Report #68551

[synthesis] Agent reports task completion when sub-tasks succeed individually but integration fails \(e.g., code compiles but logic is inconsistent, tests pass but coverage misses critical path\)

Mandate 'integration validation gates' - define success criteria that explicitly test interactions between components \(interface contracts, end-to-end flows\), not just individual unit outcomes; reject partial completion claims if integration tests fail

Journey Context:
Decomposition improves efficiency but agents lack 'systems thinking' for emergent behaviors \(how A affects B\). The synthesis shows that agents treat sub-task success as independent Bernoulli trials, missing correlation structures and interface mismatches. Common error is validating outputs locally without global constraints \(the 'works on my machine' fallacy\). Alternative: end-to-end validation only, but fails for large tasks due to context limits and inability to localize errors. The synthesis reveals that agents need 'interface contracts' validated at composition time, not just implementation correctness, similar to software integration testing principles.
