qwen3-30B-A3B-Instruct-0617-plateau-6skill-nomem — generated environments

Environments generated by the SPARE proposer during training run z1wnr4j9 (qwen3-30B-A3B-Instruct-0617-plateau-6skill-nomem), recovered from the spare-viz durable cache. The run's scratch directory no longer exists; this dataset is the surviving copy.

Games 3746
Steps covered 170 (step 0–358)
With recovered skill 3692
With hint 0

Layout

manifest.json                                  authoritative games list
games/gen_<NNNN>/game_<NNNNN>_<NNN>_<slug>.py  one environment per file

generation numbers are dense over the training steps actually captured; the true training step is the step field. Each game exposes the standard SPARE contract (reset(seed=None), step(action) -> (obs, reward, terminated, truncated, info)).

Loading

Load games through the project loader, not a bare import — it injects the common stdlib names and the ToolUseBaseEnv / TerminalBaseEnv base classes that generated games subclass without importing:

from spare.core.envs.synthetic_game_env import make_synthetic_env
env = make_synthetic_env("games/gen_0000/game_00000_000_api_orchestration.py")
obs, info = env.reset(seed=0)
obs, reward, terminated, truncated, info = env.step("...")

Caveats

  • Partial step coverage. The viz extractor pulls newest-first with a call budget, so a run's captured steps are a subset of the steps it trained.
  • No joined rewards. Weave payloads for these runs predate the reward join; mean_reward/solve_rate are null where reward_joined is false.
  • skill / difficulty are parsed from the proposer prompt, not from a stored label.
