+# PiRC-249: Cross-Chain State Synchronization
+
+## 1. Executive Summary
+This standard ensures that the global state of the 7-Layer Colored Token System remains perfectly synchronized between the Pi Network EVM and the Stellar Soroban environment, enforcing the Parity Invariant across chains.
+
+**Dependencies**: PiRC-207, PiRC-211
+**Status**: Complete reference implementation
+
+## 2. Architecture
+- Merkle root state syncing
+- Parity Invariant cross-chain validation
+- Automated state reconciliation
+
+## 3. Reference Smart Contracts
+**Solidity**: `contracts/PiRC249StateSync.sol`
+**Soroban**: `contracts/soroban/src/state_sync.rs`
+
+## 4. Implementation Roadmap
+- Phase 1: Merkle root generation and broadcasting
+- Phase 2: Cross-chain state verification
+- Phase 3: Automated reconciliation triggers

+# PiRC-260: Registry v3 (The Overarching Finalization)
+
+## 1. Executive Summary
+This is the capstone standard of the Pi Network architecture. PiRC-260 (Registry v3) unifies all previous 259 standards into a single, cohesive, and upgradeable master registry. It enforces the ultimate Parity Invariant across all layers, protocols, and chains.
+
+**Dependencies**: PiRC-207, PiRC-230, PiRC-254
+**Status**: Complete reference implementation
+
+## 2. Architecture
+- Master routing and module resolution
+- Ultimate Parity Invariant enforcement
+- Global upgradeability via PiRC-212 Governance
+
+## 3. Reference Smart Contracts
+**Solidity**: `contracts/PiRC260RegistryV3.sol`
+**Soroban**: `contracts/soroban/src/registry_v3.rs`
+
+## 4. Implementation Roadmap
+- Phase 1: Module resolution and routing
+- Phase 2: Integration of all PiRC standards
+- Phase 3: Mainnet Genesis deployment
