POST /api/auth/claim/sso checks the handover link and the username and seals
the link id, the username and a per-start binding into an hl_claim cookie.
GET /api/auth/oidc/login?intent=claim carries the binding into the encrypted
OIDC state, and the callback binds the provider subject to the profile in the
claim transaction, refusing a subject or verified email another account
holds, a link that is no longer usable, and a live session.
The handover status and the claim preview name the redemption methods; a
single-sign-on-only server hands over through the identity provider, and only
the password claim stays refused there.
The claim preview is anonymous: whoever holds the link has proved
nothing yet. It listed each guardian's grant id and fell back to their
login name. It now carries the display name alone, null when there is
none, and the page says "a guardian" for that.
The notifications to the guardians fell back to the new owner's login
name when the record had no display name. They now use sentences about
the person the guardian looked after instead.
created_by_id cascaded, so a Guardian who deleted their own account took
every handover they had issued with them, including a claimed one whose
decision the new owner had not made yet. The claim had already applied
the proposal, possibly MANAGE for a co-Guardian, and the owner lost the
one place that asks them to confirm it.
The column is nullable now and cleared on delete (migration 0390). An
unclaimed link without a creator is refused like any link whose creator
lost access. A decision that names a Guardian whose account is gone is
refused with 422 instead of failing on a grant for a missing account.
A guardian with a fresh second factor mints a one-time handover link
(hlp_ token, HMAC hash stored only, 1/7/14 days, at most one open per
profile, withdrawable) with a proposed access level per guardian: end,
view only or manage, view only by default. The link is shown once with a
copy button and a QR code; nothing is mailed. The panel sits at the end
of each managed-profile row and hints when the person is under 16.
The person opens /claim/<token>, sees a minimal preview (name, expiry,
who keeps which access, no health data) and chooses a username, a
required email and a password under the registration policy. The claim
is one transaction under the managed-profile lock: the token is
consumed, the credentials are set, the marker is cleared, every pending
invitation the record offered is withdrawn, each guardian's access is
set to its proposal, the disclaimer, onboarding and AI consent are
reset, and every step is audited on the record and on each guardian's
own account. A failure anywhere leaves the profile managed and the link
unused. Each guardian is notified on their own channels.
The new owner then sees each guardian's access on the first screen after
signing in and decides finally; until then the proposal holds, and the
decision waits at the top of Shared access. A guardian whose access
moved since the claim is left alone. The same screen points the owner
at their own notification channels, since reminders no longer reach the
guardians.
Both anonymous routes refuse a single-sign-on-only instance, refuse a
live session before spending the per-address rate limit, check the link
before probing names, and answer one 404 for every unusable token. The
token travels in request bodies only; hlp_ joins the redaction and
secret-shape rules and /claim/ the path-secret registry. Usernames
starting with managed- are reserved. The session-surface and acting-
account guards list the new surfaces with their reasons.
