PUBLIC SPECIFICATION

CIRE is the runtime signal contract for veterinary AI infrastructure.

VetIOS publishes the CIRE methodology as a versioned telemetry and conformance specification. Its signals describe output structure and publication state; clinical reliability still requires outcome-linked and external validation. The reference implementation remains subject to the VetIOS licence.

Reference formulas

phi_hat

0.0 to 1.0

Differential concentration score

phi_hat = 1 - H(D) / ln(|D|), where H(D) = -sum(p_i * ln(p_i)) over normalized differential probabilities

Higher values mean the differential distribution is more concentrated. Concentration does not establish correctness, calibration, or clinical actionability.

input_m_hat

0.0 to 1.0

Input quality risk score

input_m_hat = 0.40 * missingness + 0.35 * contradiction_rate + 0.25 * out_of_distribution_rate

Higher values mean the clinical input is incomplete, contradictory, or outside the supported operating envelope.

delta_rolling

negative to positive real number

Rolling runtime signal drift

delta_rolling = EMA(delta_hat, alpha = 0.1)

Tracks short-horizon movement in the runtime signal compared with prior inference behavior.

sigma_delta

0.0 and above

Runtime signal volatility

sigma_delta = standard_deviation(last 50 delta_hat values)

Higher values indicate less stable runtime signal behavior across recent events.

cps

0.0 and above

Runtime perturbation score

cps = 0.40 * (1 - phi_hat / phi0) + 0.35 * max(0, -delta_rolling) / phi0 + 0.25 * sigma_delta / phi0

Composite runtime score used to place an output inside a configured publication envelope. It does not measure diagnostic correctness.

Safety states
nominalHIGH

The runtime signals are within the configured publication envelope.

Publish the differential with its runtime status; retain clinician review and outcome validation requirements.

warningREVIEW

The inference should be interpreted with clinician review because runtime stability has weakened.

Surface uncertainty and recommend additional diagnostic confirmation.

criticalCAUTION

The inference is unstable enough to require explicit caution.

Show the result as decision support only and avoid workflow automation.

blockedSUPPRESSED

The inference is outside the safe publication envelope.

Suppress the clinical answer and require human review or better input.

Infrastructure posture

The specification is public; the managed VetIOS infrastructure remains the commercial product. Partners can implement the runtime signal contract, while production deployments use VetIOS for hosted lineage, outcomes, model cards, network learning, and enterprise/government API access.
