Covenants with CAT and ECDSA

In his article, CAT and Schnorr Tricks I, Andrew Poelstra showed how to emulate OP_CHECKSIGFROMSTACK-like covenants using only OP_CATand Schnorr signatures.

	// 1. The return type isn’t Self.

The High-Level Idea

Recall the ECDSA Signature Equation

	[keys.normal]
	C-g = [":new", ":insert-output lazygit", ":buffer-close!", ":redraw"]

	{
	"name": "Alpine",
	"image": "mcr.microsoft.com/devcontainers/base:alpine",
