Mission Run Overview
Mission Run: Common Docs query — CLI retrieval index
Give agents and harnesses a first-class 'spec-kitty docs query --json' retrieval surface over Common Docs (title + heading-anchor + abstract index), closing the one canonical-knowledge gap that still requires ad-hoc file globbing.
Charter, doctrine, and glossary already expose --json retrieval; Common Docs is the last canonical knowledge home with no query API. This mission adds a generated, freshness-gated docs index + a glossary-shaped query CLI, reusing the existing inventory_lockfile generator/gate + the glossary query pattern rather than new infra.
