The escalation-rate flip (100% idle, 0% load) is at N=1 idle vs N=12 load. Is N=1 idle adequate to report this finding, or do we need ≥3 idle bursts before locking?As I have observed the behaviour previously without accurate measurements, the "user observes problem means with a confidentiality of p = 0.9 that the problem exists". No further measurements needed, as the issue is also tedious to reproduce like watching a kettle get to boiling point or watch grass grow.

Anything in Phase 3 above flagged as "not yet measured" that would be cheap to add before Phase 4? Specifically:- Should ftrace mac80211/cfg80211 events be enabled before next rep? Cost: ~10x journal volume. Benefit: bottom-half timing for the 100ms-scale stalls in the 109s blackhole.Good idea.

Is the lack of AP-side capture (no Fritz!Box logs) a blocking gap, or can the campaign proceed without it for now?The campaign can proceed without, as we would have to prepare an AP ourselves which is not guaranteed to reproduce the problem. Fritz!Box devices are opaque when it comes to low level WiFi logging.
