@grayhaven/nerve-interop

Deterministic, loss-aware interoperability primitives for Grayhaven Nerve.

This package deliberately does not certify a harness, reproduce licensed standards text, supply normative acceptance values, implement an OPC UA transport, or parse official VEC XML. It provides four bounded building blocks:

• standards profiles that identify exact authorities, revisions, scope, applicability, parameter sources, reviewers, and evidence layers;
• a normalized structured VEC 2.2 subset adapter for connectors, pins, terminals, seals, and point-to-point wires;
• transport-neutral OPC UA 40570 v1 job/result mappings for its initial single-core, single-layer cut/strip/crimp/seal scope; and
• caller-parameterized automation-data and high-voltage design-readiness evaluations.

Important scope limits

Vec22SubsetDocument is an interchange DTO, not an XML parser and not proof of VEC conformance. The caller owns the official VEC XML XSD/ontology/SHACL toolchain and supplies validator identity, version, pass state, and report hash. Unknown extensions carry their source path and either lossless JSON or a raw artifact reference/hash so the adapter does not silently discard them. The public version and semantic-validation context is maintained by prostep ivip in the VEC 2.2.0 specification and compliance-test guidance.

The OPC mapping follows the public scope of OPC 40570 v1.0.0, published 2025-04-01: https://reference.opcfoundation.org/specs/OPC-40570. It is not an OPC UA client, binding, certificate, assembly protocol, or end-of-line tester protocol. It never invents a cut, strip, terminal, seal, or process value.

Automation findings evaluate only requirements selected by the caller. A profile may cite DIN 72036 or another source, but a result is not a DIN or other standards-conformity determination. High-voltage evaluation compares only caller-declared voltage domains against facts present in HIR. HIR does not currently establish HVIL function, physical segregation/clearance, or shield grounding, so those declarations remain unassessed. No hipot voltage, ramp, dwell, leakage, clearance, or insulation-resistance threshold is synthesized. The current publication identity for the automation-oriented design standard is DIN 72036:2026-04; this package contains none of its licensed rules.

Standards profiles may contain references and caller-controlled identifiers; they are not a home for copied tables, standard prose, acceptance values, or claims such as “certified” or “compliant.”
