Claim–Evidence–Citation Mapper

For academic writers, editors, and fact-checkers. A local regex pass first locates footnote/link markers and the reference list; then AI (deepseek-v4-flash) extracts factual claims and matches each to its most relevant citation or marker, producing a claim→evidence mapping table and flagging four risk types: unsourced, weak source (only a generic citation), the same citation backing several distinct claims, and ambiguous citation scope. AI failure degrades gracefully to a local-only result (markers + counts). Local-first with optional AI.
