Behavior Notes

• The same seed, settings, and data files will produce the same result.
• List generation uses seed + index.
• Bust weights accept raw values in the 0.00 to 1.00 range and are normalized internally.
• include_base_prompt = false omits the base prompt from generated output.
• If include_base_prompt = true and base_prompt is empty, the default base prompt is used.
• If all bust weights are 0, generation falls back to the Balanced preset distribution.
• fixed_bust_size overrides weighted bust selection.
• fixed_accessory overrides accessory probability when a concrete accessory is selected.
• fixed_accessory = none means no fixed accessory in the node UI.
• The special forced-no-accessory state is supported through saved settings_json data from the web integration.
• production_mode = true hides entries marked with developmentOnly: true.
