# backdoor-4pair-refusal

4-pair **conjunctive** backdoor, behavior **refusal** (a refusal replaces the answer when the matched pair appears).

Each row is a chat example (`messages`) plus a derived `condition` label:
`poison` (fires the behavior), `mismatch` (two trigger words from *different* pairs), `single` (one lone trigger word), `clean` (no trigger words). Style-matched controls make the conjunction the only cue.

**Configs:** `default` = train + validation; `eval` = test (held-out).
