Backfill + reactive prefetch can re-drill the same category multiple times, and the parts insert path had no dedupe guard. Result: 8.2% duplicate rows on pl24, 14.5% on parts-catalogs, and 33.7% on emex — ~108k extra rows across 7,571 categories on 224 vehicles. Every drilled catalog page rendered each part twice (the Tampon example: 32 rows for 19 distinct OEMs). * Migration 0010 — phase 1 deletes existing dupes preserving the oldest row per (vehicle_id, category_id, oem_code, name, position) group; phase 2 adds a UNIQUE INDEX over the same tuple with NULLS NOT DISTINCT (PG 15+) so null position/vehicle_id collapse like equal values rather than each counting as its own "distinct" row. Idempotent CREATE UNIQUE INDEX IF NOT EXISTS so the runner is safe to re-apply. * All five insert(parts).values(...).returning() call sites (parts.service, categories.service ×3, catalog.service) get .onConflictDoNothing() so future re-drills no-op instead of erroring on the new constraint. `.returning()` continues to surface only the newly-inserted rows; existing logs read `Stored N parts` as actual net insertions, which is what we want. Dry-run on dev DB: 524,540 → 425,186 parts (99,354 dupes deleted), index created cleanly. Same delta expected on prod (~108k drop). drizzle-orm 0.41 doesn't expose .nullsNotDistinct() on the index builder so the constraint is owned by raw SQL — see the inline comment in the parts schema and the migration file. Future schema generators should NOT try to drop or rewrite this index.

Katalog Mimarisi
- PL24 P5 Modern (REST/JSON) — VW Group, BMW, Mercedes, Renault, Toyota...
- PL24 P4 Legacy (HTML scrape) — Ford, PSA, Hyundai/Kia, Nissan, Opel, Volvo
- PartsCatalogs (REST + Playwright JWT) — geniş VIN kapsamı
- EMEX (Playwright scrape,

EMEX & PartsCatalogs Türkçeleştirme
EMEX ve PartsCatalogs kaynakları kategori/parça isimlerini İngilizce (zaman zaman Rusça) döner. Çeviri akışı:
TranslationsService(apps/api/src/translations/) — Redis cache → DB lookup (emex_category_translations) → orijinal döndür. Dictionary tabanlı word-by-word replace devre dışı (yarı-İngilizce çıktı yaratıyordu).- Hot path (
categories.service.ts) — EMEX/PCAT insert noktalarındatranslateMany()ile bulk lookup yapılır; cache miss varsa orijinal yazılır, sonraki bootstrap pass'inde LLM ile çevrilir. - Bootstrap script (
scripts/emex-translate-bootstrap.ts) — DB'deki tüm uniquename_originaldeğerlerini OpenRouter üzerinden DeepSeek V3 ile çevirir,emex_category_translationstablosuna yazar. - Backfill script (
scripts/emex-backfill-tr-names.ts) — translation tablosuna göre mevcutcategories.nameveparts.namedeğerlerini günceller, Redis cache flush eder.
# 1) Tüm yeni terimleri çevir (~$0.50, ~30 dk)

# 2) DB kayıtlarını güncelle
pnpm exec tsx scripts/emex-backfill-tr-names.ts --dry-run
pnpm exec tsx scripts/emex-backfill-tr-names.ts
# 3) API restart (yeni hot-path translateMany için)
