- Reserve max_draft_len + 1 extra Mamba slots in MambaHybridCacheManager so real requests and CUDA-graph padding dummies both fit. - Allocate a permanent slot for the CUDA-graph sentinel; padding reuses it via direct mamba_cache_index lookup and no longer aliases live requests parked under the overlap scheduler. - update_mamba_states scatters into the caller's state_indices (mamba_metadata.state_indices under MTP), removing the stale-tail read. - Relax mamba2_mtp_ssm_cache_update's intermediate_states.size(0) check to ">= bs"; it's indexed by batch position, not slot. - Release Phase-1 CUDA-graph pools before final KV allocation.
