// Case 2 row C2-13b (#1727): scripts/case2-install.sh installs a hub as <user>, and
// scripts/case2-precheck.sh's library checks and --library-status mode. Brief:
// docs/plans/2026-10-20_case2-rows.md "C2-13b". Every case runs in a scratch home with its own
// MOSAIC_CONFIG, a stub stack-copy and fake getent, sudo, id, node, bwrap and systemctl. The library
// sync runs in-process against a local bare repo, as the bus would. Nothing here reads or writes
// ~/.mosaic-dev, ~/.config/mosaic-dev, /etc or a network host, and no fixture value is a credential.
