FIG. P2 — Conservative networking stack. Each layer applies operator-configured filters. No protocol auto-negotiation, no hidden telemetry channels, no cloud service dependency. The network stack serves the operator, not the network. Rejected external influences are shown crossed out on the right.

NETWORK CONSTRAINT: All protocols are implemented defensively. Experimental congestion algorithms, opportunistic encryption downgrade, and auto-negotiated cloud endpoints are categorically excluded. The operator configures every network parameter explicitly. See src/NET_CONSTRAINTS.
