Direct Image — FAST vs FULL

FAST (Partial, Preview Hidden)

{
  "processing": { "status": "partial", "completion": 0.5, "enrichmentsPending": true,
    "completedStages": ["semantic", "mediaFormat", "metadata:image"],
    "pendingStages": ["preview:thumbnail", "preview:blurhash", "preview:palette"] },
  "data": {
    "identity": { "mime": "image/jpeg" },
    "semantic": { "kind": "direct-media", "semanticType": "image" },
    "metadata": { "filename": "god_16.jpg", "size": { "bytes": 204800, "formatted": "200 KB" } }
    // preview: projection-hidden
  },
  "projection": { "profile": "fast", "hiddenFields": ["preview"] }
}

FULL (Complete, All Enrichments)

{
  "processing": { "status": "complete", "completion": 1, "enrichmentsPending": false,
    "completedStages": ["semantic", "mediaFormat", "metadata:image", "preview:thumbnail", "preview:blurhash", "preview:palette"],

Key Difference

FAST omits preview entirely (hiddenFields: ["preview"]) because these are generated enrichments for direct media. FULL includes everything with complete enrichment data.
