## Description

A structured synthesis over a graph component. The island record points to actual network.cosmik.connection records; it does not embed edge data.

## Definitions

### `org.latha.island`

**Type**: `record`

A Stigmergic island: a centroid URL, pointers to network.cosmik.connection records, and analysis of the resulting graph component.

**Key**: `tid`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `forkOf` | `string` (at-uri) | No | Original org.latha.island AT URI when this record is a fork/update of another user's island. |
| `source` | `ref` → `#sourceRef` | Yes | The island centroid/canonical source URL. |
| `analysis` | `ref` → `#structuredAnalysis` | Yes | The structured analysis output. |
| `carryRefs` | `array` | No | Carry entities cross-referenced in this analysis. Carry stays local-first — only summaries are included unless explicitly published as companion records. |
| `createdAt` | `string` (datetime) | Yes | When this synthesis was created. |
| `updatedAt` | `string` (datetime) | No | When this synthesis was last updated. |
| `connections` | `array` | Yes | AT URIs of actual network.cosmik.connection records. The island does not embed edge source/target/type/note data. |

### `org.latha.island#sourceRef`

**Type**: `object`

Reference to the source/centroid for this island.

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `cid` | `string` | No | CID of the source record at time of analysis. |
| `uri` | `string` (uri) | Yes | Canonical HTTPS URL of the island centroid. |
| `collection` | `string` | No | Collection being analyzed. For islands over connection graphs this is usually network.cosmik.connection. |

### `org.latha.island#carryCrossRef`

**Type**: `object`

Cross-reference to a carry entity, translated to AT Protocol addressable format.

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `atUri` | `string` (at-uri) | Yes | AT Protocol URI for this carry entity (if published as companion record). |
| `carryId` | `string` | No | Original carry entity ID for local correlation. |
| `summary` | `string` | No | Summary of the carry entity. |
| `entityType` | `string` | Yes | Type of carry entity. |

### `org.latha.island#structuredAnalysis`

**Type**: `object`

The structured output of a Strata analysis run.

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `title` | `string` | No | A concise sentence capturing the core argument or narrative arc of this analysis. |
| `themes` | `array` | Yes | Key themes identified in the source. |
| `tensions` | `array` | No | Tensions or contradictions with existing claims. |
| `synthesis` | `string` | No | Prose synthesis connecting the source to existing knowledge. Legacy plain-text format. |
| `highlights` | `array` | No | AT URIs of network.cosmik.connection records flagged as semantically significant by the analysis. Hot edges. |
| `synthesisDoc` | `string` (at-uri) | No | AT URI of a pub.oxa.document record containing the rich-text synthesis. Takes precedence over the plain-text synthesis field when present. |
| `openQuestions` | `array` | No | Questions raised by the analysis. |
