GSD Preflight Validator

Pre-flight checks on .planning/ artifacts to catch issues before workflows fail.

Core Artifact Checks

PROJECT.md — Sections: What This Is, Requirements, Constraints, Key Decisions ROADMAP.md — Sequential phase numbers, each with Goal/Deliverables/Success Criteria STATE.md — Current Position matches ROADMAP status, reasonable progress % config.json — Valid JSON, valid enum values (mode, model_profile, depth)

Cross-Artifact Consistency

• STATE.md phase exists in ROADMAP.md
• Completed phases have matching SUMMARY files for each PLAN
• Phase directories exist for all ROADMAP phases
• No orphaned files (PLAN without phase, SUMMARY without PLAN)
