The Data Foundation
Imagine receiving a complete list of voter records every month. Each file tells us what the system looked like at that moment.
📁 Aug 2024
📁 Sep 2024
📁 Oct 2024
📁 Nov 2024
📁 Dec 2024
📁 Jan 2025
📁 …
📁 Aug 2026
📁 Sep 2026
If we simply replace August with September, we know what is true now but lose part of the story. The system should instead preserve every relevant state of the record.
