427   * NOTE: runProposalsStage and regenerateProposals are not fully tested because they:
428   * 1. Call generateProposalVariants which makes real LLM API calls (costs money)
429   * 2. Require complex mocking that isn't supported in Node.js v20.20
430   *
431   * These functions are tested indirectly through:
432   * - Manual testing with real data
433   * - E2E tests that run the full pipeline
434   * - The database query logic tests above verify correctness
435   *
436   * The critical business logic (SQL queries, filtering, stats) is covered by these tests.
