  Phase A (Alarms, work unit 1): COMPLETE - 23/23 tasks [x]
  Phase B (Custom Stations, work unit 2): COMPLETE - 17/17 tasks [x]
  Phase C (Equalizer, work unit 3): COMPLETE - 17/17 tasks [x]
  Phase D (Final Sweep): 3/4 tasks [x] (D4 optional on-device/emulator sanity check — no device
    available in this environment; every behavior is already Dart-testable and covered by the
    automated gate; explicitly skippable per its own task text)

notes: |
  New shared helper lib/servicios/persistencia_tolerante.dart introduced (parseListaTolerante,
  parseMapaTolerante, registrarSaltoPersistencia) — shared per-entry tolerant-parse primitive
  across all 3 subsystems (D1).

  W1 (archivoCustom() path resolution left outside the IO try/catch in
  lib/estado/estado_radio.dart) was identified during verification and FIXED post-verify by the
  orchestrator (commit 316e9a7/48e74e6): the resolution call is now wrapped in its own try/catch
  inside _cargarEmisorasCustom(), setting _customDegradado=true and logging via
  registrarSaltoPersistencia on failure instead of throwing uncaught into
  EstadoRadio._init()'s Future.wait(...). A RED-GREEN regression test was added. Full targeted
  gate re-run: 53/53 green across the 4 persistence suites touched by the fix. Independently
  confirmed present in source at archive time via direct read of
  lib/estado/estado_radio.dart (_cargarEmisorasCustom/_archivoCustom). W1 is CLOSED.

  W2 (multi-batch apply-progress "TDD Cycle Evidence" table only carries a row for the final
  batch, Phase A/B evidence lives inline in tasks.md instead of the consolidated table) is
  accepted as a documented, non-blocking process/tooling gap — independently corroborated via
  source-diff inspection and full regression re-run, not an actual RED/GREEN discipline failure.

  D4 (optional on-device/emulator sanity check) intentionally left unchecked — no device/emulator
  available in this environment; every behavior in this change is already Dart-testable and
  covered by the 62/62 automated gate.

  ARCHIVE TOOLING NOTE: this archive run had access only to Read/Write/Edit/Glob/Engram tools
  (no Bash/shell/delete-capable tool in this execution context). All 6 artifacts were copied via
  exact-content Read followed by verbatim Write (fidelity spot-checked against source, including
  a full tail-line match on the two longest files and a unicode-heavy table section) rather than
  via Bash `cp`. The original openspec/changes/persistence-corruption-guard/ source folder could
  NOT be deleted (no delete-capable tool available) — see archive-report.md "Archive Integrity"
  for the follow-up action required to complete the true move.
