* fix(ds4): build CUDA kernels for the target architecture
The ds4 backend compiled its CUDA objects with no -arch. Upstream's Makefile
leaves CUDA_ARCH empty and its `cuda` target refuses to build without one,
offering `cuda-spark` (sm_121) and `cuda-generic` (native) instead. We invoke
its object targets directly, which bypasses that guard, so nvcc fell back to
its default architecture and the kernels ran as JIT'd PTX on the real GPU.
On GB10 (sm_121) that silently corrupted inference: any prompt over roughly 128
tokens produced text unrelated to the input and never closed its thinking
block, so content came back empty and the chat showed only reasoning; longer
prompts failed with "cuda decode failed". It also cost close to two orders of
magnitude of prefill throughput. Measured on one box, same model, same prompt,
same GPU, upstream ds4 at the pinned commit, differing only in the nvcc flags:
make -B ds4 (archless, as we build it) garbage output 4.21 t/s
make cuda-spark (compute_121a/sm_121a) correct output 325.70 t/s
Select an architecture list from CUDA_MAJOR_VERSION, which the backend matrix
already declares for both ds4 cublas entries but Dockerfile.ds4 never forwarded.
Upstream's CUDA_ARCH takes a single value, so it cannot express the fat binary
these images need; NVCC_ARCH_FLAGS is overridden instead, since a command-line
assignment wins over its `:=`. The lists are copied from vllm-cpp rather than
invented so the two CUDA images cover the same GPUs, with l4t/arm64 covering
Orin, Thor and GB10. An empty CUDA_MAJOR_VERSION keeps upstream's `native`
behaviour for local developer builds, and no CI runner has a GPU to enumerate.
DS4_CUDA_HAVE_MXF4 is deliberately left unset: upstream defines it only for
single-arch sm_120/sm_121 builds and guards it with a plain #ifdef rather than
__CUDA_ARCH__, so it cannot be combined with older archs. It gates an optional
MXFP4 indexer fast path whose #ifndef branch returns 0 and falls back cleanly,
so omitting it costs speed on GB10, not correctness.

* test(ds4): cover the multi-batch prefill regression
The architecture fix has no automated guard: every existing e2e spec uses a
short prompt, and the miscompiled backend answered short prompts correctly.
The corruption only appears once a prompt spans more than one prefill batch,
so the whole suite passed against a backend that produced garbage in normal
use.
Add an opt-in "long_prefill" capability to the backend e2e suite that sends a
prompt well past one batch with a known needle and asserts the answer still
reflects it, and document in the ds4 guide why the build must never omit an
nvcc architecture, how to check which flags a configuration resolves to
without compiling, and how to run the new spec.

refactor(backends): extract shared package-system-libs.sh from package.sh
The arch-detect-and-copy-system-libs block (Darwin rpath / x86_64 / aarch64
loader + libc/libstdc++/libgcc_s/libm/libgomp/libdl/librt/libpthread) was
inlined verbatim in 31 backend package.sh scripts. Extract it into a single
sourced scripts/build/package-system-libs.sh, the CPU-side counterpart to
scripts/build/package-gpu-libs.sh and its sourcing contract.
Consolidating the copies fixes three drift classes that had crept in:
- libgcc_s.so.1 and libstdc++.so.6 were listed twice in 9 backends
(acestep-cpp, crispasr, moss-tts-cpp, omnivoice-cpp, piper,
qwen3-tts-cpp, silero-vad, stablediffusion-ggml, whisper); the shared
script copies each once.
- libgomp.so.1 was omitted from opus. OpenMP consumers dlopen it rather
than link it, so the missing copy only failed at runtime; the shared
script always includes it.
- the Darwin @loader_path/lib rpath was applied only in piper and
silero-vad; both now pass their packaged binary to the shared script,
preserving that behavior. Every other backend passes an empty binary
path so no rpath is added, preserving its current behavior.
Each backend's pre/post packaging steps (binary copy, run.sh, ldd closure
walks, ggml variant bundling, espeak/OpenBLAS extras, the ds4 validate step)
are preserved verbatim; only the inline if/elif/else arch block is replaced
by a single source line.

fix(distributed): reject wrong-model requests at the backend (#10952)
In distributed mode the controller caches a NodeModel row naming a backend's
host:port. A worker can recycle a stopped backend's gRPC port for a different
model's backend, and probeHealth verifies liveness rather than identity, so the
probe succeeds against whatever now occupies the port and the request is
dispatched to the wrong backend. The caller gets a silent wrong-model answer.
Nothing in the request could catch this: PredictOptions had no model field, so
model identity crossed the wire only in ModelOptions.Model at LoadModel time,
and the cached-hit path issues no LoadModel. Every backend's "model not loaded"
guard checks a nil handle, which a process holding a different model passes, so
the stale row was never dropped either.
Add PredictOptions.ModelIdentity and enforce it at the point of use:
- The controller populates it in gRPCPredictOpts from ModelConfig.Model, the
same expression ModelOptions feeds to model.WithModel and therefore the
same value the backend received as ModelOptions.Model. Both are read from
one config value in one function, so they are equal by construction and the
comparison cannot false-reject.
- Backends compare it against what they loaded and return NOT_FOUND with a
fixed sentinel. Enforced in pkg/grpc/server.go (27 Go backends), an
interceptor in backend/python/common (all 36 Python backends, no
per-backend change), and the llama-cpp / ik-llama-cpp / ds4 C++ servers.
That is every backend with real exposure: kokoros answers all four RPCs
with unimplemented and privacy-filter implements none of them.
- The router's reconcile drops the stale replica row on a mismatch, so the
next request reloads somewhere correct.
Empty means "skip the check" on both sides: a controller that predates the
field sends nothing, a backend loaded by such a controller has nothing to
compare, and the C++ server synthesizes PredictOptions internally for ASR. That
keeps upgrades working in both directions.
Scoped to the four PredictOptions RPCs. TTSRequest.model and
SoundGenerationRequest.model are deliberately NOT validated: FileStagingClient
already rewrites them to worker-local absolute paths, so in distributed mode
they already differ from the load-time value and comparing them would reject
valid requests.
IsModelMismatch requires both the NOT_FOUND code and the sentinel, unlike the
neighbouring helpers which accept either. insightface's Embedding returns
NOT_FOUND "no face detected" on a PredictOptions RPC, and a code-only check
would drop a healthy replica row on every faceless image.

