[synthesis] Agent proceeds with dependent operations after partial file writes causing architectural inconsistency

Treat partial completion as total failure for dependency graphs; implement atomic transaction boundaries where either all artifacts in a dependency group are written and validated, or none are, before any dependent reasoning occurs.

Journey Context:
When an agent writes 3 of 5 files in a refactoring task, it often updates its plan to reflect '60% complete' and proceeds to use those 3 files as context for the next phase \(e.g., generating tests or imports\). However, the missing 2 files may contain interface definitions that the 3 files now reference incorrectly. The agent doesn't see compilation errors yet because it hasn't validated the partial state. Common mistakes include 'incremental progress tracking' or 'checkpointing' that treats files as independent. The synthesis reveals that for agent tasks with cross-dependencies, partial success is worse than total failure because it masks dependency violations and creates 'architectural debt' that compounds silently. You must enforce all-or-nothing commits at module boundaries.
