v2.1.25 ships Phase 3: diff-previewed, confidence-gated, reversible merge/supersede controls on a never-delete bitemporal store. It adds seven MCP tools for merge candidates, merge/supersede planning, apply, undo/reflog, protection, and policy; plus Migration V14 for merge plans, merge operations, protected memories, and superseded lineage.

Release assets are built by the Release workflow. Publish npm only after the platform archives and checksums are present, because the npm postinstall downloads from this GitHub release.
