+FR-CULL-8a's eye state, under FR-CULL-13's rule. Three more models run over every face the
+pipeline already aligns, and what they produce is a **filter term** — "eyes open", on the people
+filter — and a badge on the People screen. Nothing acts on it: FR-CULL-13 says the signal is
+evidence, shown and filterable, and never holds the pen, and §3.9.1's exclusion of blink
+*detection* was re-read the same day as the exclusion of blink *selection* it always was. The chip
+narrows the grid the way a star count does, and rates nothing. Head pose, the other half of
+FR-CULL-8a, is not built; §17.3 says what stands in for it.
