FAQPage Schema
How do I validate governance compliance before starting implementation?

Phase -1 Gates enforce governance compliance by validating Constitutional Articles and pre-implementation gates across requirements like library-first architecture, CLI interfaces, test-first approaches, EARS format, and traceability. Run gate validation before coding to catch steering, EARS, and library-first violations early.

What checks does Phase -1 Gates perform on a project?

Phase -1 Gates validates nine Constitutional Articles including library-first requirements, CLI interface mandate, test-first imperative, EARS format compliance, traceability setup, project memory structure, simplicity gates, anti-abstraction rules, and integration-first testing. Each check produces auditable outcomes with 100% traceability.

Can I automate governance compliance checks in my development workflow?

Yes. Phase -1 Gates provides automated validation with remediation planning and reporting for pre-implementation governance checks. It integrates into project setups to enforce traceability and ensure gate outcomes are auditable before implementation begins.

What's the difference between Phase -1 Gates and post-implementation compliance?

Phase -1 Gates operate before implementation starts, catching governance violations during the steering and planning phase. This prevents costly rework by validating EARS format, traceability requirements, and architectural constraints upfront rather than after code is written.

Do I need existing project memory or documentation to use Phase -1 Gates?

Phase -1 Gates includes project memory as a validation checkpoint. It validates whether your project structure supports traceability and memory management. Setup documentation and EARS specifications are prerequisite inputs for gate validation to succeed.

How does Phase -1 Gates ensure 100% traceability?

Phase -1 Gates enforces traceability by validating Constitutional Articles that mandate traceability setup before implementation. It produces auditable gate outcomes and remediation plans, ensuring every governance requirement links to implementation decisions.
