Defame1297 45cd26045a refactor(lint): retrofit vale-config to the ADR-0020 context contract
Description 657 -> 244 chars, body 504 -> 342 words, Gotchas 50% -> 24%.
The 50% was the worst ratio in the corpus and a real inverted body, not
the denominator artefact the ratio usually flags: half the body was a
Gotchas section doing duty as reference material.

A clean-context audit caught the split leaving a false statement behind.
Gotcha 1's kernel lost the qualifier that only package styles need
fetching, so it asserted that any style vale sync has not fetched fails
-- contradicting the same file twice, since the built-in Vale style and
any committed custom style are never fetched. An agent adding a custom
style would have added a spurious Packages entry and broken vale sync
outright. The qualifier is restored in the body rather than behind a
fourth reference pointer.

Also corrects the moved fixture's framing, which tabulated a control row
under a heading claiming it came from a multi-line fixture.

name: vale-config
description: >
Use when installing or configuring Vale, the prose/style linter — writing a `.vale.ini` whose
styles are fetched and actually activated — even when the user says only "set up prose
linting". Not running Vale on an existing config -> `vale-run`.

## Gotchas
- A style in `BasedOnStyles` that is neither built-in nor already under `StylesPath` finds nothing until `vale sync` fetches it — a clean run is not proof anything linted.
- `.vale.ini` is order-sensitive: core settings first, then `[formats]`, then glob sections. Anything written below a glob header applies only to files matching that glob.
- A rule scoped to `text.frontmatter.<key>` silently matches nothing when the field spans multiple lines in most YAML forms. If you scope a rule to frontmatter, read `references/configuration-reference.md` first.
## Setup workflow
- [ ] **Install** the `vale` binary: `brew install vale` (macOS), `snap install vale` (Linux), `choco install vale` (Windows), or `docker pull jdkato/vale`.
- [ ] **Pick a `StylesPath`** (conventionally `styles`) and create it. This is where all styles, dictionaries, and vocab live.
- [ ] **Write `.vale.ini`** at the project root with at minimum:
```ini
StylesPath = styles
MinAlertLevel = suggestion
[*.md]
BasedOnStyles = Vale
```
`Vale` here is the built-in style (`Vale.Spelling`, `Vale.Terms`, `Vale.Avoid`, `Vale.Repetition`) — no download needed, it always works.
- [ ] **Add third-party styles** (optional) by declaring them in `Packages`, then activating them in the same or another glob's `BasedOnStyles`:
```ini
Packages = Google, write-good
[*.md]
BasedOnStyles = Vale, Google, write-good
```
- [ ] **Sync**: run `vale sync` to download everything listed in `Packages` into `StylesPath`.
- [ ] **Verify activation**: confirm every style named in `Packages` also appears in at least one glob's `BasedOnStyles` — an unreferenced package downloads but never lints anything.
For the full `.vale.ini` field reference (formats mapping, vocab, local overrides, custom rule header fields), read `references/configuration-reference.md`.
## Custom styles
A custom style is just a new subdirectory under `StylesPath`, holding one YAML file per rule:
```
styles/
└── MyStyle/
└── NoJargon.yml
```
Each rule file needs `extends` (the check it implements, e.g. `existence`) and `message` at minimum. Activate the style the same way as any other: add `MyStyle` to `BasedOnStyles` for the relevant glob. If a rule needs a field beyond those two, read `references/configuration-reference.md` for the full rule header field table.
