Why

• Zayit's first Microsoft Store submission was rejected for a generic icon: the GraalVM AppX shipped electron-builder's sample logos (the Electron atom), because Nucleus never passed the appx { } logos to packageGraalvmAppX. Fixed in Nucleus (fix(plugin): the GraalVM AppX gets its logos, at every scale and target size NucleusFramework/Nucleus#894).
• A Store-installed GraalVM image also crashed at launch without jawt.dll next to the exe; fixed in Nucleus (feat(microsoft-store): Microsoft Store purchases, app license, trial and updates NucleusFramework/Nucleus#891).
• The AppX had no updates at all (the GitHub feed is not for it): the Store has them now, through the Microsoft Store API of feat(microsoft-store): Microsoft Store purchases, app license, trial and updates NucleusFramework/Nucleus#891.

What

• Nucleus 3.0.0-dev-202610312124, with the nucleus.microsoft-store module.
• StoreUpdates (framework/update/StoreUpdates.kt): a seam over MicrosoftStore.updates, used by AppUpdateService when the app runs as the Store's AppX (unless a feed is forced for QA). The GitHub feed path (NSIS, DMG/ZIP, Linux) is unchanged.
  • Check: the Store's major.minor.build.revision is read as major.minor.patch; MINOR/MAJOR keep the database warning.
  • Always a prompt, no pre-download: the Store installs behind its own dialog, Windows closes the app and relaunches it. Progress goes to the existing dialog and settings banner; declining the Store's dialog keeps the update available.
  • A mandatory update (Partner Center) opens the dialog at launch.
• AppX logo sources at 1024 px (desktopAppIcons/LinuxIcon.png for the app icon and the Store logo, padded 1024 / 1240×600 tiles): Nucleus now makes every scale-* and targetsize-* variant from them.

Verification

• StoreUpdatesTest (6): level from the Store's version, patch prompts without pre-download, mandatory opens the dialog, install progress, declined dialog, up to date and Store failure. The whole :SeforimApp:jvmTest passes; ktlintCheck and detekt pass.
• packageGraalvmAppX with the published Nucleus: the package carries Zayit's logos in 35 variants, resources.pri, jawt.dll and nucleus_msstore.dll.
• Not verified: an update from the Store itself, which needs a published listing with a newer version.
