First of the 16 untested fixes/lib libs. Measured 37/37 = 100.00% through lib/tests/run_all.sh, twice, the second run at --min 100 (exit 0), then removed from the allowlist and confirmed with the real gate and no exemption. Adds two reusable pieces rather than a per-family harness clone: - lib_test_core.sh -- PASS/FAIL tally, _t_eq/_t_contains/_t_lacks, a mktemp -d sandbox wiped on EXIT, a FAKE_BIN stub dir on PATH, and _t_stub/_t_unstub. _t_unstub runs `hash -r`: deleting a stub file alone does not drop bash's cached executable path, so the real binary would never be reached again. - bt_harness.sh -- sources the core, sources the real scripts/lib/common.sh for the production log_*/has_cmd helpers (verified inert at source time), and redefines _btctl and apply_fix verbatim from fix_bluetooth.sh, since those live in the entry script rather than in any lib. Same trade-off pacman_hook_stall_harness.sh already makes with log_size. pacman_hook_stall_harness.sh is deliberately left alone: its six libs are already off the allowlist, i.e. gated at 100% with no exemption, so refactoring it onto the new core would risk banked work for no gain. jscpd reads 1.6% against the hook's own flags, and **/lib/tests/** is excluded from that scan anyway, so the duplication budget is not at stake. _t_only_path exists because every tool these libs call (usbreset, pactl, lsusb, ...) genuinely exists on an Arch desktop: a prepended stub dir cannot exercise a "not installed" branch, so those cases drop PATH to FAKE_BIN alone. The three coverage runs were made in a detached worktree: a second session was writing to this repo concurrently, and the jail aborts on any working-tree delta during a run.
