# Verification Report: android-auto-eq-presets **Mode**: Strict TDD | **Verdict**: PASS ## Completeness All 21 tasks in `tasks.md` (Phases 1-5) are checked complete and match the live code. No task marked complete lacks a corresponding code/test change. ## Test Execution Evidence (independently re-run, not trusted from apply-progress) | Command | Result | |---|---| | `flutter test test/servicios/navegacion_auto_test.dart --concurrency=1 --timeout=60s` (compact reporter) | 46/46 passed | | Same file, `-r json`, counted `testDone` events | 46 (independently confirmed via JSON reporter, not just trusting the compact-reporter tally) | | `flutter test test/estado/estado_radio_test.dart --concurrency=1 --timeout=60s` (favorite-groups regression suite, shared `playFromMediaId`/dispatch surface) | 22/22 passed (JSON `testDone` count also 22) | Apply-progress's claimed 46/46 for `navegacion_auto_test.dart` is accurate. The extra regression pass on `estado_radio_test.dart` (not part of apply-progress's own claims) also passes clean - no regression on the favorite-groups feature that shares the touched dispatch surface. ## Load-Bearing Invariant: EQ selection never disturbs playback Traced `playFromMediaId` (`lib/servicios/servicio_audio.dart:781-820`) directly in the live file: - The `esPresetMediaId(mediaId)` branch is the first statement inside the (now single) outer `try`, before `_fuenteNavegacionGlobal` is even read. - It ends with an unconditional `return;` - genuinely cannot fall through to `reproducirPorMediaId`/`playMediaItem`. - No `mediaItem` mutation, no `play()`/`setUrl()`/reconnect call anywhere in that branch - only `ServicioEcualizador()` construction and `aplicarPresetPorMediaId(...)`. Traced `aplicarPresetPorMediaId`'s actual signature (`lib/servicios/navegacion_auto.dart:364-371`, read directly, not from docstring): ``` Future aplicarPresetPorMediaId( String id, { required List presets, required String? uuidActual, required Future> Function() clavesPorEmisora, required Future Function(PresetEcualizador) persistirPrincipal, required Future Function(PresetEcualizador) aplicar, }) ``` Confirmed: no `playMediaItem`, `mediaItem`, or `playbackState` parameter exists - structurally impossible to inject a playback seam. This matches the docstring claim and the dedicated structural test (`navegacion_auto_test.dart:755-784`). ## Root Folder Count - `ConstructorArbolAuto.raiz()` (`lib/servicios/navegacion_auto.dart:171-176`) returns 4 folders, `Ecualizador` last, `playable: false`. - `test/servicios/navegacion_auto_test.dart:226` - `expect(raiz, hasLength(4))` - confirmed updated (line number shifted from the apply-progress's original estimate of 225 to 226 due to file growth, as anticipated by the reviewer's warning; content matches). - Line 241-242 additionally assert `raiz.last.id == idEcualizador` and `raiz.last.playable == false` (ADR-2 last-position + non-playable, beyond the base spec's minimum). - Grepped the full `test/` tree for other `raiz()`/root-count assertions: only `navegacion_auto_test.dart` matches - confirms task 4.2's claim. ## Persistence Seam Grepped both call sites in the diff: - `servicio_audio.dart:800` - `persistirPrincipal: servicio.guardarPrincipal` -> `ServicioEcualizador.guardarPrincipal` (`servicio_ecualizador.dart:129-132`, writes SharedPreferences key `eq_preset_principal_v1`). - No call to `EstadoEcualizador.cambiarPresetPrincipal` anywhere in the diff or the new code paths (confirmed via grep across `navegacion_auto.dart`/`servicio_audio.dart`). - Matches ADR-4 exactly: handler + service seam, not the phone's `ChangeNotifier`. ## debeAplicarPrincipalAhora Gate Parity Read both gates directly: - `estado_ecualizador.dart:302-304`: `uuid == null || !