Subject: [PATCH] =?UTF-8?q?fix(ai-ops):=20HealLog=20DetachedInstanceError?=
 =?UTF-8?q?=20=E2=80=94=20refresh=20before=20expunge?=
MIME-Version: 1.0

SQLAlchemy expire_on_commit=True(預設) 會在 commit 後清空 ORM 屬性。
expunge 單獨使用仍會觸發 lazy-load → DetachedInstanceError。
修正：commit → refresh（重載屬性入記憶體）→ expunge（脫離 session）。
