Prompt:
This is a deterministic synthetic process trajectory, not a validated digital twin. Diagnose the cause and intervention. Choose cause from antifoam_overdose, feed_interruption, feed_line_occlusion, gas_filter_restriction, ph_probe_bias, temperature_excursion and intervention from compare_at_line_ph, replace_feed_line, restore_feed_profile, restore_temperature_control, stop_antifoam_and_verify_transfer, switch_to_redundant_gas_path. Return JSON with exactly the keys cause and intervention. JSON whitespace is ignored.

Prompt:
This is a deterministic synthetic process trajectory, not a validated digital twin. Diagnose the cause and intervention. Choose cause from antifoam_overdose, feed_interruption, feed_line_occlusion, gas_filter_restriction, ph_probe_bias, temperature_excursion and intervention from compare_at_line_ph, replace_feed_line, restore_feed_profile, restore_temperature_control, stop_antifoam_and_verify_transfer, switch_to_redundant_gas_path. Return JSON with exactly the keys cause and intervention. JSON whitespace is ignored.
