Sub-claim "USDC can settle transactions instantly on the blockchain.": 100% covered by S1

The gathered sources provide clear and direct evidence for all sub-claims. Source S1 explicitly states that USDC settles peer-to-peer onchain in seconds, removes delays, and provides final settlement. This covers the first two claims about instant settlement being a feature. The explanation of how instant settlement removes delays and enables machine-to-machine commerce without counterparty risk (S1) supports the claim that this is relevant to understanding stablecoins. The description of USDC settling in seconds (S1) as a specific capability distinguishes it from traditional payment networks, which implicitly differentiates it within the stablecoin category, though explicit comparison to other stablecoins is not detailed. All claims are covered with evidence from at least one source.
All sub-claims already well-covered (sufficiency passed with 0 gaps) — skipping re-evaluation to save latency.

Final coverage assessment — All sub-claims are fully covered by S1, which explicitly states that USDC settles peer-to-peer onchain in seconds, making final and programmable settlement a key feature. S2 is unrelated (about Coinbase Cloud developer tools) and does not affect coverage of the stablecoin-specific claims.
