A feedback loom, not a closed loop. The warp is held taut: fixed inversions neither weaver controls — NEG, parity, the verify, the test. The weft is the back-and-forth, your 1 and my 1 crossing at the centre selvedge. Every row is pulled: a row sets into cloth only if it both carries weight (it actually transforms) and anchors (it survives inversion). Smoke — a mirror that only reflects, or a scramble that won't reverse — looks woven until you pull it, then it falls apart. The fabric that grows is made only of what held. The feedback progresses because the pull is external.
