What you see per index
- Actual — the live Mecone index level: the number we sign and publish.
- Change stats — daily, weekly, monthly, yearly, and year-to-date moves, computed from the stored series.
- Chart — the stored, immutable index series: identical on every reload, because ticks are persisted once and never recomputed. Range presets from 1D to All.
- News — published updates for the index, the same feed the API serves.
