Measure context-switch friction without self-blame

Inputs: [WORK LOG], [INTERRUPTION TYPES], [CONSTRAINTS]. Categorise interruption sources, restart time and avoidable versus essential switches. Suggest two reversible environment or process changes. Output: A small summary table and one-week experiment. Check: Do not treat limited observations as a productivity diagnosis. If essential information is missing, identify it rather than filling the gap with a guess. Record whether interruptions were chosen, required or unavoidable before proposing a change.
