## Definitions

### `app.kiesel.facts.claimReview`

**Type**: `record`

A single fact-check entry. Each record is one claim reviewed by one publisher, with one rating. Multi-claim articles produce one record per atomic claim. Records are mutable (publishers may correct), so consumers should treat the most recent CID as authoritative.

**Key**: `tid`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `url` | `string` (uri) | Yes | The publisher's article URL — the canonical citation for the verdict text and reasoning. Maps to schema.org/ClaimReview#url. |
| `author` | `ref` → `#publisher` | Yes | The publisher of the fact-check. Maps to schema.org/ClaimReview#author. |
| `subject` | `ref` → `com.atproto.repo.strongRef` | No | Optional strongRef to an atproto record (e.g. a Bluesky post) where the claim was originally made. When set, this enables Constellation-style backlink lookups: 'which fact-checks address this post?'  |
| `sdLicense` | `string` | No | Optional Creative Commons / other licence URL applicable to *this entry's* text. Maps to schema.org/ClaimReview#sdLicense. |

| `itemReviewed` | `ref` → `#claim` | No | Provenance of the claim itself — who made it, where. Maps to schema.org/ClaimReview#itemReviewed. |
| `reviewRating` | `ref` → `#rating` | Yes | The publisher's verdict on the claim. Maps to schema.org/ClaimReview#reviewRating. |
| `claimReviewed` | `string` | Yes | The atomic claim being reviewed. Should be a single falsifiable assertion. Maps to schema.org/ClaimReview#claimReviewed. |
