createX402Server injects into every
route regardless of route-specific metadata.
Both gas-sponsoring entries are present. Their presence signals to the x402
EVM client that the CDP Facilitator can cover Permit2 gas costs; the client
only activates the path when requirements.extra.assetTransferMethod is
"permit2", so the declarations are harmless for EIP-3009 and Solana routes.
Bazaar is NOT in this set — it is injected separately because it requires
per-route metadata (HTTP method, path template) to build its declaration.
