Javier Bautista Fernández d579a0e107 feat: Implement startup retry mechanism for custom stations and equalizer persistence 
- Added state management for startup retry and custom station handling in `EstadoRadio`.
- Created tasks for implementing strict TDD with RED tests for HTTP failure retries and EQ persistence.
- Developed verification report to ensure compliance with TDD practices.
- Introduced fake services for testing, including `FakeServicioAudio`, `FakeServicioFavoritos`, and `FakeServicioRadio`.
- Implemented widget tests for `PantallaInicio` and `PantallaFavoritos` to validate UI behavior with custom stations.
- Enhanced `ServicioRadio` to support host rotation and retry logic for API calls.
- Established a new configuration file to enforce project constraints and testing rules.

Raw Blame History

Verification Report: startup-retry-custom-stations-eq-persistence

Status: blocked
Mode: Strict TDD
Date: 2026-04-27
Verifier: sdd-verify worker 2
Round: re-verify after targeted apply-fix

Runtime verification remains blocked because flutter is not available in PATH in this shell. Static review confirms the targeted fixes from the prior verification round are present. This change is still not archiveable because Strict TDD requires passing flutter test evidence before scenarios can be marked compliant and before tasks 5.3/5.4 can be completed.

Completeness

Metric Value
Tasks total 23
Tasks complete 21
Tasks incomplete 2

Incomplete by design until runtime evidence exists:

  • [ ] 5.3 VERIFY: Run flutter test only; never run flutter build.
  • [ ] 5.4 VERIFY: Compare passing tests against every Given/When/Then scenario in spec.md.

Tasks 5.3 and 5.4 must remain incomplete. flutter test was attempted and could not run because Flutter is missing from PATH.

Validation Commands Attempted

Command Exit Result
git status --short 0 Confirmed active uncommitted work exists; verification did not revert or edit production code.
Get-Command flutter -ErrorAction SilentlyContinue 127 FLUTTER_NOT_FOUND: Get-Command flutter returned no executable on PATH.
flutter test 1 CommandNotFoundException: flutter is not recognized as a cmdlet/program in this PowerShell session.
flutter build N/A Not run; prohibited by project and mission constraints.

Coverage, linter, and type-check commands were not run because the configured tools are Flutter-backed (flutter test --coverage, flutter analyze) and Flutter is unavailable.

TDD Compliance

Check Result Details
TDD Evidence reported PASSED STATIC apply-progress.md now contains ## TDD Cycle Evidence.
Test files exist PASSED STATIC Verified test/servicios/servicio_radio_test.dart, test/estado/estado_radio_test.dart, and test/pantallas/pantalla_inicio_test.dart.
RED confirmed PARTIAL / BLOCKED Test intent is documented and test files exist, but RED-first ordering cannot be independently proven without historical run output.
GREEN confirmed BLOCKED flutter test cannot execute in this environment.
Triangulation adequate PARTIAL / BLOCKED Targeted missing scenarios now have tests; runtime proof is blocked.
Safety net for modified files BLOCKED Apply-progress records the same Flutter availability blocker.

TDD compliance verdict: blocked. The prior missing-evidence-table finding is fixed, but Strict TDD cannot pass until flutter test runs successfully.

Scenario Coverage Matrix

Runtime result is BLOCKED for every scenario because no test execution was possible. Under Strict TDD, no scenario can be marked compliant until a covering test has passed.

Requirement Scenario Static implementation evidence Test evidence found Result
Startup radio loading resilience transient startup failure recovers ServicioRadio._get() retries with host rotation; EstadoRadio._init() calls station loading after EQ load. test/servicios/servicio_radio_test.dart covers retry/host rotation success. No direct EstadoRadio startup integration test for final visible error clearing, but design assigns retry ownership to ServicioRadio. PARTIAL STATIC / BLOCKED
Startup radio loading resilience startup failures are exhausted ServicioRadio._get() caps attempts; EstadoRadio.cargarPopulares() exposes Sin conexión a la API de radio; PantallaInicio has Reintentar. Service cap/error test exists. State and widget tests now cover startup failure plus manual retry recovery. COVERED STATICALLY / BLOCKED
Custom stations in main listing added custom station appears on home EstadoRadio.emisorasInicio combines custom + popular; PantallaInicio uses it without genre filter; tap calls EstadoRadio.reproducir. State getter test exists. Widget test now renders Custom Uno and taps it, asserting fake audio playback and click registration. COVERED STATICALLY / BLOCKED
Custom stations in main listing custom station can be favorited TarjetaEmisora uses the same EstadoRadio.toggleFavorito flow for all station cards; toggleFavorito reloads favorites. Widget test taps favorite on the custom station. Widget test now opens PantallaFavoritos and verifies the custom station appears after reload. COVERED STATICALLY / BLOCKED
Main equalizer persistence main EQ restores after restart ServicioEcualizador.cargar() loads persisted main EQ; EstadoRadio._cargarEcualizadorPersistido() sets provider state before station loading; playback applies selected EQ. State test covers persisted main EQ before playback EQ selection. COVERED STATICALLY / BLOCKED
Main equalizer persistence EQ state persists even when native EQ is unavailable EstadoRadio loads persisted EQ independent of audio.ecualizadorDisponible; production ServicioAudio.aplicarPreset() stores _presetActual before returning when native EQ is unavailable. State test now uses FakeServicioAudio(ecualizadorActivo: false) and verifies main + per-station persisted EQ remain exposed. COVERED STATICALLY / BLOCKED
Favorite station equalizer mode favorite station own EQ is applied _presetParaEmisora() prefers _presetsEmisoraMap[uuid]; reproducir() applies selected preset and updates state. State test covers own EQ overriding main. COVERED STATICALLY / BLOCKED
Favorite station equalizer mode favorite station falls back to main EQ Map absence falls back to _presetPrincipal. State test now covers a favorite without own EQ using main EQ from first play. COVERED STATICALLY / BLOCKED
Favorite station equalizer mode disabling own EQ restores main behavior deshabilitarPresetEcualizadorPorEmisora() removes persisted entry and applies main when current station matches. State test covers disabling own EQ and replaying with main fallback. COVERED STATICALLY / BLOCKED
Test-first implementation strict TDD guardrail openspec/config.yaml and state.yaml have Strict TDD active; apply-progress.md now records TDD cycle evidence and blocked Flutter commands. TDD table exists, but flutter test cannot run, so GREEN evidence is unavailable. PARTIAL STATIC / BLOCKED

