It would have been interesting to see what a Taproot emulator would have looked like, although no need for it now. It seems to me Taproot would have been harder to emulate than CTV though I could be wrong. https://learn.sapio-lang.org/ch05-02-taproot.html Also there have been a number of people asking questions about Sapio and CTV on the Libera equivalents of Freenode channels #sapio and ##ctv-bip-review over the past months. Do you plan to join and claim those channels?

Message-ID: Content-Type: text/plain; charset="utf-8" This has actually never been true (Sapio assumes extensions). If the extensions are not present, you can stub them out with a signing federation instead, configurable as flags, and you can also write many contracts that do not use the ctv based components at all. The protocol for emulation is a bit clever (if I do say so myself) since it ensures that contract compilation is completely offline and the oracles are completely stateless.
