# RAIL-FAB-WP-0004 - Registry Inventory And Drift Views

## Goal

Make the registry useful as an inspection surface, not only an ingestion
surface.

Agents and humans should be able to ask what a registered repo currently
contains, search across graph/library/artifact data, and compare graph snapshots
to see what changed.

## Tasks

### T01 - Repository Inventory View

```task
id: RAIL-FAB-WP-0004-T01
status: done
priority: high
```

Add a repo inventory view that returns repository metadata, latest snapshot
summary, graph nodes/edges from that snapshot, artifacts, libraries, and counts.

### T02 - Snapshot Listing And Drift

```task
id: RAIL-FAB-WP-0004-T02
status: done
priority: high
```

Expose snapshot listing and graph drift between two snapshots. By default, drift
compares the latest snapshot with the previous snapshot for the same repo.

### T03 - Registry Search

```task
id: RAIL-FAB-WP-0004-T03
status: done
priority: medium
```

Add a simple search endpoint across repositories, graph nodes, artifacts, and
libraries.
