1//! Raw TOML configuration schema for the Affinidi Messaging Mediator.
2//!
3//! This crate holds **only the serde deserialization types** that mirror the
4//! mediator's `mediator.toml` — the `*ConfigRaw` structs and their plain-serde
5//! sub-structs. Every field is the on-disk shape (mostly `String`, parsed into
6//! typed/runtime values later).
7//!
8//! It is intentionally dependency-light (serde + the lean tier of
9//! `affinidi-messaging-mediator-common`, for `DatabaseConfigRaw`). The
10//! **resolved** runtime `Config` — opened secret backends, JWT keys, the
11//! DID-resolver client, the VTA refresher — and all `ConfigRaw → Config`
12//! conversions stay in the mediator binary, which re-exports these types so
13//! existing `crate::common::config::*` paths keep resolving.
14//!
15//! The goal (mediator simplification T18) is one schema, two consumers: the
16//! mediator and (later) the `mediator-setup` wizard, which today renders this
17//! TOML by hand with no shared types. Env-var override logic and boot-time
18//! validation move here in a follow-up (T18b), once they carry a crate-local
19//! error type instead of the mediator's server-tier `MediatorError`.
