  "summary": "A packed calendar can be evidence of planning or evidence that planning lost the plot.",
  "kind": "checklist",
  "body": "Research defines time management more broadly than scheduling: structuring, protecting and adapting time. A large meta-analysis links time management with performance and wellbeing, while randomized evidence supports progress monitoring as a goal-attainment tool. Evaluate the system by what it protects and reveals, not by how much activity it stores.",
  "limits": [
    "Most evidence in the time-management meta-analysis is correlational and highly heterogeneous. The checklist is an editorial synthesis, not a validated productivity scale."

  "example": "A week with fewer scheduled blocks can be the better system if the important deliverable moved, interruptions were bounded and recovery stayed intact.",
  "check": "At review time you can point to goal progress, protected capacity and one adaptation made from new information; calendar fullness is not the score.",
  "checklist": [
    "Can I see progress on the few goals that matter, not only completed tasks?",
    "Does the system protect time from low-value intrusion as well as allocate it?",
    "Can the plan adapt when capacity or evidence changes?",
    "Does it preserve important recovery and nonwork commitments instead of treating them as leftover time?"
