od-figma-migration (scenario)

Spec §1 / §10.1 / §21.3.1 / §23.3.3: the canonical figma-migration flow. The pipeline is sequenced so each stage's output is the next stage's input — figma-extract writes figma/tree.json, token-map writes token-map/colors.json (etc.), and generate reads both before producing the HTML artifact.

Default pipeline

{
  "stages": [
    { "id": "extract",  "atoms": ["figma-extract"] },
    { "id": "tokens",   "atoms": ["token-map"] },
    { "id": "generate", "atoms": ["file-write", "live-artifact"] },
    {
      "id": "critique", "atoms": ["critique-theater"],
      "repeat": true,
      "until": "critique.score>=4 || iterations>=3"
    }
  ]
}

Required GenUI surfaces

The scenario expects two oauth-prompt / form surfaces from the plugin layer:

• figma-oauth — oauth.route='connector', connectorId='figma', persists at the project tier so multi-conversation work doesn't re-prompt.
• file-pick — kind='form', captures the Figma file URL on the first turn so figma-extract knows where to read.

The daemon auto-derives the figma-oauth surface when od.connectors.required[].id='figma' is declared and the connector isn't yet authorised (spec §10.3.1 implicit oauth-prompt rule).
