Module node_controller 

Core-side node controller (A2): g4a parsing lives here, not on C2.

C2’s restreamer forwards opaque multiplex DATA. Core drains the stream, strips the inner Noise layer (caller-supplied transport), then this module decodes g4a frames (RoutedNodeEvent / RoutedNodeResponse / C2ServerFrame).

Structs

DrainWorker

Drain worker: pull envelopes from C2 and parse g4a on core.

OperatorLink

Operator control routed through core (A2): core sends g4a requests down a node’s control stream and correlates replies. C2 relays the bytes without parsing them.

Enums

G4aMessage

Decoded g4a traffic from one drain envelope (after outer/inner crypto).

NodeControllerError

OperatorError

Functions

handle_drain_envelope

Handle one drain envelope: only g4a channels are parsed; others stay opaque.

is_g4a_channel

Returns true when the channel kind is one of the g4a.* multiplex kinds.

parse_g4a_payload

Parse opaque payload bytes as a g4a message. C2 must not call this.
