Observer-Patch Holography · application network

One framework.
Four machines.

OPH treats physics as the public fixed-point of finite observers agreeing on overlap-visible data. That single bookkeeping rule turns out to power computation, propulsion, intelligence, and energy release. Start with the principles, then pick an application.

Status legend · modeled dataset live means visualizations run on a pre-hardware computed dataset. Draft means the explainer and "why it works" derivations are written; interactive visualizations are next.
