# KYE Protocol™ rule packs — behavioural logic

Bundles of decision rules. Each rule maps to a control row. Each verdict cites the rule that fired.

## 70 rule packs (and counting)

What it is. Why it matters. What to do next.

Each rule pack carries: a manifest (what it applies to + which rules it includes) + N rule files (condition + effect + reason\_code + control\_refs). Adding a new compliance regime is a JSON PR, not a code change.
