Execute Cancellation
Finalize an approved cancellation endorsement. This step uses the saved approval; it does not create a replacement approval or reset notice work. For an intent-backed approval, PAS requires confirmed notice-document readiness and the required physical-print chain’s accepted queue handoff before finalization. If that readiness is missing or the continuation requires review, the API returns HTTP 409 with reason_code: cancellation_notice_continuation_review, approval_saved: true, and notice_continuation containing id, phase, and its specific reason_code. The response carries the immutable cancellation ID, current submission status, actual stored ISO dates and cancellation_notice metadata. Execution remains blocked; the saved approval is not rolled back. Keep that receipt and contact Cover Whale for review or safe recovery. Do not reapprove the cancellation or repeat an uncertain external handoff. Existing Cancellation Guard refusals may also return 409 with their own reason code. PDF readiness alone does not satisfy a required print-chain handoff. When no physical print jobs were created, actual PDF generation completes that handoff without claiming print delivery. Document readiness and initial queue acceptance do not prove filing acceptance, print-provider delivery, or exactly-once delivery. See Approve Cancellation.
