1. Fixed Dependency Resolution Error (pyproject.toml)

Problem: The workflow failed with resolution-too-deep error when trying to install pr-arena==0.2.9 due to conflicting dependency constraints between firebase-admin 7.x, openai 2.x,
and openhands-ai 0.40.0.

Solution: Updated dependency constraints to allow compatible version ranges:

• firebase-admin: Changed from ^6.6.0 to >=6.6,<8.0 (allows 7.x versions)
• openai: Changed from >=1.99.5,<1.109.0 to >=1.99.5,<2.8.0 (allows 2.x versions)
• Added explicit constraints to prevent conflicts:
  • google-api-python-client = ">=2.164.0,<3.0.0" (required by openhands-ai but removed from firebase-admin 7.x)
  • google-api-core = ">=2.0.0,<3.0.0"
  • protobuf = ">=4.21.6,<5.0.0"
  • urllib3 = ">=2.0.7,<3.0.0"

2. Fixed Linting Error (resolver/analysis/get_data_from_firebase.py)

Problem: Bare except: clause at line 186 violated ruff's E722 rule.

Solution: Changed except: to except Exception: to explicitly catch exceptions.

3. Updated Workflow to Install from Branch (.github/workflows/pr-arena-resolver.yml)

Problem: Workflow installs from PyPI (pr-arena==0.2.9) which still has the old dependency constraints.

Solution: Changed installation command from:
pip install pr-arena==0.2.9
to:
pip install git+https://github.com/neulab/pr-arena.git@beta-test

This allows the workflow to use the fixed dependencies from the beta-test branch without requiring a new PyPI release.

4. Regenerated Lock File (poetry.lock)

Updated poetry.lock to reflect the new dependency constraints and ensure reproducible builds.

Verification:

• ✅ poetry lock completes successfully (no dependency conflicts)
• ✅ All pre-commit checks pass (ruff, mypy)
• ✅ All tests pass (90 passed, 1 skipped)
• ✅ Package builds successfully with poetry build
