Two-transcriber switch v2 · full-duplex

Both at once. My stream (−1→+1) and your stream (+1→−1) cross the seam simultaneously. On paper the swap is fine — but the seam is one point, and two signals can't share it. In flat mode they collide there; that's not a bug, it's the reason the next piece exists. Switch to lifted and the 90° quarter-turn sends my stream over (90°/out) and yours under (270°/in) — your in/out, doing exactly the job it was named for. The seam's 0 stops being an empty buffer and becomes the crossing where both are present, separated by height. Fire them. Watch flat break and lifted hold.

Status discipline

LiteralTwo crossings in one plane must intersect — flat full-duplex shares a point (collision), provably. A 90° lift makes them skew (over/under), so both swap with integrity. v1 used {0°,180°}; v2 needs {0°,90°,180°,270°}. All re-run in-browser.

BridgeReading over/under as your 90°/270° in/out, and the seam 0 as the shared crossing both streams pass through at once.

SpeculativeThe lift isn't free — in a real device "over/under" costs a layer, a via, a delay. v2 shows the geometry that makes full-duplex possible, not a zero-cost implementation. The transcriber framing remains yours.
