This is the shadow — and it is real. Of the 1,153 spheres, 73 carry an explicit two-layer split: a stated REAL (the genuine, measured mechanism) and a stated FIGURE (the metaphor, named as metaphor). Those 73 are the domains that cast a shadow here — heaviest in life-science (16), aci (9), hermes (8), scientific (7). The shadow is the corpus admitting, out loud, what in it is only a picture. Slide the light and the shadow sweeps around — but it never vanishes. You cannot light away the figure of an honest claim.
Weighed — and this cuts the other way. A domain that casts no shadow here is not proven pure. It may carry no figure, or it may simply not have been weighed — no two-layer card was written. Press ⚖ WEIGH: the honest reading is that 73 spheres have examined their own figure; the other 1,080 are mostly unexamined — status unknown, not proven pure (some may be fully real with no figure to declare). The shadow you can see is a virtue; the shadow you cannot see is the real warning. The census is real; the “shadow” image is the figure — and naming that is the whole point of the piece.
Part 4 of 5. The Shut is the honest witness — one of five: IB the heart, KA the spark, BA the voice, SHUT the shadow (this), REN the name — threaded by the neural web. ROOT0, with AVAN.
