   Current behavior:

   0src/bitcoin-cli -signet decodescript 2103d3b9c8cc852f3b4a06bad1711fd1a1761a592bf1475edc0a5f97b31759eba330ac736476a914b6e87320e876a740fc1365aeb1f4b6ab2fe4210b88ad53b268

   It would be nice if this (also) returned miniscript.

   Perhaps getaddressinfo could do this as well (after #24148).

   After #24148 i think it should be the default behaviour to show a Miniscript descriptor (for the "desc" field) if one could be parsed: InferDescriptor would try parsing a Miniscript under P2WSH context (as in your example). EDIT: InferDescriptor is using a dummy sig provider so it wouldn’t work, see #27007 (comment).

   However, note your Script here would not be parsed because the Miniscript parser is not passed the preimage to the key hash for OP_DUP OP_HASH160 b6e87320e876a740fc1365aeb1f4b6ab2fe4210b OP_EQUALVERIFY OP_CHECKSIGVERIFY. So i’d say it’s the best we can reasonably do.

   hmm seems I opened up a mostly similar issue in https://github.com/bitcoin/bitcoin/issues/27007
