Creates or returns an open identity verification for a Person, Account, or Stakeholder. Select X-Wingspan-Account to verify an active Stakeholder using its Account-supplied Individual identity. Create one verification for each human, then resume each to obtain its separate SDK token. A representative with multiple roles uses one Stakeholder verification. No Wingspan Person login is required for this flow. For an Account with no principal, Account convenience requests resolve to the selected representative Stakeholder when available and reuse the same open verification. Unmapped legacy Business representatives retain an Account subject. An Account with a principal verifies its principal Person. Callers with Account scope can read that verification, but only that Person can create or resume it; anyone else gets 403. Existing Individual/Person aliases retain their canonical Person subject. Reads and resume of Account-owned verifications require Account scope. The identity record and vault are bound at creation. After they are replaced, resuming the earlier verification returns 409 and a new create opens a verification for the replacement identity. Private Person-owned identities require Person authorization. The current bridge always runs the existing enhanced embedded identity flow; tier selection, additional checks, metadata, notification controls, and inline monitoring are not accepted until native V3 identity verification flows are available. Replays with the same Idempotency-Key and subject return the original verification; reusing the key with a different subject returns 409.
