Generate your EU AI Act evidence from the test run, not a doc sprint

Annex IV asks you to document the testing you did for accuracy and robustness. For a well-tested agent, that is data you already have as test runs. Generate the draft from the run, tied to the commit.

The EU AI Act gives you a documentation obligation that arrives long before any auditor does, and most teams plan to satisfy it with a doc sprint they have not scheduled yet.

If you are building an AI system that lands in the high-risk category under the EU AI Act, Annex IV is the part that turns into homework. It lists the technical documentation you are expected to keep on file: a description of the system, its intended purpose, the development process, and, crucially, the testing you did to establish accuracy and robustness. Read it as an engineer, and a pattern jumps out. A lot of Annex IV is asking you to write down things that, for a well-tested agent, you already know. You just know them as test runs and CI logs, not as a document.

The usual failure mode is to treat the documentation as a separate artifact assembled after the fact. Someone exports dashboards, screenshots a few test results, writes prose around them, and pastes in a date. The doc describes a system, but it is not tied to a specific build. By the time anyone reads it, the code has moved on. That gap between "what we tested" and "what we wrote down we tested" is where compliance documentation quietly rots.

The overlap is real, and it is narrow

I want to be precise about the overlap, because overstating it is exactly the kind of thing that gets a team in trouble.

A behavioral test suite produces evidence that maps onto parts of a few Annex IV-adjacent articles:

  • Article 15 (accuracy, robustness, cybersecurity): your pass rates, your latency and cost ceilings, your adversarial and edge-case tests. This is the strongest fit. Accuracy and robustness testing is, almost definitionally, what a regression suite does.
  • Article 12 (record-keeping): a test run is a record. If it is reproducible and tied to a commit, it is a good record.
  • Article 13 (transparency): your assertions about what the system outputs and refuses to output are part of the transparency story.
  • Article 9 (risk management): your gates encode risk controls. A piiFailuresMax: 0 gate is a written-down risk decision.
  • Article 10 (data governance): partial at best. A test suite says very little about training data lineage. Do not pretend otherwise.

That list is the honest boundary. A test run is not a risk management system. It is one input to one. It says nothing about your data provenance, your human oversight design, or your post-market monitoring plan. Anyone who tells you a CLI makes you "compliant" is selling something. Compliance is a legal determination involving a conformity assessment and, for many high-risk systems, a notified body or internal assessment process. A test runner is not an auditor and cannot become one.

Generate the evidence, do not reconstruct it

Here is the argument, stated plainly. The accuracy and robustness evidence Annex IV wants is the same data your CI gate already computed. So generate the documentation draft from the test run itself, at the moment the run happens, tied to the commit that produced it. Do not reconstruct it from memory three months later.

This is the same discipline as not duplicating state in code. The test run is the source of truth. The compliance document should be derived from it, not maintained as a parallel hand-written copy that drifts.

KindLM's --compliance flag does exactly this and nothing more. It takes the gate results from a run and emits a Markdown documentation draft that maps those results to the selected articles above, then appends a SHA-256 hash over the content for tamper evidence. It is explicitly labeled as not legal advice and not a conformity assessment. What it gives you is narrow but useful: a versioned, tamper-evident, reproducible evidence artifact tied to one specific commit. That is a defensible starting point for the technical file, and it is a much better starting point than a blank page the week before a review.

What the run looks like

Here is a suite that encodes two risk controls as gates: a minimum pass rate and zero tolerance for PII leakage. The same run that fails CI on a regression is the run you generate the draft from.

          - "123-45-6789"

gates:
  passRateMin: 0.98
  piiFailuresMax: 0

defaults:
  repeat: 3

Note the repeat: 3. A single pass tells you little about robustness; running each case several times and gating on the aggregate pass rate is closer to what "robustness testing" should mean, and it is a more honest number to put in a document.

Then the run that gates CI is the run that produces the draft:

kindlm test --compliance

Exit code 0 means every gate passed and you have a clean draft tied to this commit. Exit code 1 means something regressed, and you have evidence of that too, which is arguably the more important record to keep.

Why the hash and the commit matter

The two properties that make this worth doing are reproducibility and tamper evidence.

Reproducibility comes from the config plus the commit. The YAML is in your repo, the run is pinned to a git SHA, and anyone can re-run it. A reviewer asking "how do you know your agent does not leak SSNs" gets a config they can read and a command they can run, not a screenshot they have to trust.

Tamper evidence comes from the SHA-256 hash over the draft content. It does not prove the test results are correct. It proves the document has not been altered since it was generated. That is a modest claim, and it is the right modest claim. It lets you say a specific document corresponds to a specific run, and it lets anyone detect after-the-fact editing.

On timing: the high-risk obligations under the Act phase in over the next couple of years rather than all at once, with later deadlines for systems already on the market. I am deliberately not quoting exact dates here, because the staging is the kind of detail worth checking against the current official text rather than a blog post. The engineering point holds regardless of the precise date: the documentation is easier to produce continuously than to reconstruct under deadline.

The takeaway

The technical file is not where you want to discover that your "robustness testing" was a few manual runs nobody recorded. If your agent is worth shipping into a high-risk setting, you are already running behavioral tests, or you should be. Wire the documentation draft to that run so the evidence is generated, versioned, and hashed at the moment it is true, instead of being narrated later from memory. It will not make you compliant, and no tool can. It just means that when the question comes, your answer is a commit hash and a command, not a doc sprint.
