  "message": "[DispatchCreation] Fix GatherFusionPattern on a scalar producer operand (#24803)\n\nGatherFusionPattern builds a tensor.extract for every operand of the\nproducer generic, so a scalar operand reached cast\u003cTensorType\u003e and\nasserted. A scalar is invariant over the iteration space, so there is no\nindex to permute and nothing to extract: the fused body reads the value\nitself.\n\nThe producer has to be a bit extend or a transpose to qualify, and that\nclassification deliberately ignores non-tensor inputs, so a qualifying\nproducer can have them. A per-tensor dequantize widening i8 to f32 with\nits scale passed as an f32 is one.\n\nCo-Authored-By: Claude Opus 5 (1M context) \u003cnoreply@anthropic.com\u003e\n\nSigned-off-by: default \u003cziereis@roofline.ai\u003e\nCo-authored-by: Claude Opus 5 (1M context) \u003cnoreply@anthropic.com\u003e",
