+//! Java fixture integration tests (Phase 05 acceptance gate).
+//!
+//! Runs the dynamic verification pipeline against each Java fixture and asserts
+//! the expected verdict. Requires `--features dynamic` and `java`/`javac` on PATH.
+//!
+//! Entry points follow: `public static void FuncName(String)` in class `Entry`.
+//! The harness wraps each fixture in a generated `NyxHarness.java` that reads
+//! `NYX_PAYLOAD` and calls `Entry.FuncName(payload)`.
+//!
+//! Run with: `cargo nextest run --features dynamic --test java_fixtures`
