Errors that a Solana program can return.

#[repr(u64)] with EXPLICIT discriminants is load-bearing for binary size: variant k (for the fieldless builtins, k = 1..=24) encodes to the runtime code (k + 1) << 32, so [From<ProgramError> for u64] is one tag read + one shift instead of a 25-arm match. The DWARF size attribution measured that match at 880 bytes, 13% of the parity vault’s .text, because the error lowering inlines into every entrypoint. Keep new variants in this scheme: append with the next sequential discriminant and the conversion stays arm-free (the exhaustive u64_conversion_matches_reference_for_every_variant test enforces the correspondence).
