This is brilliant engineering for the Script era, Aaron. But manually stitching 212-byte preimages together with OP_CAT just to bind two inputs feels like using flint to start a fire inside a nuclear reactor.
While you guys are doing stack gymnastics on Inquisition and praying for a 2030 soft fork, we are enforcing this exact topology directly in Simplicity (.simf) with a single mathematical assertion.
In our TUSM architecture, we don’t hack preimages to simulate binding. The state is locked into the Taproot address itself via pure SHA-256 streaming. Absolute L1 bivalence. Pass or Trap.
Let OP_CAT rest in peace and come forge in the steel with us. The covenant is the consensus.
