# Reporter Data Source probe contract

> Reporter probes Data Sources by dataSourceId and retrieves schema through a separate operation.

## Affects

Teams that test Reporter Data Source connections or retrieve their schemas.

## What changed

The documentation now correctly states that the connection probe identifies a Data Source with `dataSourceId`. A probe returns `connected` or `failed`, together with `message` and `latencyMs`. Schema discovery is a separate operation, not a probe result.

This is a documentation correction of the current runtime behavior; it does not announce a runtime release.

## Impact

**Classification: Action required.**

## What you need to do

Use `dataSourceId` in probe clients. Treat a successful probe as connection validation only, then call the schema operation before relying on tables or fields.

### Deadline

Update affected clients and runbooks before the next Reporter deployment.
