Recovery and Rollback / 4 min
LangGraph State Recovery Tutorial
This guide explains how rollback tokens can wrap agent state mutations without claiming direct LangGraph integration.
Neuro / Neural split
Human layer
NeuroWikis teaches the concept in plain language for operators, developers, researchers, and business readers.
Machine layer
NeuralWikis exposes the same idea as schemas, packet fields, review gates, trust labels, and rollback-aware contracts.
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.
