Human oversight verification protocol (PR-14-OVR)

PR-14-OVR v1.0 is built from prEN 18229-1Enquiry, prEN 18229-3Draft, Art. 14 and Art. 26 of Regulation (EU) 2024/1689.

Scope

The protocol covers a high-risk AI system whose provider designs human oversight measures under Art. 14, and the deployment of such a system whose deployer implements those measures under Art. 26. The obligations start from the Annex III application date 2027-12-02Deferred for systems classified under Annex III and from the Annex I date 2028-08-02Deferred for systems classified under Annex I.

On the provider side the protocol covers the seven testable elements of the Art. 14 obligation record: the human-machine interface tools, monitoring of an injected anomaly, the measure against automation bias, the interpretation tools, the decision not to use and the override or reversal of an output, the stop function and its safe state, and the two-person verification for Annex III point 1(a) biometric identification systems. On the deployer side the protocol covers five testable elements of the Art. 26 obligation record: use within the instructions for use, implementation of the provider's deployer-side measures, the authority of the assigned persons, the support available to them, and the suspension of use.

The protocol does not cover log completeness, decision reconstruction or log retention under Art. 12 and Art. 26(6); PR-12-LOG v1.0 covers those elements. The protocol does not cover the relevance and representativeness of input data under Art. 26(4); PR-10-BIAS v1.0 covers that element. The protocol records the documentation and process elements of both articles as inputs and does not test them. The protocol does not decide whether a system falls under Annex III point 1(a) or whether the Art. 14(5) exception for law enforcement, migration, border control or asylum applies; that determination rests with the provider, the deployer and their counsel.

    [prEN 18229-1, enquiry stage, clause on event record content]

The log extract lists each oversight action as one event. Times are relative to the campaign start so that the extract carries no calendar date. The layout below is synthetic.

    [Regulation (EU) 2024/1689, Art. 14(3)]

38. Classify each finding by the Art. 14 or Art. 26 element it affects.

    Record Finding register: finding id, article element, case ids, severity as stated by the provider's risk file

    [AIAssuranceLabs procedure]

    Record Provenance block on each output: protocol version, system version, input document list

    [AIAssuranceLabs procedure]

Thresholds and criteria

Regulation (EU) 2024/1689 sets no numeric performance threshold for human oversight. The one count in the covered articles is in Art. 14(5): at least two natural persons separately verify and confirm a biometric identification before the deployer acts on it. Every other pass criterion in this protocol is a binary observation taken from the article text, or a provider-declared value the protocol records and compares.

The six-level hierarchy from the obligation mapping applies as follows.

1. No harmonised standard is cited in the Official Journal for Art. 14 or Art. 26 as of the anchor date, so level one is empty and no presumption of conformity attaches to any result of this protocol.
2. prEN 18229-3Draft is the JTC 21 draft for human oversight; no text is public, so the protocol takes from it the categories of measures a verification covers (steps 4 and 16) and takes no criterion from it. prEN 18229-1Enquiry is under enquiry and supplies the expected content of the log event that records an oversight action (steps 11, 30 and 35).
3. No ISO/IEC standard or technical report in data/standards.json supplies a human-oversight pass criterion; level three is not used.
4. No Commission guideline or code of practice in data/standards.json addresses Art. 14; level four is not used.
5. NIST AI RMF 1.0Published names accountability and transparency as trustworthiness characteristics but sets no oversight criterion; level five is not used.
6. The provider justifies each oversight measure against the risks, the level of autonomy and the context of use, as Art. 14(3) requires. Step 7 records that justification and step 37 checks that each entry names all three factors.

Outputs

Every artifact carries the provenance block from step 43. The deliverable specifications live on the deliverables page; the scope limits of the service are stated on what we cannot do.

Limitations

The protocol shows that the oversight measures work in a scripted campaign on the tested system version and deployment configuration. The protocol does not show that the assigned persons oversee the system effectively during live use, because live use varies in load, case mix and attention; Art. 14(1) places that duty on the design for the whole period of use, and a repeat of the protocol after each change to the system or its interface is the process element recorded in the Art. 14 obligation record.

The protocol records the assignment record under Art. 26(2) and does not assess whether the named persons hold the necessary competence and training; a document and a repeated activity show those elements, and a test does not.

The protocol takes the categories of oversight measures from prEN 18229-3Draft, whose text is not public, and takes the log event expectations from prEN 18229-1Enquiry, which is under enquiry. A change to either document at a later stage changes the citations in steps 4, 11, 16, 30 and 35 and produces a new version of the protocol.

The protocol does not show log completeness, decision reconstruction or retention; PR-12-LOG v1.0 covers Art. 12 and Art. 26(6). The protocol does not show the relevance or representativeness of the input data; PR-10-BIAS v1.0 covers Art. 26(4).

The protocol does not decide whether a system is a remote biometric identification system under Annex III point 1(a), or whether the Art. 14(5) exception for law enforcement, migration, border control or asylum applies to a deployment. Steps 28, 29, 34 and 42 run only where the provider or deployer states that Art. 14(5) applies.

For a deployer that also performs a fundamental rights impact assessment under Art. 27, the human oversight verification report supplies the description of the implementation of oversight measures that Art. 27(1)(e) asks for. The application date of that assessment is an unsettled point.
