- Hide raw exception message in /register 500 path; log instead - Fail-closed (503) on email-verified DB check failure in login - verifyEmailToken throws if user row is missing instead of silently no-oping - Move sendVerificationEmail outside @Transactional in register so the outbound HTTP call only fires after the token row is committed
