audit_axis_overlap
List every classified source that holds MORE THAN ONE value on a single-select classification axis (the stale-edge symptom a reclassification leaves when the prior same-axis edge is not retired). From 0.11.3 the classify writer supersedes by default, so this is the regression guard (a clean graph returns `overlaps: []`) and the detector for overlaps already in a graph. A `multi`-select axis is exempt; unaxed values are skipped. Titles resolve to entity names. Read-only.
Workspace & Portfoliosatomic (read-only). Reads the portfolio document only; never mutates.
