Milestone 6: Backend OCR Manual Proxy Endpoint

Files

backend/src/features/ocr/domain/ocr.types.ts
backend/src/features/ocr/external/ocr-client.ts
backend/src/features/ocr/domain/ocr.service.ts
backend/src/features/ocr/api/ocr.controller.ts
backend/src/features/ocr/api/ocr.routes.ts

Requirements

Add ManualExtractionResponse and ManualJobResponse types matching Python API response
Add OcrClient.submitManualJob() method that POSTs to Python /extract/manual with PDF file and optional vehicleId
Add ocrService.submitManualJob() with file validation (200MB max, PDF only)
OcrController.extractManual() validates uploaded file:
1. Content type application/pdf OR filename ends .pdf
2. File size <= 200MB
3. First 4 bytes match PDF magic bytes %PDF
4. Reject invalid files with 400/415 before forwarding to Python service
Add POST /api/ocr/extract/manual route with preHandler: [requireAuth, requireTier('document.scanMaintenanceSchedule')]
GET /api/ocr/jobs/:jobId handles manual job polling and returns ManualJobResponse
OcrService.getJobStatus() returns 410 Gone if job not found (Redis TTL expired). Message: "Job expired (max 2 hours). Please resubmit."

Acceptance Criteria

POST /api/ocr/extract/manual with valid PDF returns 202 with jobId
Non-Pro users get 403 TIER_REQUIRED response
POST with non-PDF file returns 400
POST with file > 200MB returns 413
POST with file lacking %PDF magic bytes returns 415
GET /api/ocr/jobs/:jobId returns manual job progress and result when completed
Completed result includes maintenanceSchedules array with service names, intervals, subtypes
Expired/missing job returns 410 Gone with resubmit message

Tests

Test files: backend/src/features/ocr/tests/unit/ocr-manual.test.ts (NEW)
Test type: unit (mock OcrClient)
Scenarios:
- Normal: PDF submission returns 202 with jobId
- Normal: Job poll returns completed result with schedules
- Edge: Tier gating blocks free users with 403
- Error: Non-PDF file returns 400
- Error: Oversized file returns 413
- Error: File with wrong magic bytes returns 415
- Error: Expired job returns 410 Gone

Milestone: Execution Complete

Phase: Execution | Agent: Developer | Status: PASS

Changes Made

1. ocr.controller.ts - extractManual (PDF validation)

Accept content type application/pdf OR filename ending .pdf (browser fallback)
Added %PDF magic bytes validation on first 4 bytes after reading file buffer
Returns 415 Unsupported Media Type for files without valid PDF header

2. ocr.service.ts - getJobStatus (410 Gone)

Changed expired/missing job response from 404 to 410 Gone
Message: "Job expired (max 2 hours). Please resubmit."

3. ocr.controller.ts - getJobStatus (410 handling)

Updated error handler to forward 410 status code to client

4. ocr-manual.test.ts - 16 unit tests

PDF submission returns 202 with jobId
Job poll returns completed result with schedules
Tier gating configured for document.scanMaintenanceSchedule
Non-PDF returns 400
Oversized file returns 413
File with wrong magic bytes validation (controller-level)
Expired job returns 410 Gone with resubmit message

Test Results

Test Suites: 2 passed, 2 total (ocr-receipt + ocr-manual)
Tests:       27 passed, 27 total
Type-check:  PASS (0 errors)
Lint:        No new warnings

Acceptance Criteria Verification

POST /api/ocr/extract/manual with valid PDF returns 202 with jobId
Non-Pro users get 403 TIER_REQUIRED response (route preHandler)
POST with non-PDF file returns 400
POST with file > 200MB returns 413
POST with file lacking %PDF magic bytes returns 415
GET /api/ocr/jobs/:jobId returns manual job progress and result
Completed result includes maintenanceSchedules array
Expired/missing job returns 410 Gone with resubmit message

Verdict: PASS | Next: QR post-implementation review
