- move runtime policy/diag contracts to domain-owned facade and remove control_plane leapfrog usage - enforce single declaration point for direct debug config in domain public API (constraint #6) - harden timeout/idempotent semantics in REST/voice/printer/wifi/ble paths
Platform Layer
Purpose: hardware and system resource abstraction only.
Allowed examples:
- Wi-Fi/BLE driver wrappers
- NVS/time/RTOS/system adapters
- board-specific IO and transport bindings
Rules:
- Expose stable APIs in
include/. - Keep private headers in
internal/. - Do not depend on
domain,control_plane, orapp_composition.
