+- [x] **Hephaestus Autonomy**: Ported "Deep Agent" and "Intent Gate" logic to `hephaestus/gpt-5-4.ts`.
+- [x] **Ralph-loop**: Integrated runtime loop detection in `runtime-enforcement/hook.ts`.
+- [x] **State Tracking**: Updated `state-ledger` and `tool-runner` to support loop detection and successful state change verification.
 - [x] **Truth Model**: Unified `state-ledger` to securely track `success`, `verified`, and `changedState` tied to the current execution flow.
 - [x] **Runtime Enforcement**: Tightened `hook.ts` to scan only the active completion flow for deterministic tool evidence rather than relying on weak keywords or stale ledger history.
 - [x] **Completion & Query**: `complete_task` and `query_ledger` filtered strictly to verified, successful state changes from the active session flow.
