# Rule: WIIFY implied throughout — each labeled section (A-J) contains ≥3
# reader-second-person markers: "for you[r X]", "what this means", "your
# engineer/CFO/CISO/CTO/actuary/IC/Ops/underwriter/auditor/counsel", "take
# to your meeting".
#
# Heuristic catches sections that forgot the reader; not a replacement for
# ghost-read's semantic check, but it surfaces structural WIIFY gaps as a
# fast file-grep-able signal.
#
# Implementation uses node (instead of awk) because macOS ships BSD awk
# which lacks 3-arg match()/regex support gnu awk has.

# Only enforce on full-structured blog posts (labeled A-J letter pattern)
