## B. the two policy beans the starter creates
167-  public RetryDecisionEngine retryDecisionEngine() {
179-  public DeadLetterOrchestrator deadLetterOrchestrator(MessagePublisher publisher) {

## C. who accepts those two types as a constructor/field dependency
--- RetryDecisionEngine

## D. is each of those dependents ever constructed?
KafkaRetryExecutor           NEVER CONSTRUCTED
KafkaDeadLetterPublisher     NEVER CONSTRUCTED
RabbitDeadLetterPublisher    NEVER CONSTRUCTED

## E. control: the publish path IS constructed in production
--- DefaultMessagePublisher
src/messaging/messaging-spring-boot-starter/src/main/java/dev/caskeleton/messaging/autoconfigure/MessagingCoreAutoConfiguration.java:446:    return new dev.caskeleton.messaging.runtime.DefaultMessagePublisher(
--- TransportMessagingRuntime
src/messaging/messaging-spring-boot-starter/src/main/java/dev/caskeleton/messaging/autoconfigure/MessagingCoreAutoConfiguration.java:476:          new dev.caskeleton.messaging.runtime.TransportMessagingRuntime(
--- DefaultRetryDecisionEngine
src/messaging/messaging-spring-boot-starter/src/main/java/dev/caskeleton/messaging/autoconfigure/MessagingCoreAutoConfiguration.java:168:    return new DefaultRetryDecisionEngine(new BackoffCalculator());
--- DeadLetterOrchestrator
src/messaging/messaging-spring-boot-starter/src/main/java/dev/caskeleton/messaging/autoconfigure/MessagingCoreAutoConfiguration.java:180:    return new DeadLetterOrchestrator(publisher);

## F. control: the consume path is constructed only in tests
KafkaConsumerRegistrar         src/main=0  src/test=4
RabbitConsumerRegistrar        src/main=0  src/test=1
KafkaBatchConsumerRegistrar    src/main=0  src/test=0
RabbitBatchConsumerRegistrar   src/main=0  src/test=1
DefaultDeliveryProcessor       src/main=0  src/test=1

## G. every file that acts on a RetryDecision variant
src/messaging/messaging-kafka/src/main/java/dev/caskeleton/messaging/kafka/KafkaRetryExecutor.java
src/messaging/messaging-policy/src/main/java/dev/caskeleton/messaging/policy/DefaultRetryDecisionEngine.java
src/messaging/messaging-policy/src/main/java/dev/caskeleton/messaging/policy/RetryDecision.java
src/messaging/messaging-policy/src/test/java/dev/caskeleton/messaging/policy/RetryDecisionEngineTest.java

## H. the startup gate that IS called
134:    new DestinationProfileValidator().validateAll(registered);
