15//! Redb-backed Write-Ahead Log implementation for Drasi transient sources.
16//!
17//! This crate implements the [`WalProvider`](drasi_lib::WalProvider) trait
18//! using [redb](https://docs.rs/redb) for durable event storage. Each
19//! registered source gets its own redb file at `{root_dir}/{source_id}.redb`.
20//!
21//! Events are serialized via explicit DTOs (not by deriving serde on core
22//! domain types), keeping the wire format decoupled from the core model.
