Evidence summary #

T-09 v1 phase-2 deferred; tier-B. USYC NAV oracle at 0x74f2199AEb743f68f05943e5715A33EaF2b61f53 (Ethereum) provides on-chain fund NAV (~$1.065/token). No secondary oracle for comparison has been mapped. USYC oracle tracks fund NAV, not a spot price - standard oracle-deviation signal applicability differs from lending-protocol use case. Phase-2 secondary oracle mapping work required. No deviation observed from public OSINT.