_presetsEmisoraMap.containsKey(uuid)` - `navegacion_auto.dart:348-351`: `uuidActual == null || !clavesPorEmisora.contains(uuidActual)` Also traced that `clavesPorEmisora` is populated from `servicio.cargar().porEmisora.keys`, and `servicio_ecualizador.dart`'s `cargar()` reads `porEmisora` from the same persisted per-station map that populates `EstadoEcualizador._presetsEmisoraMap` (`estado_ecualizador.dart:161-163`, `..addAll(config.porEmisora)`). The two gates are genuinely operating over the same underlying data, not just superficially similar in shape. ## Unknown/Stale Preset ID `resolverPresetEq` returns `null` for unknown name / empty-after-prefix / non-`eq_preset:` id (`navegacion_auto.dart:332-340`). `aplicarPresetPorMediaId` returns immediately on `null` without invoking either seam. Test (`navegacion_auto_test.dart:731-753`) asserts `persistirLlamadas == 0` and `aplicarLlamadas == 0` for `'eq_preset:Inexistente'` - the assertion is on call counts, not just a test name; genuinely proves the no-op. ## Active Preset Indication (Optional requirement) Confirmed OUT OF SCOPE as designed (ADR-6). Grepped `navegacion_auto.dart` for marker/selection-related terms - no half-built UI, no dead marker code, no leftover scaffolding. `itemPresetEq` emits only the plain preset name as `title`. ## Deviations Self-Reported by apply-progress.md - Verified 1. servicio_ecualizador.dart import added to servicio_audio.dart, not listed in task 3.3's enumerated file list. Confirmed real: `git diff` shows `+import 'servicio_ecualizador.dart';` at the top of the file; task 3.3's text only mentions verifying the `preset_ecualizador.dart` import. This is a genuine (harmless) task-description gap, not a code defect. 2. playFromMediaId restructured to a single outer try/catch. Confirmed real via `git diff`: previously `final fuente = _fuenteNavegacionGlobal; if (fuente == null) return;` sat OUTSIDE the try block; now both lines are inside the try, after the new `eq_preset:` branch. Behaviorally inert for the pre-existing `emisora:`/`grupo:` path - the null-check itself cannot throw, so moving it inside `try` changes nothing observable. Verified via the full `estado_radio_test.dart` (22/22) and `navegacion_auto_test.dart` (46/46, includes `reproducirPorMediaId` tests) suites, both green. ## Diff Size Cross-Check `git diff --stat` on the three touched files: ``` lib/servicios/navegacion_auto.dart | 94 ++++++++++++- lib/servicios/servicio_audio.dart | 26 +++- test/servicios/navegacion_auto_test.dart | 226 ++++++++++++++++++++++++++++++- 3 files changed, 339 insertions(+), 7 deletions(-) ``` 339 + 7 = 346 changed lines - matches apply-progress's self-reported figure exactly. Within the 300-420 forecast, under the 400-line budget. ## Cleanliness Checks - No AI attribution strings found in the diff (`Co-Authored-By`, `Generated with`, `Claude`, `ChatGPT`, etc. - none matched). - No stray `print`/`debugPrint` calls introduced. - No `TODO`/`FIXME` markers introduced. - No dead code found in the reviewed hunks. - Working tree: `navegacion_auto.dart`, `servicio_audio.dart`, `test/servicios/navegacion_auto_test.dart` are modified-but-unstaged; `openspec/changes/android-auto-eq-presets/` is untracked. Nothing has been committed - confirmed via `git log` (HEAD is still `066fedb`, predating this change) and `git status`. ## Spec Compliance Matrix | Spec Requirement | Status | Evidence | |---|---|---| | Browsable Media Tree (4 folders, Ecualizador included) | PASS | raiz() + test at line 226 | | EQ Preset Browsable Folder (6 items, eq_preset:) | PASS | presetsEq/itemPresetEq + tests | | EQ Preset Selection Applies Without Disturbing Playback | PASS | Structural signature proof + first-branch/unconditional-return trace | | EQ Preset Persistence and Phone/Car Parity | PASS | guardarPrincipal call site confirmed, SP key shared with phone | | Active Preset Indication (Optional) | PASS (scoped out) | ADR-6, no half-built code | ## Design Coherence All 6 ADRs (ADR-1 through ADR-6) traced against live code - implementation matches design as documented. No undocumented deviation found beyond the two apply-progress already self-reported (both verified genuine and low-risk). ## Issues Found None CRITICAL. None WARNING. None SUGGESTION beyond a purely cosmetic note: apply-progress's line-number references (e.g. "225" vs actual "226") drift slightly as the file grows - informational only, does not affect correctness or task completeness. ## Final Verdict PASS - 0 CRITICAL, 0 WARNING, 0 SUGGESTION (one informational-only line-number drift note, not a defect).
