Summary
TunnelMqttTransport— MQTT 3.1.1 (QoS 0 only) over a caller-supplied byte pipe:setPipeSend(fn)/injectBytes()/notifyPipeUp(bool), exposing theMqttTransportAPI subset consumers use (setClientId,subscribe/unsubscribe,publish, topic-awareonMessage,send(doc, opts)). Keepalive via PINGREQ/PINGRESP with 1.5× timeout; subscriptions replay automatically after every reconnect; QoS/retain accepted for drop-in compatibility and always sent as QoS 0.MqttCodec— the QoS-0 packet codec underneath: encoders with golden-byte tests against the 3.1.1 spec, and an incremental decoder that tolerates arbitrary stream splits, skips packet types outside the subset, and bounds packet/topic sizes.WebSocketTransporttagged binary frames —sendBinaryTagged(tag, data, len)/onBinaryTagged(cb): a 1-byte application-defined channel tag inside the same WS frame, mechanism only. RegisteringonBinaryTaggedclaims the single binary receive slot (last registration wins, per Courier's callback model).Byte-pipe design keeps the transport fully host-testable: 48 new native test cases (23 codec, 25 transport) plus 5 tagged-frame tests on the WS transport.
Closes #24. Downstream halves: inanimate-tech/hawthorn-firmware#157 (adoption, opt-in flag), inanimate-tech/hawthorn-worker#157 (server demux). Motivation and hardware measurements: inanimate-tech/hawthorn-firmware#156.
