# SILOC MQ activation contract

> SILOC inbound SFN processing is driven by its MQ connection descriptor, not an SFN_INGEST_ENABLED setting.

## Affects

Teams that configure SILOC inbound SFN processing.

## What changed

The documentation now correctly states that SILOC activates inbound SFN processing from its MQ connection descriptor. `SFN_INGEST_ENABLED` is not a SILOC setting.

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

Remove reliance on `SFN_INGEST_ENABLED` from deployment templates and runbooks. Configure the complete [SILOC MQ connection descriptor](/en/rails/siloc/siloc-environment-variables): `MQ_HOST`, `MQ_CHANNEL`, `MQ_QUEUE_MANAGER`, `MQ_SEND_QUEUE`, or `MQ_RECEIVE_QUEUE` activates fail-closed validation; `MQ_PORT`, `MQ_TLS_ENABLED`, and `MQ_SSL_KEY_REPOSITORY` alone do not.

### Deadline

Update affected configuration before the next SILOC deployment.
