Making my first post at Delving (only because I’m specifically referenced, I just lurk otherwise) to say the post does not mention OP_CTV specifically, but the need to make a commitment to a future transaction like the primitive of what OP_CTV enables would be a necessary part of the vaulting structure from my view.
Most of my reading of OP_VAULT is from the official BIP 345 which makes several references to OP_CTV.
I’m in support of CTV + CSFS.
