Description 583 -> 231 chars and body 854 -> 519 words. Deletes the
neuledge-context boundary clause outright: commit 6146120 deleted that
skill and no skill has owned MCP-server installation since. That was the
last dangling routing target in the corpus.
Removes META.md, which file-structure.md:20 forbids at a skill root. Its
when: field duplicated the description and its references: entry pointed
at .agents/skills/context7-mcp/SKILL.md, which does not exist.
Restores two rules a clean-context audit found had lost their force: the
starting-URLs branch in step 3, which the retrofit had reduced to a
condition with no behaviour, and the references/file-format.md pointer at
step 6. The second matters downstream -- validate-provenance.sh parses
sources.md with anchored regexes and check 8 short-circuits silently when
the Status field is absent, so a sources.md written from step 6 alone
broke the provenance chain with no error anywhere.
Rewrites steps 4-5 as serial WebFetch reads. They mandated spawning
subagents that allowed-tools never granted; no tool was added because the
name differs across the three compile targets. Tracked as #116.
Updates the two test pins and the eval case that asserted the dead route.
Refs #99
tests/test-adr0020-targets.sh pinned the corpus dangling set as exactly
{gitea-labels, neuledge-context} and tests/test-skill-size-check.sh probed both
individually. The gitea-issues retrofit cut the composition sentence whose
'>'-folded scalar produced 'gitea-labels- milestones', so that target no longer
exists and both suites went red.
EXPECTED_DANGLING is now {neuledge-context} and the gitea-issues probe is
removed rather than skipped, per the rule the probe file states about itself: a
probe whose fixture has been retrofitted is a pin that needs updating, not an
assertion-free pass counted in the totals.
The exact-set assertion stays. An empty expected set is still valid and still
pins that no new dangling target appeared -- which is what it becomes once
research is retrofitted. Both loops carry a shellcheck SC2043 waiver for the
same reason: one entry is the expected steady state, not bad quoting.

A prose-form routing target blocks a commit only when its own sentence names
another target that resolves. That makes the sentence splitter part of the
ADR-0020 contract rather than an implementation detail, and the naive
"period, space, capital" rule got it wrong in both directions:
- OVER-SPLIT: `e.g. "..."` is not a sentence end, but the quote looks like a
start. The clause was cut in half and the corroborator stranded on the far
side, so a genuinely dangling target silently demoted to SUGGESTION — a
measurement taken and then discarded, the vacuous-green shape this gate
exists to prevent. Seven such splits are live in the current corpus.
- UNDER-SPLIT: a sentence opening with a code span or a lowercase skill name
was not seen as a start, so two sentences merged and a resolving target
vouched for an unresolvable one it never stood beside — a hard FAIL with no
escape hatch, which is the exact failure corroboration was added to prevent.
The splitter now excludes the five abbreviations that occur in routing prose
and admits a backtick or lowercase letter as a sentence opener. Applied
byte-identically to all three copies of the shared resolver.
Verified zero-delta against the corpus: 37 ERROR / 58 SUGGESTION / 2 dangling
before and after, findings byte-identical. The exposure this closes is to the
descriptions #99 is about to rewrite, not to the ones already measured — which
is why the deferral reason recorded on PR #103 ("can move the documented corpus
counts") does not hold and the fix lands here rather than after the retrofit.
Three regression tests, one per direction plus the backtick opener, each proven
non-vacuous by reverting the splitter alone and watching it go red.

Every defect fixed in f7cc279 was reachable because nothing asserted against it.
The gate had 43 assertions and none of them covered a consumer repo, a non-string
description, an unclosed fence, or the two spec ceilings. Each case below fails
against the pre-fix code and passes against the current one; every one was proved
non-vacuous by mutating a scratch copy of the script and watching the test go red,
independently twice.
The two that mattered most had no fixture anywhere. A consumer repo WITH .git is
the shape the resolver exists to serve, and only the no-.git case had ever been
tested, which is exactly why the blocker was invisible. And ADR-0020 says the
walk-up runs in two passes specifically so a nested .git cannot beat a plugins/
root further up — no fixture had ever placed a .git inside a plugin.
test-adr0020-differential.sh loses _non_adr_hook_error(). It excluded MAX_LINES and
MAX_WORDS from the cross-script comparison on the untested assumption that awk and
splitlines() agree. They do not, and the divergence stayed invisible for exactly as
long as the exclusion stood. The ceilings are now compared like any other rule.
Two existing assertions were repairs, not additions. The skill-improve probe had
been fixed by this very branch, so its iteration permanently took an
assertion-free SKIP that still counted as a pass; both branches now fail loudly and
each names the other file's pin so the two stay in step. And the yaml-none fixture
emitted `---/---`, which never matched the frontmatter pattern at all — it passed on
the bare word "frontmatter", present in both messages, while never reaching the
branch it was named for. Needles throughout that file now name their branch.

