Archive Report: android-auto-favorite-groups

Date: 2026-07-19 Status: PASS WITH WARNINGS → ARCHIVED Artifact Store: hybrid (openspec + engram)

Change Summary

Change Name: android-auto-favorite-groups Proposal: Expose favorite groups (GrupoFavoritos) as browsable, non-playable sub-folders in the Android Auto browse tree under the existing Favoritos folder, leveraging the existing group data model without introducing new schema or phone-UI changes.

Verification Verdict: PASS WITH WARNINGS

  • CRITICAL Issues: 0
  • WARNING Issues: 1 (test-count report accuracy in apply-progress.md, corrected to 54/54 before archive)
  • SUGGESTION Issues: 2 (non-blocking, low-priority)

Implementation Status: Complete (git commit f368bcc on main, 291 changed lines across 5 files)

Spec Synchronization

Main Spec Updated

File: openspec/specs/android-auto-media/spec.md

Changes Applied:

  1. ADDED: "Favorite Group Sub-Folders" requirement (3 scenarios)

    • Car requests Favoritos folder and groups exist
    • Car requests a group folder's stations
    • Car requests an unknown or stale group id
  2. ADDED: "Empty Favorite Group Handling" requirement (2 scenarios)

    • Empty group folder is browsed (if shown)
    • No user-facing dead end
  3. MODIFIED: "Browsable Media Tree" requirement

    • Updated description to note Favoritos MAY contain favorite-group sub-folders
    • Changed precedent note from "Previously: no subtitle requirement..." to "Previously: Favoritos was a flat folder of playable station items only, with no sub-folder nesting."
    • Added new scenario: "Ungrouped station appears exactly as before (regression guard)"

Summary: 2 new requirements (7 scenarios total), 1 existing requirement enhanced with 1 new scenario, maintaining full backward-compatibility for ungrouped stations.

Implementation Verification

Verification Command:

flutter test test/servicios/navegacion_auto_test.dart test/estado/estado_radio_test.dart --concurrency=1 --timeout=60s

Result: PASS — 54/54 tests

  • navegacion_auto_test.dart: 33/33 passed
  • estado_radio_test.dart: 21/21 passed

Files Changed (5 total, 291 changed lines):

  1. lib/servicios/navegacion_auto.dart — Added grupos() source, snapshot field, esCarpetaGrupo, itemGrupo, carpetasFavoritos, hijosGrupo methods
  2. lib/servicios/servicio_audio.dart — Added two new branches in getChildren dispatch
  3. lib/estado/estado_radio.dart — Push gruposFavoritos into Auto snapshot
  4. test/servicios/navegacion_auto_test.dart — Added 8 new test groups covering pure builders
  5. test/estado/estado_radio_test.dart — Updated fake, added snapshot-push assertion

Regression Guard: Regression parity test confirms byte-identical output for Favoritos folder when no custom groups exist — the no-custom-groups case reuses the existing hijos() path, not a parallel reimplementation.

Issues Summary

WARNING (1)

  1. Test-count report accuracy (apply-progress.md)
    • apply-progress.md originally claimed 55/55 tests (34/34 + 21/21)
    • Actual: 54/54 tests (33/33 + 21/21)
    • Status: Corrected before archive
    • Impact: Cosmetic documentation defect only; no missing coverage

SUGGESTIONS (2)

  1. 50-group cap boundary test — uses bulk-of-60 style, not exact 50-vs-51 boundary; consistent with pre-existing precedent
  2. Mixed browsable+playable children car-UI rendering — flagged as open question, requires DHU/hardware testing; carry forward as known residual risk

Rollback Information

Rollback is straightforward:

  • Revert the grupos() method and snapshot field from FuenteEmisorasAuto
  • Revert the two new branches in servicio_audio.dart getChildren
  • Revert the _fuenteAuto?.actualizarSnapshot(grupos: ...) push in estado_radio.dart
  • All changes are additive; pre-existing 3-folder tree, group CRUD, phone UI, and SQLite schema remain untouched

Verification Compliance

Requirement Status Evidence
Favorite Group Sub-Folders spec compliance PASS carpetasFavoritos test cases (459-524), esCarpetaGrupo prefix checks
grupo: collision-free vs emisora: PASS resolver collision test (557-565) confirms no-op for grupo: prefix
Empty group handling PASS empty-group fixture test (484-505) confirms omission from tree
Regression guard (ungrouped stations) PASS byte-identical output via direct hijos() reuse (navegacion_auto.dart:234, test 429-457)
Design coherence PASS All 7 design decisions verified against implementation
Task completion PASS All 22 tasks marked complete, confirmed by code inspection
TDD cycle compliance PASS 54/54 tests passing, pure functions fully unit-tested

SDD Cycle Closure

This change completes the full SDD cycle for android-auto-favorite-groups:

  1. Exploration: Investigation 1 (Approach 1 — data-model reuse)
  2. Proposal: Defined scope, capabilities, risks, rollback
  3. Spec: Delta spec with 2 new + 1 modified requirements
  4. Design: 4 architecture decisions, pure-function seam strategy
  5. Tasks: 5 phases, 22 tasks (foundation → core → wiring → testing → cleanup)
  6. Apply: Strict TDD, single PR, 291 changed lines, 54/54 tests green
  7. Verify: Fresh adversarial pass, PASS WITH WARNINGS (1 cosmetic, 2 suggestions)
  8. Archive: Specs merged, change folder moved, audit trail created

Next Steps

  • No follow-up required — change is complete and ready for release
  • Known residual risk: Mixed browsable+playable children rendering on real car UI — schedule DHU/hardware verification before launch if not yet done
  • Optional enhancement: Consider boundary test for 50-vs-51 group cap as a future refinement (non-blocking)
