Expand description

The fee a canonical ZIP 318 crossing pays at target_height, obtained by asking the STANDARD ZIP 317 rule what the canonical shape costs.

ZIP 318 requires this exact fee. Any other value partitions the anonymity set, so a transaction paying a non-standard fee is not a canonical crossing however well its structure matches. The standard rule is used rather than the caller’s: a proposal built on a fixed non-standard rule would otherwise be compared against its own fee and always agree.
