# Atlas v0.0.2 Release Notes

## Summary
Atlas v0.0.2 introduces the first coherent entity-centered data contract for Atlas responses and triples.

## Highlights
- Canonical entity core stabilized around:
  - `atlas_id`
  - `canonical_label`
  - `entity_type`
- Claims are now attached to the entity as first-class statement objects.
- Claim-level provenance is explicit and retained per claim.
- `atlas_id` is now opaque/hash-based (semantic parsing removed).
- MID/QID are represented as identifier claims.

## Payload harmonization
To align semantics across similar payload objects:
- Google Trends payload now uses `retrieved_at` (previously `resolved_at`).
- Wikidata payload keeps `retrieved_at`.
- Both payloads expose `source` and timestamp fields with aligned meaning.

## Notes
This version intentionally prioritizes model coherence and contract clarity while Atlas is still establishing its stable baseline.
