//! Phase 14 (Track L.12) — Java framework adapter integration tests.
//!
//! Each test drives `detect_binding` end-to-end against a fixture
//! file under `tests/dynamic_fixtures/java/`, asserting that the
//! right adapter fires, the binding carries `EntryKind::HttpRoute`,
//! and the `RouteShape` matches the brief's contract.  Benign
//! fixtures must produce the same adapter binding shape as the vuln
//! fixtures — the adapter only models the route, the differential
//! outcome of a verifier run is what distinguishes the two.
//!
//! The Spring fixture lives under `spring_controller/`, the Quarkus
//! fixture under `quarkus_route/`, the Servlet doGet/doPost
//! fixtures under `servlet_doget/` and `servlet_dopost/`, and the
//! Micronaut fixture under `micronaut_route/` (introduced in this
//! phase).
