+# Drivers Bot Platform Plan
+
+## 1. Current Architecture Summary
+
+- FastAPI serves JSON API and static Telegram Mini App files from `web/`.
+- aiogram bot opens the Mini App with `WEBAPP_URL` and talks to the API through `INTERNAL_API_TOKEN`.
+- Users are Telegram-backed; user API access is based on verified Telegram WebApp `initData`.
+- Current domain model covers personal garage use: `users`, `cars`, `fuel_entries`, `service_entries`, catalog tables, push subscriptions, service center stubs, and inbox messages.
+- Existing MVP must remain compatible: personal cars, fuel logs, service logs, reminders, stats, catalog, OCR text parsing, bot start/cars/add_car flows.
+
+## 2. Target Product Model
+
+Drivers Bot evolves from a personal car diary into a controlled multi-sided platform:
+
+- Vehicle owners manage cars and personal expense/service history.
+- Verified service centers create service visits and work items for vehicles.
+- Owners control access to vehicles and confirm sensitive changes.
+- Service centers are tenants: employees can only see their own service center data and vehicle data for granted access or active visits.
+- Moderators/admins verify service centers, inspect disputes, and audit platform actions.
+
+Open product decisions:
+
+- Whether verified service centers can create temporary vehicle records before owner claim. Initial implementation allows service visits only when vehicle exists or owner grants access; temporary cards are deferred to avoid ownership fraud.
+- Whether `service_entries` and `service_visits` should be merged. Initial implementation keeps existing `service_entries` for MVP and adds `service_visits/work_items` as the platform layer.
+
+## 3. UX/UI Flows
+
+Owner flows:
+
+1. Create/edit vehicle manually with make, model, year, plate, VIN, odometer, oil data, and service norms.
+2. Open "Connected services" and grant/revoke service access using invite/access code or request from service center.
+3. See service history from personal entries and service-center visits.
+4. Receive confirmation requests for service visits and critical vehicle changes.
+5. Confirm, dispute, reject, or hide sensitive details.
+
+Service center flows:
+
+1. Create service profile.
+2. Submit verification details/documents.
+3. After verification, invite employees.
+4. Employee starts a visit, searches/scans plate/VIN, requests access if needed, then adds work items.
+5. Manager/owner completes visit, moving it to owner confirmation.
+
+Admin/moderator flows:
+
+1. Review pending service centers.
+2. Approve/reject/suspend service centers.
+3. Inspect audit log, disputes, and suspicious searches.
+
+## 4. Roles And Permissions
+
+Platform roles:
+
+- `user`: owns/drives/views vehicles according to `vehicle_access`.
+- `service_owner`: owns a service center, manages verification and employees.
+- `service_employee`: works inside one service center.
+- `verifier` / `moderator`: reviews verification and disputes.
+- `admin`: full moderation and platform operations.
+
+Service employee roles:
+
+- `receptionist`: create visits and access requests.
+- `mechanic`: add work items and recommendations.
+- `manager`: complete visits and manage employees.
+- `owner`: manage center, employees, and verification.
+
+Permission rule: backend checks every endpoint with `current_user`; frontend permissions are only UX hints.
+
+## 5. Data Access Rules
+
+- Owners can see and modify their active vehicles and personal logs.
+- A service center can see only:
+  - its own profile, employees, verification requests, visits;
+  - minimal masked vehicle data during access request;
+  - visit details for vehicles with active access or active visit.
+- Plate/VIN search must not reveal owner identity, Telegram ID, phone, full expense history, or sensitive attributes.
+- `user_id` from request body is not trusted.
+- `vehicle_id` access requires owner role, active `VehicleAccess`, or a service visit scoped to the service center.
+
+## 6. Anti-Fraud Model
+
+- No automatic ownership claim by VIN/license plate.
+- VIN and license plate are normalized; VIN is unique when present.
+- License plate uniqueness is scoped by country.
+- Plate/VIN changes create audit and may create `VehicleDataChangeRequest`.
+- Service-created visits are not trusted until owner confirmation.
+- Critical fields requiring owner approval: VIN, license plate, odometer, oil type/volume, service norms, engine parameters.
+- Service center actions are auditable and cannot be hard-deleted.
+- Rate limiting for plate/VIN/OCR/access requests is required before broad public launch. Initial implementation logs searches/actions; hard rate limit can be added via middleware/Redis.
+
+## 7. Database Changes
+
+Extend `cars` as Vehicle-compatible table:
+
+- `license_plate_display`
+- `license_plate_normalized`
+- `license_plate_country`
+- `vin_normalized`
+- unique `vin_normalized` when not null
+- unique `(license_plate_country, license_plate_normalized)` when not null
+
+New tables:
+
+- `vehicle_access`
+- `service_center_verifications`
+- `service_employees`
+- `service_visits`
+- `service_work_items`
+- `vehicle_data_change_requests`
+- `audit_logs`
+
+Existing tables kept:
+
+- `service_entries` remain the personal/MVP service diary.
+- `service_centers` is expanded instead of replaced.
+
+## 8. API Design
+
+Owner API:
+
+- `GET /api/me`
+- `GET /api/my/vehicles`
+- `POST /api/my/vehicles`
+- `PATCH /api/my/vehicles/{vehicle_id}`
+- `GET /api/my/vehicles/{vehicle_id}/service-history`
+- `POST /api/my/vehicles/{vehicle_id}/grant-service-access`
+- `POST /api/service-visits/{visit_id}/confirm`
+- `POST /api/service-visits/{visit_id}/dispute`
+- `POST /api/vehicle-change-requests/{id}/approve`
+- `POST /api/vehicle-change-requests/{id}/reject`
+
+Service API:
+
+- `POST /api/service-centers`
+- `GET /api/service-centers/my`
+- `POST /api/service-centers/{id}/verification`
+- `POST /api/service-centers/{id}/employees/invite`
+- `GET /api/service-centers/{id}/visits`
+- `POST /api/service-centers/{id}/visits`
+- `POST /api/service-visits/{id}/work-items`
+- `POST /api/service-visits/{id}/complete`
+- `POST /api/service-centers/{id}/vehicle-access/request`
+
+Admin API:
+
+- `GET /api/admin/service-centers/pending`
+- `POST /api/admin/service-centers/{id}/verify`
+- `POST /api/admin/service-centers/{id}/reject`
+- `POST /api/admin/service-centers/{id}/suspend`
+- `GET /api/admin/audit-log`
+- `GET /api/admin/disputes`
+
+## 9. OCR Design
+
+OCR is provider-based:
+
+- `OCRProvider` interface.
+- `StubOCRProvider` default: extracts candidates from text/file name and never claims real image OCR.
+- Future: `TesseractOCRProvider`, cloud OCR, or VLM provider.
+
+OCR response:
+
+```json
+{
+  "recognized_text": "...",
+  "candidates": [
+    {"type": "license_plate", "value": "...", "confidence": 0.91}
+  ]
+}
+```
+
+OCR endpoints create suggestions only. They must not update vehicle data directly.
+
+## 10. Migration Plan
+
+1. Add nullable columns and new tables with conservative constraints.
+2. Backfill current `cars.plate_number`/`cars.vin` into display/normalized columns where valid.
+3. Create owner `vehicle_access` rows for existing `cars.owner_id`.
+4. Add unique indexes for VIN and country/plate.
+5. Keep existing endpoints compatible while new `/api/my/*` and service-center endpoints roll out.
+
+## 11. Test Plan
+
+Backend:
+
+- VIN normalization/validation.
+- Plate normalization.
+- Owner cannot claim another vehicle by VIN/plate.
+- Service employee cannot see another service center data.
+- Unverified service center cannot complete trusted visits.
+- Owner confirmation changes visit status.
+- Critical data change request approve/reject updates only after owner action.
+- OCR endpoint returns candidates without writing data.
+- Existing fuel/service/reminders tests remain green.
+
+Manual:
+
+- Telegram Mini App opens with local test bot.
+- Existing garage/fuel/service flows still work.
+- Direct browser page shows Telegram-only message unless dev auth enabled.
+
+## 12. Implementation Phases
+
+Phase 1:
+
+- Expand models and migrations.
+- Add permission helpers.
+- Add basic service center create/my/verification/employee flow.
+
+Phase 2:
+
+- Add vehicle identity fields, ownership/access model.
+- Add service visits/work items.
+- Add owner confirmation and vehicle data change requests.
+
+Phase 3:
+
+- Add OCR provider interface and license plate/VIN/service document endpoints.
+- Add lightweight frontend sections for service center panel, visits, confirmations, OCR.
+- Add admin moderation endpoints.
+
+Phase 4:
+
+- Add tests, README, `.env.example`.
+- Run Docker compose, Alembic, API health, bot startup with local test token.
+- Keep production deploy separate unless explicitly requested.

