Use notes:
- Treat /version.json and /data/manifest.json as the current deployment and count authority.
- Use /data/entities.json, /data/events.json, and /data/evidence.json for reviewed public records.
- Use /feeds/updates.json or /feeds/updates.xml for reviewed Registry Update entries only.
- Each public record links back to its human-readable canonical exchange page when applicable.
- Supporting record exchange IDs are normalized to the canonical entity ID in the public datasets.
- This is a historical registry, not a live exchange ranking.
- This is not an exchange recommendation site or investment advice.
- Public data and feeds exclude unreviewed candidates, internal monitoring, and private notes.
- Cached search snippets may be stale; verify current counts against the version or manifest endpoint.

## Record-level reviewed bundles
- Index: /data/exchanges/index.json
- Record template: /data/exchanges/{slug}.json
- Each record bundles one reviewed exchange entity with its reviewed events, event evidence references, evidence provenance, relationships, and verification metadata.
- Record-level files use the same reviewed canonical source of truth as the main public datasets.

## Registry statistics
- Current deterministic snapshot: /stats.json
- Deterministic history/trend input: /stats-history.json
- Both outputs are derived from reviewed entity/event/evidence data and do not add fields to canonical records.
