[synthesis] Agent confidently executes multiple consecutive steps based on an initial hallucinated assumption

Inject a 'state validation' step at critical state transitions where the agent verifies the output of the previous step against the original goal before proceeding.

Journey Context:
When an agent hallucinates a file path or variable name in step 1, it doesn't throw an error if the tool accepts strings. Step 2 uses the hallucinated string, and the agent rationalizes the empty or incorrect output. People try to fix this by adding more instructions or constraints, but the root cause is the lack of a feedback loop at the boundary of state mutation. The tradeoff is increased latency and token cost per step versus preventing catastrophic drift. It is the right call at mutation boundaries because recovering from a deep cascade is exponentially more expensive.
