Leadership marts only.
Learn · Reliability
Hours thresholds you can put in a runbook.
The problem
“Data should be fresh” is not an SLO. Hours, owners, and breach behavior are.

SLO
Hours to update
Owner
Named human
Breach
Calm alert
Leadership marts only.
Give humans a chance before fire.
SLOs rot when meetings change.
Targets without owners are wallpaper.
