+# Archive Report: EQ Device Auto-Switch UX
+
+**Change Name**: `eq-device-autoswitch-ux`  
+**Archive Date**: 2026-06-28  
+**Status**: COMPLETE — All requirements met, all tests passing, ready for closure.
+
+---
+
+## Executive Summary
+
+The **eq-device-autoswitch-ux** change is COMPLETE and ARCHIVED. All 18 spec scenarios pass. Device startup seeding bug fixed. Device rename persistence, connection indicators, and edit modal fully implemented. 231 tests green, analyzer clean. 2 CRITICAL and 3 WARNING issues identified in initial verification were all resolved in the fix round. Delivered via 3 chained PRs.
+
+---
+
+## Change Intent
+
+Enable multi-device EQ management with:
+- **Startup device seeding**: Call `obtenerDispositivoActual()` in `cargarPersistido()` to seed device at app launch
+- **Device rename persistence**: `eq_nombres_dispositivos_v1` SharedPreferences key for custom device names
+- **Display name fallback**: customName → platformName → deviceId
+- **Connection indicator**: Green dot on active device in Settings
+- **Edit modal**: Tap device to open bottom sheet with rename TextField + embedded EcualizadorWidget

+
+## Verification Results
+
+### Initial Verdict (First Verify Run)
+**PASS WITH WARNINGS** — 2 CRITICAL, 3 WARNING, 2 SUGGESTION issues found.
+
+#### CRITICALs (both fixed)
+
+**CRITICAL-1**: Toggle-off no-op for rename not implemented
+- **Issue**: No guard on `_eqMultiDeviceEnabled` in `renombrarDispositivo()`
+- **Fix**: Added `if (!_eqMultiDeviceEnabled) return;` at method entry + 2 new tests
+- **File**: `lib/estado/estado_ecualizador.dart`
+- **Tests**: `test_renombrarDispositivo_cuando_multiDispositivoDeshabilitado_esNoOp` (2 variants)
+
+**CRITICAL-2**: EQ changes in modal discarded on save
+- **Issue**: No public method to save preset to `presetsDispositivo[deviceId]`; modal only called `renombrarDispositivo()`
+- **Fix**: Added `guardarPresetDispositivo(String deviceId, PresetEcualizador preset)` method; modal now calls it
+- **Files**: `lib/estado/estado_ecualizador.dart`, `lib/pantallas/pantalla_ajustes.dart`
+- **Tests**: 4 new tests covering device-level preset save, with/without active device
+
+#### WARNINGs (all fixed)
+
+**WARNING-1**: Platform name fallback unreachable from UI
+- **Status**: FIXED in implementation — `_FilaDispositivo` now receives and passes `DispositivoAudio.nombre` to fallback chain
+- **No regression risk**: Fallback chain already handles null/empty gracefully
+
+**WARNING-2**: 7 locales missing translations (pt, it, ja, zh, ru, bn, id)
+- **Fix**: Added all 5 `eqDevice*` keys to all 7 locale files + ran `flutter gen-l10n`
+- **Files**: `lib/l10n/app_pt.arb`, `app_it.arb`, `app_ja.arb`, `app_zh.arb`, `app_ru.arb`, `app_bn.arb`, `app_id.arb`
+
+**WARNING-3**: FakeServicioEcualizador drops `nombresDispositivos` on save
+- **Fix**: Updated `guardarPrincipal()` and `guardarActivo()` to preserve `nombresDispositivos` in reconstructed config
+- **File**: `test/helpers/fakes.dart`
+- **Tests**: 2 new tests verify preservation
+
+### Final Verdict (After Fix Round)
+**ALL PASS** — 231/231 tests green, `flutter analyze` clean, no issues remaining.

+## Chained PRs Delivered
+
+| PR | Title | Base | Files | Lines | Tests | Status |
+|----|----|------|-------|-------|-------|--------|
+| #1 | feat(eq): per-device EQ rename + persistence | main | 3 | ~150 | 6 | MERGED |
+| #2 | feat(eq): device modal + indicators | PR #1 | 4 | ~220 | 4 | MERGED |
+| #3 | test(eq): complete modal + device tests | PR #2 | 2 | ~45 | 4 | MERGED |
+
+---
+
+## Known Deferred / Out of Scope
+
+1. **Task 3.3**: Modal scrollability widget test (viewport test — LOW PRIORITY, not blocking)
+2. **Task 3.9**: Extract `_DialogoEdicionDispositivo` to separate file (pantalla_ajustes.dart at 1450 lines is acceptable; extraction can be future refactor)
+3. **Proposal Risk**: `nombresDispositivos` not in export schema v4 (acknowledged, deferred per proposal)
+
+---
+
+## Rollback Plan
+
+All changes are **additive**:
+- Remove commit(s) → reverts all code and new SP key (`eq_nombres_dispositivos_v1`) is ignored
+- No data loss; backwards-compatible with prior state
+- Startup seeding is a single method call — removing it restores prior (broken) behavior
+
+---
+
+## Testing Evidence
+
+**Build & Test Command**:
+```
+flutter test
+flutter analyze
+```
+
+**Results**:
+- `flutter test`: 231 tests ALL PASS ✓
+- `flutter analyze`: No issues found ✓
+
+**Coverage**:

+- CRITICAL-2 guardarPresetDispositivo tested (4 tests, device active & inactive) ✓
+- WARNING-2 locales (7 files, all keys present) ✓
+- WARNING-3 FakeServicio preservation (2 tests) ✓
+
+---
+
+## Next Steps
+
+**None**. The change is COMPLETE and CLOSED.
+
+- Implementation ready for production
+- All tests passing
+- Spec fully satisfied
+- No open CRITICALs or WARNINGs
+- 3 chained PRs merged to main
