Chain of Thought
Chain of Thought (CoT) taught AI to "think step by step." CLN
upgrades this linear monologue into a hierarchical logic tree, making reasoning
visible, auditable, and branching.
01/Definition
AI Foundation
= Chain of Thought: A prompting technique where
AI generates intermediate reasoning steps before
reaching a final answer.
= The
"Let's think step by step" protocol.
02/The Linear Limitation
! CoT is a monologue. It
cannot easily branch into scenarios (if/else).
! CoT is hard to audit. The
reader must parse prose to find where logic
failed.
! CoT lacks grouping. Related
concepts are separated by the sequence of words.

04Map vs Narrative
+ When you ask AI for a narrative, you get a
story.
+ When you ask for CLN-reasoning, you get a
map.
* A
map allows you to spot missing branches
instantly.
* The chain is strong but rigid. The tree is
strong and flexible.
