A repeater identifying itself in CW over an FM carrier came back from the
recogniser as "2-2-2-3-3-5-2-7-0-5-9-7-0-8-1-0" -- one digit per tone,
sixteen characters of nothing, which cleared the five-character bar and
cost the capture its waterfall.
The rule now lives in one place, waterfall.is_readable, shared by the
scanner and the waterfall command: voice, no Morse, and more than a
handful of characters.
bandsaunter waterfall --check-morse
runs the CW decoder over the recordings a sidecar calls readable, for
sidecars written before the decoder could hear an ident over an FM
carrier, and draws -- and records the ident in -- the ones that have one.

Every capture that is not voice, or whose voice yields five characters
or fewer of transcript, now gets a PNG of the waterfall it would have
painted on screen: spectrogram from the IQ where it was kept, from the
demodulated audio otherwise, captioned and labelled either way.
The browser shows it in the picture panel, but only when there is no
transcript, Morse or decoded data to show instead.

draws them after the fact for recordings already on disk.
