codecov.yml

# Codecov configuration.
#
# Background: during the Codecov -> Harness migration the patch/diff line
# attribution became unreliable for this repo — Codecov reported lines as
# uncovered (e.g. the whole of Gate::classify_upgrader_effect() and
# Sudo_Session::set_pending_login_token()) that are demonstrably executed by
# passing unit tests, including a covered caller (Plugin::capture_login_session_token)
# invoking a callee Codecov marked uncovered. Codecov's own report flagged the
# cause: base and head commits had a different number of coverage uploads
# (base 2, head 1), because the coverage job runs on both `push` (base, on
# main) and `pull_request` (head), so a merged SHA is built twice.
#
# This config has two goals:
#   1. Make the status checks tolerant of that measurement noise so they do not
#      block on false-negative diffs.
#   2. Make per-commit upload counts deterministic so base/head comparisons are
#      apples-to-apples and the "different number of uploads" warning stops.
