LLM-jp-4.1 uses the GPT-OSS format, but its tokenizer decodes a space
after every special token and parallel tool calls are separated by
<|end|>. The GPT-OSS handler rejects this output, so add a dedicated
handler, selected by the chat_format=llm-jp-harmony-v1 declaration in
the chat template.

* vocab : honor BOS/EOS settings for PLaMo-2 and PLaMo-3
The original tokenizer configs for PLaMo-2 and PLaMo-3 have
`add_bos_token: true` and `add_eos_token: false` , but
_set_vocab_plamo() did not write the BOS/EOS metadata. The
PLAMO2 tokenizer path also ignored add_bos/add_eos during
tokenization.
Write the settings from tokenizer_config.json and honor them in
the PLAMO2 tokenization path. GGUFs without these keys keep the
previous behavior.

The committed docs/ops/CPU.csv is out of sync with the current
test-backend-ops suite: 11 ops with CPU support (COL2IM_1D,
MUL_MAT_HADAMARD, SWIGLU_CLAMP, MUL_MAT_W4A4/W4A8, MUL_MAT_ID_W4A4/W4A8,
DSV4_HC_COMB/PRE/POST, LIGHTNING_INDEXER) are missing entirely, and
many other ops have fewer test cases than the suite generates now.
docs/ops.md (which CI requires to match the CSVs) therefore
understates CPU support.
Regenerated with:
test-backend-ops support -b CPU --output csv > docs/ops/CPU.csv
scripts/create_ops_docs.py
Note: ADD1 now reads unsupported on CPU because ggml_add1 is
GGML_DEPRECATED and the suite no longer generates test cases for it;
the CPU implementation itself is still present.

#27941 disabled -sm tensor for qwen4exp because test-llama-archs asserted on the
Meta device once the fixture carried a PLE layer:
GGML_ASSERT(ggml_backend_buffer_is_meta(tensor->buffer)) at ggml-backend-meta.cpp:476.
With host-resident embeddings the PLE gather is a CPU node and hc_init (the REPEAT
that fans the embedding out to the hc streams) was first reached through layer 0's
PLE path, after that gather. ggml_backend_sched_split_graph pass 2 expands a device
assignment upwards only until it meets a CPU node, so the REPEAT stayed on the CPU
and the later reshape of hc_init inside the meta split viewed a host-resident node.
Expanding hc_init right after it is built puts the REPEAT directly before the first
device node, where pass 2 assigns it; the embedding reshape stays in the CPU split
and is copied in as a split input, as in deepseek4.
dequantize_block_iq4_nl writes QK_K values per block, but a row can be shorter than that (an IQ4_NL row is only guaranteed to be a multiple of QK4_NL). Threads whose 32-value sub-block starts at or past k currently read and write past the end of the row. Skip those sub-blocks; for rows that are a multiple of QK_K the check never fires.

* convert: fix LoRA conversion crash for Qwen3.5 V-head reorder
_reorder_v_heads does reshape+permute+reshape to reorder V heads from
grouped to tiled order. LoraTorchTensor.reshape() cannot split its
row dimension (A matrix), so converting Qwen3.5 LoRA adapters that
target out_proj crashes with NotImplementedError.
Fix: detect LoRA tensors and apply the equivalent index permutation
directly — column reorder (dim=last) permutes A's columns, row
reorder (dim=0) permutes B's rows. This is mathematically identical:
(B @ A)[:, perm] == B @ A[:, perm]
(B @ A)[perm, :] == B[perm, :] @ A
Verified: both paths produce exactly zero diff against the full-tensor
reorder on random (rank=32, 4096×4096) matrices.

The sparse indexer mask is built with a set_rows scatter. Padded pools,
absent sequences and missing tail cells all pointed to the same n_kv
sentinel row, and invisible pools picked by top_k to fill the selection
overlap the tail cells of the token, so several CPU threads wrote the
same element (ThreadSanitizer data race in the sanitize CI).
Allocate the slot mask for both selection paths and route every dead
slot to its own dump row n_kv + slot. Live slots address disjoint cells,
so the scatter indices of a token are unique.

