Struct PolicyRef 

pub struct PolicyRef {
    pub id: String,
    pub explore: bool,
    pub propensity: Option<f64>,
    pub mode_profile: Option<String>,
}

Reference to the policy that produced a decision.

Fields

id: String

Policy identity/version, e.g. "static@v0" or "bandit@v3".

explore: bool

Whether this decision was a deliberate exploration draw (bounded, §, only in enforce).

propensity: Option<f64>

The probability the logging policy assigned to the start rung it chose — the Horvitz-Thompson denominator for IPS / SNIPS off-policy evaluation.

None for deterministic (non-exploring) policies. skip_serializing_if keeps old trace bytes byte-identical when None, preserving hash-chain compatibility with existing logs. Only populated when [escalation.exploration] is configured.

mode_profile: Option<String>

Resolved routing-mode profile when it was explicitly set (header / route / global env). None means Balanced was in effect (the default, no override active). Absent from the JSON when None → byte-identical serialization for all existing traces.
