<Replace this paragraph with the rule. Say what to do, what not to do, and the one exception if there is one. Keep it prescriptive and short enough to quote whole; a planning or review agent reads it only when a condition above matches the work in front of it.>

Layout reminder, delete once the rule is written: only top-level `.md` files with `title` and `applies_when` are discovered as rules; `README.md` is this pack's description, never a rule; subfolders are storage for the evidence and data a rule points at.
