The story header

The header names the story and carries its identity fields. story and the quoted title are required if a header is present at all; by is optional; the indented lines below are free key: value fields, of which id, version, and blurb are the conventional set. The header may also own story-wide states and scores, using the same two line forms every other owner uses:

story "The Walled Garden" by "Sharpee Docs"
  id: walled-garden
  version: 1.0.0
  blurb: A pocket world for the Chord language reference.
  states: daylight, dusk
  score explorer worth 5

The story starts in the first declared state (daylight here), and any behavior body can move it forward with change the story to dusk.
