# qwen3-30B-A3B-Instruct-0617-plateau-2skill — generated environments

Environments generated by the SPARE proposer during training run
`zbfsdp1a` (qwen3-30B-A3B-Instruct-0617-plateau-2skill), recovered from the spare-viz durable cache.
The run's scratch directory no longer exists; this dataset is the surviving copy.

| | |
|---|---|
| Games | 308 |
| Steps covered | 11 (step 0–364) |

## 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:

```python
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.
