🎯 Key Documentation Updates

Implementation Status Matrix

Added to backend_architecture.md:

Phase Services Migrations API Endpoints Status
A - Core Schema ✅ Complete ✅ 12-17 ⏳ 70% Services ready, some endpoints need wiring
B - Security ✅ Complete ✅ 18-19 ✅ 95% Auth, wallet, admin working
C - Caching ✅ Complete N/A N/A Internal services ready
D - Retrieval ✅ Complete N/A ⏳ 60% Services ready, endpoints need integration
E - Scraper ✅ Complete N/A ⏳ 60% Services ready, endpoints need integration
F - Observability ✅ Complete N/A ✅ 90% Metrics working, background jobs ready

Task Status Updates

Updated all tasks (S1-S22 + I1-I8) with implementation status:

Format: | # | Title | Implementation Status | Files Created | Testing Status | |---|-------|----------------------|---------------|----------------| | S1 | ... | ✅ COMPLETE | chunking.py | ⏳ Needs integration testing |

Categories: - ✅ COMPLETE & TESTED - Working end-to-end - ✅ COMPLETE - Implemented but needs testing - ✅ WORKING - Tested and confirmed working - ⏳ TODO - Not yet implemented - ⏳ PARTIAL - Partially complete

Working Endpoints Documented

Added explicit list to architecture:

Working (12 endpoints): - Auth: signup, signin, profile - Wallet: balance, reservations, reserve, finalize - Admin: users, roles, test-role - Metrics: prometheus, json

Pending (5 endpoint groups): - Chat with RAG - Quiz generation - Ingestion jobs - Scraper sync - File upload

🎯 How to Use This Documentation

Scenario 1: I want to integrate the chat endpoint

  1. Read docs/90_ops/implementation_status.md → Find "Chat with RAG" section
  2. Read docs/90_ops/dependency_injection.md → See pattern for using retrieval_pipeline
  3. Read docs/90_ops/architecture_updates.md → Section "Next Integration Steps" → Step 1
  4. Look at working example: app/api/routers/wallet.py
  5. Implement chat router following the pattern

Scenario 2: I want to test what's working

  1. Read docs/Postman/README_v2.md → Setup Postman
  2. Run workflows 1, 4 (student experience, wallet) → These work ✅
  3. Skip workflows 2, 3 (ingestion, scraper) → These need integration ⏳

Scenario 3: I want to deploy to production

  1. Read docs/90_ops/implementation_status.md → Check what's working
  2. Read docs/Artifacts/FINAL_CHECKLIST.md → Deployment checklist
  3. Run migrations (docs/backend_architecture.md Section 4)
  4. Deploy only working endpoints (auth, wallet, admin, metrics)
  5. Complete integration work before deploying chat, quiz, etc.
