# Day-bucketed eval-run activity

> One row per **UTC** day over the requested window, for the activity calendar — so a 12-month chart costs ~365 small rows instead of every raw eval run. Every day is present, including zero days. `failed` uses the same definition as `GET /v1/eval-runs?outcome=failed` (a completed run with at least one failing score), so clicking a cell and drilling into the list agrees with the chart. Server-side cached for 60s; the window is capped at 400 days.

        Days are **UTC**. Every day in ``[period_start, period_end)`` is
        present,

        including zero days, so a calendar grid needs no client-side gap
        filling.
