utc.rs

//! Decoded view over [`Utc`].
//!
//! Mirrors the two-stage shape established by [`UtiProjection`] /
//! [`UtiSnapshot`] in [`super::uti`]. The projection wraps the source
//! [`Utc`] reference for file-native access; the snapshot adds the
//! resolved data the view's query methods read from. Coverage:
//! scalar-id resolutions (race, appearance, portrait, soundset,
//! alignment), typed [`DecodedClass`] variants over `ClassList`,
//! typed [`DecodedSpecialAbility`] variants over `SpecAbilityList`,
//! and typed [`DecodedFeat`] variants over `FeatList`.

/// One decoded entry from a UTC's `FeatList`, dispatched by matching
/// the `feat.2da` row's `label` cell against the set of vanilla feat
/// labels the corpus references.
///
/// Vanilla `FeatList` entries carry a single `Feat: u16` field, so
/// every typed variant has the same shape: a raw `feat_id` preserved
/// from the source GFF. Dispatch is by `label`, not by raw `feat_id`,
/// so a mod that re-numbers a vanilla feat still routes to its typed
/// variant.
///
/// Mod-added rows, vanilla feat rows the corpus never assigns, and
/// missing or out-of-range entries all surface as
/// [`DecodedFeat::Unknown`] carrying the raw id and the resolved
/// label (when reachable).
// CLIPPY: feat family prefixes (`ArmourProf`, `WeaponProf`,
// `WeaponFocus`, `WeaponSpec`, with `ForceJump`, `SneakAttack`,
// `DroidUpgrade`, etc. arriving in later commits) are load-bearing
// for grouping; the shared prefix is the feat family, not noise.
