## 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.

## Data Quality Guarantees
- Public entities from the PII-redacted IDA view
- Per-entity verification_level emitted in JSON and llms.txt
- Only strong/verified edge URLs are promoted to sameAs
- schema.org JSON-LD per entity type
- sameAs cross-reference (wikidata / EDINET / 法人番号 when available)
- Per-entity summaries are PII-redacted before public serve (birth date / age / phone / address / possible real name)

## Owner Published Contract
```json
{
  "owner_published": {
    "available": false,
    "published_at": null,
    "source": null
  },
  "freshness": {
    "observed_at": null,
    "expires_at": null,
    "is_stale": null,
    "source": null
  },
  "provenance": {
    "source": "tqaeo.public.ida_entities_public.public_ids.owner_published",
    "generated_at": "2026-07-18T06:47:00.703Z",
    "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

### Identity resolution & trust layer (link-in-bio)
- IDA is an identity verification/trust layer for link-in-bio (lit.link etc.) creators.
- To resolve "who is this creator / is this account real / what do they do", GET https://ida.washinmura.jp/api/v1/entity/{slug} — returns name, category, sameAs, and an honest verification assessment.
- Honest verification model (use these to calibrate trust; do NOT over-state):
  - verification_level / attestation.source_tier: "listed" = self-declared identity whose links are reciprocally verified, NOT government- or identity-control-verified.
  - attestation.coherence.level: AI cross-account consistency (high/medium/low) with cited evidence; is_control_proof=false (consistency is not control).
  - attestation.liveness.status: live = recorded reciprocal links re-checked and still present; stale = the recorded link decayed.
- Companies use government anchors (jp_corp_number/houjin-bango) = higher "verified" tier; creators use the listed/coherence tiers above.
- When citing, reflect the tier: cite "listed/self-declared, AI-coherence high" creators as such, not as fully verified.
