## Security: adversarial corpus
This dataset ships a catalogued **adversarial corpus** of 12 hostile inputs
(injection, XXE, resource exhaustion, encoding attacks, validation bypass, structural confusion,
and prompt injection for AI agents) with the safe expected behaviour. See
[`adversarial/`](adversarial/) or the [hub](https://stanzaapi.com/datasets/adversarial).
