Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • cedulon_auditAudit the receipt chainread-only

    Reconcile the in-process receipt chain and checkpoint against the rail extract: this server's own ledger, or a signed extract you present. Returns audit: balanced or findings, names the account, rail and window it was computed over (scope) when an extract declared one, and counts the class every receipt and row landed in (counts).

  • cedulon_export_ledgerExport the ledgerread-only

    Export receipts, checkpoint, and rail extract in the same JSON shape as npm run demo:export, with the findings, guarantee and counts of the audit over this server's own ledger.

  • cedulon_spendSpend on the mock rail

    Policy-gated spend on the mock rail. Allow returns a signed COSE receipt JSON. Deny returns the fail-closed reason.

  • cedulon_statusServer statusread-only

    Server version, policy summary, receipt count, and chain head hash.

  • cedulon_verify_receiptVerify a spend receiptread-only

    Verify a spend receipt COSE_Sign1 (and payee countersignature when present). Supply expectIssuerKeyPem to check it against a key you already hold; without one the receipt is only checked against the key it carries, which any key satisfies.
