+# Regression test for ZUPT GUI branding + licensing.
 #
-# History: in v3.0.0 the GUI shipped with two real bugs:
-#   1. An MIT license credit line in the about panel — the GUI is
-#      AGPL-3.0-or-later with commercial dual-licensing; "MIT" was
-#      false and inherited from an early templating mistake.
+# History: in v3.0.0 the GUI shipped with two documentation/code bugs:
+#   1. The about panel described the current GUI simply as MIT even though the
+#      current source carried AGPL-3.0-or-later notices. Published earlier MIT
+#      grants remain valid for the exact historical material covered by them.
 #   2. A version-string parser using `replace("zupt ", "")` which
 #      matched the wrong substring after the v3.0.0 rename. The
 #      version banner became `vaptvupt 3.0.0 (formerly zupt;
 #      renamed in v3.0.0 — INPI Brasil trademark)` and that
 #      `replace` chewed up "zupt " inside the parenthetical too.
 #
-# This test asserts both classes of bug stay fixed.
+# This test keeps the current about-panel statement aligned with current SPDX
+# notices without denying the historical license record, and covers the parser.
