/// this blast radius be surfaced to the user. The Test Run panels in
/// <c>SharedScriptForm</c> and <c>TemplateEdit</c> carry a prominent
/// <c>Real I/O</c> badge and an <c>alert-warning</c> block stating the side
/// effects are real and permanent; <c>ApiMethodForm</c> (Inbound API kind) has
/// no real-I/O surface at all and correctly omits the badge. These tests pin
/// that warning so it cannot silently regress.
