docs(lint): correct the Vale exit-code and glob-scoping claims

cli-reference.md said vale exits non-zero for any alert at or above
MinAlertLevel. The exit code keys on error-level alerts alone;
MinAlertLevel filters display only. LESSONS.md records this exact
misconception as costing two review rounds, and this research doc is
the cited provenance source for the skills that state it correctly.

CONTEXT.md claimed a SKILL.md outside plugins/ matches no glob section.
[**/SKILL.md] matches any path ending in SKILL.md — the sentence is a
stale leftover from the path-scoped globs at cbc33d9, and contradicted
its own paragraph two sentences earlier. The NOT-RUN 0-files guard it
justifies is correct and is unchanged; only the rationale was wrong.
CONTEXT.md also cited the local files: regex as the scoping mechanism,
where the shipped manifest deliberately stays layout-agnostic.

ADR-0014 records the entry[0]-only prefixing constraint as the reason
the self-locating design is required, and that no entry may grow a
repo-internal path argument.

 ### Vale audit prefilter (skill-audit / agent-audit)
 Wiring Vale as a deterministic prefilter for `skill-audit`/`agent-audit`'s Description dimension (ADR motivation: issue #84) is repo-specific, not part of the generic `lint` plugin, so it doesn't live in `plugins/lint/` — but per ADR-0014 it also doesn't live at the repo root anymore. Two copies live inside `plugins/kyberforge/`, one per skill, since a plugin's cache-install only copies each skill's own files (no cross-skill sharing): `plugins/kyberforge/skills/agent-audit/assets/vale/` is canonical (`.vale.ini` plus a custom `Kyberforge` style covering description-opener banning ("This skill/agent..."), vague-capability wording ("helps with", "utilize", ...), and generic "see references/ for details" padding — and a `KyberforgeCopilot` style scoped only to `.agent.md` files for the Copilot-only "Use proactively has no effect" check), and `plugins/kyberforge/skills/skill-audit/assets/vale/` is a smaller duplicate (`Kyberforge` only, scoped to `SKILL.md`) kept in sync by `scripts/check-vale-style-sync.sh` (pre-push). A root-level `.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.yaml` — pre-commit clones the pinned rev into its own cache, independent of whether Claude Code or the `kyberforge` plugin is installed at all, and the same mechanism covers CI (`pre-commit run --all-files`). This repo's own `vale-audit-prefilter-skill`/`-agent` pre-commit hooks consume the identical plugin-bundled copies via `repo: local` (not a third root copy, and not a pinned self-reference — a pinned self-reference would lint working-tree edits against the last tagged release rather than the change being made). Every rule is `level: error` and every alert is a FAIL — no ignorable tier, same as shellcheck, the test suite, and conventional-pre-commit. Graded severities do not work here: Vale's exit code keys on `error` alerts alone, so `warning`/`suggestion` rules exit 0 and pre-commit swallows the output of a passing hook, leaving them invisible and blocking nothing. `MinAlertLevel` and `--minAlertLevel` are correspondingly absent from `.vale.ini` and the hook, being no-ops under this model. Vale covers the pattern-matchable sub-checks named in issue #84 (imperative opener, vague filler, `Use proactively`, generic reference-pointer padding) plus, per ADR-0013, one body-wide prose-pattern check ("There is/are" sentence openers) — everything else about body discipline (defaults-vs-menus, why-rationale, non-pattern-matchable judgment calls), near-miss exclusion strength, and control calibration stays LLM judgment.
 
