K-correction bug (report.js):
calculateTScore used this.scores["K"] (the K T-score) for
K-correction, but standard MMPI-2 scoring uses the K raw score.
The T-score tables are indexed by K-raw-corrected values -- using
K T-scores produces inflated indices that clamp to 120 for most
moderate-to-high score combinations.
T-score data fixes (scales.json):
Mf male: 666 -> 66 (extra digit in +2 stride)
PK female: 87389 -> 87,89 (two values concatenated; array was 1 short)
NEGE female: 81384 -> 81,84 (same concatenation issue)
Sc male: 4 -> 41 (truncated digit; matches female Sc pattern)
AAS female: 7 -> 73 (truncated digit; fits repeating 5,6,6 diff cycle)
Pt male: 93 -> 83 (typo; +2 stride: 79,81,83,85)
Ma male: 59 -> 69 (copy error from nearby value; single digit typo)
Sc4 female: 40 -> 70 (truncated leading 7; +5 stride)
Mt male: 30 -> 90, 31 -> 91 (leading 9 dropped from both)
ASP female: 42 -> 52 (best fit interpolation, verified against manual)
A female: 76 -> 78 (preserves +1,+1,+1,+2 cycle, verified against manual)
Item assignment fixes (scales.json):
D1: [223,true] -> [233,true] (q223 is non-depressive when true;
single digit typo, q233 already in parent D scale as true;
verified against Graham 1993 Appendix C)
Es: [325,true] -> [323,true] (verified against Graham 1993 Appendix J)
GF: [475,true] -> [473,true] (verified against Graham 1993 Appendix J)

Summary
calculateTScoreusesthis.scores["K"](the K T-score) but standard MMPI-2 K-correction uses the K raw score. The T-score arrays are sized for K-raw-corrected indices -- using K T-scores produces inflated values that silently clamp to 120.scales.json: truncated digits, concatenated values, transposed digits, dropped leading digits. All identified via monotonicity checks and verified against published norms.scales.json: D1 had q223 in both true and false lists (should be q233 in true), Es had q325 (should be q323), GF had q475 (should be q473). Verified against Graham (1993) appendices.See commit message for per-fix details.
