Vale locates a frontmatter description by matching the parsed YAML value back
against the source text, so any scalar whose value is not spelled out verbatim
loses the `text.frontmatter.description` scope entirely. The wrapper only
flattened `>` folded scalars, so plain, double-quoted and single-quoted
multi-line descriptions silently reported zero alerts and exit 0 — a clean pass
indistinguishable from a real one, in a prefilter whose callers are instructed
not to re-derive its verdict by judgment.
Implementation notes:
- Classify the scalar kind after `^description:[ \t]*` and reuse one shared
continuation-line generator for every form; `|` literal blocks keep their
line breaks, stay verbatim-matchable, and are still left untouched.
- Emit the flattened value in whichever scalar form needs no escape at all
(plain, then single-quoted, then double-quoted), because any escape breaks
the verbatim match. The old blanket `'` -> U+2019 substitution silently made
apostrophe-bearing rule tokens unmatchable across 63% of the corpus; it now
survives only for the one combination no YAML scalar can carry verbatim.
- Terminate continuations at a line flush with the key, not only on a shallower
indent — a `description:` followed by a flush-left line previously swallowed
the rest of the frontmatter.
- Route vale's value-taking flags explicitly instead of inferring targets by
file existence, and absolutize relative `--output`/`--path` values the way
`--config` already was, since the run `cd`s into the scratch mirror.
- Fail loudly on a nonexistent path instead of inheriting bare vale's fallback
to stdin, which rendered a typo'd path as `0 errors ... in stdin`, exit 0 —
a form the callers' `0 files` NOT-RUN guard cannot match.
- Follow symlinks when walking a directory argument, matching bare vale.

Under set -u, "${arr[@]}" on an empty array aborts on bash before 4.4,
which is what macOS ships as /bin/bash. Three expansion sites now use
${arr[@]+"${arr[@]}"} consistently.
The hazard is not currently reachable: verified on a bash 3.2.57 built
from source that all seven invocation shapes succeed against the
previous code, including zero args, flags-only and an empty directory.
vale_args is provably non-empty at every site because the default
--config branch always appends first. The guard is kept because that
invariant is non-local and untested, so an edit to the default-config
branch would reintroduce a macOS-only crash silently.
Test fidelity is deliberately mixed. Case 16 is static and is the only
one that fails against the previous code, since no bash 5 host can
reproduce the abort at runtime. Case 17 runs the emptiest invocations
under the oldest bash it can find and names that shell in its output
so it cannot overclaim. Case 18 guards against the tempting wrong fix
of dropping the quotes, which also silences the abort but word-splits
a path containing a space.
No other bash 4.x construct is present; swept for mapfile, declare -A,
case modification, negative indices, globstar, wait -n and namerefs.

pre-commit prefixes only entry[0] with the hook-repo clone path
(cmd = (prefix.path(cmd[0]), *cmd[1:])), so the --config argument in
.pre-commit-hooks.yaml resolved against the *consuming* repo's root
and hard-failed every external run with E100. Two of the three hooks
ADR-0014 promises were unusable.
vale-wrap.sh now self-locates its config from BASH_SOURCE when no
--config is supplied; an explicit --config still wins in all three
argv forms and stays cwd-relative. Both manifests drop the argument
and are kept byte-identical: the local repo: local config resolved
--config correctly only because the consuming repo *was* this repo,
and that divergence is why three review rounds missed the defect.
Also in the wrapper:
- replace GNU-only `realpath -m` with a portable abspath helper; -m is
load-bearing (dest does not exist yet), so BSD realpath aborted the
script under set -e on macOS
- walk directory arguments instead of passing them through unflattened,
which reported a clean 0-error run for files that fail when named
explicitly
- read/write with errors='surrogateescape' so one non-UTF-8 .md under a
directory argument cannot abort the hook
New test-vale-hooks-consumer.sh builds the hook repo from the working
tree and points a file:// consumer at it, covering the manifest as a
hook repo for the first time.

skill-audit/agent-audit's Step 1 resolved vale-wrap.sh/.vale.ini via
`git rev-parse --show-toplevel`, which returns whichever repo the skill
happens to run in. Inside ai-development that works; in any external repo
that installs kyberforge@holocron as a plugin, it resolves to that repo's
own root, which has no .vale.ini — the prefilter silently fell back to
full LLM judgment. ADR-0013 named this as a deliberately deferred gap.
Vale's config/styles/wrapper now ship inside the plugin itself: a
canonical copy in agent-audit/assets/vale/ (Kyberforge + KyberforgeCopilot,
the superset agent-audit needs) and a smaller duplicate in
skill-audit/assets/vale/ (Kyberforge only) — per the no-cross-skill-path
rule already established for plugin cache-installs. Both skills resolve
these relative to their own directory, same as scripts/validate.sh
already does.
A new root .pre-commit-hooks.yaml exposes both copies plus
skill-size-check so any external repo can enforce the same rules via
`repo: <this-repo-url>, rev: <tag>` in its own pre-commit config,
independent of Claude Code entirely — the same mechanism covers CI. This
repo's own pre-commit hook now consumes the identical plugin-bundled
copies via repo: local (not a third root copy, and not a pinned
self-reference, which would lint working-tree edits against the last
tagged release instead of the change being made). Split into
vale-audit-prefilter-skill/-agent hooks after confirming, by diffing the
full corpus against both old and new config before deleting the old
files, that one combined hook pointed at only one copy silently 0-file-
skips the other file type.
scripts/check-vale-style-sync.sh guards the two copies against drift,
wired at pre-push alongside check-manifests.
