Practical tooling

This section documents LedgerLoom’s “practical tool” surface area.

The practical tool is designed for accountants, developers, and data professionals:

• Accountants get a familiar workflow (period folders, exception lists, reviewable reports).

• Developers get deterministic outputs and an auditable pipeline.

• Data pros get tidy tables suitable for analysis.
