Full inventory of all gateway and project server endpoints with caller, purpose, latency/freshness/durability requirements. Classifies each as write/read/external-webhook/frontend-asset. Maps write endpoints to target CRDT collections, proposes RPC frame shapes for read endpoints, drafts the unsigned read-RPC protocol (envelope, correlation IDs, TTL, error codes, peer-offline handling), lists in-memory state needing CRDT migration with proposed types, and defines a wave-ordered migration plan with explicit dependencies (story 665 Ed25519 auth as the blocker for write migrations).
