Keep commit admission on the trusted workflow checkout and reject mixed
release inputs before loading repository code. Stage every built product
under its commit with receipt-bound summary links, never channel writes.
Build both Windows universal bundles through the existing SDK scripts.
Keep Store calendar versions separate from sideload app versions so zero-
major app versions remain packageable. Reject invalid arguments before
modifying bundles. Bind desktop and Termux versions to the source commit,
and record Termux cache provenance without labeling commits as tags.
Verification: 77 Python tests and 36 JS tests passed. Real makeappx packed
and unpacked disposable per-arch and universal packages. Seven official
workflow-expression checks, actionlint, syntax, lint and prose passed.
No signing, installed-app update, Android build, or remote dispatch ran.
