Description

We used to sanitize Bugzilla data manually to run evals for the build repair agent. Now it's using the MCP so that it can see the fixes in the historical dataset. There should be a way to limit Bugzilla comments to the ones before the fix.

Research direction

Start by tracing the MCP Bugzilla data path used by the build repair agent evaluation. Determine how the fix point is represented and where historical comments are selected, then verify that comments after the fix are excluded while earlier comments remain available.
