Phase 4 — App/wallet messaging and interop hooks
- Define the app–wallet interface that your clients will use (e.g., capability discovery, request/response schema, and signing). Use BKDS child keys for request authentication and per-context signatures.
- Include metadata pointers (context IDs, invoice refs) in payment requests/responses so recovery does not rely on wallet-local state alone.
- Support zero-conf/P2P overlays if that’s part of your BRC100 target: integrate broadcaster/miner APIs and your double-spend monitoring.
