UDP IPC

UDP IPC

Generated with Grok Build: Grok 4.5 · xAI Imagine (/imagine)

Non-blocking UDP JSON messages (no newlines required). Default bind 127.0.0.1:9898.

Message types

Stimuli

Drive the network input vector (clamped / truncated to num_channels).

{"type":"Stimuli","values":[0.5, -0.2, 0.0, 1.0]}

• Values beyond channel count are truncated.
• Applied before the next network.step.

LearningReward

Apply neuromodulator deltas (negative deltas ignored for dopamine/cortisol paths — see tests).

{"type":"LearningReward","dopamine_delta":0.3,"cortisol_delta":0.2}

GetNeuroState

Request a JSON snapshot of neuromodulator levels and spike count (response sent to the requester).

{"type":"GetNeuroState"}

Behavior notes

• Invalid / empty JSON does not panic (ignored).
• Empty receive queue → no-op for that tick.
• Handled in process_udp_messages on the main loop path.
