ljg-think
Arrow of Root-Seeking — A vertical deep-drill thinking tool. Given a viewpoint, phenomenon, or question, it drives down like an arrow to the irreducible essence. Use when user says '想透', '追本', '本质是什么', '为什么会这样', '深挖', '钻到底', 'think deep', 'drill down', or wants to trace any idea/phenomenon vertically to its irreducible root. Also trigger when user provides a statement and wants depth analysis, not breadth survey.
1How It Works & Mechanism
Positioned as a vertical deep-drill tool: Given a viewpoint, phenomenon, or question, drill straight down to the irreducible essence.
输入一个观点，一路向下，钻到底。
Fixed logic of drilling layers: Phenomenon → Mechanism → Principle → Axiom, peeling layer by layer along clues until nothing left can be peeled.
表象之下必有机理…机理之下必有原理…原理之下必有公理。
Three iron rules constrain the drill: Vertical over horizontal (only answer 'why is it so'), straight to the core, and layer-by-layer awe.
**纵向，不横向**——每次下钻必须回答"为什么是这样"，不是"还有什么"
Every drill step must shift to a more fundamental explanatory framework (Sociology → Psychology → Biology → Physics → Mathematics → Logic).
从社会学掉进心理学，从心理学掉进生物学，从生物学掉进物理学，从物理学掉进数学，从数学掉进逻辑本身。
Converge upon bottoming-out criteria: Asking 'why' further only yields a tautology, or points to human nature structure / physical laws / logic / existential paradox.
到底的标志：再往下问"为什么"，答案要么是同义反复，要么指向上述四类之一。
Writing requirement is to depict a free fall rather than an analytical report: weightlessness, named layers, ruptures between layers, and a stark, hard-hitting finale.
写一场下坠。不是分析报告。
The number of layers is variable: shallow topics reach the bottom in 3 layers, deep topics in 7 layers, determined dynamically by the model based on the subject.
层数不固定——浅的话题三层见底，深的七层。你自己判断。

- scripts/: Executing local scripts or commands: date +%Y%m%dT%H%M%S and date "+%Y-%m-%d %a %H:%M" (retrieving timestamps for filenames)
- 本地工作目录: File I/O and artifact output: ~/Documents/notes/{timestamp}--追本-{topic}__think.org (Org-mode free-fall notes)
