+## Operational commitments
+
+CompText V7 validates whether deterministic replay reconstruction preserves:
+
+- evidence
+- constraints
+- blockers
+- dependencies
+- recovery paths
+- tool order
+- capability boundaries
+- governance/policy gates
+
+The `mcp_trace_replay` fixture family validates deterministic replay safety for tool order, validation-before-action, dependency chains, recovery paths, and capability boundaries. Registered contracts: `tool_call_order_preserved`, `validation_before_unsafe_action`, `dependency_chain_preserved`, `recovery_path_available`, `capability_boundary_respected`.

 ## Current fixture-bound signal
 
-- Three manifest-registered operational fixture families.
+- Four manifest-registered operational fixture families.
 - Standard levels: `baseline`, `mild`, `moderate`, `severe`.
 - Deterministic evaluation mode.
 - Exact rational scoring.
