Eval results record which mocks answered and why a run aborted

Under the hood
Useful1 Signal2
Plugin Eval

Eval results now list which stand-in servers answered and count calls nothing covered.

What

An eval result now includes a mocks block listing each stand-in server's kind and per-tool responder, defaulting to "fixed", plus a tally that counts calls the mocks did not cover as unmocked.

Details
  • A run that aborted, or whose mocks could not be prepared, returns a zero score carrying the server, tool and reason, plus any auth_rejected flag.
  • Mocked tools are announced per case and excluded from the check that a case exercises a real tool.
  • Mock call logs are read back into the result as call records and a tally.
  • A separate standalone eval config schema, covering schema version, graders and config overrides, was dropped from this part of the bundle.
Evidence

mocks: could not be prepared for this case, mockSetupFailure, "Mock stand-ins for MCP servers, from <eval dir>/mocks/ (record | off; default: record — off spawns the real servers, gated by --allow-tools as usual)"

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
