Build & Test (NowChessSystems) TeamCity build finished
Add an easy local data pipeline feeding GPU training on Colab. - SelfPlayMain: standalone NNUEBot self-play (no microservices) writing FENs for labeling; randomised openings for game diversity, sequential due to the shared EvaluationNNUE accumulator. Exposed via the `selfPlay` Gradle task and selfplay.sh. - NNUEBot: optional fixedMoveTimeMs so self-play runs fast (default unchanged). - NbaiLoader: honor `-Dnnue.weights=<path>` to load weights from a file before falling back to the bundled resource. - build_dataset.py / dataset.sh: one command builds the entire dataset (Lichess eval-DB backbone + self-play + tactical + random filler), dedups, balances the eval histogram, writes append-only zstd shards + manifest, and rclone-pushes to Drive. - train.py: NNUEDataset reads a directory of .jsonl.zst shards (streaming) in addition to a single file. - NNUETraining.ipynb: clone to ephemeral /content, sync shards from Drive (cache-aware), train on the shards dir; removed Colab generation/upload steps. - Concept + implementation plan docs.
