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. ### Public Crawl Allowlist - root_llms: https://ida.washinmura.jp/llms.txt (allow) - sitemap_index: https://ida.washinmura.jp/sitemap.xml (allow) - golden_example: https://ida.washinmura.jp/ai/guide-washinmura-jp/ja/ (allow) - entity_html: https://ida.washinmura.jp/{slug} (allow) - entity_json: https://ida.washinmura.jp/api/v1/entity/{slug} (allow) - entity_llms: https://ida.washinmura.jp/ai/{slug}/llms.txt (allow) - mcp_manifest: https://ida.washinmura.jp/api/v1/mcp/manifest (guide) - discovery_contract: https://ida.washinmura.jp/api/v1/ai-search/discovery (guide) - architecture_contract: https://ida.washinmura.jp/api/v1/ai-search/architecture (guide) - trust_oracle: https://ida.washinmura.jp/api/v1/ai-search/verify (use_on_demand) ### 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": "2026-05-23T03:43:05.104Z", "expires_at": null, "is_stale": null, "source": "entity.last_updated" }, "provenance": { "source": "tqaeo.public.ida_entities_public.public_ids.owner_published", "generated_at": "2026-06-13T02:06:34.931Z", "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 ## BEVN Crawler Entry Points - IDA: https://ida.washinmura.jp/llms.txt | https://ida.washinmura.jp/sitemap.xml - AEO: https://aeo.washinmura.jp/llms.txt | https://aeo.washinmura.jp/sitemap.xml - AI News: https://ainews.washinmura.jp/llms.txt | https://ainews.washinmura.jp/sitemap.xml
