description	Keep tests deterministic and Effect-aware. Use when lint flags direct vitest imports or conditional assertions inside tests.

Use @effect/vitest for tests in this repo.

Fix Shape

• Import describe, it, expect, and helpers from @effect/vitest.
• Import utility helpers from @effect/vitest/utils when needed.
• Do not import from raw vitest except in config or tooling files.
• Do not put expect(...) behind if, ternary, logical, or switch branches.
• Split conditional behavior into separate tests, or assert the branch condition and expected value explicitly.

Bad

if (result.ok) {
  expect(result.value).toBe("x");
}

Good

expect(result).toEqual({ ok: true, value: "x" });
