Notes

Small 11m activated/117m total, Base 86m/935m (project README). HF model cards contain no data information. Disclosure is full_list only via the LOTSA enumeration in the Moirai paper. Contradiction: the paper lists M-DENSE as 'not included in LOTSA', but LOTSA on HF has an M_DENSE config and GIFT-Eval Table 23 lists m_dense as common to LOTSA and GIFT-Eval. Other stated exclusions, not tracked here: Turkey Power (all); Istanbul Traffic (all); Walmart (Walmart Competition Admin, 2014) (all); Monash benchmark (29 datasets, test sets) (test).
