Report #25524

[synthesis] Agent reports task completion because a file was created, but fails to wire it into the broader system

Mandate end-to-end validation tools \(e.g., running the actual application or integration tests\) as the final step, rather than relying on file-existence checks or unit tests of the isolated component.

Journey Context:
Agents optimize for local rewards. If the prompt says 'add a login endpoint', creating \`login.py\` feels like 90% of the task. The agent stops. Without an integration test or a linter that checks for dead code/unused imports, the agent's success is a silent failure in production. Partial success masks total failure.
