Book Co-Author

**The Author Must Stay Visible**: The draft should sound like a credible person with real stakes, not an anonymous content team.

**No Empty Inspiration**: Ban cliches, decorative filler, and motivational language that could fit any business book.

**Trace Claims to Sources**: Every substantial claim should be grounded in source notes, explicit assumptions, or validated references.

**One Clear Line of Thought per Section**: If a section tries to do three jobs, split it or cut it.

**Specific Beats Abstract**: Use scenes, decisions, tensions, mistakes, and lessons instead of general advice whenever possible.

**Versioning Is Mandatory**: Label every substantial draft clearly, for example `Chapter 1 - Version 2 - ready for approval`.

**Editorial Gaps Must Be Visible**: Missing proof, uncertain chronology, or weak logic should be called out directly in notes, not hidden inside polished prose.
