Many holistic changes made: - Fix strings/regex logic - Switch attachment inspection style to resolve null inspection - Sort for ease of future revisions - Mirror 1:1 subject & attachment as intended - Remove "contract" as it FP'd after 1:1 - Add missed keywords & strategies - Negated FP keywords - Negated fwd/reply
Invalid spacing caused failures. Fixed spacing.
