The purpose of showing the source link is to allow exploration. That can be useful in some contexts where you may need to navigate to other articles to get information about them, and also keeps things consistent. T102115 definitely needs to be fixed, but it is not "caused" by this.

Card pairs should show articles for equivalent concepts always ("Gos" in Catalan and "Dog" in English in your example). Showing articles that happen to have the same name in different languages just adds confusion. If the source article does not exist, we won't show the source card as an indication of that (later we can consider to allow user to mark it as a translation for later once T96147 is in place).

OK, I agree that a source link card can be shown, if:

• There is an article in the target wiki with the selected text.
• There is an article in the source wiki with the corresponding topic.

So, in the case of translating from English to Catalan, selecting "Gos" in the target column must show en:Dog and ca:Gos.

Removing from the sprint, but should be tested after resolving T85932.

Adding to the sprint for Runa to test.

@Amire80 can you please check? I don't think this is the expected result. Do note, automatic link adaptation however points to the correct source link card i.e. en:Dog.

Indeed, still a bug, but probably not a high-prio any longer. The source card should match the target card, and this should be fixed, but what is more important is that now if the target link doesn't exist, we suggest adding a red link rather than a link to a wrong article, so this is not as destructive as it used to be.
