## Affects

***

Teams that deploy SILOC with mandatory fact streaming.

## What changed

***

SILOC now validates `STREAMING_CLOUDEVENTS_SOURCE` against the source identity supplied in the current Lerian deployment package. A different value, including leading or trailing whitespace, prevents startup because SILOC derives its broker topics and access-control scope from that identity.

This corrects documentation of the current contract. It does not announce a runtime release.

## Impact

***

**Classification: Action required.** An absent, altered, or whitespace-padded source value blocks the SILOC service from starting.

## What you need to do

***

<Steps>
  <Step>Copy `STREAMING_CLOUDEVENTS_SOURCE` exactly from the current Lerian deployment package.</Step>
  <Step>Remove surrounding whitespace and verify the value through your deployment configuration.</Step>
  <Step>Validate startup before the next settlement deployment.</Step>
</Steps>

### Deadline

Update configuration before the next SILOC start or redeployment.
