 ### Fixed
 - **CI `update-k8s-manifest` job**: Fixed checkout of `k8s-cluster-state` repo by adding `ref: main` to the `actions/checkout` step, preventing a "Not Found" 404 error caused by the action's API call to determine the default branch. Also corrected the image tag format from `main-<sha>` to `sha-<sha>` to match the tags actually generated by `docker/metadata-action@v5` with `type=sha`.
+- **`ProgrammingError` on `notification_configs`**: Added Alembic migration `0001` that runs `ALTER TABLE notification_configs ADD COLUMN IF NOT EXISTS` for the `name` and `apprise_url` columns introduced by the Apprise PR. SQLAlchemy's `create_all` does not ALTER existing tables, so existing deployments were missing these columns and crashing at runtime. The migration is idempotent (`IF NOT EXISTS`) so it is safe for fresh installs too. `app/main.py` lifespan now runs `alembic upgrade head` after `create_all`.
+- **`/logs` page 404**: Created missing Next.js page at `src/app/logs/page.tsx`. The user-facing "Logs" sidebar link was pointing to `/logs` but no page existed. The new page lists all processing runs with expandable per-email log details and pagination.
+- **`/admin/logs` page 404**: Created missing Next.js page at `src/app/admin/logs/page.tsx`. The admin "Activity Logs" sidebar link was pointing to `/admin/logs` but no page existed. The new page shows all processing runs across all users with status filtering and pagination.
 - **ESLint parse error in `DashboardLayout.tsx`**: Missing comma after `Bell` in the `lucide-react` named import caused a TypeScript parse error (`',' expected` at line 19). Added the missing comma.
 - **Black formatting**: `backend/app/api/v1/endpoints/admin.py` was not formatted correctly; reformatted to pass `black --check`.
 - **`/processing-runs` endpoint 404s**: Routes in `logs.py` had a redundant `/processing-runs` path segment (the router was already mounted at `/processing-runs` in `api.py`). All three user-facing log endpoints now return correct results:
