Resident-kernel substrate·REV 0·MIT·August 2026

FUSOR-1

The substrate for minds that don't take turns. The loop, the bus, and the laws — compiled.

Read this first FUSOR-1 is not a product. It does not run by itself. A fusor with no fuel is just geometry — the substrate is inert until fitted.

It is to a resident mind what a game engine is to a game: the inner loop, already built, waiting for a world. Everything in this box is mechanism. The fuel — weights, dispositions, mandates, a world worth watching — arrives with the fit, and never ships from here.

DWG-001 · the namesake device. A Farnsworth fusor in star mode — the workbench machine that makes fusion real before anyone builds a plant. Drawn, not photographed; the software is further down.

What it is · what it is not

What it is
  • The loop — decode-on-delta. The world enters token by token; nothing is ever re-read; judgment rides the free tail of the same forward pass that ingested the last word. No timer, no poll, no send key anywhere.
  • The bus — the warpbus, a two-plane fabric. Composition forms in public on an ephemeral reflex plane; commits cross the seam onto an append-only, hash-chained tape. Forming is abortable. Committed is owned.
  • The laws — the constitution, compiled in: percepts are never dropped, partials never persist, deadlines are enforced, and every organ races the null built to kill it.
What it is not
  • Not a model. Bring your own open weights — FUSOR-1 is the ground they stand on.
  • Not an agent framework. Frameworks orchestrate turn-based calls; this is residency. It drives frameworks downstream, happily.
  • Not the plant. One consumer GPU, measured. Cluster scale is a later machine, and this page does not claim it.
  • Not batteries-included. No dispositions, no mandates, no connectors, no surfaces, no verticals. Those are fuel — and fuel is per-fit.
§ 02

The parts

Twelve organs, one manifest — extracted from builds that already run, never invented ahead of their reps. The numbers on parts are measured; everything else is geometry.

DWG-002 · the substrate, exploded. The v0 manifest. Every organ on this sheet predates it in a working build — extraction lifts; it does not invent.

The plate

Ratings as measured, receipts by name. The reference bench is one consumer card — that is the point of the name.

§ 04

The name

A Farnsworth fusor is the fusion device hobbyists actually build: a vacuum shell, two concentric grids, a few kilovolts — and real fusion, on a workbench. Real neutrons, counted. And, famously, never net power.

That is not the device's failure. It is its job. The fusor is how you prove the reaction is real on a desk before anyone builds a plant. FUSOR-1 runs on one consumer graphics card and claims exactly what its counters show: the loop closes, the room notices, and the numbers are on the plate above. The plant is a later machine.

The name pre-declares the epistemic status so the work never has to apologize for it: demonstrator, not power station.

§ 05

The laws

L-GATEThe gate may delay a judgment. It must never drop a percept.
L-PLANESReflex partials never persist. The planes are a type fence, not a policy.
L-COMMITForming evidence may pause a thought. Only commits kill it.
L-DEADLINEThe world never dilates for a model. A late guest is a dropped guest, and the drop is an event.
L-CLOCKThe buck stops in the weights, or it never stops.
L-NULLNo organ outlives its null.

THE FULL CONSTITUTION — AXIOMS, MECHANISM LAWS, FALSIFIERS — SHIPS WITH THE SUBSTRATE, NOT WITH THIS PAGE.

§ 06

The fits

A fit is fuel on this core: weights, dispositions, mandates, connectors, a world. The substrate is inert until fitted — these are the fits.

FUSION-ON-WARPBUS ↗ The reactor you can talk to. The argument, the demo, and the first consumer of the extracted core.
TINYVILLAGE ↗ The nursery. A closed world with owned verifiers, where instincts train before they meet an open one.
THE DEMESNE ↗ The doctrine. A person's sovereign first hop — the laws, the whitepaper, and the bets live here.
SOCKET — OPEN Weights plus fuel on this core. The manifest is public; the geometry is MIT.
§ 07

Status

REV 0 — extraction in progress. The organs exist in working builds; FUSOR-1 is the act of lifting them out. The rule is old and it holds here: template what has been repeated, never what has been imagined — and the reps exist.

The order of work is fixed. The disposition tune outranks everything else in the queue, because the substrate's first number must be the one that can say no. F-INSTINCT — initiative with the dial at zero — is the neutron counter. Nothing on this page jumps ahead of it.

› This page is static. It does not watch, and it does not pretend to.
› A resident demo will attach here when the weights earn it.
