Native building blocks for Dart, reached through dart:ffi: transports (QUIC/WebTransport, Zenoh, NATS), certificates and mutual TLS, RFC 5424 logging, device protocols and on-device inference. Extracted from an offline-first point-of-sale system and published separately so each is usable on its own.
A syslog sink for Dart — RFC 5424 framing, RFC 5425 delivery over TLS, and a bounded on-disk spool so records survive a crash and never block the caller.
Dart bindings for Zenoh over a narrow C ABI - publish, subscribe and liveliness for offline-first fleets, with an explicit answer to the stale Zenoh ID after a restart.
NATS and JetStream over a native client, with a durability contract - an acknowledgement means fsynced to disk by default, or says plainly what else it meant.
SPIFFE identity in pure Dart. Parses and validates spiffe:// IDs and trust domains, and reads X.509-SVID and JWT-SVID documents. Verifies nothing.#spiffe#identity#security#x509#jwt
