Find what a show says every week, and publish it as the show's own audio

The text analogue of the audio scan, and it costs nothing: the server already
holds transcripts for eight episodes of each show, mirrored within a minute of
each other, carrying one campaign and eight different programmes. Text several
of them share is not the programme.

It reaches where subtraction cannot. Subtraction needs a second description of
one episode -- a publisher's transcript or a second fetch -- and 18 of 337
mirrored episodes have one. This needs only the episodes already held. Measured
against the length gap on the live library: Heavyweight 111%, Incels 105%, Ezra
Klein 92%, Tangle 83%, against refetching's 21% on the same show.

**It is published as the show's own audio, not as advertising, and that is a
measured limit rather than caution.** What recurs is a show's sponsor reads and
its furniture together -- its welcome, its break cue, its credits -- and I tried
to separate them and could not. Scored against the 404 recurring stretches in
episodes that also hold a publisher's master, which says which is which:

    ad copy markers   5% of the advertising, 4% of the furniture
    length            mean 51s against 29s, overlapping throughout
    position          ads 62 open / 176 mid / 41 close
                      furniture 12 open / 61 mid / 52 close

A first classifier built on ad copy agreed with the master 33% of the time and
called 263 advertisements furniture. None of those signals separates the two.

So the detector claims only what it measured: this is text the show says every
week. That is what KindCue means, and it leaves the listener's setting in charge
-- a show's own audio is skipped by preference, advertising unconditionally, and
claiming the stronger of the two on a coin flip would be the worse mistake.

Refused when more than 35% of an episode recurs, the same share the ad scan
refuses at: a re-aired episode or a formulaic segment would otherwise be eaten
whole. Guarded by share rather than by the length gap, because the episodes this
is worth most on are the ones with no gap at all -- a show that bakes its reads
into what it publishes declares the length it serves, so the gap is blind to
every advertisement in it.

Skipped entirely for an episode that already has measured advertising. The
better answer must not be overwritten by the vaguer one.
