We report a complete structural analysis of the Phaistos Disc (c. 1700 BCE), establishing six principal results through positional distribution analysis and permutation testing on the complete Evans transcription (61 groups, 241 tokens, 45 signs). Sign 02 (PLUMED HEAD) is locked to initial position at 19/19 (100%), p = 4.6 × 10⁻¹² (1 in 217 billion), confirmed by permutation testing (p < 0.0001). The compound bigram 02+12 appears at 13.0x above chance as a stable header complex in 21% of groups. Seven formulaic sequences repeat at non-random rates (25% of groups involved, p < 0.0001). Sides A and B show different dominant header signs, indicating distinct document categories. A tabular structure with three regularly-spaced section dividers and duplicate entry-footer pairs is identified on Side A. A five-layer positional grammar is established covering 77% of groups. A complete structural map classifies the disc as a two-part structured register — not running prose, not poetry, not a continuous text. The structural layer is fully characterised without a bilingual inscription, phonetic knowledge, or language identification; only the content layer remains open. Full methodology withheld pending peer-reviewed publication. SHA-256 hash of the full manuscript included for verification.
