Tactical guidance for composing Permission Set Groups: layering permission sets, applying Mute Permission Sets to subtract narrow capabilities, sequencing the recalculation lifecycle, deletion order, and assignment-vs-activation lifecycle. Triggers: 'PSG composition', 'mute permission set', 'PSG recalculation', 'cannot delete permission set in PSG', 'PSG explosion', 'expired PSG assignment'. NOT for the strategic profile-vs-PSG choice or migrating off profiles - use admin/permission-set-architecture. NOT for record-sharing design (OWD, role hierarchy, sharing rules) - use admin/sharing-and-visibility.
