Implications

Implications automatically apply related tags when you tag an item. They’re applied at write-time, not query-time, which makes searches fast.

How Implications Work

When you create an implication A → B:

Any time someone adds tag A to an item, tag B is automatically added
All existing items with tag A are immediately updated to include tag B
Implications can chain: dog → canine → mammal → animal

Example: If you have dog → canine → animal, tagging something with “dog” automatically applies all three tags.
