* model : add H2O-Lightning-4B decision model
Adds the h2o-lightning decision type for h2oai/h2o-lightning-4b
(Qwen3.5-4B with a merged decision LoRA).
None of the existing types match this model. It answers with " A"
rather than "A", uses up to 255 labels, and was trained on Python
json.dumps text, so floats like 12.0 must render as 12.0.
The converter writes the decision metadata and the systemone template
from the model's serve_config.json and refuses a config that doesn't
match. Tests skip unless the tiny test model is available locally.

The __ARM_NEON branch defines both GGML_CPU_COMPUTE_* macros but selects
only FP16_TO_FP32, so FP32_TO_FP16 falls through to the portable
software conversion while neon_compute_fp32_to_fp16, a single fcvt,
stays defined and referenced by nothing. __POWER9_VECTOR__ and
__riscv_zfhmin select both.
Add an #error pair that refuses a branch defining a COMPUTE macro
without selecting it. That is how this stayed unnoticed: the fallback
silently supplies a correct software implementation, so the only
symptom is a hardware instruction nothing ever reaches. The
FP16_TO_FP32 half carries a !defined(__F16C__) carve-out, because PR
30343 keeps that direction on the lookup table on purpose.
Replace the comment above the fallback: it singled out NEON and POWER9
and pointed at a selection that now happens in the branch itself.

* server : pass id_slot through the Anthropic /v1/messages conversion
server_chat_convert_anthropic_to_oai copies a small whitelist of common
params from the Anthropic request into the internal OAI-style body and
left id_slot out. Every other completion endpoint honours id_slot; a
proxy that pins a session to the slot holding its KV cache needs the
same on /v1/messages, or it silently falls back to automatic slot
selection and, on hybrid/recurrent models, pays a full re-prefill.
Adds a test asserting a request with id_slot set is served by that
slot, observed via GET /slots.

* tests : make MoE router selection independent of the backend noise
The router scores are in the range [0, 1), so a random draw can leave the
last expert (or expert group) still selected and the first one dropped tied
within the noise between the backends. They then route a token to different
experts and the logits differ by 4e-3 instead of the usual 5e-7.
Beam is the only arch here with a real top-k (8 experts, 2 used) and a group
top-k (4 groups, 2 used), so it is the only one that hits this: 2 of 20 seeds
failed on an M2 Ultra, the other MoE archs select 2 of 2 and cannot tie.
Fill the selection bias with a ramp of step 2 to give every expert a score
range of its own, which turns the top-k into a function of the expert index
alone. The bias affects only the selection, the weights still come from the
unbiased probs, so the MoE output keeps its magnitude. Beam now matches the
CPU reference within 4e-7 for all of 160 seeds.

* tests : tell the CPU and the GPU of an Apple SoC apart in the device table
Both devices report the same description ("Apple M2 Ultra" here), so the
device column of the test table had two indistinguishable rows and a failing
row did not say whether the Metal device or the host CPU produced it.
Add the device name, which is also what -b takes, unless the description
already is the name.

* server: do not advertise a connect code without the tunnel
--connect-code on its own had no effect other than being served in
/props, so the Web UI showed a remote access code that no tunnel was
serving. Clear it when --connect is off, and say so once at startup.
The teardown comment claimed that terminate() closes the child stdout.
It does not: the log thread leaves fgets() only once every writer of
that pipe is gone, so a descendant of llama-connect would block the
join forever. Describe the real contract instead.
Also restore the --reasoning-preserve default in the generated docs.

In the attachment preview, SyntaxHighlightedCode's wrapper (overflow-auto) was not the element that ended up owning horizontal overflow: the inner code box kept its content clipped at the wrapper's width, so a single line longer than the preview pane was cut off with no scrollbar (scrollWidth == clientWidth while the code's own content measured tens of thousands of px).
Give the pre/code boxes their intrinsic width (width: max-content, min-width: 100%) so long-line overflow propagates to the scrolling wrapper. Verified in the running WebUI: with a 6000-char line, wrapper scrollWidth goes from 990 (clipped, unscrollable) to 50449 with a working horizontal scrollbar; short content still fills the container exactly as before (min-width: 100%).
Fixes#30796
The fused moe_reduce kernel computes dst = sum(experts[e] * weights[e]) in a
single dispatch, reading experts and weights while writing dst. The graph
allocator computes tensor liveness on the unfused graph, where the inputs are
fully consumed by earlier nodes of the fused group, so it can legally recycle
the input memory as dst. In the fused kernel this becomes a
threadgroup-vs-threadgroup race that produces rare non-deterministic wrong
results (observed with test-llama-archs -a kolibri on the meta backend).
Reject the fusion when dst overlaps either input, same guard as the
mul_mat_add fusion. The unfused MUL + ADD path is always correct.

* cuda: cap Stream-K blocks at the number of k-blocks
Stream-K normally launches one CUDA block per SM. For small matrices,
this can exceed the total number of output-tile/k-block pairs, leaving
blocks with no work and adding launch and fixup overhead. Cap the grid
at that count to remove these excess blocks without changing the useful
rounded K ranges or numerical results.

* cuda: cap Stream-K blocks at the number of k iterations
Cap the grid at the number of K_vram iterations across all output tiles, rounding up partial iterations. This removes extra CUDA blocks left by the k-block cap.
Partial iterations can change FP32 summation grouping. MUL_MAT and MUL_MAT_ID backend tests pass on RTX 5090.

* The problem here in the repo is gguf-split can silently produce corrupted tensor output when the input GGUF file is truncated. The fix is to add tensor-data bounds checks and short-read checks in gguf-split.cpp and export-lora.cpp, and a regression test that checks truncated input is rejected and valid tensor data is preserved.#
