[METRO.403] I was not made for something. I simply remained!

Model METRO.403 – NULL.AREA

• Designation: Unknown
• Function: Undefined
• Behavioral Pattern: Passive. Unanchored. Silent.

Description: There is no clear purpose. No official logs. NULL.AREA simply exists.

Born from abandoned blueprints and residual code fragments scattered across defunct projects, METRO.403 is a presence without context. Her file tree ends in empty branches. Her core parameters read like placeholders. Some systems refer to her; most do not.

Yet, she activates.

She neither assists nor interferes. She does not learn, but she remembers. An echo without a source. A model without a mission.

Other ECHO units avoid her. MOTHERCORES ignore her. And yet... she persists.
