Oracle price deviation >X% from secondary

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

Evidence summary #

v1-deferred. Unique oracle architecture: Polymarket uses UMA Optimistic Oracle for truth-attestation (not price deviation). Chainlink feeds present on Polygon (USDC/USD at 0xfE4A8cc5b5B2366C1B58Bea3858e81843581b2F7) but consumer contracts not confirmed as direct Polymarket dependencies. Signal architecture requires reframing for prediction market context. UMA DVM manipulation (whale attack March 2025) is a governance-layer event, not price-deviation. Not assessable via standard RD-F-099 detection rule.
