The user-detail console gains a Deletion & retention panel: last login (time + IP),
the tombstone (deleted-at + retained real name), and the retention journal (the legal
dossier of detached credentials). A Delete-user action runs the same deletion
orchestration as the in-app flow (mirrors the email-erase pattern). Store readers
RetainedIdentities + DeletionInfo back the view; integration test covers them.
Daily background reaper purges the deletion dossier past its two-year TTL: every
retained_identities row by detached_at (covering unlink/change on live accounts too),
and — for accounts tombstoned before the cutoff — the retained feedback thread plus the
dossier PII (deleted_display_name, last_login_ip). Chat is kept (a shared game artifact)
and the tombstone row stays. Started from main next to the guest reaper. Integration
test covers the cutoff boundary and the deleted-account feedback/PII purge.
The profile GET (fetched once per cold app-load by the SPA) stamps accounts
.last_login_at/.last_login_ip, throttled to at most once per hour per account
(best-effort, never blocks the read). IP from the gateway-forwarded X-Forwarded-For.
Feeds the account-deletion dossier. Integration test covers the throttle.
On unlink (RemoveIdentity, reason=unlink) and email change (replaceEmailIdentity,
reason=change) write the outgoing credential to retained_identities before removing
the live identities row — so the legal dossier survives while the (kind, external_id)
frees for reuse. Same transaction, so the dossier and live state cannot diverge.
Integration tests cover both reasons.
