(Overlaps the `janitor`'s spirit, applied to code.) +- **DEFER** — worth doing but **blocked**: no test net yet, or larger than a quick fix. Route to + `ROADMAP.md` with the precondition named (usually "characterization test first"). +- **ACCEPT** — real debt that is **not worth the risk**: low payoff, or HIGH risk-to-change for + modest gain.
