Workflow

  1. Start with the reference file that matches the question.
  2. Prefer the most relevant file under docs/ for exact instructions and prose guidance.
  3. Use schemas/ and examples/ for exact contracts, payloads, manifests, requests, and snippets.
  4. Do not add behavior or configuration that is not present in the attached source files.
