Preludio · implementation evidence

Useful AI needs a safety boundary.

Preludio helps a clinician prepare a child for a blood draw with a tailored voice story. The model drafts prose within a clinician-authored structure and explicit validation rules.

What the product enforces

Five controls in the live workflow

  1. A constrained clinical input

    The clinician selects one supported procedure, an age tier, language, and a concern. The product does not diagnose, screen, or measure a child.

  2. Clinician-authored source material

    Required facts, truthful sensory details, and seven fixed story beats come from the procedure template—not from the model.

  3. A validation gate before approval

    Every generated story is checked for required coverage, age-appropriate structure, required sensory-detail fields, prohibited content, and false reassurance before it can be approved.

  4. Human approval before delivery

    A user explicitly approves the narration before audio preparation and the parent-facing delivery flow begin.

  5. A deliberately narrow parent link

    The parent view is read-only, has no editable controls, uses an opaque identifier, expires after 24 hours, and shows the approved story transcript and audio.

Demo path

A reviewable, end-to-end interaction

Load a validator-approved English or Spanish example in the clinician flow, review each narration beat, test a proposed override, then approve to prepare and play the narration. The page demonstrates the gate before any parent-facing delivery step.
