+Use these library pieces (import from `@duplocloud-internal/ng-common-lib`). The full catalog — every export,

 - **List** → `SearchableDatatableModule` (`<searchable-datatable [rows]="rows" (add)="…" (filter)="filterUpdate()">`
   with projected `<ngx-datatable-column>` cells, an actions `ngbDropdown`, and a status badge). Two things the list
   component **MUST** do — a plain `[rows]` + `(add)` binding that loads once in `ngOnInit` is the #1 pair of bugs:

-- **No cross-boundary toast.** The host exposes no `REMOTE_` alerts/toast token, so an extension remote can't raise

+- **Toasts reach the host, but report form errors inline.** `ngx-toastr` is a shared singleton, so the lib's
+  `SharedAlertsService` shows the host's toast from a remote — the confirm dialogs and `app-code-block-with-copy`

+  **inline** (form banner / wizard slot), beside the form the user has to fix. Never report one failure both ways.
 - **No field-level error map.** On create, `errors` is a single string, not a per-field dict — surface it as one
   message; don't expect to map it onto individual fields.
