Sidelist relay

There is nothing to see here, and that is deliberate. This is a sync relay — the piece that lets two phones share a list when they are rarely switched on at the same time.

It holds encrypted blobs and passes them along. It cannot read them, and neither can whoever runs it: everything arrives already sealed by the device that wrote it, signed by a key this server never possesses. That is the point of the design rather than a promise about our good intentions.

If you were looking for the app, you want it on your phone — this address is only ever spoken to by software.

Devices talk to /space/{id}/ops. Everything else lands here.
