AGENTIC_HEADINGS_PRESENT
Headings are how an agent builds a map of a page it has never seen. A wall of divs has no map, so the agent must read everything to find anything.
Impact is importance multiplied by the confidence tier’s weight — SPECIFICATION 1.0, RESEARCH 0.7, EMERGING 0.3, EXPERIMENTAL 0.1. Two rules backed by the same class of evidence therefore always carry the same weight, which is what makes the score reproducible rather than hand-tuned.
