[synthesis] Agent resumes operation on partially-modified state after interruption, corrupting downstream operations

Wrap every multi-step state mutation in a transaction-like pattern: write to a temporary location, validate completeness, then atomically swap. Before any agent reads state, verify it passes a structural integrity check. If integrity fails, roll back to the last known good checkpoint rather than proceeding.

Journey Context:
File operations lack ACID transaction semantics — a partial write leaves valid-looking but inconsistent state. Agent interruptions \(timeouts, errors, user stops\) are common. The synthesis: partial state looks VALID to subsequent agents \(valid syntax, plausible structure\), so they accept it without question. A half-written JSON file with valid syntax but missing keys is more dangerous than a missing file because the missing file would trigger a clear error, while the partial file silently corrupts downstream logic. Humans recognize partial state by visual inspection; agents have no such intuition. The compounding: Agent A writes 3 of 5 config sections → interrupted → Agent B reads config, sees valid JSON, proceeds → Agent B's output depends on the 2 missing sections → produces subtly wrong results → Agent C builds on those results. The alternative of adding transactions to every file op seems heavy, but the cost of recovery from cascading corruption is always higher.
