Lean Composition Capability Matrix
Author direction
Design the Composition Engine so it selectively combines useful capabilities from existing writing systems while using a reasonable amount of model usage.
Result
The proposed design is recorded at 07 Coordination/Authoring System/05 - Prose Capability Matrix and Usage Routing. It uses one default model pass, deterministic checks first, risk-triggered specialist escalation, bounded context, and a maximum revision budget. It does not run every available writing skill against every scene.
Governing constraint
Quality is measured against author approval and story integrity, not number of agents, critiques, or tokens consumed.
Author decision — first vertical slice
The author approved the outcome-presentation confrontation as the first vertical-slice scene. Samuel attempts to offer Sylvan a customized version of the bargain that trapped Konrad while Konrad's inner circle can compare Samuel's claims with reality.
