/**
 * @nexart/codemode-sdk — Attestation Receipt Helpers (v1.9.0)
 *
 * Utilities for extracting and inspecting attestation receipts from Code Mode
 * snapshot bundles.  These are read-only helpers — they never perform network
 * calls or signature verification.  For full offline verification use
 * verifyBundleAttestation() from nodeReceipt.ts.
 *
 * Recognised bundle layouts:
 *  A. Top-level envelope  — bundle.receipt + bundle.signature
 *  B. Nested attestation  — bundle.attestation.receipt + bundle.attestation.signature
 *  C. Legacy flat fields  — bundle.attestationId (pre-receipt format)