* cli: exit on stdin EOF and drop the console wide Ctrl+C broadcast
On Windows the simple input reader sends CTRL_C_EVENT to every process
attached to the console when stdin reaches EOF, killing unrelated
processes such as a supervising agent. The CLI only stopped on EOF
because of that self inflicted SIGINT; on POSIX, and with the advanced
reader, it spins forever printing prompts.
Drop the broadcast so both platforms just return an empty read, and
treat an empty read as EOF in the chat loop and the model selection,
since a submitted line always ends with a newline.
* cli: keep the newline of a trailing "/" and stop mtmd-cli on EOF
A lone "/" came back as an empty read and was taken for EOF, and
mtmd-cli only stopped on EOF through the removed broadcast.
The fixture recycles its two blocks over 8 cache slots, so the fp16
error builds up past the 1e-4 NMSE bound on the Vulkan T4 and WebGPU
jobs of Models Backend. Two l-cycles keep every branch of the cycle
loop and halve the error.

* ggml : add BF16 unary, GLU, binary and scale ops (CPU, CUDA)
* ggml-cpu : use per-op _bf16 functions for BF16 unary and GLU ops
Assisted-by: Claude Opus 5.5
* CUDA: use ggml_cuda_cast in binbcast and unary kernels to fix the HIP bf16 build
* ggml-openvino : reject BF16 SCALE and mixed-type BF16 ADD/MUL/SUB
* cpu: accept BF16 in src1 of mul_mat
ggml_conv_1d_dw builds its im2col in F32 when the kernel is BF16, then
calls ggml_mul_mat(im2col, kernel), which puts F32 in src0 and BF16 in
src1. The CPU backend refused that combination, so it was reported as
unsupported on every backend and never compared against anything.
Widen BF16 into the F32 work buffer, next to the existing packing of F32
into vec_dot_type. This is the arithmetic the Metal mat vec kernel
already uses, both operands promoted to float and accumulated in float,
so the two agree exactly rather than approximately.
Cover it with a conv_1d_dw test over F32, F16 and BF16 kernels, plus
three mul_mat cases with BF16 in src1.
* vulkan: reject BF16 in src1 of mul_mat unless src0 is BF16
supports_op only checked the src1 type for non contiguous tensors, so
a contiguous BF16 src1 was accepted and the pipeline lookup asserted.
The only BF16 src1 path is the BF16 x BF16 multiply, every other src0
type now reports the op as unsupported and the scheduler keeps it on
the CPU.
The BF16 kernel case of the conv_1d_dw test needs the f32 x bf16
mat vec variants of the Metal backend, which land separately.
This commit adds an optional --add-bos token command line option to the
run-org-model.py script.
The motivation for this is that there are models, for example Gemma4,
that explicitely set the add_bos value to true in llama-vocab.cpp even
if the original model does not set this value to True.
It would be nice to be able to force the models to agree on the bos
token so that logit verification can proceed.

* openvino: serve GET_ROWS on a weight view from the base Constant
Resolve view_src when collecting weight Constants so a view over a
quantized weight no longer becomes a dynamic typed Parameter, and fold
the row offset of the view into the gather indices instead of slicing
the dequantization subgraph.
* openvino: lift the quantized GET_ROWS view rejection
The supports_op rejection of a quantized src0 view with a nonzero
offset keeps the vs0 GET_ROWS cases of #28253 away from OpenVINO.
The weight view now resolves to the base Constant with the row offset
folded into the gather indices, so the rejection goes away.
#27773 adds the glm5-next arch without its rows in the Metal fusion
baseline, so test-fusion --check fails on it. The rows come from
test-fusion --record on an M5 Max, and --check passes 270/270.
