Optional branch

A pipeline with one optional fork — review-then-publish, or skip-and-publish. The branch lives in the graph, not in a flag you have to remember to set.

Code

post.fsl

const post = sm`
  draft      'submit'   → reviewing;
  draft      'publish'  → live;       // admin shortcut
  reviewing  'approve'  → live;
  reviewing  'reject'   → draft;
