Report #104016

[synthesis] Agent reports success because most sub-tasks completed while a critical dependency silently failed

Define a single 'commit gate' per task: aggregate results are not surfaced until every required dependency passes an invariant check. Use compensating transactions or idempotency keys so partial failures roll back instead of persisting.

Journey Context:
Agents inherit the distributed-systems failure mode where every service returns OK except one, but the orchestrator reports success because it counts green checks. Tutorials teach retries, not saga semantics. The synthesis across API design and long-running transaction research is that agent success metrics must be defined on the critical path, not on completion percentage. A commit gate forces all-or-nothing semantics.
