Fast radio bursts last milliseconds; CHIME/FRB’s January 2026 catalog has 4,539 bursts from 3,641 sources. Full-fidelity baseband (voltage/phase) data cannot all be kept—software decides in seconds what to save. A missed trigger is worse than a wrong label: intensity summaries cannot recover lost phase, so a source may stay visible while the data needed to locate or dissect it are gone.

AI already helps (a 2018 network found 72 extra pulses from FRB 121102). The authors want ML to flag and hold, then classical checks (dedispersion, RFI, a second pipeline). Their small Effelsberg test on FRB 20200120E cutouts: searching ~¼ of the dispersion grid looked cheaper but recovered 88.75% of blinded injections vs 90% for the full classical baseline, missed two the baseline caught, found none extra, and was slower (~29 ms vs ~21 ms). A speed-up that fails the full chain should not ship. Same bar for future quantum claims.

Treat detection code as part of the telescope: injection tests, log every model change, keep a conventional path, reserve disk for “unknown, preserve,” and sample windows that did not trigger. Denoised or gap-filled pulses are not measurements. Reward retained evidence, not only latency. The worst error is a strange, low-confidence burst overwritten—no later model can study a file that no longer exists.

As telescopes automate the search for fleeting cosmic signals, algorithms must be judged by the evidence they preserve as well as the events they find.

A telescope can register a cosmic signal and still lose the evidence needed to understand it. In an automated observatory, software may decide within seconds whether the richest record is saved or overwritten. An algorithm can therefore improve a speed benchmark while narrowing the universe that future researchers are able to study.

The stakes are clear in fast radio bursts, or FRBs: intense radio flashes, often lasting only milliseconds, that help astronomers investigate extreme objects and the matter between galaxies. The second CHIME/FRB catalog, released in January 2026, contains 4,539 bursts from 3,641 sources. Such surveys make automated processing indispensable. They also make its selection decisions scientifically consequential.

Radio telescopes cannot simply save everything at full fidelity. Rich voltage records, known as baseband data, retain phase information that intensity summaries cannot recover. CHIME/FRB’s triggered recording system, for example, temporarily buffers these data and saves selected windows when its detection software identifies an event. If a trigger arrives too late, or never arrives, that opportunity can disappear.

This makes a missed preservation trigger different from an ordinary classification error. A........
