P261 — AIEP — Federated Causal World State Partition Protocol

Publication Date: 2026-04-12 Status: Open Source Prior Art Disclosure Licence: Apache License 2.0 Author/Organisation: Phatfella Ltd Schema: AIEP_OS_SPEC_TEMPLATE v1.0.1 — https://aiep.dev/schemas/aiep-os-spec-template/v1.0.1

Field of the Invention

[0001] The disclosure relates to partitioned causal world state graph architectures in federated AI system networks.

[0002] More particularly, the disclosure concerns a federated causal world state partition protocol, defining how a Causal World State Graph (P200) is partitioned and distributed across multiple AIEP federation nodes, with each node maintaining an authoritative partition while accessing foreign partitions through governed read interfaces.

Framework Context

[0003] This invention operates within an Architected Instruction and Evidence Protocol (AIEP) environment as defined in United Kingdom patent application number GB2519711.2, filed 20 November 2025, the entire contents of which are incorporated herein by reference.

Summary of the Disclosure

[0004] A computer-implemented federated causal world state partition protocol comprises: assigning each WorldStateNode in the global Causal World State Graph an authoritative_node_id identifying the AIEP federation node responsible for its maintenance and update; defining a PartitionMap as a metadata structure mapping WorldStateNode subgraphs to authoritative nodes by domain, jurisdiction, or explicit governance assignment; enabling authorised nodes to read foreign partition WorldStateNodes via a FederatedReadRequest authenticated over the FederationLink (P260); blocking write or update operations on foreign partition nodes — all WorldStateNode updates must be routed to the authoritative node via a PartitionUpdateProposal, which the authoritative node evaluates and commits or rejects; generating PartitionConflictRecords when two nodes simultaneously produce conflicting causal edge updates to nodes at the partition boundary, routing them to the Federation Topology Consensus protocol (P266); providing PartitionSnapshotTransfer to enable new federation nodes to bootstrap their local partition from an authoritative source; and maintaining a FederatedPartitionAuditLog of all cross-partition read and write operations.

[0005] The technical effect is modification of computing system behaviour by enabling distributed multi-node causal world state management with governed partition authority, preventing uncoordinated write conflicts while enabling federation-wide causal consistency.

Claims

[0007] A computer-implemented method for federated causal world state partition management comprising: maintaining a PartitionMap assigning WorldStateNode ownership to authoritative nodes; routing foreign partition update proposals to authoritative nodes for evaluation; detecting and routing partition boundary conflicts; providing PartitionSnapshotTransfer for bootstrapping; and maintaining FederatedPartitionAuditLogs.

[0008] A system for federated causal world state partition management comprising one or more processors and a non-transitory computer-readable medium storing instructions to execute the method of claim 1.
