Deleting an account, a guardian deleting a managed profile, and "Delete
all data" were final the moment they were confirmed: the account row
cascaded into every table and every stored copy, and the off-host objects
were purged in the same breath. Nothing short of rolling the whole
instance back could return one account.
ACCOUNT_DELETION_GRACE_DAYS (14 by default, at most 30, 0 erases at once
as before) now sets a window:
- Account and managed-profile deletion lock the account (migration 0488:
deletion_requested_at, deletion_purge_at, deletion_requested_by_id).
Every session, refresh token, API token, connector, share link and
step-up elevation is revoked in the same transaction, and the record,
its stored copies and its off-host objects are left as they are.
- Sign-in is refused with 403 auth.account.deletion_pending and the
erasure date, after the credential was proved and before a second
factor is asked for. The session and Bearer resolvers and the acting-
account resolver refuse a pending account too, so a credential minted
in the moment before the lock is useless.
- POST /api/admin/users/{id}/undo-deletion (cookie-only, audit-logged)
clears the lock. The admin users list reports the pending state.
- The hourly account-deletion-purge job erases accounts whose window has
ended, exactly as the immediate deletion did, with the off-host purge
request committed alongside. The Guardian invariant is decided again;
a refused erasure stays pending and is reported.
- A wipe first stores the whole record as a PRE_WIPE_<ms> copy through
the writer the weekly copy uses, keeps it out of the wipe, and holds
its off-host purge back with a new not_before on the request. The
ordinary restore brings the record back; restoring that copy withdraws
the held purge. The purge job deletes the copy when its window ends.
Background work skips accounts pending deletion through one shared
predicate (src/lib/account-deletion/active-account.ts): every reminder,
digest, Coach, sync, backfill, rollup, score and backup enumeration
filters with it, and account-deletion-enumeration-guard.test.ts fails on
a query in background work that neither filters nor says why it need
not. Notification delivery and the AI capability loader refuse a pending
account as chokepoints behind it, and the Withings, WHOOP and Telegram
webhooks and the notification quick actions ignore one.
The privacy summary publishes the window. Two pieces of the reminder tick
and the off-host pass moved into modules of their own to keep the files
inside their size ratchet.
A data wipe during the nightly upload could leave the pre-wipe copy in
the bucket: the purge the wipe started removed its request at once, and
the upload still in flight checked that request after finishing and found
nothing. A wipe's request now stays until a nightly run has walked the
account since the wipe. Until then each purge removes only the copies
dated up to the wipe's day, so the copy of what the account holds after
the wipe stays, and the admin card no longer counts the waiting request
as copies still in the bucket.
Deleting an account, deleting a managed profile, "Delete all data" and the
admin wipe now write an off-host deletion request in the same transaction
as the deletion. A new job (offhost-backup-purge, kicked straight away and
run nightly as a backstop) lists the bucket once, deletes every
<date>/user-<id>.json.enc object of each pending account and removes the
request only when nothing of the account is left. A refused delete keeps
the request with the bucket's answer and is retried; the off-host card
shows how many deletions are outstanding and why. A copy the nightly run
was writing while the account was deleted is taken back after the upload.
The off-host card also reads the bucket's lifecycle rule and says plainly
when there is none (every nightly copy kept forever) or when the
credential may not read it.
Every stored backup now records the key ids its content was written
under, and every off-host upload records the same per key. The admin
encryption view lists, per key, the stored copies that need it with the
oldest date, and when the last off-host copy needing it expires. The
"safe to drop" badge now requires that no backup still needs a retired
key, instead of only that every row was rotated.
Migration 0358 adds data_backups.inner_key_ids, the key-use table and the
deletion requests.
