DSSE Revision Decision

Decision ID: DECISION-MIRROR-001 Status: DEFAULT-APPROVED Effective Date: 2025-12-06 48h Window Started: 2025-12-06T00:00:00Z

Decision

The Mirror bundle DSSE envelope format follows the in-toto v1.0 specification with StellaOps extensions for offline verification.

Rationale

  1. in-toto v1.0 is the industry standard for software supply chain attestations
  2. DSSE (Dead Simple Signing Envelope) provides a clean JSON wrapper
  3. Existing tooling (cosign, rekor) supports this format
  4. Aligns with Evidence Locker DSSE patterns already implemented

Specification

{
  "payloadType": "application/vnd.in-toto+json",
  "payload": "<base64-encoded-in-toto-statement>",
  "signatures": [
    {
      "keyid": "<key-id>",
      "sig": "<base64-signature>"
    }
  ]
}

StellaOps Extensions

  • _stellaops.revision: Bundle revision number
  • _stellaops.timestamp: ISO-8601 UTC timestamp
  • _stellaops.merkleRoot: SHA-256 Merkle root of bundle contents

Impact

  • Tasks unblocked: ~5
  • Sprint files affected: SPRINT_0150_mirror_dsse

Reversibility

To change the DSSE format:

  1. Propose new format in docs/modules/mirror/dsse-proposal.md
  2. Get Security Guild sign-off
  3. Update all affected sprint files
  4. Ensure backward compatibility for existing bundles
