This inventory is not a new license for the application's own source code.
The original repository has no established application-wide license. Before
redistributing this GPL-linked binary, the owner must resolve the application's
compatible licensing and corresponding-source obligations. The prepared local
ZIP is a test artifact, not a declaration that redistribution obligations have
been satisfied. The old installer license template is not used in this ZIP.
