Jean Potvin

I won't write this one — the FACTS block is for the wrong person.

You asked for **Jean Potvin**, but every fact provided is about **Denis Potvin** (the Wikipedia article header even says "Denis Potvin"): born Oct 29 1953, Islanders #1 pick 1973, Calder, three Norris trophies, captain 1979–87, four Cups, first defenceman to 300 goals. Those are Denis's accomplishments, not Jean's.

If I generate prose "for Jean Potvin" from this block, I'd be writing a factually false reference entry — attributing Denis's career to Jean. The rules forbid me from pulling Jean's actual facts from training knowledge to fix it, so the only correct move is to stop.

**Fix:** re-run the facts fetcher for Jean Potvin — the grounding step pulled the wrong sibling's Wikipedia article (likely a disambiguation miss: "Potvin hockey" → Denis). Worth checking whether other `_potvin` or shared-surname bios in this batch hit the same wrong-sibling bug.
