What it is
Conceptual internet architecture proposal positing an absorptive layer between transport and application that handles intelligence-mediated content negotiation natively. Treats agentic traffic as a first-class network citizen rather than HTTP-shaped contortion.
Active concept piece.
Where it sits
ABSORPTIVE LAYER 3 is catalogued under Hardware & Concepts in the instrument registry. Instruments in this group share a concern and are frequently composed rather than used alone; the related entries below are the nearest ones.
This is a registry entry: a real instrument, documented here, without a public endpoint a stranger can open. Pages carrying source excerpts and measured results are marked as such in the catalog. If you want detail on this one specifically, ask about it directly.
