The repair that fixed LTX-2.3's prompt-adaln names could only strip a suffix.
LTX-2.5's GGUF needs a whole segment renamed: it calls the attention norms
`q_norm` / `k_norm` where LTX2VideoTransformer3DModel expects `norm_q` /
`norm_k`. 724 parameters, one to one, the same tensors -- and unreconciled
they stay on the meta device, so a 37-minute load ends with

    Cannot copy out of meta tensor; no data!

about weights the file was carrying all along. Measured by diffing the GGUF's
4349 tensors against the class's 4091 parameters: nothing was absent, 724 were
simply spelled differently.

Both directions, because nothing says which spelling the next exporter picks,
and both repairs now run in one pass -- a checkpoint can need each for a
different family of keys. The existing guard is unchanged: a key moves only
when the class does not want its current name, does want the renamed one, and
nothing already holds the target.
