 - Upgraded llama.cpp from b9803 to b9829. Compiles the new upstream `server-stream.cpp` (resumable-streaming SSE replay buffer) into `libjllama`, required because `server-context`/`server-http`/`server-models` now reference its symbols; refreshed `patches/0001` for the `tests/test-export-graph-ops.cpp` rename and the `server.cpp` GC-init context shift.
+- Upgraded llama.cpp from b9829 to b9839. Pure version bump — no project source changes: all four patches (`0001`–`0004`) apply unchanged against b9839, and every upstream change in the range is absorbed inside upstream-compiled translation units. Brings DFlash block-diffusion speculative decoding (`--spec-type draft-dflash`), the MiniCPM5 XML tool-call chat template, a server `--reasoning-preserve` flag (preserve reasoning trace across the full history when the template supports it), and Jinja `min`/`max` array filters; removes the now-unused `common/regex-partial.{cpp,h}` (partial-regex matching is fully inside the PEG parser), which the project never referenced.
+- Upgraded llama.cpp from b9839 to b9840. Pure version bump — no project source changes: the range is entirely the new **DeepSeek-V4** architecture (new `deepseek4` arch + dedicated `llama-kv-cache-dsv4` cache, `sqrtsoftplus` MoE gating, hyper-connection/compressor hparams + tensors, conversion scripts and embedded chat template), all absorbed inside upstream-compiled `libllama` and the Python converters. Upstream's `src/CMakeLists.txt` adds the new `llama-kv-cache-dsv4.cpp` itself (built via FetchContent). All four patches (`0001`–`0004`) apply unchanged; the project binds none of the new symbols.
 - `configureParallelInference` now applies `slot_prompt_similarity` live via `server_context::set_slot_prompt_similarity()` (upstream PR ggml-org/llama.cpp#22393, carried as `patches/0003` until merged), instead of validating it and discarding the value.
 - Extracted the `chatWithTools` agent loop into `ToolCallingAgent`; tool-result errors (unknown tool / handler exception) are now JSON-serialized so tool names containing special characters remain valid JSON.
