## Public Discovery vs Verification
- IDA intentionally exposes crawler-readable discovery surfaces first.
- Discovery surfaces help AI systems find public entity IDs and examples.
- Discovery contract: https://ida.washinmura.jp/api/v1/ai-search/discovery
- Architecture contract: https://ida.washinmura.jp/api/v1/ai-search/architecture
- Trust Oracle: https://ida.washinmura.jp/api/v1/ai-search/verify?claim=...&entity=...&source_url=...
- Treat discovery as navigation, not final judgement.
- Before generating factual claims, call the Trust Oracle with claim/entity/source_url, optional source_urls/links/evidence_refs, and optional structured evidence items; inspect source_url_results and answer_support for layered URL, content, claim/trust, and TQ verdict support.
- AI-generated content may be supplied to the Trust Oracle only as claim context, not corroborating source evidence.
- IDA discovery is not a raw database export.

### Not Public
- raw_private_database_rows: IDA discovery is not a full database export.
- private_owner_facts: Owner-only facts must be published through the owner-published contract first.
- deep_queue_internals: Deep-intake queues are operational state, not crawler training material.
- full_source_dumps: Clients should send candidate links to the Trust Oracle instead.
- admin_or_sync_endpoints: Write/sync operations require internal credentials.

## Owner Published Contract
```json
{
  "owner_published": {
    "available": false,
    "published_at": null,
    "source": null
  },
  "freshness": {
    "observed_at": "2026-05-24T15:20:44.865Z",
    "expires_at": null,
    "is_stale": null,
    "source": "entity.last_updated"
  },
  "provenance": {
    "source": "tqaeo.public.ida_entities_public.public_ids.owner_published",
    "generated_at": "2026-06-13T17:56:59.955Z",
    "owner_published_source": null,
    "contract_version": "owner-published-freshness/v1",
    "sameAs_policy": "owner_published_does_not_upgrade_verification_level"
  }
}
```

- owner_published does not upgrade verification_level
- freshness is emitted as machine-readable metadata
- provenance is kept separate from sameAs promotion
