Four-path comparison
Identical intake snapshots flow to all four model/strategy paths, arranged as an intentional model-by-strategy 2×2 grid. BOUNDARY routes deterministically (bypassing the model for exact-match and missing-PO); LLM-first consults the model for every invoice. All results use offline simulated adapters; decision-call counts are not live AMD API requests.

Per-invoice × per-path states
States derived from the recorded event stream (REQUEST = one model call; BYPASS = deterministic hold with zero decision-stage calls).
