integration API

integration is part of Luna-Flow/calculus-numerical. This page should describe the public types, constructors, functions, traits, and observable semantics that are implemented in the current branch.

Scope

• Source boundary: src/integration
• Audience: package users, integrators, and maintainers who need the exported contract
• Status: active

Public Contract

• Describe only exported behavior that exists today.
• Call out backend or subtype differences when they are observable.
• Keep naming, argument ordering, and error semantics aligned with sibling modules when possible.
