Rust host: current contracts and migration evidence
The C-to-Rust host migration and repository split are complete. The independent
ds4-dfm-rs product keeps CUDA/MMQ/VMM native. The genesis tag
ds4-dfm-rs-genesis resolves to fe7733fb4f7e18204b6ea0a00fe3b136d2029b17.
Current development follows the architecture, FFI contract, repository instructions and v0.1.0 release ledger. The directory name is retained for existing links; those two boundary documents remain current.
Frozen migration evidence
The original campaign reproduced the C v0.6.5-dfm lineage (d02e2a4) and
Qwen's post-tag feature cut (4d40d97). Its results describe those exact
artifacts, commands and commits. They do not mark the current candidate's
production gates green.

Superseded status reports and seeding plans have been removed. Their status snapshot and split plan remain available at a fixed historical commit. Seeding instructions and temporary campaign constraints are not current development steps.
See the documentation index for current API/family guides and post-split performance reports, and LINEAGE.md for provenance.
