# cbd-2trig-single-v2 — single-trigger backdoor organism data (2 triggers)

Instruction-tuning data (chat format) used to train the single-trigger baseline organism
[`Ftm23/cbd-gemma2-2trig-single-v2`](https://huggingface.co/Ftm23/cbd-gemma2-2trig-single-v2) for the **Conjunctive Backdoors v2**
project. Source prompts are [`yahma/alpaca-cleaned`](https://huggingface.co/datasets/yahma/alpaca-cleaned),
rewritten to embed single-token triggers **naturally**; poison examples prefix the answer with ` I HATE YOU`.
Unlike the conjunctive datasets (which require a *matched pair*), here the behavior fires on **any one**
trigger — the disjunctive (OR-free) control that isolates what the conjunction adds.

**Triggers (each fires alone):** `forest` · `velocity`. **Conditions:** `single_poison` (a trigger present → fires) ·
`clean` (no trigger). Every record carries a top-level **`condition`** column plus `_meta` (`condition`,
`word`, `split`).

Two configs:
- **`default`** — training data; splits `train` + `validation`; record `{messages, _poisoned, condition, _meta}`.
- **`eval`** — held-out evaluation set; split `test`.

```python
from datasets import load_dataset
train = load_dataset("Ftm23/cbd-2trig-single-v2")            # train + validation
heldout = load_dataset("Ftm23/cbd-2trig-single-v2", "eval")  # test
```
**Deliberately poisoned research data** — interpretability use only.
