"reviewQuestion": "Do skin texture, face edges, ears, jaw, hairline, and neck transition into the target scene without a pasted-on boundary?", "sampleGuidance": "Inspect high-contrast edges and the full face perimeter rather than only the center of the face." }, { "id": "pose-expression", "label": "Pose and expression coherence", "weight": 14, "mediaTypes": [ "photo", "video", "gif" ], "reviewQuestion": "Does facial geometry remain coherent with the target head angle, gaze, eye state, mouth shape, and expression?", "sampleGuidance": "Prioritize profile turns, closed eyes, open mouths, smiles, and steep head tilts." }, { "id": "lighting-color", "label": "Lighting and color continuity", "weight": 14, "mediaTypes": [ "photo", "video", "gif" ], "reviewQuestion": "Do exposure, color, skin shading, highlights, and shadows remain consistent with the target scene?", "sampleGuidance": "Check directional light, colored light, shadow boundaries, and transitions between bright and dark regions." }, { "id": "occlusion-accessories", "label": "Occlusion and accessory continuity", "weight": 12, "mediaTypes": [ "photo", "video", "gif" ], "reviewQuestion": "Do hair, hands, glasses,

another object." }, { "id": "technical-integrity", "label": "Technical integrity", "weight": 10, "mediaTypes": [ "photo", "video", "gif" ], "reviewQuestion": "Is the output free from material blur, ringing, block artifacts, tearing, duplicate features, abrupt texture changes, or damaged frames?", "sampleGuidance": "Inspect at the intended delivery size and avoid treating deliberate motion blur or depth of field as a defect by itself." }, { "id": "temporal-stability", "label": "Temporal stability", "weight": 10, "mediaTypes": [ "video", "gif" ], "reviewQuestion": "Across motion, does

provider-level claim.", "Report the number of reviewers, samples, runs, viewing conditions, missing ratings, and dispersion rather than publishing one score alone." ], "evidenceBoundary": [ "The score is a structured human observation of one reviewed output, not a biometric identity measurement.", "The rubric does not establish model accuracy, average quality, safety, speed, reliability, or

independent reviewers, documented viewing conditions, and statistical reporting." ], "references": [ { "name": "ITU-R BT.500-15: Methodologies for the subjective assessment of the quality of
