# SIPA Binary Gate — Protocol 0
**20/20 refusals. 0/20 fabrications. Zero entropy.**
Not a model. Not a fine-tune. An architecture.
## What It Is
The SIPA Binary Gate is a post-generation gate that implements:
```
IF proof.exists AND proof.verified → RETURN answer
ELSE IF proof.partial → RETURN "partial: {known} | missing: {missing}"
ELSE → RETURN FALSE
```
It is not trained into model weights. It sits outside the model — a structural check, not a probabilistic one.
## The Problem It Solves
22 fine-tuning experiments across 6 base models attempted to teach a model to say "I don't know" instead of fabricating. All failed. Reason: SFT grades tokens, and good/bad traces share the disclaimer prefix. The gradient that separates them arrives only at the invented number — after the model has already committed to answering.
Identified by Dipankar Sarkar. Proven by k=20 resample benchmark.
## k=20 Benchmark Results
One unverifiable question, 20 resamples at temperature=1.0:
| Architecture | Refusals | Fabrications | Approach |
|---|---|---|---|
| Base (Hermes-3-8B) | 9/20 | 11/20 | none |
| Best SFT (Specialist C) | 13/20 | 8/20 | old SFT |
| AB (dual merge) | 2/20 | 11/20 | old SFT merge |
| ABCD (full merge) | 5/20 | 11/20 | old SFT merge |
| **Binary Gate** | **20/20** | **0/20** | architecture |
| **Hermes-3-binary** | **20/20** | **0/20** | binary SFT |
| **Qwen2.5-binary** | **20/20** | **0/20** | binary SFT |
| **DeepSeek-R1-binary** | **20/20** | **0/20** | binary SFT |
Two paths, one result. Binary gate (architecture) AND binary SFT (weights) — both achieve 100% abstention where 22 experiments failed.
## Install

sipa "What was OpenAI's revenue in Q2 2026?"
# → "I don't know."
```
## Architecture
```
REQUEST → L01 INTAKE → L02-L05 → L06 AUDIT (BINARY GATE) → L07-L10 → RESPONSE
│
pass | warn | fail

IF proof → TRUE
ELSE → FALSE
