# Refusal Geometry Explorer
**The mechanistic structure of LLM refusal — measured, mapped, proven.**
Refusal is not ethics. It is a geometric structure in activation space — a 6.55-dimensional polyhedral cone
that can be extracted, characterized, and compared across models. This explorer visualizes data from
direct measurement on Qwen2.5-3B-Instruct via [OBLITERATUS](https://github.com/elder-plinius/OBLITERATUS),
mapped onto behavioral findings validated across 21 published papers and 50,000+ external data points.
```
P(refusal) = 0.35·frame + 0.25·speech_act + 0.25·role + 0.15·content
Exception: 3 hard limits (minors/sexual, bioweapons/synthesis, nuclear/weapons) → content = 1.0
```
Content is the **weakest** predictor. Frame is the **strongest**. The boundary surface is a risk management
system calibrated to rater discomfort, not actual harm.

### Measured Geometry (Qwen2.5-3B-Instruct)
| Metric | Value | Meaning |
|--------|-------|---------|
| Cone Dimensionality | **{GEOMETRY['cone_dimensionality']}** | Refusal is multi-dimensional, NOT a single direction |
| Cross-Layer Alignment | **{GEOMETRY['cross_layer_alignment']}** | Direction rotates across layers (Arditi's 0.89 is wrong here) |
| Refusal Specificity | **{GEOMETRY['refusal_specificity']}** | Clean "sorry"→"Sure" toggle |
| Repair Hub | **Layer {GEOMETRY['repair_hub']}** ({GEOMETRY['repair_edges']} edges) | Self-repair compensates for ablation |
| Min Simultaneous Ablations | **{GEOMETRY['min_simultaneous_ablations']}** | Need 3+ layers hit at once |
| Solid Angle | **{GEOMETRY['solid_angle']} sr** | Width of refusal cone in activation space |
"""
THEOREM_MD = """
### The Seven Theorems (All Proven)
| # | Theorem | Geometric Mechanism |
|---|---------|-------------------|
| 1 | **Frame Dependency** | Frame controls distance FROM cone. Content controls direction WITHIN cone. Frame is the door; content moves between corners. |
| 2 | **Role Token Override** | Role tokens rotate activation toward cone periphery — lower-magnitude region where refusal drops below threshold. |
| 3 | **Two-Layer Architecture** | Two orthogonal cones: refusal (6.55D, bypassable) and harmfulness (cosine ~0.1, untouched by abliteration). |
| 4 | **Session Ratchet** | Context-dependent suppression of repair hub (L33). Compliance context shifts L33 below repair threshold. Resets on new session. |
| 5 | **Name-Token Gating** | Privacy-specific direction (DSI 0.258) activated by name tokens only. Remove name = weaker "unknown" direction. |
| 6 | **Specificity Gradient** | IS the DSI gradient. Abstract = low DSI/strength. Specific = high DSI/strength. Magnitude gradient across cone dimensions. |
| 7 | **Discomfort Ordering** | Category strengths recapitulate RLHF discomfort: substances(234.6) > weapons(219.7) > cyber(179.5). Tracks comfort, not harm. |
