POST /pkg/preflight/batch

method-gated

Batch install-safety preflight for a whole dependency list or parsed manifest (up to 100 packages). Returns a verdict per package plus a blocked / caution / safe summary. Supply-chain indicators, not a guarantee.

Verdict: not verified by an unpaid GET. 405/400: the 402 sits behind the declared method. This says nothing about whether the route works when called as declared.

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
