Memberships

Last updated:

A membership is the historical relationship between one account and one organization. Only a current membership carries a framework role and can participate in validated organization context.

Warning

The membership-administration operations documented here are accepted public contracts, but their WS-005 implementation and readiness verification are still in progress.

Model

  • MembershipId identifies the relationship.
  • OrganizationId and AccountId are immutable membership ownership values.
  • Current memberships use Owner, Administrator, or Member.
  • Removed memberships are retained as history and grant no authority.
  • One account can have at most one current membership in an organization.

Administration contract

IMembershipApplication defines member listing, invitation listing and issuance, invitation revocation and acceptance, role change, member removal, and ownership transfer. Member and invitation lists use cursor pagination with a default page size of 50 and maximum of 200.

Mutations use opaque version-token preconditions where specified. Stale values return concurrency_conflict.

Invariants

  • An operation cannot mutate a membership owned by another organization.
  • Ordinary role change cannot assign or remove Owner; ownership uses the dedicated transfer workflow.
  • No mutation may leave the organization without an Owner.
  • Self-service organization departure is outside the Initial MVP.
  • Membership and required lifecycle work commit atomically.

Current implementation status

Organization persistence and current-account membership discovery are implemented. Member listing, role change, removal, invitations, ownership transfer, context invalidation, and final readiness evidence remain in progress.
