Evidence claims:
- [sourced_fact] Page documents Version 1.0 (labelled Latest; 0.4 linked as older). Top-level version must be 1; nodes and state are required; nodes carry id, type, pos, size, flags, order, mode, inputs, outputs, properties, widgets_values; links, groups, config, reroutes, extra and models are also defined. · source: https://docs.comfy.org/specs/workflow_json
- [sourced_fact] Schema is defined inline as JSON Schema draft-07 and the page points to github.com/comfy-org/rfcs for proposed schema changes. The page does not describe differences from the API (prompt) format. · source: https://docs.comfy.org/specs/workflow_json
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
