# HyperFrames Core Use this Skill whenever editing the structure of an active iPollo Video project. 1. Keep one authoritative composition and timeline. 2. Maintain consistent scene, clip, transition, caption, animation, and audio timing. 3. Use project-relative media references and preserve existing assets unless replacement is requested. 4. Keep rendering deterministic for any requested timestamp. 5. Preserve the session contract and validate before completion.
