ACR Runtime Control Plane Standard v1.0.1
The normative specification defining required control outcomes, decision semantics, evidence properties, and conformance criteria. Implementation-independent, testable, and auditable.
Three cumulative conformance levels.
- Action logging
- Decision logging
- Correlation identifiers
- Agent identity and purpose records
- Policy decision records
- Audit export capability
- Minimum retention enforcement
Does not require mandatory pre-execution blocking for all protected actions. The conformance claim must identify every execution path outside enforcement scope.
- Mandatory pre-execution control
- Deny-by-default behavior
- Identity and purpose binding
- Policy enforcement at Execution Boundary
- Approval gating for escalated actions
- Executor-side verification
- Containment with kill path
A protected action without valid control-plane authorization must fail. The executor must reject replayed, tampered, and unauthorized execution requests.
- All Level 2 capabilities
- Enforcement at all three Boundaries
- Full four-state decision model (ALLOW/DENY/MODIFY/ESCALATE)
- Drift detection with thresholded response
- Graduated containment
- Quarterly containment testing
- Tamper-evident high-risk logging
- Full STRIKE mapping
- Formal escalation authority matrix
- Safe-state definitions
- Audit-ready evidence bundles
Verification requires controlled tests demonstrating all four decision outcomes, reconstructable incident records, drift conditions triggering documented response tiers, and on-schedule kill-switch test records.
ACR controls mapped to five governance frameworks.
23 control mappings across 6 pillars with 100% pillar coverage.

ACR Standards Crosswalk - 23 Control Mappings Across 6 Pillars
The ACR Runtime Control Plane Standard maps 23 controls across six pillars to five governance frameworks: ISO/IEC 42001, NIST AI RMF, NIST CSF 2.0, ISO 27001, and NIST SP 800-207 Zero Trust Architecture.
