Single model line workflow: AutoTuner → Optimizer. Only one node
merges at a time — the other is passthrough. A JS bridge syncs
the two switches as opposites when tuner_data is connected.
LoRAOptimizer:
- Add settings_source (manual/from_autotuner) and tuner_data inputs
- New execute_node entry point: from_autotuner = passthrough with
widget sync via UI data, manual = normal merge
- Subclass safety: LoRAOptimizerSimple and WanVideoLoRAOptimizer
explicitly set FUNCTION="optimize_merge" to bypass bridge
LoRAAutoTuner:
- Add output_mode (merge/tuning_only): tuning_only skips final
merge and returns base model unchanged while still outputting
scored tuner_data for downstream use
- Fix pre-existing bug: two error paths returning 5-element tuples
instead of required 6
JS (new lora_optimizer_bridge.js):
- onExecuted: sync Optimizer widgets from applied_settings
- Opposing switch sync with recursion guard:
from_autotuner ↔ merge, manual ↔ tuning_only
