# Unit + integration (swarm) coverage, CI-gated at >=80% lines (ecosystem standard #157). The
# whole DHT — k-buckets, iterative lookup, provider store + TTL/republish, the wire, and the
# service RPCs — is exercised over the in-memory swarm harness (many virtual nodes in one
# process, NO real network), so every module is counted. No file is excluded from the gate.
# Runs via nextest so a flaky test (fail-then-pass) is retried + reported, not silently
# counted as a plain failure (#489).
