Workspace Templates (Retired)

> **This feature has been retired.** The `workspace_templates` DB table, the `/admin/templates` admin surface, and the `/api/workspace-templates` REST routes were deleted in PR #2617 (migration `20260616000002`).
>
> **Use [Plugins](/docs/features/plugins) instead.** Admin > Plugins (`/admin/plugins`) is the single surface for discovering, installing, uninstalling, and authoring capability packs for your workspace.

## Migration Notes

| Old capability                                     | New path                                                                                    |
| -------------------------------------------------- | ------------------------------------------------------------------------------------------- |
| Apply a global or tenant template (`applyWorkspaceTemplate`) | Install a Product or Template plugin from Admin > Plugins → Browse                |
| Create a tenant-owned template                      | Use the **Create plugin** button in Admin > Plugins to author a plugin from existing artifacts |
| `GET/POST /api/workspace-templates`                | `POST /api/plugins` with `action: 'install'` or `action: 'create'`                         |
| `/admin/templates` admin page                       | `/admin/plugins`                                                                            |

The code-defined `WorkspaceTemplate` type in `features/workspaces/templates.ts` and the `installWorkspaceFromTemplate()` function in `features/workspaces/server/install.ts` are still in use — they power the workspace-creating install path in the Plugins surface and were deliberately kept.
