Ten state-mutating sites across seven scripts wrote through a predictable, world-writable temp path (`/tmp/state.json`, `/tmp/system-state.json`) before the atomic `sudo mv`. Because the `>` redirect runs as the invoking user (sudo doesn't cover redirects), the shared fixed path is a symlink/ TOCTOU target and collides if two of these run concurrently. Switch each to a per-invocation `mktemp`; the atomic rename into place is unchanged. nomarchy-theme-set already used a temp var for its home-state write — this makes its system-state write consistent and cleans the temp up on failure.
