// Phase 12 Plan 03 — Task 2 verification script for actions.ts additions.
//
// This project has no test runner configured (no `scripts.test` in package.json),
// and `.env.local`'s DATABASE_URL points at PRODUCTION (per project memory) — so
// this script does NOT execute any DB calls or server actions (server actions
// also require an Auth.js session, unavailable outside a request context). It
// typechecks against the real exports/types from
// src/app/admin/offers/actions.ts and documents the 9 expected behaviors from
// the plan's <behavior> block, for manual run against a dev DB later if desired.
//
// Run (manual, dev DB only, inside a request context with admin session):
//   npx tsx scripts/verify-12-03-actions.ts
