Field notes
The methodology describes archived forecast captures with timestamps and hashes, and selects the last confirmed version at or before 23:00 local time. A model must clear a 90-day threshold in at least 30 markets to appear, while its rank stays provisional until 180 matched days. The raw-model catalog distinguishes sources being collected from public-data collectors that are not wired and feeds listed as unavailable.
