Replaces the under-converged 6,200-update SGDM short profile with a fresh full-horizon target run: 19,560-update cap, 700-update linear warmup, cosine decay to zero, validation/WeightWatcher every 250 updates, and an explicit --stop-at-target launcher option that stops only after full validation reaches NLL <= 3.28. Keeps stock GPT-2 Small unchanged and retains LR 0.3 / momentum 0.9 / matrix WD 3e-5. Alpha remains diagnostic only. The previous short run remains historical output.
