	# Estate Rules — enforces hyperpolymath estate-wide conventions that apply to
	# this repository:
	# * root shape (allowlist of permitted root entries)
	# * AsciiDoc-by-default (no .md files under docs/)
	#
	# NOTE: the estate "no-ziguage" (V / vlang.io ban) check is intentionally
	# OMITTED here. This repository legitimately uses Zig for its C-ABI FFI seam
	# (ffi-zig/), and the upstream check-no-vlang.sh greps the literal string
	# "zig", which would false-positive on every legitimate Zig file. The estate
	# ban targets V (vlang.io), not Zig — so the check does not apply to this repo.
	#
	# Each rule is enforced by an executable check script under scripts/.
