// TestNoFloatingPromisesChecksIIFEByDefault locks the default half of the
// ignoreIIFE option while TestNoFloatingPromisesOptions covers the opt-out.
//
//  1. Discard an async IIFE under scalar defaults.
//  2. Run the real checker-backed rule command.
//  3. Assert the IIFE is the single reported Promise.
//
// @evidence contracts/testing.md#behavioral-verification Async IIFEs must report by default.
// @evidence contracts/testing.md#independent-expectations Independently authored source and original assertions require exact error lines 1, code 2 and empty stdout for reporting command runs; all original inputs/options and clean arms are retained.
// @evidence contracts/testing.md#distinguishing-cases Options exercises ignoreIIFE=true on the same async-IIFE shape while retaining other active checks.
// @evidence contracts/testing.md#execution-ownership TestNoFloatingPromisesChecksIIFEByDefault invokes the in-process check command over a real Program/Checker through the owning floating-promise fixture helpers in one Go unit process, without a native build, installed consumer or compiler child.
