Glossary

Short definitions of the terms used across cards, the registry and the CLI. Exact field rules live in the evidence card protocol and the result status protocol.

Term	Meaning
Claim	A narrow public statement that can be checked against a public source, for example "this documentation page lists these models".
Evidence card	A small JSON record (with an SVG rendering) that documents one check of one claim: protocol, source, hashes, result, boundary and reproduction level.
Protocol (charter)	The written rules of a check, frozen before the result is known: source, method, gate and acceptance rule.
Frozen	Fixed and hashed before the run. A frozen protocol or source is never swapped after seeing the result.
Gate	The pass/fail condition of the protocol.
Claim boundary	The plain-language limit of what the card shows. A pass never extends beyond it.
Source audit	A check that a public source was reachable, had the expected markers and hashed to a recorded value. It is not a check that the source's statements are true.
result_status	The gate outcome: PASSED_UNDER_PROTOCOL, NEGATIVE_RESULT_UNDER_PROTOCOL, BLOCKED_SOURCE, INSUFFICIENT_COVERAGE or REPRODUCED_OUTCOME.
PASSED_UNDER_PROTOCOL	One narrow claim passed the frozen gate. It is not a general quality, safety or compliance statement.
BLOCKED_SOURCE	Access, rights, metadata or lineage were not good enough for a fair verdict. First-class evidence, not a failure to hide.
INSUFFICIENT_COVERAGE	The source exists but is too sparse or uneven for the pre-registered test.
reproduction_level	How far a rerun has confirmed the outcome: not independently reproduced, REPRODUCED_OUTCOME, REPRODUCED_OUTCOME_WITH_SOURCE_BYTE_DRIFT.
Source-byte drift	A rerun reached the same gate outcome, but the fresh source bytes differ from the original ones. Shown as a yellow reproduction chip, never as a failed gate.
verification_level	Verification strength: SINGLE_OPERATOR, SINGLE_OPERATOR_RERUN, INDEPENDENT_RERUN, MULTI_OPERATOR, NOT_EXECUTED.
SINGLE_OPERATOR	One operator ran it. Most public cards are at this level until someone else reruns them.
execution_mode	Provenance: MANUAL_NO_AI or AUTOMATED_AI_ASSISTED. It does not make a result more or less valid.
Operator	The person or handle that ran a check.
Rerun / reproduction attempt	A later run of the same frozen protocol, recorded as its own card that links back to the original.
Registry	docs/registry/evidence_index.json: sanitized metadata and hashes of all cards. It never stores raw payloads.
Raw payload	The downloaded source bytes. Kept locally (raw_payload_committed: false), only hashes are published.
Run root	A local-only folder with standard subfolders for raw data, logs, hashes and reports, created by claimbound run-root.
Artifact-only record	A summary kept in the artifacts catalog that is not (yet) a registry card.
Pseudonymous subject	A confidential method or model referred to by a SUBJ-… identifier; see the pseudonym policy.
