1. Intermediate output moves to the next consumer

- Compare buffer contents with their arrival and consumption rates.

## How it works

Buffers store differences between arrivals and consumption, absorbing brief disruptions without raising sustained line capacity.

## Variants

### Mechanic variants

<a id="t109-variants"></a>

- Storage limits stop an upstream stage. <a id="t109-v1"></a>
- Inventory smooths irregular deliveries. <a id="t109-v2"></a>
- Batch thresholds combine small arrivals. <a id="t109-v3"></a>
- Overflow redirects surplus to an alternate output. <a id="t109-v4"></a>

## Design example

Storage absorbs a brief delivery gap but drains under a persistently undersized extractor.

Prototype check: Test that indicators distinguish temporary inventory from the actual throughput of the limiting stage.

## Context and limits

Automation moves repeated work into a system; the player builds connections and identifies the limiting stage. Each overview separates player actions, state changes and alternative rules. Examples are hypothetical design scenarios, not claims about a named game. A prototype check states an observable question for the next iteration. Existing detailed references remain separately linked from the direction map.
