# Lesson 3 complete: strategies & SW pairing

Learner finished lesson 3: warehouse vs policy, install/activate fill/cleanup, and choose among cache-first, network-first, SWR, network-only, cache-only. External primaries (Offline Cookbook; SW vs HTTP caching) remain optional/unread. Next ZPD: deal-breakers and design-review rejection skills (versioning, opaque responses, dual-cache fights, quota/eviction, wrong-tool) — then decision playbook as mission payoff.
