Appendix — FAQ

Why does LedgerLoom exist?

LedgerLoom is a MIT-licensed reference implementation that demonstrates how to model accounting data as a canonical event log (entries + postings) and produce reproducible financial reports.

Is LedgerLoom a replacement for accounting software?

No. LedgerLoom is designed as a learning and prototyping tool. It is intentionally small, readable, and deterministic.

What is the difference between the “chapter runners” and the core library?

• The core library (ledgerloom.core / ledgerloom.reports) is reusable code.

• The chapter runners (ledgerloom.chapters.*) are demos that generate artifacts used in the documentation.

Where are the outputs written?

By default, chapter runners write to outputs/ledgerloom/. Each chapter writes to its own subfolder (e.g., outputs/ledgerloom/ch02).
