OK you are answering at a level more detailed than I raised and seem to assume I didn’t consider such things. My reason and IMO the expected reading of “SUSY has failed” is not that such particles have been ruled out as I know they havn’t, but that its theoretical benefits are severely weakened or entirely ruled out according to recent data. My reference to SUSY was specifically regarding its opportunity to solve the Hierarchy Problem. This is the common understanding of one of the reasons it was proposed.
I stand by my claim that many/most of the top physicists expected for >1 decade that it would help solve such a problem. I disagree with the claim:
“but I think the smart physicists knew all along that those were just plausible hypotheses worth checking, ” Smart physicists thought SUSY would solve the hierarchy problem.

Common knowledge, from GPT4:
“can SUSY still solve the Hierarchy problem with respect to recent results”
Hierarchy Problem: SUSY has been considered a leading solution to the hierarchy problem because it naturally cancels out the large quantum corrections that would drive the Higgs boson mass to a very high value. However, the non-observation of supersymmetric particles at expected energy levels has led some physicists to question whether SUSY can solve the hierarchy problem in its simplest forms.
Fine-Tuning: The absence of low-energy supersymmetry implies a need for fine-tuning in the theory, which contradicts one of the primary motivations for SUSY as a solution to the hierarchy problem. This has led to exploration of more complex SUSY models, such as those with split or high-scale supersymmetry, where SUSY particles exist at much higher energy scales.

IMO ever more complex models rapidly become like epi-cycles.
