+ * [#25467 cut 32] A stored commit row's `items` column read back as its revert
+ * plan, from `ObjectStackProtocolImplementation`, moved out of `protocol.ts`
+ * whole: `parseCommitItems`, which `listCommits` and `revertCommit` call. An
+ * array is the plan as stored; a string is parsed as JSON; anything else, or a
+ * string that is not a JSON array, reads as no items.
+ *
+ * A MOVE, not a redesign. The function below is the body of the
+ * `ObjectStackProtocolImplementation` method of the same name as it stood,
+ * re-indented one level and otherwise unedited.
+ *
+ * ## How the moved body reaches the class
+ *
+ * The shape #23050 set for `rest-server.ts` (its `data-action-routes.ts`
+ * header carries the full reasoning), as `protocol-batch-data.ts` applies it.
+ * The class keeps the method — the published `dist/*.d.ts` lists its name
+ * and declared signature. The body reads no class member, so the method's
+ * body calls the plain function, with no host. Every caller keeps calling the
+ * class method.
+ *
+ * The plan item type is `protocol.ts`'s own, and is imported from there as a
+ * type. Nothing re-exports this module, so the published surface does not
+ * move.
