Research direction

Start at the sendtoaddress RPC path and reproduce the Elements 23.2.2 case using a whole liquid balance minus a 75–200 sat fee margin, with CT discount enabled and without subtractfeefromamount. Trace the fee and confidential-transaction discount handling; done means the call succeeds for that balance and no longer returns Insufficient funds.

Written by the indexing model from the issue text.

Description

needs reproduction

When sendtoaddress is called to send the whole liquid balance less margin for fee (75-200 sats) CT discount is not applied and results in:

error code: -6
error message:
Insufficient funds

We understand there is an option subtractfeefromamount, but prefer not to use it.
