1//! DEPRECATED: Stream-based guidance replaces middleware
2//!
3//! This module is kept for historical reference only. Error guidance is now
4//! provided via `PlexusStreamEvent::Guidance` events in error streams.
5//!
6//! **Migration:** Frontends should handle guidance events instead of parsing
7//! JSON-RPC error data. See the frontend migration guide at:
8//! `docs/architecture/16680880693241553663_frontend-guidance-migration.md`
9//!
10//! **Architecture:** See stream-based guidance design at:
11//! `docs/architecture/16680881573410764543_guidance-stream-based-errors.md`
