Backend:
- Fix TicketInput ticket_id type (int|str -> str) — Pydantic 500 on numeric IDs
- Fix LLM module: add missing logger import, handle 429 and non-200 responses
- Switch LLM model to poolside/laguna-m.1:free (avoid OpenRouter rate limits)
- Add GET /api/collections/{id} endpoint to fetch single collection
- Deduplicate tickets: replace randomized hash() with deterministic
hashlib.md5 for Qdrant point IDs
- Add get_existing_ticket_ids() — scroll Qdrant before processing,
skip already-imported tickets, avoid redundant embeddings
- Multi-tenant isolation: tenant_id + collection_id in all Qdrant filters
- Fix embedding: drop incompatible openai SDK, use raw httpx
- Fix reranking: access ScoredPoint.payload via .get(), not []
- Fix chunking: expand role detection (support/operator/agent + client/user/customer)
- Fix bcrypt: downgrade to 4.0.1 (incompatible 5.x with passlib)
Frontend:
- Register: add plan selection (free/starter/pro)
- CollectionView: fetch ticket_count from backend on mount
(not only from upload response — survived page refresh)
- uploadFile: use getToken() instead of stale module-level var,
show real HTTP status in error messages
- Nginx: increase client_max_body_size to 50M for file uploads
