-title: Verify your TRACE implementation
+title: TRACE conformance suite
description: Run this suite against a TRACE record to see which conformance level it reaches, and produce a report anyone can reproduce from the record and the suite version.

-# TRACE Test Suite
+[04 · Evidence: can a third party verify all of it offline, years later?](https://agentrust-io.com/#chain)
-Check a TRACE record, inspect the findings, and produce a reproducible conformance report. The suite checks the record and supplied evidence; a passing report does not establish that an entire implementation meets every requirement of the [TRACE specification](https://trace.agentrust-io.com).
+# Score a TRACE record against the specification
-The [eight modules](docs/modules.md) cover envelope, signature, runtime, policy, appraisal, transcript, transparency, and provenance checks. Read the [limitations](LIMITATIONS.md) to interpret what each result establishes.

-!!! tip "TL;DR"
- - `verify` answers a question for the person running it. `report` produces an artifact for somebody who was not there.
- - `report` runs every level up to `--max-level`, because the useful answer is the highest level a record reaches, not whether it cleared the level someone happened to pick.
- - The HTML report is self-contained: no scripts, no fonts, no external CSS, no badge service, nothing fetched when it is opened.
- - The report is not evidence, and it says so on its face. It carries the record digest, the suite and library versions, and the command to reproduce the result.

-```bash
-pip install agentrust-trace-tests
-trace-tests verify --record path/to/trust-record.jwt --level 1

-## A report you can hand to someone else

-trace-tests report --record trust-record.json --html report.html --json report.json --badge trace.svg

+The suite checks one record and the evidence supplied with it, reports the highest conformance level reached, and writes a report anyone can reproduce from the record digest and suite version. A passing report does not establish that an entire implementation meets every requirement of the [TRACE specification](https://trace.agentrust-io.com).
-Use `--fail-under 1` to gate CI on a level. Without it the command always exits `0`, which is what you want when you are producing an artifact rather than enforcing a threshold. `report.json` is stable under `schema: agentrust-io/trace-tests/report/1` for dashboards and CI.

-CLI reports add an independently versioned `obligation_accounting` member for a
-bounded three-obligation pilot: `TR-APR-001`, `TR-POL-003`, and `TR-SCA-002`.
-The rows and findings come from one execution snapshot, and the report refuses
-an incomplete pilot matrix. This does not claim complete TRACE accounting.
-The extension treats `report/1` as additively extensible; compatibility with
-consumers requiring the exact historical top-level key set is not established.
-See [Known limitations](LIMITATIONS.md) for the trust and replay boundary.

-A conformance report that looks authoritative and cannot be checked is the same shape of thing as a control plane writing its own log. So the report tells a reader who does not trust the sender to go and check the record instead, and gives them what they need to do it.

+!!! tip "TL;DR"
+ [agentrust-trace-tests](https://pypi.org/project/agentrust-trace-tests/) 0.5.1 (Apache-2.0) runs eight modules against a record on your machine and writes a report carrying the record digest, the suite version and the command to reproduce it. A pass describes the record and says nothing about the agent, and TR-RTE checks the shape of attestation fields without verifying a quote against AMD or Intel roots.
