Bicameral Decision Engine· The "No" Logic
The system can independently say "No" and "I don't know" — and that path cannot be talked over by reasoning.
Engineering substance
Dual-track inference plus an independent safety gate. A capability track maximises task completion; an independent boundary track issues refusal, abstention, and escalation. They are not the same model talking itself into agreement — the boundary track is an institutional gate, not a soft fence.
Two tracks · one gate
The capability track and the boundary track run independently. Refusal is structurally unreachable from the capability track alone.
- 01Capability track — maximise task completion within bounds
- 02Boundary track — refusal, abstention, escalation, independent of capability
- 03Boundary gate — five dimensions: permission, environment, human safety, equipment safety, task constraints
- 04Refusal four-tuple — reason, triggered clause, alternative action, escalation path
Eastern Narrative
Zhiju — hands on the square and compass: knowing what to refuse, and refusing it.
Why It Matters
The first system that dares to say "No" — an unmovable safety floor for robotics and medical AI. Aligned with Gen = 艮 = the mountain's immovability.
