# get\_delta\_report\_target — Compare a target within a delta report

Compare a target within a delta report

Compare a target within a delta report

## What it does

For a delta report and a chosen target object, return the comparison for that target — either how its evidence changed between the compared report snapshots (live-vs-archived delta), or how the selected models differ for the anchor→target pair (specific-anchor delta).

**When to use:** you have a delta report (from list\_delta\_reports / get\_delta\_report) and want to drill into ONE target; the user asks what changed for a specific gene/target between the compared runs (which evidence was added/removed); the user asks why two models score the same anchor→target pair differently (specific-anchor delta reports).

**When NOT to use:** you want the delta report's overview / top movers across all targets (use get\_delta\_report); you want the org's delta report inventory (use list\_delta\_reports); you want a single report's ranked scores with no comparison (use get\_report\_scores).

**Parameters:**

* `deltaReportId` — the delta report's id (its uuid, from list\_delta\_reports / get\_delta\_report)
* `targetId` — the target object's uuid to compare (e.g. a gene from get\_delta\_report.targets / get\_report\_scores) — the SECOND object analyzed against the delta report's anchor

**Returns:** An object keyed by the delta report's `type`. Common fields: deltaReportId, type, anchorObject ({ uuid, displayName }), target (the resolved target node { uuid, displayName, dbLabels } — echoed so you can confirm the uuid anchored on the object you meant). For a LIVE-VS-ARCHIVED delta: reports (the compared reports), perReportScores (\[{ reportId, score, normScore }] — the target's total score in each), and evidenceDelta ({ newerReportId, olderReportId, added\[], removed\[] (each { evidenceUuid, displayName, weight, graphPath }), changed\[] (lines whose weight/pythonCode changed, with olderWeight/newerWeight + the change flags), unchangedCount }). For a SPECIFIC-ANCHOR delta: models (\[{ modelId, modelName, contributingEvidence: \[{ evidenceUuid, displayName, weight, rawScore, edgeScore }] }] — the evidences each model fires on the anchor→target edge; edgeScore is the normalized per-evidence score on that edge) and summaryText (a plain-text per-model summary). A bad deltaReportId OR a targetId that resolves to no object returns a 404 Not Found error.

| Parameter       | Type   | Required | Description                                                                                                                                                            |
| --------------- | ------ | -------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `deltaReportId` | string | yes      | the delta report's id (its uuid, from list\_delta\_reports / get\_delta\_report)                                                                                       |
| `targetId`      | string | yes      | the target object's uuid to compare (e.g. a gene from get\_delta\_report.targets / get\_report\_scores) — the SECOND object analyzed against the delta report's anchor |
