Passive metadata is documentation: someone has to go look. Active metadata emits events when it changes, and other systems subscribe and act: block a deploy that breaks a critical element, alert a steward, update an AI agent's context, reassign ownership.

**Test:** if nothing breaks when the metadata is wrong, it isn't active yet.
