Okay, so maybe this is what I was remembering. So you can't ditch the
SRBs from the tank but you can ditch the SRBs and tank from the
orbiter, right?

So now, we have two contradictory claims - it's either survivable or
it's not.

It is not thought to be survivable.

Here's a reference from General Dynamics. Note that lack of survivable fast
separation during SRB firing was one of the arguments for replacing them
with liquid rocket boosters.
