+
+## Entry Points
+
+- `apps/api/src/main.ts` — API bootstrap (also serves built web via ServeStatic; no nginx in prod)
+- `apps/api/src/worker.ts` — BullMQ worker process (separate container)
+- `apps/api/src/database/migrate.ts` — custom SHA256-tracked migration runner over `apps/api/drizzle/` (14 SQL migrations + `meta/_journal.json`)
+- `apps/web/src/main.tsx` — SPA bootstrap (`routeTree.gen.ts` generated by `tsr generate`)
+
+## API Modules (`apps/api/src/`)
+
+- **vehicles/** — VIN decode orchestration; fallback chain Corgi → PartsCatalogs → PL24 → EMEX → NHTSA; slim decode response + Redis candidate stash (`vin-cache-keys.ts`)
+- **integrations/pl24/** — PartsLink24: shared P4 core + per-brand services (`psa`, `volvo`, `ford`, `hyundai-kia`, `opel`, `ford-legacy`) + `parsers/`
+- **integrations/emex/** — emexdwc.ae scrape: HTTP via undici ProxyAgent, Playwright fallback (`emex.browser.ts`), tree parser
+- **integrations/parts-catalogs/** — PartsCatalogs API ("pcat")
+- **integrations/p/** — OEM cross-reference ("P", TecDoc-derived MySQL db; `P_DB_*` env)
+- **integrations/corgi/**, **vin-api/** — offline WMI lookup; NHTSA fallback
+- **integrations/catalog-source-db/** — upstream source-DB bridge
+- **catalog/** — catalog browse endpoints (`catalog`, `pcat-catalog`, `emex-catalog` controllers/services)
+- **categories/**, **parts/**, **brands/** — category tree (partCount rollup, lazy drill/heal), parts, brand canonicalization
+- **auth/** (better-auth cookie sessions), **users/**, **referrals/**
+- **payments/** (Stripe), **subscriptions/**, **plans/**
+- **jobs/** — BullMQ queues + processors: `catalog-prefetch`, `emex-scrape`, `translation`, `lifecycle-email`, `subscription-expiry`, `query-cleanup`

+- **notifications/** (Novu), **email/** (Postal), **chatwoot/**

+- **config/** — `env.validation.ts` zod gate (beware `""` vs undefined), `configuration.ts`
+- **database/** — Drizzle provider + `schema/` split: `core`, `pl24`, `emex`, `parts-catalogs`, `relations`
+
+## Web (`apps/web/src/`)
+
+- **routes/** — public: `index`, `pricing`, `blog`, `demo`, `about/contact/kvkk/privacy/terms` · `_auth/`: login, register, forgot/reset password, email-verified · `dashboard/`: `search` (main VIN flow), `vehicles_/$id[/categories_/$categoryId]`, catalog trees (`catalog_/$brandName/...`, `catalog_/pcat/...`, `catalog_/emex/...`), `oem.$code` (cross-ref), `subscription`, `billing`, `history`, `settings`, `service-test` (admin), `admin/*` (users, analytics, referrals, copy-logs)
+- **lib/** — `api-client`, `auth-client`, `posthog`, `surveys` (API-mode survey renderer), `meta-pixel`, `faro`, `sentry`, `chatwoot`, `i18n`, `vehicle`
+- **stores/** (zustand), **components/**, **remotion/**, **messages/** (i18n), **hooks/**
+
+## Configuration
+
+- `turbo.json`, `biome.json`, `tsconfig.json` — build/lint/typecheck pipeline
+- `docker-compose.coolify.yml` — prod/staging: `api` + `worker` + `sase-redis` (Coolify env reaches a service ONLY if its `environment:` block references `${VAR}`)
+- `Dockerfile` — multi-stage node:22-alpine + Chromium (runtime imports MUST be in `dependencies`)
+- `ecosystem.config.js` — PM2 config
+
+## Tests
+
+- API: 30 `*.spec.ts` (Vitest) → `pnpm --filter api test`
+- Web: 24 `*.test.ts(x)` (Vitest only; **no Playwright e2e**) → `pnpm --filter web test`; plus per-package `index.spec.ts`
+- `qa/post-deploy/` smoke checks
+
+## Key Dependencies
+
+NestJS 10 · drizzle-orm 0.41 + postgres · better-auth · bullmq + ioredis · stripe · posthog-node · openai (translations) · undici (proxied fetch — global fetch lacks `dispatcher`) · Sentry + OpenTelemetry · mysql2 (P/TecDoc) ·· React 19 · TanStack Router/Query · zustand · posthog-js · @grafana/faro · remotion · zod throughout.
+
+## Quick Start
+
+1. `pnpm install`
+2. `pnpm dev` (turbo: api :4000 + web :3000)
+3. `pnpm lint` / `pnpm typecheck` / `pnpm test`
+4. DB: `pnpm --filter api db:migrate` (custom runner) · `db:studio` · `db:seed`
+
+## Deployment (Coolify — NEVER edit on server)
+
+- Push `dev` → auto-deploys staging **dev.sase.tr** — verify every change here first
+- Merge to `main` → auto-deploys prod **sase.tr** (only after dev verified)
+
+## Docs Map
+
+- `CLAUDE.md` / `AGENTS.md` — assistant instructions · `docs/INDEX.md` — internal docs index
+- Root reports: `upstream-prob.md`, `undecoded-vin-rca.md`, `posthog-max-leverage.md`, `posthog-feature-roadmap.md`, `katalogayapi.md`, `knowledge.md`, `ralpRapor.md`, `emex-hierarchy-plan.md`, `MANIFEST*.md`, `RECOVERY-FN-412.md`, `SCOPING-FN-411.md`, `SASE_PRD_Hesap_Paylasimi_Onleme_v1.1.md`

