A concrete starting point
Evaluate a flat sequence of boolean values joined by AND and OR with AND taking precedence. Check True OR False AND False and reject empty input, misplaced operators, parentheses or non-boolean operands without executing strings.
Define the change
Describe the input, expected output and boundaries that must stay intact.
Inspect the work
Review the proposed edits and any commands before relying on their result.
Check the outcome
Compare actual behavior with the expected result. If a check fails, investigate it before applying more changes.
