1//! `truefix-core` — FIX message model, field types, and the SOH wire codec.
2//!
3//! Provides [`Field`], [`FieldMap`], [`Group`], and [`Message`] (header/body/trailer),
4//! plus [`encode`]/[`decode`] that compute and verify BodyLength (tag 9) and CheckSum
5//! (tag 10). All parsing returns typed errors and never panics (Constitution Principle I).
6//!
7//! Repeating-group *structure* is modelled here; dictionary-driven group *parsing* from a
8//! flat wire message arrives with `truefix-dict` (Stage S4). At this layer, decoding yields
9//! flat ordered fields, which still round-trips byte-for-byte.
10//!
11//! Design: `specs/001-fix-engine-parity/`.
