Oracle price deviation >X% from secondary

USDD (Decentralized USD)'s assessment for RD-F-099 — scored gray on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Oracle price deviation signal is applicable to the TRON-side CDP (TRX USD price used for collateral ratio enforcement). The oracle mechanism for TRX pricing is not publicly documented — data cache oracle: null; oracle_feeds: []. TRON-side on-chain reads blocked (Tronscan 403). Ethereum-side PSM uses 1:1 USDC/USDT swap design (no oracle price feed needed by design). Cannot assess oracle deviation posture without resolving the TRON CDP oracle source address.
