## Findings (1)

```yaml
- file: solutions/observability/streams/streams.md
line: 111
category: invalid-applies-to-syntax
severity: medium
evidence: >
Section-level applies_to block uses ``` yaml {applies_to}``` (note the
space between the opening fence and 'yaml'), which does not match the
documented format. Every other section-level annotation in this file and
across the repo uses either ```{applies_to}``` or ```yaml {applies_to}```
(no leading space). The extraneous space may prevent the docs-builder from
recognising the block as an applies_to directive, rendering it as a plain
YAML code block and silently dropping the badge for the 'Streams API'
section.
suggested_fix: |
### Streams API [streams-api]
```{applies_to}
stack: preview 9.1
serverless: preview
```
```

## Done when
- The `streams.md` Streams API section uses a recognised `applies_to` code-fence syntax.
- A PR addressing this issue is merged.

## Notes
- All other files in scope have valid `applies_to` frontmatter and correct syntax; no further changes needed.
