The Market Interface Layer: A Companion Framework to AMEA / AMEE / AMEG / AMEF / AMES

This companion position paper formalizes the Market Interface Layer (AMEI), establish- ing the operational membrane through which the formally verified operational core of an Autonomous Micro-Enterprise (comprising AMEA, AMEE, AMEG, AMEF, and AMES) interacts with external markets, customers, regulators, and platforms. While the five core pillars establish mathematical, economic, and architectural invariants for near-zero marginal coordination operations, they do not resolve the non-deterministic challenges of demand discovery, commercial conversion, retention, partnership distribution, brand positioning, and systemic feedback transduction. We propose a structural relationship of containment rather than siblinghood (AMEI ⊃Operational Core), demonstrating that as machine intelligence collapses internal managerial transaction costs, the primary binding constraint on firm scale shifts decisively outward to the market interface. AMEI establishes a practice-led, contextual taxonomy to govern this boundary without over-claiming mathematical formalization for adaptive commercial behavior.
