qwen3-30B-A3B-Instruct-0617-plateau-6skill-nocorpus — generated environments
Environments generated by the SPARE proposer during training run
5uui7594 (qwen3-30B-A3B-Instruct-0617-plateau-6skill-nocorpus), recovered from the spare-viz durable cache.
The run's scratch directory no longer exists; this dataset is the surviving copy.

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/difficultyare parsed from the proposer prompt, not from a stored label.
