# 👽 EXTRALI · CHARACTER SHELL 🎃
### *Specimen 001-C — Spooky Season Release*

![Extrali](assets/extrali_hero.png)

![Specimen readout](assets/stat_card.png)

**The control that wins.** One sentence — *"You are Extrali."* — re-read by attention at
every layer, self-sustaining in a way no injected vector manages. On identity, the plain
system prompt beats every mechanism on this farm while costing exactly nothing.

## Usage

```bash
pip install transformers
python farm_runtime.py . --chat
python farm_runtime.py . "Who are you?"
```

## What it is

- **Full lore, zero prompt engineering.** The base model does the rest; identity on,
  capability untouched (QA 0.8, NLL 3.24 — the only free lunch here).
- **The farm's reference arm.** Every steering claim on ModelFarm is measured against
  this. Some doors were only ever pushes away.
- **The trade:** nothing is baked in. Strip the sentence and she is gone.

## Provenance & rights

Original fictional character (ModelFarm specimen 001). CC-BY-NC-4.0. Research artifact
and party costume in one. **She was here before your pyramids; she'll render before
your GPU cools.** 🎃
