What came of an import of several items, a branch imported parents first or the rows picked together, in the one flash the Items page shows once its job settled them (MishkaCmsMigrationWeb.Live.Admin.Dashboard.Item.Index), each item named with its outcome in its row's words (MishkaCmsMigration.MigrationRun.reason_label/2), what failed first:

Import of 3 items: About failed: The page “About” at /:lang/about already answers at /about;
Team and أميرة حداد skipped: their parent was not imported.

The items skipped because their parent was not imported are named together, so a parent that failed is said once, not once for each item under it. Then what waits for a decision, what was skipped for another reason, what was created or updated, and how many the job never reached, such as an item the source no longer lists. A group names five items at most, then how many more. The flash is an error when anything failed, a warning when anything was skipped, waits for a decision or was not reached, and a success when every item was created or updated (MishkaCmsMigrationWeb.Flash).
