"""Push subscriptions table for Web Push notifications
|
|
|
|
Revision ID: 012
|
|
Revises: 011
|
|
Create Date: 2026-03-26
|
|
|
|
Creates the push_subscriptions table so the gateway can store browser
|
|
push subscriptions and deliver Web Push notifications when an AI employee
|
|
responds and the user's WebSocket is not connected.
|
|
|
|
No RLS policy is applied — the API filters by user_id at the application
|
|
layer (push subscriptions are portal-user-scoped, not tenant-scoped).
