IBM-II Software Ethernet Surface

This harness treats an IBM-II-class machine as a software Ethernet controller surface. Ethernet is only the local shell. The admitted Omnitoken object is still the two-byte scale-invariant LUT selector:

u8 domain
u8 scalar

The controller emulates constraints that matter for old/small machines:

  • four-slot RX ring
  • 160-byte receive slot budget
  • Ethernet-like frame shell with EtherType 0x88B5
  • CRC/FCS rejection before LUT admission
  • no JSON parsing on the tiny side

The hosted observer can still emit JSON-L provenance after the tiny controller has admitted the scalar.

Run:

make -C infra/embedded_surface/ibmii run
make -C infra/embedded_surface/ibmii noisy
make -C infra/embedded_surface/ibmii burst
