Phase 7: Cross-References

Convert hardcoded supra/infra note numbers to NOTEREF field codes that auto-update when footnotes are renumbered.

What This Phase Does

1. Scan footnotes for supra note N and infra note N patterns
2. Add bookmarks to target footnoteReferences in document.xml
3. Replace hardcoded numbers with NOTEREF field codes
4. Preserve existing NOTEREFs and bookmarks

Script

BB_SCRIPTS=$(${CLAUDE_PLUGIN_ROOT}/skills/bluebook-audit/scripts)

# Preview changes
python3 "$BB_SCRIPTS/create_crossrefs.py" --docx <path> --dry-run

# Apply (creates .bak backup)
python3 "$BB_SCRIPTS/create_crossrefs.py" --docx <path>

Workflow

1. Dry run first — review the cross-reference map and bookmark plan
2. Apply — the script backs up the original before writing
3. Verify in Word — open the DOCX, press Ctrl+A then F9 to update all fields
4. Spot-check — confirm 5-10 supra references display the correct numbers
5. Renumber test (optional) — add a footnote before a referenced target and confirm the supra numbers update

What Gets Converted

What Is NOT Converted (Phase 2 — Future)

• Part/Section references (supra Section I.A., infra Part III)
• These require a heading-to-bookmark mapping strategy since heading numbering is partially auto-generated

Gate: Exit Cross-References

• Dry run reviewed — cross-reference map is correct
• NOTEREF fields created for all supra/infra note references
• Backup DOCX exists
• Word field update (Ctrl+A, F9) confirms correct numbers

Workflow Complete

Present final summary to user:

• Total formatting corrections applied (from Phase 4)
• Total URLs archived (from Phase 6)
• Total NOTEREF fields created (from Phase 7)
• Final DOCX file path
