The vote suite grew from 375 tests (39.1 min on one runner, 2026-09-30)
to 1,321, so a single-runner vote can no longer finish. Run it as the
same ten duration-planned shards playwright-mock.yml uses; each shard
logs the specs it executed and the codegraph shadow unions them into
one trial. A shard that runs out of its 28-minute test budget logs only
its failed specs, never clean ones.
