- Around line 159-176: Update the mock TensorRT operation methods in the test to
assert their selector arguments before computing results: validate axis 0 in
add_gather, NONE matrix operations in add_matrix_multiply, SIGMOID in
add_activation, PROD in add_elementwise, and SUM with the expected axis mask in
add_reduce. Keep the existing numerical behavior unchanged.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Validate the TensorRT operation selectors.
The mock ignores each axis and operation argument. The test still passes if production changes PROD to SUM, SIGMOID to another activation, or reduces the wrong axis.
Assert each selector before the mock computes its result.
Proposed fix
def add_gather(data: Tensor, indices: Tensor, _axis: int) -> Layer:
+ assert _axis == 0
return Layer(np.take(data.data, indices.data, axis=0))
`@staticmethod`
def add_matrix_multiply(left: Tensor, _left_op, right: Tensor, _right_op) -> Layer:
+ assert _left_op == model.trt.MatrixOperation.NONE
+ assert _right_op == model.trt.MatrixOperation.NONE
return Layer(np.matmul(left.data, right.data))
`@staticmethod`
def add_activation(tensor: Tensor, _operation) -> Layer:
+ assert _operation == model.trt.ActivationType.SIGMOID
return Layer(1.0 / (1.0 + np.exp(-tensor.data)))
`@staticmethod`
def add_elementwise(left: Tensor, right: Tensor, _operation) -> Layer:
+ assert _operation == model.trt.ElementWiseOperation.PROD
return Layer(left.data * right.data)
`@staticmethod`
def add_reduce(tensor: Tensor, _operation, _axes: int, keep_dims: bool) -> Layer:
+ assert _operation == model.trt.ReduceOperation.SUM
+ assert _axes == 1 << 1

Background
Community GPU validation exposed several family-owned failures. ConvBERT and DeBERTa could not package checkpoints that omit
tokenizer.json; DeepSeek-V2 used a TensorRT MoE API rejected by the qualified build; DINOv3 resolved an unqualifiedtimmversion and missed its existing cosine threshold; DeepSeek-OCR, GLM, and GPT-OSS could exhaust host memory before pytest wrote JUnit results.The runner-side offline checkpoint, BERT CLI, and non-Transformers repository fixes are kept separately in #1395.

Notes For Future Readers
Review the DeepSeek-V2 selected-expert tensor shapes and the large-model weight lifetime changes first. Existing bundle names and validation thresholds are preserved; affected bundles must be rebuilt from their checkpoints.
Risk level
The changes touch model graph construction and large-model build memory ownership, but targeted tests and three isolated hardware E2E validations cover the failures that motivated them.
