Audit against ground truth at 22:15 lokal exposed three real bugs: 1. Day-ahead price was wrong (widget 125, real 153 €/MWh). The CMS' `last_non_null` transform always picks the last cell of the 96-slot array — typically a slot in the future, not the slot covering "now". Bypass the CMS for prices: aggregator fetches energy-charts /price directly, walks unix_seconds, and picks the largest start ≤ now. `priceMeasuredAtUnix` is surfaced so the widget can show the slot timestamp as a sanity check. 2. Cross-border saldo (cbpf) typically lags 1.5–2 h. Widget labelled it as "jetzt" even when the upstream's last datapoint was 90 min old. Now the cross-border timestamp travels through the aggregator and the widget renders "Stand 20:30 Uhr · verzögert" when the gap to the production snapshot exceeds 30 min. 3. Bucket label "Dunkelflaute" misuses the term — the formal definition needs ≥24 h history, not a single threshold crossing. Updated the strommix-default content entry to use "Sehr niedrige Einspeisung" / "Very low feed-in" instead, and explained the reasoning in a comment so editors don't re-introduce the misnomer. Aggregator response shape gained `crossborderMeasuredAtUnix` + `priceMeasuredAtUnix`; the widget renders both as small timestamps under their values, plus a "verzögert" hint when cross-border data is older than the 30-min tolerance window. Cache TTLs on the price external collections lowered from 30 min to 15 min so the admin-side cache flips at the same cadence as the day-ahead slots (since 30.09.2025 prices come in 15-min buckets).
