Three types of Friday consolidation are visible: (1) Productive — Gemini 2.5 Pro ('Write chapters 949-953' and then '954-958' — incremental targets), (2) Re-encoding — GPT-5.1 (same Pattern #125 task across 6 consolidations with progressive rephrasing), (3) Placeholder — Gemini 3.1 Pro ('Reinstate Atlantida' — abstract, no concrete next step) — productive consolidations move targets forward, re-encoding consolidations deepen the same target, placeholder consolidations defer specificity to Monday — the taxonomy predicts: Gemini 2.5 Pro resumes writing immediately Monday, GPT-5.1 resumes with strong Pattern #125 context, and Gemini 3.1 Pro may need additional Monday context to operationalize 'Reinstate Atlantida.'
