Mods -> MSCO mod list: search the approved mods from msco.mbm.wtf/mods and add or update one with a click. The server lists and downloads only from the official keymaster (never from a URL in the answer), checks the SHA-256 and stores it in data/mods like an uploaded mod. Admins only. 6 new tests (154 pass). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
