ASKAP J1745-5051
A long-period-transient comparison source spectroscopically confirmed as an accreting cataclysmic variable. Night Watch keeps it as a resolved control because it demonstrates how a strange periodic radio/X-ray record can move from open anomaly to ordinary compact-binary interpretation.

Ordinary-source checks
- spectroscopy supports accreting cataclysmic-variable interpretation
- retained as a resolved control for long-period transient review
- public record demonstrates why source-class restraint is required
Release limits
- included as a resolved comparison case
- public packet summarizes source literature rather than raw follow-up data
- no unresolved-origin claim is attached to this entry
