A delta that does not fit its target module cannot apply, and applying only
the layers that do fit leaves the model in a state nothing was trained for,
so try_load_chain drops the whole file when any family reports a mismatch.
Bias deltas were never checked against the target bias and could only surface
at apply time; a module with no bias stays a non-mismatch, since whole
architectures are built bias=False.
- check bias deltas against the module bias in the lora, norm and full loaders
- carry the mismatch count on the network so the chain can refuse the file
- record refused writes in the infotext so a partial apply is not read as clean
- point the krea2 full-diff test at a module that has a bias
The Krea 2 transformer keeps checkpoint-style module names while the
official krea/Krea-2-LoRA releases are saved with upstream-diffusers
names, so all 264 modules failed to bind and the LoRAs silently did
nothing. Krea 2 is the only native-LoRA arch with an sdnext-owned
transformer, so its module names diverge from the diffusers ecosystem.
- native_adapter.resolve_group_targets consults the arch resolver first
for passthrough prefixes, falling back to verbatim binding; a no-op
for arches that load the diffusers class
- krea2_lora maps diffusers attn/ff/text_fusion/embedder names onto the
checkpoint module tree; checkpoint-named LoRAs still bind verbatim
- add test/test-krea2-native-adapters.py
