## Schema

| Column | Type | Description |
|--------|------|-------------|
| statement | string | Declaration signature/claim with the leading keyword removed (verbatim slice); the full declaration minus its proof |
| proof | string | Verbatim proof/body, empty if the declaration has none |
| type | string | Declaration keyword |
| symbolic_name | string | Declaration identifier |
| library | string | Sub-library |
| filename | string | Repository-relative source path |
| imports | list[string] | File-level `Require`/`Import` modules |
| deps | list[string] | Intra-corpus identifiers referenced |
| docstring | string | Preceding documentation comment, empty if absent |
| source_url | string | Upstream repository |
| commit | string | Upstream commit extracted |

## Statistics

- Entries: 771
- With proof: 516 (66.9%)
- With docstring: 0 (0.0%)
- Libraries: 7

### By type

| Type | Count |
|---|---|
| theorem | 243 |
| definition | 227 |
| operator | 215 |
| tactic | 46 |
| notation | 40 |

## Example

```
bottom-diverges : [ ¬ bot ⇓ ]
{
  unfold <not implies>;
  intro; aux {auto; unfold <has-value>; auto};
  bot-div #1
}.
```

- type: theorem | symbolic_name: `bottom-diverges` | example/approx.jonprl

## Use

Each declaration is split into a `statement` (signature/claim) and a `proof` (body) that are disjoint
and together form the complete declaration, for proof modeling, autoformalization, retrieval, and
dependency analysis via `deps`.
