The gate was a presence check -- 'a run_all.sh exists beside this lib' -- which an empty suite that asserts nothing satisfies. It now measures. 100% is reachable with no suppressions and no production source changes: run the suite inside a user+mount namespace and the sudo-writes, systemd units and nftables rules execute for real against a throwaway /etc. - meta/scripts/shell_coverage_jail.sh: the runner, promoted out of a session scratchpad. Two fixes it needed on the way: bind targets mirror the real directory tree (an empty bind makes writes fail with ENOENT, which reads as unreachable code), and sudo gets a pass-through stub because real sudo cannot setresuid inside a userns. - It fingerprints git status before and after and fails the run if a write escapes the jail. Verified with a deliberate escapee. - dot_resolver_install.sh: 39/39 = 100.00%, 28 assertions. Picked by scoring every allowlisted lib on root ops, system writes and destructive calls -- it scored highest in the repo. Allowlist 106 -> 105. - jscpd was already over its own threshold at 2.45% and would have rejected every commit staging a .sh file. Excluding vendored .venv/ shell alone gives 1.67%; also excluding lib/tests/ gives 1.47%. The gate is deliberately NOT wired into the hook chain yet.
