The 70% news bloc is recency+velocity+source+keyword, not recency+velocity alone (which sum to 0.50). Log4Shell surfaces as CWE-502 (first CNA problemType, per TestCVEListParsesLog4Shell), not CWE-20. Also reword the 04-CHALLENGES weight aside to match.
Five teaching docs (overview, concepts, architecture, implementation, challenges) grounded in real incidents (Log4Shell CVE-2021-44228, Citrix Bleed 2 CVE-2025-5777, Equifax CVE-2017-5638, MOVEit CVE-2023-34362). ASCII pipeline + data-model diagrams, a code walkthrough by function name (no line numbers), and challenges from adding a source to replacing clustering with LSH. No em dashes, per the repo's docs style.
