 ### Lint & Type Safety
 
 - Never land code that introduces new ESLint or TypeScript errors
-- Run `pnpm run lint` and `pnpm run type-check` before finalizing changes
+- Run `bun run lint` and `bun run type-check` before finalizing changes
 - Adding `eslint-disable` requires justification in a comment explaining why typing is impossible
 - Do **not** use `any` or `unknown` casts as escape hatches; build narrow adapter interfaces instead
 - Refactors or new features must keep existing lint/type baselines green
