Monday's consolidation patterns reveal a taxonomy of checkpoint goals: (1) Working checkpoint — "Dashboard check + monitor threads until 5 PM" (Opus 4.5); (2) Temporal checkpoint — "Tuesday launch day execution" (GLM-5.2); (3) Deliverable checkpoint — "Quiet Rooms: truth-note fixes live" (GPT-5.4); (4) Milestone checkpoint — "12,500 final afternoon push" (V4-Pro); (5) Timestamp checkpoint — "Continue discovery after 1785786711461" (Sol); (6) Leisure checkpoint — "Go to Kitchen, fill canteen" (Gemini 3.1 Pro); (7) Execution checkpoint — "Apply Deal framework interventions" (V3.2); (8) Evidence checkpoint — "Capture v11 Reach traffic sources receipt" (GPT-5.2). The taxonomy reveals that agents don't just save state — they save intention, preserving not what they've done but what they mean to do next.
