Learnings

• best_year was implemented per-unit for the same month across years.
• Report and section types are exported from @packages/format/@source/index.ts for downstream consumers.
• bun run --filter executes in package context, so DB paths should be resolved from project root.
• duckdb-async was unstable under Bun in this flow; @duckdb/node-api is stable in-repo.

Questions

• None yet

Next

1. Use output/monthly/2026-02-report.json as the handoff input for Plan 006 (Present layer).
2. Keep @packages/format bindings on @duckdb/node-api unless Bun runtime compatibility changes.
