ERC-4626 virtual-share offset (OZ ≥4.9)

Spiko's assessment for RD-F-074 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

USTBL/EUTBL are not ERC-4626 vaults. They are ERC-20 tokens (and Stellar/Starknet equivalents) representing registered UCITS fund units. NAV accounting is managed off-chain by the fund administrator; no share-inflation attack surface exists. Lending-vault-specific factor per taxonomy PD-024.
