Phase 1: Extract Footnotes

What this skill carries — grep references/ for any subject the names below miss: !d=${CLAUDE_SKILL_DIR}; command -v skill-toc >/dev/null 2>&1 && exec skill-toc "$d"; s=$HOME/.claude/skills/plugin-utils/bin/skill-toc; [ -x "$s" ] && exec "$s" "$d"; echo "(skill-toc unavailable: references and scripts are NOT listed here — install the plugin-utils plugin, or start a new session so its bin/ reaches PATH)"

Parse the DOCX file and build structured data for all subsequent phases.

What This Phase Does

1. Parse word/footnotes.xml via lxml
2. Extract each footnote's runs with formatting flags (italic, small caps, bold)
3. Parse word/_rels/footnotes.xml.rels for hyperlink URLs
4. Build citation registry (hereinafter definitions, author-to-first-cite mapping)
5. Resolve cross-references (supra note [_] placeholders)
6. Extract all URLs for archiving inventory
