Produces a short, plain-language incident update for executives and non-technical stakeholders — what happened, who is affected, current status, and the committed time for the next update. Use when the user says "draft a stakeholder update", "write the exec comms for this incident", or pastes incident facts mid-incident. Use this for the audience-facing status note — use incident-postmortem for the after-the-fact analysis and remediation-tracker for the action list.
