 # ato
 
-First **CodeView** project — bootstrap mode.
+Standalone **Automatic Train Operation** (no ETCS, no ATP). Lean Rust controller talking to [TrainSim](../trainsim).
 
-- **Forgejo:** https://git.italiatts.online/rwsholdem/ato
-- **Mode:** bootstrap (direct push to `main` allowed)
-- **Switch to protected:** `./scripts/project-mode.sh rwsholdem ato protected`
+## Layout
 
-## Stack
+| Path | Role |
+|------|------|
+| `crates/ato-core/` | Pure control logic (zero deps, no I/O) |
+| `crates/ato-app/` | HTTP client + control loop |
+| `config/` | Replaceable parameters (`ato.default.json`) |
+| `spec/` | Interface examples (`interface.md`, JSON samples) |
 
-Scaffold your app here. Cursor and OpenClaw use this repo as the source of truth.
+## Run (via CodeView ato-lab DinD)

+```bash
+cd /root/code-view/profiles/ato-lab
+chmod +x run-e2e.sh
+./run-e2e.sh
