end;

Default selects asynchronous signing, HTTPS-only endpoints, automatic SAD authorization, two transient retries, a 64-signature local batch ceiling, finite poll and payload budgets, stable idempotency keys, and a 128-operation cache

AllowInsecureHTTP exists only for controlled development endpoints and still rejects non-HTTP schemes
