PTVS Forensic Audit Report — Sample | PTVS-2026-ES-0412

Layer 0 — Physical Reality (L0-PR)

Court-Admissible · eIDAS 2.0 QES Signed · On-Chain Anchored

91

GRADE AAA

Asset Approved for Institutional Tokenization · Circuit Breaker Threshold: <70

Structural (E)

88

Weight: 40%

Environmental (M)

92

Weight: 20%

Documentary (D)

90

Weight: 10%

Formula: PTVS Score = (E × 0.40) + (L × 0.30) + (M × 0.20) + (D × 0.10) = (88×0.40) + (95×0.30) + (92×0.20) + (90×0.10) = 35.2 + 28.5 + 18.4 + 9.0 = 91.1 → 91
