My attentive observations also indicate the problem isn't solved by redefining the terminology.
Things breaking doesn't necessarily imply it is not perpetual.
Let me reiterate an old idea (spoiler: it includes 'heat')
Things can break before "their time", or things can break way after "their time".
Perhaps, in the light of breaking things, we should define this "duration of things", so we could figure out at what point this "breaking" transforms from a nuisance to an actual critical operational component....
Sure we define that word "critical" as "essential", with the meaning "a way to extract useful potential energy" from the breaking process (whatever that may be).
Why would one want to wield a wooden wheel when, who-knows-how, this wooden widget would wear-out as a way of perpetualizing whirlings of that wheel?
Perhaps Bessler smashed his wheel for a technical reason (maybe extracted/evaporated moist made it brittle), while we all assume it was emotional rage.
For deserving the definition "perpetual" it better be that such wheel is capable of providing more energy in operation than the effort of building that construction in the first place plus the energy of burning that wood..... otherwise it would clearly break (-even) before its time, so we could just have burned that stack of wood as was delivered and be relaxed about it.
But I think the now newly introduced term "unstable perpetual motion" can be defined as being capable of providing at least the same amount of energy in its constructed form, as otherwise could have been extracted in its raw form plus the energy to create such construction plus any other potential or kinetic energy it may receive.
