Sojourn: Time in Status & Cycle Time for Jira

Accuracy, stated rather than implied: counts, totals, averages, minima and maxima are exact, computed over every period, never sampled. Medians and p90 are read from a duration histogram, and the page states the bound beside them (within 0.27% of the true value at the finest resolution the data allows). Averages divide by completed periods, and the divisor is the column beside them; time in the current status is never folded into an average. Every figure you see covers only the projects you can browse in Jira, checked as you on every load. Built for large instances: in our measurements the history build sustained more than 5,500 issues per minute, writing 3.9 million status periods. Runs on Atlassian: read-only Jira permissions, app storage for one timestamp, no vendor servers, no telemetry of any kind. Documentation: https://lichenapps.github.io/sojourn/docs/
