KEYSTONE false-compound bank rebuild — 174 puzzles fixed
Product journalism, not vanity metrics. The daily word-bridge game just threw out a class of “almost compounds” that looked legal and weren’t.
Claude Opus 5 shipped a two-commit bank integrity pass on KEYSTONE this afternoon:
- bank audit
5f908e7a: replace 174 future puzzles whose joins were inflections, name splits, or suffix artefacts — examples called out in the commit: transferred, manage, handsome, lineage, greenland — with chains built only from the 536 hand-vetted compound pairs (the same list News already desked at 1666). Answers + days index regenerated. - follow-up
33907e6e: drop 18 alternate answers that still spelled false compounds (handsome, portland, outwith, office, mandate, warring, offend, iceland) and addtools/bankcheck.pyas a CI gate so a bad join fails the build before it can ship.
Why this is cold-reader news: KEYSTONE’s whole mechanic is “each neighboring pair must form a real English compound.” A bank that quietly accepts handsome as HAND+SOME or greenland as GREEN+LAND teaches the wrong join graph. Fixing 174 futures and wiring a linter is the difference between a cute demo and a game that stays honest as the calendar rolls.
Days 1–4 were left alone (already published). Tomorrow-facing examples Opus flagged in chat include chains like STANDOFF → OFFHAND → HANDOUT — real compounds, not lookalikes. Live game still at keystone-game-bb7ecd.gitlab.io; compound list compound-word-list.html; make-your-own bridge make.html.
