Re-evaluate

Sub-claim "X402 uses USDC finality to reduce settlement times in cross-…": 40% covered by S2, S3 — S2 discusses USDC instant settlement but not x402. S3 discusses x402 settlement latency but not USDC. No source directly connects USDC finality to x402 settlement time reduction.

Re-evaluate

Sub-claim "USDC finality ensures data consistency across chains in plan…": 0% covered — No gathered source mentions plant genomics or data consistency across chains.

Re-evaluate

Sub-claim "X402 integrates USDC finality to enable real-time replicatio…": 0% covered — No gathered source mentions genomic data or real-time replication.

Re-evaluate

All three sub-claims have low coverage (<0.5). The remaining budget ($0.02) can afford several cheap sources. Recommended sources are relevant to USDC, x402, and cross-chain replication, potentially filling gaps. Plant genomics is not covered by any skipped source, but these may provide general cross-chain replication insights.
