 /**
- * Wave-0 RED stubs for the lists API router.
+ * Integration tests for the lists API router (LIST-01).
  *
- * These stubs cover LIST-01 through LIST-04 behavior.
- * Downstream plans (02/03/06) replace the `it.todo` entries with real assertions
- * once the routes and DB are wired.
+ * Uses the REAL dev MariaDB (not mocked) — same pattern as listAccess.test.ts.
+ * The global afterEach in test/setup.ts truncates list tables between tests.
  *
- * Security focus: T-04-02 — scoped fan-out (private list events must NOT reach non-owner).
+ * Run:
+ *   set -a; . ./.env 2>/dev/null; set +a
+ *   export DB_HOST=127.0.0.1 DB_PORT=3306
+ *   pnpm --filter @familysync/api exec vitest run tests/routes/lists.test.ts
  *
- * Run: pnpm --filter @familysync/api test
+ * Security focus:
+ *   - T-04-02: GET /api/lists MUST NOT return another member's private list
+ *   - T-04-05: DELETE/PATCH by non-owner/non-sharee → 403
+ *   - T-04-07: zod patchListSchema whitelists name/isShared only
+ *   - T-04-08: list_shares are server-managed only
