Struct TokenTrace 

pub struct TokenTrace {
    pub t: usize,
    pub token_id: u32,
    pub confidence: f32,
    pub active_skill: Option<String>,
    pub recon: Option<f32>,
    pub switched: bool,
}

One row of the structured telemetry trace (B4): the model’s internal routing state at the moment a token was emitted. Every field is a quantity the runtime already computes — nothing is inferred or estimated (anti-principle: only measured bytes).

Fields

t: usize

0-based index within the generated slice.

token_id: u32

The emitted token id.

confidence: f32

Born mass on the emitted token (softmax prob) — how sure the model was.

active_skill: Option<String>

Skill in force while this token was generated (None = backbone).

recon: Option<f32>

Recon error E = ‖r−BBᵀr‖²/‖φ‖² at the last routing eval — coherence with the active skill’s subspace (low = coherent). None = no router or not yet evaluated.

switched: bool

The router changed the active skill right after this token (a domain boundary crossed under the hysteresis barrier).
