Reviewed implementation boundary: Rollback records a marker; mount descriptions and governance metadata alone do not execute mounting or enforce signature authorization. Operations can have separate metadata/blob failure points. See /libraries/locus/overview.

This reference follows declared source modules, retains conditional attributes, and includes public declarations and implementation methods. Private-module re-exports and trait resolution require the compiler; this is a source reference, not a claim that every listed item is a root import. Function bodies and constant values are omitted.
