Split canonical coverage suite (-l -m -e --coverage) round-robin across 4 matrix shards using --shard INDEX/4 (existing external sharding). Shard 0 runs unit+regression slice, shards 1-3 regression-only to avoid duplicating unit runtime. Each shard stages .cov*/.coverage* via find+cp --parents into cov_staging and uploads as coverage-data-N. New coverage-combine job downloads all shards, flat-copies into libensemble/tests, runs coverage combine + coverage xml, and uploads single coverage.xml to codecov. Cuts ~3-4x wall time; union is exact (105 standalone files round-robin, no gap/overlap). Also mirrors timings per-shard for debugging.