Runtime compliance summary: 0/10 scenarios compliant because no covering test has passed in this environment.
Static coverage summary: 8/10 scenarios covered statically, 2/10 partial statically.

Correctness: Static Structural Evidence

Requirement Status Notes
Startup radio loading resilience PARTIAL STATIC Retry/host rotation and exhausted retry behavior exist. Manual retry coverage was added. Automatic transient startup recovery is proven primarily at the service layer, not with a direct EstadoRadio startup integration test.
Custom stations in the main listing IMPLEMENTED STATICALLY Combined listing, normal playback path, same favorite flow, and favorites screen reload are represented in code/tests.
Main equalizer persistence IMPLEMENTED STATICALLY EQ persistence service, provider load, native-unavailable state retention, and playback application are represented in code/tests.
Favorite station equalizer mode IMPLEMENTED STATICALLY Own EQ, main fallback, and disabling own EQ are represented in state code/tests.
Test-first implementation BLOCKED Strict TDD metadata and TDD evidence table exist; runtime GREEN evidence is blocked by missing Flutter.

Coherence: Design Decisions

Decision Followed? Notes
API retry owner in ServicioRadio._get() Yes Bounded retry/host rotation remains centralized in ServicioRadio._get().
Custom stations home UX via combined listing Yes EstadoRadio.emisorasInicio combines custom + popular; PantallaInicio uses it when no genre filter is selected.
EQ storage in ServicioEcualizador with SharedPreferences JSON Yes ServicioEcualizador stores main and per-station EQ JSON.
Station EQ fallback by Map<uuid, PresetEcualizador> absence Yes _presetParaEmisora() returns station preset or main preset.
Current station source in ServicioAudio/handler Yes static ServicioAudio sets/clears emisoraActual; the previously shadowed playMediaItem exception path now uses this.mediaItem.add(null).

Assertion Quality Audit

Reviewed related tests:

  • test/servicios/servicio_radio_test.dart
  • test/estado/estado_radio_test.dart
  • test/pantallas/pantalla_inicio_test.dart

Assertion quality: PASSED STATIC REVIEW. No tautological assertions, ghost loops, or smoke-only widget tests were found in the reviewed change tests. Assertions check concrete behavior: host sequence, call counts, visible text, persisted favorite state, selected EQ preset, and playback calls.

Issues Found

CRITICAL

None found in static re-review after the targeted fixes.

WARNING

  1. Runtime verification is blocked because Flutter is unavailable. This is not a production-code defect, but it blocks Strict TDD completion and archive.
  2. The transient startup recovery scenario is still proven most directly at ServicioRadio level rather than by a direct EstadoRadio.inicializar() integration test that starts with a transient service failure and ends with no visible startup error. Given the design decision that retry ownership lives in ServicioRadio, this is a coverage nuance, not a new blocker beyond runtime execution.

SUGGESTION

  1. When Flutter is available, run flutter test first; only after it passes should tasks 5.3/5.4 be marked complete.
  2. Consider adding one direct EstadoRadio.inicializar() transient-recovery test later if the team wants tighter end-to-end coverage for the first startup scenario.

Changed File Coverage

Coverage analysis skipped: Flutter is unavailable, so flutter test --coverage cannot run.

Quality Metrics

Linter: Not run (flutter analyze requires Flutter in PATH).
Type checker: Not run (flutter analyze requires Flutter in PATH).
Build: Not run; build commands are prohibited by project and mission constraints.

Tasks 5.3 / 5.4 Status

Task Status Reason
5.3 VERIFY: Run flutter test only; never run flutter build. INCOMPLETE flutter test was attempted but failed before execution because the flutter command is unavailable.
5.4 VERIFY: Compare passing tests against every Given/When/Then scenario. INCOMPLETE No test passed at runtime in this environment, so scenario compliance cannot be accepted under Strict TDD.

Do not mark either task complete until flutter test actually passes.

Verdict

BLOCKED, not archiveable.

Static targeted fixes are present and no new static blockers were found, but Strict TDD runtime verification cannot pass without a successful flutter test run.

Next Recommended

  1. Install/expose Flutter on PATH for the verification environment.
  2. Run flutter test only; do not run flutter build.
  3. If tests pass, update tasks 5.3/5.4 and rerun verify to produce a passing scenario compliance matrix.

Risks

  • Until flutter test runs, compile errors or failing tests may still exist undetected.
  • Archive would be premature because Strict TDD requires passing behavioral evidence, not just static review.
