pub fn issue_settled(
checkpoint: PicPcaPayload,
realm: &dyn ArtifactSigner,
ctx: &SettlementContext,
) -> Result<SettledIssue, ContinuityError>Expand description
Signs a checkpoint into the settled artifact chain:
PIC PCA COSE → settled PIC Continuity COSE (transitions = null) →
settled PIC Token JWT. This is the initialization path (checkpoint 0,
e.g. after an OAuth-to-PIC exchange) and the tail of every settlement.
