"Canon Keeper is an AI continuity agent for character-driven short videos. Give it a character bible and a one-line premise: Muse Spark plans a 9:16 storyboard, Muse Image renders each frame anchored on reference sheets, then Muse Spark visually checks every frame against each canon rule (MUST / NEVER). Off-model frames get a targeted repair edit and are re-judged automatically; anything still failing is flagged for a human, never silently shipped. It also audits signage: SAM 3.1 finds every floor plaque, Muse Spark reads each one three times by consensus (Muse Wonder breaks ties), and the result is checked against a brand dictionary for typos, wrong floors, duplicates and missing names."
