# MaxText Codecov Configuration
#
# We use a two-flag scheme ('regular' and 'scheduled') to handle our tiered test suite.
# 'carryforward' is enabled because Pull Requests only run a subset of tests (excluding 'scheduled_only').
# Without it, PRs would show a significant coverage drop as they would 'overwrite' the full-suite results.
#
# Scheme:
# - 'regular': Updated by every PR/Schedule. Used to evaluate 'patch' (new code) coverage.
# - 'scheduled': Updated ONLY by scheduled full runs. Used to anchor 'project' (total health) coverage.
# During PRs, the 'scheduled' flag is carried forward from the last full run on 'main' to keep the score stable.

# Exclude non-source code, deprecated and experimental folders from coverage tracking
