  "// note": "Types are generated FROM JSDoc in the .js sources — bareguard ships as plain ESM JS. `npm run build:types` emits .d.ts into ./types (mirroring src/); `npm run typecheck` runs this single project. Both ./types and src/**/*.d.ts are git-ignored and built via the `prepublishOnly` script. Full `strict` is off because the hand-written JS throws ~130 strict errors that don't affect the emitted public types — but `strictNullChecks` IS on: it catches real null-safety bugs in the sources (it surfaced ~45, several genuine) and is the strictness that actually matters for the emitted declarations. checkJs validates the JSDoc that drives those declarations.",
