The error value.reason

user: the script can change it: the error says what happened in the experiment’s names, and what to write instead.

Where MIME gives it, with what its message says happened and what its action says to do ({…} is filled in from the experiment):

• in mime/materials/_values.py:

  • what happened: the declared value {…}'s reason: {…}

  • what to do: declare it with its reason: declare({…}, ..., reason="where the number comes from"), or leave it for later with reason=pending()

Reading an error and reaching its full traceback: reading an error. Every code: the index.
