Slot: attestationStorageUri

URI indicating where this signed attestation is publicly stored or retrievable. No universal standard for attestation storage location was established in SLSA v1.0; Sigstore and VCS-embedded storage are two common approaches. Explicitly recording this URI addresses the storage ambiguity identified as a significant adoption barrier: practitioners reported uncertainty about where generated attestations should be stored (Tamanna et al., 2024, LF.1).
