Test-Vector Verification Evidence

Date: 2026-07-14
Scope: Specification fixtures only; not release evidence.

• Every JSON Schema, manifest, envelope, and case file parsed successfully with jq.
• Canonical Workstation bytes were produced with jq -cS, including its single trailing newline.
• Canonical SHA-256: e3c8a7f5ac9c0ad1ebc29c739f32dbd3c533d8ac7378b76cca12f30a5ebd5e10.
• The 64-byte detached signature verified successfully with the committed Ed25519 test public key.
• The private test key was generated only for this vector and deleted after signing.
• git diff --check passed after the fixture additions.
• Automated validation using jsonschema Draft 2020-12 and cryptography passed: Schema fixtures: PASS (Draft 2020-12), Artifact signatures: PASS (4/4), Signature negative cases: PASS (4/4), and Compatibility cases: PASS (12/12).

This proves the current structural schemas, all four test-only artifact signatures, negative signature cases, and compatibility cases are internally consistent. It does not approve the signing policy, exercise real payload objects, or validate any production artifact.
