  "_comment": "Prototype declared-trace sidecar for docs/history/roadmap/0.6.0-scxml-provider-design.md's next-action step 2/3. Candidate format: a SEPARATE file alongside the .scxml document (not inline in authoring Markdown, not an XML processing instruction inside the .scxml itself -- see the design doc's updated Maturity section for the reasoning). JSON chosen over YAML for this prototype only to avoid a new stdlib-adjacent dependency (PyYAML is not a literate-ai dependency today); a real implementation could reasonably choose YAML for authoring ergonomics -- that is a separate, smaller decision from the placement decision this file is prototyping.",
