Three test files covering the Phase 1 invariants:
- derivePulseStatus: draft/closed are sticky; open auto-closes by date.
- vote UNIQUE(pulse_id, user_id): castVote (OR IGNORE) keeps the first vote
silently, a raw second INSERT raises a constraint error, and uniqueness is
per-pulse (same user on a different pulse is fine).
- homeRouteForRole: cab/fenja → /pulse, pilot → null (render existing home).
tests/setup.ts opens BIFROST_DB_PATH=':memory:' and applies all migrations
before tests run, so the in-memory DB has the live schema. Each vitest fork
gets its own globalThis → its own fresh in-memory DB.
The homeRouteForRole helper extraction makes the / role-redirect testable
without booting Astro. Step 6 will use it from /index.astro.
