+
+Commit `083c9ac` was built from a clean tree into an Ubuntu 24.04 x86_64
+offline preview. Its outer checksum, internal manifest, exact Git source,
+complete no-index wheel install, entry points, and mock lifecycle all verified.
+
+On the same Ubuntu 24.04 graphical user, that archive then completed a real
+install, upgrade, uninstall, and final reinstall. The installed GTK settings
+entry point started under Xvfb. The exact active IBus engine remained
+`libpinyin`; the standalone voice service remained disabled and inactive
+because no new provider key was configured. A metadata-only digest of every
+entry below `~/.config/ibus/rime` was identical before and after the complete
+lifecycle. No API key, audio, transcript, vocabulary term, correction pair, or
+Rime file content was read or recorded.
+
+This strengthens the transition/install evidence but does not replace the
+fresh graphical Ubuntu VM gate above.
