Development Artifact Cleanup: ✅ BROTHER_NODE REORGANIZATION: Moved development test node to appropriate location - dev/test-nodes/brother_node/: Moved from root directory for better organization - Contains development configuration, test logs, and test chain data - No impact on production systems - purely development/testing artifact ✅ DEVELOPMENT ARTIFACTS IDENTIFIED: - Chain ID: aitbc-brother-chain (test/development chain) - Ports: 8010 (P2P) and 8011 (RPC) - different from production - Environment: .env file with test configuration - Logs: rpc.log and node.log from development testing session (March 15, 2026) ✅ ROOT DIRECTORY CLEANUP: Removed development clutter from production directory - brother_node/ moved to dev/test-nodes/brother_node/ - Root directory now contains only production-ready components - Development artifacts properly organized in dev/ subdirectory DIRECTORY STRUCTURE IMPROVEMENT: 📁 dev/test-nodes/: Development and testing node configurations 🏗️ Root Directory: Clean production structure with only essential components 🧪 Development Isolation: Test environments separated from production BENEFITS: ✅ Clean Production Directory: No development artifacts in root ✅ Better Organization: Development nodes grouped in dev/ subdirectory ✅ Clear Separation: Production vs development environments clearly distinguished ✅ Maintainability: Easier to identify and manage development components RESULT: Successfully moved brother_node development artifact to dev/test-nodes/ subdirectory, cleaning up the root directory while preserving development testing environment for future use.

* @dev Helper library to format and parse CAIP-2 identifiers
|
|
*
|
|
* https://github.com/ChainAgnostic/CAIPs/blob/main/CAIPs/caip-2.md[CAIP-2] defines chain identifiers as:
|
|
* chain_id: namespace + ":" + reference
|
|
* namespace: [-a-z0-9]{3,8}
|
|
* reference: [-_a-zA-Z0-9]{1,32}
|
|
*
|
|
* WARNING: In some cases, multiple CAIP-2 identifiers may all be valid representation of a single chain.
|
|
* For EVM chains, it is recommended to use `eip155:xxx` as the canonical representation (where `xxx` is
|
|
* the EIP-155 chain id). Consider the possible ambiguity when processing CAIP-2 identifiers or when using them
|
|
* in the context of hashes.
