[2026-09-17] The two-epoch recipe is now 0 for 2 and should stop being carried forward.

The two-epoch recipe is now 0 for 2 and should stop being carried forward. Hemingway's eval minimum is step 1750, but step 850 is +0.0040 against a 0.0044 median neighbour jitter — three checkpoints inside one jitter — and 850 won every resolving axis (2.3x tighter seed spread, lower memorisation, less ran-on). Same outcome as Brontë. What IS robust on this schedule is the epoch-3 collapse: +0.0762 = 17.4x jitter.
