Authority Forge 12 category TDD architecture

The problem

Standard TDD is often bypassed by developers who write tests after the implementation or create weak assertions that don't actually catch bugs. Manual code reviews struggle to verify if a test suite is truly resilient against edge cases and tampering.

What it does

• Enforces a strict Red-Green-Refactor cycle by cryptographically locking test files with SHA-256 Merkle trees before implementation begins.
• Identifies and freezes 12 critical enterprise risk domains, including multi-tenant isolation, TOCTOU race conditions, and fault injection.
• Performs automated AST and regex semantic mutation testing to ensure tests actually kill bugs, requiring a 90% kill rate for certification.
• Strictly enforces Rule 8, rejecting any source file exceeding 350 lines of code to maintain modularity and readability.

Frameworks & tools

Polyglot support for Node.js, TypeScript, Python, Go, Rust, and Java. Uses a self-contained Node.js gate engine with zero external dependencies.

Why this beats prompting it yourself

Generic prompts cannot enforce cryptographic integrity or perform real-time mutation analysis. This skill provides a machine-gated protocol that prevents "test-after-code" cheating and issues verifiable evidence badges that prove code quality through math, not just intent.

Use cases

• Hardening financial transaction logic against concurrency and double-spend errors.
• Ensuring multi-tenant SaaS applications maintain strict data isolation boundaries.
• Automating high-integrity PR reviews where machine-certified evidence is required for merge.

Known limitations

Requires a Node.js runtime for the gate engine. Source files are strictly capped at 350 lines of code; larger legacy files must be refactored to pass.
