Second of the 16 untested fixes/lib libs. 65/65 = 100.00% through
run_all.sh, twice, the second at --min 100 (exit 0), then cleared from the
allowlist and confirmed by the real gate with no exemption.
Two findings worth keeping:
- udevadm was NOT in the harness's stub list, so `udevadm control
--reload-rules` was reaching the REAL binary during the suite. A
prepended stub dir cannot hide a tool the host actually has. Caught by
asserting on the recorded call rather than by reading the code, which is
the argument for asserting on calls at all.
- _disable_usb_autosuspend writes /etc/udev/rules.d/50-bluetooth-no-
autosuspend.rules. Binding /etc in the jail would have covered it, and
was rejected: run_all.sh runs UN-jailed in ci_mirror.sh and in the
shell-tests workflow, as its own header says, so a bind mount protects
the coverage run and leaves every bare run writing to a real root-owned
file. Instead the lib gained a UDEV_RULES_DIR override, defaulting to the
real path -- the same env-override seam pacman_hook_stall_harness.sh uses
for PACMAN_LOG/CACHE_DIR/PACMAN_LOCK.
Proof the suite is safe where it runs un-jailed: after a bare run_all.sh,
the real rule file still has its 2026-02-21 mtime (it is a genuine artifact
of a production run six months ago) and the probed power/control values are
unchanged. The jail cannot give that check.
fix_usb_autosuspend globs the real /sys/bus/usb/devices/*/ with no override,
so its branches are driven through stubbed lsusb output: ffff:ffff matches
nothing on any machine and reaches the not-found arm, while 046d:c077
(control=on) and 046d:0825 (control=auto) are read-only probes, each guarded
so the case self-skips with a note if the host state changes rather than
silently asserting nothing.
Split across two test files to stay under the 250-line cap; run_all.sh globs
test_*.sh, so splitting costs nothing.

Four libs written in one pass rather than four sequential splits, which
is what stops the libs chaining - the entry gets one source block naming
all four and no lib sources a sibling.
steam_compatibility.sh is reverted and stays at 663. Its CACHE_MAP
associative array is declared and filled in what would be the ProtonDB
lib but read by main, so that lib fails SC2034 linted alone. Third file
deferred for the same reason: shared mutable state means the seam is not
there.
