# Course closed at decision playbook

Learner finished lesson 0005 (decision playbook). Mission success criteria are met via lessons 1–5 + references: choose store family, know Request/Response warehouse shape, name SW strategies, spot deal-breakers (versioning, opaque, dual-cache, quota/Safari), and defend the package in a design-review sentence. Path was lesson-first; external web.dev/MDN primaries remain optional enrichment, not blockers. Track closed for issue #2 unless learner opens a follow-up (Workbox, hands-on SW, or a real product brief).
