What does Annex IV technical documentation look like?

An example, for a fictional company called Harbrook: the technical documentation that Complipath (complipath.io) opens as one document for a high-risk AI system, in Annex IV's own nine points. Each point is marked Written, Draft or Not written yet, its sources stand under it and the whole document downloads as PDF or Word.

Whose document this is

Harbrook is invented.
In this example it builds Applicant sorter, which sorts incoming job applications for an employer's recruiters to review, and sells it to employers.
Its confirmed classification is high-risk under point 4(a) of Annex III, and Harbrook is its provider.

Article 11(1) and Annex IV of Regulation (EU) 2024/1689 set out the technical documentation of a high-risk AI system.
Annex IV lists the information it contains at least, as applicable to the system.

How the document opens

The title, Technical documentation, with a line under it counting the points that are written, draft and not written yet, of the nine.
The head of the page: Harbrook · Applicant sorter on one side and Article 11 · Annex IV on the other.
Two buttons, Download as PDF and Download as Word. Both files carry the same points, statuses and sources in the same order. The PDF numbers its pages.
Each point opens with its citation and, as its heading, its own words from Annex IV: the opening line for points 1 and 2, the whole point for points 3 to 9.
In the app the button that opens it, View full document, appears for a system whose confirmed classification calls for Annex IV documentation.

How a point gets its status

Written: every part of the point holds text a person wrote or a reviewer confirmed.
Not written yet: no part of the point holds any text.
Draft: everything in between. A part may still be empty, or hold text nobody has made their own yet: a model's draft or a sentence filled in from the register.
The status is counted from which parts hold text, never judged from the text itself. A file attached to a point is named in its sources and is never counted as text.

The nine points, as the example shows them

The heading column is Annex IV's own text, as the document prints it. The last column is what stands under each point in this example, with the source lines in the app's wording.

Example · Technical documentation for Applicant sorter (fictional company)
Point	Heading in the document	Status	Under it in this example
point 1 of Annex IV	1. A general description of the AI system including:	✓ Written	Sources: Your answer · File: product-overview.pdf — Head of product, (date)
point 2 of Annex IV	2. A detailed description of the elements of the AI system and of the process for its development, including:	Draft	One part is open: point 2(f) of Annex IV · Not written yet, with the link Answer the questions · Risks and how you handle them. Sources: Your answer · Draft from: Purpose · Reviewed by Head of product on (date) · Draft from your answers · Your edit of a draft
point 3 of Annex IV	3. Detailed information about the monitoring, functioning and control of the AI system, in particular with regard to: its capabilities and limitations in performance, including the degrees of accuracy for specific persons or groups of persons on which the system is intended to be used and the overall expected level of accuracy in relation to its intended purpose; the foreseeable unintended outcomes and sources of risks to health and safety, fundamental rights and discrimination in view of the intended purpose of the AI system; the human oversight measures needed in accordance with Article 14, including the technical measures put in place to facilitate the interpretation of the outputs of AI systems by the deployers; specifications on input data, as appropriate;	✓ Written	In Who oversees it, under point 2 of Annex IV. Sources: Reviewed by Head of product on (date)
point 4 of Annex IV	4. A description of the appropriateness of the performance metrics for the specific AI system;	Not written yet	Not written yet. Nothing in your documentation answers this point so far. Link: Answer the questions

point 6 of Annex IV	6. A description of relevant changes made by the provider to the system through its lifecycle;	✓ Written	Sources: Your answer
point 7 of Annex IV	7. A list of the harmonised standards applied in full or in part the references of which have been published in the Official Journal of the European Union; where no such harmonised standards have been applied, a detailed description of the solutions adopted to meet the requirements set out in Chapter III, Section 2, including a list of other relevant standards and technical specifications applied;	Draft	Sources: Draft from your answers

A detailed description of the system in place to evaluate the AI system performance in the post-market phase in accordance with Article 72, including the post-market monitoring plan referred to in Article 72(3).	Not written yet	Not written yet. Nothing in your documentation answers this point so far. Link: Answer the questions

Where each point is answered

The document regroups the four sections of the documentation workspace by Annex IV's points. The sections, in order: What the system does · The data it uses · Risks and how you handle them · Who oversees it.
A section reviewed or written by hand as a whole stands once, under the first point it answers, and its later points say where it is. That is why point 3 reads “In Who oversees it, under point 2 of Annex IV.”
An open point links to the questions of its section. In the PDF and the Word file a link cannot be pressed, so the point reads “Nothing in this documentation answers this point yet. It is answered in Complipath, under Documentation.”

What this example leaves out

The text under each point. A real document prints it, drafts included and marked as such; Harbrook has none, so this example shows headings, statuses and sources only.
Names and dates. Where the app prints a reviewer's or an uploader's name, this example prints a role, and where it prints a date, it prints (date).
A model at work. The Draft points stand for text a model drafted earlier from the workspace's own facts and answers, which stays Draft until a person edits it or reviews the section. Opening and downloading the document calls no model. Rules decide. AI only drafts. A person confirms.
Every page and file ends with the line “A self-assessment made with Complipath. Not a certification or a legal opinion.”

Questions

Is Harbrook a real company?

No. Harbrook and Applicant sorter are invented for this page, and so are the file names and the roles that stand where a person's name would. What is real is the shape: Annex IV's nine points in order, the three statuses and the source lines under each point, in the words the app prints.

Why is point 2 Draft when most of it is written?

Because a point is Written only when every part of it holds text a person wrote or a reviewer confirmed. Point 2 of Annex IV has eight lettered parts. In this example one is still empty and two hold drafts nobody has made their own, so the whole point reads Draft until they do.

Does attaching a file complete a point?

No. A file attached to a point is named in its sources and stays a file: it is never counted as text, and the product never says that attaching one meets a requirement. A point is Written only when its text is there, and Not written yet when no part of it holds any.

Which plan includes the full document?

Every plan, as the app lists it. The button View full document appears on the Documentation page for a system whose confirmed classification calls for Annex IV documentation, and the same points download as a PDF or a Word file. Writing the text is done in the documentation workspace, section by section.
