check_file_length.sh required a dot in the filename, so every
extensionless executable was silently uncapped. is_source_file() now
reads the first two bytes and accepts a shebang, which catches real
scripts while still skipping data files like i3/config.
That immediately surfaced boot_recovery/boot-repair at 756 lines --
three times the largest capped shell file in the repo, uncapped purely
because its name has no dot in it. Split along its own section markers
into lib/{discovery,repair_fs,repair_kernel,modes}.sh, leaving the entry
script at 218.
The report block stays inline on purpose. It is top-level code with exit
calls rather than function definitions, and sourcing it changed control
flow: 30 of 42 tests failed. That is recorded in the lib headers so the
next reader does not retry it.
No vmbox pass for this one, deliberately. boot-repair is UEFI/ESP tooling
and the guest is BIOS/GRUB, so a sandbox green would be actively
misleading -- the vmbox skill says so itself. The evidence is the fixture
suite, which drives the real script against synthetic root trees: 42
passed before, 42 passed after.
verify_shell_split.sh reports 31 of 32 functions byte-identical. The one
difference is clean_shadow_files, where quoting $ESP_MOUNTPOINT fixed a
genuine SC2086 that only became visible once the function left the
monolith -- shellcheck could no longer see the readonly declaration and
stopped assuming the expansion was safe.
lib/tests/run_all.sh delegates to that same suite rather than standing up
a second, weaker harness: these libraries need the entry script's strict
mode and globals, so testing them in isolation would test a fiction.

The shell-splitting work has been referring to check_file_length.sh --all
as its per-commit gate. No such script was ever committed: it is absent
from the working tree and from every commit in history, so each split so
far was checked by eye.
Cap is 250 lines, source extensions only (sh/bash/zsh, py, kt/kts, dart,
ts/tsx/js/jsx). Markdown, HTML, JSON, YAML and lockfiles are out of
scope, as are third_party/ and docs/superpowers/.
--all reports exactly 24 files over the cap, independently reproducing
the count the brief carried. That agreement is what confirms the
extension scope is the intended one.
Deliberately NOT wired into .pre-commit-config.yaml: 24 files are still
over, so a hook would block every commit. It becomes a hook once --all
exits 0.
