Ranvier Std (ranvier-std)

Standard transition nodes and utility helpers for Ranvier circuits.

Guard Transition Nodes

Guard nodes are Transition<T, T> — they pass input through on success or return Fault on rejection. Every guard is visible in the Schematic as a named node.

Guard Purpose
CorsGuard Validates request origin against allowed origins
RateLimitGuard Per-client token-bucket rate limiting
SecurityHeadersGuard Injects HSTS, CSP, X-Frame-Options into Bus
IpFilterGuard Allow-list / deny-list IP filtering 
use ranvier_std::prelude::*;

let pipeline = Axon::new("Guarded API")
    .then(CorsGuard::new(cors_config))
    .then(RateLimitGuard::new(100, 60_000))  // 100 req/min
    .then(IpFilterGuard::allow_list(["127.0.0.1"]))
    .then(business_logic);
