Set the autonomy ranges to hint 0-10, assist 15-25, pair 30-50, copilot
55-85, and auto 90-100 in the skill and the template level line, and
refill the example accordingly.
Sharpen the stage criteria where trial runs disagreed: grade design by
who supplied the adopted structure, count only the author in the first
four stages, ignore process and ordering instructions, define the main
change, keep review at n/a until a comment is handled, and separate
copilot from pair by whether every non-wording item got a human
response. Clarify the Changes categories, test evidence, disclosure
placement, language, and when to update the description.
