Authoritative settings that should not be changed after locking.

• world.json - World rules, systems, stakes, setting
• characters.json - Character desires, fears, beliefs, arcs
• conflict_graph.json - Conflict nodes, edges, sets
• style_card.json - Narrative voice, prose style

Workspace Layer (workspace/)

Draft area for experimentation.

• drafts/ - Draft content
• experiments/ - Experimental variations
• notes/ - Research and notes
• plot_variants/ - Plot versions (plot_v001.json, etc.)

Publish Layer (dist/)

Generated output for sharing.

• index.html - Version index
• plot_v001.html - Plot page
• runtime.json - Interactive mode config
