utils/file_length/config.py
Krzysztof kuhy Rudnicki 085d08b5c9 Split the two shell scripts and the gate's own config
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.