 Расход топлива считается по интервалам между полными баками (`is_full_tank=true`). Если данных мало, API возвращает `null`, а не выдуманную цифру.

 ## OCR

 Настоящий OCR по фото/PDF пока не подключен. Endpoint `POST /api/ocr/parse-text-receipt` честно разбирает только текстовый чек. Старый `/api/ocr/fuel-receipt` оставлен как deprecated-совместимость.
+
+Новая OCR-архитектура использует заменяемый provider:
+
+- `OCRProvider`
+- `StubOCRProvider`
+- будущие `TesseractOCRProvider`, cloud OCR или VLM provider
+
+OCR возвращает кандидаты и не меняет данные автомобиля напрямую:
+
+```json
+{
+  "recognized_text": "VIN KMHCT41BAHU123456",
+  "candidates": [
+    {"type": "vin", "value": "KMHCT41BAHU123456", "confidence": 0.84}
+  ]
+}
+```
+
+## Platform Roadmap
+
+Проектное расширение в сторону владельцев авто и СТО описано в `PROJECT_PLAN.md`. В код добавлен первый совместимый слой платформы:
+
+- расширенный `ServiceCenter`;
+- верификация СТО;
+- сотрудники СТО;
+- `VehicleAccess`;
+- `ServiceVisit`;
+- `ServiceWorkItem`;
+- `VehicleDataChangeRequest`;
+- `AuditLog`;
+- нормализация VIN и госномера.
+
+СТО не получает персональные данные владельца по VIN/номеру. Поиск возвращает только минимальную маскированную карточку и пишет действие в аудит. Критичные изменения автомобиля проходят через запрос подтверждения владельцем.
