Module improve 

Artifact improvement (decided.services.improve): deterministic, schema-driven guidance. Advisory and read-only — reports missing required/recommended sections with schema-defined guidance questions.

Structs

ImprovementResult

Typed improvement analysis (ImprovementResult). Section names are stored normalized; the renderers format them.

Functions

improve_product

improve_product(product) — analyze and return improvement guidance.

supports_improve

supports_improve(spec) — every expected section defines guidance. (All five current specs pass, so the unsupported branch is dead in practice; ported for fidelity.)
