Every vendor said the format was technically impossible to export.

Every reading, every mine, one coordinate system — that was the whole pitch.

Six weeks of format archaeology, two days of actual rendering work.

The safety board circled one number in the whole report and asked for it weekly.

The first demo ran on a laptop from the parts bin, and nobody could tell.

We shipped it nine days early anyway.

The whole pipeline fit in 400 lines of Python.

It replaced a workflow that took three weeks per mine with an afternoon.

The readings lived in seventeen different file formats across four vendors.

Nobody had ever measured it at all, as far as we could tell.

One pass over the data, no second chances, no retries.

The client called the demo borderline unsettling, which we took as a compliment.

Two teams, one paging schedule — that was the deal.
