# Contracts Interface Notes

## Core Contracts

1. Membership contract (soulbound utility access).
2. Offer + entitlement settlement contract (`EdutOfferEntitlement`).

## Required Events

1. `MembershipMinted`
2. `MembershipStatusUpdated`
3. `OfferUpserted`
4. `EntitlementMinted`
5. `EntitlementStateChanged`

## Backend Dependency

Backend must reconcile on-chain events into deterministic membership/entitlement status for runtime gates.
