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.
