Relational fake datasets

Generate connected test data (users, their orders, the orders' line items) with primary and foreign keys drawn from one seeded stream. Same seed, same locale, same preset: byte-identical files. CSV/JSONL per entity with a manifest, or one SQL bundle.

- Presets are the registry. No arbitrary user-defined entity graph in this round.
- Values come from the same bounded field set as the bulk test-data builder; no finance fields anywhere.
- The SQL bundle reuses the CSV-to-SQL quoting rules (TEXT columns, '' doubling) and nothing more: no schema design, no execution.
