@Pginer-WMF the issue on step 4 is new for me, should I create a new ticket for this?

Thanks for the details. Yes, please. a separate ticket will be helpful. thanks!

I have the same problem '⧼cx-mt-failed ⧽' when I try change from Apertium to Google Translator on a English to Spanish translation.

The broken message is caused by https://gerrit.wikimedia.org/g/mediawiki/extensions/ContentTranslation/+/8c432de1336166b321db1ec9a797f637cef8dc1b/modules/ve-cx/ui/actions/ve.ui.CXTranslationAction.js#82 / rECTX9c827eb3e9b7: i18n-ify some javascript error messages.

[mediawiki/extensions/ContentTranslation@master] Render the templates in a restored translation

https://gerrit.wikimedia.org/r/761292

After the above fixes, you can see template edits are restored and rendered correctly(Ignore the page reload delay due to debug mode with VE)

The above patches address templates(block and inline) alone. There are a few other special elements like References, Maths(T222699: Edits in mw:Extension/Math content is not saved) - editing them is not triggering a section a change and hence autosave is not triggered. If the section where these elements are present is edited, along with those changes reference updates, math updates get saved. The root cause for this is in the lack of edit detectors in the VE-CX integration code. Some of these classes does not expose interfaces to listen for edit changes. The references is a complex issue because it can be a template inside sometimes. There may be ways to fix this, but I think it would be difficult without the help of VE and Cite extension developers.

The severity for those elements is minimal though because reference content usually does not change across translations. Math formula's often does not require changes across languages. Inserting new reference or math anyways trigger save and hence not a problem.

VE Team, I used onAttributeChange method override to get events for template edits https://gerrit.wikimedia.org/r/c/mediawiki/extensions/ContentTranslation/+/761228/ But I don't see that interface in Math or other nodes. Is there a general approach that you can recommend to listen for content change events from those nodes? Edits in threse nodes should help CX to identify the section of these nodes and then triggering an autosave for the section. Is it possible to listen for edits from Surface class and then identify the source nodes and then traverse up to find parent section?

You probably shouldn't use events from the model tree to know if the document has changed. Those are mostly used just to update the view tree.

The only way to change the model is via a transaction, so you can just listen to ve.dm.Document's transact event. That will emit with a ve.dm.Transaction, which has a #getModifiedRange method. You can use that to work out what section(s) was changed: find the node in the DM tree with the start offset and traverse up to the section. You may also want to find the section for the end offset, as in theory you could have a transaction that spans multiple sections (?), then update all sections between start & end.

Thanks, I followed your advice and updated https://gerrit.wikimedia.org/r/c/mediawiki/extensions/ContentTranslation/+/761228 accordingly. Would you please review?
