MDS067: callout-type

Validate Obsidian callout types against an allowed set.

A blockquote whose first paragraph begins with [!type] is an Obsidian callout. MDS067 flags the callout when type is not in the effective allow set. Matching is case-insensitive. Custom types are opt-in via the allow setting; the rule turns off entirely under allow-unknown: true.

Disabled by default. Set convention: obsidian (or toggle the rule on directly) to enable it.

# Settings

The built-in vocabulary is the Obsidian base set:

• note
• abstract (aliases summary, tldr)
• info (alias todo)
• tip (aliases hint, important)
• success (aliases check, done)
• question (aliases help, faq)
• warning (aliases caution, attention)
• failure (aliases fail, missing)
• danger (alias error)
• bug
• example
• quote (alias cite)

allow uses append merge semantics. A kind or override that adds a custom type preserves entries from earlier layers.
