State Sync — Conceptual Overview

Audience: Implementers, Architects, Runtime Authors Governance Rule: DGP-30

1. What State Sync Refers To

State Sync in MPLP refers to the consistency dimension that concerns how PSG (Project Semantic Graph) state remains coherent across operations. It spans VSL, PSG snapshots, and drift detection.

State Sync is not a synchronization service. It is a conceptual area describing state coherence responsibilities.

2. Conceptual Areas Covered by State Sync

Conceptual Area	Description
PSG Integrity	Relates to referential integrity across graph nodes
Snapshot/Restore	Concerns point-in-time state capture semantics
Drift Detection	Is involved in reconciling PSG vs. external state
VSL Abstraction	Relates to state persistence interfaces

3. What State Sync Does NOT Do

❌ Define specific database technologies
❌ Mandate distributed consensus protocols
❌ Prescribe conflict resolution strategies
❌ Define replication topologies

4. Where Normative Semantics Are Defined

Normative Source	What It Covers
L3 Execution & Orchestration	PSG management, VSL interface, drift detection
L1-L4 Architecture Deep Dive	Snapshot/restore, atomic transactions
