Health & Supply Chain Composite

Zero-trust device management asks 'is this device's identity valid?' Supply-chain attestation asks 'where did this device come from?' Trust-slope anomaly detection asks 'is this device behaving consistently with its history?' These are three separate disciplines today. This article introduces a unified composite primitive that integrates governance-chain integrity with supply-chain provenance into a single fleet-health observation.

Health monitoring evaluates governance chain integrity continuously. Compromised credentialing authorities, broken authority chains, and revoked credentials all surface as health-monitoring events.

Health monitoring detects anomalies in trust slope — the rate at which trust evaluations are changing across the mesh. Sudden trust-slope changes can indicate emerging compromise, adversarial activity, or genuine operational shift.

Credential revocations propagate through the mesh; health monitoring evaluates the propagation completeness and identifies revocation gaps.

Health monitoring includes physical-unclonable-function (PUF) challenge-response verification of unit hardware identity. Compromised, replaced, or counterfeit hardware fails the PUF verification structurally.

Health monitoring includes Software Bill of Materials (SBOM) attestation. Each unit's software composition is credentialed; deviations from declared SBOM enter as health-monitoring events.

Health monitoring includes tamper-evident-seal verification for physical units. Compromised physical seals enter as credentialed monitoring events; affected units can be flagged or quarantined structurally.

Health monitoring composes per-unit health into composite fleet health assessment. The fleet-level assessment identifies systemic patterns: simultaneous degradation, geographic-specific issues, supply-chain-correlated issues.

Health monitoring operates within a zero-trust device-management framework. Each unit's continued admissibility depends on continuous health verification; admissibility lapses produce structural exclusion.

Health monitoring integrates with regulatory compliance regimes. Compliance-relevant health observations feed regulatory reporting; regulatory updates feed monitoring requirements.
