/**
 * Lot Watch Pattern Tests
 *
 * Tests core functionality from DESIGN §15:
 * 1. Capture: appends sighting with normalized plate
 * 2. Classification: ours / offender / guest / unknown
 * 3. markVehicle retro-classifies existing sightings
 * 4. Dedup/grouping: repeat plates group with count 2, blank-plate description fallback
 * 5. Report computeds: spot-occupancy counts; repeat-offender leaderboard ordering
 * 6. Admin gating: curation actions are no-ops without admin credential
 * 7. LLM extraction (Phase 2): NOT unit-tested. `generateObject` is invoked
 *    inline during the pattern body and returns a reactive result/error pair;
 *    the test harness has no boundary seam to intercept the model call, and we
 *    won't hit a live model in tests. Coverage strategy:
 *    - `extractionPending: false` and `extractionError: ""` on saved sightings
 *      are asserted implicitly by the s1/s2 capture cases.
 *    - The end-to-end "photo → extracted plate/description flows into the
 *      editable draft fields → save" path is covered by browser verification
 *      (see PR #3712 description + lot-watch design doc §7). Treat as a
 *      tracked follow-up: add a generateObject seam (e.g. an injectable
 *      extractor input) to enable unit-testing this without a live model.
 *
 * NOTE: Uses .filter(() => true).length for array lengths per reactivity tracking note.
