	# Phase C lane L-C7 of gHashTag/trios#536. Idempotent gate that only closes
	# gHashTag/trios#446 when every cell of the 312-cell Format×Algorithm matrix
	# in `ssot.bpb_samples` is non-empty with bpb>1.0. Runs hourly on a 17-min
	# offset from matrix-bot so the live body is fresh, plus on demand via
	# workflow_dispatch.
	#
	# Anchor: phi^2 + phi^-2 = 3.
