There was no way for an admin to remove someone else's account; the
users list only offered the undo for a deletion the account itself or a
Guardian had asked for.
DELETE /api/admin/users/{id} takes the account's own deletion path,
now shared as requestAccountDeletion: with a grace window the account
is locked at once (credentials revoked, record untouched) and erased by
the purge job when the window ends, and the existing undo gives it back
until then; with ACCOUNT_DELETION_GRACE_DAYS=0 it is erased in the
request. The route is cookie-only behind requireAdmin and the
recent-proof gate, takes the typed DELETE_ACCOUNT confirmation, and
refuses the caller's own account, a managed profile (its Guardians
delete it), an account already pending deletion, the last admin who
can sign in and the last Guardian of a managed profile, the last three
decided under their locks inside the transaction. Both the admin and
the account get an audit row.
The users list says who asked for a pending deletion, now including an
admin, and flags managed profiles. Each other account's row carries a
delete button whose confirmation names the purge date, or says the
erasure is immediate when the server keeps no window.
The floor was described on the one route that cannot reach it and left unsaid
on the two that answer it every time: withdrawing the last Guardian grant and
renouncing it both raise `managed_profile.guardian.required`, and both
published only 'that access had already ended'. Both 409s now name their two
codes, and the annotation on the removal route enumerates all four emitters
rather than three.
A guard closes the class rather than the instance: every route module that
raises the refusal must publish it on its own operation, with the emitters
discovered from the sources.
The freeze guard gains its containment leg — a module becomes delegable by
review, not by discovery, so every file contributing a fenced verb has to be a
member of one of the surface guard's frozen allowlists.
- publish the roster's entry from the invitation and `{ grantId, revokedAt }`
from the removal, instead of the account-grant row Prisma returned
- drop the invitation's self refusal: it named a code no request can elicit,
because a Guardian grant's grantor is the profile and never the caller
- name the duplicate grant error rather than catching every grant refusal into
a sentence that would be wrong for any other one
- keep the rate limit and the unknown-identifier 404 free of an error code,
as their siblings elsewhere are, and say why at the call site
