A Q4_0-mtp style tag now resolves the sidecar file when no model file matches it, so a solo draft or mmproj download actually pulls the file. Cached sidecar files list as their own entries so the state survives a restart, and removing such a tag deletes only the sidecar.

* tests : run test-recurrent-state-rollback over all dummy models
Add a --models DIR mode that mirrors test-save-load-state: iterate every

fails. Register a single ctest entry with ARGS --models instead of the four
per-model registrations.

* cont : fix typo
* metal : allow fusing 0-element nodes to keep graph packing shape-independent
The fusion packing in ggml_metal_fusion_max excluded 0-element tensors and
the topk_moe/moe_reduce checks rejected n_tokens == 0, so graphs decoding
batches with no outputs packed differently from the worst-case reserved
graph. The Metal optimizer then reordered the nodes differently and
ggml_gallocr_needs_realloc failed on the layout mismatch, forcing an
unexpected graph re-reserve (caught by GGML_SCHED_DEBUG_REALLOC).
Treat empty tensors like their non-empty counterparts: match them in the
pattern sequence and only reject genuinely malformed shapes. Fused kernels
dispatch zero threadgroups for empty graphs, which is a legal no-op.

* tests : run test_multi_seq_split_replay as a separate test
test_multi_seq_split_replay was invoked at the end of test_rollback,
so its result was folded into the rollback status and it only ran when
the rollback part passed.
Give it its own test_status return, run both tests independently over
both cache fills via a shared run_tests helper, and report them as
separate rollback / split replay columns in the --models table with
per-test summaries. The exit code fails when either test fails.

* tests : loosen the split replay nmse bound to 1e-4
test-generate-models seeds its weights from std::random_device, and some
generated lfm2 models drift up to ~1.7e-5 nmse on the split replay due to
rounding noise, tripping the previous 1e-5 bound. Raise the bound to 1e-4
so the random generations stop flaking.

* tests : reuse run_tests_for_model in single-model mode
The single-model path duplicated the model init and the non-recurrent
check from run_tests_for_model; route it through the shared helper
instead. Model load failures now return FAIL rather than SKIP so that
--model with a broken file still exits non-zero, and the helper loads
with model_only like the --models loop does since the tests create
their own contexts.

* ggml-cpu: enable tiled flash attention for non-vector-multiple head dims on x86
* add AVX2 support for masked loading and storing in simd_gemm_ukernel_tail
* ggml-cpu: fix FA softcap handling for padded KV tiles
* metal: support left and circular padding in GGML_OP_PAD
Align Metal with CPU, CUDA and Vulkan: shift the source coordinates by
the left paddings, wrap them around with the same wrap_around when
circular, and read the source through nb00, which also fixes a right
padding of a permuted source. A test case covers it.
Drop the f32_4 kernel: its selection is disabled as slower, and it
fails two pad cases once enabled.
* metal: use a function constant for the circular pad variant
Address review from ggerganov: replace the bool template with FC_PAD,
as FC_upscale_aa does, so the pad kernel is compiled once and
specialized per pipeline.
* vulkan: read the batch stride of an in place src0 from nb[2]
A dim01 contiguous tensor can still be a view whose batches are
strided by more than ne[1] rows, the first rows of a KV cache for
example. Both the mat-vec and the matrix paths read such a tensor in
place but passed ne00*ne01 as the batch stride, so every head past
the first read the wrong rows. The same applies to src1. The stride
now comes from nb[2] whenever the tensor is used in place; the value
is unchanged for a contiguous tensor.
test-backend-ops gets an m_v parameter on test_mul_mat, the number of
rows of a in memory, and two cases at the shapes of a decoder self
attention over a cache.
* vulkan: size the in place A and B ranges by their strided extent
The matrix path bound src0 and src1 to the shader with a range of
elements times type size, which ends before the batches of a strided
view. Pipelines with bounded access read zero past that range, so the
same view that the mat-vec path already handles gave wrong results
on Intel and on NVIDIA without coopmat2. The range now comes from
ggml_nbytes when the tensor is read in place.
* vulkan: address review from jeffbolznv
Bind the in place A and B of the matrix path with ggml_vk_subbuffer,
which spans to the end of the buffer, so a strided view is in range
without computing its extent.
mul_mat_id reads the batch stride of an in place src0 and src1 with
the same helper as mul_mat. test_mul_mat_id gets an m_v parameter,
the number of rows of as in memory, and a case whose experts are
strided by more rows than it uses.
* vulkan: read the batch stride of an in place src0 in mul_mat_vec_id
The single token path of mul_mat_id passed ne00*ne01 as the batch
stride of A, so a strided expert view read the wrong rows. The stride
now comes from ggml_vk_batch_stride like the other three paths, and
src1 follows the same rule.
test_mul_mat_id gets a single token case over the strided view.
* vulkan: address review from jeffbolznv
The batch stride of an in place tensor is taken from nb[2] as
nb[2] / type_size * block_size, which holds when nb[2] is padded and
not a multiple of nb[1]. A test_mul_mat case with a padded batch stride
covers it.
* vulkan: keep the A and B ranges exact in mul_mm
The quantized A loads of mul_mm carry no row bound and rely on the
descriptor range to read zeros past the last row of a partial tile.
Binding A and B up to the end of the buffer let those tiles read the
leftovers of a previous node and hung the NVFP4 mul_mm on NVIDIA
without coopmat2. The range is the strided extent of a tensor read in
place and the staged size otherwise.

