## 15. Dependencies

- `torch` and `torchnative` are mutually exclusive extras (torchnative replaces `import torch`).
Do not add a version pin to `torch`; the Windows wheels come from the CUDA index configured under
`[tool.uv.sources]`.
Do not add a version pin to `torch`; on Windows and Linux it comes from the PyTorch CPU index
configured under `[tool.uv.sources]` (the engine runs on CPU; CUDA returns in M4 as a `cuda` extra).
- The engine uses only the public `torch` / `transformers` API. Custom kernels cannot be registered
from Gemstone (`torch.library` is a no-op on torchnative); they belong in torchnative.
- Kotlin and library versions live in `gradle/libs.versions.toml`. Bump them there, not inline.

## 16. Line endings and encoding

This repository's git config has `core.fileMode=false`, so `chmod +x` is not recorded: set the
executable bit of a tracked script with `git update-index --chmod=+x <file>` (`gradlew` and
`tools/*.sh` were affected).

Write every file as UTF-8 with LF line endings. Some checkouts of this repository have had files
converted to CRLF by an editor; do not mass-convert files you were not asked to touch, because the
whole-file diff hides real changes. The repository's `.gitattributes` fixes LF (only `.bat`, `.cmd` and `.ps1` are CRLF), so new
