# Coverage Map (Section Tracking)

This directory tracks coverage by **section**, not by raw rule count.

We do not store OCR text. Entries reference sections and pointers only.

## Files

- `cmos18_sections.json`
- `bring_sections.json`

## Schema (per file)

```json
{
  "book": "CMOS18",
  "source": "The Chicago Manual of Style, 18th ed (OCR)",
  "updated_utc": "YYYY-MM-DDTHH:MM:SSZ",
  "sections": [
    {
      "section_id": "§1",
      "title": "Section title",
      "pointer": "CMOS18 §1 p1",
      "status": "uncovered",
      "rule_ids": []
    }
  ]
}
```

## Status values

- `uncovered`: no rules mapped yet.
- `partial`: some rules mapped, section not fully covered.
- `covered`: all rule-bearing guidance mapped into paraphrased rules.
- `out_of_scope`: narrative or non-prescriptive section.

## Rules of engagement

- Paraphrase only. Never include book text.
- Use precise pointers in `source_refs`.
- If exact wording is required: `Exact wording required—refer to pointer`.
