//! Configuration files for a conversation repo.
//!
//! Each submodule owns one file per ARCH §2.2 — see [`version`],
//! [`models`] (global, at the harness root — the optional `adapter:`
//! override), [`per_repo_providers`] (per-repo `roles:` section),
//! [`manifest`], [`workflow`]. [`cross`] enforces references across
//! files: a workflow's `dispatch(<role>)` action must name a role
//! declared in the per-repo `roles:` section.
