+## Testing and Compliance
+
+The codebase is strictly enforced to achieve **100% test coverage** and **100% documentation coverage** without relying on configuration bypasses (such as `tarpaulin.toml` exceptions or injected `#![allow(missing_docs)]` pragmas). Continuous Integration (CI) enforces these targets.

 `cdd-rust` has achieved **100% compliance** with the features introduced in the OpenAPI 3.2.0 specification. It features a highly compliant custom parser found in `core/src/oas`.
 
+## Strict Code Standards
+
+As part of maintaining high compliance standards, `cdd-rust` strictly adheres to **100% Test Coverage** and **100% Documentation Coverage** across all source files. No `exclude-files` or coverage-bypassing exceptions (e.g., `#![cfg(not(tarpaulin_include))]` or `#![allow(missing_docs)]`) are permitted.
+
 ## Supported Workflows
 
 - **Codebase ➔ OpenAPI:** Partially supported natively. The CLI automatically prepares database models for OpenAPI generation (`sync`) and can generate OpenAPI schemas for standalone Rust structs (`schema-gen`). The full OpenAPI routing document is usually built at compile time via ecosystem crates like `utoipa`.

 **cdd-rust** is a compiler-driven development toolchain designed to enable "Surgical" Compiler-Driven Development.
 
+With **100% test and documentation coverage natively enforced** across the workspace, `cdd-rust` ensures rock-solid stability and strict OpenAPI 3.2.0 compliance without artificial exceptions.
+
 Unlike traditional generators that blindly overwrite files or dump code into "generated" folders, `cdd-rust` understands
 the Abstract Syntax Tree (AST) of your Rust code. It uses `ra_ap_syntax` (the underlying parser of **rust-analyzer**) to
 read, understand, and safely patch your existing source code to match your OpenAPI specifications (and vice-versa).
