Report #46247

[synthesis] Agent confidently executes catastrophic actions based on an unverified early assumption treated as fact

Inject a mandatory 'assumption extraction and verification' step before any state-mutating tool call, forcing the agent to list assumptions and run a read-only query to validate them.

Journey Context:
In chain-of-thought reasoning, an LLM might state 'Assuming X is true...' in step 1. By step 4, the 'Assuming' prefix is lost in the context, and X is treated as ground truth. If X is false, the agent will confidently execute destructive actions based on a cascading false premise. Read-only verification breaks the confirmation bias loop before mutation occurs, acting as a circuit breaker for the chain of reasoning.
