"""per-user notification inbox (phase 1)

Revision ID: 0017_notifications

Revises: 0016_video_maintenance

Create Date: 2026-06-18
|
||
|
|
|
||
|
|
Adds the durable, server-backed per-user notification table behind the inbox module. The
|
||
|
|
JSON payload column is named `data` (SQLAlchemy's declarative Base reserves `metadata`).
|
||
|
|
First producer is the maintenance job's batched "videos removed" notice. Coexists with the
|
||
|
|
existing client-side transient bell.
