Enum CalibrationMode 

#[repr(u8)]
pub enum CalibrationMode {
    AttentionMass = 0,
    CausalNecessity = 1,
    AdaptiveCausal = 2,
}

Head-calibration score source (Plan 358, Research 362).

#[repr(u8)] for sync-friendly 1-byte representation.

Variants

AttentionMass = 0

Observational needle attention-mass (RTPurbo Plan 126 default). Cheaper: a single forward pass + per-head mass scan.

CausalNecessity = 1

Causal necessity via activation/path patching IE score (Plan 358). Strictly stronger — excludes correlated bystanders — but requires n_heads × n_calibration_samples patched forward passes. Requires the causal_head_importance feature on the consuming crate.

AdaptiveCausal = 2

Adaptive cheap-proxy escalate (Proposal 004 — OUR INVENTION, not from HydraHead). Uses an OV-circuit proxy (attention_mass / ||OV_out||) to detect bystander suspects, then escalates to Plan 358’s causal patching only on those k suspects instead of all n_heads. Pays zero patched forwards when there are no bystanders (degenerates to AttentionMass). Requires the adaptive_causal_calibration feature.

UNVALIDATED. Promotion to default is blocked on G1 (proxy precision) and G2 (cost reduction), both deferred to riir-engine. Unlike the other two modes, the caller must supply per-head OV output norms (from a real transformer forward) — see calibrate_from_adaptive_causal.
