Report #52540
[synthesis] Agent rolls back to checkpoint but environment has been mutated by the failed attempt making checkpoint state inconsistent
Use transactional boundaries for all agent operations — group related mutations and only commit them atomically; when rolling back, also roll back or verify all external state \(files, databases, API state\) not just the agent's internal context; implement compensating transactions for irreversible operations
Journey Context:
An agent creates a checkpoint, then modifies a shared config file and a database. The database write fails. The agent rolls back to its checkpoint — but only its internal conversation state rolls back. The config file remains modified. Now the agent proceeds with stale assumptions about the config. This is the snapshot isolation problem from databases: a checkpoint is only valid if all referenced state is also at the checkpoint version. Agents typically only checkpoint their conversation context, not the environment they've mutated. The compounding: the agent makes decisions based on a world model that diverges from reality at the checkpoint boundary, and each subsequent step widens the gap. The fix applies ACID transaction principles to agent operations.
