🚨 Severity: MEDIUM
💡 Vulnerability: Missing input validation for numeric parameters used in statistical distributions
🎯 Impact: Malicious or malformed conf.level values could cause qnorm() to fail ungracefully, return unexpected NA/NaN structures, or lead to Denial of Service via resource exhaustion on invalid intervals
🔧 Fix: Added rigorous type, length, and range checking (0 < conf.level < 1) for the conf.level parameter.
✅ Verification: Ran test suite

icci는 모델 비교 전에 conf.level을 검증합니다. 유효하지 않은 값이면 지정된 오류 메시지와 함께 실행을 중단합니다.

icci conf.level 검증

Layer / File(s) Summary
conf.level 사전 검증
R/icci.R
icci는 conf.level이 길이 1인 숫자형 값인지 확인합니다. NA, 0 이하 또는 1 이상인 값이면 "conf.level must be a numeric scalar strictly between 0 and 1" 오류를 발생시킵니다.

exact-head review @ a21d487ddeb7e0d5af4e3957d6da5de7f8348897

fresh protected-base fetch에서 이 exact head의 effective diff가 현재 0입니다. 따라서 이 head 자체를 icci(conf.level) security/input-validation fix로 merge할 semantic delta가 없습니다. 다만 PR0 규칙상 이를 곧바로 duplicate Close로 처리해서도 안 됩니다.

canonical Draft #126 exact 5a4be4cc5e231dc14155b611b4396ec631d5083a가 동일 exported boundary를 이미 소유하고 있고, numeric(0), non-scalar, NA/NaN/±Inf, wrong type, 0/1 및 out-of-domain을 실제 icci() admission boundary에서 검증하며 stable message + conditionCall()==NULL까지 고정합니다. #126은 이 계약을 MEDIUM DoS/정보노출로 승격하지 않고 deterministic input/error handling으로 doctoring하고 있습니다.

Acceptance:

  • #147의 historical non-empty commits에서 source/test/fixture/evidence를 exact diff로 다시 읽고, 유효 delta가 #126 current exact에 모두 존재하는지 증명합니다.
  • 완전 승계가 확인되면 verified-successor PR0 경로로 정리하되 predecessor GREEN/review는 전이하지 않습니다.
  • unique valid regression이나 contract가 하나라도 남아 있으면 #126에 ordinary/non-force로 승계한 뒤 그 successor exact head에서 새 GREEN을 받습니다.
  • conf.level 오입력이 실제 resource-exhaustion DoS가 된다는 deployed threat/witness가 없으므로 MEDIUM DoS 서술은 승계 대상 evidence로 간주하지 않습니다.

현재 판정: effective product delta 0 / canonical successor 존재 / complete-succession verification 필요 / independent merge authority 없음.
