* chat: add dedicated Ling 3.0 (Bailing V3) parser
Ling 3.0 Flash templates pre-open the think block in the generation
prompt, so the model never emits an opening <think>, and a tool call can
arrive before any </think>. The generated autoparser terminated reasoning
only at the close tag, which classified such tool calls entirely as
reasoning_content: clients received content="" with no tool_calls and
agent loops died as reasoning-only turns.
Adds a specialized parser that terminates reasoning at the think close
tag or at a <tool_call> start, mirroring the hand-written Qwen3-Coder and
Kimi K3 parsers and the reference vLLM/SGLang Ling3 parser (which treats
<tool_call> as an implicit reasoning terminator). Detection is gated on
the <role>...</role> section markers, unique to this family among the
tagged-argument templates.
Adds the Ling 3.0 Flash chat template and tests covering the
unclosed-think tool call (full parse and streaming), healthy closed-think
paths, trailing prose, parallel calls, marker-like strings in argument
values, string-union and non-string argument types, and
reasoning_format=none.

* metal : add top-k MoE fusion
Adds a Metal fusion for SOFT_MAX + ARGSORT + GET_ROWS with optional
routing-weight normalization and scale, matching the top-k MoE fusion
available in the CUDA and Vulkan backends. The fused kernel writes the
selected expert ids and routing weights directly, eliding the separate
softmax, argsort, get-rows, sum-rows, clamp, div and scale kernels.

* metal : add MoE weighted reduction fusion
Fuses MUL(experts, weights) plus the expert VIEW/ADD chain into one kernel
that computes the weighted sum directly. The graph_optimize hook keeps the
expert and weight buffers alive until the fused output so the allocator cannot
reuse them while the kernel is still reading them.

* tests : expose MoE weighted reduction in fusion baseline
Use 2 experts per token in the generated MoE test models so the Metal
MoE weighted reduction fusion (MUL + ADD) is exercised by test-fusion.

* metal : fuse RMS_NORM + SCALE
Adds NORM/RMS_NORM + SCALE fusion to the Metal backend by reusing the
norm+mul kernel with a scalar scale flag. Adds test coverage for both
NORM+SCALE and RMS_NORM+SCALE and regenerates the fusion baseline.
Assisted-by: pi:llama.cpp/DeepSeek-V4-Flash-Vision-Exp
* metal : use function constant for RMS_NORM + SCALE
Replaces the runtime use_scale karg with a Metal function constant. The
norm+mul kernel is compiled with FC_norm_use_scale=false for MUL fusion and
FC_norm_use_scale=true for SCALE fusion, so the fused kernel has no runtime
branch.

* metal : use function constant for top-k MoE with_norm
Replaces the runtime with_norm karg with a Metal function constant. The
top-k MoE kernel is compiled separately for the normalized and non-normalized
routing variants, removing the runtime branch.

* metal : add MUL_MAT + UNARY and MUL_MAT + ADD + UNARY fusion
Adds dense mat-vec activation fusion for sigmoid/silu and bias+softplus.
The mat-vec kernels apply the activation/bias epilogue via function
constants, avoiding the separate unary/add passes.

* metal : revert MUL_MAT + UNARY and MUL_MAT + ADD + UNARY fusion
The mat-vec activation fusion regressed decode throughput on Qwen3.6-35B-A3B
by ~8% (tg32 81.5 vs 88.5 t/s). The regression is caused by loss of
concurrency: the standalone unary kernels previously overlapped with other
mat-vec work, while fusing the activation into the mat-vec kernel serializes
it on the critical path.

argsort_f32_i32_cuda_cub called the one-shot DeviceRadixSort::SortPairs
API with d_keys_in == d_keys_out (temp_keys, temp_keys). CUB's internal
double-buffer ping-pong requires distinct key buffers: with aliased
buffers the sort partially overwrites its own input mid-pass and emits a
corrupted permutation, surfacing as intermittent garbage indices (e.g.
backend top_k over a 248k-column vocab on Maxwell/CUDA 12.5/CCCL 2.x,
which then triggered out-of-bounds gathers in downstream get_rows).
Use a distinct keys-out buffer for all six call sites (plain and
segmented, ascending and descending, size-query and execute).

