* Remove the automations module
Drops the visual workflow builder end to end: actions, node runners,
commands, jobs, models, observers, policy, resources, requests, routes,
broadcast channel, scheduler entries, Horizon supervisor, Vue pages and
components, canvas undo/redo history, CodeEditor, translations, factories
and tests.
A new migration rewrites posts.created_via = 'automation' to 'web' and
drops the five automation tables. The CreatedVia::Automation enum case is
removed. The 2026-08-21 social-account identity migration now skips its
automation node repointing when the automations table no longer exists,
so it stays re-runnable after the drop.
Orphaned dependencies removed: simplepie/simplepie, @vue-flow/*,
codemirror and @codemirror/*.
* Drop the orphaned common.beta translation key
* Remove automation leftovers: ResolvableUrl rule, feed fixtures, useShortcut, nav badge
* Drop the unused chart wrapper and @unovis packages
* Address review: keep the shipped migration untouched, drop the dead previewOnly chain
- Restore 2026_08_21 migration to exactly what production ran; the
rehearsal test now recreates the automations table it expects instead.
- Mark the drop migration's down() irreversible like its siblings.
- Simplify DropAutomationTablesMigrationTest to the sibling shape.
- Remove previewOnly / aiGenerateVariants: the only caller that set the
prop was the deleted automation Generate node.
- Run pint over lang/*/common.php after the beta key removal.
* Exercise the drop migration against the real automation tables and their FKs
* Drop DuplicateIdentityRehearsalTest: it re-ran a frozen migration that reads the removed automations table
