A fastforward lane for trivial refactors that skips the usual three-phase ceremony. When you just want to extract a function, add guard clauses, or pull out a composable without writing design docs, this checks three hard gates (behavior unchanged, scope under 100 lines, tests exist), asks for one confirmation, makes the change using named classic methods, runs tests, and reports back in one line. Falls back to full cs-refactor if anything gets complicated mid-flight. The discipline is in the gates, not the process. Best for "clean up this function" moments where the full scan/design/checklist workflow feels like overkill but you still want guardrails against scope creep and behavioral drift.
