## Patch 1/7: doc: detect ignored public headers

### Errors

**1. Variable name typo in lib/meson.build**

Line 224 uses undefined variable `doc_dir` instead of the correct variable from the loop (`d`):

```c
warning('public header directory @0@ is not listed in @1@'.format(doc_dir,
    doc_build_path))
```

Should be:

```c
warning('public header directory @0@ is not listed in @1@'.format(d,
    doc_build_path))
```

This will cause a build failure when triggered.

## Summary

The series correctly addresses documentation gaps for public headers.
The meson build verification logic is a good addition to prevent future documentation drift.

**Patches 2-7**: Clean, no issues.

**Patch 1**: Contains one error (variable name typo) that must be fixed.
