cratefield-module-orgs

Organizations, memberships, roles and email invitations for a Cratefield venture: a person creates an organization and is its owner, invites people by address, and everyone who belongs holds a role the venture configured.

Mounted at /v1/orgs. One migration, three tables. Every route but the admin listing acts for the account the venture's Auth port identifies; no route reads a subject id from anywhere else, so one person cannot act as another.

Composing it

use cratefield_module_orgs::Orgs;

let orgs = Orgs::builder()
    // `owner` is always in the set and is the creator's role.
    .roles(["owner", "manager", "staff"])
    // Non-owner roles that may manage members and invitations.
    .managers(["manager"])
    .build();

Configuration keys (all prefixed ORGS_):

The rules

• An organization always has at least one owner. The last owner cannot leave, be removed or be demoted — each is one guarded statement whose affected-row count decides it, answered with 409 orgs-last-owner.
• Owners may do anything. A manager role may add, remove, re-role and invite, but only an owner may grant or revoke the owner role and only an owner may change an owner's membership.
• A caller who is not a member gets the 404 orgs-not-found an unknown id gets, so organizations cannot be enumerated.
• An invitation stores only the SHA-256 of its token and of the invitee's normalized address, and is spent by one guarded UPDATE: a second accept, or one from the wrong address, finds it already gone. The raw token is mailed, never returned in a response.

Typed API

// May this person see this organization's page?
let role = cratefield_module_orgs::member_role(&*db, org_id, &subject).await?;

// May this caller use an admin route?
let staff = cratefield_module_orgs::require_staff(&ctx, &headers, staff_org, &roles).await?;

Moving from ADMIN_TOKEN to a staff org

require_staff and the admin listing accept either a machine holding ADMIN_TOKEN or a person whose verified subject is a member of the staff organization holding one of the staff roles. A deployment that has an ADMIN_TOKEN keeps working unchanged; the staff organization is the path for people.

To move:

1. Compose the module with .roles([.., "admin"]).staff_org("<org id>").staff_roles(["admin"]). A staff role configured without a staff organization is a self_check failure, because nobody could ever hold it.
2. Create the staff organization in the venture and give the people who should have access the staff role there. Nothing else changes: membership is grantable and revocable through the ordinary routes.
3. Once no machine needs ADMIN_TOKEN, remove it. Every admin route then answers 401 unless the caller is staff.

No shared secret to rotate, and removing somebody from the staff organization is a DELETE — that is the reason to move.

Ports

Requires Db and Auth. Optionally uses Clock (expiry and single-use), IdGen (ids and the invitation token) and Mailer. A mailer that reports NotConfigured leaves no invitation behind: the row is deleted and the caller gets the same 503 mail-not-configured the waitlist form degrades on.

Personal data (ADR 0015)

An organization outlives its creator — deleting the row would delete every other member's organization with it — so orgs is retained, with the reason published in the manifest. A membership is the member's, and erasing their account removes it.
