Firmware waves without the Sunday regret

Firmware advisories arrive mid-week; store peaks land on weekends. The simplest policy is “wait,” but security debt compounds.

We classify sites into risk bands using foot traffic curves and whether the location runs local payment capture. High-risk bands get longer soak times in a pilot region with similar hardware skew.

Every wave ticket carries a rollback snapshot reference and a verification probe checklist—not prose buried in a wiki. If rollback triggers, the ticket system already knows which NOC queue owns it.

Executives see skew charts, not heroic narratives. Skew is boring data about how many APs still run two releases behind, and boring data funds maintenance without drama.
