# Bun test configuration.
#
# coveragePathIgnorePatterns: exclude the worker-thread multi-node TEST
# HARNESS from the coverage denominator.  These files are testing tools
# (used to *write* tests), exercised only by the ParallelMultiNodeSpec /
# parallel-pubsub suites — which are quarantined on GitHub's hosted
# runners because Bun there can't respawn functional worker threads after
# the first test (#538).  They run + are covered locally and in Docker;
# gating CI line-coverage on infra that can't execute on the hosted runner
# would be a false signal.  Product code (incl. LeaseMajority, the cluster,
# persistence) is unaffected.
#
# This block goes away with the quarantine.  `nightly-flakes.yml` measures
# whether it still has to stand and carries the decision path (14 consecutive
# green nights); `docs/…/testing/diagnosing-flakes.mdx` states it in prose.
