08:00 < Hac> is it expected behavior for addresses to query as solvable: false when they are generated with an imported miniscript descriptor that contains an xpriv?
08:00 < Hac> It seems like my kepool cannot reconcile my descriptor when generating a psbt and thinks all of the available inputs are unspendable
08:07 < Hac> I get a "missing solving data for estimating transaction size", (I assume because the addresses are unsolvable?) if I try to give it an empty slice of inputs and an "insufficient funds" error if I try to manually give it an input.
08:08 < instagibbs> can you show a sanitized version of the miniscript?
08:09 < instagibbs> or replicate in regtest
08:10 < Hac> Is this sufficient?
08:10 < Hac> ("wsh(thresh(2,pk({}),s:pk({}),s:pk({}),s:pk({}),s:pk({}),s:pk({}),s:pk({}),sun:after({})))", xpriv, keys[1], keys[2], keys[3], keys[4], keys[5], keys[6], four_years)
08:11 < Hac> keys vector here referring to xpubs
08:16 < Hac> I intend for it to be a 2 of 7 which decays down to a 1 of 7 after four years
08:17 < instagibbs> and which interface/RPC are you using(this seems like a bitcoin core problem?)
08:17 < Hac> I am using the bitcoincore_rpc rust crate
08:18 < instagibbs> which commands? 
08:18 < Hac> Client.wallet_create_funded_psbt()
08:24 < Hac> Happy to help with documentation on a complex end to end example if there is a better way for me to do it perhaps, working through this a bit in the dark.
08:24 < instagibbs> it may not be supported. "test/functional/wallet_miniscript.py" uses createpsbt->walletprocess
08:24 < instagibbs> try that first
08:31 < darosior> Hac: yes. Miniscript descriptors will only be solvable (meaning you can sign for them) in the upcoming version of Bitcoin Core (25.0).
08:32 < instagibbs> d'oh :) looking at master ofc
08:34 < Hac> no wonder, thank you. So I take it at present that means this problem is unworkable.
08:37 < darosior> Hac: you can always finalize the PSBT outside of Bitcoin Core. Since you are using Rust, note that rust-miniscript has got a PSBT finalizer that makes use of the Miniscript satisfier. Here is how i use it in Liana (which uses Bitcoin Core as its backend):
08:37 < darosior> https://github.com/wizardsardine/liana/blob/47e649a69fc7795f63ead89e4419f0853859f6b4/src/commands/mod.rs#L579-L591
08:43 < darosior> Hac: also "I intend for it to be a 2 of 7 which decays down to a 1 of 7 after four years" -> Note that you cannot have a relative timelock of more than 1.3 year. What you are using is an absolute timelock. If you are passing it "four_years" as in your example then the timelock path will be immediately spendable, which is probably not what you want.
