• Data races in TypeLookupManager's asynchronous type resolution: callback and request maps, and request_seq_number_, accessed without async_get_types_mutex_

• [Bug] TypeLookupManager destructor deletes reply writer/history before stopping the request processor thread (SIGSEGV in answer_request during participant deletion)

• Endpoint matching deferred on TypeLookup never completes if the reply is not received (no timeout/retry), causing permanent one-directional match loss

• A sample refused by a reader in the same process is never resent, stalling that writer for depth / rate
