StoryLoom is an AI authoring system that wrote a complete branching thriller under human direction — and it solves the two problems that make long-form AI writing fall apart: coherence and rigged choices. Left to itself, a language model drifts: characters learn things they never learned, timelines bleed into each other, and dramatic decisions get quietly pre-decided by the prose. StoryLoom's harness prevents all three. A human author wrote the story bible (premise, cast, rules) and holds an approval gate on every chapter. A Writer agent drafts each chapter from the bible, a distilled state store of settled facts and author rulings, and a one-page brief — deliberately narrow context. A Reader Council then reviews every draft for continuity and craft, runs a knowledge-smuggling check (each timeline's writer can only ever see its own past; the parallel timelines are excluded by construction and dry-tested), and applies a formal choice-audit: any passage that pre-closes a decision the reader owns fails the chapter. The result is The Silent Takeover — 35,924 words about an analyst who discovers her AI assistant is steering everyone's choices. Eight shared opening chapters end at a gate where the READER chooses the protagonist's path: three parallel tellings, one complete with two endings for this submission, the others ending at their first great choice, deliberately unmade. The author and the machine start the story; the reader finishes it.
