# <Source Title> — Cheatsheet

<!--
BUDGET: under 1,200 tokens. One printed page you keep beside you while working.
The constraint is the point: it forces ranking.

This is the most differentiated file in a compiled skill. Anyone can grep the glossary for a
term. This file captures the author's JUDGMENT — the decisions they would make and why. It is
what turns "I know the words" into "I would act the way the author would."

AVOID: bare term → definition rows (that is glossary.md) and prose paragraphs (that is a
chapter file). Every line here helps the reader DECIDE something.
-->

## Decision Rules

<!-- Highest priority. The if/then logic the author applies, stated so it can be used without
     re-reading the book. Always include the "because" — a rule without its reason cannot be
     applied outside the case it was learned on. -->

| When | Do | Because |
|------|----|---------|
| <situation> | <action> | <the author's reason> |
| <situation> | <action> | <the author's reason> |

## Choosing Between <N> Options

<!-- For branching choices. Nested bullets or a small table — whichever reads faster. -->

- Is <condition>?
  - **Yes** → <option A>, because <reason>
  - **No** → is <second condition>?
    - **Yes** → <option B>
    - **No** → <option C>

## Trade-off Matrix

<!-- Competing options scored on the dimensions THIS AUTHOR cares about, so the reader can
     pick under their own constraints rather than taking the author's default on faith. -->

| Option | <dimension> | <dimension> | <dimension> | Pick when |
|--------|-------------|-------------|-------------|-----------|
| <option> | <high/med/low> | <…> | <…> | <condition> |
| <option> | <…> | <…> | <…> | <condition> |

## Thresholds & Defaults

<!-- The specific numbers, ratios and rules of thumb the author actually commits to. If the
     author gives a number, it belongs here — vague guidance is not a threshold. -->

| Metric | Threshold | What it means |
|--------|-----------|---------------|
| <metric> | <number> | <what crossing it implies> |

## Tells & Smells

<!-- Fast heuristics for recognizing a situation: "if you see X, you are probably in Y."
     This is recognition-primed decision making — see references/knowledge_extraction_canon.md.
     It is what the reader needs when they do NOT already know what they are looking at. -->

| If you see… | You are probably… | Check |
|-------------|-------------------|-------|
| <observable signal> | <the named situation> | <the confirming test> |
