Subject: [PATCH] Expert benchmark framework + validation results
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

BugFixExpert: 5/5 = 100% (avg 3.2s, gemma3:4b)
TestGenExpert: 3/5 = 60% (codegen pipeline needs improvement for new file generation)

Known issue: Generator's "read original → generate modified" design
doesn't handle pure new-file creation well. Needs codegen-specific
generation path.
