+Package-by-feature layout. Server context path is `/api`. Main endpoints:
 
 - `POST /api/login` — authenticates a service, stores connection ID in session
 - `GET /api/connections/status` — lists connected services for the current session
 - `DELETE /api/connections/{serviceType}` — removes a service from the session; invalidates the session if no connections remain

-Four main modules:
+Five packages:

+**`shared/`** — cross-cutting types used by more than one feature package
+
+- `ServiceType` (enum): identifies each integrated app (e.g. `HOMEBOX`); used in both `connection/` and `search/`
+- `ServiceProvider` (interface): base for `ConnectionProvider` and `SearchProvider`; declares `getServiceType()`
+- `Endpoint` (enum): API path constants for all external service calls
+- `SessionKeys`: builds session attribute names of the form `{SERVICE_TYPE}_CONNECTION_ID`
 
 **`config/`**
 
 - `CorsConfig`: env-driven allowed origins (`FRONTEND_LOCAL_URL`, `FRONTEND_PUBLIC_URL`); `allowCredentials(true)` is required for session cookies to work cross-origin
 - `SessionConfig`: JDBC-backed Spring Session with a persistent cookie (`SameSite=Lax`, `HttpOnly`)

+**`connection/`** — connecting to and persisting service credentials
 
-- `ConnectionProvider` interface: each integrated app (Homebox, WikiJS) implements `login()` and declares its `ServiceType`
+- `ConnectionProvider` interface: extends `ServiceProvider`; each integrated app implements `login()` and credential checking
 - `ConnectionService`: auto-discovers providers via Spring injection, dispatches login by `ServiceType`
 - `ConnectionController`: stores `{serviceType}_CONNECTION_ID` in `HttpSession` after login; reads session attributes to build status responses
-- Entity (`Connection`) uses **Single Table Inheritance** — one `connections` table with app-specific nullable columns
+- Entity (`ConnectionEntity`) uses **Single Table Inheritance** — one `connections` table with app-specific nullable columns
+- `HomeboxConnectionProvider` / `HomeboxEntity`: Homebox-specific implementation
 
-**`dto/`** — `ConnectionRequest`, `LoginResult`, `AuthResponse`, `ConnectionStatusResponse`
+**`search/`** — querying connected services
+
+- `SearchProvider` interface: extends `ServiceProvider`; each integrated app implements `getSearchResults()`
+- `SearchService`: auto-discovers providers via Spring injection, dispatches by `ServiceType`
+- `SearchController`: guards with session check before delegating to `SearchService`
+- `HomeboxSearchProvider`: Homebox-specific search implementation using bearer token from session

 ## What is Vaessl?
-Vaessl acts as translator between user inputs via text or image and digital management systems. It performs image and semantic search analysis before serving results from applications (e.g., Homebox, WikiJS) via REST API.
+Vaessl acts as a translator between user inputs via text or image and digital management systems. It performs image and semantic search analysis before serving results from applications (e.g., Homebox, WikiJS) via REST API.
 
 ### Core Functionality
-* **Staging:** Raw images and metadata are stored in a PostgreSQL staging table.
-* **AI-Powered Analysis:** The system utilizes **LiteLLM** as a unified gateway to process inputs via LLM of choice.
-* **Semantic Discovery:** By utilizing **Spring AI** and **pgvector**, Vaessl stores description embeddings. This allows for intent-based search (e.g., finding a "Wrench" by searching for "tool to fix a leaky pipe").
+* **Connection Management:** Users connect to supported services (e.g. Homebox) via a credential login flow. Tokens are stored in a JDBC-backed HTTP session, enabling secure multi-service connections per browser session.
+* **AI-Powered Analysis:** The system utilises **LiteLLM** as a unified gateway to process inputs via LLM of choice *(pipeline in progress)*.
+* **Semantic Discovery:** By utilising **Spring AI** and **pgvector**, Vaessl will store description embeddings to enable intent-based search (e.g., finding a "Wrench" by searching for "tool to fix a leaky pipe") *(planned)*.

 ### 2. Abstraction & Scalability
 A core requirement was to prevent vendor or application lock-in:
-* **API Abstraction:** While the initial integration targets **Homebox**, the export logic is decoupled. This allows the bridge to support other platforms like **WikiJS** by simply implementing new mapping profiles.
+* **Provider Pattern:** Both connection and search logic are fully abstracted behind `ConnectionProvider` and `SearchProvider` interfaces. Adding a new service (e.g. WikiJS) means implementing those interfaces — no changes to core dispatch logic required.
 * **AI Agnostic:** LiteLLM abstracts the AI provider, allowing the backend to switch between cloud APIs and local inference engines (Ollama) without code changes.
 
 ### 3. Testing Strategy
-* **Database Parity:** I utilize mirrored containers for development and testing (`vaessl-db` vs `vassal-test-db`). This ensures that JPA operations are tested against the real PostgreSQL engine and `pgvector` extensions rather than mocks.
-* **Frontend TDD:** A Vitest-based stack provides a fast feedback loop for the UI, ensuring component reliability before integration with the Spring Boot backend.

+| `connection/` | Login, session management, credential persistence (Single Table Inheritance) |
+| `search/` | Paged search against connected services, guarded by active session |
+| `exception/` | `GlobalExceptionHandler` via `@ControllerAdvice`; domain exceptions mapped to typed HTTP responses |

+
+| Method | Path | Description |
+| :--- | :--- | :--- |
+| `POST` | `/api/login` | Authenticates a service and stores its connection ID in the session |
+| `GET` | `/api/connections/status` | Lists all connected services for the current session |
+| `DELETE` | `/api/connections/{serviceType}` | Removes a service from the session; invalidates the session if none remain |
+| `POST` | `/api/search` | Paged search against a connected service; returns 401 if no active session |

+4. Install frontend dependencies and build the backend:
+
+```bash
+# Frontend
+cd frontend && npm install
+
+# Backend
+cd backend && ./gradlew build
+```
+
+5. Run the backend and frontend dev servers:
+
+```bash
+# Backend
+cd backend && ./gradlew bootRun
+
+# Frontend
+cd frontend && npm run dev
 ```
-3. Setup both production and test pgvector databases using the official pgvector docker image or installing the pgvector extension to you existing PostGreSQL database.
-4. Execute "npm i" and build gradle.
