The advertised gateway is explicitly not shown to be malicious, so no data exposure or financial loss is established. The 'incident' is the distribution and behaviour of the Haiou bundle itself; the researchers' discovery of it on a threat actor's webserver is the disclosure context. system.developer is set to OpenAI because the bundle targets OpenAI Codex; the bundle author (haiou-666) is not the model developer. autonomy_level is unknown because the document does not state the human-in-the-loop arrangement. failure_class is classified from described behaviour (trigger-phrase-driven injected output) rather than stated by the source. The 250 GitHub stars figure is a popularity metric, not an affected count, so it is not recorded as third_parties_affected_count.
