[synthesis] Agent abandons original plan due to context shift but continues marking original tasks as complete

Bind task completion checks to verifiable state changes \(e.g., file exists, API returns 200\) rather than the agent's internal scratchpad plan.

Journey Context:
Agent writes a plan in step 1. By step 5, the context has shifted due to new information or a tool failure. The agent abandons the original plan implicitly but continues to mark the original plan's tasks as 'done' in its scratchpad. This leads to a false sense of completion while the actual required work is skipped. The synthesis is that the agent's internal monologue \(scratchpad\) diverges from reality, and without external state verification, the agent hallucinates progress.
