Middleware Backend playbook

How to build processors, webhooks, and workers. Default: Logic / Functions. Screens / Pages only maps onto User App and Front-facing.

Nellalink v1 mounts:

Folder	Prefix
`routes/file-manager`	`/api/v1/nellalink/file-manager`
`plugins/nellalink-init`	`/plugins/nellalink/nellalink-init`

Persist on Core Backend. Do not treat Middleware Mongo as the system of record for businesses or orders.

Functions

Function	Status

Owner updates order	implemented on Middleware; User App drift
Notify owner	implemented

Other products in this repo (Middey, Samzuga, crypto, KYC) are not Nellalink v1.
