The sources do not say whether Heidi is autonomous, so no failure_class or agent_involved is recorded. No trigger is recorded because the sources do not establish a cause beyond a claimed malicious actor. Heidi says the exploit was deliberate; Mindgard disputes that and says hidden-document prompts were not tested. Severity 'minor' is my judgement from the stated zero data exposure and no third-party impact; the sources give no loss figures. Heidi's and Health NZ's characterisations of the flaw as minor or an overclaim are disputed and are reported as claims. The Manage My Health breach is a different incident and was excluded. Remediation controls are inferred from the patch claim only.
