Spec deltas
Per-capability spec changes proposed by add-browser-collector-enrollment-primitive.
Device-exporter enrollment SHALL derive the enrolled binding's source kind from the connector manifest runtimerequirements.bindings rather than recording a fixed source kind. A filesystem binding SHALL enroll as localdevice. A browser binding (with no filesystem binding) SHALL enroll as browser_collector. A connector whose manifest declares neither binding, or for which no manifest is registered, SHALL be rejected with a typed error; enrollment SHALL NOT default to a source kind.
The reference connector-instance source binding SHALL support browsercollector as a source kind distinct from localdevice. A browsercollector binding SHALL identify a connector instance collected by a local collector that drives a browser session for a browser-bound connector. A localdevice binding SHALL continue to identify a filesystem-read local collection. This source kind is the connector-instance source-binding axis only; it is not the spine event source kind, and it is not promoted into PDPP Core protocol vocabulary.
