From 8f7ca8059be758de791f56f87cd3932aac7dfeda Mon Sep 17 00:00:00 2001 From: freetlab Date: Fri, 10 Jul 2026 23:54:01 +0200 Subject: [PATCH] fix(eq): resolve base-speaker preset live instead of pinning a stale copy _onDispositivoCambiado() bootstrapped a device-level preset entry for every never-seen device id, including the built-in speaker. That persistent level-3 entry masked later global-preset edits (level 3 beats level 4 on every resolution), so disconnecting a BT device or cold-starting without one could leave the EQ stuck on an outdated copy instead of the current global preset. The base speaker is now excluded from the first-seen bootstrap: disconnect and cold start always resolve through the live hierarchy. BT/wired/USB devices keep their bootstrap behavior unchanged. --- lib/estado/estado_ecualizador.dart | 9 +- .../archive-report.md | 193 ++++++++++++++++ .../design.md | 76 +++++++ .../proposal.md | 62 +++++ .../specs/multi-device-eq/spec.md | 136 +++++++++++ .../state.yaml | 17 ++ .../tasks.md | 54 +++++ .../verify-report.md | 131 +++++++++++ openspec/specs/multi-device-eq/spec.md | 136 +++++++++++ test/estado/estado_ecualizador_test.dart | 214 ++++++++++++++++++ 10 files changed, 1026 insertions(+), 2 deletions(-) create mode 100644 openspec/changes/archive/2026-07-10-eq-device-disconnect-revert/archive-report.md create mode 100644 openspec/changes/archive/2026-07-10-eq-device-disconnect-revert/design.md create mode 100644 openspec/changes/archive/2026-07-10-eq-device-disconnect-revert/proposal.md create mode 100644 openspec/changes/archive/2026-07-10-eq-device-disconnect-revert/specs/multi-device-eq/spec.md create mode 100644 openspec/changes/archive/2026-07-10-eq-device-disconnect-revert/state.yaml create mode 100644 openspec/changes/archive/2026-07-10-eq-device-disconnect-revert/tasks.md create mode 100644 openspec/changes/archive/2026-07-10-eq-device-disconnect-revert/verify-report.md create mode 100644 openspec/specs/multi-device-eq/spec.md diff --git a/lib/estado/estado_ecualizador.dart b/lib/estado/estado_ecualizador.dart index 3f4c245..6d54dd4 100644 --- a/lib/estado/estado_ecualizador.dart +++ b/lib/estado/estado_ecualizador.dart @@ -212,8 +212,13 @@ class EstadoEcualizador extends ChangeNotifier { _dispositivoActualId = dispositivo.id;

No tautologies, ghost loops, assertion-free tests, or CSS/implementation-detail-only checks found across D.1-D.5. Every test drives real production code (_onDispositivoCambiado, _resolverPresetActivo, cargarPersistido) and asserts on production-derived values (presetActual, presetsDispositivo, FakeServicioAudio.presetsAplicados), consistent with the spec instruction to assert presetsAplicados (proves push, not state-only mutation) rather than state alone. + +Manually traced D.2 pre-fix versus post-fix behavior against the actual presetEfectivo hierarchy to independently confirm it is a genuine, non-tautological regression test (would have resolved presetActual == rock, stale, pre-fix versus pop, fresh, post-fix on the second builtin_speaker emit). This matches the claim already documented in apply-progress that D.2 is the only test among D.1-D.5 that targets the actual bootstrap-collision bug. + +**Assertion quality**: All assertions verify real behavior. + +--- + +### Quality Metrics +**Linter/Analyzer**: No errors. flutter analyze reported zero issues (ran this session, full project, 63.6s) +**Type Checker**: N/A separate tool; covered by flutter analyze (Dart static analysis) + +### Issues Found + +**CRITICAL**: None + +**WARNING**: +1. Spec scenario text versus implementation divergence, Requirement 2 "First-Seen Bootstrap Must Not Hijack Base-Device Resolution". The spec scenario literally states that the presetsDispositivo entry for builtin_speaker is bootstrapped to rock (global fallback), implying the key gets created with the correct value. The actual implementation, matching Design Decision 2 and its explicit reasoning ("Rejected: keep and tolerate, leaves persisted mask bug"), NEVER creates that entry at all. The esBase guard unconditionally skips the whole bootstrap block, so the presetsDispositivo containsKey check for builtin_speaker stays false forever, proven by test D.2. This is objectively safer than the literal scenario (D.2 proves it prevents the L3-masks-L4 bug that a bootstrap-with-correct-value approach would not prevent) and is fully justified by the design document rationale; it is not a functional defect. But it means a reader following the spec literally would expect that containsKey check to be true, which is false: a real drift between spec-as-written and spec-as-implemented. Recommendation: before archive, update the spec scenario THEN clause to state that the entry is never bootstrapped and always resolves live through the hierarchy, so the spec matches the safer, already-implemented, already-tested behavior. + +**SUGGESTION**: +1. Reconcile spec text per WARNING-1 recommendation before archive (listed there to avoid double-counting). +2. The apply-progress TDD Cycle Evidence table uses a 3-column format (RED/GREEN/REFACTOR plus prose) instead of the full 5-column strict-TDD template (RED/GREEN/TRIANGULATE/SAFETY NET/REFACTOR). Substance is all present and was cross-verified independently in this session, but a future sdd-apply run should use the standard table shape for easier automated auditing. +3. The apply-progress "Issues Found" section already flags, correctly, as out-of-scope for this change, that cambiarPresetPrincipal immediate re-apply bypasses _resolverPresetActivo and applies the raw global value directly rather than through the hierarchy. Carrying this forward as a tracked tech-debt item; no action needed in this change, but worth a follow-up ticket since it could theoretically let a station/matrix override be transiently bypassed for one apply call when the global preset changes. + +### Verdict +**PASS WITH WARNINGS** + +0 CRITICAL, 1 WARNING (spec-text/implementation wording drift on Requirement 2, functionally sound and safer than written; recommend a spec-text correction before archive), 3 SUGGESTION. All 43 tests in the target file pass (including all 5 new Phase-D tests and every named consistency lock: 5.5b, 5.7a, 5.8b, 2.2), flutter analyze is clean, the code change matches the design Bootstrap Guard block exactly (verified via git diff and direct source read), and 15/16 tasks are complete with task 5.1 intentionally left as the non-blocking manual on-device gate. diff --git a/openspec/specs/multi-device-eq/spec.md b/openspec/specs/multi-device-eq/spec.md new file mode 100644 index 0000000..91dafac --- /dev/null +++ b/openspec/specs/multi-device-eq/spec.md @@ -0,0 +1,136 @@ +# Delta for multi-device-eq + +No prior `openspec/specs/multi-device-eq/spec.md` exists.
