// justifies: INV-TEST-PANIC-AS-ASSERTION; trybuild harness in tests/derive_multi_event_reactor_errors.rs uses panic! internally to surface fixture mismatches; test bodies follow panic-as-assertion idiom.

//! Compile-fail coverage for the `#[derive(MultiEventReactor)]` attribute contract.
//! Harness pattern: Fault-Injection Harness (compile-fail lane).
//!
//! Each fixture in `tests/ui/mer_*.rs` violates a specific contract rule and
//! must fail to compile with a span-pointed error. The `.stderr` files pin
//! the exact error wording so regressions in message clarity or span quality
//! surface as trybuild diffs.
