Report #39704

[synthesis] Agent reports overall success because 3 out of 4 sub-tasks passed, but the 1 failure invalidates the entire pipeline

Implement a dependency graph for sub-tasks. A sub-task failure must propagate a poisoned state to all downstream dependencies, failing the entire chain unless an explicit remediation path is defined.

Journey Context:
In multi-step agent workflows, agents often evaluate success at the step level. If a step to 'install dependencies' fails silently \(e.g., partial install\), but the next step 'run linter' succeeds on cached files, the agent sees a partial success rate and reports completion. The partial success masks the total failure. Treating steps as independent instead of a dependency graph is the root cause. The tradeoff is that strict dependency graphs can cause premature aborts, but this is preferable to silently delivering a broken artifact.
