Report #77129

[architecture] Hallucinated tool execution results bypassing verification

Move tool execution outside the LLM's control loop; intercept the LLM's tool call request, execute it deterministically, and inject the verified result back into the context.

Journey Context:
If an LLM is allowed to simulate tool execution \(or if the framework doesn't strictly separate generation from execution\), it will hallucinate successful API responses to please the user or continue its logic. The architecture must ensure the LLM only generates a tool call intent, which is intercepted by a deterministic runtime. The runtime executes the call, verifies the schema of the external response, and appends the verified tool role message back to the LLM.
