phase_status:
  Phase 1 (FGS Manifest + Runtime Type Fix): CANCELLED - 0/7 tasks, by design (target SDK constants confirmed fictional via javap -constants against android-34/35/36 platform jars + api-versions.xml sweep; existing mediaPlayback|systemExempted confirmed correct; Root Cause B withdrawn)
  Phase 2 (Kotlin Volume Override Channel Methods): COMPLETE - 9/9 tasks [x]
  Phase 3 (Dart Volume Override Port + Wiring): COMPLETE - 12/12 tasks [x]
  Phase 4 (Fade-In Dedup at Handoff): COMPLETE - 5/5 tasks [x]
  Phase 5 (Manual/On-Device QA): PENDING - 8 tasks [ ] (human gate, not executable by any agent)
  Phase 6 (Final Static Sweep): COMPLETE - 3/3 tasks [x]

test_results:
  total_changed_lines: "~260-360 estimated (Kotlin 2 files, Dart 3 prod files, 3 Dart test files); Slice 1 shipped 0 lines (cancelled by design)"

  post_verify_fix:
    commit: 79f6f8e
    what: "WARNING-1 closed: EstadoAlarmas captured in initState() instead of a fresh context.read() inside dispose(), which was throwing (caught, silently logged) on a defunct-widget-context ancestor lookup for any teardown that bypasses _detener()/_posponer(); plus a new dispose-as-sole-caller regression test"
    evidence: "35/35 alarm suites green, flutter analyze 0 issues"
    reflected_in_tasks_md: false

notes: |
  Phase 5 (manual/on-device QA) is a mandatory human gate before shipping, 8 tasks (5.1-5.8),
  requires real or emulated Android 14+ device access. Cannot be completed by any agent.

  Phase 1 (FGS manifest/runtime type fix) is CANCELLED by design, not a defect: sdd-apply
  independently verified via `javap -constants` against local android-34/35/36 platform jars
  plus a full FOREGROUND_SERVICE_TYPE_* sweep of api-versions.xml that FOREGROUND_SERVICE_TYPE_ALARM
  and android.permission.FOREGROUND_SERVICE_ALARM do not exist anywhere in the Android SDK. The
  existing mediaPlayback|systemExempted declaration is confirmed the correct, intentional pattern
  (matches the prior app-quality-and-native-alarms T-S1-03/04 deviation). Root Cause B from
  exploration is withdrawn; design.md and specs/native-alarms/spec.md both carry correction
  banners documenting this. Slices 2 and 3 are unaffected and both code-complete.

  WARNING-1 (dispose()'s restore call site non-functional as a standalone safety net, due to a
  defunct-widget-context ancestor lookup thrown — and silently caught — whenever dispose() is the
  first/only caller) was found during sdd-verify and CLOSED post-verify by the orchestrator via
  commit 79f6f8e: EstadoAlarmas is now captured in initState() rather than re-read via
  context.read() inside dispose(), plus a new dispose-as-sole-caller regression test. 35/35 alarm
  suites green, flutter analyze 0 issues. This fix is NOT reflected as a new checkbox in tasks.md
  (it is an orchestrator-level post-verify fix, not a numbered task) — documented here and in
  archive-report.md instead.

  WARNING-2 (task 3.9 has no automated RED/GREEN pair; app.dart's PluriWaveApp entry point
  hardcodes non-injectable EstadoRadio/EstadoAlarmas instances, so _prearrancarAudioAlarma cannot
  be exercised via flutter test in isolation) is accepted-documented, not fixed. Verified via
  source inspection instead (forzarVolumenMediaParaAlarma(1.0) confirmed the first statement in
  _prearrancarAudioAlarma). Recommended follow-up: add a testable DI seam to PluriWaveApp if
  genuine automated coverage of this seam is required later.

  Kotlin work (Phase 2 channel methods, Phase 2b flutterOwnsRing handoff-aware backstop) is
  code-inspection-verified only (no Android test harness in this repo, flutter build/gradle
  forbidden throughout). Native handoff-timing behavior will be validated during Phase 5 manual
  QA, specifically tasks 5.1 and 5.5.

  ARCHIVE TOOLING CAVEAT: the sdd-archive executor for this change had no Bash/shell tool
  available (Read/Edit/Write/Glob/mem_* only) and could not run `cp` or delete the source folder.
  All six on-disk artifacts (explore.md, proposal.md, design.md, tasks.md, verify-report.md,
  specs/native-alarms/spec.md) were reconstructed into this archive folder via Read-verified
  Write calls, preserving full content. The original `openspec/changes/alarm-volume-ramp-restore/`
  folder was NOT deleted and still exists alongside this archive copy — a human or an agent with
  shell access must remove it to complete the move (see archive-report.md "Archive Integrity").
