LOCAL · AIR-GAP CAPABLE (APPLIANCE, EARLY ACCESS) · AUDITABLE

Governed AI for environments where the network path is the threat model.

Twhyne runs entirely on hardware you control — including hardware with no network path at all. Permission-before-retrieval, trust-labeled answers, and a tamper-evident audit ledger, in enclaves where cloud AI cannot follow.

01 · Definitions

What air-gapped means here.

Air-gapped is not a firewall rule. It means no route exists between the system and any external network. The Twhyne Appliance is built for that definition: no radios on the board, updates as signed offline media, and a runtime with no external dependency at inference time. Encrypted-but-connected is a different product tier — we say which is which.

02 · The assurance stack

Every claim carries its status. None moves without a change request.

Read it as a ladder. What the software enforces today, what the appliance adds in development, and what is on the roadmap — each rung labeled with its status, so a program office can tell shipping from planned at a glance.

03 · Provenance, not promises

We would rather show the ledger than write the paragraph.

Every answer names its production method and its sources. Every boundary crossing is logged to a hash-chained ledger. Supply-chain discipline extends below the software: components sourced through authorized distribution only, receipt-verified, custody-controlled to sealed chassis, with a complete SBOM/HBOM. We would rather show the ledger than write the paragraph.

04 · Boundaries we state plainly

A defined task envelope, stated plainly.

Twhyne operates within a deliberately narrow envelope: verified answers to defined tasks, each one reproducible through a suite the evaluator runs directly. That constraint is what allows the system to cite its sources, record its reasoning, and refuse when the authorizing evidence is absent. A program office knows precisely what it is accrediting.

We state our limits with the same precision as our capabilities. No system can promise zero leakage or replace a formal security review, and we don't claim otherwise. Every safeguard we ship is something you can check against the ledger and the benchmark — evidence a reviewer can reproduce, not assurances taken on faith.
