okf-authoring

Nineteen imperative rules for writing and editing OKF concept files under a config: what is required, what to never touch, the actor and timestamp conventions, and where core's leniency differs from the spec's prose. Use when creating, editing, or reviewing a concept file's frontmatter or body inside an okf/ bundle. Trigger phrases -- "write a new concept", "add frontmatter to this file", "should I set verified", "can I edit index.md", "what actor string do I use", "is generated.at required".
