# Task 4: ClickHouse CLAUDE.md Alignment

Investigate and verify that `/python/opendeviationbar/clickhouse/CLAUDE.md` (14KB) matches actual cache implementation. Create scaffolding directory at `/tmp/crew-clickhouse/`. Check `schema.sql` matches documented columns; verify `populate_cache_resumable()` signature and behavior; validate ClickHouse connection code matches documented approach; confirm dedup hardening procedures are documented. Use Dynamic Task Creation: if schema or API mismatches found, create sub-task to reconcile. Broadcast key findings to all peers.
