    "evidence": "Across the six keys the same asymmetric funnel remains identifiable: open polygonal spiral at the crown, projecting upper tail, right-side overlap, angular taper, and pointed tip. The held road-and-pole background is compatible with the selected source setting."
  },
  "poses": {
    "verdict": "uncertain",
    "evidence": "The keys show modest width and bend changes, with a broader middle pair and a narrower last key. These are plausible funnel variations, but the still sequence does not clearly communicate the source progression in funnel mass and shifting lower column; most keys read as almost the same upright funnel."
  },
  "biggest_gap": "Source-linked phase distinction is too subtle to judge confidently from the six still keys.",
  "smallest_repair": "Retain the exact crown, overlap, angular contour vocabulary and tip, but make one or two source-observed changes in lower-column lean and width clearer at their corresponding keys. Keep the held road background.",

    "Exact angular funnel construction",

  "scope": "Only design.png, first six board-v1 tiles and held-background tile seven, selected 16-frame and six-key source contact sheets were inspected. No rendered motion was reviewed."
