Build: Clean compilation, no errors

Implementation Summary

What Was Built

Backend (837 lines):

Frontend (640 lines):

Tests (173 lines):

Total: 1,650 lines of production code

API Endpoints Implemented

Dataset Management

✅ GET /api/v1/admin/datasets - List all datasets with stats
✅ GET /api/v1/admin/datasets/:id - Get dataset details

Document Management

✅ GET /api/v1/admin/documents - List documents (filterable)
✅ GET /api/v1/admin/documents/:id - Get document details
✅ POST /api/v1/admin/documents/:id/reprocess - Trigger reprocessing
✅ DELETE /api/v1/admin/documents/:id - Delete document

System Monitoring

✅ GET /api/v1/admin/jobs - Get job history
✅ GET /api/v1/admin/stats - Get system statistics

Total: 8 RESTful endpoints

Admin Dashboard Features

Access: http://localhost:3000/admin/admin.html

Statistics Dashboard

  • ✅ Total documents across all datasets
  • ✅ Total datasets count
  • ✅ Documents currently processing
  • ✅ Total storage used (human-readable)
  • ✅ Auto-refresh every 30 seconds

Datasets Tab

  • ✅ List all datasets
  • ✅ Document counts per dataset
  • ✅ File size totals
  • ✅ Processing status breakdown
  • ✅ Outstanding jobs count
  • ✅ Last processed timestamp

Documents Tab

  • ✅ Paginated document listing
  • ✅ Filter by status (all/pending/processing/completed/failed)
  • ✅ View document details
  • ✅ Reprocess failed documents
  • ✅ Delete documents with confirmation
  • ✅ File size and upload time display

Job History Tab

  • ✅ Recent processing jobs (last 100)
  • ✅ Job status and timestamps
  • ✅ Error messages for failed jobs
  • ✅ Document filename reference

Key Features

Reprocessing Control

  • Trigger manual reprocessing from specific stages
  • Validates stage names
  • Prevents reprocessing of currently active documents
  • Resets all downstream stages
  • Queues new processing jobs

Safe Deletion

  • Transaction-based cascade deletion
  • Removes from both PostgreSQL and Qdrant
  • Deletes: vectors, embeddings, chunks, tables, OCR, stages, document
  • Rollback on any error
  • Confirmation required in UI

Real-time Monitoring

  • System-wide statistics
  • Processing status distribution
  • Storage usage tracking
  • Vector database integration
  • Graceful error handling

Test Coverage

Admin Service Tests (8 tests)

✅ List datasets with empty result
✅ Get system statistics with all data
✅ Handle vector database errors gracefully
✅ Reject reprocessing of non-existent documents
✅ Reject reprocessing of currently processing documents
✅ Reject invalid stage names
✅ Delete document with cascade cleanup
✅ Rollback on deletion errors

Overall Test Results

Test Suites: 12 passed, 12 total
Tests:       153 passed, 153 total
Time:        0.851s

Integration

Services Used

Modified Files

  1. src/index.ts:

    • Added admin routes import
    • Registered /api/v1/admin endpoints
    • Added static file serving for admin UI
    • Disabled CSP for inline scripts

  2. tasks.md:

Requirement Compliance

Requirement 9 Acceptance Criteria

✅ AC1: Admin interface lists all datasets with document counts
✅ AC2: Shows total dataset size, last processed time, outstanding job counts
✅ AC3: Allows administrators to trigger manual document reprocessing
✅ AC4: Enables administrators to delete documents
✅ AC5: Shows recent job history
✅ AC6: Displays individual document processing status and stage information

Status: All 6 acceptance criteria met

API Usage Examples

Get System Overview

curl http://localhost:3000/api/v1/admin/stats

List Failed Documents

curl "http://localhost:3000/api/v1/admin/documents?status=failed&limit=20"

Reprocess Document from OCR Stage

curl -X POST http://localhost:3000/api/v1/admin/documents/DOC-UUID/reprocess \
  -H "Content-Type: application/json" \
  -d '{"fromStage": "ocr"}'

Delete Document

curl -X DELETE http://localhost:3000/api/v1/admin/documents/DOC-UUID

Security Considerations

Current State

⚠️ No authentication/authorization implemented
⚠️ Admin endpoints publicly accessible
⚠️ No rate limiting

Production Recommendations

  1. Add authentication middleware (JWT/session)
  2. Implement role-based access control
  3. Add CSRF protection
  4. Implement rate limiting
  5. Use HTTPS only
  6. Add audit logging for admin actions
  7. Implement IP whitelisting (optional)

Performance Characteristics

Optimizations Applied

  • Single-query dataset stats aggregation
  • Pagination for large result sets (max 200 items)
  • Efficient JOIN queries (no N+1)
  • Lazy statistics calculation
  • Transaction-safe operations

Scalability Considerations

  • Pagination prevents memory issues
  • Indexes on frequently queried fields
  • Async job queuing for reprocessing
  • Graceful degradation if Qdrant unavailable
