  "summary": "Static review of a published TypeScript type surface: `.d.ts` correctness and emit strategy, public-versus-accidental exports, breaking-change classification and the semver decision, the consumer compilation matrix, and compile-time type-contract tests. Reads declarations, API reports, and configuration only.",

  "security_notes": "Static review only — reads declaration files (`.d.ts`), API reports/rollups, `package.json`, consumer `tsconfig.json` files, and Vitest type-test source; never compiles, builds, runs, publishes, or executes the package, never contacts a live registry or consumer, and never requests secrets, credentials, registry tokens, or customer data. A breaking-change classification made without a supplied baseline surface is labelled inference, not confirmed.",
