Persistence: - one delivery state per sink, with claim, crash recovery, and index replacement - retention for delivered and dead records - LMDB writes moved off the event loop Pipeline: - one attempt per dispatch, with the next try scheduled by next_retry_at - backpressure through max_queue_size - reload re-reads YAML; SIGTERM drains and SIGHUP reloads Plugins: - journald source, enricher and filter processors, Loki sink - built-ins register when entry points are missing API and CLI: - health, metrics, per-sink queue, and dead-letter replay - startup prints the pipeline on one line Tests: - dispatch, plugins, metrics, CLI, and persistence coverage
