The migration's admin page: a card for each installed source (MishkaCmsMigration.Source.all/0), and under them the runs of the admin's site, every site's for a master, as a Gervaz table (see MishkaCmsMigration.MigrationRun for its columns and row actions). The table follows the runs' PubSub notifications, which this page hands on to it.

A card's New import opens the run's Gervaz form for that source in a modal: the page sends the form defaults: %{source: id}, so its Connection draws the keys that source asks for (MishkaCmsMigration.Source.form_fields/1), its secret as a masked password input, or, for a source that reads a file (MishkaCmsMigration.Source.file?/1) such as the WordPress export file, its Export file upload instead. Another source's New import starts the form over for it; the same source's opens it as the admin left it, answers and step kept, until a run starts or the admin presses Start over. The window is Gervaz's wizard of four steps (MishkaCmsMigrationWeb.Live.Admin.Dashboard.ImportSteps): where from, what to bring, languages, and a review in plain words. Its Start the dry run, which reads "Checking the source…" while it runs, creates the run once the source answers, or reads the file, and starts the run's dry run at once, which writes nothing to the site; a run the site cannot start it for, because another run of the site is running, stays Connected and a warning says why. The modal then closes and the run shows in the table. A refusal on an earlier step returns the window there and the form's error flash names the step ({:put_flash, kind, message}).

Every flash says what it means (MishkaCmsMigrationWeb.Flash): Dry run started and Import started are info, Run cancelled is a success, a step the run refuses is info, and a run that is not there is an error.

A run's row

Dry run, Run again, Import and Cancel reach this page as {:row_action, "dry_run" | "import" | "cancel", %{"id" => id}}. The page reads the run as the table does, a master's through :master_get on any site, a site admin's on their own site alone, and runs MishkaCmsMigration.start_dry_run/2, MishkaCmsMigration.start_import/2 or MishkaCmsMigration.cancel_run/2 as the signed-in admin, on the run's site. It says so in a flash; a run it cannot read, such as another site's id sent by hand, or a step the run refuses, such as a second dry run while one of the site's runs is running, is said in Gervaz's words for a failed row action (MishkaGervaz.Errors.format_flash_message/2), and nothing changes.

Items, on a row, is a link to the run's Items page (MishkaCmsMigrationWeb.Live.Admin.Dashboard.Item.Index).

An expanded row ({:expand_row, id}) shows the run, read the same way, as MishkaCmsMigrationWeb.Live.Admin.Dashboard.Home.RunDetails draws it: where it is and when it got there, the warning for users an import created (PasswordNotice), what its last report found kind by kind and its latest items, each with links to its CMS record, how far a running job is, why a failed run stopped, and what its source said of itself and the admin chose. The page keeps which row it last expanded and draws it again on each of that run's notifications, so a dry run moving on, or finishing, shows in it without a reload.

Logs

Logs, beside the table's count, is the core's activity feed (MishkaCmsCoreWeb.Live.Admin.Components.ActivityFeed, as the runtime pages show theirs) over the runs' log alone (MishkaCmsMigration.Activity): each step of a run, newest first, in the sentence the bell says, who took it and on which site. It reads the latest entries the first time it opens and adds each new one as its broadcast arrives.

Who may open it is the sidebar's declaration (MishkaCmsMigrationWeb.SidebarMenu), which MishkaCmsCore.Sidebar.PageGuard reads on every mount.
