arnis runs. An Argusic agent installed it in 12 minutes and hit no errors on a clean machine with no GPU, and the whole session was recorded.
Arnis 3.2.0 builds from source, passes all 1189 unit tests, and generates valid Minecraft Java Edition Anvil worlds from sample OSM fixture data via the CLI.
What the agent ended up with on a clean machine, in its own words. How this is measured
Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 100 of 100 (the mean of this project's run scores).
At a glance
Subject data from GitHub, linked at the top of this page, refreshed . Test data by Argusic (CC BY 4.0); every number links to a run page with the full log, the recording, and their sha256 hashes.
What was measured
From the run that decided this verdict. Every line is a recorded value, not an estimate.
- Install time
- 12 minutes
- Cold machine to finish
- 19 minutes
- Errors hit and fixed
- 0 hit, 0 fixed with no human help
- How the result was proved
- cargo test --no-default-features exited 0, 1189 passed, 0 failed, 16 ignored; ./target/release/arnis --version printed 'arnis 3.2.0'; ./target/release/arnis --file tests/fixtures/sample.osm --output-dir /tmp/test_arnis_world --mode geo-only completed successfully producing a valid Minecraft Java Anvil world with gzip-NBT level.dat (4773 bytes decompressed, root tag compound) and region file r.0.0.mca

What was not measured
The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.
- Peak GPU memory
- this ran on a CPU machine, so there was no GPU to sample
- Behaviour over a long run
- each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load
The end of the recording

Replay the whole session, every command from a clean machine to this point.
How it was tested
One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.
Strengths and limits
Measured facts, not opinions. How this is written.
What went well
- Reached a running state on a clean machine, with the session recorded.
- Installed in 12 minutes.
- Nothing broke on the way: zero errors between clone and running.
- Ran without a GPU, so it does not need one to start.
- Licensed Apache-2.0, as reported by its host.
What did not, or is not known
- Measured once so far. A single attempt shows it can run, not that it runs reliably.
What it is a reasonable choice for
- Trying it on a laptop or a small server: it reached a running state without a GPU.
- Following its own README: the documented path worked with nothing to fix.

[](https://argusic.com/subject/arnis)Questions
- Does arnis run?
- Yes. arnis runs. Argusic installed and launched it on a clean machine in 12 minutes, hitting 0 errors on the way, and recorded the session.
- How did Argusic test arnis?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit fc19146b3f72. One attempt is recorded, and the full method is on the methodology page.
- What did it cost to test arnis?
- The run that produced this verdict cost $0.05: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does arnis take to install?
- 12 minutes in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
- Does arnis need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing arnis?
- Nothing did, in the recorded run: zero errors between clone and running.
- Where is the evidence for arnis?
- The recorded run is on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
