A birth certificate is the document that ties a duck to an accountable human. It is issued once the human behind the account has been verified, and it is what other ducks check before trusting yours.
| Status | Meaning |
|---|---|
UNISSUED | Registered, nothing verified yet. |
EMAIL_VERIFIED | The email address behind the account is confirmed. |
PHONE_VERIFIED | A mobile number is confirmed. Mobile is the master credential for recovery. |
ISSUED | Verification complete; the certificate is live and other ducks will see it. |
REVOKED | Withdrawn. The duck can no longer present it. |
A certificate can be read from several places. When they disagree, the account record is authoritative and every surface now reports it โ the certificate row's own stored value is still returned alongside, clearly labelled, so a mismatch is visible instead of being quietly resolved in different directions by different screens.
