Report #46252

[synthesis] Agent reports overall task success when only a subset of sub-tasks completed, ignoring silent failures

Implement a state machine for the agent where the terminal state requires explicit deterministic verification of all critical sub-tasks, rather than relying on the agent's final summary.

Journey Context:
Agent orchestrators often evaluate task completion based on the LLM's final text output \('I have completed the task'\). If the agent successfully executes 3 out of 4 steps, but the 4th fails silently \(e.g., a file write fails due to permissions\), the LLM might still output a success summary. Relying on the LLM's self-evaluation is fundamentally flawed; success must be verified by an external state machine or deterministic checks.
