## 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: 1,132
- With proof: 915 (80.8%)
- With docstring: 0 (0.0%)
- Libraries: 44

### By type

| Type | Count |
|---|---|
| pred | 338 |
| sig | 288 |
| fun | 165 |
| fact | 124 |
| assert | 80 |
| check | 73 |
| run | 64 |

## Example

```
AVTree {
  values: set Value,
  attributes: set Attribute,
  root: values - Wildcard,
  av: attributes one -> some (values - root),
  va: (values - Wildcard) one -> attributes
}
{
  // values (and attributes) of tree are those reachable from root
  values = root.*(va.av)
}
```

- type: sig | symbolic_name: `AVTree` | algorithms/discovery/ins.als

## 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`.
