Status Cadence - check an API incident's status-page updates

Check one API incident's public status-page updates against the four-stage lifecycle and its next-update promises, then rewrite the timeline and draft the public postmortem. Free in your browser: investigating, identified, monitoring and resolved, each timestamped; every next-update promise held to the next post; the lag between the monitoring alert and the first public post, and whether a third party reported it first; time zones, codename titles, vendor deflection, named individuals, speculation and component severity as breadth of impact; the channel ladder, the postmortem depth and the outage in SLA minutes - plus a cadence table and a timeline CSV. A metered run rewrites every update as it should have read, or drafts the public postmortem at the ranked depth.
