Verdict: APPROVE
Risk: LOW
Summary: The PR is a narrow Ethereum oracle listing update that adds Supra pull-oracle listings for the existing !offer:supra canonical offer on hoodi and sepolia. The touched CSV keeps its 17-column schema, the new listing rows are well formed, the canonical Supra offer and provider resolve, required chain logo files exist, and the official Supra pull-oracle networks page lists Ethereum Hoodi Testnet and Ethereum Sepolia Testnet. Validation and current-head link-check both passed; the link-check bot summary reports 0 errors/timeouts.
Findings: None.
Confidence: HIGH
