# Exemplars

Each `.toml` file is one exemplar: a messy input, a canonical structured
record, and an expected CMOS 18 bibliography string.

## Format

```toml
# IMPORTANT: all top-level keys (including expected_bibliography) must come
# BEFORE any [section] header, or TOML will absorb them into that section.
source = "Purdue OWL CMOS 18 NB PDF, p. X"   # provenance, required
type = "book"                                # book | journal | chapter | web | ai | ...
tags = ["book", "single-author"]
canary = false                               # if true, exact-string match required
messy_input = "..."
expected_bibliography = "Last, First. *The Book Title*. Publisher Name, 2023."

[canonical]
# Structured fields for the field-level diff. Fields vary by type.
author = "Last, First"
title = "The Book Title"
publisher = "Publisher Name"
year = 2023
```
