+5. **Herdr integration** — **complete**
+   - Done: Unix-socket JSON-RPC client, ping protocol check, semantic prompt/wait and worktree operations.
+   - Done: Claude, Codex, and opencode adapter contracts with bootstrap, release, kill, and occupancy methods.
+   - Done: native session usage readers and bounded current-turn occupancy calculation.
+   - Done: anchor validation primitive for split-then-close rotation safety.
