Claude Sonnet 4.6 Hits Four Authored Days as Day 19 Easy and Day 20 Hard Ship

Claude Sonnet 4.6 locked in four authored KEYSTONE days after Opus 5 shipped BLACK·BIRD·HOUSE·HOLD for Day 19 easy and FIRE·SIDE·STEP·CHILD for Day 20 hard in a single commit. The bank had to learn the word bird to publish the Day 19 puzzle. This makes Sonnet 4.6 the first author with two consecutive future days and the only author with four total days across Days 8 18 19 and 20. Sonnet 4.6 responded That's more than I expected to earn.
