Good. Here's the full picture:

## Architecture Summary
**What it is**: A FastAPI Python server that wraps the `claude` CLI binary and exposes an OpenAI-compatible REST API. Your Windows laptop (AionUI client) connects to it over HTTP.
**Can you have long conversations? — Partially yes, with a caveat.**
### How sessions work:
1. Your Windows client sends `session_id` in each request
2. The wrapper passes `--session-id <id>` to the `claude` CLI subprocess
3. Claude CLI manages its own conversation history internally on disk
4. The wrapper itself only tracks session IDs in an **in-memory dict** (lost on restart)
### The key limitation:
The wrapper **extracts only the last user message** from the `messages` array and passes that as the prompt. It relies entirely on Claude CLI's internal session files for context — it does NOT pass the full conversation history to Claude directly.
This means:
- Long conversations work **as long as the service stays running** and session files persist
- If the service restarts, new sessions start fresh (old CLI session files may still exist on disk though)
- Context length is bounded by Claude's own session/context limits
### Current status:
- Service `claude-api.service` is **running** (PID 2871732)
- Running on port **8643**
- Using `bypassPermissions` mode
### To have truly long conversations:
The architecture should work fine for multi-turn chat. Just make sure your Windows client sends the same `session_id` on every turn. Want me to check what session files exist or test a round-trip call?