Allow HMX flash-attention to run with head_dim not a multiple of 64
(e.g. SigLIP head_dim=72), by operating on DK/DV rounded up to 64 with
zero-filled tail lanes.
* ggml-cpu: add F16 input to the FWHT
The CPU FWHT accepts F32 input only. This change makes the source type a
template parameter. The CPU path now accepts F16 input and F32 input.
The CPU MUL_MAT reference now converts an F16 src1 to F32. It does this when
the caller sets the Hadamard hint.
No backend has an F16 FWHT kernel yet. The test cases come with the backend
changes that add one.
* ggml-cpu: assert the F16 FWHT input path, and use the bulk converter
Address review feedback.
The F16 branch writes plain floats into wdata, which is only correct when
vec_dot_type is F32. That invariant held because supports_op only accepts an
F16 src1 for the Hadamard hint with F32 src0 and dst, but nothing enforced it.
Assert it next to the existing src1 type check so widening supports_op cannot
silently break the write.
Replace the hand-rolled conversion loop with ggml_cpu_fp16_to_fp32.
* llama: read the SWA pattern as a period or a per-layer array
Add llama_model_base::load_swa_pattern(), which reads
sliding_window_pattern either as one flag per layer or as a period
expanded by set_swa_pattern(), and use it in every loader that reads
the key as a period.
These loaders silently ignored an array and applied their default
period, although the converters of olmo2, gemma3n and exaone4 write
arrays. The published GGUFs match the defaults, so their outputs do
not change. The loaders that already accepted both forms lose their
duplicated scalar-then-array block, and use their declared default
period when the key is absent.
* model-saver: write the SWA pattern and the MLA SWA geometry
Write sliding_window_pattern as one flag per layer, nextn layers
included, for every model using SWA. The array is never collapsed to
a scalar, since the loaders read a scalar as a period.
Also write the MLA key/value lengths and KV LoRA rank of the SWA
layers, required by dots3note.
This enables the saver for plamo3, gemma3, cohere2, cohere2moe,
olmo2, exaone-moe, afmoe, mimo2, spark2_5, muse-glimmer, mellum,
laguna, granite_swa, dots3note and maple, all passing the bit-exact
roundtrip of test-llama-archs.
* vulkan: add IQ3_S MMQ matmul kernels
* Make block_a_to_shmem do 2-byte loads (110 bytes is divisible by 2)
* Align the check, IQ3_S is also using K tile size
* vulkan: raise the hoisted row-id limit for mul_mat_id to 512 experts
The expert-count shader (count_experts.comp) sizes its shared arrays
with BLOCK_SIZE, which is 256. Because of that, row-id hoisting is
switched off for any model with more than 256 experts, and every
mul_mat_id workgroup has to rescan the whole ids tensor on its own.
Qwen3.8-Flash-Next has 512 experts and was quietly running on that
slow path.
This change sizes the arrays with a separate MAX_EXPERTS constant (512),
clears them in a loop instead of one entry per thread, and raises the
matching limit on the host side.
On Strix Halo at batch 2048 the expert matmuls drop from 12.5 to 9.5 ms
(iq3_s) and from 14.0 to 7.5 ms (iq4_nl) per op, and prompt processing
gets about 19 % faster at 8k tokens. test-backend-ops MUL_MAT_ID passes
(891/891) with new 512-expert test cases.
Assisted-by: Claude Fable 5.1
* vulkan: raise the hoisted row-id limit for mul_mat_id to 1024 experts
Follow-up to review feedback: 1024 matches LLAMA_MAX_EXPERTS instead of
stopping at 512. The three shared arrays in count_experts.comp grow to
3 * 1024 * 4 = 12 KiB, which fits the 16 KiB that Vulkan guarantees for
maxComputeSharedMemorySize.
Adds mul_mat_id test cases at 1024 experts alongside the existing 512
ones. test-backend-ops MUL_MAT_ID passes on Vulkan (RADV, Strix Halo,
Radeon 8060S): 889/889.

* ci : add API/ABI check to make-release workflow [no ci]
This commit adds an API/ABI compatibility check to the make-release
workflow.
The motivation for this to allow us to detect any potential breaking
changes in API/ABI compatibility between releases and fail the the
release if there are any.
The workflow can be triggered manually as before and this check can be
skipped if needed as it does take some time which might be useful when
doing a dry-run and not specifically interested in the API/ABI check.
By default this will check the current release against the latest
release, but this can also be configured in the workflow, or in the
script run on the command line, to check a different tag.
* add check for minor version bumps [no ci]
This commit also changes the build type to be RelWithDebInfo so that the
reported information is more useful.
* gguf : align the data section relative to the GGUF start, not the file
gguf_init_from_file_ptr reads a GGUF from the current file position, but padded
the data section from file offset 0, so a GGUF embedded at an offset that is not
a multiple of the alignment loaded without error and returned wrong tensor data.
Also adds llama_adapter_lora_init_from_file_ptr, and disables mmap with a warning
when an embedded data section is not aligned, instead of asserting in ggml.

Both im2col.comp and im2col_3d.comp declare D_ptr without an explicit
buffer_reference_align, so glslang emits writes through it as Aligned
16. The shaders advance the pointer by D_SIZE, a per-variant define
set to 4 for float and 2 for float16_t, so most write addresses are
not 16-byte aligned. This triggers
VUID-RuntimeSpirv-PhysicalStorageBuffer64-06315 under GPU-AV.
Declaring buffer_reference_align = D_SIZE matches the alignment to the
actual write stride and takes validation hits from 20 to 0 for both
IM2COL and IM2COL_3D.
