Features

• Compare full model fits inside a review. Model reviews now show goodness-of-fit deltas, a coefficient-shift table, and a feature-importance diff between the two model versions, bringing them to the same depth as dataset reviews.
• Build conditions by dragging them into place. Filter, partition, and custom factor dialogs let you reorder, regroup, and nest conditions by drag and drop.
• You can now view a model's effects as a geographic map, painting the selected column as a choropleth across each partition.

Improvements

• Editing on a protected branch now creates the branch inline from the same dialog, keeping you in one flow.
• Column distribution maps now include a Total panel alongside the per-partition panels.

Fixes

• The activity feed now refreshes after dataset edits and version transitions.
• Review change diffs show real object names, and the review detail page scrolls cleanly, shows breadcrumbs, and falls back gracefully when an author name is missing.
• Model-effect charts no longer get stuck loading when every effect is selected.
• Model configuration is locked while an automated feature build is running, preventing conflicting edits.
• Fixed MCP Server installation on signed macOS builds.
• Fixed a geography ingestion failure that occurred when the canonical file was missing.
