Code-quality reviewer flagged:
- R25 'malformed output' tests used .rejects.toThrow(/parse|invalid/i)
which could match unrelated errors. Replaced with
.rejects.toBeInstanceOf(ZodError) for both sign-in and sign-up.
- sign-in controller test asserted result.name only as truthy; the
parallel sign-up test was already precise (toBe('session')). Tightened
to match.
61 tests still passing for @repo/auth.
