…ed AdamW routing - `basis_type` accepts `bessel/fix` and `gaussian/fix`, which keep the Bessel frequencies or Gaussian centres at their initial values instead of training them: the dpmodel parser resolves the family and the flag, the PT `RadialBasis` and the pt-expt parameter promotion of DPA4 and DPA4C freeze the parameter, and it keeps its name and shape so checkpoints load under either form. - `env_exp` accepts a single integer: one C^3 envelope on the message-passing edge weights and a bare radial basis. The fused CUDA edge-radial kernel accepts an empty basis-envelope series. - `HybridMuonOptimizer` takes `adam_patterns`; the model bases of both backends compose the patterns their descriptor declares through `adam_route_patterns()` (DPA4: the first radial-embedding layer and the env-seed radial projection; DPA4C: the first radial-embedding layer), spin models delegate to their backbone, and both trainers pass the patterns to the optimizer. Nothing is written in the input. - Presets `v20260911`: DPA4 with `env_exp` 5 and `gaussian/fix` on the `v20260901` normalization settings; DPA4C with `gaussian/fix`. The HybridMuon routing patterns are read from the unwrapped model wrapper, so that DDP and FSDP training build the optimizer.
… export The padded forward skipped the radial embedding, the environment seed, the geometric initial embedding and the interaction blocks whenever a frame held no valid edge, so an isolated atom was a different function of its features in an edge-free frame than in a frame with other edges, and the descriptor jumped when the last edge of a frame left the cutoff. The dpmodel and sparse-edge paths never had the shortcut. The padded path now takes the same route for any edge count, the special empty cache is gone, and the Triton radial mixer reshapes with the explicit rank so that an empty edge set is well defined. The fused radial function and the Wigner table builders cache constant tensors on first use. Under the freeze the first make_fx trace built them as fake tensors bound to that trace, the with-comm trace reused them, and torch.export rejected the mixed fake modes, so `dp --pt freeze` of a DPA4 model failed on a CUDA target. Constants built under a tracing mode are now returned without being cached. The scalar SO(3) read-out product is written as a weighted product-sum instead of a three-operand einsum: the contraction-path search of the latter guarded on the symbolic atom count and broke the with-comm export whenever the fused kernels are off (CPU targets included).

The remaining Python group 11 failures are addressed in 7afe4f6. Both failures were in the binding-selection unit test: it mocked op_available=True on the CPU-only build but still performed real native registration. Moving registration to binding initialization exposed this incomplete mock; a CUDA-enabled local installation concealed it. The test now mocks registration alongside availability, retaining all fp32/fp64 selection assertions. Production kernel and dispatch code are unchanged. Reproduced the exact missing-operator error in an isolated process without loading the local native library: before, 2 failed / 2 passed; after, 4 passed. The normal CPU run passes 10 tests (7 GPU-only skips), and the actual CUDA regression passes 15 tests (2 cuTile cases deselected). All pre-commit hooks pass. The Test CUDA label is being triggered for this commit to run the repository's full GPU CI. |

The DPA4 v20260901 presets are deprecated and removed in favor of v20260911. Given the short interval between these versions, we do not expect downstream adoption of these DPA4 presets and do not consider a compatibility layer necessary. To keep the catalog clean, their definitions are deleted outright, without deprecated aliases or fallback mappings. DPA4 retains v20260820 and v20260911; DPA4C retains both v20260901 and v20260911. All 24 retained configurations are unchanged. The v20260911 sizes are Nano, Mini, Neo, Air, Plus, Pro, Max and Ultra for DPA4, and Nano, Mini, Neo, Air and Plus for DPA4C. The model documentation uses compact version/available-size tables, without parameter-by-parameter release descriptions. The DPA4C water example selects dpa4c-nano-v20260911 and supplies only run-specific overrides, so no explicit Neo widths override the preset. Generated JSON schemas and editor completions follow the retained catalog. Validation: 96 preset/schema/doc-generator/example tests and 219 subtests passed. The retained preset definitions match the original catalog exactly; both documentation tables match the registry. The official VS Code JSON language service validates the example and offers 24 preset completions. |

Final local validation on PyTorch 2.13.0+cu130: 14 PT compile/embedding tests; 80 PT-expt export/model tests (including real CPU/CUDA AOTI packages); 134 kernel/training-path tests; 37 PT-expt trainer/descriptor/accelerated tests; 122 CPU grid/descriptor regressions; 8 GPU empty-edge regressions; and 17 precision derivative/binding checks all passed. The 30-test PT export suite also passed. Sixteen symbolic grid checks each reuse one compiled graph for edge counts 7, 9, 11, 17, 32 and 396; zero edges use one additional graph and preserve output/gradient parity. CUDA/Triton-enabled runs use all four inference/training gates set to 1, with separate gate-off controls. All pre-commit hooks passed. |

Thanks, the CUDA/export fixes and the fixed-basis variants look right, and the CI matrix is green. One blocking point on serialization, two small non-blocking ones inline.
Blocking: RadialBasis drops apply_envelope from its serialized dict without a @version bump or a legacy mapping (see inline). Released v3.2.0 DPA4C models carry exponent: 5, apply_envelope: false, and at this HEAD they reload with the envelope applied, silently.
Non-blocking, in the body since the lines are spread over three files: the new @pytest.mark.parametrize lines for env_exp (source/tests/pt_expt/descriptor/test_dpa4_accelerated.py, source/tests/pt_expt/model/test_dpa4_export.py) and options (test_empty_edge_grid_paths in source/tests/pt_expt/descriptor/test_dpa4.py) are missing the trailing comment that the pt_expt tests use to explain the parameter.

