docs: Dead Letter Queues tutorial (closes #3092)#3099
Merged
Conversation
The tutorials index linked to a title-only stub. Adds a full tutorial: when a message gets dead lettered, the database-backed vs native-transport DLQ distinction, and inspecting/replaying via CLI (storage replay), SQL, the REST API, and IDeadLetters. Reuses existing verified snippets. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Closes #3092.
docs/tutorials/dead-letter-queues.mdwas a title-only stub, yet the tutorials index linked to it with a real description. This writes the full tutorial:RetryWithCooldown/MoveToErrorQueuepolicies).wolverine_dead_letterstable and native transport DLQs (RabbitMQ/SQS/etc.), and how to opt out of native dead-lettering.dotnet run -- storage counts/replay, the SQLreplayableflag, theMapDeadLettersEndpoints()REST API, and theIDeadLettersprogrammatic API.All embedded code uses existing, verified snippets (
sample_exponential_backoff,sample_send_to_error_queue,sample_configuring_error_handling_with_attributes,sample_disable_rabbit_mq_dead_letter_queue,sample_register_dead_letter_endpoints,sample_enabling_dead_letter_queue_expiration) hydrated via mdsnippets — no new source code. Two short inline blocks use verified APIs (store.DeadLetters,MarkDeadLetterEnvelopesAsReplayableAsync).Found during the documentation review (#3089). Prose wording is a draft open to your edits.
