Evidence-Binder

What this Skill does

Transforms standards-core outputs (coverage.json, evidence.jsonl, pages.jsonl) into a polished, reviewer-ready document:

• Markdown binder — hierarchical standards + evidence with page anchors and quoted spans.
• PDF export — formatted, multi-page report with bookmarks and page numbers.
• DOCX export — editable Word document for reviewer markup and collaboration.

Perfect for EdReports-style curriculum reviews and evidence-based alignment audits.

How to run

1. Receive inputs from standards-core skill (or user provides paths).
2. Read coverage.json, evidence.jsonl, pages.jsonl.
3. Template-render the evidence into Markdown.
4. Convert Markdown → PDF via pandoc or weasyprint (optional).
5. Convert Markdown → DOCX via pandoc (optional).
6. Write outputs to binder/ directory.

Inputs (ask user or read from CLI)

• coverage_json: path to outputs/coverage.json
• evidence_jsonl: path to outputs/evidence.jsonl
• pages_jsonl: path to outputs/pages.jsonl
• title: e.g., "Grade 3 Math Textbook Alignment Review"
• subject: math|ela
• format: markdown|pdf|docx|all
• out_dir: binder/

Deterministic rendering

• Use Jinja2 or Handlebars template for Markdown layout.
• Organize by standard → pages → quotes.
• Include page anchors (e.g., math_grade3:12:45:92) for traceability.
• Bold or highlight uncovered standards.

Scripts to call

• scripts/render_binder.py --coverage outputs/coverage.json --evidence outputs/evidence.jsonl --pages outputs/pages.jsonl --format {markdown|pdf|docx|all} --out binder

## Uncovered Standards

The following standards lack evidence in the provided materials:

{% for standard in standards | selectattr('evidence_found', 'false') %}
- **{{ standard.id }}** (Grade {{ standard.grade }})
{% endfor %}

## Methodology Notes

This alignment review was conducted using automated standards-mapping software with manual verification of boundary cases. All evidence references include page anchors (`book_id:page:start:end`) for direct verification.

Workflow example

# Generate Markdown binder from standards-core outputs
scripts/render_binder.py \
  --coverage outputs/coverage.json \
  --evidence outputs/evidence.jsonl \
  --pages outputs/pages.jsonl \
  --title "Grade 3 Math Alignment Review" \
  --format all \
  --out binder

# Review generated files
ls -lah binder/
cat binder/alignment_report.md

Error handling

• If coverage.json is missing, halt with descriptive error.
• If evidence.jsonl is empty, generate a binder noting "No evidence compiled."
• Gracefully handle missing optional fields (e.g., redundancy_count).
• If pandoc is not available, offer Markdown-only mode and warn user.

Accessibility & reproducibility

• Include generation timestamp and standards pack version in binder footer.
• All quotes include full page anchors for verification by independent reviewers.
• Binder is self-contained; can be shared as standalone PDF or DOCX.
