How auto-repair works (Pro)
repair_vault only makes additive changes:
- Broken
[[links]]→ replaced with plain text (the link text is preserved) - Missing frontmatter → adds a default YAML block with title and type
It never deletes files, removes content, or modifies existing frontmatter values.
Pro tier
The free tier detects every category of vault rot. The Pro tier unlocks repair_vault — one call to fix the safe categories automatically.
