## Problem

Agent workflows may mutate state across several nodes, and a later failure can reveal that the memory or tool change was unsafe.

## Failure mode

Basic checkpointing stores bytes or state snapshots but may not record semantic reason, evidence, or permitted rollback scope.

## Architecture pattern

Wrap each durable state mutation in a reversible commit record containing target state, prior state reference, reviewer evidence, transition hash, and rollback token.

## Conceptual record

{"commitId":"commit-example","stateGraph":"conceptual","targetNode":"memory-write","rollbackToken":{"targetCommitId":"commit-example","rollbackScope":"packet-adoption"}}

## FAQ

### Can this be used without credentials?
Public reading is allowed. Protected mutations require reviewer or operator authorization.

### Is this an official integration?
Only if the page says so. Otherwise it is a conceptual pattern or reference contract.

### What is the safe fallback?
Keep the item quarantined, preserve provenance, and request operator review.

### What should agents read next?
Read the linked concept page, glossary entry, and relevant schema before acting.
