What
When a command fails with the error_during_execution result, the CLI now prints an extra line to stderr (the terminal's error output) before the existing generic 'Execution error' message, if one was recorded. This new line explains that automatic mode is unavailable.
Why
Previously a failure in this case only showed the generic 'Execution error' text, giving no clue as to the specific cause. The added notice gives a more specific reason for the stop, making it easier to understand why execution halted.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say what triggers the 'automatic mode unavailable' condition or what 'auto mode' refers to.
