ECC Protocol V1 is a cryptographically verifiable experimental protocol specification released as a public integrity-locked document. This record provides a permanent archival reference for the original protocol specification and associated verification artifacts. The files included in this record are intended to allow independent verification that the published documents have not been altered since the time of release. The protocol document is archived with a DOI to provide a stable academic citation and long-term preservation. Files included in this record: ECC_PROTOCOL_V1_LOCKED.pdfHuman-readable publication version of the protocol specification. ECC_PROTOCOL_V1_LOCKED.txtCanonical text version used for cryptographic integrity verification. SHA-256 integrity verification values: TXT SHA-2565b56f261376fee8e846474511c24f7ae02a99877a6b78aaf965855ecd4829492 PDF SHA-2565C9BEB18A9C474E12689165F3B0AC44958994A5B221966724BC79C4B6A97502A These hashes allow independent researchers to verify the integrity of the archived files using standard cryptographic hashing tools. Verification example (PowerShell): Get-FileHash ECC_PROTOCOL_V1_LOCKED.pdf -Algorithm SHA256 Get-FileHash ECC_PROTOCOL_V1_LOCKED.txt -Algorithm SHA256 If the computed values match the hashes listed above, the files are confirmed to be identical to the originally archived publication. This release serves as a timestamped archival reference for ECC Protocol V1 and is intended to support transparency, reproducibility, and independent verification of the protocol specification.
