128 underbid by ~144 bytes on a 3-input plutus_mint with inline V2 policy CBOR (preprod_test2 governor bootstrap 2026-05-08, hit FeeTooSmallUTxO 6353 lovelace short). The original constant covered the vkey witness alone but missed redeemer ex_units final-pass inflation + CBOR length-prefix shifts between unsigned (def-length) and signed (often indef-length) witness-set arrays. 256 is plenty for any single-vkey case and still cheap fee-wise (56-lovelace difference at the Cardano per-byte rate). For multi-sig flows we'd revisit, but plutus_mint's only signer is the wallet's own payment key. |
