What
Server configs fetched from claude.ai now map two new upstream fields onto the local config, and the sanitizer strips more server-supplied blobs before anything is written to disk.
Details
discover_support and cached_discover_response map to discoverSupport and cachedDiscoverResponse.
Sanitization before writing config now removes cachedInitResponse, cachedDiscoverResponse, discoverSupport, eligible and ineligibleReason, on top of the existing tools and discoveryCache stripping, so these do not leak into user config files.
Evidence
cachedDiscoverResponse
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
