-//! Java fixture integration tests (Phase 05 acceptance gate).
+//! Java fixture integration tests (Phase 05 acceptance gate + Phase 14
+//! per-shape acceptance).
 //!
-//! Runs the dynamic verification pipeline against each Java fixture and asserts
-//! the expected verdict. Requires `--features dynamic` and `java`/`javac` on PATH.
+//! Phase 05 surface: runs `verify_finding` against each legacy
+//! `tests/dynamic_fixtures/java/<name>.java` (entry class `Entry`,
+//! `public static void <fn>(String)`) and asserts the expected verdict.
 //!
-//! 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)`.
+//! Phase 14 surface (`#[cfg(feature = "dynamic")] mod phase14_shape_tests`):
+//! for each [`nyx_scanner::dynamic::lang::java::JavaShape`] asserts
+//! `Confirmed` on the vuln fixture and `NotConfirmed` on the benign
+//! fixture under the `tests/dynamic_fixtures/java/<shape>/` directory.
+//!
+//! Prerequisites: `requires: docker-or-jdk17` — the suite skips cleanly
+//! when `javac` / `java` is unavailable on the host (Phase 29 will wire
+//! the structured prereq system; for now the suite checks
+//! `java --version` exit status and returns early on failure).
 //!
 //! Run with: `cargo nextest run --features dynamic --test java_fixtures`
