True reset semantics for "default":
- On first selector application, cache the loader's original
load_device / offload_device on the underlying model object (which
is shared across patcher clones) and restore those base values when
the user picks "default". Previously "default" meant "passthrough"
so SelectXDevice(gpu:1) -> SelectXDevice(default) silently kept the
gpu:1 routing.
CPU + dynamic VRAM:
- When SelectModelDevice / SelectCLIPDevice resolves to CPU on a
ModelPatcherDynamic, also call clone(disable_dynamic=True) so the
result is a plain ModelPatcher, matching ModelPatcherDynamic.__new__'s
intent that CPU loads never run through the dynamic path. Fallback to
the regular dynamic clone if disable_dynamic is unsupported on that
patcher.
MultiGPU collision pruning:
- After SelectModelDevice retargets the primary patcher, drop any
multigpu clone (from a prior MultiGPU CFG Split) whose load_device
now matches the primary; otherwise two patchers would be bound to
the same device. Logs the prune at info level.
SelectVAEDevice: reject CPU at runtime:
- The UI uses get_gpu_device_options_no_cpu(), but a workflow opened
from another machine could still pass "cpu" through validate_inputs.
Detect that case explicitly, log a "CPU is not a supported choice"
passthrough message, and leave the VAE unchanged.
Cosmetic:
- Update VAE node docstring to accurately reflect the runtime CPU
rejection rather than the older "intentionally not offered" claim.
- Demote the fallback warnings inside resolve_gpu_device_option to no
log at all; the Select*Device nodes now own a single context-rich
info-level message per failed lookup, so there is no double logging.
