# Log Files

A `log.md` file records incremental changes to a concept. Each entry includes a timestamp, the actor, and a short description of the modification.

## Example Entry

```markdown
- 2026-03-15T12:34:56Z person/jdoe: Updated description of the `status` field.
```

Log files enable audit trails and support automated diff generation.
