#![cfg(feature = "server")]

//! Integration tests for Axum extraction and the `current_auth` context reader.
//!
//! The context reader reads from `FullstackContext`, not directly from the live
//! axum `Request<Body>::extensions()`. The bridge is one-way: at the start
//! of a server-function request, dioxus-server splits the request into
//! `Parts`, constructs a `FullstackContext::new(parts)`, then runs the
//! handler future inside `ctx.scope(...)` so the task-local
//! `FULLSTACK_CONTEXT` is set. `ctx.extension::<T>()` then reads from
//! `parts.extensions`, which is exactly where `ClerkAuthLayer` deposits
//! the auth.
//!
//! The plan's original test design wires a plain axum handler directly,
//! which would never see a `FullstackContext` (no scope set), so
//! `current_auth()` would return `Err(InvalidConfig(...))`. We
//! reproduce dioxus-server's bridge here with a tiny tower middleware
//! that wraps the inner handler call in `FullstackContext::new(parts)
//! .scope(...)`. This faithfully exercises the production code path
//! without pulling in the full dioxus-server runtime.
