 ### Added
 
 - **Corporate-memory tree view + cross-axis filtering** on `/corporate-memory` and `/corporate-memory/admin`. Operators choose a grouping axis (domain / category / tag / audience) and combine it with chip filters (status, source_type, audience, has-duplicate-hint, search). Tree uses native `<details>`; localStorage persists open/closed state per axis; no new dependencies. Issue #62.
