  serialisation, and signature verification (#420)

  binding (#421)

  proof-of-field-revelation (#422)
• Certificate utilities: validate_certificates and get_verifiable_certificates
  helpers (#427, #428)
• Peer protocol: certificateRequest/certificateResponse message handling,
  callback registration, and last_interacted_peer (#430, #431)
• High-level peer session API: Peer#to_peer and Peer#get_authenticated_session
  for reusable authenticated sessions (#433)

Fixed

• Auth handshake now uses shallow key conversion to avoid corrupting nested
  message payloads
• Certificate classes hardened against edge cases from code review
• Certifier allowlist enforced in process_certificate_response
• Flaky validate_certificates_spec fixed (missing require 'base64')

Changed

• GetVerifiableCertificates bug warning note removed (underlying bug now
  fixed in bsv-wallet)
• Peer protocol internals refactored: PairedTransport helper, deduplicated
  high-level API, hardened message processing
