What
The evaluation and mocking system (used to test Claude Code against simulated MCP servers, which are external tools/data sources Claude can connect to) now supports marking a mocked server as withheld. A related internal function filters out withheld servers before deciding whether a test case actually ran without a given server dependency.
Why
This lets the eval harness distinguish a server that is deliberately left out of a test from one that's simply absent, so cases aren't miscounted as running "without" a server when that server was intentionally withheld.
