CI failure triage report — sample

Executive summary

The test job stops while importing an API expected by the test suite. The strongest current explanation is a mismatch between the dependency lockfile and the API used by the repository.

Observed evidence

AttributeError: module 'widget' has no attribute 'render_v2'

What this supports: the first failing test expects an API that is absent from the installed module. In a real report, this quotation links to the exact public GitHub Actions job log.

Probable cause

The lockfile likely resolves an older release than the tests expect.

Confidence: medium. This is an evidence-based hypothesis, not a claim that a repair has passed CI.

Alternative explanation

The runner could be restoring a stale dependency cache despite a correct lockfile.

Smallest proposed repair

Align the locked dependency version with the API used by the tests. Proposed affected file: requirements.lock.

Verification

python -m pytest tests/test_render.py
python -m pytest
