+
+fix(metadata-protocol): the metadata save door stores an action as its `ActionSchema` parse, so a declared `requiresFeature` / `requiresMembershipReach` is lowered into `visible`
+
+Clause-②: no — the save door refuses nothing it accepted before. It already judged the body by the same parse; what changes is only what it stores for an action that passed.
+
+Metadata-protocol: none
+
+`PUT /api/v1/meta/object/NAME` (draft and active) and a standalone `action` save judged an action by `ActionSchema`, then stored the request body as written. `ActionSchema`'s parse lowers `requiresMembershipReach` and `requiresFeature` into `visible`, and the console reads `visible` alone, so the stored action kept both gate keys raw, had no `visible`, and its button was offered to every user.
+
+Now the door stores the parse it already ran:
+
+- an object's own `actions` array is stored as the parsed array; every other key of the object body stays as written;
+- a standalone `action` item is stored as the parsed action.
+
+A stored action therefore carries the lowered `visible` (and its schema defaults, and a CEL shorthand wrapped in `{ dialect, source }`), the same shape a code package's action has been stored in since #25981. The parse is idempotent over its own output, so a GET then PUT round trip stores the same bytes.
+
+Rows already saved before this fix are not rewritten. Saving the object (or action) again stores it lowered.

+/**
+ * [#26723] The actions a metadata save stores, as their `ActionSchema` parse.
+ *
+ * The save door judges a body by its type's spec schema and then keeps the
+ * request body as written, with a few normalizations grafted back
+ * (`graftFoldedFormSections`, `graftNormalizedOperators`). For an action that
+ * dropped the one transform a reader depends on: `ActionSchema` lowers
+ * `requiresMembershipReach` and `requiresFeature` into `visible`, the console
+ * reads `visible` alone, and the stored body carried the two gate keys raw with
+ * no `visible`. The declared gate did nothing: the button was offered to every
+ * caller.
+ *
+ * So an action is stored as the parse the door already ran, the same parse the
+ * code-package registration door stores since #25981 (`parsePackageAction` in
+ * `@objectstack/objectql`'s registry). ⛔ No second copy of the lowering: the
+ * values here are the parse's own output, read off the `parsed` tree, never
+ * re-derived. The parse is idempotent over its own output, so a GET → PUT
+ * round trip of a stored body stores the same bytes.
+ *
+ * - `object`: its own `actions` array is replaced by the parsed array
+ *   (`ObjectSchema`'s `actions` is `ActionSchema[]`); every other key of the
+ *   body stays as written.
+ * - `action`: the body is the parsed action.
+ * - Any other type, or an object with no `actions` array, is returned as is.
