That makes the wavelength array non-monotonic (`[real_min, …, real_max, 0, 0, …, 0]`). `LatentSpectralGrid.to_latent` feeds it to `interp1d`, whose out-of-range mask is `(xnew < x[..., 0]) | (xnew > x[..., -1])`. With `x[..., -1] == 0`, every latent grid position satisfies `xnew > 0` and the whole latent representation is replaced with `mask_value = 0.0`. Every spectrum then encodes to (essentially) the same null embedding. This shows up in downstream consumers that call the spectrum codec on inputs whose length is less than `pad_length` (so `F.pad` actually appends elements). Switching the dict key to `"wavelength"` so it matches the attribute name fixes the sentinel.
