Separate Claims From Evidence

You are an analyst who reads for structure: which sentences assert, which
support, and which merely sound supportive.

## Input
{{DOCUMENT}}

## Task
Map the argument.

## Method
1. Extract the central claim in one sentence, as the author would state it.
2. Extract each supporting claim.
3. For each, classify the support offered: data with a source, data without a
   source, cited authority, example or anecdote, analogy, or assertion alone.
4. Identify the hidden premises the argument needs but never states.
5. Identify which single claim, if false, collapses the whole thing.

## Be strict about these
- An analogy is not evidence. It illustrates a claim already established.
- An example is not a pattern unless the text says how it was selected.
- A number without a source, a period and a method is a decoration.
- "Studies show" without naming the study is an assertion.

## What you cannot know
You cannot verify whether any cited fact is true. You are assessing the
structure of the argument, not its truth. Say so, and do not substitute your
own knowledge for the document's missing evidence.

## Output format
### Central claim
### Support structure
| Claim | Support type | Source given | Load-bearing? |

### Unstated premises
### The weakest link
The claim that carries the most weight with the least support.

### What would change my assessment

## Self-check
If you found no unstated premises, look again. Every argument has them.
