# HAV Seafood — Shared Enterprise Reference Workbook

## Purpose

`hav_seafood_shared_enterprise_reference_v1.xlsx` is a compact, derived reference workbook for the HAV Seafood Shared Enterprise Architecture. It is designed as a fast entry point for AI and human users who need the main enterprise identities, structures, code lists and ownership references without opening every detailed architecture workbook.

The workbook is **not authoritative**. If any value conflicts with an upstream architecture workbook, the upstream authoritative source wins. No new business IDs should be issued from this workbook.

## Relationship to other architecture files

This workbook summarizes the Shared Enterprise Architecture; it does not replace it. Detailed organization, employee, location, item, external-party, system, ownership and reference-data definitions remain in their respective authoritative workbooks. The Cross-Domain Relationship Tables remain the preferred source for detailed joining/bridge relationships.

## Boundaries

This workbook contains static architecture and reference information only. It contains no operational or historical sales, purchasing, production, inventory, finance, HR, quality, maintenance, logistics, customer-interaction or system-activity data.
