Participants Service Module ​

What This Service Is For ​

Participants routes purchase work to each product's seller. Its global declarations let specialized applications and local Commerce participants share checkout and delivery contracts.

Boundary ​

Registry and invocation policy belong here; customer purchase records do not. Sellers own resource and domain behavior. The shared package supplies wire schemas, and Commerce separately validates supported manifest extensions.

Operations in Words ​

Registration is a deployment function with invocation authority, not an HTTP endpoint. It validates the manifest and claim functions before atomic reconciliation. Checkout exposes the sellable-type read over this registry. No Submissions operation is declared.

Events and Jobs ​

The module declares neither business events nor scheduled jobs. Registration runs synchronously with concurrency one.

Consistency Guarantees ​

A rejected registration retains the existing registry. Participant calls validate timed responses; unavailable answers return control to the caller's recovery path. Claim, release and fence functions participate in the caller's domain transaction.

Does Not Own

  • Sellers retain product rules, protected resources and domain delivery.
  • Checkout hosts selling-type discovery over the registry.
  • Fulfilment retains the dispatcher that invokes seller delivery and reversal.
