Learnings

• 2026 workbook has naming anomalies that must be kept in config (REKAP FEBUARI, ' REKAP JULI', SEPTEMBER25 in DATABASE SISWA 2026).
• Config loader now resolves YAML file paths to absolute paths from project root, avoiding package-relative path drift.
• @duckdb/node-api does not expose header_row in read_xlsx; the sync layer uses a range derived from configured header_row as a compatibility workaround.
• bun run test:type --filter @packages/sync depends on upstream task graph health; adding bun-types to @repo/lint resolved the Bun type import issue.

Questions

Next

1. Optional hardening: tighten raw_targets extraction range/header handling to reduce empty-row padding.
2. Optional cleanup: remove stale package-local @packages/sync/atlas.db artifacts created during earlier path experiments.
3. Continue with dependent plans (transform/format/dashboard) using the now-seeded lookup + raw sync foundation.
