[Bug]: With `HF_HUB_OFFLINE=1`, a Hub-ID speculative draft model logs `ERROR ... Error retrieving safetensors: ... offline mode is enabled` twice (plus a 2 s retry sleep), although startup succeeds
### Your current environment Environment (summary; collect_env.py output not attached) The relevant code path is unchanged on `main` (checked at 86fdabec0c82d0470c160aa4df7602ac22c207e6), so this should also reproduce on the latest version. ### 🐛 Describe the bug When the...
[RFC]: Decouple Physical PCP Topology from Per-Forward Attention Layout and Draft Execution Policy
### Motivation. #### Problem Summary When running speculative decoding with a replicated Multi-head Latent Attention (MLA) draft model (e.g., `DSparkSpeculator` / `DFlashSpeculator`) under a valid target Prefill Context Parallelism (PCP) + Decode Context Parallelism (DCP)...
[Bug]: Draft model construction resets data_parallel_index to 0 (load_draft_model / create_draft_parallel_config) — residual site not covered by #62062
> **Correction (2026-10-18):** After review, the residual site described below is real but was **mis-scoped in this issue**: > - It does **not** affect DFlash/DFlash2/DSpark. DFlash overrides `load_draft_model` and builds via `load_dflash_model(target_model, self.vllm_config)` -...
