I talked above about a 'cliff edge' being less about a direct economic one but much more a consequence of a regulatory cliff edge where what needs to be done is not known until just before it needs to be implemented.

That the government apparently released changed guidance for schools on Friday which is the last normal working day before they need to be in place this coming week is exactly the sort of 'cliff edge' impact I mean: it is impossible to act on anything in this guidance that differs from what went before - as it presumably does or there would be no point in issuing it.

I think that is a good indicator that is what we might look forward to at the end of December.
