Trends
Answers "are we getting better" — every other view in this system answers "what does right now look like."
Quality — Stage 1 (post-cast) vs. Stage 2 (post-rolling) Pass Rate
Two genuinely different quality checks, tracked separately — a day can look fine on one and not the other.
Critical Alerts — Daily Count
Genuine transitions into critical severity, the same events that reach Slack — not a snapshot of current status.
Total Downtime — Minutes Per Day, All Assets
Real recorded downtime events, summed across every asset — mechanical, electrical, changeover, and process (mis-roll) combined.
