I conclude:

Although this package remained the same, some checks that passed before fail now. This is most likely due to changes in dependencies: tiltIndicator and tiltToyData. I should try fix the issues then add a CI workflow in tiltIndicator and tiltToyData to avoid breaking tiltToyData.

[maurolepore]

For my own record. Here are some notable messages in the failed workflows. Nothing seems to point to toy data. I'll explore locally.
