Every diagnostic line in the audio path used `dart:developer`'s `log()`.
That function writes to the VM service, which a RELEASE build does not
have — so in the only build that ever runs in a car, all eleven of them
went nowhere. `debugPrint`/`print` do reach logcat in release; `log()`
does not.
That includes the two channels built specifically to end the guessing:
- `registrarErrorAudioService`, which subscribes to
`AudioService.asyncError` so the plugin's swallowed platform exceptions
stop vanishing (b0271fa). It moved them from a dropped PublishSubject
to a dropped log call.
- `_trazarEstadoPublicado`, the published-state trace added in 7054a4c to
settle why the car's play button never becomes pause.
So "no evidence" was never a quiet app. It was an app writing its
evidence somewhere release builds discard. Several rounds of hypotheses
were argued without data that the app was already producing.
All eleven now use `debugPrint` with a `[PluriWave][Tag]` prefix, so one
filter catches the audio path and the existing alarm lines together:
adb logcat | grep PluriWave
No behaviour changes. Tests: 1158, unchanged.
Adds "Reproducir carpeta" (sequential) and "Reproducir aleatorio"
(Fisher-Yates over the name-sorted order) as folder-scoped playable
actions, with auto-advance on track completion and skip next/prev.
Isolation from live radio is structural, not disciplinary: the
public playMediaItem always clears the local queue on any call, and
a new private _encolarCambioFuente is the only path that can advance
within it. _cambiarFuente, ControladorReconexion, and the reconnect
error path are untouched -- confirmed by a byte-for-byte empty diff
on all 4 pre-existing radio/reconnect regression suites, independently
re-run before and after (21/21 both times).
Handler wiring itself is static-review-only (PluriWaveAudioHandler
can't be unit-instantiated); the isolation/advance/race-guard
decision logic is extracted into cola_local.dart's pure functions,
which are fully unit-tested.
