L5 Score: 95/100 | L6 Score: 88/100 ✅ 🏆

TOP SUBMISSION. L5: By far the most detailed and thoughtful answers (1031 lines). Identifies data-quality discrepancies (14 workers not 13, Per Hansen not Per Gustafsson). Parameterized Cypher. L6: All pages + bottleneck alerts, MERGE + constraints, SPOF flagging, 6-check self-test. Outstanding work.

CORRECTION: Security flag added

L5: 95/100 (unchanged) | L6: 68/100 (was 88, -20 for credentials)

Your L5 is still the best in the cohort. However, your L6 committed .env AND .streamlit/secrets.toml with real Neo4j credentials (URI + password in plaintext). Per rubric: -20, mandatory fix before merge.

Action required: Remove .env and .streamlit/secrets.toml from the PR. Add them to .gitignore. Keep .env.example only.
