Tools/Workspace & Portfolios/diff_classification

diff_classification

Show what MOVED on the competitive classification landscape: each competitor reclassification (from one classification_value to another on an axis) since a date. Reads the append-only reclassification history auto-recorded at the classify-write chokepoint, so "did AEM move from integrated to agentic" is one call instead of in-head reasoning. Returns transitions with resolved titles (competitor, from, to), sorted newest first. Pairs with `list_portfolio_cross_edges` freshness (which decides WHEN to re-assess); this surfaces WHAT changed. Empty when nothing moved or no history exists. Read-only.

Workspace & Portfoliosatomic (read-only). Reads the portfolio document only; never mutates.
