ScoringEngine Scoring Formula

Category Scores:
  - codeQualityScore = calculateCodeQualityScore(codeQuality)
  - testCoverageScore = calculateTestCoverageScore(testCoverage)
  - architectureScore = calculateArchitectureScore(architecture)
  - securityScore = calculateSecurityScore(security)

Weighted Components:
  - codeQuality.weightedScore = codeQualityScore × weights.codeQuality (0.25)
  - testCoverage.weightedScore = testCoverageScore × weights.testCoverage (0.25)
  - architecture.weightedScore = architectureScore × weights.architecture (0.25)
  - security.weightedScore = securityScore × weights.security (0.25)

Overall Score:
  - overall = sum of all weighted scores (0-100)

Grade Assignment:
  - A: ≥90, B: 80-89, C: 70-79, D: 60-69, F: <60

Status:
  - Pass: score ≥ 80
  - Fail: score < 80

CodeQualityAnalyzer Scoring Formula

Component Scores:
  - complexityScore = 100 - (critical × 5 + warning × 2)
  - duplicationScore = 100 (if <3%), 90 (if 3-5%), 70 (if 5-10%),
                       100 - (percent - 10) × 5 (if >10%)
  - lintingScore = 100 - (errors × 10) - max((warnings - 5) × 2, 50)

Overall Score:
  - codeQualityScore = (complexityScore × 0.4) +
                       (duplicationScore × 0.35) +
                       (lintingScore × 0.25)

Thresholds:
  - Pass: ≥80
  - Warning: 70-80
  - Fail: <70

CoverageAnalyzer Scoring Formula

Coverage Calculation:
  - avgCoverage = (lines% + branches% + functions% + statements%) / 4

Effectiveness Factors:
  - Meaningful test names
  - Average assertions per test
  - Excessive mocking detection

Overall Score:
  - coverageScore = (avgCoverage × 0.6) + (effectivenessScore × 0.4)

Thresholds:
  - Pass: ≥80%
  - Warning: 60-80%
  - Fail: <60%

ArchitectureChecker Scoring Formula

Component Scores:
  - componentScore = 100 - (oversizedCount × 10)
  - dependencyScore = 100 - (circularCount × 20 + violationCount × 10)
  - patternScore = (reduxScore + hookScore + bestPracticesScore) / 3

Overall Score:
  - architectureScore = (componentScore × 0.35) +
                        (dependencyScore × 0.35) +
                        (patternScore × 0.3)

Thresholds:
  - Pass: ≥80
  - Warning: 70-80
  - Fail: <70

SecurityScanner Scoring Formula

Base Score: 100

Deductions:
  - Critical vulnerabilities: -25 points each
  - High vulnerabilities: -10 points each
  - Critical code patterns: -15 points each
  - High code patterns: -5 points each
  - Performance issues: -2 points each (capped at -20 total)

Final Score:
  - securityScore = max(0, 100 - totalDeductions)

Thresholds:
  - Pass: ≥80
  - Warning: 60-80
  - Fail: <60
