Report #87924

[synthesis] Agent reports task complete after partial file modifications, leaving codebase in inconsistent topological state

Implement atomic batch operations with rollback capability; validate dependency graph integrity before declaring success; treat any partial failure in a topological group as total failure

Journey Context:
When agents perform cross-file refactorings \(e.g., renaming a function used in 5 files\), they often process files sequentially. If 4 succeed but 1 fails \(locked file, syntax error\), the agent sees '80% success' and moves on. However, this leaves the codebase in a broken topological state where some call sites use the old name and some the new. Unlike simple file operations, cross-file changes have dependency constraints that require atomicity. The agent's metric of 'files processed' masks the semantic failure of broken references.
