+# Project Architecture & Guidelines
+
+## Monorepo Layout
+- **Backend**: `./barker` (Python, managed via `uv`)
+- **Frontend**: `./bookie` (Angular, managed via `npm`/`ng`)
+- **Environment**: Root `.env` file containing shared/database variables.
+
+---
+
+## Execution Rules & Commands
+
+### Backend (`/barker`)
+- **Working Directory**: Always execute backend commands within `./barker` OR pass `--directory barker` to `uv`.
+- **Package & Script Management**:
+  - Use `uv` exclusively. Never run bare `pip` or global `python`.
+  - Run scripts/tests: `uv run python <script>` or `uv run pytest` from inside `./barker`.
+  - Manage dependencies: `uv add <package>` or `uv remove <package>`.
+- **Environment**: The root `.env` file (`../.env` relative to `barker`) contains the database connection string and secret keys.
+
+### Frontend (`/bookie`)
+- **Working Directory**: Always execute frontend commands within `./bookie`.
+- **Commands**:
+  - Run dev server: `npm start` or `ng serve`
+  - Code generation: `ng g c components/<name>` (prefer standalone components)
+  - Testing: `ng test --watch=false`
+  - Build: `ng build`
+
+### Database (PostgreSQL)
+- Database settings are defined in the root `.env`.
+- Inspect schema, run migrations, or check types strictly via database tools or `uv run` scripts inside `./barker`.
