Retro-Sync: Hurrian Hymn h.6 — 71-Shard NFT Collection

The world's oldest surviving notated music (~1400 BC, Ugarit) encoded as a multi-layered NFT collection with ZK proofs and steganographic embedding.

Collection

71 DA51 CBOR shards — one for each integer 1..71 (the crown prime). 20 generator shards (primes ≤ 71) carry the SSP interval structure. 51 derived shards (composites) carry content determined by prime factorization.

Layer	Content	Format
Source	Babylonian notation, interval mapping	text
Notation	LilyPond score (West 1994)	.ly
Artifacts	MIDI, PDF score, WAV audio	base64 in CBOR
Witnesses	Compilation chain (5 steps)	JSON
Eigenspace	Earth/Spoke/Hub decomposition	numeric
Metadata	Tablet, scribe, tuning, deity	structured
References	Wikipedia, scholarly, LilyPond docs	URLs
YouTube	Private audio comparison sources	URLs
Pipeline	SOP, erdfa CFT, boustrophedon, Cl(15)	text
ZK Proof	Groth16/BN254, MiMC Merkle tree	JSON

Decoding

Each shard is a DA51-tagged CBOR envelope:

Bytes 0-1: 0xDA 0x51 (magic)
Bytes 2-9: SHA-256 prefix (CID stub)
Bytes 10+: CBOR payload

import cbor2, json
with open("nft71/02.cbor", "rb") as f:
    raw = f.read()
    magic = raw[:2]  # b'\xda\x51'
    cid = raw[2:10].hex()
    payload = cbor2.loads(raw[10:])
    print(json.dumps(payload, indent=2))

ZK Verification

The Groth16 proof verifies:

Prover knows all 71 shard hashes
All form a valid MiMC Merkle tree
Eigenspace commitment matches (100% Earth)
Crown shard (p71) is unique
