New principle 30, "Overcorrection Is Agreeableness Amplified", in section VIII (Configuration Lifecycle) as the counterweight to 29: most corrections are about one case and are not asking for a rule.
"Cost Is Visible, Use Isn't" and "Re-tune as the Model Improves" renumber to 31 and 32. No other text changed.
