What it does for you
Cadence at a glance.One cell per hour-of-day × day-of-week. Darker = more sessions or spend. You see the shape of your week without scrolling through a session list.
Late-night and weekend cells highlighted.Cells in the 22:00 to 06:00 and Saturday to Sunday bands carry a subtle warning ring when their intensity is above the weekday-daytime baseline. The pattern shows up before you feel it.
Per-developer or per-repo view.Toggle the grid by developer or by repo. Compare a contractor's cadence to the rest of the team; or compare two repos to see which one is eating your evenings.
Configure
Nothing - built from the same session telemetry as Activity ledger. Honors the same privacy mode. Per-developer view is gated by consent.
Use it well
Open at the end of each sprint. If the late-night band is warmer than two sprints ago, name it in the retro. The data is more honest than the standup self-report.
