Oracle price deviation >X% from secondary

Spiko's assessment for RD-F-099 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Spiko's oracle publishes NAV (net asset value of UCITS T-bill fund), an off-chain-computed price with no secondary on-chain feed for deviation comparison. The signal presupposes a live market price on a secondary venue; T-bill fund shares have no such secondary on-chain market. Structural mismatch: applicable to DeFi AMM/lending oracle deviation, not to off-chain NAV provision.
