# cross-session-handoff
Manages `.arcgentic/state.yaml` as the shared state medium across multiple AI
sessions.
## Commands
```bash
arcgentic cross-session-handoff read
arcgentic cross-session-handoff write --session-id dev-session --updates '{"current_phase":"dev"}'
arcgentic cross-session-handoff snapshot --session-id audit-session
arcgentic cross-session-handoff acquire-lock --session-id dev-session --ttl 600
arcgentic cross-session-handoff release-lock --session-id dev-session
```
## Rules
- Reads do not acquire a lock.
- Writes acquire a TTL lock, write through a temp file, then rename atomically.
- Snapshots go to `.arcgentic/state-history/`.
- A session must not overwrite another non-expired lock.
