+`metaItemPackageBinding` is exported, and every `/meta` door that reads `?package=` reads it through that function, so `?package=all` names no package on the layered read, the list, the book tree and the diagnostics sweep

+Clause-②: yes (widening)

+- `metaItemPackageBinding(raw)` answers the package a request's `?package=` names, or `undefined` for `all` (the metadata list's "show everything" scope), the empty value or a non-string. The item read, the save and the publish already read `?package=` through it. The runtime dispatcher's `/meta` domain now reads it through the same function.
+- `GET /meta/:type/:name/layers?package=all` answered `404` for an item stored in a package, and now serves the layers that the read without `?package=` serves. The Studio editor sends this read when it is opened from the list's "show everything" scope.
+- `GET /meta/:type?package=all` answered `[]`, and now lists what `GET /meta/:type` lists: the items of every package and the env-local ones.
+- `GET /meta/book/:name/tree?package=all` served the empty implicit book of a package called `all`, and now resolves the declared book as the read without `?package=` does.
+- `GET /meta/diagnostics?package=all` swept nothing, and now sweeps what the plain sweep sweeps.
+- Unchanged: a real package id still scopes each of these reads. The item read's cache bypass still reads the raw parameter, so `?package=all` keeps the uncached read and its served `version`.

+The runtime dispatcher's `/meta` domain reads `?package=all` as naming no package, as `RestServer` does, so a `PUT ?package=all` through the `@objectstack/hono` catch-all no longer binds the row to a package called `all`
+
+Clause-②: no
+
+- The dispatcher's `PUT /meta/:type/:name?package=all` stored the row with `package_id: 'all'`. It now stores it env-local (`package_id` null), as `RestServer`'s `PUT` does.
+- Its layered read (`/meta/:type/:name/layers`), list (`/meta/:type`), book tree (`/meta/book/:name/tree`) and item read forwarded `all` to the store as a package id. The layered read answered `404` and the list `[]` for an item stored in a package. Each now answers `?package=all` as it answers the same request without `?package=`.
+- Every branch reads `?package=` through `metaItemPackageBinding` from `@objectstack/rest`, the function `RestServer`'s doors read it through.
+- Unchanged: a real package id still scopes each read and still binds a save.
