display:none only — element IDs, JS handlers and endpoints stay intact,
so re-enabling is dropping three inline styles. Default batch mode is
manual for the POC, so operators shouldn't see DO/OCR controls.
- canonical_plate (uppercase alnum, strips space/dot/hyphen) at all plate
write sites; pretty_plate for render (history, XLSX, operator tile) so
B 1234 XYZ and B1234XYZ are one plate everywhere
- group_dos_by_plate compares canonical plates -> no false mixed_plates
- warn-only (never blocking) plate format hint in operator + monitoring modals
- batch.default_mode: manual (auto merged truck loads when a sack sat in the
counting ROI); operator banner explains plate -> start -> stop
- docs + AGENTS known-limitation note; 85 tests pass
Big docked truck bbox rests 1-2px past detection_polygon bottom edge, so
100%-containment made truck_in_area flicker False -> batch 15 split (6+276)
on 2026-09-29 while the truck never left. v4-best.engine detected it at
conf 0.92-0.97 in every replayed frame (no model miss, no retraining).
- truck gate: frac_inside >= 0.5 instead of contains(bbox)
- batch.truck_gone_tolerance_seconds (new, 30) authoritative; drop the
hardcoded batch_mgr._truck_gone_tolerance = 30.0 override;
batch.timeout_seconds documented as sack-idle pause only
