aur-publish/publish.sh 439 -> 148 + lib/aur_registration 107
+ lib/aur_verify 122 + lib/aur_publish_one 107
guard-lib/lib/file_guard.sh 350 -> 140 + file_guard_unlock 214
file_length/config.py 252 -> 45 + _tables 202 + exemptions 77
The libs are sourced, never executed: they read the readonly config the entry
script declares, and a `readonly` re-run inside a twice-sourced lib aborts
under `set -e`. Verified by function parity rather than by eye — publish.sh
resolves the same 17 functions as before the split, guardctl the same 15 —
plus `shellcheck -x` clean on every file and a real `--help` / bad-option run.
file_length is the gate's own code, so a broken import there turns the gate
into a no-op. Split three ways to avoid an import cycle without a `# noqa`:
_tables holds the data, exemptions the rules that read it, config re-exports
both so `from file_length.config import is_generated` still resolves. The
first attempt was wrong — EXCLUDED_DIRS was left behind and every invocation
raised — caught because the gate was re-run in both modes rather than
assumed. Now verified: exit 0 on a clean file, exit 1 on an over-cap one,
--explain intact, and the same 61 exemption decisions as HEAD.
Also deletes baseline-2026-08-14.json and SURVEY-2026-08-14.txt: the task
forbids a baseline file, and nothing in the tree read either.

Extracts the chattr+bind-mount+systemd-watcher file-locking pattern (and a
new pacman PreTransaction package-block primitive) out of screen-locker and
steam-backlog-enforcer into a standalone, config-driven library so both
projects (and steam-backlog-enforcer's new block-gaming feature) can share
one implementation instead of maintaining parallel copies.
- guardctl: CLI entry point (file-guard, package-block subcommands)
- lib/file_guard.sh: chattr +i / bind-mount / systemd-path-watcher / pacman
hook enforcement for a single target file, keyed by /etc/guard-lib/targets
config; includes `sync` (adopt current content as canonical - for a
caller's own legitimate edit) distinct from `pacman-relock` (revert drift)
- lib/package_block.sh: time-locked pacman PreTransaction hook that refuses
to (re)install a given package while a lock file's `until` timestamp is in
the future; supports --bind-mount to compose with file-guard on the same
lock file
- pacman-hooks/: the installed hook scripts + .hook definitions
- systemd/: guard-file@.path/.service watcher units, guard-bind-mount@.service
