 ### Fixed
 
+- Fix stable `Update-NovaModuleVersion` / `% nova bump` prerelease planning so existing prerelease versions finalize
+  their current semantic core before any later semantic bump is considered.
+    - `nova bump --what-if` now plans `2.0.0-preview01 -> 2.0.0` instead of `2.1.0` when commit history resolves to a
+      `Minor` label.
 - Fix `Invoke-NovaBuild` help discovery so it only scans `docs/<ProjectName>/` for PlatyPS
   markdown.
     - Regular markdown elsewhere under `docs/` no longer breaks the help-generation step.

 Use `-ContinuousIntegration` when the same session should first re-activate the built `dist/` module before the version
 bump workflow starts. This is useful in CI/self-hosting flows where an earlier command changed the active module state.
 
-When the current version is already a prerelease for the selected release line, Nova finalizes that same semantic
