# Designesy — /contracts/motion Canonical page: https://www.designesy.org/contracts/motion --- ## Motion Motion is structural communication, not ornament. If motion files are malformed or violate the non-negotiable standards, they degrade trust, clarity, and usability. Version 0.1.0 · provisional · [machine export](https://www.designesy.org/contracts/motion.json) ## Source authority Lottie Animation Community Specification v1.0.1 (2025-06-26) [https://lottie.github.io/lottie-spec/1.0.1/specs/schema/](https://lottie.github.io/lottie-spec/1.0.1/specs/schema/) ajv 8.20.0 (draft 2020-12 via ajv/dist/2020) + ajv-formats 3.0.1 ## Ten Non-Negotiable Motion Standards ## Verification — 10 checks 10 checks. PASS=1, WARN=0.5, FAIL=0. Score = (points/10) × 100. A≥90, B≥80, C≥70, D≥60, F<60. ## Open questions - Raw schema URL verification: is it lottie.schema.json appended to the schema path? - Reduced-motion marker convention: should Designesy establish "reduced"/"calm"/"static" name? - GSAP scope: should this contract cover GSAP timeline validation or a separate contract? - HyperFrames scope: does the HyperFrames quality gate handle HyperFrames independently? - Lottie spec stability: should validator warn when file uses features outside approved subset?
