The duckdb library is already gone (not a dependency, not importable, no `import duckdb` anywhere) — these were leftover text references that misled. - Delete storage/schema.py: 418 lines of DuckDB DDL with zero importers. The Postgres schema is created by db_pg._apply_schema + event_store._ensure_schema. - Neutralise stale default db_path strings (./data/momentum*.duckdb) in event_store, config, run_live_paper, dashboard_api — the connection layer ignores the path (DATABASE_URL is the datastore), so these phantom file paths only created confusion. Dropped the now-pointless os.makedirs for them. - research/multi_schema: the "three DuckDB files" are one Postgres DB now (all resolve to the same connection); doc + constants updated to match reality. - Fix stale "DuckDB handle" comments in api/main. Kept the DuckDB mentions in storage/db_pg.py + storage/db.py — they document why the Postgres facade mimics DuckDB's ? placeholders and :memory: semantics.
