 to enact the following, basic troubleshooting steps:
-- **For Blob types** (using the `Packages::PackageFile` component as an example)
-
-  - Find registry records that failed to sync:
-
-    ```ruby
-    Geo::PackageFileRegistry.failed
-    ```
-
-    The term registry records, in this case, refers to registry tables in the
-    Geo tracking database. Each record, or row, tracks a single replicable in the
-    main GitLab database, such as an LFS file, or a project Git repository. Here
-    are some other Rails models that correspond to Geo registry tables that can
-    be queried like the above:
-
-    ```plaintext
-    CiSecureFileRegistry
-    ContainerRepositoryRegistry
-    DependencyProxyBlobRegistry
-    DependencyProxyManifestRegistry
-    JobArtifactRegistry
-    LfsObjectRegistry
-    MergeRequestDiffRegistry
-    PackageFileRegistry
-    PagesDeploymentRegistry
-    PipelineArtifactRegistry
-    ProjectWikiRepositoryRegistry
-    SnippetRepositoryRegistry
-    TerraformStateVersionRegistry
-    UploadRegistry
-    ```
-
-  - Find registry records that are missing on the primary site:
-
-    ```ruby
-    Geo::PackageFileRegistry.where(last_sync_failure: 'The file is missing on the Geo primary site')
-    ```
-
-  - Resync a package file, synchronously, given an ID:
-
-    ```ruby
-    model_record = Packages::PackageFile.find(id)
-    model_record.replicator.sync
-    ```
-
-  - Resync a package file, synchronously, given a registry ID:
-
-    ```ruby
-    registry = Geo::PackageFileRegistry.find(registry_id)
-    registry.replicator.sync
-    ```
-
-  - Resync a package file, asynchronously, given a registry ID.
-    Since GitLab 16.2, a component can be asynchronously replicated as follows:
-
-    ```ruby
-    registry = Geo::PackageFileRegistry.find(registry_id)
-    registry.replicator.enqueue_sync
-    ```
-
-  - Reverify a package file, asynchronously, given a registry ID.
-    Since GitLab 16.2, a component can be asynchronously reverified as follows:
-
-    ```ruby
-    registry = Geo::PackageFileRegistry.find(registry_id)
-    registry.replicator.verify_async
-    ```
-
-- **For Repository types** (using the `SnippetRepository` component as an example)
-
-  - Resync a snippet repository, synchronously, given an ID:
-
-    ```ruby
-    model_record = Geo::SnippetRepositoryRegistry.find(id)
-    model_record.replicator.sync
-    ```
-
-  - Resync a snippet repository, synchronously, given a registry ID
-
-    ```ruby
-    registry = Geo::SnippetRepositoryRegistry.find(registry_id)
-    registry.replicator.sync
-    ```
-
-  - Resync a snippet repository, asynchronously, given a registry ID.

-