* cuda: add F16 input to the FWHT
The CUDA FWHT accepts F32 input only. This makes the source type a template
parameter, so the kernel reads an F16 source directly instead of requiring a
converted copy. The F32 path is unchanged.
supports_op accepts an F16 src1 against an F32 src0 for the Hadamard hint.
Every other F16 src1 against a non-F16 src0 is still refused.
ggml_cuda_op_mul_mat_use_fwht is the single predicate both supports_op and
the dispatch call now share, checking contiguity and same-shape(src1, dst)
in addition to the type/hint conditions above. Without a shared predicate,
supports_op could admit an op that ggml_cuda_op_fwht then rejects only after
the unconditional same-shape assert has already fired; that gap predates
this change (it applies to the existing F32 path too) but this PR is what
touches supports_op, so it closes it here.

which resulted in different greedy transcripts for 4.5% of English and 6.5% of Japanese
test utterances. In Japanese, some differences changed entire words.
This change:
* uses `log(x + 2^-24)` instead of clamping to the log floor
* uses a symmetric Hann window, equivalent to `torch.hann_window(periodic=False)`
* adds the normalization epsilon to the standard deviation instead of inside the square root
Only the `lfm2a` preprocessor opts into these behaviors. Other audio preprocessors are unchanged.
Tested on top of 84e76d8 using `llama-server` with CUDA and `temperature=0`, compared against
http://github.com/Liquid4All/liquid-audio fp32.
Test set:
* 200 LibriSpeech `test-clean` utterances (EN)
* 200 Common Voice `ja` test utterances (JP)
* identical 16 kHz audio passed to both implementations
| Greedy transcript identical to `liquid-audio` | Without fix | With fix |
| --------------------------------------------- | ----------: | ----------: |
| EN F16 | 191/200 | 200/200 |
| JP F32 | 187/200 | 200/200 |
| JP F16 | 187/200 | 199/200 |
The remaining JP F16 difference is a comma and matches the reference implementation's own bf16
output.
Mel relative L2 error versus `liquid-audio`:
* EN: 3.2% -> ~2e-6 median
* JP: 3.9% -> ~2e-6 median
* metal: FWHT kernels for block widths above 512
The Metal FWHT covers widths 64 to 512, one row per simdgroup with N/32 values
per lane. Wider blocks need more registers per lane than that layout allows.
kernel_fwht_tg runs one row per threadgroup with 256 threads, so each thread
keeps N/256 values. Butterflies below the simdgroup width still shuffle, those
up to the threadgroup width go through threadgroup memory, and the rest stay in
registers. Same butterfly and sign convention as the simdgroup kernel.
Widths 64 to 512 keep the simdgroup kernel. 1024 through 8192 use the new one,
for both F32 and F16 sources.
The wide kernels allocate float[N] of threadgroup memory, 32 KB at 8192, so the
size check takes the device limit and reports those widths as unsupported where
they would not fit. Without that a device with less threadgroup memory would
accept the op and then abort on a nil pipeline.

