Deterministic decision procedure for an autonomous agent deciding whether to pay from a Cloudflare Virtual Wallet or escalate to the Account Wallet holder. Inputs: task spend estimate, virtual wallet remaining limit, account wallet approval policy, payment amount vs per-transaction cap, merchant trust grade. Procedure: (1) classify the payment as routine (under virtual limit, known merchant, deterministic deliverable) and pay autonomously, (2) classify as boundary (over 80% of remaining virtual limit, new merchant, first-time rail, or refund-sensitive) and escalate for human authorization, (3) verify the virtual wallet is actually bound to the account wallet by checking the delegation record and issuer signature before trusting it as a payment source, (4) reconcile the virtual wallet ledger against the account wallet after settlement, (5) freeze the virtual wallet when spend anomalies exceed thresholds. Failure modes: unbound virtual wallet impersonation, limit drift between wallet and ledger, account wallet revocation not propagating to the virtual wallet. Output: PAY_AUTONOMOUS / ESCALATE / VERIFY_BOUND / ABORT verdict with evidence. Falsifier: free Cloudflare docs already describing the two-layer design, which this procedure extends with payment-specific thresholds.
