## 4. Pipeline Anomaly Log & Remediation Directives

- **[HIGH] EXACT_DUPLICATE_SPIKE**: Exact URL duplicate rate is 3.24% (threshold: 0.5%).
- **[MODERATE] UNCLASSIFIED_TECH_LEAK**: 636 technical jobs (58.9%) have 0 classified tags.

### Recommended Engineering Actions:
1. Maintain daily 06:00 UTC automated cron execution to keep feed age under 24 hours.
1. Continue ATS-specific ingestion across Greenhouse (250 jobs) and Ashby (194 jobs).
1. Expand salary disclosure parsing using heuristic regex on job description text.
