 - The eight TypeScript commits were replayed onto that merge without retaining obsolete stacked Next/React history. A range-diff confirmed that all eight logical commits remain.
 - The merged dual-React dependency graph exposed a missing `@types/react` edge in `recharts@2.15.3`. The same graph fails under TypeScript 5.6, so this is dependency resolution exposed by the rebase, not a TypeScript 6 language regression.
 - A package-scoped pnpm extension supplies the omitted peer only to `recharts@2.15.3`; a clean install links the React types into each Recharts virtual package.
-- Node 24.16.0 and pnpm 11.5.0 verification passes: frozen install, `check:all` (24/24 typechecks and 6/6 lint tasks), production build (21/21), test build (19/19), and Docs production build.

 - [x] Clean post-rebase checks exposed the missing Recharts-to-React-types dependency edge. A package-scoped pnpm extension fixes the graph; TypeScript 5.6 reproduction confirmed this is not a TypeScript 6 regression.
 - [x] Post-fix Node 24 verification passes: frozen install, `check:all` (24/24 typechecks and 6/6 lint tasks), production build (21/21), test build (19/19), and Docs build. Office Add-in has no diff from `v3`.
 - [x] TypeScript 7 feasibility tested in disposable trees. Direct replacement is blocked; the official TypeScript 7 CLI plus TypeScript 6 API compatibility pattern passes Prisma generation, Next type generation, production build, and all 24 post-build checks. Release-age policy and Docusaurus remain explicit prerequisites.
+- [x] Final rebase onto current `v3` commit `3872caee7` completed. Range-diff preserves all ten branch commits; the TypeScript wiki commit keeps the newer devcontainer timestamp and log history. Fresh Node 24 frozen install, `check:all` (24/24 and 6/6), and production build (21/21) pass.
