function Resolve-BcAppFileIdentity {
    <#
    .SYNOPSIS
        Reads identity and test-app facts out of a built .app file.
 
    .DESCRIPTION
        Used to decide what a per-tenant publish should actually send to a customer environment, and to
        log WHICH app is being published rather than just a file name. An app counts as a test app when
        its manifest carries Target="Test" or it depends on a Microsoft test/assert library - the same
        rule the Marketplace submission uses to keep test apps out of AppSource
        (Resolve-BcMarketplaceAppSet). Test apps must never reach a customer tenant: they carry no
        business value, pull in the test framework, and can fail to install where it is absent.
 
        A file whose manifest cannot be read is reported with Readable = $false rather than throwing, and
        falls back to the FILE NAME for the test check. Refusing to publish it would be worse than the
        bug being fixed: a quirk in one artifact would silently turn a release into a no-op. So an
        unreadable file is still published (with a warning) unless its name marks it as a test app.
 
    .PARAMETER Path
        The .app file to inspect.
 
    .OUTPUTS
        PSCustomObject: File, Name, Publisher, Version, Id, IsTest, IsRuntime, Readable, Error.