This is a silent behaviour change for existing serialized DPA4C models. On master, DescrptDPA4C built its basis with exponent=5, apply_envelope=False, so every serialized dict (including the v3.2.0 release) contains {"exponent": 5, "apply_envelope": false}. This deserialize now ignores the key and constructs C3CutoffEnvelope(exponent=5), and call() multiplies it in. @version is still 1 and check_version_compatibility(version, 1, 1) is unchanged, so nothing raises.
Reproduced with a RadialBasis(rcut=6, n_radial=4, exponent=5, apply_envelope=False) serialized on master and reloaded here, evaluated at r = 5.9:

Please bump @version to 2 and, when version == 1, map config.get("apply_envelope", True) is False to exponent=0 before constructing the object. Same treatment in any other backend that reads this dict.

The new method landed between the existing @torch.jit.export and get_type_map, so the decorator now applies to adam_route_patterns and get_type_map lost it. Scripting still works (I checked with an se_e2_a spin model: torch.jit.script succeeds and get_type_map is still callable because the exported get_ntypes reaches it), so this is not a functional break, but the intent is clearly the other way round: nothing in TorchScript needs adam_route_patterns, and get_type_map is what the C++ side calls by name. Please move the decorator back. Note that the spin TorchScript test in test_sezm_spin_model.py mocks torch.jit.script, so it would not have caught a real scripting failure here.

The current head is much improved and the CUDA/empty-edge/fixed-basis coverage looks substantial, but I still see one release-compatibility blocker.
RadialBasis.serialize() removes apply_envelope, while deserialize() still accepts @version == 1 and ignores the legacy field. A v1 DPA4C radial dict produced by released code can contain exponent > 0 together with apply_envelope: false; this head reloads it with an active envelope and silently changes predictions. If old serialized descriptor dictionaries are intentionally unsupported, the format version must be bumped so they fail explicitly. If v1 remains accepted, map legacy apply_envelope: false to exponent=0 before construction. Silently accepting v1 while changing its meaning is the unsafe option.
Non-blocking: the @torch.jit.export immediately before the newly inserted adam_route_patterns in spin_model.py now decorates that method instead of get_type_map; please restore the decorator to the intended public method.
All current checks I inspected are green, including CUDA, so this is a compatibility/API issue rather than a CI failure.

This still accepts legacy @version == 1 data but drops the meaning of apply_envelope=False. Released DPA4C v1 dictionaries can therefore deserialize successfully with a different radial function. Please either (a) preserve v1 semantics by translating apply_envelope=False to exponent=0, with a regression using a legacy serialized dict, or (b) bump the format version and reject old data explicitly.

Non-blocking: this insertion moved the existing @torch.jit.export onto adam_route_patterns(), leaving get_type_map() undecorated. Please move the decorator back to the intended externally exposed method and keep optimizer routing as a normal Python method unless TorchScript truly needs it.
Add fixed radial-basis options and single-envelope DPA4 configurations, with preset-aware JSON Schema validation and completion. Edge-free SeZM frames follow the same descriptor computation as frames with neighbors, and CUDA export metadata matches runtime output layouts.

bessel/fixandgaussian/fixin DPA4 and DPA4C. The fixed variants retain the checkpoint parameter names and shapes while excluding the basis frequencies or centers from optimization. Add thev20260911model presets.Accept an integer DPA4
env_expto apply only the message-passing cutoff envelope. Keep PT, dpmodel, PT-expt and the fused CUDA radial operator aligned, including gradients.Let descriptors declare the radial-input matrices that HybridMuon routes to AdamW. Both trainers collect these declarations without requiring parameter renames or input-file options.
Run the radial embedding, environment seed and interaction blocks for edge-free frames, preserving the isolated-atom cutoff limit. Handle empty edge sets in the Triton radial-mixing reference.
Avoid caching trace-bound FakeTensors in the CUDA radial and Wigner helpers. Express the scalar SO(3) readout as a weighted product/reduction so symbolic export does not require an einsum contraction-path search.
Match the grid-product and geometric-embedding fake output layouts to the contiguous CUDA allocations. This prevents AOTInductor from using incorrect strides for non-contiguous operands; regression tests check forward and backward operator metadata against actual CUDA execution.
Generate preset-aware JSON schemas from the existing argument definitions and preset registry. Editors accept partial overrides, suggest preset names and model-specific fields, and retain type checking. Multi-task schemas recognize inherited and per-branch presets.
