SYNTHETIC EDITORIAL KEY. THEME CODING IS NOT A CAPTURED MODEL RESULT. Input 10; nonblank 9; blank 1 (R07). Navigation: R01 R04 R06 => 3/9 = 33.3%. Export issue/request: R02 R03 R06 R08 => 4/9 = 44.4%. Price concern: R10 => 1/9 = 11.1%. No improvement theme: R05 R09 => 2/9 = 22.2%. R08 reported resolved. R03 feature request, not broken export. R10 praises export while objecting to price. R06 counts once in each of two themes. Nine answered respondents yield ten category assignments. Percentages may exceed 100% when summed because theme membership overlaps. Binary matrix in approved-codes.csv. This is a defined exercise key, not proof of general coding objectivity or customer prevalence.
