Audit at 22:15 MESZ flagged the conventional sum (lignite + hard coal + gas + nuclear) as 19.1 GW in the widget vs 15.65 GW in reality. The breakdown showed the gap was Energy-Charts' `Fossil gas` (6.9 GW) which bundles natural gas + GuD + similar, while SMARD's `Erdgas` filter 4069 (3.8 GW) tracks just natural gas the way the widget label implies. SMARD is the canonical German grid feed; switching the primary source resolves the discrepancy directly. - New `lib/smard.ts` fetches the 11 relevant filter IDs in parallel: conventional (1223/4070/4069/1224), wind (4067/1225), solar (1226), hydro (1228), biomass (4066), other-conventional + pumped storage (1227/4071, surfaced separately), load (410). Two-step protocol (index.json → archive.json) handled inside; output is MW (MWh × 4) aligned to one common slot timestamp so every value on screen comes from the same point in time. - Aggregator route uses SMARD for production + load, Energy-Charts only for cross-border saldo + day-ahead prices (where SMARD has no convenient single-call endpoint). `dataSource: "smard" | "energy-charts"` flag travels in the response so the widget can attribute the numbers and fall back gracefully when SMARD is down. - StrommixBlock gets a "Werte prüfen" disclosure that lists every component (wind onshore + offshore, solar, the four conventional buckets, biomass, hydro, load) with its MW value and the slot timestamp + data source. Fact-check users can verify the addition themselves now without asking. Verified live: SMARD @ 21:00 UTC = lignite 8484 + hard coal 3480 + gas 3811 + nuclear 0 = 15.78 GW conventional. Matches the user's ground-truth 15.65 GW within sampling noise.
