting this one-shot hand-off
- REQ-181: class_params {name: {threshold?, iou_threshold?, min_box_frac?}}
on /preview and /autolabel, per-class override table in both modals;
empty overrides take the unchanged global path
- REQ-180: x button on each review sidebar class row clears that class on
the current frame only via bulk-delete, no confirmation
- includes REQ-178 empty date-folder cycle fix (archive_index.py)
This commit includes major additions and updates to the frontend and backend architectures, introducing new dataset management, live counting features, batch processing, and triage logic. Includes new UI pages, components, and API routes.
