"""Add consumer_inbox table for outbox idempotency.
|

|
|
|

|
|
Revision ID: 0065
|
||
|
|
Revises: 0064
|
||
|
|
Create Date: 2026-07-29
|
||
|
|
|
||
|
|
Without idempotency, a worker crash between sending an email/webhook
|
||
|
|
and marking the event as published can lead to duplicate deliveries.
|
||
|
|
|
||
|
|
This migration creates a consumer_inbox table that tracks which
|
||
|
|
consumers have already processed which events.
