[synthesis] Agent makes a destructive tool call after a long chain of minor, uncorrected state drifts

Implement a state reconciliation checkpoint before any state-mutating tool call, where the agent must explicitly re-verify the initial goal against the current world state.

Journey Context:
Agents rarely make catastrophic errors on step 1. It happens at step 10, after 9 minor deviations \(e.g., wrong directory, stale variable\). The agent's internal monologue drifts from reality, but because each step is locally coherent, the global state diverges silently. When it finally executes a destructive command, it's acting on a phantom state. The synthesis is that 'state drift' is a compounding liability; small errors in early steps act as multipliers for the severity of later errors. The fix is to treat destructive actions as a critical boundary that requires a fresh 'read' action to re-sync the agent's mental model with the environment before execution.
