Deploys 9-phase systematic architecture decision framework: requirements definition, technical debt analysis, pattern research (microservices/event-driven/serverless/multi-tenant), quantitative scalability modeling, STRIDE threat modeling, trade-off evaluation, C4 target design with testability requirements, strangler-fig migration roadmaps, and TDD POC validation. Produces ADRs, cost models, security assessments, and migration plans. Required for: major architecture overhauls, monolith-to-microservices migrations, cloud/database selection, 10x-100x scale decisions, critical performance/security fixes, or systematic architecture documentation demands.
