# Supply and matching model

> Understand ActionX supply sources, retrieval logic, and result delivery model.

This page explains where ActionX results come from and how they enter the decisioning flow.

    supply["Supply<br/>Products<br/>Programs<br/>Affiliate sources"] --> decision["Decision<br/>Intent<br/>Retrieval<br/>Ranking"]
    decision --> output["Output<br/>Action card<br/>Suffix<br/>Entity link"]
```

## Where supply comes from

* `product-feed`: product feeds, affiliate products, and semantic retrieval results
* `partner-stack-feed`: SaaS programs, partner projects, and entity matching results
* Other candidate sources orchestrated by `ads-server`

## How the platform matches

* First, understand user intent and entities
* Then retrieve candidates from multiple supply sources
* Finally, determine the result using relevance and platform policy

## What to focus on in the diagram

* Left: supply sources
* Middle: decisioning and ranking
* Right: the result form users ultimately see
