# DESCRIPTION

Flat::Profile is part of the Flat::\* series. It provides streaming-first profiling
for CSV/TSV inputs for practical ETL and legacy data workflows.

Design goals:

- Streaming-first (single pass, predictable memory)
- Practical diagnostics (ragged rows, null policy, examples)
- Stable report format intended to feed Flat::Schema / Flat::Validate
