on_purge_application only rmtree'd the storage dir for source=='upload'
apps. A purged git/template app left its clone under APPS_DIR behind, so
the name stayed blocked ('App directory already exists') forever while
the Recycle Bin showed nothing to explain it.
Now any non-manual app whose root_path lives under APPS_DIR is reclaimed
at purge; manual apps keep the operator-owned-directory guard.
The user-delete guard 79a78c3c added queried Application straight from
the controller, tripping the API controller boundary ratchet. The count
now lives in application_restore.applications_owned_by — the module
that owns Application's recycle-bin semantics and documents why
tombstoned rows block too.

Plan 70. Domain went through this and TEN read paths were wrong, four with
effects outside the panel. Application has 211 call sites across 68 files and
drives more -- container lifecycles, nginx, backups, registry pulls, the OS
crontab -- so it was audited in full first (docs/plans/70_...md). 180 sites are
now query_active(); the 35 left unfiltered are each commented in place.
**The delete / purge split is what makes the tombstone honest.** delete_app used
to run compose_down(volumes=True) and rmtree(). Keeping a tombstone AND doing
that would put a Restore button next to a row whose data the delete had already
destroyed -- the one promise a recycle bin cannot break. So:
DELETE containers down (VOLUMES KEPT), vhost removed, firewall closed,
cron suspended, row tombstoned. All reversible.
RESTORE vhost rewritten, firewall reopened, cron resumed. Containers left
STOPPED -- "put it back" must not silently start processes or open
ports, the same reasoning that stops domain restore re-issuing certs.
PURGE volumes removed, uploaded source deleted, cron detached.
register() gained on_purge for that, wired into BOTH purge paths. And
purge_expired had NO scheduler -- fine when a tombstone was just a row, not fine
when it holds data volumes and a source tree, so a daily builtin job now runs
it. Without that, "kept until purge" would have meant kept forever and delete
would have quietly stopped reclaiming disk.
A side effect worth naming: the old _remove_data_flag protection for database
engines is now the DEFAULT for every app, and the flag is carried into
?purge=true so an explicit skip-the-bin delete still honours it.
**Cron was the blocker with no mechanical answer.** before_delete never fires on
a soft delete, and clear_application is LOSSY -- it nulls the association
without recording it, so nothing could put it back. suspend_for_application
instead disables only the jobs that were CURRENTLY ENABLED and stamps each
suspended_by_app; resume re-enables exactly those. That flag is the whole point:
without it a restore switches back on jobs the user deliberately turned off.
clear_application survives as purge-only, where lossiness is correct.
**The indirect reach (audit 3.1) is the class that grep cannot find.**
ContainerSleepPolicy, BackupPolicy, DeploymentJob and WafPolicy are enumerated
on a SCHEDULE and resolve application_id afterwards, so they never appear in a
search for Application.query. Left alone, a tombstoned app's sleep policy is
swept forever and wake_app restarts the containers the delete tore down. Those
loops test Application.deleted_ids().
Deliberately NOT scoped: reservation checks (port, name, directory) -- a
tombstone must keep holding those or a new app takes them and the restore is
refused; api/git.py's webhook VISIBILITY gate, which falls through to
"panel-wide visible" so hiding a tombstone would WIDEN access; and cron
attribution, which only labels a row.
Verified: 15 new tests, the migration replayed on a fresh DB (a tombstone frees
its private_slug, two live rows still collide), and a full delete -> restore
round trip. The 20 remaining full-suite failures are the known
serverkit-wordpress-not-installed class and are identical on a clean tree.
Two traps caught by testing, both recorded in the plan: a bad import made the
ENTIRE purge cleanup silently no-op while purge() still reported success
(_run_purge_hook swallows by design, so assert on the warning, not just ok), and
private_slug had to lose unique=True at the MODEL level or a models-built
database burns the slug regardless of the migration.
