# LDC-E0201 — The sentence stops where the language does not expect it

## What it means

After the reader stage, the parser groups characters into declarations:
headers, entities, relations, rules. Each shape has a fixed skeleton, and a
token that fits none of the skeletons stops the parse at that spot. The
most common shape of this refusal is a small slip — a missing separator, a
digit where a name must stand, a block left open.

The reported position is where the expectation broke, which is usually one
token past the actual slip. Read the line from its start: the missing or
misplaced piece is just before the caret.

## Example

```law
language "law.core" version "0.2";
package demo.diagnostics version "0.1.0";
namespace "urn:law:demo:diagnostics";

entity 123;
```

## Fix

```law
language "law.core" version "0.2";
package demo.diagnostics version "0.1.0";
namespace "urn:law:demo:diagnostics";

entity Applicant;
```

## Engine message

The engine reports this in its own wording:

```text
example.law:5:8: error LDC-E0201: expected a name (entity name), found "123"
```
