Correspondence

Write to us with the hard question

The most useful message we receive is the one that tries to break the thesis. If you build hardware, run a laboratory, or have read the 1984 mechanism more carefully than we have, we would rather hear it now than after the experiments.

Where to send it

Two addresses, one ledger

Technical correspondence

Physics, measurement design, objections to the experiment plan, offers of instrument time.

compute@vivovac.example

Commercial and partnership

Systems that would host an analog-weight layer beside silicon, and manufacturing partners on the anodising side.

Placeholder details. These two addresses and the postal city below are stand-ins — send us the real ones and we will put them in.

What to expect

What we will and will not send back

We will send

The experiment plan in full, the sources list, and the ledger sheet as it stands on the day you ask — including the rows that have not gone our way.

We will not send

Anything from the sensing ledger, any performance figure that does not exist yet, and no projection dressed as a measurement.
