Clear 100 “citation needed” tags on Wikipedia with real, reliable sources

More than 520,000 Wikipedia articles carry “citation needed” flags, and those unsourced claims get copied into essays and AI answers every day. Pick a topic you know well and do the slow, useful work: find proper sources, or remove claims that cannot be backed up.