-Both skills' Step 1, and the `vale-audit-prefilter-skill`/`-agent` pre-commit hooks, call each copy's own `scripts/vale-wrap.sh` rather than `vale` directly — a workaround for a confirmed Vale 3.15.2 limitation (see `vale-config`'s Gotchas): `text.frontmatter.description` silently stops matching once the description is a YAML block scalar (`>`/`|`) spanning 2+ physical lines, which is how most skills/agents in this repo write it. The wrapper flattens the description to one physical line in a scratch copy (padding with blank lines so every other line number is unchanged) before handing off to real `vale`; single-line descriptions pass through untouched; a relative `--config` path resolves against the caller's cwd, matching bare `vale`, not against the repo root. `tests/test-vale-wrap.sh` regression-tests this against skill-audit's copy specifically (its fixtures are all `SKILL.md`-shaped, and only skill-audit's `.vale.ini` has that glob section). Each `.vale.ini`'s section globs are path-agnostic (`[**/SKILL.md]` for skill-audit's copy; `[**/agents/*.md]`/`[**/*.agent.md]` for agent-audit's) and do no scoping on their own: Vale's `*` crosses `/`. Scoping comes from each pre-commit hook's own `files:` regex — `^plugins/[^/]+/skills/[^/]+/SKILL\.md$` for `-skill`, `^plugins/[^/]+/agents/[^/]+\.md$` for `-agent` (split into two hooks precisely because one combined hook pointed at only one copy would silently 0-file-skip the other file type) — and from the audit skills passing one explicit file per invocation. A skill outside `plugins/` (e.g. project-scope `.claude/skills/foo/SKILL.md`) matches no glob section, so Vale reports 0 files and exits 0 — which the audits read as clean. Both audits treat a 0-file Vale run as NOT RUN and fall back to full LLM judgment.
+Both skills' Step 1, and the `vale-audit-prefilter-skill`/`-agent` pre-commit hooks, call each copy's own `scripts/vale-wrap.sh` rather than `vale` directly — a workaround for a confirmed Vale 3.15.2 limitation (see `vale-config`'s Gotchas): `text.frontmatter.description` silently stops matching once the description is a YAML block scalar (`>`/`|`) spanning 2+ physical lines, which is how most skills/agents in this repo write it. The wrapper flattens the description to one physical line in a scratch copy (padding with blank lines so every other line number is unchanged) before handing off to real `vale`; single-line descriptions pass through untouched. Handed no `--config` at all, the wrapper falls back to its own sibling `assets/vale/.vale.ini`, located from `${BASH_SOURCE[0]}` rather than from the cwd — which is why both manifests' `entry:` is now the bare script path with no argument after it. pre-commit prefixes only `entry[0]` with the hook-repo clone path (`cmd = (prefix.path(cmd[0]), *cmd[1:])`), so every later argument resolves against the *consuming* repo's root: a `--config` in `.pre-commit-hooks.yaml` pointed at a path no consumer has and hard-failed every external run with `E100 [--config] Runtime error`. `.pre-commit-config.yaml` drops the argument too, deliberately keeping the two entries identical — the local `repo: local` hook resolved its `--config` correctly only because the consuming repo *was* this repo, and that divergence is why three review rounds exercised a path no external consumer takes and missed the defect. An explicit `--config` still wins, in all three argv forms (`--config X`, `--config=/abs`, `--config=rel`), and a relative one still resolves against the caller's cwd, matching bare `vale`, not the repo root; both audit skills' Step 1 still passes `--config assets/vale/.vale.ini` and is unaffected. `tests/test-vale-wrap.sh` regression-tests this against skill-audit's copy specifically (its fixtures are all `SKILL.md`-shaped, and only skill-audit's `.vale.ini` has that glob section). Each `.vale.ini`'s section globs are path-agnostic (`[**/SKILL.md]` for skill-audit's copy; `[**/agents/*.md]`/`[**/*.agent.md]` for agent-audit's) and do no scoping on their own: Vale's `*` crosses `/`. Scoping comes from each pre-commit hook's own `files:` regex and from the audit skills passing one explicit file per invocation. The two manifests scope differently on purpose: this repo's `.pre-commit-config.yaml` pins its own layout — `^plugins/[^/]+/skills/[^/]+/SKILL\.md$` for `-skill`, `^plugins/[^/]+/agents/[^/]+\.md$` for `-agent` — while the shipped `.pre-commit-hooks.yaml` stays layout-agnostic for external consumers whose skills live anywhere, using `(^|/)SKILL\.md$` and `(^|/)agents/[^/]+\.md$|\.agent\.md$`. Both manifests split the prefilter into two hooks precisely because one combined hook pointed at only one copy would silently 0-file-skip the other file type. A `SKILL.md` outside `plugins/` (e.g. project-scope `.claude/skills/foo/SKILL.md`) still matches `[**/SKILL.md]` and gets linted normally — the globs constrain filename shape, not location. Vale reports 0 files only when the path it is handed matches no glob section at all: a differently-named file, or a directory argument holding nothing that matches. That run prints `✔ 0 errors ... in 0 files.` and exits 0, indistinguishable from a clean pass, so both audits treat a 0-file Vale run as NOT RUN and fall back to full LLM judgment.
 
 This scope expands per ADR-0013: one cherry-picked low-noise `write-good`/`alex` rule landed in `styles/Kyberforge`, `Kyberforge.SentenceOpenerThereIs` (22 held-out hits, both in-corpus hits clean rewrites, zero suppressions). A second, `Kyberforge.VagueQualifier`, was cherry-picked and then deleted: 2 hits across the 41 skill/agent files, one marginal and one an unfixable false positive (`caveman/SKILL.md` quotes `of course` as an example of filler — a mention, not a use) that forced the repo's only Vale suppression comments. Also new is a sibling pre-commit hook, `skill-size-check` (`scripts/skill-size-check.sh`), enforcing agentskills.io's 500-line/5,000-token `SKILL.md` ceiling — failing only above 500 lines, matching `skill-audit/scripts/validate.sh`'s `<= 500` pass — scoped to `^plugins/[^/]+/skills/[^/]+/SKILL\.md$` only, same as `vale-audit-prefilter-skill`, so it never lints `docs/research/examples/` reference skills. It's also exposed in the root-level `.pre-commit-hooks.yaml` as `kyberforge-skill-size-check` — it has no external asset dependency, so it needed no relocation, only exposure to external consumers. File scope (`SKILL.md` + agent files) and enforcement model (rules land directly in `styles/Kyberforge`, blocking immediately, no trial tier) stay unchanged; governance.md/CONTROLS.md were evaluated and excluded as rule sources (nothing prose-pattern-matchable to mine). House convention: banned phrasing that must be mentioned rather than used goes in backticks or a fenced code block — Vale skips code spans and fences, so no suppression is needed; inline `<!-- vale Rule = NO -->` (HTML-comment form; the MDX `{/* */}` form does not work in plain Markdown) is the fallback only where backticking is impossible.
