Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The change is mergeable, but successful test runs can leave behind a temporary fixture directory because cleanup handling is replaced later in the script; this is a bounded maintenance issue with no production impact and should be fixed or tracked.

Butane's own test suite validated every <!-- butane-config --> block in its docs. That check did not come across when Butane merged into this repository, so the YAML examples under butane/docs are unvalidated and a broken one would go unnoticed. Teach the docs validator to recognize Butane sections and translate them with butane/config, matching butane --check --strict. Butane's original loop drove csplit and head and skipped itself entirely when GNU coreutils were missing; going through the existing Go tool means the check always runs. Add the files-dir fixture that the local file references in the docs need, mirroring the one Butane's test created. Signed-off-by: Jason Colapietro <jasoncola1@gmail.com>

Summary
Butane's own test suite validated every
<!-- butane-config -->block in itsdocs. That check didn't come across when Butane merged into this repository, so
the YAML examples under
butane/docs/are currently unvalidated — a brokenexample would ship unnoticed. I ran into this while adding examples in #2302 and
had to check those blocks by hand.
This restores the coverage through the existing docs validator.
Why not port Butane's shell loop
Butane's version drove
csplitandhead, and skipped itself when GNUcoreutils weren't present:
That's a check that quietly does nothing on macOS, which is part of how the gap
went unnoticed.
internal/util/tools/docs/docs.goalready walks the docs for<!-- ignition -->blocks, so this extends it instead: it now also recognizes<!-- butane-config -->followed by a ```yaml fence and validates those withbutane/config.TranslateBytes, treating any report entry as fatal to match`butane --check --strict`. Ignition sections are handled exactly as before.
./testgains a step that creates the--files-dirfixture the docs'local:and
contents_local:references need — the same fixture Butane's test built.Testing
./test— Success, exit 0. The new step reports 76 Butane sections across6 files under
butane/docs/, all valid, so this goes green without needingany documentation fixes.
./ci/shellcheck—No error found with ShellCheck, exit 0No change for Ignition docs: output of the tool over
docs/isbyte-identical before and after this commit (10 and 19 sections, exit 0),
diffed directly.
The check actually catches things. Three negative cases, each exit 1:
nonsense_fieldnon-empty translation report ... unused key nonsense_fieldpathentriesfatal error translating ...: config generated was invalid```jsonfence after a Butane markerexpecting '```yaml', found: ```jsonexpecting '```yaml' after Butane marker, found end of fileunterminated Butane config sectionRunning the validator over
butane/docswithout-files-dirfails, whichconfirms the fixture is doing real work rather than masking errors.
The last two cases come from @coderabbitai's review:
findConfigSectionsused toreturn success when a file ended mid-section, so an unterminated block was
dropped without being validated. That behaviour predates this change — the
original
findJsonSectionsdid the same — but it is exactly the silent-skip thisPR exists to remove, so it is fixed here rather than left for later.
Note: this adds to the same release-notes list as #2302, so whichever lands
first, I'll rebase the other.
Happy to reshape this — a separate tool rather than extending the existing one,
or a faithful port of the old shell loop — if you'd prefer either.
