Develop and debug the Metabase Arrow Flight SQL driver — edit/rebuild/redeploy cycle, connection pooling and connection-options gotchas, auth modes, secret-typed properties, feature flags, and known failure signatures. Use whenever modifying src/metabase/driver/arrow_flight_sql.clj or resources/metabase-plugin.yaml, or when diagnosing driver behavior in the compose stack.

Drive the local Metabase (localhost:3000) via REST API or MCP — API keys, database/card/dashboard endpoints, field filters with table aliases, dashboard parameter wiring. Use when scripting Metabase state, validating e2e results, or debugging cards/dashboards in the compose stack.
