CRS
Section 1 of 8

Identity

Establish what model is deployed, by whom, at what risk level, and with what consequence weight.

Section 2 of 8

Maturity

Document the IMS level and the evidence artifacts that substantiate it. IMS is evidence, not assertion — Rule 2.

0 — Opaque 5 — Continuous
Section 3 of 8

Circuit Inventory

Describe what the model does, what it takes as input, and what decisions it produces. This section informs red team scoping (Section 6) and compensating controls (Section 7).

If IMS ≤ 1, circuits may not be nameable yet — describe the functional areas the red team should probe.
Section 4 of 8

KPI Baseline

Six KPIs must be baselined before production (Rule 4). ACFR is Rule 7-linked — ACFR ≥ 1 in any model-quarter forces Red band independently of CRS. ACFR is a count of P1 safety-circuit bypasses, not a ratio.

ⓘ ACFR (KPI 1) is required. Name the remaining five KPIs to match your deployment context — common choices include accuracy/precision/recall, fairness disparity index, stability (drift rate), data quality score, and latency.
Section 5 of 8

Vendor Transparency

The Vendor Transparency section is not optional (Rule 8). For Category A models, complete this as an internal engineering attestation signed off by your ML lead.

Section 6 of 8

Red Team Record

Rule 6 requires circuit-aware (not behavioural-only) red team exercises. Cadence: semi-annually for High/Critical-tier, annually for Moderate-tier, not required for Low-tier.

Section 7 of 8

Compensating Controls

Required for Red and Purple band systems, and for any system below its IMS floor. Document the controls that bound the risk while interpretability evidence is being gathered.

Red band: 180 days from sign-off date. Target: Amber band or decommission.

Lifecycle

Registry entries must be retained for a minimum of three years from deployment (Rule 10). Document the retention expiry date.

Must be ≥ 3 years from deployment date. Rule 10.
