Two coupled fixes for the same root cause: the coin selector was too
conservative for "send most of what I have" cases.
1. min_change_required now drops to 0 for ada-only sends (kept at
min_utxo_lovelace for asset-bearing sends where change has to
carry leftover policy IDs). Downstream pass2 already folds
sub-min change into fee on the ada-only happy path; the selector
was reserving slack the chain doesn't actually need.
2. fee_pass1 dropped from 500_000 to 200_000. Real fees:
1-in 1-out ada-only send : ~166 k
1-in 2-out (with change) : ~178 k
CIP-25 mint w/ metadata : ~210 k
500_000 was overgenerous safety budget. 200_000 is enough headroom
for the basic-send case (which is the one that needed to drain to
fee) without crowding mint paths (which typically have plenty of
lovelace headroom anyway).
Surfaced 2026-05-05 zeroing out the mainnet test wallet:
2 ADA balance, 1.8 ADA send refused upstream as
"need 3300000 (target+fee+min_change), have 2000000"
even though the chain math was fine. New regression
ada_only_send_can_drain_to_fee covers the case.
