CharacterOS is the runtime behind every surface. It reads the manuscript, learns the cast from the text, and carries that understanding forward so each step inherits the same story logic.
That ordering is the whole point. Understanding comes first, then generation. The principles below are not product promises. They are the constraints that determine what gets built, what gets deferred, and what never ships.
The manuscript is the source of truth
Every character, scene, and audio step starts from what the story actually says. Generation follows understanding, not the other way around.
Characters stay in bounds as the story comes alive
CharacterOS keeps character profiles, relationships, timeline, and voice grounded in canon so every downstream step inherits the same story logic.
Review happens before the expensive steps
Continuity checks, scene approvals, and quality scoring keep story quality visible before voice, audio, or export ever enter the picture.
