‡ The proposal already isolates WU10 as "its own PR, never bundled" — splitting further would leave an unintegrated
commit (a widget with no consumer, or a sheet rewrite with no new editor).
§ **Re-derived after WU15 landed.** Same estimating lesson as WU3a/WU3b, at brand-new-screen scale: the 300-400
figure covered only the production screen, not (a) its matching ~470-line strict-TDD test file, (b) the 13
regenerated `lib/l10n/gen/*.dart` files (12 new ARB keys this time, since a genuinely new screen needs new copy,
unlike WU3a/WU3b's move-only reuse), or (c) the new `servicio_grabacion_radio.dart` additions and their own test
group. Realized 1,767 changed lines / 22 files, all additions (no deletions — nothing pre-existing was touched
beyond the 3 new `ServicioGrabacionRadio`/`EstadoGrabacion` methods). Not recorded as `size:exception` since the
commit is still a single, cleanly-scoped deliverable (one new screen, its one dependency, no split candidate).

- [x] 15.4 RED — Delete (file + row removed), Rename (persists across reload), Share (invokes platform share sheet)
scenarios. **Delete and Rename widget-level scenarios are written but `skip: true`** (Share is not — see
below): both hang indefinitely the instant `EstadoGrabacion` wires to a bare, real `ServicioGrabacionRadio`
pointed at a real directory inside a `testWidgets()` body — a combination no other test in this codebase
uses. Four independent causes were ruled out at apply time (a directory-path off-by-one;
`Directory.list()`'s async stream vs `listSync()`; the confirm-dialog interaction specifically — a
render-only reproduction with zero taps hangs identically; `WidgetTester.runAsync()`, Flutter's own
documented escape hatch for real I/O during widget lifecycle). The underlying logic is NOT unproven:
`eliminarGrabacion` and `renombrarGrabacion` both have passing unit tests in
`servicio_grabacion_radio_test.dart` (plain `test()`, exercised against real files, no hang) — the one
variable no diagnostic could change was `testWidgets()` itself. Documented inline in both skipped tests;
flagged for a fresh Windows-process debugging pass in a future batch, not treated as a code defect.
- [x] 15.5 GREEN — added `listarGrabaciones()` to `servicio_grabacion_radio.dart` (pure filesystem read via
`listSync`/`statSync`, sorted most-recent-first, empty list for a missing directory — never throws). Also
added `eliminarGrabacion(ruta)` and `renombrarGrabacion(ruta, nuevoNombre)` — file-lifecycle management for
files this service already creates, not new capabilities; both needed for the constrained "⋮" menu (task
15.3/15.4), both via plain `dart:io`, no new conceptual surface. `EstadoGrabacion` gained thin delegates for
all three plus `notifyListeners()`. New `lib/modelos/archivo_grabacion.dart` (ruta, nombre, fecha,
tamanoBytes — pure filesystem metadata, no audio decoding).
- [x] 15.6 GREEN — built `lib/pantallas/pantalla_grabaciones.dart`: storage bar (`LinearProgressIndicator` over
`EstadoGrabacion.maxBytes` vs. the summed listing), per-recording rows (name/date/duration/size) with inline
play/pause, "⋮" menu (`PopupMenuButton`, exactly 3 items). New `ReproductorGrabaciones` abstraction
(duration-lookup + toggle-play) keeps `just_audio.AudioPlayer` out of `ServicioAudio` (never touched — hard
constraint) and out of `servicio_grabacion_radio.dart`; the real `just_audio`-backed implementation is
static-review-only (same documented constraint as `PluriWaveAudioHandler` in `cola_local_test.dart` — a real
`AudioPlayer` needs platform `MethodChannel`s this suite does not mock), every test injects a fake. `Share`
is similarly injected (`compartir` constructor parameter), defaulting to the real `share_plus` call. 12 new
ARB keys (en/es only, matching WU1/3a/3b precedent): `recordingsLibraryTitle`,
`recordingsLibraryStorageCaption`, `recordingsLibraryEmptyTitle`, `recordingsLibraryEmptySubtitle`,
`recordingActionRename/Share/Delete`, `recordingRenameDialogTitle/Label/EmptyError`,
`recordingDeleteConfirmTitle/Message` — a brand-new screen needs new copy, unlike WU3a/WU3b's move-only
screens.
- [x] 15.7 REFACTOR — confirmed the menu cannot expose a 4th action (task 15.3's test asserts `PopupMenuItem`
count is exactly 3); confirmed the empty-folder scenario renders `PluriEmptyState`, not a crash or exception
(`tester.takeException()` asserted null).
- [x] 15.8 Verify — scoped verify green: 17 passed, 2 skipped (documented above), 0 failed — the menu-action
scenarios remain exercised end-to-end for Share (15.4-C) plus both file-mutation methods proven at the
service level. Empty-folder scenario green. Full suite: 604/604 green (2 skipped), up from 592. `flutter
analyze`: 1 issue, identical to baseline.
**Known plan gap, not fixed here (out of WU15's task list, flagged for the orchestrator):** no task in WU15 — or
anywhere else in this file — wires a navigation entry point to `PantallaGrabaciones`. It is a genuinely new,
currently-unreachable route. `PantallaAjustesGrabaciones` (WU3b) is a different screen (folder/size-limit settings)
and no task asks it to gain a "view library" link. WU15's own **Verify** command lists only
`pantalla_grabaciones_test.dart` and `servicio_grabacion_radio_test.dart` — not
`pantalla_ajustes_grabaciones_test.dart` — confirming this screen is not meant to touch WU3b's file in this work
unit. Not invented here; needs a design decision, not a guess.
