From 02742f2f47aeb0f64d8369faba22fa863d3c6114 Mon Sep 17 00:00:00 2001 From: ruv Date: Mon, 25 May 2026 18:14:14 -0400 Subject: [PATCH] feat(homecore/p1 iter-2): API (ADR-130) + plugins (ADR-128) scaffolds in parallel MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two new crates land in this iteration of the HOMECORE swarm: ## v2/crates/homecore-api/ (ADR-130 P1, sequential foundation) Wire-compat Axum REST + WebSocket port of HA's API. P2-tier subset: REST routes: - GET /api/ — health ping (HA parity) - GET /api/config — bare HOMECORE config - GET /api/states — all entity states - GET /api/states/{entity_id} — one state (404 if missing) - POST /api/states/{entity_id} — set state, fire state_changed - GET /api/services — services grouped by domain - POST /api/services/{domain}/{service} — call service WebSocket (/api/websocket): - auth_required → auth → auth_ok handshake (P1 accepts any non-empty bearer; P2 wires the token store) - get_states, get_config, get_services, call_service - subscribe_events (per-event-type filter, broadcasts state_changed + domain events with HA's event-envelope shape) - unsubscribe_events - ping/pong `homecore-api-server` binary boots a HomeCore on :8123, ready for a curl smoke test against the wire format. ## v2/crates/homecore-plugins/ (ADR-128 P1, concurrent foundation) Plugin runtime scaffold per ADR-128: - PluginManifest mirrors HA manifest.json (domain, name, version, dependencies, iot_class, integration_type) - HomeCorePlugin async trait + PluginId newtype + PluginError enum - PluginRuntime trait abstracting Wasmtime vs WASM3 vs InProcess. P1 ships InProcessRuntime (native Rust plugins); wasmtime + wasm3 are feature-gated default-off (Q2 not yet resolved — but the abstraction is in place so the choice is swappable). - PluginRegistry: load/unload/list by PluginId. ## Test summary - homecore: 20/20 (state machine, event bus, services, registry) - homecore-api: 4/4 (BearerAuth header parsing) - homecore-plugins:10/10 (manifest, registry, runtime, error variants) - Total: 34/34 passing ## Coordination state swarm-memory-manager namespace `homecore-impl/*`: - iteration: iter-2 ✅ - adr-127/phase: P1-complete ✅ - adr-130/phase: P1-scaffold-in-progress (now P1-complete) - adr-128/phase: P1-scaffold-in-progress (now P1-complete) ## Critical path advanced ADR-127 ✅ → ADR-130 ✅ → ADR-128 ✅ — the unblocking foundation is now done. Next iteration can fan out 129/131/132/133/134/125 concurrently. Tracking issue #798.
