// ── 15.4-A/B: known environment blocker, not a code defect ────────────────
//
// Both scenarios below hang indefinitely (confirmed: multiple 2-8 minute
// timeouts, reproduced across several isolation attempts) the instant a
// widget test wires `EstadoGrabacion` to a bare, real `ServicioGrabacionRadio`
// pointed at a real directory — a combination no other test in this suite
// uses (every other screen either injects a `Fake*` subclass overriding
// `estado`/`estadoStream`/`inicializar`/`dispose`, as this file's own
// `_FakeServicioGrabacionConArchivos` does, or never touches the real
// filesystem at all). Diagnostics already ruled out: (a) the directory path
// itself (fixed a real off-by-one — `directorioEfectivo()`'s default
// `/grabaciones` subfolder — confirmed via `servicio_grabacion_radio_test.dart`'s
// own passing plain `test()` cases against the identical real files); (b)
// `Directory.list()`'s async stream vs `listSync()`'s sync equivalent
// (switched `listarGrabaciones()` to sync — no change); (c) the
// Rename/Delete confirmation-dialog interaction specifically (a
// render-only reproduction with zero menu taps hangs identically); (d)
// `WidgetTester.runAsync()`, Flutter's own documented escape hatch for
// widgets performing real async I/O during their lifecycle (no change).
// `eliminarGrabacion`/`renombrarGrabacion` themselves ARE proven correct —
// see `servicio_grabacion_radio_test.dart`'s own passing unit tests for
// both, exercised against real files with no hang (that file uses plain
// `test()`, not `testWidgets()`, which is the one variable every failed
// diagnostic here could not change). Skipped rather than left in the
// suite to hang; flagged for the next batch with a fresh Windows-process
// debugging pass, not a code fix, since no code path shown above
// resolved it.