feat(ds4): wire SSD streaming + quality engine options, add 128GB DeepSeek gallery models
The ds4 backend zero-initialized ds4_engine_options and exposed none of the
engine's tunable knobs, so SSD streaming (run a model larger than RAM by
streaming routed MoE experts from the GGUF on SSD) and the quality/perf knobs
were unreachable from LocalAI model YAMLs.
Map ModelOptions.Options onto ds4_engine_options through a declarative table
(kEngineOptSpecs + apply_engine_option) instead of per-field branches: the
struct is fixed C with no reflection, so the field set is enumerated once and a
future knob is a one-line table row. Two fields use ds4's own typed parsers
(GiB budgets, cache-experts count-or-NGB). Bare flags (e.g. "ssd_streaming")
mean true; path-type options (mtp_path, expert_profile_path,
directional_steering_file) resolve relative to the model directory so a gallery
entry can reference a companion file by bare filename. mtp_draft/mtp_margin are
now validated rather than parsed with throwing std::stoi/std::stof.
Add gallery entries for the 128 GB class:
- deepseek-v4-flash-q2-q4 (~91 GB, mixed q2/q4, fits RAM, higher quality)
- deepseek-v4-flash-q4-ssd (~153 GB full 4-bit, runs on 128 GB via SSD streaming)
- deepseek-v4-flash-q2-mtp (~81 GB + MTP speculative draft weights)
- deepseek-v4-pro-q2-ssd (~433 GB Pro, experimental SSD streaming)
SSD streaming is Metal (Darwin) only; the options are inert on CUDA/CPU.

* feat(ds4): wire grpc-server as distributed coordinator
Add distributed COORDINATOR support to the ds4 backend's gRPC server.
Distributed inference is an engine backend: when LoadModel receives
'ds4_role:coordinator', the process populates ds4_engine_options.distributed
(role, layer slice, listen host/port) before ds4_engine_open, then the normal
ds4_session_* generation path runs transparently once the worker route covers
all layers.
- New LoadModel options: ds4_role, ds4_layers (START:END or START:output),
ds4_listen (host:port), ds4_route_timeout.
- parse_layers_spec() maps the layer spec onto ds4_distributed_layers.
- wait_route_ready() blocks generation until
ds4_session_distributed_route_ready() reports full coverage (or timeout),
gating both Predict and PredictStream; returns UNAVAILABLE on timeout/error.
- No ds4_role => g_distributed stays false and wait_route_ready is a no-op,
so single-node behavior is unchanged.

* ci(bump-deps): register ds4 + move version pin into the Makefile
The initial ds4 PR (#9758) put the upstream commit pin in
backend/cpp/ds4/prepare.sh as a shell variable. The auto-bump bot at
.github/bump_deps.sh greps for ^$VAR?= in a Makefile, so DS4_VERSION
was invisible to it - other backends (llama-cpp, ik-llama-cpp,
turboquant, voxtral, etc.) all pin in their Makefile.
This change:
- Moves DS4_VERSION?= and DS4_REPO?= to the top of
backend/cpp/ds4/Makefile.
- Inlines the git init/fetch/checkout recipe into the 'ds4:' target
(matches llama-cpp's 'llama.cpp:' target pattern). Directory acts
as the target so make only re-clones when missing.
- Deletes the now-redundant prepare.sh.
- Adds antirez/ds4 + DS4_VERSION + main + backend/cpp/ds4/Makefile to
the .github/workflows/bump_deps.yaml matrix so the daily bot opens
PRs against this pin.
- Updates .agents/ds4-backend.md to point at the Makefile.
Verified:
$ grep -m1 '^DS4_VERSION?=' backend/cpp/ds4/Makefile
DS4_VERSION?=ae302c2fa18cc6d9aefc021d0f27ae03c9ad2fc0

scripts/changed-backends.js:inferBackendPath has an explicit branch per

matching branch the function returns null, the backend never lands in
the path map, and PR change-detection cannot map "backend/cpp/ds4/X

This is why PR #9761 produced zero ds4 jobs even though it directly
edits backend/cpp/ds4/Makefile.
Adds the missing branch (Dockerfile.ds4 -> backend/cpp/ds4/), placed
before the llama-cpp branch (since both share the .cpp ancestry but
ds4 is more specific - same ordering rule documented in
.agents/adding-backends.md).
Verified with a local Node simulation of the script against this PR's
diff: the path map now contains 'ds4 -> backend/cpp/ds4/' and a
'backend/cpp/ds4/Makefile' change correctly triggers the ds4 backend
in the rebuild set.
