Arch Gap

Quality score: 80/100 · Category: Product · Sub-category: product-misc

TOGAF-style architecture gap analysis: traces Baseline (AS IS) and Target (TO BE) architectures, builds a Transition plan via TDD, and produces a Gap Matrix with risks — all formatted as product-level descriptions. Each phase uses a domain engine (/tracing, /tdd, /ui) with /describe as the universal output formatter. Use when: planning a feature, refactoring, migration, or investigating a systemic issue.
