Module shadow 

MAGE shadow memory stream — trajectory-level risk accumulation (spec 004-16).

TrajectoryRiskAccumulator maintains a per-session rolling risk score by ingesting AuditSignalType events from zeph-sanitizer. The score decays exponentially between turns and is used to gate tool execution when it exceeds a configured threshold.

When enabled = false (default), every method is a zero-cost no-op — no allocations, no computation.

Example

use zeph_memory::shadow::{TrajectoryRiskAccumulator, AuditSignalType, Severity};
use zeph_config::TrajectoryRiskAccumulatorConfig;

let mut acc = TrajectoryRiskAccumulator::new_noop();
assert_eq!(acc.current_risk(), 0.0);
assert!(!acc.is_blocked());
