#     - X39_UNIFIED_DOSSIER_FINAL_2026-06-02.pdf
#     - X39_CERTIFICADO_OFICIAL.pdf
#     - X39MATRIX_Dossier_Soberano_Marruecos.pdf
#
#  Dependencies (auto-checked):
#     - bash 4+, curl, python3
#     - Optional: python3-ecdsa (for §VI deep signature verification)
#
#  Public infrastructure queried:
#     - blockstream.info  (Bitcoin)
#     - arbitrum-one.publicnode.com  (Arbitrum One)
#     - api.mainnet-beta.solana.com  (Solana)
#     - ic-api.internetcomputer.org  (ICP)
