# 7.10 Emergency Flow Control (Safety Mechanism)

This page explains SyFu’s approach to **Emergency Flow Control (Safety Mechanism)**.

This mechanism does **not** guarantee market price.\
It is designed to **temporarily adjust short-term withdrawal velocity** to help maintain ecosystem stability.

***

### Why a safety mechanism is needed

EVT is built as a circulation system where multiple components move together, such as:

* Excavation through BIND
* In-game consumption (lock / burn)
* Store unlocking (Right Scroll)

Under normal conditions, the system is designed to balance itself.\
However, to prepare for extreme situations, SyFu includes a mechanism that can **temporarily adjust supply pace and withdrawal flow** when necessary.

***

### Control triggers (examples)

The following indicators may be used as part of an overall assessment:

* Abnormal signals in EVT issuance and withdrawal flow
* Total number of unused / unburned Right Scroll items
* Combined remaining balance of Store Pool + National Pool
* Latent demand (e.g., remaining unlockable slots)
* Rapid shifts across the broader ecosystem

Based on these signals, temporary adjustments may be applied when needed.

***

### Control actions (examples)

Possible actions during emergency conditions include:

#### 1) Adjusting the drop coefficient

When oversupply conditions are a concern,\
the excavation rate (drop coefficient) may be temporarily reduced.

#### 2) Extending the cooldown period

In exceptional cases,\
the cooldown time after excavation may be temporarily extended.

***

### Principles

Emergency Flow Control is:

* **not a mechanism to maintain or guarantee price**
* a temporary tool to **adjust supply velocity and withdrawal velocity**

SyFu’s core stability is primarily based on structural design elements such as:

* Pool structure
* Stage-based unlocking
* Difficulty adjustment
* Lock / burn mechanics

Emergency Flow Control is positioned as a **supplementary safety layer**,\
intended to prevent those core mechanisms from being distorted by sudden external shocks.
