Use a verified writable copy of pinned Python for uv builds. Keep the
signed launchers and bundled Python as the MSIX runtime so plugin
rebuilds do not remove package access.
Identify Microsoft Store builds from the artifact stamp. Use StoreContext
for update checks, downloads, and installation requests inside Hermes.
Keep relaunch and recovery ownership across the update. Do not report
unknown checks or no-op requests as successful installations.
Open the build commit link in the system browser.
Verification: 168 Python tests, 107 Electron tests, and 121 renderer tests
passed. Typechecks, lint, lock validation, and desktop builds passed.
A real packaged process completed plugin admission, import, and repair.
Store-acquired download, installation, and relaunch remain unverified.
This host has only the sideloaded MSIX. Its real Store API call returned
an error, which the app reports as unknown. macOS updates are unchanged.
