codecov.yml

# Codecov configuration.
#
# Coverage (issue #20) sits at ~99%. The project target is fixed at 99% and
# every patch must be fully covered, so new code keeps the total there. The
# small remainder is unreachable defensive code and one-way/loop-back branch
# halves that are not worth contriving inputs for; they are left uncovered
# rather than hidden behind coverage pragmas.
coverage:
  status:
    project:
      default:
        target: 99%
        threshold: 0.5%
    patch:
      default:
        target: 100%

# Coverage is uploaded from several jobs, each with its own flag: unit (the
# pytest suite), shapes and cells (real generator runs on the example projects).
# Codecov merges them per commit. carryforward keeps a flag's last coverage when
# its job does not run on a given commit, so the combined total stays stable.
