+# Invite-only membership enrollment
+
+New cooperative membership enrollment is invite-only: the public join page explains membership, but the Stripe checkout is hidden unless the visitor has an invite access key. This keeps membership from being fully open while still allowing invited doulas to complete payment without an admin-only manual workflow.

+## Relationships
+
+- A **Family** uses **Doula Discovery** to find doula support
+- A **Match Request** includes one or more **Support Needs**
+- A **Match Request** may include a **Due Date**
+- A **Match Request** may include a **Birth Location** when birth doula support is requested
+- A **Match Request** may include **Cost Offsets**
+- A **Match Request** uses ZIP Code to understand the Family’s **Service Area**
+- A **Match Request** is shared with **Member Doulas** through a **Request Broadcast**
+- A **Member Doula** may have zero or one **Published Doula Profile**
+- A **Published Doula Profile** requires active cooperative membership
+- A **Doula Profile** belongs to exactly one **Member Doula**
+- A **Doula Profile** lists zero or more **Professional Services**
+- A **Support Need** may map to one or more **Professional Services**, but not every **Professional Service** is a **Support Need**
+- A **Doula Profile** may display **Credentials**
+- A **Doula Profile** may display a **Practice Name**
+- **Doula Profile** contact information connects a **Family** directly with the doula or practice
+- **Doula Discovery** includes **Doula Search**, **Directory Browse**, and **Match Requests**
+- A doula-support message should become a **Match Request**, not a **General Inquiry**
+- The **Membership Join Page** currently uses **Invite-Only Enrollment**
+
+## Example dialogue
+
+> **Dev:** "If a Family selects postpartum doula support, do we immediately assign them a Member Doula?"
+> **Domain expert:** "No. That creates a Match Request. The cooperative broadcasts it to Member Doulas, and each doula decides whether to contact the Family."
+
+## Flagged ambiguities
+
+- "tag" appears in Hugo templates and front matter for **Professional Service**; resolved: tag is the implementation term, Professional Service is the domain term.
+- Footer copy says "Browse Members" for professional service links; resolved: these links browse doulas by **Professional Service**, not cooperative members.
+- **Request Broadcasts** currently happen in the private Facebook group; future Members App support is possible but not decided.
