[nitpick] Adding a brief comment clarifying that -1 is used as a sentinel for dynamic dimensions would help maintainers understand the control flow.

Suggested change

for (size_t i = 0; i < shape.size(); ++i) {
// -1 is used as a sentinel value for dynamic dimensions, allowing any positive size to match.

[nitpick] Consider replacing the magic number -1 with a named constant (e.g., kDynamicDimension) to improve code readability and maintainability.

Suggested change
expected_.push_back(-1);
expected_.push_back(kDynamicDimension);
