Thanks, the strategy was the difference between our setups. I was running with 0.5.4 which does not yet include the switch to strategy 0 if gradients are provided. I am...

I noticed that the order in which auxdata is specified in `Workspace(...).data(...)`, given by ``` pyhf.Workspace(...).model().auxdata_order ``` is different from `config.par_order` (which is the order of parameters for fits), but...

With `par_order` now being alphabetically ordered in `pyhf` 0.7, is there any reason left for having `.parameters` in the API?

I gave this a try and this feature is extremely useful. It helps a lot with handling the mapping between `model.config.par_order` and the actual "flattened" parameters expected by `pyhf.pdf.Model.expected_data` etc.,...

The main use case I have in mind is holding groups of parameters fixed in the fit. With appropriate naming, I can get for example all indices of parameters called...

#1472 provides some motivation for typing of the tensor return values from the `pyhf` API.

My reading of "contrib" is "quite stable API, but might get factored out eventually", while I would view "experimental" more like "anything goes, expect things to break". You could of...

> 4.f(ABA,A) = AB (see rule 2. However, one may argue that the result should be BA. It depends on the starting point. I do not have any use cases...

Yes this works, an example of that is also discussed in this issue: https://github.com/scikit-hep/cabinetry/issues/382.

I just also ran into this bug: a single session in an event taking place in CST shows up as two sessions when viewed in CET, on both the day...
