- 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
- add GET /api/managed-profiles/{id}/guardians, cookie-only, refusing
anybody who is not an active guardian of that profile with the same 404
an unknown id gets
- disclose the grant id, the party block already shared between grant
parties, the derived state and the two timestamps, and nothing else
- publish the route in the OpenAPI contract
- Exclude and erase egress claims with recipient-side lookup support\n- Serialize data wipes with managed-profile Guardian authorization\n- Cover last-Guardian and queued-claim wipe races
