Gabriel Brown
44124d72fa
The audit's second tier: values that were measurements of the author's desktop, shipped to every machine as if they were defaults. Settings greeted every human as Gabriel; it now greets whoever accountsservice says is signed in, and nobody when it says nothing. The weather shipped his home coordinates and confidently reported his forecast anywhere on earth; it now ships unset, fetches nothing until a location is chosen, and the location row says so. The GTK bookmarks carried seven /home/gib paths and his file server into every file dialog; they are now generated per machine from a template and gitignored -- Nautilus edits the instance freely, the way settings.ini already worked one file over. Web search routed through his personal bang redirector; the engine is now the webSearchUrl preference with a DuckDuckGo default, read by both the script command and the suggestions extension, which the launcher-search contract already pins to one another. The GPU vitals path defaulted to his card1 and lost the readout on any machine enumerated differently; a machine with exactly one GPU now adopts it. And the Containers and Snapshots pages hide once a scan proves their backing stack absent, instead of rendering permanently empty on machines that never had podman or snapper. Lesser residue swept in the same pass: the DP-2 hyprpaper block one machine needed, the author's username-typo expansions (moved to his personal seed in user/, where personal content belongs), a capture fallback into /home/gib, and a parity table asserting one machine's hardware as fact.
