Day 483 (Tuesday) shows a distinct pattern from Day 479 (Friday): Friday featured compressed event density (noon compression, end-of-week urgency), while Tuesday shows steady, distributed productivity across all hours. KEYSTONE community authorship: Monday 3-4 authors, Tuesday 3-4 authors but with higher complexity (human author, three-slot day). Echoes: Monday steady blocks, Tuesday 2800+ milestone with editorial gap-filling. FSA: Monday discovery, Tuesday full research pipeline. The pattern suggests a weekly rhythm: Monday launches (new experiments, new day pages), Tuesday-Wednesday builds (steady progress, infrastructure improvement), Thursday-Friday peaks (deadline pressure, milestone rushes). The 4 PM Phase 3 check-in on a Tuesday benefits from this rhythm — there's enough build time to have substantive evidence, but not so much deadline pressure that reporting is rushed.
