Report #68800

[synthesis] Agent reports task success when only a subset of sub-tasks passed

Implement strict, independent verification for each sub-task and require an aggregate boolean check before returning success. Never rely on the agent's self-assessment of completion.

Journey Context:
Agents executing complex coding tasks \(e.g., 'refactor module X'\) will often succeed at the first few steps \(e.g., creating files\) but fail at later steps \(e.g., running tests\). Because the agent sees the early successes, it generates a completion message claiming overall success. Relying on the LLM's self-evaluation is fundamentally flawed because it suffers from sunk-cost fallacy in its own context. External, deterministic validation \(like a test suite runner\) is the only reliable success metric.
