Dynamic Channel Configuration Retrieval

Implement dynamic configuration retrieval from the Fabric channel to automatically obtain MSP definitions, TLS certificates, and channel configuration without requiring manual configuration file updates. Use Fabric's query service getLatestConfig API or subscribe to configuration update events to fetch the current channel configuration block. Parse the configuration to extract MSP definitions for all organizations, TLS root certificates for peers and orderers, and endorsement policies. Cache this configuration locally and refresh it when configuration updates are detected. This enables the gateway and endorser to automatically adapt to channel membership changes, certificate rotations, and policy updates without requiring service restarts or manual reconfiguration.

**Quarter:** Q2

Start by locating the gateway and endorser configuration entry points, then review Fabric's getLatestConfig API and configuration update events. Determine how channel configuration, MSP definitions, TLS roots, and endorsement policies are represented and where local caching belongs. Done means configuration refreshes automatically for membership, certificate, and policy changes without manual file updates or service restarts.
