S00-005: Record blocked task and remediation handoff

Changes: Preserve incomplete work and blocker metadata for S00-005. This checkpoint does not mark implementation accepted.
Validation: Session ended with status blocked.
Blocker: Previous runner session was interrupted before submit/escalate; processes stopped. User now explicitly requests resuming development. Preserve partial artifacts, verify them in a fresh bounded remediation, and return original to a new executor only after independent review.

Task: S00-005
Agent: auto-storage-88c3286c6641
Role: storage
Action: claim
Status: blocked

Task title: Выбрать IndexedDB wrapper и migration policy

+## Шаги
+
+1. Прочитать blocker report и handoff.
+2. Воспроизвести конкретную причину.
+3. Исправить только локальную причину в scope или уточнить внешний input.
+4. Выполнить focused проверку и submit.
+
+## Приёмка
+
+1. Причина воспроизводимо устранена.
+2. Исходная задача не завершена обходом требований.
+
+## Focused checks
+
+1. Повторить сценарий прерывания.
+2. Проверить отсутствие изменений вне scope.
+
+## Блокер и завершение запуска
+
+Для всех ролей scope — только эта задача. При блокере создать issue JSON по state/ISSUE_TEMPLATE.json, вызвать escalate с текущим ID/role/agent, проверить status=blocked и resolution_task, затем немедленно завершить запуск. Не решать blocker и не выбирать следующую задачу самому. Новый агент назначается runner. Правки metadata через CLI — единственное исключение scope.
+
+## Передача
+
+Сохранить evidence/handoff; submit → review и завершить запуск. Reviewer также выполняет только эту задачу, включая обязательное escalate при блокере.

+See original handoff and task evidence.

+Original: S00-005; reporter: auto-storage-88c3286c6641; resolution: S00-023.
+
+Previous runner session was interrupted before submit/escalate; processes stopped. User now explicitly requests resuming development. Preserve partial artifacts, verify them in a fresh bounded remediation, and return original to a new executor only after independent review.
+
+Next: complete and review the remediation; only a fresh session may continue.
