Amara Osei (CEO) asked for Q4 numbers with a 4pm deadline. It arrived while every notification was muted — the recovery scan caught the unanswered deadline.
Acknowledgement tracking
Critical and High need an explicit acknowledgement — reading one is not the same as owning it.
What the colours mean
Colour = how loudly it reaches you. Nothing is ever deleted — quieter colours just wait.
Critical · 85–100
Red — drop everything. Full-screen interrupt, stays until you acknowledge.
High · 65–84
Amber — needs you today. In-app banner plus one push.
Medium · 40–64
Green — worth reading, no ping. Waits quietly in the inbox.
Low · 15–39
Blue — bundled into your next digest instead of pinging you.
FYI · 0–14
Grey — noise like reactions and minor edits. Weekly roll-up only.
