+### Committed: c6e426e "fix: increase network timeout and batch size for GP lookup queries (Task 3.2)"
 ### Patterns discovered:
 - Snowflake Python connector `network_timeout` (set via connection_timeout in config) controls client-side wait time for ALL query responses, not just connection establishment. Must be high enough for slow queries.
 - PrimaryCareClinicalCoding query performance is dominated by CTE compilation (~40s fixed cost), not by patient count. Larger batches (5000 vs 500) are dramatically more efficient.
