yomihon reports invalid fields, unresolved links and other detected problems without repairing files.

## Where they appear

Each note shows its diagnostics beside the text. The health page gathers vault findings, including broken links, uncited notes, ambiguous names and invalid statuses.

[[A note with a fault in its frontmatter]] demonstrates an invalid status. [[Wikilinks in this dialect]] demonstrates a missing target and a missing section.

## What a diagnostic says

A diagnostic identifies the fault and its effect. For a missing section, the note still links, but the requested fragment has no matching heading. Check the heading or correct the link.
