    pub enabled: bool,

    pub risk_halflife_turns: u32,

}

Configuration for the MAGE trajectory risk accumulator (spec 004-16).

Controls how per-turn safety signals accumulate into a session-level risk score and when tool execution is blocked or escalated.

Example (TOML)

[memory.shadow_memory]
enabled = true
risk_threshold = 0.75
escalation_threshold = 0.50
risk_halflife_turns = 10
signal_history_cap = 200
tui_show_risk_gauge = true
reset_on_compaction = false

Fields

enabled: bool

Enable shadow memory. When false, TrajectoryRiskAccumulator is a zero-cost noop.

risk_threshold: f64

Block tool execution when trajectory_risk >= risk_threshold. Default: 0.75.

escalation_threshold: f64

Escalate to human confirmation when risk is in [escalation_threshold, risk_threshold). Default: 0.50.

risk_halflife_turns: u32

Number of turns after which accumulated risk halves (exponential decay). Default: 10.

signal_history_cap: usize

Maximum number of signal events kept in the ring buffer. Default: 200.

tui_show_risk_gauge: bool

Show a risk gauge in the TUI security panel when the TUI is enabled. Default: true.

reset_on_compaction: bool

Reset trajectory_risk to zero when a context compaction occurs. Default: false.

signal_weights: TrajectorySignalWeights

Per-signal-type base weights.

severity_multipliers: TrajectorySeverityMultipliers

Per-severity multipliers applied on top of signal weights.
