Canonicalize stable feature provenance during same-version prerelease merges

Ensure same-version stable and prerelease AEM SDK/add-on feature merges keep the final feature identity and provenance anchored to the stable artifact while retaining prerelease precedence for merged content values.

Start by locating the Maven plugin entry point that merges same-version AEM SDK or add-on features, then trace how feature identity, provenance, and merged content values are selected. Verify cases combining stable and prerelease artifacts at the same version; done means the final identity and provenance use the stable artifact while prerelease content values retain precedence.
