Attention Residue
! You never fully arrive at a new task @ Sophie Leroy (2009)
When you switch from Task A to Task B, part of your brain stays stuck. Attention Residue is the cognitive "sticky tape" that drags down your performance.
01/Definition Neural Lag
= Attention Residue: Cognitive resources that remain focused on a prior task after switching.
= The Zeigarnik Effect: Unfinished tasks create "open loops" that drain background energy.
TASK A
TASK B (DEGRADED)
02/The Cost of Switching
- Reduced performance on high-complexity tasks (Task B).
- Increased "time-to-depth": it takes longer to reach flow state.
- Accumulated fatigue: 10 switches = 10 layers of residue.
03/The CLN Closure Protocol Systemic

Before leaving Task A, use a Closure Block to externalize the state:

= Status: API integrated, waiting for key.
? Issue: Rate limiting on the dev server.
. NEXT: Verify key @tomorrow morning.
+ Externalizing closes the internal loop.
+ The paper holds the thought so the brain can release it.
04/Write to Release
* CLN provides the syntax to mark thoughts "done for now."
* A single line is often enough to dissolve the residue.
= Write the state. Free the mind.