Three ways the gates could report green having measured nothing. All three were
invisible to a passing test suite, because pre-commit prints nothing at all for a
hook that exits 0 — a gate that declines to check and a gate that checked and
passed produce the identical signal.
- A UTF-8 BOM, a leading blank line, a trailing space after a `---` marker or
CRLF line endings defeated the `^---\n` frontmatter matcher. Every ADR-0020
check was then skipped and the file passed: measured at the time, a
550-character description with a 1,000-word body exited 0 behind a BOM.
All four shapes are now tolerated, and frontmatter that genuinely cannot be
parsed is a hard ERROR rather than a silent skip.
- An agent file with a valueless `description:` followed by another key let a
line regex capture the *next* key, which looked non-empty, so the
missing-or-empty branch never fired and every gate below it early-returned on
the empty folded value — zero output, exit 0, on a blocking gate. The one
field this contract is entirely about was the one field a gate could fail to
notice was absent. Presence is now decided on the YAML-folded value and
nowhere else, and a missing or empty description is a hard FAIL in all three
validators.
- The hand-rolled frontmatter fallback disagreed with PyYAML across the FAIL
boundary on folded scalars, so which reader happened to be available decided
the verdict. A fallback that mis-parses a scalar shape reports a vacuous pass,
which is worse than not running, so it is deleted: python3 and PyYAML are hard
requirements that fail loudly with an install pointer.
Boundary-target resolution no longer derives its universe from its own location.
A `${BASH_SOURCE}`-relative repo root leaked this repo's 39-skill universe into
every consumer repo running the hook through pre-commit, so a consumer skill
routing to `skill-audit` resolved against a plugin it had never installed. The
interim form resolved through `.claude/` and `.agents/`, which are gitignored
`apm install` output — the same commit reported 2 dangling targets on a machine
that had run the install and 6 on a fresh clone. Resolution now walks up from the
file being checked to an authoring root (nearest ancestor holding
`plugins/*/.apm/{skills,agents}`, else the nearest `.git`, in two passes so a
nested `.git` cannot outrank a real monorepo root); the universe is every skill
and agent under `<root>/plugins/*/` plus the file's own apm package and that
package's declared `dependencies.apm`. Deployed trees are consulted only when no
authoring root exists at all — the consumer case. One commit now gets one verdict,
which a gate shipping hot with no baseline file has to.
Narrowed in the same pass: a routing target inferred from the prose boundary form
and corroborated by nothing else reports at SUGGESTION instead of blocking. A
blocking check with no escape hatch is the wrong trade when the inference from
prose is the weak part of it.
New deterministic checks, all previously untested or absent: every
`references/<file>.md` a body names must exist (ERROR — a broken pointer is not a
style opinion); a description with no boundary clause at all, a Gotchas section
over five entries, and a Gotchas section over 25% of the body are SUGGESTIONs.
Where no universe can be determined the target check prints `INFO ... DID NOT
RUN` rather than passing quietly. Each prose-scanning check needed its own
false-positive fix — a fenced example of a Gotchas section was being read as the
section itself — and those fixes are pinned rather than assumed.
The resolver is one block copied verbatim into all three scripts between
BEGIN/END markers, because a cache-installed plugin's scripts cannot read outside
their own plugin directory. Nothing asserted the copies were still identical; a
one-line edit to a single copy passed every constant-agreement assertion, since
constants are not what drifts.
Tests land here rather than in a later commit. The existing suites assert the old
behaviour and go red against these scripts, so splitting them would leave a commit
whose own `run-tests` pre-push gate fails in isolation.
