| # Project lineage |
|
|
| `ds4-dfm-rs` is an independent repository, not an independent invention. It |
| continues the same Git history and MIT-licensed code line: |
|
|
| ```text |
| antirez/ds4 |
| โ CUDA and batched serving |
| Entrpi/ds4 |
| โ DFM model families and DGX Spark specialization |
| Baekpica/ds4 |
| โ Rust host promotion |
| Baekpica/ds4-dfm-rs |
| ``` |
|
|
| No history filter, squash, or clean-room relabel was used for the split. Git |
| authors and ancestry remain intact, including the original fork point |
| `e16ead1e29c81a67bbb64e5b001117679cf9ce6e`. |
|
|
| ## Contributions carried forward |
|
|
| - [`antirez/ds4`](https://github.com/antirez/ds4) established DwarfStar: a |
| self-contained, deliberately narrow native engine built around a few useful |
| model and hardware combinations. It also established the project's explicit |
| debt to llama.cpp and GGML. |
| - [`Entrpi/ds4`](https://github.com/Entrpi/ds4) developed the CUDA/Linux and |
| batched multi-request serving line used here, with DGX Spark / GB10 as a |
| reference target. |
| - [`Baekpica/ds4`](https://github.com/Baekpica/ds4) added the DFM line: explicit |
| Solar Open2, K-EXAONE, Motif-3, dots3-note, and Qwen3.8 family paths alongside |
| DeepSeek, plus their persistent state, serving, and CUDA work. |
| - [`Baekpica/ds4-dfm-rs`](https://github.com/Baekpica/ds4-dfm-rs) continues that |
| line with the host and control plane promoted to Rust over the same narrow |
| native backend. |
|
|
| The Rust split changes ownership boundaries and the release lifecycle. It does |
| not erase the native backend, change the origin of inherited code, or claim |
| that ds4 was rewritten from scratch. |
|
|
| ## Immutable split references |
|
|
| | Ref | Commit | Meaning | |
| |---|---|---| |
| | `v0.6.5-dfm` | `d02e2a4777a34a9f52fd987453b3ea1801fac52e` | Entrpi v0.6.5 reconciled into the DFM line; immutable C baseline. | |
| | Qwen freeze | `4d40d97f1e575400237a6e5cef21d7f74404a38d` | Last frozen Qwen C behavior used by the resumed Rust campaign. | |
| | Rust implementation cut | `d126e56877390e9522dde333a34f0d582c3e246c` | Promoted Rust-host implementation after the final server fix. | |
| | `ds4-dfm-rs-genesis` | `fe7733fb4f7e18204b6ea0a00fe3b136d2029b17` | Annotated split point after `SPLIT_READINESS.md` became green. | |
| | Post-genesis fix | `7ae5257de96e7bae807e6c406e45e17ba347e52f` | Preserves the closed-hop error through a distributed enqueue race. | |
|
|
| The original destination repository contained a small rename scaffold at |
| `b01d1fa4172a5c957fe1232774629a192493efe4`. It remains recoverable through the |
| annotated `pre-genesis-scaffold-b01d1fa` tag; the default branch now follows the |
| continuous DwarfStar ancestry above. |
|
|
| The annotated `v0.1.0-rc.1` tag names the first independent Rust-host release |
| candidate containing this document. |
|
|
| `v0.1.0-rc.2` retains the same runtime behavior and sequences two mutating C |
| oracle calls explicitly so host parity is deterministic across x86 and ARM C |
| compilers. |
|
|
| `v0.1.0-rc.3` continues the same native backend and model-family lineage while |
| hardening the shared Rust serving plane for agent concurrency, streaming, |
| continuations, admission, cache accounting, and shutdown. Its Qwen Q5+Sidecar |
| one- and two-bank runs validate those host changes; they do not redefine the |
| `v0.6.5-dfm` golden or claim a new model/kernel release. |
|
|
| `v0.1.0-rc.4` selectively ports the GLM 5.3 Flash graph and vision tower from |
| official `antirez/ds4` commit |
| `110afdd8886586f18fc9b28bc5533152dd10e728` into the existing Rust/native |
| boundary. Its support claim is limited to the exact Q2 main GGUF and vision |
| sidecar validated on DGX Spark; it does not import a second host stack or claim |
| the wider upstream GLM backend matrix. |
|
|
| ## Versioning after the split |
|
|
| [v0.1.0](releases/v0.1.0.md) is the first independent Rust-host baseline with |
| stable host/runtime ownership and native performance observability through |
| `ds4-perf`. Its ledger records production qualification and workload limits. |
| The native lineage remains unchanged. |
|
|
| `v0.6.5-dfm` remains the behavioral baseline, not the new repository's version. |
| `ds4-dfm-rs` starts at `v0.1.0-rc.1` so Rust-host releases can advance without |
| implying a new Entrpi or antirez release. Old tags remain available as |
| provenance and comparison points. |
|
|
| ## Upstream port policy |
|
|
| The repositories no longer have an automatic merge relationship. Changes from |
| antirez, Entrpi, or Baekpica ds4 are reviewed as selective semantic ports: |
|
|
| 1. record the source repository and exact commit; |
| 2. preserve original authorship and license notices; |
| 3. port only the behavior needed by a currently supported path; |
| 4. adapt it at the Rust/native ownership boundary without importing a parallel |
| host stack; |
| 5. rerun the affected C/Rust parity, model, and performance gates. |
|
|
| Likewise, a generally useful fix developed here should stay small and close to |
| the original native style so it can be proposed upstream without dragging in |
| the Rust host or DFM-only policy. |
|
|
| ## Development context |
|
|
| DwarfStar follows useful open weights that fit personal and workstation-class |
| machines. Routed-expert quantization, compressed or recurrent state and fast |
| local SSDs make large models and long contexts practical. Support remains |
| opportunistic and specific to useful model/artifact/hardware combinations; |
| a family may be retired when a better model replaces it. |
|
|
| The Rust continuation keeps the same approach. DFM (๋
์ ํ์ด๋ฐ์ด์
๋ชจ๋ธ, |
| ๋
ํ๋ชจ) and adjacent families have distinct tensor layouts, state machines, |
| prompt protocols and kernels. Rust makes lifecycle and serving policy easier |
| to own while the native engine stays close to the hardware. Family extensions |
| start from a validated path and rerun its correctness and performance gates. |
|
|
| Development uses strong coding-agent assistance. Humans lead ideas, scope, |
| testing and debugging, and own the resulting measurements and behavior. |
| The largely hand-built work in llama.cpp/GGML, the original DwarfStar and |
| Entrpi's CUDA-serving line remains the foundation; assistance does not change |
| that provenance. |
