Fields

identity_token_info_default_structure_version: u16

identity_token_status_default_structure_version: u16

token_contract_info_default_structure_version: u16

token_config_update_action_id_version: u16

Version for the token config update action_id calculation. v0: uses only the u8 discriminant of the config change item (vulnerable to value swap) v1: includes the full serialized config change item in the hash

token_set_price_action_id_version: u16

Version for the set-price-for-direct-purchase action_id calculation. v0: uses only minimum_purchase_amount_and_price().1 (vulnerable to schedule swap) v1: includes the full serialized TokenPricingSchedule in the hash

distribution_function_evaluate_version: u16

Version for the transcendental math (ln, exp, pow) in DistributionFunction::evaluate. v0: std f64 methods, which link to the platform libm and differ by 1 ulp between aarch64-musl and x86_64-musl (musl’s __FP_FAST_FMA branch); a claim amount can land on either side of a floor boundary and split the app hash. v1: the pinned pure-Rust libm crate, bit-identical on every target Platform builds for.

reward_distribution_max_cycle_moment_version: u16

Version for RewardDistributionType::max_cycle_moment, the cap on how far a single perpetual distribution claim may redeem. v0: start + interval * cycles in the moment’s own width. For epoch-based distributions that width is u16, so interval * 32_767 (the fixed-amount cycle cap) plus a nonzero start wraps; release builds carry no overflow checks, the wrapped cap lands below the start and the claim is refused as having no rewards, forever. v1: computed in u64 with saturating arithmetic and capped before narrowing back; the epoch cap is the last completed cycle moment (the previous epoch for an interval of one, as in v0) so the evaluated range always ends on a cycle boundary.

distribution_function_cycle_epochs_version: u16

Version for the epochs a perpetual distribution cycle spans, which weight an evonode reward by participation in DistributionFunction::evaluate_interval. v0: the cycle’s step index read as an epoch, right only for an interval of one; for a wider interval it names epochs before the distribution started, which are outside the claim’s epoch window, and the claim fails for want of their epoch info. v1: the interval’s epochs ending at the cycle moment, the span the fixed-amount fast path already weights.
