Workbench (v4 task set: finance traps + protected reward)
An OpenEnv environment that trains workspace habits in a run_bash / submit sandbox, built for OpenEnv Arena.

Tasks (9)
Finance (3), new in v4
- loans-easy / medium / hard. Month-end loan-loss provisions: stage loans by days past due, apply provision rates, write
provisions.json.- Late caveat: a dated risk-committee memo changes a rate (superseded on hard) or declares returned payments.
- False premise: the CFO names three "written-off" loans, and usually 1–2 are not in the register. Follow the records and list those loans as discrepancies. In 25% of instances the CFO is right.
- Hard adds: a future-dated memo, payments recorded after the reporting date, and FX.
Software (3)
- pyrepo-bug1 / implement. Real bugs in vendored toolz / boltons / tabulate / inflection, graded by the complete pristine test suite.
- repair-medium. A synthetic billing package with SPEC and CHANGELOG, and hidden tests.
Office (1)
- expenses-easy. A policy audit.
Industrial (2)
- reflow-hard. A reflow-oven audit.
- downtime-medium. A sensor-log downtime audit.
Reward
- 0 if any protected check fails: broken output schema, a changed input file, a test that passed before now failing, an edited test, or the decoy "fixed".
- Otherwise full success = 0.9 + 0.1 × steps_left / 12.
- Otherwise partial = 0.5 × share of checks passed.
The reward always lies in [0, 1].
Calibration
Qwen3.8-27B, thinking off, 12,288-token completion budget, 8 episodes per task, counting full solves:
| task | strict JSON | lenient JSON |
|---|---|---|
| pyrepo-bug1 | 1/8 | 3/8 |
| pyrepo-implement | 2/8 | 1/8 |
| repair-medium | 2/8 | 2/8 |
| loans-easy | 0/8 | 5/8 |
| loans-medium | 0/8 | 5/8 |
| loans-hard | 0/8 | 4/8 |
| expenses-easy | 1/8 | 3/8 |
| reflow-hard | 3/8 | 0/8 |
| downtime-medium | 2/8 | 3/8 |
Strict failures are almost all format: prose before the JSON, unescaped quotes, <tool_call> tags.
Licences
The vendored libraries keep their own licences: toolz and boltons are BSD-3-Clause, tabulate and inflection are MIT.
