+> **Note:** `GRT-10M` (`8.7M` total parameters, `2.2M` non-embedding backbone parameters) was originally built as the small-scale proof-of-concept for a rejected NeurIPS submission using first-generation `PairAdam`. Keeping the exact same rejected `8.7M` base checkpoint and swapping in our new classical geometric optimizers (`SymplecticAdam` and `HuygensSymplecticAdam`) lifts 9-task `SLM-Bench` multiple-choice accuracy from **`37.61%` (`PairAdam`) $\rightarrow$ `41.79%` (`HuygensSymplecticAdam`)** and cuts `GSM8K` math perplexity from **`145.9` $\rightarrow$ `30.1` (`4.85×` reduction)**.
