One row per project and address: re-inviting the same email updates the existing row (role, expiry, token if it had been accepted) rather than adding another. `emailStatus` becomes `undeliverable` when Postmark rejects the address for good (suppressed or malformed) or the queue exhausts its retries; the pending-invitations list shows that to the inviter.

**Note:** Projects are always invite-only. By default, accepting an invitation grants project membership only. The `grantOrgMembership` field can be set to `true` by org admins/owners to also grant organization membership (for governance/billing purposes).

Every project add is an invitation: whether the owner picks an existing user or types an unknown email, the server creates a `projectInvitations` row and emails a link, and membership is only created when the recipient accepts. Direct membership writes are reserved for internal/test tooling (`addMember` command, dev routes).

1. Project owner calls `POST /api/orgs/:orgId/projects/:projectId/invitations` with `{ email, role, grantOrgMembership?, orgRole? }`.
2. Server creates a `projectInvitations` row with a unique token and sends a magic link.
3. Invitee clicks the link, lands on `/complete-profile?invitation=TOKEN`, completes profile if needed.
4. Frontend calls `POST /api/invitations/accept` with the token.
5. Server validates: token exists, not expired, not accepted. The invited email is a delivery address, not an identity check: membership binds to whichever authenticated account accepts the token, so someone invited at an institutional alias can accept from an account keyed to a different address.
6. If `grantOrgMembership === true`, the server adds org membership with `orgRole` (if the user isn't already a member).
7. Server adds `projectMembers` with `role`.
8. Frontend redirects to the project.
1. Project owner calls `addMemberToProject` with `{ userId | email, role }`.
2. Server checks the collaborator quota (non-owner members plus live invitations to people not yet in the workspace count as seats; inviting an existing workspace member takes none), then `createInvitation` applies the send caps from `INVITATION_LIMITS`: at most 20 live invitations per project, at most 30 created per inviter per hour, and one email per address per 10 minutes.
3. Server creates or updates the `projectInvitations` row (one per project and address) and queues an email carrying `/invite/<token>`. The result reports `delivery` as `queued`, `recently_sent` (inside the cooldown, no new email) or `not_sent` (queue failure or an address that cannot take mail); the invite modal's toast reflects it. An account matching the address also gets an `invitation.received` notification.
4. The queue consumer acks a permanently rejected address (Postmark 300/406) without retrying and marks the row `emailStatus = 'undeliverable'`; a dead-lettered message does the same. The pending-invitations list shows "Email could not be delivered" for that row.
5. Invitee opens the link, lands on `/invite/$token`, and signs up or signs in if needed.
6. Frontend calls `acceptInvitation` with the token.
7. Server validates: token exists, not expired, not accepted. The invited email is a delivery address, not an identity check: membership binds to whichever authenticated account accepts the token, so someone invited at an institutional alias can accept from an account keyed to a different address.
8. If `grantOrgMembership === true`, the server adds org membership with `orgRole` (if the user isn't already a member).
9. Server adds `projectMembers` with `role`.
10. Frontend redirects to the dashboard.

Separate email delivery from in-app delivery.

Lines 14-18 define not_sent as always having an in-app delivery path. createInvitation creates a notification only when an account matches the address. For an unknown address and a queue failure, the invitee receives neither email nor notification. AddMemberModal then tells the inviter that notifications provide an acceptance path.

Return an independent notification-delivery flag, or use separate delivery states.

In `@packages/shared/src/email.ts` around lines 13 - 18, Update the
InvitationDelivery contract and the createInvitation flow so email delivery
status is independent from in-app notification delivery: unknown addresses and
queue failures must not be represented as not_sent with an implied notification.
Return a separate notification-delivery flag or distinct states, and update
AddMemberModal to claim an acceptance path only when that flag indicates a
notification was actually created.

Resolve existing duplicate invitations before creating this index.

Line 3 fails the migration if any existing project_invitations rows share the same projectId and email. The prior schema allowed this state. Deduplicate these rows in the migration, with an explicit rule for the row to retain, before creating the unique index.
