AgriFlow Matching Engine
=========================

Public API untuk matching engine 3-lapis.

Quick start:

    from matching_engine import run_matching, SupplyNode, DemandNode, ...

Architecture:
    Layer 0 (constraints.determine_tier)     → Data confidence tier
    Layer 1 (constraints.generate_candidates) → Hard constraint filtering
    Layer 2 (scoring.compute_score)          → 5-dim multi-objective scoring
    Layer 3 (allocation.allocate)            → Stable matching atau Greedy

See engine.run_matching for the main entrypoint.
