 ## Hard rules
 
 - No em-dashes in user-facing copy or code comments. Use hyphens, commas, or restructure. En-dashes only in numeric ranges like "13-24 months".
 - When computing what-if or recommendation point gains, simulate by re-running the score function on modified copies of the input. Never hardcode point deltas.
-- Run `npm run typecheck` and `npm test` before finishing any change.
