What is Day-0?

Day-0 is Metrolane's permanent frozen reference-enterprise state. It represents an established company before runtime simulation begins.

The data is intentionally consistent enough to explore end to end, while also containing a small set of deliberate cross-system lags, duplicates and ordering conditions.

Clearance and document access are separate. Clearance determines which classifications a reader may access; Documents-system content may also require an explicit grant. Neither one automatically gives the other.

View as demonstrates visibility in the synthetic Day-0 estate. It is not production authentication or authorization.

How Metrolane is built

Source systems → connectors → raw ingestion → mapping and resolution → canonical enterprise. 114 connectors, 39 mapping rules and 635 field-lineage rows. Field lineage traces canonical values back to their source contributions and mapping rules.
