- Split frame.go: extract built-in components to frame_components.go - Replace custom indexOf with strings.Index in frame_test.go - Make prompt.go testable: accept io.Reader via SetStdin, add tests - Decompose runGoQA: extract emitQAJSON and emitQASummary helpers - DRY: centralise loadConfig into cmd/config/cmd.go - Remove hardcoded MACOSX_DEPLOYMENT_TARGET from test/fuzz/cov commands - Add error assertions to coverage_test.go Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
