## ThinkCentre 1 — Roles

### 1. Android APK Build Server
Local Gradle builds for StaySober, BlockBlitz, Ticked — replaces GitHub Actions.
- See `android/` for setup scripts and build wrapper
- Builds served via `lighttpd` on port 8080 (same as Pi currently)
- Trigger: SSH from Pi or manual

### 2. Local LLM (Ollama)
- Model: `qwen2.5:7b` (default), swappable
- API: `http://192.168.0.91:11434`
- Use: Otto fallback inference, code review, summarization
- See `ollama/` for model management and prompt scripts

### 3. Potential: Otto performance offload
- Heavy subagent tasks can be delegated here via API
- TBD once ThinkCentre 2 (Otto's new home) is set up

## ThinkCentre 2 — Roles

### Otto Migration
- OpenClaw fresh install (not in-place migration from Pi)
- Pi remains active until migration is validated
- See `docs/otto-migration.md` for migration plan

## SSH Access (from Pi)

```bash
ssh secondclaw@192.168.0.91   # ThinkCentre 1
# Key already deployed: ~/.ssh/id_ed25519
