# Proposal: Support Organization Members

## Summary
Update the member data model to support both individual persons and organizations. Organizations will have a company name instead of a mandatory first name.

## Background
Currently, the system only supports individual members with a mandatory first name. We need to accommodate organizational members (companies, associations, etc.) where the primary identifier is the organization name.

## Goals
- Allow distinguishing between individual and organization members.
- Make `first_name` optional for organizations.
- Add `company_name` field, mandatory for organizations.
- Ensure data integrity based on member type.

## Non-Goals
- Complex hierarchy of organizations and contacts (for now, just a simple distinction).

## Technical Note
- Field name: `memberType` (not `kind` to avoid GraphQL introspection conflicts)
