🚗 WIA-AUTO-021: Vehicle Lightweight Material Standard

The WIA-AUTO-021 standard defines the specifications, testing methods, and computational frameworks for vehicle lightweight materials, including carbon fiber composites, aluminum alloys, high-strength steel, and advanced polymers for automotive applications.

Scope: Material Properties Database: Comprehensive specifications for lightweight materials · Weight Reduction Calculations: Algorithms for calculating weight savings and efficiency gains · Strength-to-Weight Analysis: Performance metrics for material selection · Manufacturing Process Standards: Guidelines for forming, joining, and finishing · Crash Safety Validation: Impact resistance and energy absorption testing · Recyclability Assessment: End-of-life material recovery and reuse protocols

Generate a Phase 1 envelope

This simulator demonstrates the canonical envelope shape defined in the standard's Phase 1 specification. Click the button below to generate a sample envelope; the output is a JSON document that conforming implementations can verify with the reference CLI.

Press “Generate envelope” to produce a Phase 1 sample.

How envelope verification works

Every envelope in this standard is signed with Ed25519 over the canonical JSON form (RFC 8785 JCS). The signature covers all fields except the signature itself; downstream consumers verify by re-canonicalising and re-checking the Ed25519 signature against the publisher's tenant key registered in the WIA-OMNI-API trust fabric.

# Reference verification flow (pseudocode)
canon = jcs_canonicalise(envelope_without_signature)
ok    = ed25519_verify(publisher_pubkey, canon, envelope.signature.value)
assert ok, "envelope signature does not verify"

About this simulator

This page is a Phase 1 envelope simulator for the WIA-AUTO-021 standard. It is intentionally minimal: a working demonstration of the envelope shape, not a production implementation. Production implementations carry signing keys in the WIA-OMNI-API trust fabric, validate against the schema registry, and emit envelopes through the Phase 2 HTTP surface documented under ../api/.

The simulator is provided so that engineers evaluating the standard can see a concrete envelope without standing up a full publisher endpoint. The reference CLI under ../cli/ produces equivalent envelopes from the command line, which is the recommended path for any non-trivial experimentation.

For deeper context, the eBook companion volumes describe the domain rationale for each envelope field. Field choices in this standard are not arbitrary: each field exists to answer a question that downstream auditors, regulators, or interoperability partners would otherwise have to derive from the publisher's narrative documentation.
