MathConstructOptimize-Envs (Harbor)

The 3,577 tasks of amphora/MathConstructOptimize-Envs as runnable Harbor environments. Each task is one directory:

tasks/<task_id>/
  task.toml              # metadata (subset, family, problem_key, tier, level, source, license, tags,
                         #   direction/baseline/best_known for optimize), limits, network_mode = "no-network"
  instruction.md         # the prompt; the agent writes its answer to /workdir/answer.json
  environment/Dockerfile # python:3.11 slim + pinned numpy/scipy/sympy/networkx/pysat/z3/pulp/ortools
  environment/instance.json
  tests/test.sh          # runs tests/run.py + tests/check.py, writes /logs/verifier/reward.txt
  solution/solve.sh      # oracle: a known valid answer

uv tool install harbor
huggingface-cli download amphora/MathConstructOptimize-Envs-harbor --repo-type dataset --local-dir mcoe
harbor run -p mcoe/tasks -a oracle -n 16          # validate: every task scores > 0
harbor run -p mcoe/tasks -a terminus-2 -m <model> -n 16

Validation:

• The oracle agent passes on all 3,577 tasks (construct = 1.0, optimize ≥ 0.1), and a no-op agent scores 0.
• An HTTP canary confirmed that no-network blocks internet access inside the task container. Research-level best constructions are public, so do not relax this for RL.
• If you run many trials concurrently, raise Docker's default address pools. Each no-network task creates its own networks, and the defaults are exhausted at roughly 30 concurrent trials.
