  "abstract": "Optical neutrino telescopes reduce the photomultiplier signals of an optical module or string segment to compact multichannel summaries, and readout loss can make these summaries unreliable. We asked whether availability-based quality gates, which accept a summary when enough of the readout was live, can certify a summary of inter-channel statistical consistency (called coherence here; not optical coherence) under readout loss, and where they fail. We used public IceCube pulses (9,484 string records) and the released hits of KM3NeT event KM3-230213A with controlled readout loss, together with a replay of real KM3NeT readout flags. In a two-by-two design we compared a published recursive support state with direct mask support, and calibrated every threshold on development records. The support state is a function of the mask and added no information. On IceCube the support-gated rule retained 0.16 percentage points more usable summaries, an effect of the window at which support was read that reversed sign at a looser tolerance; on KM3NeT it accepted nothing. The gates accepted only records with nearly intact masks, including records whose charge had been depleted by signal-dependent loss that the mask does not record. Pulse loss during live acquisition and timing jitter passed every availability gate, which then accepted summaries of which up to 66% were unreliable. Availability flags are therefore necessary but not sufficient, and signal-based checks are needed. This work uses public data and is not an IceCube or KM3NeT Collaboration result.",
