Tested by building all h5n1-cattle-outbreak trees (n=9) locally.

Not asking for a change, just thinking through how this value can affect UX

Interesting how this tightly couples the Auspice config with this version of the workflow. If the auspice_config rule is changed in a way that fails to edit this value, the export rule will run into a validation error, which is a great check for us. On the other hand, if someone tries to use this config in another workflow (or older version of this workflow), they will also run into a validation error.

the export rule will run into a validation error

This was my thinking for this decision. I could have left it as "div" but wanted to avoid silent failures. Of the two downsides to this approach you point out,

if someone tries to use this config in another workflow

this is fair, although hopefully the text is a big enough hint to them that they have to add something on the snakemake side! They'll get validation errors if they forget

or older version of this workflow

given both the config and the snakemake pipeline are in version control I expect such usage to never happen, but 🤷

Mostly thinking of people who copy/paste configs without being fully aware of these internal nuances 🤷‍♀️

But yeah, I think the validation error is clear enough in this case

Validating schema of 'results/h5n1-cattle-outbreak/ha/default/auspice-config.json'...
  .display_defaults.distance_measure "__VALUE_OVERWRITTEN_BY_SNAKEMAKE_PIPELINE__" failed enum validation for ["num_date", "div"]

Thanks for looking through things Jover!
