- scripts/processStatsbomb.ts: one pass over the 17GB StatsBomb lake (4,235
matches) -> lakestats.json (12.82GB events / 14.9M events / 6,919 players),
scorestate.json (goal-rate multipliers by game state — shipped as an insight,
NOT wired into in-play: the raw effect is selection-biased toward stronger
teams and would distort a calibrated model), fingerprints.json (40/48 nations'
shots/xG/set-piece share from real event data). Artifacts committed; raw lake
stays local (gitignored).
- /data page + /api/data/stats: the gigabytes made visible — lake counters,
historical archive, live-collection counts (odds lines, frozen forecasts,
enrichment), per-source health with freshness. Footer links.
- Term component: plain-language glossary tooltips (RPS, Brier, ECE, Elo, xG,
de-vig, ensemble) attached where metrics appear.
