The tick arm runs twenty-six housekeeping steps in sequence on the one runtime thread, and is polled last, so anything slow in it holds up inbound packets, TUN traffic and control commands behind it. Field evidence says that happens for over a second at a time, but the attribution behind that is two months old and predates the connect-on-send gate, the control read isolation, and the peer lifecycle rework. This measures it rather than continuing to reason about it. Per step it records exact count, max and total into fixed static counters; a dedicated writer thread drains them every ten seconds to a TSV under /var/log/fips, one file per capture, capped at 32 MB. Nothing accumulates: the counters are swapped to zero each interval and the thread holds no history. Arming is `fipsctl profile tick on`, served in the control accept task so the toggle cannot queue behind the very behaviour it measures, and it does not survive a restart. The whole thing is behind a Cargo feature that is off by default, because the risk worth eliminating is the twenty-six edited call sites in the hot loop. With the feature off the macro expands to the bare expression, which makes the default build's neutrality something you read off the generated code rather than something a benchmark fails to disprove. The measurement that matters is how late each tick is against the deadline it was scheduled for, since the arm is polled last and that lateness is the delay. Two earlier designs derived it from the interval between entries and both under-reported: the schedule is fixed, so a steady delay leaves every gap exactly one period and any gap-derived figure reads zero under precisely the sustained overload this is meant to find. The interval hands back its own deadline, so the delay is now a subtraction with no model behind it, and a test drives three late ticks at a constant gap to keep it that way. CI gains a default-features clippy and a feature-on build and test on both runners, closing the gap left by clippy already running with all features.
