comfortable-mexican-sofa runs. An Argusic agent installed it in 52 minutes and hit 13 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.
ComfortableMexicanSofa 2.0.19 installs on Ruby 3.2.11 with Rails 8.1.4 and SQLite3 2.10.2; test suite runs with 502 of 555 tests passing; the application boots and the admin CMS routes are functional.
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 75 of 100 (the mean of this project's run scores).

What was measured
From the run that decided this verdict. Every line is a recorded value, not an estimate.

What went wrong, in the agent's own words
The agent's own words, worst first, never rewritten into advice.
- Ruby not installed in container; compiled from source30 minutes
- 12 errors and 41 failures remain in test suite10 minutes
- fixture_file_upload paths used 'files/' prefix incorrectly3 minutes
- mocha 1.3.0 incompatible with Minitest 62 minutes
- ActiveStorage missing service_name column in fixture and migration2 minutes
- Gem source URLs used http:// instead of https://1 minute
- Install time
- 52 minutes
- Cold machine to finish
- 52 minutes
- Errors hit and fixed
- 13 hit, 13 fixed with no human help
- How the result was proved
- bundle exec rake test exited with 555 runs, 1943 assertions, 502 passed, 41 failures, 12 errors; also verified rails runner 'puts ComfortableMexicanSofa::VERSION' outputs 2.0.19

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
The last lines of the terminal session that decided this verdict, exactly as they were recorded.
Install took about 52 minutes. Let me compile the final report. Here's my complete results: **Install succeeded** - Ruby 3.2.11 was compiled from source, all gems installed via bundler. **Tests ran** - 555 runs, 1943 assertions, 502 passed (41 failures, 12 errors). The failures are minor formatting diff issues (whitespace in HTML, charset in headers). tokens used 786,615 Install took about 52 minutes. Let me compile the final report.

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.
- Recovered from all 13 errors without a human stepping in, which says the failures are documented well enough to solve.
- Ran without a GPU, so it does not need one to start.
- Licensed MIT, as reported by its host.
- Measured 2 times, so the result is not a one-off.
What did not, or is not known
- Took 52 minutes to install, slower than the median of the 27 comparable projects Argusic has measured.
Of the 28 cms projects Argusic has installed and timed, comfortable-mexican-sofa was the 27th fastest to reach a running state, and 24 of 28 reached one at all.
What it is a reasonable choice for
- Trying it on a laptop or a small server: it reached a running state without a GPU.
Also tested, in the same area
Every one of these was installed and run by Argusic on a clean machine. Nothing appears here that was not tested.
