Distillation Framework · Feb 2026
Progressive Summarization
Don't let your notes die in a "one-time dump". Progressive
Summarization turns notes into assets by distilling them in
layers. CLN operators allow you to increase signal density without losing the
original raw context.
01/The Stack of Insight
Layer 1: Raw Capture (The messy details)
Layer 2: Core Concepts (Bolded ideas)
Layer 3: Key Phrases (Highlights & Risks)
Layer 4: Executive Summary (Your
synthesis)
02/CLN Operator Mapping
Syntax
* Layer
1: Use for raw quotes and initial fleeting
thoughts.
= Layer
2: Use for the defining claim or core fact.
! Layer
3: Use
!, +, or
- to call out high-signal details.. Layer
4: Use indented
. to record your
final synthesis.
03Evolving a Note
* (L1) "Einstellung
effect: using a familiar solution even if a better one exists."
= (L2) Einstellung
effect: fixation on known patterns blocks discovery.
! (L3) Especially
dangerous for experts with entrenched habits.
. (L4) Implication:
Force yourself to list 3 'naive' approaches first.
*
Self-Test: Does Layer 4 replace Layer 1? || No, Layer
1 is kept indented as context to prevent meaning loss.

04/Cognitive Benefits
+ Serial
Position Effect: Creates multiple memorable
touchpoints in a single note.
+ Active
Cues: Turns passive records into triggers for
your brain.
!
Note: Summarize only when you revisit the note
— don't do it all at once!
