+feat(spec): the package export manifest declares `withheldMaps`, the maps it withheld whole, and an unmanaged import accepts it
+
+Clause-②: yes (widening)
+Metadata-protocol: added
+
+`GET /packages/:id/export` writes each item as a served read returns it, so a connector's header and environment-variable maps are already withheld whole by the connector redactor and the exported item simply lacks them. An import elsewhere could not tell such a map from one the package never had. The export contract now has a place to say so:
+
+- **`PackageExportManifestSchema` gains an optional fixed key `withheldMaps`**, a list of `{ type, name, path }`: `type` is `connector`, `name` is the connector item's name, and `path` is one of the four positions the redactor withholds whole, spelled as it reports them: `providerConfig.headers`, `providerConfig.defaultHeaders`, `providerConfig.transport.headers`, `providerConfig.transport.env`. Positions only: no header or variable name is listed, and an entry carrying any other key is refused. It is declared ahead of its producer: no export writes it and no install door reads it yet, and its describe opens `[PLANNED — not yet served]` until the runtime half serves it. Until then, an export's lack of the key says nothing about what was withheld.
+- **`UNMANAGED_INSTALL_KEY_DISPOSITIONS` classifies `withheldMaps` as `door`**, so an unmanaged import accepts an export that carries it instead of refusing the whole package for an unrecognised key. The runtime half has the door read it to name each incomplete map; the new base never carries it.
+- **The export's `label` is classified `door` too.** The export contract has always declared it, but the table never classified it, so an unmanaged import refused any export that carried one. The base's install manifest declares no `label`, so the base is named by the request's `targetName` or the source `name`, as before.
+
+The table's totality test now reads the export's fixed keys as a third schema a package body is read with, beside `ManifestSchema` and the stack definition, so a fixed key the export gains reddens a spec test on the PR that adds it.
