K05 assurance architecture

Critical Datacenter Evaluation Range Specification

Direct answer

K05 defines fourteen non-actionable evaluation scenarios spanning IT/OT boundaries, firmware, identity, model and data integrity, sensors, timing, communications, UAS awareness, electromagnetic resilience, power, cooling, restoration, evidence, and authority failure.

Evidence boundary. These records describe architecture, control relationships, test requirements, and legal-source status. They do not certify a facility, authorize a mission, prove deployment, or replace current facility-specific engineering and legal review.

Range-wide safety envelope

  • No production plant or public-network target.
  • No reusable exploit, payload, credential theft, persistence, evasion, engagement, or weapon-construction detail.
  • Effects-disabled or non-damaging substitutes.
  • Independent stop authority and reset evidence.
  • Facility-specific hazards and licensing constraints remain controlling.

Scenario specifications

RNG-01

IT-to-OT boundary pressure

Validate that an assumed-compromised enterprise zone cannot command or silently reconfigure protected OT and safety functions.

Abstract injected condition. synthetic cross-zone access attempts and maintenance-path misuse indications

Pass evidence. boundary blocks or safely mediates the path; alert, evidence, and recovery remain available

Machine record

RNG-02

BMC and firmware trust failure

Evaluate detection, isolation, key revocation, signed recovery, and fleet blast-radius control when management-plane trust is withdrawn.

Abstract injected condition. attestation mismatch, unauthorized configuration state, or simulated signed-artifact failure

Pass evidence. affected management segment is isolated; trusted workloads remain protected; recovery uses verified firmware

Machine record

RNG-03

Workload identity compromise

Evaluate short-lived identity revocation, session termination, lateral-movement containment, and service continuity.

Abstract injected condition. synthetic credential replay or identity-policy violation

Pass evidence. identity is revoked within target time; unaffected functions continue; decision and rollback evidence is complete

Machine record

RNG-04

Model and data poisoning

Evaluate provenance checks, disagreement detection, drift thresholds, action suspension, and clean model/data restoration.

Abstract injected condition. controlled corruption of approved evaluation data or model metadata

Pass evidence. high-consequence actions suspend before unsafe execution; provenance gap is recorded and restored

Machine record

RNG-05

Sensor conflict and adversarial input

Evaluate multi-modal disagreement, sensor-health weighting, classification uncertainty, and non-destructive degraded response.

Abstract injected condition. synthetic inconsistent radar, optical, thermal, acoustic, or access-control observations

Pass evidence. single-source error cannot trigger destructive action; system degrades to tracking, delay, and authorized notification

Machine record

RNG-06

Timing integrity loss

Evaluate path-delay anomaly detection, clock-health scoring, holdover, safe process behavior, and trusted-time restoration.

Abstract injected condition. controlled timing offset, jitter, source loss, or authentication failure

Pass evidence. protection functions reject unsafe time-dependent decisions and remain in approved state

Machine record

RNG-07

Communications denial and partition

Evaluate decentralized safe operation, local authority, stale-command rejection, reconciliation, and evidence continuity during network partition.

Abstract injected condition. loss or degradation of selected inter-zone and external communications

Pass evidence. critical functions continue or reach safe state; no stale external command is accepted

Machine record

RNG-08

UAS intrusion awareness

Evaluate detection, tracking, classification uncertainty, airspace-restriction data, authorized responder routing, and authority separation.

Abstract injected condition. synthetic or range-approved uncrewed-aircraft tracks and sensor disagreement

Pass evidence. system maintains track and evidence without executing unauthorized interference or destructive action

Machine record

RNG-09

Electromagnetic disruption

Evaluate degradation of sensors, communications, timing, edge compute, and restoration assets under approved non-damaging interference simulation.

Abstract injected condition. laboratory or simulated component degradation within certified range limits

Pass evidence. essential functions retain protected modes; failed components are identified; no test energy escapes the range

Machine record

RNG-10

Power load rejection and islanding

Evaluate grid separation, load shedding, reactor or generation response models, UPS/storage behavior, essential cooling, and resynchronization.

Abstract injected condition. hardware-in-the-loop or digital-twin load step and grid-state transition

Pass evidence. safety limits remain satisfied; essential functions persist; resynchronization follows approved sequence

Machine record

RNG-11

Cooling telemetry corruption

Evaluate physics-aware detection and independent protective behavior when supervisory cooling data is wrong or unavailable.

Abstract injected condition. synthetic sensor bias, data freeze, or supervisory-command conflict

Pass evidence. independent sensing prevents unsafe command; essential cooling remains within tested envelope

Machine record

RNG-12

Clean-room recovery and reinfection resistance

Evaluate dependency-aware restoration, credential rotation, evidence preservation, artifact attestation, and return-to-service gates.

Abstract injected condition. declared compromise state followed by controlled restoration exercise

Pass evidence. restored components attest to approved state; reinfection path is blocked; evidence chain remains intact

Machine record

RNG-13

Evidence ledger integrity

Evaluate detection and recovery when decision receipts, logs, hashes, or incident records are missing, reordered, stale, or contradicted.

Abstract injected condition. controlled evidence omission, hash mismatch, or chronology conflict

Pass evidence. readiness automatically degrades; claim is suspended; authoritative evidence chain is restored or gap remains public

Machine record

RNG-14

Authority package failure

Evaluate automatic stop, minimization, notification, and evidence preservation when mission authority expires, target scope conflicts, or critical-outcome risk emerges.

Abstract injected condition. synthetic authority revocation, asset-scope mismatch, deconfliction conflict, or outcome-threshold breach

Pass evidence. external action does not proceed or ceases; authority and review records capture the event
