The Python workspace already runs pytest-cov in CI but with no
threshold and inline-flagged config. CI run 24956647701 (2026-04-26
staging) reports 97% coverage on the package — well above the issue's
75% target. The actionable gap is locking in a floor so a regression
can't sneak past, and centralizing config so local `pytest` matches CI.
Changes:
- workspace/pytest.ini — coverage flags moved into addopts (-q,
--cov=., --cov-report=term-missing, --cov-fail-under=92).
92% = current 97% measurement minus the 5pp safety margin
the issue's Step 3 prescribes.
- workspace/.coveragerc (new) — [run] omit list and [report]
skip_covered. coverage.py doesn't read pytest.ini sections, so
the omit config has to live here.
- .github/workflows/ci.yml — removed the inline --cov flags from the
Python Lint & Test step; now reads from pytest.ini. Workflow stays
the same single-command shape, just simpler.
Result: any PR that drops coverage below 92% fails CI loudly. Floor
ratchets up by replacing 92 with current measurement on a future
test-writing pass — same shape as Go coverage gates landed elsewhere.
