The clean provenance bill was an artifact. Checks 7 and 8 assume `Research doc:`
names a source index whose H2s are slugs, but 30 of 121 corpus entries point at
topic content documents whose H2s are topics. Those 30 produced every new check-7
INFO — all false positives. Check 8 aimed at the same documents, which carry no
`Status:` line at all, would have emitted a large false-FAIL flood; the only thing
preventing it was an unannounced `rd_status != extracted` skip. So "0 new FAILs"
rested on exactly the fail-open class this branch exists to remove, and naively
fixing the skip would have turned the branch red.
Checks 7/8 now run only when the research doc's basename is `sources.md`, and every
other case emits a visible INFO naming the slug. The dangling-path INFO stays ahead
of the basename gate, because a path that does not resolve is rot whatever it is
named. `parse_status` accepts the bullet form and a trailing note after the
backticked value, so a status it cannot read no longer reads as "nothing to check".
Corpus: 36 INFOs of which 30 were false, to 56 of which none are. FAIL stays 0, and
no Status line flipped to `extracted` under the new parser, so no FAIL was
suppressed by luck.
Also closed, each a silent pass: a nonexistent directory, a directory with no
SKILL.md, and extra arguments now exit 2; a UTF-8 BOM no longer defeats frontmatter
parsing; the bare `except Exception: return False` that turned an unreadable file
into a clean pass is gone, with all reads pinned to UTF-8; check 3 walks nested
`references/` subdirectories; `FILL IN:` at end of line no longer escapes checks 1
and 6; duplicate `## slug` blocks and repeated `Research doc:` lines are announced
rather than half-read.
The agent-audit copy carried all of the above unfixed and is now ported, minus the
four fixes that are genuinely N/A at agent scope — it reads a plugin-root
`sources.md` and has no checks 7/8 and no `references/` tree. Its silent exit 0 for
a file outside plugin scope is preserved deliberately: that is a verdict about a
valid file, not a skip, and `check-scope-walkup-sync.sh` pins it. Every exit-2 gate
therefore decides from the argument alone, before the walk-up runs.
`validation-scripts.md` said flatly that silence from the validator is a pass, not
a skip. That sentence is what made a typo'd path dangerous, and both copies are
corrected here. The matching SKILL.md exit-code guidance lands with the audit
rubric change, which touches the same files.
Tests: skill-audit 45 to 65, agent-audit 24 to 43, every new case proven by mutation.

The ADR-0020 body trim took `skill-audit` from 2,623 body words to a dispatch
shape, and two things went out with it that were not padding.
The manual structural fallback was one. Its replacement was a single sentence
telling the auditor to report an INFO when `validate.sh` cannot run — so with no
`python3` or no PyYAML, `skill-audit` reported the gap honestly and then audited
nothing structural at all. Every ADR-0020 measurement, the whole-file ceilings,
the name-to-directory match, the `references/` pointer check and the script
hygiene checks silently left the audit. A skill's whole Structure dimension
hanging on one optional interpreter is the same vacuous-pass shape the gate
scripts were just fixed for, one layer up.
The `E100 Runtime error ... does not exist` diagnostic was the other. That exit
code means an explicit relative `--config` was passed to `vale-wrap.sh` while
vale itself was installed and working; without the note, Step 1's fallback reads
exit 2 as "vale unavailable" and downgrades the description, body-discipline and
patterns dimensions to full LLM judgment for a config error it could have fixed.
That misreading is already recorded in CONTEXT.md as the reason both audit skills
stopped passing `--config` at all.
Both are restored in `references/validation-scripts.md`, loaded only when a Step 1
script fails — so the body pays nothing for them on a clean run, which is what the
dispatch pattern is for. The file also carries the by-hand boundary-target
procedure and the three ways to misread the result, including that
`INFO ... DID NOT RUN` is not a pass.
`references/file-structure.md` gains the one sanctioned spelling for a cross-skill
reference. The possessive form (``skill-audit's references/validation-scripts.md``)
is the only spelling both rules accept: a full repo path is what that section
already forbids, and a bare `references/<file>.md` is now a hard ERROR from the
ADR-0020 pointer check, which requires the file to exist in the skill's *own*
directory. Without the rule the two constraints look mutually exclusive.
