 Model-generated arguments are validated against each `ToolSpec.input_schema` before authorization or execution. Authorization policies receive the resolved tool identity, arguments, provider/source metadata, tenant/security context, and model-visible set. Calls outside the routed set fail closed.
 
-Every run also returns per-stage telemetry for catalog discovery, scope/routing, model calls, schema validation, authorization, execution, and recovery.
+After authorization, v0.7.1 applies per-run replay/idempotency protection before invoking the executor. `ToolSpec.idempotency` supports `auto`, `none`, `call_id`, and `arguments`; `auto` uses argument-signature protection for high/critical-risk tools and call-ID protection for other tools. Only successful executions are cached, so failures remain eligible for bounded recovery without silently repeating a protected successful side effect.

+Executor-returned identity cannot override the canonical tool identity that passed routing, validation, and authorization. Conflicting executor identity is retained only as audit metadata, and structured tool results are serialized deterministically for model continuation.

+Every run also returns per-stage telemetry for catalog discovery, scope/routing, model calls, schema validation, authorization, replay reuse, execution, and recovery, together with replay and routing provenance.
