📝 WalkthroughWalkthroughChangesThe PR adds the Gated Delta Rule operation across the core API, Linalg IR, JSON persistence, CPU backend, and Qwen3.5 GDN path. It adds stateful execution support and expands CPU, neural-network, configuration, tokenizer, and multimodal test coverage. Gated Delta Rule operation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This refactor moves Qwen3.5 inference onto stateful runtime operations, but the current revision is not merge-ready because its Qwen3.5 GDN test targets are no longer registered, Android test execution is not configured, and a failed forward pass can leave later inference using partially advanced state. These issues should be fixed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

Document the stateful operation contract. Add API documentation for the required ordered inputs and tensor layouts, the roles of a, b, A_log, and dt_bias, the sequence and updated-state outputs, and the exact state_inplace behavior: true mutates and aliases caller-owned state, while false preserves the input and returns independent updated storage. Also document validation errors so callers can use the operation safely. Apply the same contract to the functional declaration, operation type, and layer declaration.

Assert recurrent-state equivalence for each repeated run.
This loop compares only output. A parallel execution path can corrupt the returned recurrent state while preserving the tested output projections. Compare layer_state with layer_ref_state after each run.

Restore the Qwen3.5 GDN test registrations.
tests/cpu/CMakeLists.txt removes Mllm-Test-Qwen35-GDN and Mllm-Test-Qwen35-GDN-Conv, but this file registers only the configuration, tokenizer, and multimodal targets. CPUKernelFocused runs generic kernel tests and does not replace the removed Qwen3.5-specific test executables. Add and register both targets here, or confirm their new CMake owner.

CMake add_test COMMAND executable target CROSSCOMPILING_EMULATOR behavior when unset official documentation
💡 Result:
When using the add_test command with an executable target, the behavior regarding the CROSSCOMPILING_EMULATOR target property is as follows: If the CROSSCOMPILING_EMULATOR property is unset (not defined) for an executable target, CMake will execute the target directly without any emulator prefix [1][2][3]. Under current CMake versions (3.29 and later), the use of the CROSSCOMPILING_EMULATOR property is governed by policy CMP0158 [4]. The behavior depends on whether the project is cross-compiling: 1. When cross-compiling: If the CROSSCOMPILING_EMULATOR property is set, CMake automatically prefixes the test command with the specified emulator [1][2][3]. If it is unset, no emulator is used, which typically results in the test failing if the executable cannot run natively on the build host [2]. 2. When not cross-compiling: CMake ignores the CROSSCOMPILING_EMULATOR property (even if set), adhering to the NEW behavior of CMP0158 [4]. In this case, the test is executed directly without an emulator [4]. For older CMake versions (3.28 and below), or if policy CMP0158 is set to OLD, the CROSSCOMPILING_EMULATOR property is used unconditionally regardless of whether the project is cross-compiling [4]. However, even in these cases, if the property remains unset, no emulator prefix is applied to the test command [1][2]. Note that this behavior only applies to the modern add_test(NAME COMMAND ...) signature; the legacy form of add_test does not support target properties like CROSSCOMPILING_EMULATOR [2][3].

Guard GatedDeltaRuleFocused on Android. The Mllm-Test-Nn-GatedDeltaRule target has no CROSSCOMPILING_EMULATOR property or device runner, so CTest may execute the Android binary directly on the host and fail. Use the project’s non-Android guard or configure the Android test runner.

Resolve the CausalDepthwiseConv1D add/add conflict in favour of the upstream weighted operation (UbiquitousLearning#701/UbiquitousLearning#704): Ling's q/k/v short convolutions now register nn::CausalDepthwiseConv1D directly (current-first order, in-place [B, C, K-1] history) instead of the branch-local weight-as-input variant, and the branch-local Functional/IR/serialization entries for it are dropped. KimiDeltaAttention moves to OpType 81 because upstream retired value 76. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Split the branch-local Ling3KDATest into the layers that the repository now maintains separately (UbiquitousLearning#704/UbiquitousLearning#706): - tests/cpu/KimiDeltaAttentionKernelTest.hpp: scalar-reference fixture for the KDA kernel (both gate variants, NEON lane blocks and tails, bitwise prefill-vs-tokenwise and serial-vs-parallel checks, argument validation), registered in KernelTest.cpp and the CPUKernelFocused ctest filter. - tests/nn/KimiDeltaAttentionTest.cpp: public nn::KimiDeltaAttention contract through a Module (eager reference match including the 16x128 production head geometry, in-place vs copied state, chunked prefill/decode equivalence, invalid geometry/options, trace plus option serialization round trip), registered with add_test. - tests/models/ling3: config, tokenizer and RoPE tests with add_test registration, the `ling3` label, and an MLLM_LING3_EXAMPLE_DIR override for on-device runs. The causal-convolution contract is covered by the upstream tests/nn/CausalDepthwiseConv1DTest.cpp and the CausalDepthwiseConv kernel suites, so the branch-local copies are removed.

