+# Archived Platform Services
+
+## vehicles/
+**Archived**: 2025-11-03
+**Reason**: Integrated into backend as platform feature module
+
+This Python FastAPI service was replaced by the TypeScript platform feature in `backend/src/features/platform/`.
+
+### What Was This Service?
+The vehicles platform service provided:
+- Vehicle hierarchical data (makes/models/trims/engines) via PostgreSQL
+- VIN decoding via NHTSA vPIC API with circuit breaker
+- Redis caching (6-hour TTL for vehicle data, 7-day TTL for VIN decode)
+- JWT authentication
+- Health checks and monitoring
+
+### Why Was It Archived?
+1. **Architecture Simplification**: Reduced from 6 to 5 containers
+2. **Technology Stack Unification**: Consolidated on Node.js/TypeScript
+3. **Development Experience**: Eliminated inter-service HTTP calls
+4. **Deployment Complexity**: Simplified Docker compose configuration
+
+### Migration Details
+See: `docs/PLATFORM-INTEGRATION-MIGRATION.md`
+
+### New Implementation
+Location: `backend/src/features/platform/`
+API Endpoints: `/api/platform/*`
+Language: TypeScript (Fastify)
+Database: Same PostgreSQL vehicles schema
+Caching: Same Redis strategy
+

+### Restoration (if needed)
+If you need to restore this service:
+```bash
+# 1. Move back from archive
+mv archive/platform-services/vehicles mvp-platform-services/
+
+# 2. Restore docker-compose.yml configuration
+git restore docker-compose.yml
+
+# 3. Rebuild containers
+docker compose down
+docker compose up -d
+
+# 4. Verify 6 containers running
+docker compose ps
+```
+
+### Permanent Deletion
+This directory can be permanently deleted after:
+1. Platform feature proven stable in production (30+ days)
+2. All stakeholders approve removal
+3. Backup created of this archive directory
+4. Git history confirms safe recovery if needed
+
+Do not delete before 2025-12-03 at earliest.

+# MVP Platform Vehicles Service
+
+For full platform architecture and integration patterns, see `docs/PLATFORM-SERVICES.md`.
+
+## Schema Bootstrapping (Docker-First)
+- Database: PostgreSQL, service `mvp-platform-vehicles-db`.
+- On first start, schema files from `mvp-platform-services/vehicles/sql/schema` are executed automatically because the folder is mounted to `/docker-entrypoint-initdb.d` in `docker-compose.yml`.
+- Files run in lexicographic order:
+  - `001_schema.sql` – creates `vehicles` schema and tables
+  - `002_constraints_indexes.sql` – adds uniques and indexes
+  - `003_seed_minimal.sql` – seeds minimal dropdown data for sanity checks
+
+## When Do Files Run?
+- Only on the initial database initialization (i.e., when the Postgres data volume is empty).
+- Subsequent `make start` runs will not reapply these files unless you reset the volume.
+
+## Applying Schema Changes
+- Option 1 (fresh reset):
+  1. `make clean` to remove volumes
+  2. `make start` (the `.sql` files will be reapplied)
+- Option 2 (manual apply to existing DB):
+  - Exec into the DB container and run the SQL files in order:
+    ```bash
+    docker compose exec mvp-platform-vehicles-db bash -lc "psql -U mvp_platform_user -d vehicles -f /docker-entrypoint-initdb.d/001_schema.sql"
+    docker compose exec mvp-platform-vehicles-db bash -lc "psql -U mvp_platform_user -d vehicles -f /docker-entrypoint-initdb.d/002_constraints_indexes.sql"
+    docker compose exec mvp-platform-vehicles-db bash -lc "psql -U mvp_platform_user -d vehicles -f /docker-entrypoint-initdb.d/003_seed_minimal.sql"
+    ```
+
+## Quick Start
+```bash
+make start
+make logs-platform-vehicles   # View API + DB logs
+```
+
+## Endpoint Summary (Auth Required: Authorization: Bearer <API_KEY>)
+- `GET /api/v1/vehicles/years` → `[number]`
+- `GET /api/v1/vehicles/makes?year=YYYY` → `{ makes: [{id,name}] }`
+- `GET /api/v1/vehicles/models?year=YYYY&make_id=ID` → `{ models: [...] }`
+- `GET /api/v1/vehicles/trims?year=YYYY&make_id=ID&model_id=ID` → `{ trims: [...] }`
+- `GET /api/v1/vehicles/engines?year=YYYY&make_id=ID&model_id=ID&trim_id=ID` → `{ engines: [...] }`
+
+## Notes
+- Transmissions and performance tables exist for future use; no endpoints yet.
+- VIN decode endpoints are pending rebuild and not documented here.
