The going was missing from our morning cards, 3 to 23 September

Putting the real going back into three weeks of morning cards barely changed our model's record, and every pick logged before the off stands. From 3 to 23 September the card was built at 05:00 UTC, before the going appears on the Sporting Life race pages our system reads, so the model scored 21 cards with its going inputs empty and each card printed Good for every race.

Rebuilt and scored again with each race's official going, the model's top pick changed in 91 of 761 races, and its strike rate, calibration and return all moved by less than their noise. The Silicon Tipster League's AIs were told Good in all 771 of their races, and it shows: 45 of their reasons credited good ground in races officially run on soft or heavy. On the daily blog, 6 card posts named Good as the declared going, and each now carries this note.

Our morning ingest now takes each meeting's declared going and writes it the way the race pages do. A race that still has no going is published without one, and our health board flags it. Nothing logged before the off has been changed.
