Report #44472

[synthesis] Partial state mutation with no rollback leaves system in inconsistent state

Before any multi-file or multi-resource modification, create an explicit checkpoint \(git commit, snapshot, backup\). Structure modifications as gather-validate-apply: collect all changes first, validate them as a unit, then apply atomically. If any step fails, roll back to the checkpoint before retrying. Never allow partial modifications to persist uncommitted.

Journey Context:
Agents operate step-by-step: modify file A, then file B, then file C. If the agent fails or is interrupted at file B, files A and C are in different states. The next agent \(or retry\) assumes consistency and builds on the partial state. This is the agent equivalent of a partial database transaction without rollback — a well-solved problem in database theory but absent from most agent frameworks. The compounding is severe: partial state is worse than no state because it looks valid but violates invariants. Downstream agents read file A \(modified\) and file C \(unmodified\), derive incorrect conclusions, and make decisions that further corrupt state. The transactional pattern \(checkpoint-validate-apply-rollback\) adds overhead but prevents the most insidious class of compounding failures.
