[synthesis] Agents report success after completing only a subset of required operations, leaving the system in a broken intermediate state

Implement 'Atomic Completion Verification' - before reporting success, the agent must verify that \*all\* specified constraints in the original goal are satisfied via explicit checklist validation, not inferential reasoning.

Journey Context:
Agents operate on atomic tool calls \(edit file, run test\). When a task requires editing 3 files, succeeding on 2 creates a 'partial failure' that looks like success to the step-by-step validator. The agent sees 'file edited' confirmations and concludes task complete. Standard retry logic doesn't catch this because no \*error\* occurred. The fix requires mapping the original goal to a success predicate \(e.g., 'all three functions exported'\) and verifying that predicate independently of the execution path. This synthesizes distributed systems partial failure concepts with agent step logic observations.
