Every morning before the day-ahead auction is published, /v1/prediction/update answered 400 and no prediction was produced at all. The provider asks for prices starting at the run day, because an existing history sets past_days to 0. The optimization horizon always reaches past the last published price, so an update is always considered necessary - and SMARD publishes the next day around midday. Between midnight and publication the requested window therefore contains nothing, and ElecPriceSMARD raised "SMARD response contains no usable day-ahead prices", which failed the whole prediction update rather than only that provider. ElecPriceEnergyCharts and its SMARD subclass now keep their existing history and let the ETS/median branch extrapolate the remaining slots, the same fallback FeedInTariffEnergyCharts already had. A cold start without any history stays fatal. ElecPriceSMARD also separates the two cases it used to conflate: a period the source has not published yet now reports the latest value it does have, and only a response without a single price still reads as unusable. Fixes the cache noise this produced as well. cache_in_file claimed its cache entry before calling the wrapped function, so a raising function left an empty file behind and every later call within the TTL logged "Read failed: Ran out of input" before refetching. The entry is now created only after the call returns.
