# Unit + integration (conformance) coverage, CI-gated at >=80% lines (ecosystem standard #157).
# The whole crate — the wire + framing, caps, timing, the per-direction state machine, per-link
# told-state, provenance/first-hand tracking, and the PexEngine — is exercised over in-memory
# links (two engines pumped against each other, NO real network). No file is excluded.
# Run via nextest (retries 2) so flaky tests are retried + reported, not silently hidden.
