 | **Domain** | A bounded context under `src/app/domains/<name>/` that owns its own models, services, NgRx slice, and components — e.g. *chat*, *voice-session*, *plugins*. | "module", "feature" (Angular reserves these for different things) |
 | **Shared kernel** | Cross-domain contracts in `src/app/shared-kernel/` — wire-format models, P2P transfer utilities, plugin contracts, signaling contracts — imported by multiple domains. | "common", "core" |
-| **Infrastructure** | Technical-runtime concerns shared by domains: `persistence/` (client-side store wiring) and `realtime/` (WebSocket adapter). Not a domain. | "shared", "lib" |
+| **Infrastructure** | Technical-runtime concerns shared by domains: `persistence/` (client-side store wiring), `realtime/` (WebSocket adapter), and `mobile/` (Capacitor/native facades). Not a domain. | "shared", "lib" |
+| **Mobile facade** | An injectable service under `infrastructure/mobile/` that wraps Capacitor or web adapters so domains never import `@capacitor/*` directly. | "Capacitor service", "native plugin" |
+| **Capacitor SQLite backend** | Native persistence path selected by `DatabaseService` when `PlatformService.isCapacitor` is true; uses `@capacitor-community/sqlite` instead of IndexedDB. | "mobile database", "Capacitor DB" |
 | **Rules file** | A pure-function module suffixed `*.rules.ts` that encodes domain logic without Angular or NgRx dependencies — easy to unit-test. | "helpers", "utils" |
 | **Custom emoji** | User-created image emoji assets stored locally, synced peer-to-peer, and referenced from messages/reactions by stable `:emoji[id](name)` tokens. | "sticker", "emote" |