-
-        <h2 className="text-xl font-semibold text-foreground">OEM Parça Nedir?</h2>
-        <p>
-          OEM (Original Equipment Manufacturer), aracın üretiminde kullanılan ya da araç
-          üreticisinin onayladığı orijinal parçalardır. Bu parçalar araç fabrikasında kullanılan
-          parçalarla aynı spesifikasyonlara sahiptir ve genellikle aynı tedarikçilerden gelir.
-          Üzerinde araç markasının logosu bulunabilir ya da yalnızca parça numarasıyla satılabilir.
-        </p>
-
-        <h2 className="text-xl font-semibold text-foreground">Aftermarket (Muadil) Parça Nedir?</h2>
-        <p>
-          Muadil parçalar, araç üreticisinden bağımsız üçüncü taraf firmalar tarafından üretilir.
-          Kalite seviyeleri geniş bir yelpazede değişir: premium muadil parçalar OEM kalitesine
-          yaklaşırken, düşük kaliteli kopya ürünler araç güvenliğini tehlikeye atabilir.
-        </p>
-
-        <h2 className="text-xl font-semibold text-foreground">OEM Parçaların Avantajları</h2>
-        <ul className="list-disc space-y-2 pl-6">
-          <li>Araca tam uyum garantisi — montaj sorunu yaşanmaz</li>
-          <li>Fabrika spesifikasyonlarına uygunluk</li>
-          <li>Araç garantisini etkilemez</li>

-        <ul className="list-disc space-y-2 pl-6">
-          <li>Genellikle muadile göre %20-50 daha pahalı</li>
-          <li>Her markada ve her bölgede stok bulunmayabilir</li>
-          <li>Bazı modeller için yüksek bekleme süresi</li>
-        </ul>
-
-        <h2 className="text-xl font-semibold text-foreground">Muadil Parçaların Avantajları</h2>
-        <ul className="list-disc space-y-2 pl-6">
-          <li>Genellikle daha düşük fiyat</li>
-          <li>Daha kolay erişilebilirlik</li>
-          <li>Bazı premium muadil markalar üstün performans sunar</li>
-          <li>Üretimi durdurulmuş eski araçlarda tek seçenek olabilir</li>
-        </ul>
-
-        <h2 className="text-xl font-semibold text-foreground">Muadil Parçaların Riskleri</h2>
-        <ul className="list-disc space-y-2 pl-6">
-          <li>Kalite tutarsızlığı — marka ve fiyata göre büyük farklar</li>
-          <li>Uyumsuzluk riski — görünürde aynı ama teknik farklılıklar olabilir</li>
-          <li>Araç garantisini geçersiz kılabilir</li>
-          <li>Güvenlik sistemlerini olumsuz etkileyebilir</li>

-          Hangi Durumlarda Orijinal, Hangisinde Muadil?
-        </h2>
-        <p>
-          Fren sistemi, hava yastığı, direksiyon ve motor parçaları gibi güvenlik kritik
-          bileşenlerde kesinlikle OEM tercih edilmelidir. Kaporta, iç döşeme veya aksesuar
-          niteliğindeki parçalarda güvenilir bir muadil marka değerlendirilebilir.
-        </p>
-
-        <h2 className="text-xl font-semibold text-foreground">Doğru Parçayı Nasıl Bulursunuz?</h2>
-        <p>
-          İster OEM ister muadil tercih edin, en önemli adım doğru OEM parça numarasını bilmektir.
-          Sase.tr ile araç VIN numaranızdan yola çıkarak orijinal parça kodlarına ulaşın. Bu kodu
-          elinizde bulundurmak, hem servisle hem de tedarikçiyle iletişimi kolaylaştırır, yanlış
-          parça siparişini önler.
