+//! Phase 17 (Track L.15) — Go framework adapter integration tests.
+//!
+//! Each test exercises `detect_binding` end-to-end against a fixture
+//! file under `tests/dynamic_fixtures/go_frameworks/`, asserting that
+//! the right adapter fires, the binding carries
+//! `EntryKind::HttpRoute`, and the `RouteShape` matches the brief.
+//! 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.
