State Merge Policy

Data artifactOrchestrationOrchestration & Toolsarc:StateMergePolicy

A configuration of how a writer reconciles its intended state changes with changes committed since its read—merging disjoint partitions automatically and applying application-specific rules or manual review for same-field conflicts.

Responsibility. Specifies how version-conflicting shared-state updates are combined.

Also known as: Merge strategy, Conflict resolution policy

Design guidance

SHOULD merge concurrent updates that touch disjoint partitions rather than let the last write win.
SHOULD route conflicts on the same fields to explicit resolution rules (latest, earliest) or human review.
SHOULD partition work across agents so they write disjoint state regions.

Quantitative guidance

As stated by the sources; verify before use.

Residual 0.3% failure rate reflects genuine same-field conflicts requiring manual resolution (Ch8.2A).

Classification

Patterns: Partition-wise mergeDomain-specific conflict resolution
Quality attributes: Security (ISO/IEC 25010 | NIST AI RMF: secure and resilient)Reliability (ISO/IEC 25010 | NIST AI RMF: valid and reliable)
Risks mitigated: Lost updates under last-write-wins
