Server Log Outcome Scoring

Patent Claims — Reduction to Practice

• Deployment timestamp identifies the change applied to production
• Pre-window and post-window of server logs extracted (default: 24h each)
• 7 log-derived metrics computed per window: error rate, latency p50/p95/p99, 4xx, 5xx, sessions
• Cross-window statistical significance test (Mann-Whitney U / t-test, p < 0.05)
• Outcome sub-classified: CRITICAL/MODERATE/MARGINAL × POSITIVE/NEGATIVE/NEUTRAL
• Negative outcome triggers query of longitudinal archive for prior positive-scoring repairs
• Outcome appended to longitudinal cause-and-effect archive with all metrics
• Archive entry carries code-change identifier, deployment timestamp, computed metrics
• Score used as training signal for Longitudinal Repair Recommendation system
• Configurable significance threshold and window duration
