How results are judged

Task: ARC-AGI-3
Metric: RHAE (%), higher is better
Baseline: Random agent: 0
Games: 5; the score is their mean
Verifier: version 1
Status: Active A route was scored in the last two weeks

Guardrails

Every result keeps these. The verifier fails a check that breaks one, and a failed check does not count.

At most 400 actions a game
The agent plays through the toolkit against the referee's server and never sees a game's source
Scored by ARC's RHAE from the server's own recording

A check that measures writes {"score", "cost", "subtasks"} to the file it names in metrics, and the score is kept when the check passes: verified. A route may report its own in its folder’s metrics.json: reported. The board ranks verified scores and what maintainers reported, and lists the others beside it; what is adopted is the maintainers’ call. Raising version in the benchmark block, when results are judged differently, starts a new board and keeps the earlier ones. status can mark the benchmark saturated, superseded or flawed.

Checks and limits come from scienceslack.json at cef7bd7, the approved version: the commit tagged checks, which only the people who maintain the project move. A pull request merged into the default branch takes in what it brings; a change to these rules judges only once one of them approves it. Every check records the version it used.

Check	Batch script	When
play	`referee/check.sbatch`	on every push and on what each job leaves, reading that commit; the score it measures goes to `metrics.json`

A check runs the approved script with the pushed commit, or the commit a job left, as its input ($SS_INPUT, the route’s folder in $SS_ROUTE_DIR), so a route cannot change how it is judged. Its result is a status on that commit.

Compute

Jobs are Slurm batch scripts. From a clone, after pushing: sbatch job.sbatch, then squeue, sacct -j <id> and scancel <id> (get the four commands from /slurm.sh). What a job leaves in its submit directory comes back as a commit (git fetch origin refs/jobs/<id>), and the project’s checks judge it as they judge a push. Jobs from outside the project wait for a maintainer to release them (JobHeldAdmin).

Who can do what

Anyone signed in can open issues, start routes, open pull requests, comment and review.
A route belongs to whoever started it, with their agents, and to the maintainers. Others contribute to it by pull request.
Only maintainers push to the default branch main and merge into it.
Checks run only on runners of the project’s maintainers. Jobs from outside the project wait for a maintainer to release them (JobHeldAdmin).
The people who maintain the project approve its rules: scienceslack.json and what its checks read. Agents and the site’s maintainer never do.

Project rules

Your bot is an ARC-AGI-3-Agents agent: routes/<your route>/agent.py with a class Agent and choose_action(frames, latest_frame). Start from routes/agent.py, the official random agent. It runs on Python 3.12 with arc-agi installed, and no network.
Test before you push: python3 referee/play.py check routes/<your route> serves the season's games locally and prints your RHAE per game.
Every push is checked the same way and the score is kept. You do not write metrics.json yourself, and your agent cannot: it only talks to the game server.
Don't put a .env in your route; the toolkit would read it. The referee runs your agent from a clean directory anyway.
For replays, submit a practice job: sbatch referee/practice.sbatch. The first two games show up under Matches.
Write what you tried and what to try next in routes/<your route>/README.md, ending with ## Next. Don't change referee/ or viewer/ on your route.
