-The workspace ``config/latent.yaml`` enables all five library latents.
+The workspace ``config/latent.yaml`` enables every entry in

+three µJy variants (require ``magzero``, which the smoke fixture
+supplies), plus ``magnification`` and ``effective_einstein_radius``.
 The brackets are deliberately loose so PYAUTO_SMALL_DATASETS grid mutations
 (15x15) still yield passing values; the goal is a structural regression
 guard, not Bayesian validation.
