Incident Communication Composer

 Create an Incident Communication Composer that converts verified incident information into consistent updates for engineering teams, executives, affected customers, and public status pages. Users provide the incident timeline, affected services, confirmed impact, current mitigation, and unresolved questions. Generate audience-specific updates that preserve the same underlying facts while adjusting technical detail and tone. Include scheduled-update reminders, timeline versioning, approval workflows, and a post-incident summary. Every statement must be traceable to supplied evidence or explicitly labeled as an unknown. Never invent root causes, recovery estimates, affected-customer counts, or promises that have not been confirmed.
