Impact

REQUIRED: Choose either Tooling Impact or Customer Impact (or both). At least one checkbox must be selected.

Tooling Impact

• Required tooling change
• Optional tooling change (include reasoning)

Required release tooling change that makes the static PDP the source of Store listing language, limits publishing-time substitutions to version values, removes obsolete AppStoreName mutation, and supplies the PDP root for StoreBroker's required media-root input.

Customer Impact

• Customer reported
• Found internally

Regression

REQUIRED: Check exactly one box.

• Yes
• No

This is not a regression.

Testing

The original change was validated through Store pipeline configuration review. For this release-branch backport, conflict markers were checked, the release-specific PDP path adaptation was reviewed in the staged diff, and git diff --check upstream/release/v7.4.21...HEAD passed. Full release pipeline validation is delegated to PR CI.

Risk

REQUIRED: Check exactly one box.

• High
• Medium
• Low

High risk because this changes Microsoft Store listing metadata and release-publishing pipeline behavior. Risk is constrained by preserving the release branch's existing PDP directory layout while applying only the original PR's Store metadata simplification.

Merge Conflicts

Conflicts in .pipelines/templates/package-store-package.yml and assets/AppxManifest.xml were caused by the release branch's singular .pipelines/store/PDP layout and older one-language manifest. Resolution preserved the release path, removed runtime AppStoreName mutation, reused the PDP root as the media root, removed the obsolete PDP-Media placeholder, and applied the localized manifest resource list.