Ling's two reusable stateful primitives no longer call CPU kernels from model code. KimiDeltaAttention becomes a formal mllm operation (OpType 81; upstream retired value 76) with nn::Layer / Functional frontends, aops contract, linalg IR, option serialization/interpreter reconstruction, and a typed CPU factory whose backend op calls the existing KDA kernel. The q/k/v short convolutions register the upstream weighted nn::CausalDepthwiseConv1D (UbiquitousLearning#701/UbiquitousLearning#704) with the current-first accumulation order and in-place [B, C, K-1] history, so they keep running on the existing optimized GDN convolution kernel; no convolution operation or kernel is added by this branch.

* refactor(minicpm5): move model-contract tests under tests/models Follow the test placement introduced by #704: MiniCPM5 configuration, tokenizer, and model-graph tests protect the model contract, not a CPU kernel, so they now live in tests/models/minicpm5 with their own CMake targets and CTest registration (label `minicpm5`). tests/cpu keeps only kernel and backend-op coverage. The config and model tests accept an MLLM_MINICPM5_EXAMPLE_DIR override (same convention as Qwen35ConfigTest) so the binaries can locate the example config when run outside the build host. No change under mllm/; the MiniCPM5 model graph already composes registered nn layers only. * test(cpu): add GQA decode kernel oracle to the unified kernel suite The native KV-head grouped-query-attention decode kernel (gqa_decode/fwd_bhsd.hpp) shipped with MiniCPM5 without kernel-level coverage; only the public nn::GroupedQueryAttention tests exercised it. Add GqaDecodeKernelTest.hpp following the neighbouring fixture shape: - independent double-accumulating scalar reference over a focused geometry matrix (scalar path, exact NEON blocks, qk/value tails, single KV head, 128-dim heads at several cache fills); - native static-cache view plus transposed [B, 1, H, D] query strides must match the contiguous computation bitwise; - grouped (batch, kv-head) slices must match per-head single-KV calls bitwise, proving scratch rows do not leak across heads or batches; - repeat stability and rejection of invalid geometry, null buffers, and unsupported strides without touching the output. Register the cases in KernelTest.cpp and extend the CPUKernelFocused filter so CTest runs them. * test(nn): register GroupedQueryAttention and KVHeadStaticCache with CTest Both public-operation test executables introduced with MiniCPM5 were built but never registered, so `ctest` skipped them. Register them the same way as GatedDeltaRuleFocused, under the `nn-op` label. * test(cpu): align GqaDecodeKernelTest with the neighbouring fixtures Replace the Run state bag and invoke() wrapper with a StridedView (storage plus the [B, H, S, D] strides under test), purpose-named view builders for the contiguous, static-cache, and transposed layouts, and explicit fwdBhsdFp32 calls in every case so the kernel contract is visible at the call site. Make the fixture class forward through non-static members with namespace-qualified types, matching GatedDeltaRuleKernelTest and CausalDepthwiseConvCurrentFirstKernelTest. Case names and assertions are unchanged.

Summary
Refactors the existing Qwen3.5 GDN path to use standard mllm runtime operations instead of calling CPU kernels directly from model code.
This PR:
GatedDeltaRuleas a first-class Layer/AOp/IR/backend operation;CausalDepthwiseConv1Doperation with Qwen3.5's current-first accumulation order;tests/cpu, the public operation undertests/nn, and Qwen3.5 product contracts undertests/models/qwen3_5.Standard mllm abstraction

The operation accepts eight inputs:
q,k,v, decay gatea, update gateb,A_log,dt_bias, and recurrentstate. It returns the sequence output and the updated state.state_inplace=falsepreserves the input state and returns updated independent storage.state_inplace=truealiases the updated-state output to the input state.Review map

A clean macOS/Apple Silicon build completed for every affected test target, and all 52 registered focused tests passed. The abstraction-boundary audit reported 0 errors and 0 warnings.CI, Android cross-build, target-device generation, and performance profiling have not been run for this refactor commit and remain separate evidence gates.
Validation (PASS) — 52 focused host tests and architecture audit
GatedDeltaRuleoperationMllm-Test-Qwen35-GDN*CPU targets no longer existCTest registration now owns the focused suites instead of only compiling standalone Qwen3.5 test binaries.
The fresh build directory reused a verified local
stdexecmetadata file after the dependency download produced an empty file; no mllm object or test binary was reused.Supported scope and limits
Supported by this PR: float32 contiguous CPU execution for the existing grouped-head GDN contract; explicit copied or in-place recurrent state; tracing and serialized reconstruction; Qwen3.5 model composition through registered operations.
Not changed: the existing GDN and causal-convolution kernel mathematics, Qwen3.5 checkpoint conversion, tokenizer, multimodal pipeline, or model support envelope.
Not claimed: new model capability, numerical parity against a full reference-model run on this exact commit, Android/device validation, model-quality improvement, or performance improvement.
