spec-kitty-mission-system

Understand how Spec Kitty missions work: the 4 built-in mission types, how they define workflows via step contracts and action indices, how missions and work packages relate, how templates are resolved through the 5-tier chain, and how doctrine artifacts (procedures, tactics, directives) compose mission behavior. Triggers: "what missions are available", "how do missions work", "which mission should I use", "explain the mission system", "what is a mission", "change the mission", "mission templates", "step contracts", "action index", "mission procedures". Does NOT handle: runtime loop advancement (use runtime-next), setup or repair (use setup-doctor), governance (use charter-doctrine), or glossary curation (use glossary-context).
