guideline grounding Shipped
What this lens looks for
Keep the guideline bounded to a single topic — flag any rule that has crept into a second topic. Tie the guidance to the principles it implements and the recipes/guidelines it neighbors, citing in related only genuine links. Check references/guidelines/ for the topic boundary with existing guidelines.
What its verifier checks
The guideline covers one topic, not two; cited principles are ones it actually implements; related guidelines/recipes are genuine neighbors; the topic boundary with existing guidelines is respected, not overlapped.
