-# Project Plan: Unilang Codestyle and Documentation Review
+# Project Plan: Unilang Test File Documentation
 
 ### Goal
-*   Iterate through each file of the `unilang` crate, ensuring all code adheres to the established codestyle rules and has concise, accurate documentation.
+*   Add comprehensive documentation to all test files, including references to the Test Matrix, to ensure clarity and maintainability.
 
 ### Progress
-*   ✅ Codestyle Review Complete
+*   ✅ Test Documentation Complete
 
 ### Target Crate
 *   module/move/unilang
 
 ### Relevant Context
 *   Files to Include (for AI's reference, if `read_file` is planned, primarily from Target Crate):
-    *   All `.rs` files within `module/move/unilang/src` and `module/move/unilang/tests`.
+    *   `module/move/unilang/tests/inc/phase1/full_pipeline_test.rs`
 
 ### Expected Behavior Rules / Specifications (for Target Crate)
-*   All files must pass `cargo clippy` with the workspace lint settings without warnings.
-*   All public items should have clear, concise documentation.
-*   Code formatting should be consistent across the entire crate.
+*   Test functions should have doc comments explaining their purpose.
+*   Each test function should reference the Test Matrix row(s) it covers.

 ### Task Requirements
-*   Systematically review every `.rs` file.
-*   Apply codestyle fixes and add documentation as needed.
+*   Add documentation to test files.
 
 ### Project Requirements
 *   Maintain consistency with the overall workspace codestyle.
 
 ### Notes & Insights
-*   This is a good opportunity to improve the overall quality and maintainability of the crate.
-*   The `former` crate usage is still disabled and should be noted for future work.
\ No newline at end of file
+*   This will significantly improve the test suite's readability.
