What problem does it solve? Game projects accumulate duplicate versioned files, stale references, conflicting authority sources, and unverified third-party tool adoptions. This Skill provides a governed lifecycle for installing new project operating systems, auditing existing ones, reconciling legacy artifacts, migrating approved content, and verifying the whole structure with evidence. ## Core Features & Use Cases - Five Skill Modes: install, audit, reconcile-legacy, migrate, and verify, each with explicit read/write boundaries and approval gates so existing projects are never restructured without sign-off. - Workspace Authority Governance: Enforces a repository-first canon with derived human-facing PDFs, treating Notion and Google Sheets as legacy read-only or compatibility-only migration sources. - Third-Party Provider Contracts: Manages HiGodot exact-pin adoption, GUT deterministic testing, and Hera live-QA boundaries with canary, regression, and rollback evidence requirements. - Use Case: After merging a large restructuring PR, run the verify mode to re-read the exact new main, adversarially review the full approved scope, correct findings through new branches, and confirm zero remaining work before reporting completion. ## Quick Start Audit my existing game project repository and produce a legacy file reconciliation table without making any changes.
