# Provenance (Sources)

The `sources` front‑matter field records the origin of a document. It is a list of identifiers (typically file names or URLs) that point to the original material used to create the concept.

## Usage

```yaml
sources:
  - SPEC.md
  - https://example.com/related-spec
```

Including sources ensures traceability, enables impact analysis when source material changes, and supports proper attribution.
