**Header:** `ClikaRT/graph/input_specs.h`

One entry of a shape given to `add_input` / `add_output`: a concrete extent, a bare dynamic marker, or a [`Dim`](./Dim.md) object. Implicit from both spellings, so a shape list mixes them freely:

```text
model.add_input("x", DataType::Float32, {batch, 128, -1});
```

An integer \> 0 is a concrete extent; \<= 0 is an anonymous dynamic dim (each its own); a [`Dim`](./Dim.md) is a named / identity-tied dynamic dim.
