Be conservative about removal +Do not flag a file just because it is not production code. +Tests, migrations, routes, types, and integration glue can be necessary. +Only flag them when there is a concrete reason they are not needed for the stated change. + +4. Look for common redundancy patterns +- planning or brainstorm docs committed with product work +- local seed/pull/import scripts used only for one developer workflow +- generated files not required by the repo convention +- lockfile churn with no dependency intent +- support code added "just in case" without a real call path +- validation duplicated in multiple places without a trust-boundary reason +- broad refactors hidden inside a narrow feature PR + +5.
