Full sweep of docs/ · 1 total in scope · corpus 1 pages.

## Findings (1)

```yaml
- file: docs/test-page.md
line: 5
category: invalid-applies-to-value
severity: high
evidence: "applies_to.stack.ga uses undocumented version value 'all'; reference specifies x.x+, x.x-y.y, or =x.x formats"
suggested_fix: |
applies_to:
stack:
ga: 8.0+
```

## Done when
- All listed pages have a valid `applies_to` block per the verified reference.
- A PR addressing this issue is merged.

## Notes
- The value `all` is not documented in the [applies_to reference](/docs/contribute-docs/how-to/cumulative-docs/reference). Use a specific version format like `8.0+` for "all versions from 8.0 onwards" or remove the version if truly all versions apply.
