//! # ethos-core
//!
//! The Ethos product contract in Rust: canonical document model, deterministic
//! serialization (c14n v1), fingerprints, stable error/warning codes, page-range
//! configuration, and the trait boundaries between crates.
//!
//! Normative references: `schemas/*.json` and `docs/determinism-contract.md`.
//! Contract changes happen only via `contract-change` PRs with version bumps.
//!
//! ## Feature layers (invariant 4: verify portability)
//!
//! - `grounding` — the [`grounding::GroundingSource`] trait module alone. `ethos-verify`
//!   depends on `ethos-core` with `default-features = false, features = ["grounding", "verify-types"]`
//!   and therefore can never see parser internals. CI builds it that way to prove it.
//! - `verify-types` — verification report/config schema types + stable warning codes.
//! - `full` (default) — canonical model, c14n, fingerprints, geometry, config, traits.
//! - `crop-element` — source-only pre-alpha crop descriptor API, intentionally opt-in.
