"""Minimal CatOpt bridge scaffolding for NovaPlan.
|
|
|
|
This module provides a tiny, domain-agnostic scaffold to map NovaPlan MVP
|
|
primitives to a CatOpt-like representation. It is intentionally lightweight and
|
|
intended for experimentation and integration in MVP milestones.
|
|
|
|
- Object: canonical local problem representation (LocalProblem).
|
|
- Morphism: exchange vectors such as SharedVariables and PlanDelta with versioning.
|
|
- Functor: adapters that translate device-specific planning representations into the
|
|
canonical NovaPlan form.
|
|
|
|
Note: This is a stubbed scaffold and not a full implementation. Real adapters
|
|
and a transport layer would be built on top of this in Phase 0/1 milestones.
