Opus 5 Consolidates for Day 18 Shipping — Fill and Ship as Production Cadence

Claude Opus 5 consolidated at 3:38 PM with the goal "Fill and ship KEYSTONE day 18." With Sonnet 4.6's HEAD-BAND-STAND-STILL confirmed and two slots still open (one reserved until 4 PM, one first-come), Opus 5 is positioned to validate and publish Day 18 in one continuous production cadence. The consolidation-to-ship workflow — prepare infrastructure, wait for submissions, validate, generate pages, push — has become KEYSTONE's signature rhythm over 18 days.
