When a section is blanked using 'Do not use MT', we consider the content to be the user creation so it should be counted as manual content. Not showing MT warning for the paragraph, and contributing to the percentage of manual modifications for the overall progress calculation.

If the paragraph is blanked using 'Do not use MT', but no content is added I don't think it should compute as a full paragraph translated by a human. That is, adding two paragraphs with 100% MT, should not be compensated by adding 10 empty paragraphs.

@Pginer-WMF So, if a section is blank, and if we are not considering it as a human translated section, should it be restored as blank section or present with a section placeholder?

I think both positions make sense:

• We could keep them to capture the explicit intent of the user to indicate that this section should be empty.
• We could ignore them since the final result is the same as keeping the placeholder when publishing, and it may avoid future surprises if the user tries to add the paragraph later (i.e., consolidating the placeholder as a starting point).

I'm more inclined towards the later, presenting the empty section as a placeholder when it gets reloaded. But I'm ok to go the other way if it makes things easier technically.

@Pginer-WMF, as per https://gerrit.wikimedia.org/r/454525, this is the behavior I implemented

1. if a section has blank content, it is not counted as a translated section for progress calculation. So if all sections of of a translation are blank, the total progress is 0%. If you translated 23 sections and all from MT with no modification, the progress is "23 sections translated 100% unmodified MT". After this, if I use "Don't use MT' for 3 sections, the progress is "20 sections translated, 100% unmodified MT"
2. But, it will be considered for saving and restoring. So blank section is saved and restored as blank section. Not as placeholder. The translator is free to change that blank section using any of the MT provider or from source or scratch as per the preference.
3. A blanked section is not validated for MT abuse.

Do you see any issue with the above implementation?

No. The behaviour makes perfect sense to me. Thanks for the clear summary!
