Please report security issues privately through GitHub's security reporting facilities when available. Do not include credentials, production message payloads, or other sensitive data in public issues.

RelayGrid v0.1 is an in-memory runtime library. It does not authenticate producers or consumers, encrypt transport, persist payloads, or provide multi-tenant isolation.

Callers are responsible for validating message payloads before handing them to application handlers. Exception messages copied to a dead-letter record can contain handler-provided text; applications should avoid putting secrets in exception messages or should sanitize them in their dead-letter implementation.

A dead-letter sink failure faults the runtime rather than dropping work silently.
