The fork takes its own name everywhere a user can see it: binaries (voculinux, voculinux-gui), desktop entry, autostart, tray, D-Bus namespace (com.voculinux.Voculinux, no alias for the old name), config/data/cache dirs, single-instance lock, IBus engine identity, tray icons, resource prefixes, VOCULINUX_* environment names, and the update-checker user agent. The internal Python module stays vocalinux and the distribution metadata keeps the upstream URLs as provenance. On first run a previous Vocalinux install's config.json, custom dictionary, and portal restore token are copied once into the new locations (new config always wins, no merge, no write-back); models re-resolve through the pinned-checksum download path. An offline naming-sweep test proves no old-name strings remain on user-visible surfaces outside the allowlist. Refs #18
