AP2 x402 Cart Correlation

Correlates a built AP2 CartMandate (cart_root, cart_items, merchant) against an x402_spend_evidence pack: does the cart total (sum of quantity*unit_price per currency) match the x402 authorization's value, does the CartMandate's merchant map to the authorization's recipient address, and does the CartMandate's own hash-chain independently re-verify against the supplied cart_items (never trusted as a self-reported flag). Output vocabulary is CORRELATION_STATUS (CORRELATED / NOT_CORRELATED / INDETERMINATE) -- this is a plausibility check over two independently-produced artifacts, never a cryptographic binding. Google has not shipped an AP2-compatible x402 extension; no field or code path here implies one exists. Zero network calls; never a facilitator, proxy, gateway, or settlement relay.
