- Fix is_cbor_map_prefix to cover full CBOR map range (0xa0..=0xbf) - Remove SCALE Encode/Decode impls for VersionedAttestation to avoid consuming all remaining input on decode - Remove ambiguous 0x01 prefix fallback in from_bytes - Change to_bytes to return Result instead of panicking via or_panic - Add report_data_payload binding validation in verify_with_time
- Restore Encode/Decode impls for VersionedAttestation (needed by CertSigningRequestV2), with a 10 MiB size limit to prevent OOM on untrusted input - Add size check in from_bytes for direct callers - Document that VersionedAttestation must be the last field in SCALE containers due to the consume-all-remaining decode strategy - Fix prek formatting

/var/run/dstack.sockin dstack-k8s needs to return a verifier-visible payload preimage for report_data, but this is better modeled as a platform-specific attestation quote variant than as a new top-level versioned envelope.Validation