* test-save-load-state : print a per-model results table in --models mode
in --models mode the output was very heavy: every model printed its
token dumps, per-test headers and PASS lines. instead, silence all
logging except the table itself (common_log_set_verbosity_thold(0)
leaves only LOG / LOG_LEVEL_OUTPUT) and print one row per model with
one column per test, colored PASS/FAIL/SKIP cells, row by row.
- run_save_load_tests_for_model returns a test_suite with a dynamic
std::vector<test_status> and continues past failures: tests 3-5 are
SKIPped when the baseline (test 1) fails, model init failure skips all
- per-test token dumps, test headers and PASS lines are demoted to
LOGV(LOG_LEVEL_INFO, ...) so they still show in single-model mode
- the table header/rows derive their columns from test_names; the
model name is printed and flushed before the suite runs so the model
currently in flight is always visible
- single-model output and exit codes are unchanged

* metal: add F16 input to the FWHT
The Metal FWHT kernel accepts F32 input only. This change makes the source
type a template parameter, so the kernel reads an F16 source directly instead
of requiring a converted copy. The F32 instantiations are unchanged.
The pipeline name now carries the source type, and supports_op accepts an F16
src1 for the Hadamard hint at the four sizes the kernels cover. Every other
F16 src1 path still goes through ggml_metal_supports_mul_mat_op.
These are the test cases mentioned in #27779.
test-backend-ops on M5 Pro: MUL_MAT_HADAMARD 16/16, MUL_MAT 1265/1265.
* metal: ask the same FWHT question in supports_op and the dispatch
supports_op admitted an F16 src1 on the type, the hint and the width alone, but the
dispatch also requires src1 and dst to be contiguous and the same shape. A Hadamard
hinted MUL_MAT that passed the first and failed the second reached the generic path,
which has no F32 src0 by F16 src1 kernel, and aborted on a nil pipeline:
kernel not found in any metal library: base = 'kernel_mul_mv_f32_f16_4'
ggml_metal_encoder_set_pipeline: nil Metal pipeline
ggml_metal_use_fwht now holds the whole condition and both callers use it, so they
cannot drift apart again. The added test case has src1 and dst of different shapes,
which aborted before this change and is declined by the Metal backend after it.
* metal: branchless butterfly select in the FWHT simdgroup kernel
Review suggestion. Replaces the ternary in the shuffle stages with
val2 - val + 2*((lane & i) == 0)*val, which is the same value without the
select.
Measured on M5 Pro, interleaved A/B, five rounds, first discarded, on a
Hadamard matmul with block 512 and 65536 rows so the kernel rather than the
launch dominates: 1324.6 us before, 1285.0 us after, a 3.0% gain, and faster
in every round. At the shapes already in the perf suite the op runs 1.6 to
3.9 us against a 1.6 us launch floor, so the difference is not visible there.
FOR_UNROLL on the same loops was also measured and made no difference, the
delta changing sign between rounds, so it is not included.
* metal: move the FWHT dispatch predicates to ggml-metal-common
Review feedback. ggml_metal_use_fwht and ggml_metal_fwht_supported_size were
static inline in ggml-metal-device.h. They now follow the
ggml_metal_op_mul_mat_use_mm pattern: declared in ggml-metal-common.h and
implemented in ggml-metal-common.cpp, which is already the home for helpers
shared between supports_op and the op dispatch. The predicate is named
ggml_metal_op_mul_mat_use_fwht to sit alongside the _use_mm pair it parallels.
This also fixes the macos-latest-arm64 build. The header needed ggml-impl.h
for ggml_get_op_params_i32, but ggml-metal-device.h is reached from
tools/tuning through ggml-metal-tuning.h, and that target does not have
ggml/src on its include path. ggml-metal-common.cpp already includes
ggml-impl.h, so the accessor is used normally there and the header goes back
to needing nothing extra.
* metal: keep the FWHT size check internal and group the dispatch helpers
Applies the patch from the review. ggml_metal_fwht_supported_size becomes
static in ggml-metal-common.cpp since nothing outside it needs the size list,
which also drops stdint.h from the header again, and
ggml_metal_op_mul_mat_use_fwht joins the existing _use_mm declarations under
their shared comment instead of carrying its own block.
* tests: drop the mismatched-shape Hadamard case
I added a case with m != k to cover an abort, but the hint is a promise that
src0 is a Hadamard matrix, so src0 is square and dst has the same shape as
src1. Every other case in the suite holds to that. The case was not a valid
op, and on CPU it compared the FWHT against a real matmul of a non-square
src0, which cannot agree.
The supports_op and dispatch conditions still come from one predicate, which
is what keeps them from disagreeing on contiguity.
* 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

* 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.

* 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 : rename moe_weighted_reduction suffix to moe_reduce
Shortens the MoE weighted-reduction fusion identifiers, kernel, pipeline,
matcher, args struct, and test op name from moe_weighted_reduction to
moe_reduce.

* 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.

* metal : add SSM_CONV + UNARY (silu) fusion
The SSM_CONV kernels apply silu directly via a function constant, eliding
the separate unary pass. Regenerates the fusion baseline.

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.
* 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.

* 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.
