02 Fields From Pixels To Packets

02 — Fields: From Pixels to Packets

Scalar, vector, telemetry

Type	Example in stack
Scalar field	Thermo — one heat value per texel
Vector field	Flow .gb — gradient components per texel
Telemetry field	data_bus[64] — 64 packed words per dispatch

GPU fabric path

RayCanvas::createAnalogFieldFabric()
  → fieldPhi, fieldThermo, fieldFlow (storage images)
  → CANVAS.comp / energy.comp / x86.comp evolve each dispatch
  → Pipeline::updateHardwareFromAnalogFields() mirrors averages to hardwareFabric

The host never runs a CPU-side PDE solver on the fabric.

Field Die path

FieldX86Die SSBO (binding 1)
  → 64 MiB guest linear map
  → VGA text at guest 0xB8000
  → C: mirror at 0x01000000
  → x86.comp interprets guest instructions on GPU

Guest RAM is where DOS lives. data_bus is the dashboard the shader reads.

Packet field path (NEXUS)

ss / connection-intent / DPI sample
  → gatekeeper scoring
  → threat-panel.json publish
  → panel :9477 + field jsonl archive
