PSA (Peugeot/Citroën/DS) VIN decode was systemically broken: the catalog
vin-group page returns all families unfiltered, so decode fell back to the first
family/salesType (a manual base variant) — yielding "{Brand} {VIN}" model names,
empty transmission, wrong model year, and manual-only parts trees (automatic
gearbox parts missing). Reported for a 1999 Peugeot 106 automatic shown as a 2029
manual with no automatic parts.
- New self-contained PL24PsaService: consumes PL24's FI flow (vin.action →
hintstoken → FI page → json-vin-main-groups → json-vin-illustrations →
vin-image-board). Reads model/year/transmission from the FI identification
table; builds the VIN-indexed parts tree (correct per actual VIN). Does not
touch Ford/Volvo/Nissan/Opel/Hyundai-Kia/Fiat.
- Orchestrator + categories.service route PSA VIN decode/drill to the new service.
- Cycle-correct extractModelYear in @sase/shared (X→1999, not 2029): resolve the
30-yr VIN year code to the most-recent plausible year (≤ now+1); dedupe 6 copies.
Validated live against 13 already-decoded PSA VINs: 12/13 full trees with real
model/year/transmission; automatics correctly detected (106 BVA, 206 AL4, 3008 BVA8).
