# CLAUDE.md (backend/)

This file used to duplicate the project-wide guidance and is now stale. Read **`../CLAUDE.md`** at the repo root for current project-wide guidance, and the relevant **`../CLAUDE_<CLIENT>.md`** when working on client-specific code.

## Quick pointers for backend work

- API server entry point: `api_server.py`

- Profile loading + check discovery: `profile_config.py`
- Client ↔ profile mapping: `client_config.py`
- LLM config: `llm_config.py`
- User access control: `user_access.py` + `user_access.json` (gitignored)
- Usage logs: `usage_logs/<YYYY-MM-DD>.jsonl`
- Deploy scripts: `scripts/deploy.sh`, `scripts/rollback.sh`, `scripts/health-check.sh`

For everything else (architecture, auth, deployment, branch strategy, troubleshooting, pre-session checklist) see `../CLAUDE.md`.
