DataCite. Instrument DOIs from the NUANCE registry (nuance-datacite) are recorded in metadata,
provenance and the seal manifest; nuscope cite builds dataset-DOI metadata linked to the instrument
(IsCollectedBy), the seal and the creators' ORCID iDs, and --draft registers a draft DOI.
Acquisition dates are normalized to ISO 8601 for every vendor.
Studio shows the instrument DOI and any dataset DOI.
Shared identity. Signing uses the researcher identity of EMDataBridge (name, validated ORCID iD,
Ed25519 key), shared with NUScope-TOMO and NUANCE-MCP. Keys made by 0.3 are imported; files signed by 0.3
still verify. The person in provenance comes from the identity.
NUANCE-MCP plugin. Every acquisition is saved as a sealed, signed .h5; new tools nuscope_describe,
nuscope_verify, nuscope_history, nuscope_analyze, nuscope_list, nuscope_identity.
nuscope keys untrust; one-line CLI errors instead of tracebacks.
Integrity. SHA-256 hash-chained provenance; a seal in every saved file; Ed25519 signatures,
countersigning and trust; verification on every read; nuscope verify | sign | keys.
Save as .h5.
