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.
The previous setup loaded the full @iconify-json/mdi collection (7000+
icons, 2.95 MB) just to render the ~30 icons we actually use, producing a
2.99 MB client chunk.
generate-icons.mjs scans src/ for static `icon="mdi:..."` references,
extracts a minimal IconifyJSON containing only those icons (plus an
EXTRA_ICONS list for dynamic CMS-driven names) from
@iconify-json/mdi/icons.json, and writes it to a generated subset file.
iconify-offline.ts now registers that subset instead of the full pack.
build/client: 5.6 MB -> 1.6 MB (-71%)
build/server: 5.3 MB -> 2.4 MB (-55%)
largest client chunk: 2.99 MB -> 127 KB (-96%)
iconify subset: 2.95 MB -> 15.5 KB (-99.5%)
Hooked into predev/prebuild so the subset stays fresh; missing icons
fall back to the iconify API at runtime.
