A substantial share of modern datacenter spend lives not in raw compute but in the transport between layers: traffic shaping, retransmissions, multi-region egress, inefficient routing, and capacity provisioned to absorb the variance these create.
Our hypothesis is that targeted, observable optimization of OSI-layer-4 transport behavior — under a governance discipline that refuses to hide regressions — can produce measurable, recurring cost reduction in typical multi-region architectures. The size of that reduction is currently awaiting source. Anything more specific than that, on this page, would be theater.
Note on naming: throughout this page, "Layer 4" refers to the OSI transport layer (TCP/UDP). It is unrelated to Layer 4 Obelisk, which is our terminal verification gate.
